TCE and PCE contaminating Superfund sites in Woods Cross and Bountiful (UT)
by Neil Fischbein on Sunday, March 30, 2008 [Permalink] [0 Comments]
The Deseret Morning News (UT) reports:
Drinking water supplies for tens of thousands of people near three active Superfund sites in the Bountiful and Woods Cross areas have been at risk or even polluted because of groundwater contamination.

The pollution is so bad that the federal government decided to join state regulators in directing long-term cleanup efforts of those sites.

Business owners who bought property in the affected areas, but were unaware that sources of contamination within the Superfund sites were beneath them, are expected to pay for removal of tainted soil and old polluting underground tanks that were put in long before they came along. Federal funds for cleanup are available for Superfund sites if they are active on the Environmental Protection Agency's National Priorities List, but some property owners still pay.

Utah Division of Drinking Water director Ken Bousfield said last week that water suppliers in Bountiful and Woods Cross are, based on the most recent tests, providing clean drinking water. Bousfield also is aware of the plumes of contaminated groundwater in those areas and how test results can change.

"That's why you monitor," he said.

The EPA lists at least 14 active Superfund sites in Utah that are among the worst hazardous waste sites in the country. Two sites in the Woods Cross and Bountiful areas are active due to three plumes of groundwater polluted by chemicals used in the past by dry cleaners, automotive garages and other industry.

Aberdeen Contaminated Ground Water site proposed for addition to EPA's Superfund (NC)
by Neil Fischbein on Tuesday, March 25, 2008 [Permalink] [0 Comments]
According to this recent EPA press release:
The Aberdeen Contaminated Ground Water site in Aberdeen, North Carolina has been proposed for addition to EPA’s National Priorities List (NPL) of hazardous waste sites. It is one of six hazardous waste sites to be proposed for addition to the NPL, while twelve sites nationally are being added to the list.

The Aberdeen Contaminated Ground Water site is about 1 acre in size and located on highway Route 211 in Aberdeen, Moore County, N.C. Powdered Metal Products (PMP) manufactured precision machine parts at the facility from 1980 until 1995. The operation utilized a trichloroethene (TCE) dip-vat as part of the manufacturing process. During the investigation of ground water contamination at the Geigy Chemical Corporation NPL site in 1990, which is located just on the other side of State Route 211, TCE, lead and pesticide contamination was detected in numerous private wells along Crestline Lane and Route 211. Investigations have identified contaminated soils in the vicinity of the former TCE dip-vat utilized by PMP as the source of TCE contamination in the ground water.
In a follow-up article in The Fayettville Observer (NC), we learn:
Trichloroethene also was detected in the town’s municipal water supply wells No. 5 and No. 9, according to an EPA report [PDF]. The level of the chemical exceeded the federal Safe Drinking Water Act maximum contaminant level.

The report said the town took the wells offline for some time and is now blending water from those wells with water from other municipal wells to reduce the trichloroethene levels.

The EPA provided municipal water supplies to 56 residences and businesses in the area, according to the agency.

Behr site proposed as Superfund site, Cancer incidence inquiry planned (OH)
by Neil Fischbein on Friday, March 21, 2008 [Permalink] [0 Comments]
Recently, the Dayton Daily News (OH) reported the Behr Dayton Thermal Products Plant has been proposed to EPA's National Priority List (NPL) for clean-up:
Groundwater contamination in the vicinity of the Behr Dayton Thermal Products Plant is severe enough to merit putting it on the National Priority List of the U.S. EPA's Superfund program, federal officials said.

The list represents the highest level of urgency for cleanups in the nation.

If the U.S. Environmental Protection Agency approves later this year, an effort to cleanup groundwater at the site would rank among five others in Montgomery County on the National Priority List.

There are 22 active Superfund sites in the county where work is being planned or is under way.

Priority sites are considered the worst in the nation in terms of hazard and are eligible for cleanup using Superfund Trust money. The Behr project is still in the investigational stages, which typically can take two years and cost millions, officials said.

So far, the contamination has led to the closure of McGuffey Elementary School, 1032 Webster St., and the installation of air evacuation systems in 100 homes affected by indoor air fumes from the groundwater, which is tainted with the degreaser trichloroethylene — TCE — and other organic chemicals.

It's unknown when the school will reopen. A handful of homes that have dirt basements still have indoor air contamination slightly above strict exposure levels. In the Superfund program, those responsible for the contamination fund the cleanup.

According to documents obtained by the Dayton Daily News, federal investigators believe four industrial businesses could share responsibility: Gem City Chemicals Inc., Aramark Uniform Services, Chrysler, and Behr Dayton Thermal Products.

Aramark didn't return a call for comment. Gem City declined comment.
In a follow-up article, the Daily News also reports that a survey of local cancer incidence is planned:
Public Health Dayton & Montgomery County is launching a cancer incidence survey among residents near the Behr Dayton Thermal Products plant, where groundwater pollution has prompted regulatory action to address indoor air quality.

Mark Case, director of environmental health for the agency, said Monday, March 10, that the survey could take up to a year and is being conducted with the Ohio Department of Health.

The survey will examine medical records and compare cancer levels in the neighborhood with overall cancer levels in the county, state and nation, he said. "By comparison, you get a sense whether something is out of line or not," Case said.

