BIOSIS COPYRIGHT: BIOL ABS. The contribution of heavy metals from sources including household washing products, other residential sources, water supply and permitted industry to influent wastewater and treated effluent was determined for the wastewater treatment plants of the cities of San Joseanta Clara, Palo Alto and Sunnyvale, which are located in the Southern San Francisco Bay Area of Calif. The heavy metals studied were arsenic, cadmium, chromium, copper, lead, mercury, nickel, silver, and zinc. In no case were household washing products the major heavy metal contributor to influent wastewater or wastewater effluents. The highest heavy metal contribution from household washing products was from arsenic. It accounted for 13% of the influent and effluent wastewater arsenic content. All other household washing product heavy metals contributions to influent and effluent wastewater were below 0.5% of the total metal present.
