State of California Department of Health Services Memorandum To David Siegel Date : November 13, 1986 Hazardous Waste Unit Subject: Marley Sampling Report From Environmental Epidemiology Unit Attached are copies of the laboratory reports for Marley Cooling Towers soil samples and an assessment by COMTU sanitarian Robert Schlag. Marley Cooling Towers is a wood preservative plant and superfund site in Stockton where cleanup of groundwater is occurring because of contamination with hexavalent chromium. On site soil has been contaminated with chromium, copper and arsenic. At the request of lawyer Victor Donahue and concerned community members samples were taken on the. morning of October 10, 1986 from various locations around the periphery of the Marley site (see attached map) . Locations were chosen with the assistance of community members who live near Marley and of Marge Rouch, TSCD. The areas were close to the Marley fence and said to be where nearby residents might have contact with soil. (Table 1) . All samples were 0-1" grab samples which were collected from bare soil areas using disposable plastic towels and held in clean glass sample containers. The results for wood preservatives arsenic, chromium, copper and zinc are shown in Table 1. Of these, results for samples 1, 4, 5, 6 and 8 are clearly higher than background samples 9 and 10. These samples were all near to Marley fences. As Bob Schlag indicates in his report, although the levels are below California Administrative Code Total Threshold Limit Concentrations, they are higher than typical environmental levels and indicate that there may be off- site migration. Could one of your toxicologists assist us in evaluating these levels, particularly with respect to possible hazards to children who may be playing in these areas? Lynn Goldman, M.D. , M.P.H.
