An Environmental Site Assessment (ESA) is an evaluation for the environmental conditions of a property. ESA’s can help to identify potential or existing environmental contamination that can impact the property value and/or usability.
Phase 1 ESA: This initial assessment involves a review of the property’s historical and current use, as well as an inspection of the site and surrounding areas
Phase 2 ESA: If the Phase I ESA indicates potential contamination concerns, a Phase II ESA involves more detailed testing and sampling.
During an Environmental Site Assessment (ESA), a variety of common contaminants are investigated, depending on the property’s history and potential sources of pollution. Here are some typical contaminants that are often looked for:
Petroleum Hydrocarbons:
Gasoline, Diesel, and Oil: Often found in sites with former gas stations, industrial facilities, or auto repair shops.
Heavy Metals:
Lead, Cadmium, Chromium, and Mercury: Common in sites with past industrial activities, battery manufacturing, or hazardous waste disposal.
Volatile Organic Compounds (VOCs):
Benzene, Toluene, Ethylbenzene, and Xylenes (BTEX): Frequently associated with petroleum products and solvents used in industrial processes.
Polychlorinated Biphenyls (PCBs):
Found in older electrical equipment, transformers, and some building materials like caulking and paint.
Asbestos:
A hazardous material commonly found in older buildings in insulation, flooring, and roofing materials.
Pesticides and Herbicides:
Often detected at agricultural sites or former sites with extensive land management activities.
Chlorinated Solvents:
Trichloroethylene (TCE), Perchloroethylene (PCE), and Dichloromethane: Common in dry cleaning operations, degreasing activities, and industrial cleaning.
Radon:
A naturally occurring radioactive gas that can accumulate in buildings, particularly in areas with certain geological conditions.
Cyanides:
Found in industrial processes, particularly in metal plating and mining operations.
Nutrients:
Nitrates and Phosphates: Can be a concern in sites with heavy agricultural use or wastewater treatment issues.
Microbial Contaminants:
Bacteria, Viruses, and Fungi: Can be found in sites with issues related to waste disposal or inadequate sanitation.
If needed, a Phase II ESA can be conducted to identify the extent of contamination and to recommend strategies for clean-up and remediation. Beyond that, our professional staff can assist with assembling the most cost-effective clean-up and remediation crews to restore property value.
