Pacific Gas and Electric Litigation
The case alleged contamination of drinking water with hexavalent chromium, also known as chromium (VI), in the southern California town of Hinkley. At the center of the case was a facility called the Hinkley Compressor Station, part of a natural gas pipeline connecting to the San Francisco Bay Area and constructed in 1952. Between 1952 and 1966, PG&E used hexavalent chromium to fight corrosion in the cooling tower. The wastewater dissolved the hexavalent chromium from the cooling towers and was discharged to unlined ponds at the site. Some of the wastewater percolated into the groundwater, affecting an area near the plant approximately 2 by 1 miles (3.2 by 1.6 km). The case was settled in 1996 for US$333 million, the largest settlement ever paid in a direct action lawsuit in US history. Brockovich's law firm received 133.6 million dollars of this settlement, and Brockovich herself received a two million dollar bonus from the action.
A study released in 2010 by the California Cancer Registry showed that cancer rates in Hinkley "remained unremarkable from 1988 to 2008." An epidemiologist involved in the study said that "the 196 cases of cancer reported during the most recent survey of 1996 through 2008 were less than what he would expect based on demographics and the regional rate of cancer."
Average Cr-6 levels in Hinkley were recorded as 1.19ppb with a peak of 3.09ppb. The PG&E Topock Compressor Station averaged 7.8ppb and peaks at 31.8ppb based on the PG&E Background Study. California's Public Health Goal (PHG), circa 2011, for hexavalent chromium is 0.02ppb.

Famous quotes containing the words pacific, gas and/or electric:
“We, the lineal representatives of the successful enactors of one scene of slaughter after another, must, whatever more pacific virtues we may also possess, still carry about with us, ready at any moment to burst into flame, the smoldering and sinister traits of character by means of which they lived through so many massacres, harming others, but themselves unharmed.”
—William James (1842–1910)
“Shielded, what sorts of life are stirring yet:
Legs lagged like drains, slippers soft as fungus,
The gas and grate, the old cold sour grey bed.”
—Philip Larkin (1922–1986)
“Flabby, bald, lobotomized,
he drifted in a sheepish calm,
where no agonizing reappraisal
jarred his concentration of the electric chair—
hanging like an oasis in his air
of lost connections. . . .”
—Robert Lowell (1917–1977)
