01The verdict: is Brunswick water safe?
Brunswick's drinking water has significant quality concerns based on EPA testing data. With a grade of B+ (81/100), the system has issues across multiple categories. A water filter is recommended for all residents. The city's 3 water systems serve approximately 576 residents using groundwater (wells).
18 unresolved violations on record
EPA records show open compliance items for this system. Most are administrative, but unresolved items are worth watching.
See what was cited ↓Lead is well under the limit
90th-percentile lead is 3.0 ppb — beneath the 15 ppb federal action level and under the 5 ppb watch threshold.
See the trend ↓3 violations in the last five years
Recent compliance history is the best predictor of future problems — the year-by-year record is below.
See the record ↓Brunswick's drinking water received a grade of B+ (81 out of 100), indicating good water quality. The city's 3 water systems serve approximately 576 residents using groundwater.
Lead levels were measured at 3.0 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 104 violations on record, including 1 health-based violation. 18 remain unresolved.
Brunswick ranks #135 out of 400 cities in North Carolina for water quality, placing it mid-range in the state. Brunswick 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, Brunswick may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities.
02What's in Brunswick's water
Every contaminant flagged in Brunswick, 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.

03Brunswick'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 104 violations on record, including 1 health-based violation. 18 remain unresolved.
4 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 1.8 ppb since 2009. Latest reading: 3 ppb (2025) — 20% of the action level. Sampled at higher-risk homes (90th percentile).
04Where Brunswick's water comes from
Brunswick'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.
3 systems
3 water systems, operated under local government ownership.
576 people
Residents served across Brunswick'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 576 people through 3 water systems.

05Pressure on Brunswick'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
2 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
10 federal disaster declarations on record for Columbus County. Flooding and severe storms can overwhelm treatment plants, cause sewage overflows, and push runoff into supplies.
Drought
Columbus County is in D4 (exceptional 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.
