What Makes Mount Clemens's Water Unique?
Local geology and source profile
The City of Mount Clemens Municipal Water Company serves approximately 18,588 residents in Mount Clemens, Michigan, located in Macomb County. Water is sourced directly from Lake St. Clair through a 30-inch steel intake pipe extending three-quarters of a mile into the lake. The utility operates a treatment facility at One Crocker Boulevard, Mount Clemens, MI 48043, providing surface water to the community via standard municipal distribution. Annual Consumer Confidence Reports (CCRs) for 2023 and 2024 are published on the city's website at mountclemens.gov, and the utility can be reached at 586-469-6818.
The supply originates in the Lake St. Clair watershed within the broader Great Lakes basin, influenced by glacial deposits and Paleozoic sedimentary rocks of the Michigan Basin, including Devonian-age limestone, dolomite, and shale. Lake St. Clair, fed by the St. Clair River from Lake Huron, dissolves minerals from these carbonate-rich formations, resulting in a hard supply characterized by elevated calcium and magnesium. The regional geology promotes mineral pickup without significant softening, typical of Great Lakes surface sources.
Hard water causes scale buildup in pipes, water heaters, dishwashers, and washing machines, reducing efficiency and lifespan — white deposits, reduced flow, and higher energy use are common signs. Regular heater flushing, vinegar descaling for fixtures, and installing sediment filters help manage accumulation. A water softener is recommended to protect plumbing and improve soap efficiency. The 2024 CCR confirms EPA compliance; pH is typically 7.5–8.5, lead and copper are under action levels with corrosion control, and PFAS presence has been noted with filter recommendations.
Geology & Source: Lake St. Clair watershed; Pleistocene glacial lake underlain by Devonian limestone and dolomite — Michigan Basin Paleozoic bedrock; calcium and magnesium leached from carbonate rocks produce hard supply

Data Sources & Methodology
Water quality data for Mount Clemens is derived from geographic and geological modelling of the surrounding region. No federal monitoring station data was available for this location.
Water Hardness
Modelled estimate based on state-level USGS geological survey data for this region. No direct USGS Water Quality Portal measurement was matched to this city — the value reflects a statistical range calibrated to the state's dominant rock types and typical source water characteristics.
pH
Estimated from regional geology and source water characteristics. pH is correlated with water hardness and local bedrock — values may differ from utility-reported figures.
TDS — Total Dissolved Solids
Estimated using a derived ratio from water hardness and regional conductance profiles. TDS in natural water correlates strongly with total mineral content including hardness ions.
PFAS — Perfluoroalkyl and Polyfluoroalkyl Substances
EPA UCMR5 (5th Unregulated Contaminant Monitoring Rule, 2023–2025) — sum of PFAS compounds detected at the public water system serving this city. A value of 0 indicates the system was sampled with no detection above reporting limits.
Lead
Modelled estimate based on the EPA Lead and Copper Rule 90th-percentile tap-sample methodology. No publicly available per-city lead dataset with sufficient national coverage exists. Values are a conservative baseline derived from city population tier and infrastructure age — all estimates are maintained below the EPA action level of 0.015 mg/L.
Appliance Lifespan
Calculated from water hardness using a linear degradation model. Baseline lifespans represent soft-water performance (kettle: 8.5 yrs, washing machine: 12.0 yrs, water heater: 15.0 yrs). Hard water mineral scale progressively reduces operational life in direct proportion to hardness concentration.
