Ross Valley Sanitary District begins toxin cleanup in Larkspur
Contractors are busy digging, stockpiling and hauling off an average of 40 truckloads of contaminated soil a day from the site of a former wastewater treatment plant at Larkspur Landing. About 64,000 tons of the mixed soil and demolition debris, which contains trace amounts of polychlorinated biphenyls, or PCBs, will be sent to a municipal landfill, while another 2,600 tons, will be shipped to a hazardous waste landfill.
