01The verdict: is Snow Hill water safe?
Snow Hill's drinking water has significant quality concerns based on EPA testing data. With a grade of B+ (84.7/100), the system has issues across multiple categories. A water filter is recommended for all residents. The city's 1 water system serves approximately 2,409 residents using groundwater (wells).

See the record ↓Snow Hill's drinking water received a grade of B+ (84.7 out of 100), indicating good water quality. The city's 1 water system serves approximately 2,409 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 30 violations on record, including 4 health-based violations. 3 remain unresolved.
Snow Hill ranks #32 out of 107 cities in Maryland for water quality, placing it mid-range in the state. Snow Hill 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. Hexavalent chromium (chromium-6) was detected at 0.06 µg/L in UCMR 3 testing. While below California's 10 µg/L limit and with no federal MCL set, residents sensitive to this contaminant may consider reverse osmosis filtration. As a small community water system, Snow Hill may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities.
02What's in Snow Hill's water
Every contaminant flagged in Snow Hill, 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.

03Snow Hill'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 30 violations on record, including 4 health-based violations. 3 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.
▼ Down 5 ppb since 1996. Latest reading: 0 ppb (2023) — 0% of the action level. Sampled at higher-risk homes (90th percentile).
04Where Snow Hill's water comes from
Snow Hill'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.
2,409 people
Residents served across Snow Hill'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 2,409 people through 1 water system.

These water bodies shape the regional watershed and can indirectly affect groundwater quality.
05Pressure on Snow Hill'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
1 facility 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
7 federal disaster declarations on record for Worcester County. Flooding and severe storms can overwhelm treatment plants, cause sewage overflows, and push runoff into supplies.
Drought
Worcester County is in D2 (severe 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.
