Recent compliance history is the best predictor of future problems — the year-by-year record is below.
See the record ↓Ruskin's drinking water received a grade of D+ (50 out of 100), indicating poor water quality. The city's 17 water systems serve approximately 1,035 residents using groundwater.
Lead levels were measured at 0.0 ppb (90th percentile), well within EPA limits. This system has not yet been tested for PFAS under the EPA UCMR 5 program. The system has 533 violations on record, including 70 health-based violations. 69 remain unresolved.
Ruskin ranks #483 out of 513 cities in Michigan for water quality, placing it among the lowest-rated in the state. Ruskin relies on groundwater, which is generally less vulnerable to surface contamination but can be affected by naturally occurring minerals like arsenic and nitrate, as well as agricultural and industrial runoff. As a small community water system, Ruskin may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities. The system has seen 62 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.
02What's in Ruskin's water
Every contaminant flagged in Ruskin, on one shared scale: distance to its own legal limit. The red line is the limit — anything past it is out of compliance, and the closer a bar gets, the less headroom the system has.

03Ruskin's ten-year track record
Each box is one year. A green check means no EPA violations; a numbered badge counts that year's violations — red if any were health-based, amber if they were monitoring or paperwork issues. The system has 533 violations on record, including 70 health-based violations. 69 remain unresolved.
1 of the last ten years was clean. The numbered years had EPA violations — red when any were health-based, amber when they were paperwork or missed-testing issues.
▼ Down 8 ppb since 1993. Latest reading: 0 ppb (2025) — 0% of the action level. Sampled at higher-risk homes (90th percentile).
04Where Ruskin's water comes from
Ruskin's drinking water is drawn from underground aquifers through wells.
Groundwater
Underground aquifers reached by wells — naturally filtered, but can carry minerals like arsenic and nitrate.
Local treatment
Groundwater generally needs less treatment — typically disinfection and, where needed, mineral removal.
17 systems
17 water systems, operated under private ownership.
1,035 people
Residents served across Ruskin's service area.
Groundwater is naturally filtered through rock and soil layers, generally requiring less treatment than surface water. However, it can contain naturally occurring contaminants like arsenic, radon, and minerals. Agricultural activity, septic systems, and industrial operations near well fields can introduce nitrates, pesticides, and volatile organic compounds. The system is operated by private ownership and serves approximately 1,035 people through 17 water systems.

05Pressure on Ruskin's watershed
Outside forces that shape what reaches the treatment plant. None of these is a verdict on the tap by itself — but each adds pressure worth knowing about.
Flood & storm history
10 federal disaster declarations on record for Hillsborough County. Flooding and severe storms can overwhelm treatment plants, cause sewage overflows, and push runoff into supplies.
Drought
Hillsborough County is in D3 (extreme drought) per the U.S. Drought Monitor (week of Jul 2026). Drought can raise disinfection-byproduct levels and taste/odor issues as utilities draw from lower reservoirs.
