What Makes Allen Park's Water Unique?
Local geology and source profile
Allen Park, Michigan, in Wayne County — a major south Detroit suburban community (Allen Park is a significant Wayne County city — a south Detroit suburb adjacent to Dearborn and Lincoln Park; Allen Park is a classic post-WWII south Detroit working-class suburban community that grew as Detroit's automotive industry workers sought affordable homes in the Wayne County south suburban belt; Allen Park is known for its proximity to the Ford Motor Company Dearborn operations and the River Rouge complex (one of the most historically significant automotive manufacturing facilities in the world — Ford's River Rouge Complex at Dearborn is the largest integrated automotive plant ever built; it once housed its own iron ore to steel to finished automobile production chain under one company umbrella)), a diverse Wayne County community with a primarily Italian-American, Polish-American, and working-class suburban population, adjacent to Dearborn and Ecorse in the south Wayne County corridor — draws its municipal water supply via the Great Lakes Water Authority. Water hardness in Allen Park measures 216.5 mg/L — classified as hard.
Allen Park's hard supply reflects the south Detroit Wayne County GLWA Great Lakes supply's limited softening. The GLWA distributes Detroit River–sourced supply to the south Wayne County Allen Park zone with very limited softening, producing the hard 216.5 mg/L.
At 216.5 mg/L, Allen Park residents face regular hard water challenges. Monthly descaling and water softeners are recommended. Great Lakes Water Authority consistently delivers water meeting all Michigan EGLE and EPA Safe Drinking Water Act requirements.
Geology & Source: River supply from the Detroit River (Lake Erie watershed) via the Great Lakes Water Authority — the Wayne County south Detroit suburban Allen Park corridor (Devonian calcareous Detroit River Group dolomite — the extremely calcareous south Detroit Wayne County Great Lakes supply; very limited softening); hard supply at 216.5 mg/L in Wayne County.
