Hexavalent chromium pollution in Greece is associated with industrial waste. By using the GFAAS for total chromium, diphenylcarbazide-Cr(VI) complex colorimetric method for hexavalent chromium, and flame- AAS and ICP-MS for other toxic elements, their concentrations were investigated in several groundwater samples.
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 lawsuit ...
Exposure to hexavalent chromium can cause irritation and problems in the respiratory tract, stomach, and small intestine. It is linked to several cancers, such as lung cancer, oral cancer, and intestinal cancer. [11] During floods, the chromium contaminated groundwater would flood into local Garfield residences and businesses.
California has set a limit for the toxic heavy metal hexavalent chromium in drinking water. Advocates have called for a stricter limit, warning of health risks.
In June 2009, Brockovich began investigating a case of contaminated water in Midland, Texas. [26] "Significant amounts" of hexavalent chromium were found in the water of more than 40 homes in the area, some of which have now been fitted with state-monitored filters on their water supply. [26]
Soil contamination by metals including chromium, copper and lead and groundwater and surface water contamination by hexavalent chromium from former tool manufacturing. Groundwater contamination has affected the Memphis Aquifer and two Collierville municipal wells have been taken out of service as a result. [49] [50]
Soils contaminated by radiological and chemical waste from plutonium manufacture for the Manhattan Project and subsequent activities. Groundwater contaminated by strontium-90, carbon-14, tritium and hexavalent chromium and discharges into the Columbia River, which is the water supply for over 170,000 people. [33] June 24, 1988: April 10, 1989 –
From 1952, Hinkley has had its groundwater contaminated with hexavalent chromium by a compressor station for natural gas transmission pipelines. Residents of Hinkley eventually filed a class action lawsuit against Pacific Gas and Electric Company (PG&E).
