What Makes Perry Hall's Water Unique?
Local geology and source profile
Perry Hall, Maryland, in Baltimore County — a major north Baltimore County suburban community (Perry Hall is a significant Baltimore County unincorporated community — one of the most populous unincorporated communities in Maryland and a primary north Baltimore County suburban area; Perry Hall has been one of the most consistently growing Baltimore County communities since the 1970s, with the White Marsh–Perry Hall corridor becoming one of the most significant north Baltimore County retail and residential corridors), home of Perry Hall High School (one of the most significant Baltimore County public high schools, known for its strong academics and athletics), a diverse Baltimore County community with a primarily working-class to upper-middle-class suburban family, Irish-American, and Italian-American population, adjacent to White Marsh and Joppa in the north Baltimore County corridor, home of the White Marsh Mall area (one of the most significant retail corridors in Baltimore County), and a growing north Baltimore County suburban community — draws its municipal water supply via the Baltimore City DPW. Water hardness in Perry Hall measures 200 mg/L — classified as hard.
Perry Hall's hard supply reflects the north Baltimore County BCDPW distribution zone's limited softening. The BCDPW distributes Prettyboy and Loch Raven Reservoir supply to the north Baltimore County Perry Hall zone with limited softening, producing the hard 200 mg/L.
At 200 mg/L, Perry Hall residents face regular hard water challenges. Monthly descaling and water softeners are 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 and Prettyboy Reservoirs (Gunpowder Falls watershed) via the Baltimore City DPW — the Baltimore County north Baltimore County suburban Perry Hall corridor (Precambrian calcareous-poor Maryland Piedmont gneiss — the calcareous-poor north Baltimore County BCDPW Gunpowder watershed; limited softening); hard supply at 200 mg/L in Baltimore County.