The Ohio Cancer Incidence Surveillance System will be tapped for data, he noted. All diagnosed cancer cases in Ohio are supposed to be reported to the system. The area will include the census tract of the Behr plant and residential neighborhoods where 100 or so indoor air vapor abatement systems have been installed.

A similar survey was performed in 2005 in Kettering neighborhoods near the former Gentile Air Force Station. Residents of the Wiles Creek neighborhood there complained about pollution from the former Defense Electronics Supply Center. The survey found no abnormalities.

Case acknowledged that a cancer survey could have some limitations.

"We don't know how long the vapors have been in people's homes," he said.

The exact chronology of Behr plant pollution is unclear. Former plant owner Chrysler has said it discovered TCE, or trichloroethylene, contamination in 1996, but it wasn't until Ohio EPA tests in 2006 that hazards to homes were suspected.

Cancer can develop over decades and take the form of many different types of tumors, Case said. In its Ninth Report on Carcinogens, the federal National Toxicology Program determined that TCE is "reasonably anticipated to be a human carcinogen." The International Agency for Research on Cancer has determined that TCE is "probably carcinogenic to humans," according to the Agency for Toxic Substances & Disease Registry.

In a related development, a community outreach survey sponsored by the Environmental Sustainability Research Group at the University of Dayton will examine health problems in the area. A public meeting on the survey could occur in April, a spokeswoman said.

3 toxic site clean-ups in Rochester/Brighton (NY)
by Neil Fischbein on Friday, March 21, 2008 [Permalink] [0 Comments]
Though the meetings announced in this article have since passed (the article was originally dated March 10), this Rochester Democrat & Chronicle article highlights 3 separate site clean-ups that are under way:
Costly taxpayer-financed plans to address toxic-chemical contamination in residential pockets of northeast Rochester and central Brighton will be detailed at separate public meetings this week.

The state Department of Environmental Conservation has scheduled a meeting for Tuesday evening to discuss a $1 million proposal to remove tainted soil and take other steps to address contamination at a now-closed business at Fernwood and Portland avenues in northeast Rochester.

The DEC first learned in 2000 that Preferred Electric Motors had spilled solvents and other potentially harmful materials in the course of its work refurbishing electric motors. Trichloroethene (TCE), tetrachloroethene (PCE) and other solvents are contaminating groundwater near the former business, prompting the state to install ventilation systems in two homes to guard against the build-up of toxic vapors.


Clean-up of Fernwood Ave site planned in Rochester (NY)
by Neil Fischbein on Friday, March 21, 2008 [Permalink] [0 Comments]
The Rochester Democrat & Chronicle (NY) recently reported this news:
Barring a flood of public comments, state environmental officials could decide early next month on a cleanup option for a site in northeast Rochester where soil and groundwater are contaminated with toxic solvents.

And judging by attendance at a public meeting on the site Tuesday evening, a flood of further comments is unlikely. "It's sad in the neighborhood — there's just no interest," said Sue Buehner, one of two or three citizens who attended the meeting in the library at School 36.

The session focused on problems at 42 Fernwood Ave., a small commercial building where Preferred Electric Motors reconditioned motors from the early 1950s until the business closed eight years ago. In the process, the company spilled or dumped toxic solvents, including trichloroethene, or TCE.

After an anonymous tip about leaking chemical drums in 2000, state Department of Environmental Conservation officials found solvents in soil and groundwater.

They also discovered very high levels of TCE vapors infiltrating a neighboring rental home, and health officials ordered that it remain unoccupied until a system was installed to pull the potentially harmful vapors from the soil.

Army Corps of Engineers and TCE in Cheyenne (WY)
by Neil Fischbein on Wednesday, March 19, 2008 [Permalink] [0 Comments]
The Wyoming Tribune-Eagle reports that the Army Corps of Engineers has agreed to take over clean-up of TCE resulting from a FUDS (Formerly Used Defense Site):
The Army Corps of Engineers will apparently “do the right thing” when it comes to taking responsibility for treating one source of Cheyenne’s drinking water for trichloroethylene, or TCE, which is a result of Cold War-era nuclear missile maintenance east of Cheyenne.

Paul Johnston, public affairs officer for the Omaha district of the Army Corps of Engineers, said the Corps is charged by the Department of Defense to administer the FUDS (formerly used defense sites) program.

That means taking care of a range of sites, “from missile sites to old training grounds to WWI and WWII bombing ranges and old munitions storage; the whole gamut,” Johnston said.

But right now, the city is paying the $20,000 a year it takes to remove the TCE from the water before it arrives at residents’ taps.

It also paid $600,000 for the aeration basin that removes the chemical when it was first found in 1998, Jane Francis, geological supervisor at the Wyoming Department of Environmental Quality, said.

“Our first priority is safe drinking water,” Bud Spillman, manager of the water treatment division of the Cheyenne Board of Public Utilities, said in a news release. “We can remove the TCE at the treatment plant and do not allow any water contaminated with TCE to be piped to town.”

But before the water from the newly-acquired Belvoir Ranch can be sent to Cheyenne, the aeration basin at the treatment plant will need to be increased, according to a BOPU news release.

“The cost to increase capacity at the aeration basin is a cost that Cheyenne’s residents shouldn’t have to pay,” Spillman said in the release.

[...]

The Army Corps has been studying the contamination in Cheyenne for the last seven years, Francis said.

