waterverge.com Blairsville, PA — Water Quality Report
Blairsville's drinking water received a grade of F (37.4 out of 100), indicating failing water quality. The city's 3 water systems serve approximately 20,113 residents using surface water.
Lead levels were measured at 7.2 ppb (90th percentile), which is within EPA limits but above recommended levels. UCMR 5 testing detected 6 PFAS compounds, with levels exceeding EPA maximum contaminant levels in the water supply.
The system has 630 violations on record, including 22 health-based violations. 30 remain unresolved.
What to know about Blairsville's water
Blairsville ranks #473 out of 560 cities in Pennsylvania for water quality, placing it among the lowest-rated in the state.
The city draws from surface water sources, which are more susceptible to seasonal runoff and agricultural contamination, requiring extensive multi-barrier treatment including coagulation, filtration, and disinfection.
Of particular concern: PFAS "forever chemical" levels exceed the 2024 EPA maximum contaminant levels. These synthetic compounds don't break down naturally and require specialized filtration such as reverse osmosis or granular activated carbon.
Haloacetic acid (HAA5) levels were elevated at 33.0 µg/L in UCMR 4 testing, though below the 60 µg/L EPA limit. Activated carbon filtration can help reduce these disinfection byproducts.
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.
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.
The system has seen 68 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.

Why does Blairsville have so many PFAS compounds in its water?
6 different PFAS "forever chemical" compounds were detected in Blairsville's water supply during UCMR 5 testing. PFAS contamination often originates from proximity to military installations (AFFF firefighting foam), airports, industrial manufacturing sites, or wastewater treatment facilities. Some levels exceed the 2024 EPA maximum contaminant levels — a reverse osmosis or NSF-certified activated carbon filter is strongly recommended.
How does Blairsville's water compare to other cities?
Blairsville ranks #473 out of 560 cities in Pennsylvania (better than 16% of state cities) and #15413 out of 15744 cities nationally (2th percentile). The grade of F reflects the combined assessment of violation history, lead and copper levels, PFAS contamination, and regulatory compliance.
