[1] [2] PG&E used chromium 6, or hexavalent chromium (a cheap and efficient rust suppressor), in its compressor station for natural-gas transmission pipelines. [1] [3] Hexavalent-chromium compounds are genotoxic carcinogens. In 1993, legal clerk Erin Brockovich began an investigation into the health impacts of the contamination. A class-action ...
There were an estimated 700 properties above or near the chromium groundwater contamination. The EPA found that 14 out of the 512 investigated basements had hexavalent chromium levels above acceptable; the EPA removed the chromium and installed systems to prevent further contamination in thirteen out of the fourteen basements.

Hexavalent chromium (chromium(VI), Cr(VI), chromium 6) is any chemical compound that contains the element chromium in the +6 oxidation state (thus hexavalent). [1] It has been identified as carcinogenic, which is of concern since approximately 136,000 tonnes (150,000 tons) of hexavalent chromium were produced in 1985. [ 2 ]
Chromate anions (CrO 2− 4) and dichromate (Cr 2 O 7 2−) anions are the principal ions at this oxidation state. They exist at an equilibrium, determined by pH: 2 [CrO 4] 2− + 2 H + ⇌ [Cr 2 O 7] 2− + H 2 O. Chromium(VI) oxyhalides are known also and include chromyl fluoride (CrO 2 F 2) and chromyl chloride (CrO 2 Cl 2). [6]
Masry & Vititoe, the law firm for which Brockovich was a legal clerk, received $133.6 million ($273.4 million in 2024) of that settlement, and Brockovich received $2.5 million as part of her fee. [13] A study released in 2010 by the California Cancer Registry suggested that cancer rates in Hinkley "remained unremarkable from 1988 to 2008". [14]
