State sets new limits for 1,2,3-TCPBy Shaina Brown |
On Tuesday, July 18, the State Water Resources Control Board (SWRCB) set new limits for 1,2,3-TCP (Trichloropropane) in drinking water. 1,2,3-TCP is used primarily as a degreasing solvent and pesticide ingredient and is commonly found in ground water supplies throughout the State. Currently, there is no federal MCL for 1,2,3-TCP. The Board unanimously voted to implement the maximum contaminant level (MCL) to 5 parts per trillion (ppt), effective October 1, 2017. CMTA’s President, Dorothy Rothrock, made public comments to highlight the agency’s responsibility in considering both technological and economic feasibility when establishing drinking water standards. CMTA, along with the American Chemistry Council, also provided written comments in April which can be accessed here. |