They’re making slow progress in trying to find out how long the contamination plume is, she added. It is the position of the department that there is one large plume of TCE that is a result of the chemical being used at the Atlas No. 4 missile site.

Johnston said there are two areas of contamination. One is obviously because of the work at the missile site.

The Army Corps is taking full responsibility for that site, he said, and taking steps to clean it up.

But there is a 2- to 3-mile stretch where there is no contamination, and the TCE picks up again about 10 miles from the missile site. The source of the contamination at that site isn’t clear to the Army Corps, Johnston said.

Working with the Environmental Protection Agency and BOPU, “all of us cannot find a firm link between the two contaminated areas,” he said.

That’s as of yet, anyway. In June, Johnston said the Army Corps plans to have more people out in the field doing studies to determine the source of contamination for the second plume.

If it is found that the water is also contaminated because of the missile maintenance, the Army Corps will take full responsibility and clean it up, he said.

Vapor intrusion in Dayton from Behr Dayton Thermal Products plant (OH)
by Neil Fischbein on Friday, February 22, 2008 [Permalink] [0 Comments]
Toxic TCE vapors are entering homes in Dayton. Though EPA is on the case, they've run into a few complications:
Efforts to make homes safe from contaminated groundwater fumes near the Behr Dayton Thermal Products plant, 1600 Webster St., have run into problems at as many as 10 homes.

And the effort to clean indoor air contamination at a nearby school is ongoing, authorities have said.

TCE fumes have migrated from the soil into the homes, businesses and schools, creating potentially hazardous vapors.

In homes that have dirt basement floors, those floors must be sealed for the air evacuation systems to work properly, said Mark Case, director of environmental health for Public Health Dayton & Montgomery County.
Levels of contamination in the problematic homes have reportedly dropped below 10 ppb. That's still 25 times the Ohio Department of Health's exposure limit of .4 ppb.

Clean-up plan proposed: Moses Lake and former Larson Air Force Base (WA)
by Neil Fischbein on Wednesday, February 13, 2008 [Permalink] [0 Comments]
A story in today's Columbia Basin Herald (WA) announced a Wednesday-night meeting in Moses Lake, WA where EPA was scheduled to present their clean-up plan for a massive groundwater contamination site. Sorry we posted this news so late, but it gives us the opportunity to tell you more.

The site is known as the Moses Lake Wellfield Contamination Superfund site. According to today's article, the TCE contamination has persisted (and, we assume, migrated) for about 50 or so years.

In a press release earlier this month, EPA previewed their plan:
A comprehensive cleanup plan for the trichloroethylene (TCE)-contaminated groundwater at the Moses Lake Wellfield Contamination Superfund site has been issued for public review by the U.S. Environmental Protection Agency (EPA). The site is located just north of Moses Lake and includes the Grant County Airport, the former Larson Air Force Base, and areas south of the airport.

“This cleanup plan takes steps that will protect human health and the environment and restore groundwater quality,” said Lori Cohen, EPA’s Associate Director of the Office of Environmental Cleanup.

The groundwater and soils at the site were contaminated with trichloroethylene (TCE) and other hazardous substances by operations of the former base and industrial activities associated with the aircraft industry. Approximately 1000 acres of groundwater are contaminated with TCE above health based standards and several contaminated soil waste areas are scattered throughout the site. The proposed cleanup is expected to cost about $31 million. TCE is an industrial solvent that was commonly used at this site for stripping paint from airplanes, washing airplane parts, and cleaning missile components.

The proposed cleanup plan calls for:
  • pumping out the most highly contaminated water and treating it to remove TCE;
  • cleaning up the contaminated soil areas by removing soils contaminated above safe levels;
  • restoring the groundwater to its highest beneficial use as a drinking water source; and
  • requiring local land use restrictions such as changes to local ordinances, zoning, and property easements to protect the public from contaminated groundwater and soils until cleanup work is completed.
In 1988, TCE contamination was found in three of the City of Moses Lake drinking water supply wells on the base. TCE contamination was also discovered in the Skyline Water System wells located south of the base. Since that time, EPA and the U.S. Army Corps of Engineers (Corps) have been investigating the contamination and cleanup options at Moses Lake. Between 1989 and 1993 the City fixed the three contaminated wells on the former base by deepening the wells. In 2003, the Corps constructed a replacement water supply well for the Skyline Water System. Continued testing has shown that the City and Skyline wells continue to provide reliable, clean drinking water to the community. The Corps and EPA continue to test a representative set of wells (up to 80) at the site. Based on this sampling, five homes have had whole-house filters installed at their wells to remove TCE from the water.

The safe level for TCE in drinking water is set at 5 parts per billion (ppb). The contaminated groundwater at this site contains TCE concentrations above 5 ppb and some areas contain TCE as high as 80 ppb. The primary risks for people who drink water containing TCE in excess of 5 ppb over many years are the potential to experience liver problems and an increased risk of getting cancer.
Though we haven't been able to dig through much of it, EPA has links on its website to a whole treasure trove of documents related to the Moses Lake site, including the proposed clean-up plan [PDF, 26 pp., 148K] that was presented tonight. According to EPA's website, the following people are available to answer questions about the site:

High TCE levels discovered at Buell Automatics (NY)
by Neil Fischbein on Monday, February 11, 2008 [Permalink] [0 Comments]
Over the weekend, the Rochester Democrat and Chronicle (NY) reported extremely high levels of TCE in soil and groundwater in Gates, NY:
After a four-year investigation, the DEC found high levels of trichloroethene (TCE) in soil and groundwater at Buell Automatics, 381 Buell Road. A toxic volatile organic compound used as a solvent in dry cleaning and removal of grease, trichloroethene in large amounts can cause health symptoms similar to those of alcohol intoxication, beginning with headache, dizziness, cardiac arrhythmias and liver and kidney problems. MAP

The tainted groundwater flowed 200 feet southwest, toward the Comfort Inn, 395 Buell Road, the report said. DEC officials performed a vapor intrusion analysis near and around the hotel. The site is not near a residential area.

