See the risk factors ↓Hartland's drinking water received a grade of A (94.7 out of 100), indicating excellent water quality. The city's 1 water system serves approximately 3,022 residents using groundwater.
Lead levels were measured at 5.0 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 2 violations on record, including 0 health-based violations. All violations have been resolved.
Hartland ranks #25 out of 513 cities in Michigan for water quality, placing it one of the best in the state. Hartland 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, Hartland may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities.
02What's in Hartland's water
Every contaminant flagged in Hartland, 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.

03Hartland'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 2 violations on record, including 0 health-based violations. All violations have been resolved.
All ten of the last ten years were clean — no EPA violations recorded for Hartland.
▲ Up 4 ppb since 2019. Latest reading: 5 ppb (2022) — 33% of the action level. Sampled at higher-risk homes (90th percentile).
04Where Hartland's water comes from
Hartland'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.
1 system
1 water system, operated under local government ownership.
3,022 people
Residents served across Hartland'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 local government ownership and serves approximately 3,022 people through 1 water system.

05Pressure on Hartland'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.
Industrial discharge
5 facilities within 10 miles reported 0 lb released to surface water in the latest EPA Toxics Release Inventory. Proximity doesn't equal tap contamination — treatment and hydrology decide — but it's pressure on the watershed.
Flood & storm history
3 federal disaster declarations on record for Livingston County. Flooding and severe storms can overwhelm treatment plants, cause sewage overflows, and push runoff into supplies.
Superfund proximity
2 National Priorities List sites within 10 miles. Proximity does not necessarily indicate tap-water contamination — the connection depends on hydrology and treatment.

07What to do at home
Steps matched to what testing actually found in Hartland's water — not generic advice.
A basic carbon filter still helps
Hartland's water meets federal standards, but a simple carbon filter improves taste and adds a margin of safety against short-term issues.
Compare tested filters →Flush taps & check your service line
Lead leaches from pipes as water sits. Run cold water 30 seconds before drinking (especially mornings), and ask the utility whether your address still has a lead service line.
