Phase I: This site assessment is conducted by examining local, state, and federal records to determine if the potential for environmental conditions exist. The site is also inspected and interviews are conducted with the owners and occupants of the property. All findings are reported to help determine if further inspection is necessary.
Phase II: The Phase II assessment is conducted with soil, soil gas, and groundwater samples taken from monitoring wells and boring. Testing these samples provides a comprehensive analysis of environmental conditions on the property and may indicate contaminants in the area.
Phase III: Phase III is called for when contamination is found in a Phase II assessment. After reviewing documents from Phase I and Phase II, hydrology and the geology of the subsurface soil is determined. The spread of contamination to other areas is measured and the extent of groundwater contamination is determined.