[...]

DEC officials conducted investigations between March 2002 and September 2006 to evaluate geologic and groundwater conditions on- and off-site. The investigation included sampling and chemical soil analysis from more than 60 soil borings, 19 groundwater wells and indoor air from buildings at three adjacent properties.

The DEC testing showed TCE levels for the soil at 820 parts per million and groundwater at 15 parts per million, both much higher than standard numbers.

EPA settles with defendants re: Groveland Superfund site (MA)
by Neil Fischbein on Tuesday, January 29, 2008 [Permalink] [0 Comments]
According to EPA's recent press release:
Release date: 01/25/2008

Contact Information: David Deegan, (617) 918-1017

(Boston, Mass. - Jan. 25, 2008) - The U.S. District Court in Massachusetts on January 9 entered a settlement agreement (Consent Decree) for the 850 acre Groveland Wells Nos. 1 and 2 Superfund site in Groveland, Mass [see map]. Settling with the United States, on behalf of EPA, is Groveland Resources Corp. and Valley Manufacturing Products Co.

Under the terms of the agreement, the Settling Defendants will pay 100 percent of the Net Sale or Net Lease Proceeds in the event their property on the Site is sold or leased to reimburse the United States for costs incurred at the site. The Settling Defendants will also be required to impose certain deed restrictions or institutional controls on the Site in order to protect EPA's cleanup actions at the site.

The Groveland Wells Site is located within a residential area in the southwestern part of the Town of Groveland. Valley Manufactured Products Co. manufactured screw products as well as metal and plastic parts from 1963 until 2001. The site is contaminated primarily with trichloroethene (TCE) which was used to clean (degrease) finished parts. TCE was released into the ground from a variety of sources including, underground storage tanks, underground disposal systems and intentional dumping. The Groveland site was added to EPA's National Priority List in September 1983. EPA has been conducting cleanup actions at the site that address the contamination in the soil and groundwater.

Contamination and litigation in Rialto (CA)
by Neil Fischbein on Tuesday, January 29, 2008 [Permalink] [0 Comments]
In 1997, the Rialto-Colton Groundwater Basin, a source of drinking water to tens of thousands of San Bernardino County residents, was found to be contaminated by TCE and perchlorate. According to EPA, "the contamination has forced the closure of numerous public drinking water supply wells and caused hardships for Rialto, Colton and neighboring areas dependent on the basin for their drinking water." Ever since, the City of Rialto has attempted to treat the contaminated wells, remediate the perchlorate and TCE, and also recover costs for its efforts from a number of potentially responsible parties (PRP's).

In a 2005, when EPA granted the affected cities more than $400,000 towards the cost of clean-up, the San Bernardino Sun (CA) explained why this money was "just a drop in the bucket":
It costs more than $1 million to install perchlorate filters on a well, and about $500,000 a year for maintenance.
...
Fontana Water Co. General Manager Mike McGraw said the city spent about $3 million to set up treatment for two contaminated wells.
...
[Colton] has spent more than $4 million to date treating three wells for perchlorate, Medina said. He wouldn't rule out a rate increase.
...
Rialto is suing the Department of Defense and 42 of its contractors, as well as fireworks manufacturers, for perchlorate contamination. One defendant, B.F. Goodrich, gave $4 million to the cities and district.

Rialto has spent about $7.6 million on legal fees and cleanup. It is treating two of its wells for perchlorate contamination.
Fast forward to 2008. After spending nearly $20 million trying to "hold dozens of suspected polluters responsible," Rialto has just fired their city attorney (Bob Owens, who allegedly was quarterbacking Rialto's strategy for recovering costs from other polluters) and is facing significant uncertainty as it prepares to determine what's next.

Meanwhile, on the City of Rialto's website, in addition to tracking the latest clean-up/lawsuit news and developments, the following declaration appears:
The City will continue to provide the citizens of Rialto with clean, safe, and affordable drinking water. It will also pursue parties that are responsible for the perchlorate pollution to pay for the clean up of the Rialto-Colton Groundwater Basin. It will repay Rialto’s ratepayers for the costs incurred in forcing the polluters to clean it up.

TCE detected in residential wells near CTS site; Meeting Thursday night (Skyland, N.C.)
by Neil Fischbein on Tuesday, January 29, 2008 [Permalink] [0 Comments]
EPA and North Carolina Department of Environment and Natural Resources (NCDENR) discovered TCE approximately 3/4 mile to the northeast of the contamination at the former CTS plant on Mills Gap Road in Skyland, N.C. According to the official press release:
Of the 66 wells sampled, one active well showed the presence of Trichloroethylene (TCE) in excess of EPA's Maximum Contaminant Level (MCL), the level established to be protective of human health. The well is located approximately three-fourths of a mile northeast of the site. The sampling also detected trace quantities of cis-1,2-Dichlorethylene, a breakdown product of TCE, below the MCL. EPA provided bottled water to the affected residence and re-tested the well in question. The second set of sampling confirmed the presence of TCE at the level indicated by the original testing.

