Which contaminants are of potential concern for HOT sites?

Benzene and other volatile organic compounds (commonly referred to as BETX, which includes benzene, ethylbenzene, toluene, and xylene) along with polycyclic aromatic hydrocarbons (PAHs) are significant contaminants of concern at heating oil tank (HOT) sites. This is primarily because they originate from petroleum products, which are commonly stored in these tanks.

When a heating oil tank leaks or is inadequately managed, these substances can migrate through soil and groundwater, posing risks to both human health and the environment. Benzene is a known carcinogen and can lead to serious health issues upon exposure. PAHs are also hazardous compounds that can be harmful and are often found in products derived from petroleum.

Understanding the implications of these contaminants is critical for HOT supervisors, as they must ensure that proper protocols are followed for monitoring and remediation to minimize risks associated with these pollutants. Therefore, recognizing the potential presence of BETX and PAHs is essential for effective management and regulatory compliance at HOT sites.
