US university sues Dow over pollution

West Virginia State University (WVSU) in the US is suing Dow Chemical for contaminating the groundwater beneath its campus with three hazardous chemicals. The university acknowledges agreement by outside experts and the US Environmental Protection Agency (EPA) that these contaminants do not pose a threat to human health because the WVSU uses municipal water, not groundwater. However, the university says the contamination will limit future construction on a large part of its campus, and wants Dow to pay for the necessary clean-up.