NCDENR also identified all active residential wells in the immediate area of the contaminated well. On January 8, 2008, NCDENR tested eight wells not previously tested during the November and December sampling events. Of the eight wells, one well, located immediately east of the contaminated well, contained TCE below the MCL. No contaminants were detected in the other five wells.
The Asheville Citizen-Times (NC) adds:
The latest round of testing came in response to state testing in August that found levels of the industrial solvent trichloroethylene, or TCE, in areas around the former plant had not significantly decreased as a result of cleanup efforts at the site, which removed more than 1,600 pounds of the solvent from soil underneath the building in a little over a year of operation.
On the Citizen-Times' comments page, Representative Charles C. Thomas calls the developments here "a true tragedy." Not only does he claim this represents "a dereliction of duty on the part of state and federal government of the highest order," but he firmly states, "Those who are responsible must be held to account."

Speaking of being held to account, according to a previous press release, EPA and NCDENR also conducted some sort of vapor intrusion study in December. If they are prepared to answer questions about it tomorrow night (as they say here), why no mention of the vapor intrusion study results in the press release or news?

REMINDER: EPA will hold a public meeting to discuss the activities at the Mills Gap Groundwater Contamination site on Thursday, January 31, 2008 at 6:30 p.m. at the Skyland Fire Department (9 Miller Road, Asheville, N.C.). EPA, NCDENR, Buncombe County Health Center,and ATSDR will all be present to answer questions and explain que paso.

Ithaca TCE levels 'virtually unheard of'; NY DEC to retest (NY)
by Neil Fischbein on Friday, January 25, 2008 [Permalink] [0 Comments]
At Thursday's meeting, NYS DEC reported findings of "unusually high" levels of TCE in the ambient air outside South Hill homes in Ithaca:
Emerson found levels of trichloroethylene, or TCE, at levels ranging from 1.2 to 29.5 micrograms per cubic meter in ambient air outside homes downhill and north of its factory on South Hill.

Morse Chain, the site's previous owners, used degreasing solvents containing volatile organic compounds like TCE until the late '70s.

Of 12 locations tested, eight showed unusually high results, said Karen Cahill, regional engineer with the DEC. Of the 12, four were from areas in the Phase 5 investigation area, near the police station, and eight were near homes with mitigation systems installed.

John Criscitello lives at 401 S. Cayuga St. in one of those homes. He has a mitigation system in his house to pull TCE out from under his basement sub-slab and send it into the outside air, where it is supposed to dissipate.

The ambient air reading outside his home was 25 micrograms per cubic meter. The indoor air measurement that the state Department of Health considers unsafe is 5 micrograms per cubic meter. Emerson mitigates homes with indoor air readings at 0.8.

Levels this high in outside air are virtually unheard of.
According to this report in the Ithaca Journal (NY), DEC's immediate next step is to retest "to see if those numbers are real or not."

ABC News: Casualties of War and TCE
by Neil Fischbein on Friday, January 25, 2008 [Permalink] [0 Comments]
Chris Francescani of ABC News's tough-sounding Law and Justice Unit reported Thursday on the FUDS clean-up project. FUDS stands for Formerly Used Military Defense Sites:
In 1986, when the Department of Defense established the FUDS program, the Army was charged with going back through all available military records to determine when and where the D.O.D. caused contamination, via unexploded munitions, or chemical contamination through the use of compounds now known to be carcinogens, such as trichloroethylene, known as TCE, which was widely used to degrease fighter jets and missiles during the Cold War.

More than 9,000 sites were identified, according to Addison D. 'Tad' Davis, the Army's deputy assistant secretary for environment, safety and occupational health. He said that at least 2,700 sites around the country have been identified as needing a cleanup...
While much of the article focuses on the impact of unexploded munitions, a portion of it addresses TCE:
Another problem the military faces is detecting chemical contamination. Sites that were tested and rendered safe 20 years ago are being revisited, in light of more advanced scientific information.

[...]

"[I]n the past 10 to 15 years, TCE was found to be a carcinogen, so TCE is now very much a priority,'' [Davis] said.
(Yeah, yeah we know. TCE has been a known poison for decades, but this is not the time to quibble with the man's sense of history. He agrees its remediation is a priority, that's what matters here.)

How did all this happen? So glad you asked:
"How it happened is very simple," said Candice [a.k.a. "Candy"] Walters, a spokeswoman for the United States Army Corps of Engineers, which has been tasked by the Department of Defense with surveying and cleaning up the sites.

"Since the American Revolution on forward, the U.S. military has trained it's troops to fights wars. And part of that training is training with live ammunition,'' which, Walters said, included firing ranges, aerial bombing, and even cannon practice.

The military bought, rented or leased thousands of stateside properties over the years, she added.

"At the end of the wars, there wasn't a need to have the [military training] installations anymore, so they closed them down and either gave them back to the property owner, or back to the state or county.

"They did what was environmentally acceptable at the time, which was, they dug a patch and buried them,'' Walters said. "They'd sweep up what they could see on the ground, and collect and dispose of them underground.

