The other day I received a call from a 58-year-old San Antonio man who worked at Kelly AFB from 1983 to 1999. He said he recently had a cancerous kidney removed, and he wondered what I could tell him about Kelly workers' exposure to carcinogens that cause kidney cancer.

...

A search of the Express-News archives turned up a dozen columns in which Kelly contaminants and potential kidney problems were discussed.

The first reference to Kelly contaminants and kidney cancer appeared in a March 22, 1998, column in which I reported that extraordinarily high levels of two volatile organic compounds — perchloroethylene (PCE) and trichloroethylene (TCE) — had been found in groundwater near Kelly.

For decades, TCE and PCE were used as degreasers at the base.

...

Last fall, in a summary of Kelly findings, federal researchers noted:

1. During 1990-1994, liver, kidney and lung cancer incidence rates in neighborhoods around Kelly were higher than incidence rates found in demographically similar neighborhoods in Texas.

2. Those cancers "could have been the result of past exposures" to Kelly contaminants.

It seems reasonable to conclude that the same might be said about the cancers of longtime Kelly workers.
