Parole Water Hardness & Quality Report (2026)

Parole, Maryland, in Anne Arundel County — an unincorporated Anne Arundel County community adjacent to Annapolis and Edgewater in central Maryland — receives its municipal water from the Anne Arundel County Department of Public Works (DPW), drawing from the Patuxent River or Severn Run (Anne Arundel County) through the Annapolis metro distribution.

The hard 187.5 mg/L hardness and elevated TDS of 481.5 mg/L are significantly harder than the WSSC-served Maryland City (161 mg/L) in the same Anne Arundel County, suggesting Parole's Annapolis-area distribution draws from a harder supply zone with stronger Triassic Newark calcareous input. The Patuxent River and Severn Run drainage at central Anne Arundel County draw from the Maryland Piedmont — Triassic Balls Bluff Siltstone (calcareous redbeds — the primary hardness source), Precambrian Glenarm Group Gneiss (moderately insoluble), and Cambrian Weverton Formation (moderately calcareous).

At 187.5 mg/L, Parole's water is hard — scale builds steadily in kettles and appliances, dishwashers benefit from rinse aid, and water heaters should be descaled annually. Monthly descaling is recommended. The PFAS level of 10.3 ppt warrants a certified reverse osmosis drinking water filter — Fort Meade (Anne Arundel County — AFFF, the dominant central Maryland PFAS source) and the Washington-Baltimore PFAS complex contribute to Parole's elevated readings.