"What they tried to do when they gave back the land was to say that, in some cases, there could be unexploded ordnances underground. But much of this was farmland, forests, places where no one ever thought people would ever build a housing project there."
We have been saying for some time that states must follow in New York's and New Jersey's footsteps and re-open old, previously-thought-closed site investigations to account for landscape-changing knowledge (like our evolving understanding of vapor intrusion risk). Nice to see the military at least taking steps in this direction.

Motorola hired Arizona American Water Co. (AZ)
by Neil Fischbein on Friday, January 25, 2008 [Permalink] [0 Comments]
The East Valley Tribune (AZ) reveals:
The investigation into last week’s drinking water scare in parts of Scottsdale and Paradise Valley has expanded to include Motorola, potentially leaving the electronics giant open to federal fines, environmental officials said Wednesday.

Meanwhile, Arizona American Water Co. — the private utility with whom Motorola contracts to treat groundwater pumped from a local Superfund site — is considering what to do with up to a half-million gallons of potentially contaminated water in a reservoir underneath its treatment plant.

[...]

Motorola is one of four companies charged with dumping TCE into Scottsdale’s groundwater supply beginning in the 1950s. Motorola hired Arizona American to pump and treat that groundwater, and could be held responsible for mishaps, Takata said.

There's a decades-old plume of TCE and PCE in Chico, CA that migrated nearly two-miles from its source and has contaminated residents' well water for years:
The Skyway plume was discovered when area residents asked for wells to be tested because they were concerned a nearby tank farm might be leaking petroleum-based contaminants into their groundwater. Instead, unacceptable levels of chlorinated solvents were found and traced back to an operation that manufactured aluminum shower enclosures on Speedway Avenue from 1962 until 1976.

Preliminary tests revealed the contamination extends about two miles from its origin, flowing under Skyway and Cessna avenues and ending along Hegan Avenue near the Chico State University farm. [see map]
Just this week, ABB, the company being "held responsible for clean-up costs," agreed to pay for 63 residential hook-ups to the water system run by California Water Service Company (a.k.a. Cal Water). Meanwhile, the investigation into the overall size of the plume continues.

UNC set to clean up its own chemical waste (NC)
by Neil Fischbein on Monday, January 21, 2008 [Permalink] [0 Comments]
Years ago, University of North Carolina (UNC) Hospitals and Department of Chemistry disposed of benzene, chloroform, methylene chloride and trichloroethylene by burying them underground in containers near Horace Williams Airport. Over time the contaminants leaked into the surrounding soil and groundwater. Now, UNC is taking steps to clean things up.
The University first committed to cleaning the area in 2003, when it signed a voluntary agreement with the N.C. Department of Environment and Natural Resources.

The cleanup is expected to cost about $4.5 million and should be finished by the end of the summer. It will not affect the airport's operation, said Larry Daw, an environmental specialist for UNC's Department of Environment, Health and Safety.

[...]

UNC used the site from 1973 to 1979 to dispose of lab chemical waste generated by the campus and what was then N.C. Memorial Hospital. Although it has since been outlawed, burying waste was permissible under state laws at the time.

"It was a common practice in those days to dispose of waste in that manner," Daw said. "After that time period, there were some new laws coming into effect."

Jan 31 meeting re: Mill’s Gap Groundwater Contamination site in Skyland (NC)
by Neil Fischbein on Sunday, January 20, 2008 [Permalink] [0 Comments]
From the EPA newsroom:
EPA to Hold Public Meeting for Mill’s Gap Groundwater Contamination Site in Skyland, N.C.

Release date: 01/14/2008

Contact Information: Dawn Harris-Young, (404) 562-8421, harris-young.dawn@epa.gov

(Atlanta, Ga. – Jan. 14, 2008) The U.S. Environmental Protection Agency (EPA) will hold a public meeting on Thursday, January 31, 2008 regarding current activities at the Mill’s Gap Groundwater Contamination site in Skyland, N.C. EPA, North Carolina Department of Environment and Natural Resources (NCDENR), Agency for Toxic Substances and Disease Registry, and Buncombe County Health Center officials will provide information and answer questions about recent sampling related to the site and an enforcement update.

The public meeting will begin at 6:30 p.m. at the Skyland Fire Department, 9 Miller Road, Skyland, N.C. Community members interested in obtaining additional information are encouraged to contact Sherryl A. Carbonaro, EPA Community Involvement Coordinator, at (678) 575-7355.

The site is located off Mills Gap Road, approximately one mile east of Skyland, in Buncombe County, N.C. and consists of approximately nine acres of maintained grounds containing a large, single-story building. In 1952, IRC, Inc. (IRC) bought the land and constructed the building which was used for its electroplating operations. In 1959, IRC sold the property to CTS, Inc (CTS). From 1959 to 1986, CTS operated an electroplating facility at the site. In 1987, Mills Gap Road Associates (MGRA) purchased the site and is the current owner. Environmental sampling has indicated the subsurface beneath the former plant is contaminated with the chemical compound trichloroethylene (a.k.a. trichloroethene or TCE) as well as petroleum products. In 1999 TCE was discovered in nearby springs and one residential drinking water well. This past December, EPA and DENR commenced more extensive sampling that included expanded residential well sampling and vapor intrusion sampling at homes in close proximity to the site.

