43.6/100
Salem, OR — Water Quality Report
Salem's drinking water received a grade of F (43.6 out of 100), indicating failing water quality. The city's 27 water systems serve approximately 217,487 residents using surface water.
Lead levels were measured at 0.0 ppb (90th percentile), well within EPA limits. PFAS testing under UCMR 5 found no detectable forever chemicals.
The system has 3309 violations on record, including 108 health-based violations. 360 remain unresolved.
What to know about Salem's water
Salem ranks #175 out of 213 cities in Oregon 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.
Haloacetic acid (HAA5) levels were elevated at 31.3 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 0.10 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.
The system has seen 359 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.
