Health assessment for Rhone Poulenc (ZOECON), East Palo Alto, San Mateo County, California, Region 9. CERCLIS No. CAT000611350. Final report

Technical Report ·
OSTI ID:5050836
The Rhone Poulenc site has been proposed for listing on the National Priorities List. The site has been the location of chemical manufacturing since before 1926. Flue dust from Anaconda, Montana copper-smelting operations was used to manufacture sodium arsenate from 1920s to 1960s. The current owners have manufactured insecticides at the site from 1972 to the present. The environmental contamination on-site consists of arsenic, lead, cadmium, selenium, mercury, copper, and zinc in soil and surface water. The environmental contamination off-site consists of arsenic in surface water in the adjacent tidal marsh; and arsenic, lead, cadmium, selenium, copper, mercury, zinc in seasonally pounded surface water. In addition, soil contamination has been detected on the levy and in the tidal marsh. The site is considered to be of potential public health concern of the risk to human health caused by the possibility of exposure to hazardous substances via contaminated surface soil, sediment, and water.
