ASTM Phase I & Phase II Environmental Site Assessments

Our Phase I & Phase II environmental site assessment (ESA) reports traditionally exceed industry standards and lending protocols. We work with our clients to document known and potential site conditions that may affect property values or lead to additional liability. All of our real estate environmental assessments are, and have always been, performed by senior environmental professionals supported, when necessary, by technical specialists in areas such as asbestos, lead, radon, PCBs, underground storage tanks, and building reclamation. You can count on us to describe our findings accurately and understandably—providing you with user-friendly information that you can rely on to protect your investment.


Environmental Site Assessment – Phases I and II

Phase I Investigation
• Document existing conditions
• Record evidence of impairment
• Identify past uses and operations
• Assess and qualify level of risk
• Provide data to support transaction or recommend further investigation

Site Reconnaissance
• Thoroughly inspect site
• Inspect surrounding land and use
• Interview site personnel
• Review on-site records
• Observe controlling geologic and hydrologic features

Land Use and Records Search
• Property titles, past tenant land use records, and archival records
• Aerial photos, site maps, plans
• Interview past property owners
• Construction and alteration records
• Regulatory environmental records

Data Evaluation
• Published regional geologic data
• Previous investigatory data
• Local groundwater quality, water level, and usage patterns
• Hydrologic conditions

Phase II Investigation
• When contamination is identified
• Site exploration, sampling, monitoring, and laboratory analysis to quantify and classify potential contamination

Sampling and Field Testing
• Representative sampling of all potentially contaminated areas
• Assess extent and severity of site contamination
• Soil borings, test pits, sampling
• Content sampling of lagoons, tanks, drums, sumps, etc.
• Explore suspected fill areas
• Sampling of past spill areas
• Liquid and sediment sampling in ponds, ditches, streams, leachate seeps, and general surface runoff
• Soil vapor surveys
• Geophysical surveys
• Tank leakage testing
• Radon and asbestos testing

Hydrogeologic Assessments
• Monitor roundwater for extent and severity of subsurface contamination
• Characterize hydrogeology of site and surrounding area
• Assess groundwater flow and quality
• Delineate contaminant plumes
• Soil vapor monitoring
• Measure hydrocarbon product thickness

Laboratory Analysis to Characterize On-Site Contamination

Remediation Assessment and Recommendations
• Recommendations for cleanup and treatment at contaminated sites
• Physical, chemical, and biological treatment approaches
• UST removal and product recovery
• Aquifer restoration
• In situ lagoon restoration
• Sludge dewatering
• Waste stabilization/solidification
• Soil venting and aeration
• Hazardous materials excavation
