Hazardous Waste in Ogle and Winnebago Counties: Potential Risk via Groundwater due to Past and Present Activities

摘要

This report identifies current and historical hazardous waste activities in Ogle and Winnebago Counties. A total of 88 and 805 active and 3 and 170 inactive or abandoned sites were identified in Ogle and Winnebago Counties, respectively. Accompanying data on the types, quantities, and management practices of hazardous wastes also were gathered. The legal locations and dates of operation of each site also were tabulated. A preliminary rating scheme was developed to prioritize areas or sites that merit more detailed study and evaluation. The focus of the rating scheme is the assessment of a site's 'threat to human health via groundwater.' The ranking scheme is divided into four factors: I-Health risk of waste and handling mode; II-Population at risk; III-Proximity of waste to public water supply wells or potable aquifers; and IV-Aquifer susceptibility.
