The Prince William County Service Authority releases its 2023 Water Quality Reports, which provide important information about the source and characteristics of the utility’s drinking water. The reports are available on the Service Authority’s website.

Each of the Service Authority’s five distribution systems – East, West, Hoadly Manor, Carter’s Grove, and Bull Run Mountain and Evergreen – has its own Water Quality Report. As noted in the reports, the Service Authority’s drinking water met all federal and state water quality requirements for calendar year 2022, which is the most recent regulatory period.

“We are celebrating our 40th year of providing an essential service to residents, businesses and visitors in Prince William County,” said General Manager/CEO Calvin D. Farr, Jr. “A lot has changed in the first four decades, but what hasn’t changed is that our customers can depend on the quality of their water and the reliability of our service.”

Except for drinking water in the Bull Run Mountain and Evergreen communities, the drinking water distributed by the Service Authority is sourced from the Potomac River, Occoquan Reservoir and Lake Manassas. While most of the drinking water the Service Authority provides to customers is treated at facilities owned and operated by Fairfax Water, many customers in the western end of the county receive some water treated at the City of Manassas Water Treatment Plant. Customers in the Bull Run Mountain and Evergreen communities receive their water from six public groundwater wells located throughout the area.

The U.S. Environmental Protection Agency and Virginia Waterworks Regulations require all water utilities to produce annual water quality reports.
