How does the leakage at Mount Hoy affect drinking water?
When the EPA originally scored the site, it did not find any connection between the site and contaminated supplies of drinking water. It listed the site because of the number of people who lived in the general area and because a potential did exist for contaminated drinking water. Today, ongoing monitoring has detected contaminated groundwater only within 200 feet of Mount Hoy, and none of the contamination exceeds any health-based standards for drinking water.
