What is a secondary source of contamination often found at HOT sites?

Contaminated groundwater is a significant secondary source of contamination often found at heating oil tank (HOT) sites. In the context of HOT sites, when heating oil leaks or spills occur, the contaminants can seep through the soil and into the groundwater. This groundwater can then spread the contaminants over a larger area, creating broader environmental health concerns and making it a critical focus for remediation efforts.

Groundwater contamination poses serious risks to drinking water supplies and can affect entire ecosystems if not properly managed. This makes understanding and addressing groundwater contaminants essential for ensuring the safety and health of the surrounding community and environment at HOT sites.

While contaminated surface water, dust particles, and soil erosion can also relate to contamination issues, they are not typically classified as secondary sources of contamination from heating oil tanks in the same way that groundwater is, as groundwater contamination arises directly from the movements of oil pollutants below the surface.
