In August 1995, IEPA collected eleven sediment samples and three residential well water samples. Analytical sediment samples contained levels of volatile and semivolatile organic compounds, pesticides, and inorganic compounds. Sample results from the private wells did not indicate the presence of semivolatile or inorganic compounds. Figure 2 depicts the areas where samples were collected. Sediment sample analysis results are summarized in Table 1.
The maximum concentration of each contaminant was compared with appropriate screening comparison values, when available, to select contaminants for further evaluation for both carcinogenic and non-carcinogenic health endpoints. A detailed discussion of each comparison value used is found in Attachment 1. Chemicals that exceeded comparison values were selected for further evaluation.
Residential well water did not contain contaminants at levels above comparison values. The results of sediment analysis indicated that benzo(a)pyrene (Table 2) may have exceeded soil comparison values. The result was an estimated value because either the sample as collected or the equipment used to analyze the sample prevented an exact measurement of the quantity of benzo(a)pyrene present in the sediment. Because of the low concentrations detected and the low activity on the site, none of the PAHs detected in the on-site sediments would be expected to pose any adverse health effects to individuals directly exposed to the contaminant through ingestion, inhalation, or dermal contact. Additionally, there is no apparent increased cancer risk to anyone who might be exposed to the PAHs at the site. Residents of the home on the site are not expected to be exposed to contaminants at levels of health concern.
