01The verdict: is Summit Hill water safe?
Summit Hill's drinking water has significant quality concerns based on EPA testing data. With a grade of B- (70.7/100), the system has issues across multiple categories. A water filter is recommended for all residents. The city's 1 water system serves approximately 2,890 residents using groundwater (wells).
Copper is over its legal limit
Measured at 3.21 mg/L against the EPA Action Level of 1.3 mg/L. The ledger below shows how far over — and which filter removes it.

Measured at 13.0 ppb — 87% of the 15 ppb limit. Within the rules, but with less headroom than you'd want.
See the ledger ↓Summit Hill's drinking water received a grade of B- (70.7 out of 100), indicating fair water quality. The city's 1 water system serves approximately 2,890 residents using groundwater.
Lead levels were measured at 13.0 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 29 violations on record, including 1 health-based violation. 5 remain unresolved.
Summit Hill ranks #180 out of 559 cities in Pennsylvania for water quality, placing it mid-range in the state. Summit 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. 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, Summit Hill 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 Summit Hill's water
Every contaminant flagged in Summit 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.
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.Full contaminants report

03Summit 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 29 violations on record, including 1 health-based violation. 5 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.

▼ Down 0.96 mg/L since 1993. The latest reading (3.2 mg/L, 1997) is over the action level. Sampled at higher-risk homes (90th percentile).
04Where Summit Hill's water comes from
Summit 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.
2,890 people
Residents served across Summit 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 2,890 people through 1 water system.

Water bodies near Summit Hill
These water bodies shape the regional watershed and can indirectly affect groundwater quality.
05Pressure on Summit 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
5 facilities within 10 miles reported 677 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
8 federal disaster declarations on record for Carbon 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 Summit Hill's water — not generic advice.
Filter drinking & cooking water
NSF-certified water filter. Lead detected at 13.0 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.
