" ... Source Control/Ground Water Interim Actions (SC/GWIA) were required by an April 1, 2002 Administrative Consent Order (ACO) issued to YSI by the Ohio Environmental Protection Agency. The ultimate objective of the SC/GWIA order is to accomplish remediation goals for impacted soils and groundwater at the facility. Toward that end, the order describes a process of identifying and characterizing impacted source-area soils, assessing impacts to groundwater, establishing remediation goals, and developing and implementing interim remedial measures. The general approach for delineating and characterizing source areas consisted of identifying the presence or absence of contaminants in suspect source areas, characterizing conditions in source areas impacted by COCs [compounds of concern], developing groundwater compliance levels for COCs, then developing soil remediation goals for the COCs ... Once source areas were characterized and remedial goals were established, soils in source areas with COCs exceeding goals and requiring remediation were identified. Conceptual remedial approaches for meeting standards were assessed ... Based on this assessment, remedial approaches were selected and conceptual designs were developed."--Introduction, p. 3.
