Per the conditions of Permit No. WV0700153, monthly groundwater samples are required to be collected from the well system during operation of the wells on a monthly basis. Groundwater samples will be analyzed for Fecal Coliform, chlorides, and nutrients (Total Nitrogen, Ammonia, Nitrate, Total Phosphorus). The volume of water pumped from the well system shall be monitored and tracked with flows reported on a monthly basis. Enclosed for your records, are the results from the August 2020 reporting period for Permit No. WV0700153 for the Nags Head Acres Dewatering Well project.
