Winchester Water Hardness & Quality Report (2026)

Winchester, Virginia — an independent city and major Shenandoah Valley community (Winchester is one of the most historically significant cities in Virginia — a city that changed hands over 70 times during the Civil War (Winchester's strategic location at the north end of the Shenandoah Valley made it one of the most contested cities in the Civil War; both Union and Confederate forces occupied and evacuated Winchester multiple times during the war, and three significant Civil War battles were fought at or near Winchester (the First, Second, and Third Battles of Winchester))); Winchester is the gateway to the Shenandoah Valley and the home of Shenandoah University (a significant Virginia private university) and Apple Blossom Mall (one of the most important regional shopping centers in the north Shenandoah Valley); Winchester is known as the 'Apple Capital of the World' (the Frederick County–Winchester area is one of the most important apple-growing regions in the eastern United States — Virginia's Shenandoah Valley apple orchards are a major agricultural and cultural feature), a diverse Winchester City community with a significant Hispanic-American, agricultural, and military–government professional population — draws its municipal water supply via the City of Winchester Water Division. Water hardness in Winchester measures 103 mg/L — classified as moderately hard.

Winchester's moderate hardness reflects the north Virginia Shenandoah Valley carbonate karst's calcareous character with effective treatment. The Shenandoah Valley Carbonate aquifer draws from the Ordovician Beekmantown Dolomite (calcareous). City of Winchester treatment produces the moderate 103 mg/L.

At 103 mg/L, Winchester residents encounter moderate scale accumulation. Monthly cleaning is recommended. City of Winchester Water Division consistently delivers water meeting all Virginia DEQ and EPA Safe Drinking Water Act requirements.
