This week, California regulators took an important step toward protecting California communities from a highly toxic drinking water contaminant found across the state. At its first public workshop on the pesticide byproduct 1,2,3-Trichloropropane (TCP), State Water Board staff shared a preliminary proposal to set the TCP drinking water standard at 5 parts per trillion, which is the most health-protective standard. Setting the standard at this level would help protect the lives of hundreds of thousands of Californians who currently drink water contaminated by TCP.
TAKE ACTION by telling the State Water Board you support their preliminary recommendation of the most health protective drinking water standard for TCP -- 5 parts per trillion!
Dear State Water Resources Control Board members,
1,2,3-TCP is a known human carcinogen found in groundwater throughout California, but no drinking water standard has been established yet. I urge you to prioritize community health by adopting the preliminary recommendation to set the Maximum Contaminant Level (MCL) at 5 parts per trillion as soon as possible.