ATTENTION: A media availability session will be held at the Skyland Fire Department, 9 Miller Road in Skyland, N.C. from 5:00 p.m. to 6:00 p.m. on Thursday, January 31, 2008. Officials will be available to answer media questions concerning current activities underway at the site. This arrangement will allow for the public to use the entire public meeting to get information and have their questions answered.

AVX to court: Myrtle Beach land owners should pay (SC)
by Neil Fischbein on Sunday, January 20, 2008 [Permalink] [0 Comments]
File this under questionable legal tactics: According to The Sun News (Myrtle Beach, SC), AVX filed recent court documents seeking to stick residents and other property owners, some of whom have sued AVX, with part of the tab from AVX's TCE investigation and clean-up:
The electronics manufacturer filed a proposed amended complaint last week in federal court that would make those property owners subject to federal laws that require shared liability for environmental contamination.

That means property owners living near AVX could be forced to pay the manufacturer a prorated share of whatever amount AVX spends for "investigations, containment, removal or mitigation of the contamination at the properties," according to the proposed complaint.

That amount could be measured in the millions of dollars.

AVX also wants property owners to pay "interest at the maximum rate allowable by law" for any amount they might owe to the manufacturer.

A judge has not made a ruling on the proposed complaint.

Gene Connell, a lawyer representing property owners near AVX's headquarters at 801 17th Ave. S., said the proposal is an unconscionable scare tactic.

"It's audacious that AVX would try to blame its pollution on the poor people who've worked all their lives for their homes," Connell said. "These are innocent landowners."

[...]

AVX, in its proposed complaint, wants a federal judge to rule that contamination has not damaged any property near the manufacturer's headquarters because the TCE eventually can be removed from the groundwater.

[...]

AVX also wants a judge to rule that property owners are entitled to no compensation for any possible damage to their land or property values resulting from the contamination.
Though we're reluctant to play armchair legal quarterback without seeing the court-filed documents (yeah, we'll do it anyway), we'd say the first part of the complaint, the move to pin costs on property-owners, may be designed to discourage public participation in litigation against AVX (almost as if to say, "Hold us accountable and you'll literally pay for it.")

The latter two issues, that no property was damaged and that owners aren't entitled to compensation for certain damages, sound to us like they depend on questions of fact that a trial must ultimately decide. But we are not attorneys nor familiar with all the applicable facts or laws in this case, so really, what do we know?

New TCE detected in Runkle Canyon near Rocketdyne/Santa Susana Field Laboratory (CA)
by Neil Fischbein on Saturday, January 19, 2008 [Permalink] [0 Comments]
Investigative journalist Michael Collins alerted us to this news about newly disclosed TCE detects in Runkle Canyon near where KB Homes has plans to build:
KB Homes had hoped to build 461 residences in the 1,595-acre canyon, but those plans have been delayed since the summer of 2006 when Southwick and a cadre of residents who call themselves the "Radiation Rangers" (See: "Dirty Business," Nov. 1, 2007) questioned the safety of the project.

[…]

The Reporter has obtained a December 2007 study of offsite pollution around SSFL prepared by an Arcadia-based environmental engineering firm MWH for Boeing, NASA and the Department of Energy which shows that TCE has been detected in approximately 10 percent of several dozen groundwater samples collected on Runkle Canyon property.

[…]

Around 1.73 million gallons of TCE were used at [Santa Susana Field Laboratory] as a solvent to hose down rocket engines, as the Reporter first revealed during its investigation of the Runkle Canyon-adjacent Ahmanson Ranch development. That project tanked over toxic troubles in 2003 before becoming state park land (See: "Air Apparent," Feb.13, 2003). Approximately 530,000 gallons of the carcinogen, which is a volatile organic compound, have seeped into the area's groundwater. With the current rate of remediating TCE being less than 10 gallons a year at SSFL, it will take more than 50,000 years to clean up.

More on new tests in Endicott/Union (NY)
by Neil Fischbein on Friday, January 18, 2008 [Permalink] [0 Comments]
From today's Press & Sun-Bulletin (Binghamton, NY):
State environmental officials are seeking permission from property owners to begin testing in and under about 80 homes south of June Street in February and March, as the next phase of a TCE probe begins in an area encompassing about 400 properties.

Lori O'Connell, a spokeswoman for the state Department of Environmental Conservation, outlined more details this week about the scope of the investigation, which will include an industrial site on the north end of Badger Avenue and its affect on the surrounding neighborhood.

The area extends from West Endicott into the Town of Union.

[...]

Officials have scheduled a public meeting at 7 p.m. Jan. 23 at Union-Endicott High School to outline plans and answer questions about the investigation around Badger Avenue.

Union Pacific Railway suspected in residential contamination in Eugene (OR)
by Neil Fischbein on Friday, January 18, 2008 [Permalink] [0 Comments]
KVAL Channel 13, a CBS station in Eugene, OR, has the following story posted on their website:
From 2004 to 2006, air samples were taken from homes in the Trainsong area. The results showed crawl-spaces filled with high amounts of cancer-causing agents from tainted groundwater.

Precautionary measures were taken for those homeowners. Now comes the task of determining if those measures worked.

"I didn't know there was a problem until last year," said Trainsong resident, Glenda Carroll.

Carroll lived in the Trainsong neighborhood with her husband for almost twenty years. She says he died last last January from kidney failure.

"They say kidney failure is one of the things that this causes. I can not tell you how many cats I've had that have died of kidney failure in this house," said Carroll.

