摘要

A New York State (NYS) land use-risk grid (Hillenbrand and Simpson 2005) was analyzed in conjunction with a NYS aquifer susceptibility grid (Hillenbrand and Friedman 2005) to derive a groundwater-risk grid; the resultant regionally-scaled grid is a measure of an unconfined aquifer's risk to receiving contaminants. The land use-risk analysis assessed the potential to introduce contaminants near the ground surface of NYS. The aquifer susceptibility analysis assessed the vulnerability of an unconfined aquifer if a contaminant source was present. Groundwater-risk was calculated by dividing the potential to introduce contaminants, land use-risk, by the potential to attenuate and retard contaminants, aquifer susceptibility. The regional groundwater-risk grid was analyzed to produce an ordinally scaled groundwater- risk grid with values from one (low risk) to seven (high risk). The confidence of the groundwater-risk grid was evaluated by correlating existing U.S. Environmental Protection Agency Comprehensive Emergency Response Compensation and Liability Act (CERCLA) National Priority List (NPL) groundwater contamination sites in NYS with the ordinally scaled groundwater-risk grid. CERCLA NPL groundwater contamination sites show a 76% con-elation of sites containing maximum groundwater-risk values of 5, 6, and 7. CERCLA NPL groundwater contamination sites also display a 47% correlation with sites containing median groundwater-risk values of 5, 6, and 7. The strong correlation of significant groundwater-risk values (values of 5, 6 and 7) with CERCLA NPL groundwater contamination sites lends a strong degree of confidence to the groundwater-risk grid's ability to assess the potential of groundwater contamination. Mean values of groundwater-risk were calculated for each county in NYS.
