According to the non-profit Environmental Working Group, California’s public water systems in the San Joaquin Valley and urban areas like LA and San Bernardino and San Mateo counties are contaminated with a very dangerous, cancer-causing chemical known as 1,2,3 trichloropropane (“TCP”). Evidently, the TCP is a remnant of a chemical manufactured by Dow Chemical and Shell Oil.
The California State Water Board is proposing to limit the allowable concentration of TCP in drinking water to 5 parts per trillion. Fine. But who’s going to clean up the TCP? Are Dow and Shell responsible for the TCP in the water systems? The Water Board should also be looking into that. Because it’s not enough to just tell people how dangerous TCP is……the point is to get the TCP out of their water as soon as possible.
