Health assessment for Marley Cooling Tower Company, Stockton, California, Region 9. CERCLIS No. CAD009140120. Preliminary report

Technical Report · Fri Mar 17 04:00:00 EST 1989

OSTI ID:5150812

The Marley Cooling Tower Company site is on the National Priorities List. Chromated copper arsenate was used to pressure-treat wood from 1966 to 1982. Preliminary on-site sampling results have identified hexavalent chromium in the shallow aquifer (1,200 ppm), intermediate aquifer (1 ppm), and surface impoundment (3 ppm). In addition, arsenic and chromium were identified in subsurface soil (4,670 and 4,270 ppm respectively). Preliminary off-site ground water sampling information identified hexavalent chromium (800 to 1,500 ppb). The site is considered to be of public health concern because of the risk to human health caused by the likelihood of human exposure to hazardous substances. Direct contact with, ingestion, and inhalation of contaminated ground water, surface water, soil, and sludge are the possible routes of human exposure.
