The Standard-Examiner (Ogden, UT) reports:

State environmental officials refuse to sign off on a high-adventure recreation center for the downtown mall site until the city has more soil and groundwater tests completed.

Meanwhile, Ogden Mayor Matthew Godfrey said the city plans to seek a special designation that would make the 20-acre parcel eligible for federal funds to pay for additional environmental tests.

[...]

To avoid similar delays when it comes to other projects at the mall site — where officials hope the rec center will be a catalyst for retail and residential development — Godfrey said the city will pursue a "brownfield" designation.

Such a designation makes contaminated land eligible for federal funding that would allow DEQ to conduct environmental tests and research the land's historic use, said Brent Everett, an environmental program manager for DEQ.

Then, any necessary cleanup can be paid for by previous property owners, developers or other parties.

Presumably clearing up questions about whether the contaminants of concer included TCE (Trichloroethylene) or PCE (Tetrachloroethylene), the paper continues:

[T]he city's second round of soil and groundwater tests showed petroleum concentrations as high as 520 parts per million. The regulatory limit is 10 parts per million. Concentrations of tetrachloroethylene, a solvent used in dry-cleaning and metal degreasing, were as high as 13 parts per billion, more than twice the limit.
