Environmental Site Assessments
Be An Informed Consumer
Purchasing a new property requires extensive research and knowledge. The first step in obtaining a property is having a skilled Environmental Consultant inspect and determine the location of any potential hazards and identify any environmental constraints. An assessment and identify is a detailed inspection and report of a property and it’s surroundings. An environmental assessment consists of a detailed inspection and preparation of a report outlining any environmental constraints associated with the development of the property. A report is prepared for real estate holdings that identify existing or potential environmental contamination liabilities. The analysis, often called an ESA, typically addresses both the underlying land as well as physical improvements to the property.
Stillwater Environmental understands that it can be daunting and costly in dealing with hazardous waste contamination discovered on property you have recently acquired or considered to acquire. Performing an environmental site assessment prior to acquiring a property can minimize cost & risk.
Phase I Environmental Site Assessments
The Phase I ESA is considered the first step in the process of environmental due diligence. Standards for performing a Phase I site assessment have been promulgated by the US EPA and are based in part on ASTM in Standard E1527-13. If a site is considered contaminated, a Phase II environmental site assessment may be conducted, ASTM test E1903, a more detailed investigation involving chemical analysis for hazardous substances and/or petroleum hydrocarbons.
Phase 2 Environmental Site Assessments
Phase II Environmental Site Assessment is a more detailed and an “intrusive” investigation which collects original samples of groundwater, soil, or building materials to analyze for various contaminants. The most tested substances are petroleum hydrocarbons, heavy metals, pesticides, solvents, asbestos and mold. This investigation is normally undertaken when a Phase I ESA determines a possibility of site contamination.
