Tests: Drinking water safe near Brentwood park
Tests show that drinking water hasn't been tainted by toxic waste dumped near Roberto Clemente Park, but concerns remain in Brentwood.
About 50,000 tons of asbestos-laced debris and pesticides have been dumped at the park. Pesticides have been found in groundwater outside the park.
It is unclear why there is chemical contamination outside the dumping area.
