The concern

Copper is over its legal limit

Measured at 2.95 mg/L against the EPA Action Level of 1.3 mg/L. The ledger below shows how far over — and which filter removes it.

The good news

Lead is well under the limit

90th-percentile lead is 2.2 ppb — beneath the 15 ppb federal action level and under the 5 ppb watch threshold.

Gattman's drinking water received a grade of B (75.6 out of 100), indicating good water quality. The city's 1 water system serves approximately 790 residents using groundwater.

Lead levels were measured at 2.2 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 105 violations on record, including 4 health-based violations. 6 remain unresolved.

Gattman ranks #141 out of 319 cities in Mississippi for water quality, placing it mid-range in the state. Gattman 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, Gattman may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities. The system has seen 7 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.

02What's in Gattman's water

Every contaminant flagged in Gattman, 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.

Over Limit — EPA Action Level: 1.3 mg/L

Exceeds the EPA action level. Copper leaches from household plumbing — flush taps for 30 seconds before drinking, and consider a certified filter.

04Where Gattman's water comes from

Gattman's drinking water is drawn from underground aquifers through wells.

Source

Groundwater

Underground aquifers reached by wells — naturally filtered, but can carry minerals like arsenic and nitrate.

Treatment

Local treatment

Groundwater generally needs less treatment — typically disinfection and, where needed, mineral removal.

Distribution

1 system

1 water system, operated under local government ownership.

Delivery

790 people

Residents served across Gattman'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 790 people through 1 water system.
