Protecting & Conserving California's Water

Senators Portantino and Gonzalez Introduce Clean Water Legislation to Monitor PFAS Chemical Contamination

“Understanding the full extent of PFAS contamination in California's drinking water is critical to both protect the public and enable us to make the most cost-effective decisions about water treatment,” said Andria Ventura, toxics program manager for Clean Water Action. “We don't want to have to keep rethinking technical investments because we didn't have a full understanding of the problem.  That's not fair to water systems or ratepayers.”

Because pesticides are meant to kill living organisms, they are by their nature, toxic. However one chemical — 1,2,3-TCP, or Trichloropropane — was particularly toxic to humans and persistent in the environment.

And even on a day when we’re not focused on a pandemic, groundwater can be easy to forgot about -- it's our invisible resource.

Yesterday, the State Water Resources Control Board voted to create a new legal limit on 1,2,3-Trichloroproane (TCP), a man-made, carcinogenic drinking water contaminant found across California. This is the culmination of years of work from Clean Water Action members like you, holding Shell Oil and Dow Chemical accountable for their failure to put public health above their profits, when they first learned of the dangers of TCP.

Now comes the hard work as water agencies work to comply with the new rule.
