What Makes Chesapeake Ranch Estates-Drum Point's Water Unique?
Local geology and source profile
Chesapeake Ranch Estates-Drum Point, Maryland, in Calvert County — a Calvert County planned community adjacent to Lusby and Prince Frederick on the Chesapeake Bay in south Maryland — receives its water from the Chesapeake Ranch Club Association (CRCA) Water or a county system, drawing from shallow Patuxent River aquifer wells through the south Maryland distribution.
The soft 95.5 mg/L hardness and TDS of 158.8 mg/L reflect the Calvert County Coastal Plain supply's soft character — the Cretaceous Patuxent Formation is primarily insoluble sand and gravel, while the Tertiary Nanjemoy Formation contributes only modest calcareous content from its marine clay minerals (compare Lusby MD: 93/154 in Calvert County comparable; Prince Frederick MD: 98/163 in Calvert County comparable; Chesapeake Ranch Estates consistent soft from the same Calvert County Patuxent Aquifer Cretaceous-Tertiary supply). The Patuxent River aquifer — Cretaceous Patuxent Formation (insoluble — primary dilutant), Tertiary Nanjemoy Formation (slightly calcareous — primary hardness contributor), and Holocene Chesapeake Bay shoreline deposits (slightly calcareous — minor TDS).
At 95.5 mg/L with TDS 159, Chesapeake Ranch Estates' water is soft — minimal scale buildup. Annual descaling is appropriate. The PFAS level of 5.0 ppt is moderate — a certified drinking water filter provides added protection. Review the Calvert County water utility's annual water quality report for the latest monitoring data.
Geology & Source: Chesapeake Ranch Estates in Calvert County draws from the CRCA Water on the Patuxent Aquifer (Calvert County, south Maryland) — the Maryland coastal plain at Calvert County is developed in Cretaceous Patuxent Formation (insoluble) and Tertiary Nanjemoy Formation (slightly calcareous) — Maryland Calvert County Patuxent Aquifer Cretaceous-Tertiary supply produces soft water at 95.5 mg/L with TDS 158.8 mg/L.
