Groundwater Monitoring Data for Coal Ash Ponds

Facilities that discharge wastewater to streams, lakes and other state waters are regulated through National Pollutant Discharge Elimination System – or NPDES – permits. The permits include federal and state regulatory requirements for the protection of human health and aquatic life.

Duke Energy's 14 coal-fired electric generating plants have NPDES permits to regulate their activities. As a part of permit requirements, each of the facilities is also required to monitor groundwater to determine if these resources are protected in accordance with state and federal regulation and state groundwater quality standards. The North Carolina groundwater quality standards can be found here.

If monitoring shows that the level of a contaminant exceeds what is allowed by state and federal regulations, then a process begins for evaluating proper compliance actions. The process that applies to the coal-fired electric generalting facilities is outlined here.

Groundwater monitoring data is available as an Excel spreadsheet for each of Duke Energy's 14 facilities by clicking the links below. This data is updated quarterly. A map of each facility showing the location of the groundwater monitoring wells is also provided.
