What Makes Park View's Water Unique?
Local geology and source profile
Park View, in the District of Columbia — a DC neighborhood adjacent to Petworth and Columbia Heights, in the northwest DC corridor along the Georgia Avenue corridor — receives its municipal water from DC Water, drawing from the Potomac River at the McMillan Sand Filtration Site and Dalecarlia Water Treatment Plant.
The moderately hard 118 mg/L hardness and TDS of 274.2 mg/L are essentially identical to the Petworth DC supply (119.5 mg/L, TDS 281) — naturally, as both Park View and Petworth receive the same DC Water Potomac supply from the same treatment facilities in northwest DC. The Potomac River at Washington DC carries the combined Blue Ridge and Appalachian Great Valley carbonate drainage, producing the moderately hard water characteristic of the DC municipal supply.
At 118 mg/L, Park View's water is moderately hard — scale builds in kettles and appliances over months, dishwashers benefit from rinse aid, and faucet aerators need periodic cleaning. Quarterly descaling is appropriate. The PFAS level of 7.9 ppt warrants a certified drinking water filter — Joint Base Andrews (Prince George's County — AFFF PFAS source), the Potomac River PFAS industrial corridor, the W.L. Gore Elkton MD legacy, and the DC metro PFAS complex contribute to Park View's elevated readings.
Geology & Source: Park View in DC draws from DC Water on the Potomac River (McMillan and Dalecarlia water treatment plants) — the Potomac drains the Blue Ridge (Precambrian Catoctin metavolcanic) and Great Valley carbonate (Cambrian-Ordovician limestone) — Blue Ridge-Appalachian carbonate Potomac River drainage produces moderately hard water at 118 mg/L with TDS 274 mg/L in this District of Columbia neighborhood.
