California’s Plan to Tackle a Carcinogen Widespread in Water

If you drive Highway 99 through California’s Central Valley, you’ll pass through the heart of farm country, where the state’s bounty blooms with hundreds of crops – everything from peaches to pistachios, from tangerines to tomatoes. You’ll also pass through dozens of communities, large and small, whose water systems are tainted by a newly regulated contaminant, 1,2,3-trichloropropane (TCP), which for decades was used in agricultural fumigants injected into farmland across the Valley.
