Hazards Found on Brownfields
Brownfield sites cannot have a level of contamination that would place them on either the National Priority List (NPL) or a State priority list. Sites where levels of contamination do not warrant inclusion on either type of priority list are not likely to cause immediate or serious health effects to individuals living or working around them, although they may pose hazards for employees conducting work on the site. Thus, brownfield sites are generally not highly contaminated, however the types and levels of contaminants present can vary considerably among them.
Hazardous substances found on brownfields may include:
- petroleum hydrocarbons,
- gasoline or diesel fuel,
- metals,
- construction debris containing asbestos or lead paint,
- polychlorinated biphenyls (PCBs),
- wood-treating chemicals, and
- industrial chemicals.
They may be present in air, soil, sediment, surface or ground water, and in structures or containers at the site.
