What are the issues with brownfield sites?

Brownfields can also directly impact public and environmental health due to contamination that can pollute soil, air, and water resources on- and off-site. People might be exposed to these hazards by walking on the site, by wind carrying contamination off of the site, or by drinking groundwater affected by the site.
