Rep. Edward Markey (D-MA) reintroduced a bill on February 8 that would require EPA to test additional chemicals that may be found in drinking water for potential effects on the endocrine system. The proposed legislation, titled the Endocrine Disruptor Screening Enhancement Act of 2011 (H.R. 5210), would amend the Safe Drinking Water Act to broaden EPA's Endocrine Disruptor Screening Program, established in 1996 to test chemicals for their potential to affect the hormonal system, to include additional non-pesticide chemicals. The bill would require EPA to draft a plan and timetable for identifying substances to be tested, keep up with technological advancements to see if testing protocols should be revised, and consider methods that reduce the need for animal testing and speed up the testing process. The legislation also would allow EPA to fast-track testing of chemicals that are found in drinking water, are exposed to large populations, or are suspected to be or have structural similarities to endocrine disruptors. It also would allow the public to petition EPA to test or fast-track certain chemicals. Markey originally introduced the bill in May 2010. It also was included in the Assistance, Quality, and Affordability Act, which passed the House in July 2010, but the bill then died in the Senate.