Carroll lives in one of ten homes being tested for the presence of the chemicals TCE and PCE.
Officials reportedly believe the contamination came from Union Pacific Railway maintenance that was conducted across the street from the affected area. For the rest of the story, see here.

Midland County site may be placed on Superfund; Polluters being sought (TX)
by Neil Fischbein on Thursday, January 17, 2008 [Permalink] [0 Comments]
According to this report from Midland Reporter-Telegram (TX), the Midessa Ground Water Plume may soon be added to the Superfund list:
The U.S. Environmental Protection Agency is looking for a responsible party or parties in west Midland County groundwater contamination and will make them pay for the cleanup if they are found, an EPA official says.

Remedial Project Manager Vince Malott of Dallas said the public comment period ended in November and his agency may put the project on its national "Superfund" list in late March or April.

"We have an enforcement officer working with the Texas Commission on Environmental Quality on potential leads to where the (contamination) source originated," Malott said on Monday. "We're still searching for the likely source and don't have a lead we can announce.

"Once we get to that point, we will send the responsible party a notice and give them an opportunity to reply. We're avoiding using taxpayers' dollars if we can find viable financially responsible partners."

[...]

When the situation was first announced in September, [well] water was reported to contain MCLs of dichloroethene, trichloroethene, dichlorothane and tetrachloroethene -- all solvents that possibly had been used for degreasing or breakdown products disposed of unsafely.

TCEQ said the water supplies of 168 people were contaminated, including residents of Midessa Oilpatch RV Park and private wells just east of the Midland-Ector County line.
Read the full story here.

Note: Though EPA's website is light on details, it tell us that PCE was detected in wells at concentrations as high as 1200ppb. Like TCE, the federal action level for PCE in water wells is 5ppb. As though this wasn't bad enough, there were 3 other toxins found in these wells, including TCE (at what levels, the EPA does not say). Perhaps more revealing, however, is EPA's note that:
There is no muncipal city water supply available to this rural sector of Midland county currently, or for the foreseable future. TCEQ has not yet defined the outer boundary of the plume.
Makes us wonder what the affected residents are drinking, bathing, and cooking with. Then there's the question of how safe their air is. With significantly elevated levels of toxins running underground and seeping into wells, surely vapor intrusion must be a concern. What are the chances residents have been warned?

Purdue University using trees to breakdown TCE
by Neil Fischbein on Monday, January 14, 2008 [Permalink] [0 Comments]
Can trees help us remediate TCE? This story comes from today's Journal and Courier (Lafayette, IN):
Purdue helping to remove pollutants using poplars
January 14, 2008

The news

Purdue University researchers and Chrysler LLC are collaborating on a project using modified poplar trees to eliminate pollutants from a former oil-storage facility near Kokomo.

In laboratory experiments, the trees have been shown to be capable of absorbing trichloroethylene, or TCE, and other pollutants. The pollutants are then turned into harmless byproducts.

The study

Richard Meilan, a Purdue associate professor of forestry and natural resources with Purdue's Hardwood Tree Improvement and Regeneration Center and the Center for Tree Genetics, co-authored a study published last fall that showed poplar cuttings could remove 90 percent of TCE from a solution in one week.

The trees are called transgenic poplars because they have an inserted gene that aids the breakdown of TCE and other environmental pollutants.

TCE is the most common groundwater pollutant on Superfund sites and causes various human health problems when in the water or air.

The study was published in Proceedings of the National Academy of Sciences.

The process

Meilan believes the poplars will be able to absorb the TCE from the site with their roots. Peter's Pond was contaminated by oil stored there in the 1960s. The oil is now within 10 feet of the surface, easily reachable by poplar roots.

There is concern by some that the inserted genes could escape the trees and invade other natural tree populations, but Meilan said he's trying to make sure that isn't the case by removing the trees before they reach sexual maturity.

"It is legitimate to be concerned about transgenic plants, but we are taking comprehensive steps to ensure that our transgenes don't escape into the environment," Meilan said.

A peek inside the Toxic Chemical Exposure Reduction Act
by Neil Fischbein on Friday, August 3, 2007 [Permalink] [0 Comments]
Yesterday brought us the introduction of the Toxic Chemical Exposure Reduction Act by Senators Clinton, Dole, Boxer, Lautenberg, and Kerry. Here are the main provisions of the 15-page bill:

The Act establishes that the EPA must:
  • Publish a health advisory for trichloroethylene that fully protects, with an adequate margin for safety, the health of susceptible populations;

  • Propose and impose a national primary drinking water standard that protects sensitive populations and is set as close to the maximum contaminant level goal for trichloroethylene as is feasible;

  • Enforce the requirement that all qualified drinking water monitoring systems accommodate the new drinking water standards proposed and imposed above;

  • Require monitoring of water supplies currently in the path or proximity of migrating TCE;

  • Require that Consumer Confidence Reports include the known health risks of TCE exposure and detail any TCE discovered in the monitored water supplies.
With respect to Vapor Intrusion, the EPA must: --

We have some thoughts to share on several of these provisions, and will be back shortly to do so.

Meantime, we have emailed representatives for Senator Dodd and Senator Lieberman, both from Connecticut, and have asked if the Senators will be able to support the TCE Reduction Act. So far...no reply. But it's only been a day.

We'll keep you posted.
