What Makes Mitchellville's Water Unique?
Local geology and source profile
Mitchellville, Maryland, in Prince George's County — a Prince George's County unincorporated community adjacent to Bowie and Upper Marlboro in the DC eastern suburbs — receives its water from the Washington Suburban Sanitary Commission (WSSC), drawing from the Patuxent River through the central Maryland distribution.
The very hard 199 mg/L hardness and high TDS of 533.3 mg/L reflect the Prince George's County Patuxent supply's very hard calcareous character — the Cambrian Conococheague Limestone and Ordovician Frederick Limestone are highly calcareous formations in the Maryland Piedmont, and the Patuxent River acquires substantial dissolved mineral content from its extensive limestone drainage in the Piedmont and Blue Ridge (compare Bowie MD: 195/522 in Prince George's County comparable; Upper Marlboro MD: 202/544 in Prince George's County comparable; Mitchellville consistent very hard from the same Prince George's County Patuxent River Ordovician calcareous supply). The Patuxent watershed — Cambrian Conococheague Limestone (calcareous — primary hardness contributor), Ordovician Frederick Limestone (calcareous — secondary contributor), and Quaternary Patuxent alluvium (calcareous — TDS contributor).
At 199 mg/L with TDS 533, Mitchellville's water is very hard — a water softener is strongly recommended to protect plumbing and appliances. The PFAS level of 10.9 ppt is very high — a certified filter with PFAS removal is strongly recommended — the Prince George's County DC metro military/industrial legacy contributes to Mitchellville's very elevated PFAS readings. Review WSSC's annual water quality report.
Geology & Source: Mitchellville in Prince George's County draws from the WSSC on the Patuxent River supply (Prince George's County, central Maryland) — the Patuxent watershed drains Cambrian Conococheague Limestone (calcareous) and Ordovician Frederick Limestone (calcareous) — Maryland Prince George's County Patuxent River Ordovician calcareous supply produces very hard water at 199 mg/L with TDS 533.3 mg/L.
