See the ledger ↓Andrews's drinking water received a grade of D (49.5 out of 100), indicating poor water quality. The city's 1 water system serves approximately 1,149 residents using groundwater.
Lead levels were measured at 11.5 ppb (90th percentile), which is within EPA limits but above recommended levels. This system has not yet been tested for PFAS under the EPA UCMR 5 program. The system has 70 violations on record, including 2 health-based violations. 12 remain unresolved.
Andrews ranks #379 out of 402 cities in Indiana for water quality, placing it among the lowest-rated in the state. Andrews 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. While lead levels are within EPA limits, they are above the recommended 5 ppb threshold that health organizations consider ideal. A point-of-use filter adds an extra layer of protection. As a small community water system, Andrews may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities. The system has seen 29 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.
02What's in Andrews's water
Every contaminant flagged in Andrews, 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.
Near Limit — EPA Action Level: 15 ppb
Within EPA limits but above the American Academy of Pediatrics recommended level of 1 ppb — no lead level is considered safe for children. An NSF 53-certified filter provides additional protection, and running the cold tap 30 seconds after stagnation reduces exposure.Full contaminants report

03Andrews'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 70 violations on record, including 2 health-based violations. 12 remain unresolved.
7 of the last ten years were clean. The numbered years had EPA violations — red when any were health-based, amber when they were paperwork or missed-testing issues.
▲ Up 7.5 ppb since 1993. Latest reading: 12 ppb (2024) — 77% of the action level. Sampled at higher-risk homes (90th percentile).
04Where Andrews's water comes from
Andrews'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.
1,149 people
Residents served across Andrews'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 1,149 people through 1 water system.

05Pressure on Andrews'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 3 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
2 federal disaster declarations on record for Huntington County. Flooding and severe storms can overwhelm treatment plants, cause sewage overflows, and push runoff into supplies.

Filter drinking & cooking water
NSF-certified water filter. Lead detected at 11.5 ppb
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.
