What Makes Redford's Water Unique?

Local geology and source profile

Source: RiverTDS: 452.9 mg/LpH: 8

Redford Township Water Company serves approximately 48,719 residents in Redford Charter Township, Wayne County, Michigan. The utility purchases treated surface water from the Great Lakes Water Authority (GLWA), sourced primarily from the Detroit River and Lake Huron. Water is delivered via GLWA's Water Resource Recovery Facility (formerly the Springwells Water Treatment Plant) and distributed through local infrastructure. Treatment by GLWA involves coagulation, sedimentation, filtration, and disinfection.

The supply originates in the Detroit River–Lake Huron watershed within the broader Great Lakes basin, where surface water flows through Paleozoic carbonate rock formations — specifically Devonian dolomites and limestones of the Detroit River Group and the Bois Blanc Formation. These soluble sedimentary layers contribute dissolved calcium and magnesium, imparting a hard character through natural geochemical leaching. No groundwater aquifers are involved; reliance on large riverine sources also exposes the system to watershed-wide influences like urban runoff and industrial legacy.

Very hard water promotes significant scale buildup in pipes, heaters, and fixtures, reducing efficiency and lifespan of water heaters, dishwashers, washing machines, and coffee makers. Soap lathering is poor, leading to higher detergent use. A water softener is strongly recommended; regular descaling of appliances and annual flushing of hot water tanks are advised. The 2024 Consumer Confidence Report confirms turbidity at 0.13 NTU; however, lead action level exceedance persists at 90th percentile 16 ppb (>15 ppb AL) — NSF/ANSI 53-certified filters are recommended for affected homes.

Geology & Source: Great Lakes basin surface water; Devonian Detroit River Group dolomitic limestone and Bois Blanc Formation — carbonate-rich Paleozoic bedrock dissolves calcium and magnesium into Detroit River and Lake Huron, producing hard supply

Frequently Asked Questions

Is Redford's water safe to drink?

Yes. Redford's water meets all federal safety standards. The hardness is ≈ 180+ mg/L (Very Hard), which is safe to drink. High hardness affects appliances and taste, but poses no health risk.

Do I need a water softener in Redford?

At ≈ 180+ mg/L (Very Hard), Redford's water will cause significant limescale on kettles, washing machines, and water heaters. A water softener or descaler is strongly recommended to extend appliance lifespan and reduce energy bills by up to 45%.

How does Redford compare to the USA average?

The USA national average is 151 mg/L. Redford (≈ 180+ mg/L) is 189 mg/L above the national average. The softest major city is Scarsdale at just 0.02 mg/L.

Data Sources & Methodology

Water quality data for Redford is derived from geographic and geological modelling of the surrounding region. No federal monitoring station data was available for this location.

Estimated

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.

Estimated

Estimated from regional geology and source water characteristics. pH is correlated with water hardness and local bedrock — values may differ from utility-reported figures.

Estimated

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.

Measured

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.

Modelled

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.

Calculated

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.
