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. 

Thank you,
