What's in Berkeley County, WV tap water?
Berkeley County sits about 63 miles from our Arlington base and is served primarily by Berkeley County PSWD (Potomac River), which provides water to roughly 34,786 people. It draws from the Shenandoah Valley & Blue Ridge karst. The Shenandoah Valley and Blue Ridge run on limestone karst springs and municipal and private wells. That geology, plus valley agriculture, tends to raise nitrate and naturally occurring radionuclides, alongside chlorination byproducts wherever the supply is disinfected.
