They suffer many physical ailments, including bloody noses, various intestinal ailments, bad backs, rotten teeth and tumors. In 1952, PG&E built a pumping station on 20 acres near town as part of its enormous gas-transmission system. The station pumped natural gas through an artery of pipes stretching from the Texas Panhandle to the San Francisco Bay Area; the system served PG&E customers in much of the state’s Central Valley.
The company used the chromium to prevent rust from corroding its water-cooling system. The chemical runoff was disposed of in unlined wastewater ponds. (After 1966, the utility lined its ponds.) In 1987, during what the company claims was a routine check, PG&E found that its chromium had leaked into the water supply. In December 1987 it reported its findings to the California Regional Water Quality Control Board, as required. The board ordered the utility to clean up the pollution.
In the early 1990s PG&E undertook a $12.5 million cleanup effort, approaching the owners of three farms and 10 houses in the area and offering to buy their properties.
