Phase II evaluations include subsurface investigations, building material analysis, and air quality studies, to determine if a hazardous material release has adversely affected the environment via air, soil, and/or groundwater. After samples are analyzed, resulting data is interpreted and evaluated and recommendations for remedial action or closure are compiled in a report.
Phase III includes the selection of a remedial technique, development of a timeline, estimation of cost, and direction of remediation procedures. After satisfactory levels are attained, in accordance with regulatory standards, a final report is submitted to the responsible agency requesting site closure. Following closure approval, the property is available for use.
