Cost Effective, Professional Environmental Solutions

Environmental Site Assessments

Greenfield Environmental, Inc. (GE) staff are trained in the newer AAI Standard and are familiar with the reporting requirements outlined in the Standards and Practices for All Appropriate Inquiries (AAI) 40 Code of Federal Regulations, Section 312 [5].
Environmental Site Assessments (ESAs)are conducted: (1) to limit the extent of the environmental liabilities to which the parties involved in real property transactions are exposed; (2) to allow the parties involved in real property transactions to more accurately appraise the value of a property, and (3) to determine potential environmental concerns at the property or on nearby properties.

The ESA process, performed in accordance with ASTM Standard Practices, is separated into phases which provide the client with a cost effective approach to investigating potential liabilities and the current level of compliance at a property.

Phase I ESAs

Include an examination of property usage and facility age, including a search of historical aerial photographs, city directories, Sanborn Fire Insurance Maps, USGS topography maps, environmental liens against the property, a review of current site operation, interviews with persons knowledgable of site history, evaluation of chemicals unitized and wastes produced, examination of environmental agency files on the property owner, tenants or adjacent properties, owners or tenants; visual inspection of the property for potential environmental problems such as chemical spills, poor housekeeping practices, visible soil contamination, storage tanks, asbestos containing materials; and assembly of the final ESA report. If the Phase I ESA produces evidence of a potential environmental problem which warrants further investigation, a Phase II Investigation may be recommended.

Phase II Investigations

Are conducted to specifically identify past petroleum, solvent or metal use at a subject site. Organic Vapor Analysis (OVA) of on-site soils is conducted to evaluate soils for petroleum hydrocarbon vapors. All soil and groundwater samples collected at a site are properly containerized, labeled and submitted to a State of Florida certified laboratory for analysis. Following the receipt of laboratory analytical results, a final report that includes all investigation methodologies, site figures, laboratory analytical results and conclusions is provided to the client. As always, the project findings are verbally discussed with the client.
