From the LA Times : Cancer Stalks a 'Toxic Triangle'
Scientists disagree about the risks of TCE. But residents near a former air base are dead certain.

March 30, 2006SAN ANTONIO — On nearly every block surrounding the former Kelly Air Force Base, small purple crosses sprout from front lawns, marking the homes where cancer has struck.
The residents call their neighborhood the "toxic triangle," alleging that the Air Force poisoned it with an industrial solvent, trichloroethylene, or TCE. It was casually dumped at the base for decades and spread for miles through a shallow aquifer under 22,000 nearby houses.
Texas health authorities have found elevated rates of liver cancer among residents, as well as higher-than-normal rates of birth defects. Though state health officials say it is impossible to prove that TCE causes the sickness here, this blue-collar community has little doubt about the connection.
"We are dying day by day," said Robert Alvarado Sr., who has lived in a small clapboard home for 36 years that sits about 14 feet over the TCE plume. "I have kidney failure, my wife has thyroid cancer, my neighbor just died of breast cancer."What's happening in this neighborhood of modest low-slung homes, crisscrossed by railroad tracks and dominated by aircraft hangars on the horizon, has been playing out for years at other cities that are home to military bases, industrial plants, nuclear weapons laboratories and NASA centers.
Hundreds of communities with major TCE contamination have waited more than a decade for scientists to explain the cancer risks created by exposure to TCE. The clear solvent used to take grease off metal parts is officially branded as a probable carcinogen by half a dozen state, federal and international agencies. It is most often linked to liver and kidney cancer, as well as birth defects and childhood leukemia.
