What Makes Carney's Water Unique?
Local geology and source profile
Carney, Maryland, an unincorporated community in Baltimore County — a major northeast Baltimore County suburban community (Carney is a significant Baltimore County unincorporated community — a northeast suburban community along the Harford Road and Joppa Road corridors in Baltimore County; Carney is adjacent to Parkville and Overlea in the classic northeast Baltimore County post-WWII suburban belt, known for its solid working-class and middle-class family neighborhoods), a diverse Baltimore County community with a primarily Irish-American, Polish-American, and working-class suburban population, adjacent to Parkville and White Marsh in the northeast Baltimore County corridor, home of a significant northeast Baltimore County residential community, and a community that is part of the greater Towson–northeast Baltimore County suburban market area — draws its municipal water supply via the Baltimore City DPW. Water hardness in Carney measures 109.5 mg/L — classified as moderately hard.
Carney's moderate hardness reflects the northeast Baltimore County BCDPW distribution zone's effective treatment. The BCDPW distributes Loch Raven Reservoir supply through the northeast Baltimore County Carney zone, producing the moderate 109.5 mg/L.
At 109.5 mg/L, Carney residents encounter moderate scale accumulation. Monthly cleaning is recommended. Baltimore City DPW consistently delivers water meeting all Maryland MDE and EPA Safe Drinking Water Act requirements.
Geology & Source: Reservoir supply from the Loch Raven Reservoir (Gunpowder watershed) via the Baltimore City DPW — the Baltimore County northeast suburban Carney corridor (Precambrian calcareous-poor Maryland Piedmont gneiss — the BCDPW northeast Baltimore County distribution to Carney zone; effective treatment); moderately hard supply at 109.5 mg/L in Baltimore County.
