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.

The superfund site is situated approximately 1.5 mi (2.4 km) south of the UCD campus in Solano County, California.Research sponsored by the U.S. Department of Energy at the site commenced in the 1950s, with full-scale operations beginning in 1958, focusing on chronic, low-level exposure of skeletal structures to beta particle irradiation from bone-seeking radionuclides, strontium-90 and Radium ...
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 ]
Average hexavalent chromium levels in Hinkley were recorded as 1.19 parts-per-billion (ppb), with an estimated peak of 20 ppb. Based on the PG&E Background Study, the PG&E Topock Compressor Station averaged 7.8 ppb and peaked at 31.8 ppb. [33] The proposed California health goal for hexavalent chromium was 0.02 ppb in 2011.

This is a list of Superfund sites in Missouri designated under the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) environmental law. The CERCLA federal law of 1980 authorized the United States Environmental Protection Agency (EPA) to create a list of polluted locations requiring a long-term response to clean up hazardous material contaminations.

An example of this chemical causing adverse health issues is through a well-known hexavalent chromium (chromium 6) pollution event in Hinkley, California. Groundwater contamination in Hinkley was caused by water containing hexavalent chromium being dumped on the ground by Pacific Gas and Electric (PG&E) from 1952 to 1966. PG&E used this ...
The woes of Greg Focker aren't over just yet. Ben Stiller, Robert De Niro, Teri Polo, and Blythe Danner are in early talks to return for a fourth Meet the Parents movie, nearly 15 years after they ...
The NPL guides the EPA in "determining which sites warrant further investigation" for environmental remediation. [2] As of May 1, 2010, there were 48 Superfund sites on the National Priorities List in Washington. [2] Seventeen others have been cleaned up and removed from the list; no sites are currently proposed for addition. [2]
