EPA launches cleanup efforts of thyroid disrupting chemicals in California water supply

This week, the U.S. Environmental Protection Agency (EPA) announced that it will build pumps and treatment systems to clean contaminated groundwater from the Rialto-Colton basin in California, and deliver it to homes and businesses. The cleanup, is an effort to remove toxic chemicals which have been linked to thyroid problems and cancer.

The Press-Enterprise reports that the initiative, which could cost as much as $18 million, focuses on pollution from the B.F. Goodrich Superfund site. The 160-acre industrial park was a dumping ground for toxic chemicals for decades.

Perchlorate, an ingredient in fireworks and rocket fuel, and trichloroethylene (TCE), a solvent, seeped into groundwater and has traveled at least three miles.



The contaminants - which have been known to cause thyroid problems and cancer - forced closure of numerous wells serving Rialto, Colton and Fontana and the installation of expensive treatment equipment. State officials are studying possible health effects from the contamination.



Rialto homeowner Dinah Watson told the news source that many of her neighbors have had cancer and thyroid problems.

According to the National Cancer Institute, there are 19,500 thyroid cancer diagnoses in the U.S. annually.
