What Makes Milford Mill's Water Unique?
Local geology and source profile
Milford Mill, Maryland, an unincorporated community in Baltimore County — a major northwest Baltimore County suburban community (Milford Mill is a significant Baltimore County unincorporated community — a northwest Baltimore County suburb along the Liberty Road corridor adjacent to Pikesville and Randallstown; Milford Mill experienced significant demographic transformation beginning in the 1990s and 2000s, with substantial African-American middle-class migration from Baltimore City and inner Baltimore County suburbs to the northwest Baltimore County Liberty Road corridor), a diverse Baltimore County community with a predominantly African-American, working-class, and middle-class professional population (Milford Mill is one of the most predominantly African-American unincorporated communities in Baltimore County), adjacent to Randallstown and Owings Mills in the northwest Baltimore County corridor, home of the Milford Mill Academy (one of the significant Baltimore County public high schools), and a community that is part of the northwest Baltimore County Liberty Road corridor — draws its municipal water supply via the Baltimore City DPW. Water hardness in Milford Mill measures 190 mg/L — classified as hard.
Milford Mill's hard supply reflects the northwest Baltimore County BCDPW distribution zone's limited softening. The BCDPW distributes Liberty Reservoir supply through the northwest Baltimore County Milford Mill zone with limited softening, producing the hard 190 mg/L.
At 190 mg/L, Milford Mill 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 Liberty Reservoir (North Branch Patapsco watershed) via the Baltimore City DPW — the Baltimore County northwest suburban Milford Mill corridor (Precambrian calcareous-poor Maryland Piedmont gneiss — the BCDPW northwest Baltimore County distribution to Milford Mill zone; limited softening); hard supply at 190 mg/L in Baltimore County.
