Contaminant

Definition

A contaminant is any substance, element, or compound that poses a potential risk to human health or the environment. Contaminants commonly are in concentrations above acceptable levels or present in areas where they are not supposed to be. In real estate, contaminants become a serious issue during the due diligence process when properties are assessed for potential environmental hazards.

Examples of Contaminants

Asbestos: A hazardous mineral once used in building insulation and fireproofing.
Benzene: A byproduct of petroleum, often linked to leaking storage tanks or industrial waste.
Radon: A radioactive gas naturally occurring from underground.
PCBs (polychlorinated biphenyls): Industrial chemicals found in old electrical transformers.
Perchloroethylene (PCE): A solvent commonly used in dry cleaning.
Lead-based paint: Common in older structures, leading to health risks, particularly for children.

Frequently Asked Questions

What is the importance of identifying contaminants in real estate?

Identifying contaminants is crucial to ensure the safety and legality of property transactions. Contaminants can affect property value and usability, and failure to address them can lead to legal liabilities, health risks, and financial loss.

How are contaminants detected on a property?

Contaminants are detected through various environmental assessments such as Phase I and Phase II Environmental Site Assessments (ESAs), which may include soil sampling, water quality tests, and air monitoring.

What regulations govern the management of contaminants?

Several federal, state, and local regulations govern the management of contaminants. Key legislations include the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), the Resource Conservation and Recovery Act (RCRA), and various state-level environmental protection laws.

Who is responsible for contaminant cleanup?

Typically, the property owner is responsible; however, liability can extend to previous owners/operators. Regulatory bodies may take action to enforce cleanup and manage the risks.

What are the health impacts of exposure to contaminants?

Health impacts vary based on the contaminant but can include respiratory problems, cancer, neurological damage, and other serious health issues.

Environmental Due Diligence: The process of assessing a property for environmental contaminants before transaction.
Maximum Contaminant Level (MCL): The highest allowable concentration of contaminants in drinking water as determined by regulatory standards.
Phase I Environmental Site Assessment: An initial evaluation of a property’s environmental condition and identification of potential contamination risks.
Phase II Environmental Site Assessment: A detailed investigation involving sampling and lab analysis to confirm the presence of contaminants.
