1,2,3-TCP (1,2,3-trichloropropane) is a toxic chemical contaminating groundwater in cities and small communities across California. TCP was deemed a carcinogen by the State of California in 1992 - more than 20 years ago! - but TCP has gone unregulated and untreated in hundreds of drinking water sources across the state.
After extensive work and pressure from Community Water Center, Clean Water Action, and our partners across the state, the State Water Board is poised to set the legal limit for 1,2,3-TCP in drinking water.
The State Water Board’s draft regulations are now open for public comment, and I’ve got great news: the standard they’ve officially proposed is the most health-protective level -- 5 parts per trillion! That’s exactly what we asked for! But there’s still a strong chance the polluters will try to roll back this health-protective limit, so we need your support.
The public comment period is THE critical time for Californians like you to participate and tell the Board to fully adopt their proposed 5 part per trillion MCL.
To ensure our communities are protected from this cancer-causing pesticide ingredient, you can:
1. Submit a comment letter to the State Water Board, or to have an even greater impact, encourage your local government bodies and community organizations (your city, local water system, school, or elected officials) to submit letters too!
2. Sign our petition below!
3. Come up to Sacramento for the public hearing on April 19th to voice your support for safe, affordable water! We will be coordinating rides for residents who want to travel up to Sacramento to participate in the hearing.
Follow the action on our Facebook and Twitter accounts using the hashtags #agua4all and #123TCP and then re-post and re-tweet so that state policymakers know this is a priority!
Sign CWC's petition in support of a health protective 1,2,3-TCP MCL of 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 legal limit (MCL) has been established yet. Most TCP contamination stems from the extensive application of soil fumigants manufactured by Shell Oil and Dow Chemical Company containing TCP prior to the 1980s. Despite the companies’ knowledge of the health risks, they failed to remove the ingredient from their products or notify farmers of the risk.
Please prioritize creating the most health-protective MCL and ensure the polluters pay for the clean-up up this contaminant.
