Protecting & Conserving California's Water

TCP in California's Drinking Water

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.

Perchlorate in California's Drinking Water

California is one of only two states that have set enforceable drinking water standards for the chemical perchlorate in drinking water.

Earth Day has always had a special meaning for me – a birthday for Earth and a call to action to do what we can to protect it. In 1970, I organized the very first Earth Day event at my school in Oakland. Eschewing the bus, I enlisted a crew of friends in a bike caravan to ride 10 miles to school. Alarmed by the oil spills along the coast, and the poisoning of wildlife and humans from DDT, my classmates and I led a day long teach-in. This was the spark that ignited what has become a lifelong career as an activist.

With all that’s happening right now, it can be difficult to pay attention to  anything other than the news of the day. I’m focused on groundwater; how we use it – and use too much; how we protect it from pollution – or don’t; and how we can ensure that it’s available when we need it. 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.
