+NOTE: Reported concentrations of lead in soil and sediment samples collected during the remedial investigation (RI) were considered suspect. Supplemental sampling of lead in soils and sediment at the site and the adjacent Skate Estate Facility was conducted in February and September of 1992. Of the 194 supplemental soil and sediment samples collected, analytical results indicated that lead ranged from "not detected" to 344 mg/kg. Only one sample contained lead at 344 mg/kg which is only slightly above the general background range (0-300 mg/kg); 157 of the samples contained lead at levels below 50 mg/kg, 28 samples contained lead within 50 mg/kg-100 mg/kg, 4 samples contained lead within 100 mg/kg to 150 mg/kg and 3 samples contained lead within 200 mg/kg-250 mg/kg. Background soil samples were collected during the February 1992 supplemental sampling from three locations unassociated with the site. Results of the background samples reported lead at 52 mg/kg and 93 mg/kg; one background soil sample reportedly contained lead at 2,550 mg/kg and is considered anomalous as it was collected from a location characterized by "historical disposal of household debris and automotive waste materials, including oil cans and used oil filters." Based on the results of the supplemental investigations of lead in soils and sediment, lead is not being considered as a contaminant selected for further evaluation.
