waterverge.com Eugene, OR — Water Quality Report
Eugene's drinking water received a grade of F (28 out of 100), indicating failing water quality. The city's 34 water systems serve approximately 179,954 residents using surface water.
Lead levels were measured at 25.9 ppb (90th percentile), which exceeds the EPA action level of 15 ppb. PFAS testing under UCMR 5 found no detectable forever chemicals.
The system has 2141 violations on record, including 178 health-based violations. 342 remain unresolved.
What to know about Eugene's water
Eugene ranks #213 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.
Hexavalent chromium (chromium-6) was detected at 0.12 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.
Lead levels exceed the EPA action level of 15 ppb, which typically indicates aging lead service lines or lead solder in the distribution system. An NSF 53-certified filter is strongly recommended for drinking and cooking water.
The system has seen 205 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.

Flood & environmental risk
Lane County has experienced 7 federally declared disasters since 1964. Flooding and severe storms can overwhelm water treatment plants, cause sewage overflows, and introduce agricultural runoff, bacteria, and sediment into drinking water supplies. Local water sources include Coast Fork Willamette River, Willamette River, Mckenzie River, Mohawk River, Mckenzie River.
Where does Eugene's water come from?
Eugene's drinking water comes from surface water (rivers, lakes, or reservoirs), supplied by 34 water systems serving approximately 179,954 people. Surface water sources are more susceptible to contamination from runoff, industrial discharge, and algal blooms, requiring extensive treatment. Nearby water bodies include Coast Fork Willamette River (river), Willamette River (river), Mckenzie River (river), Mohawk River (river), Mckenzie River (river).
What Eugene residents can do
Recommended: NSF 53-certified pitcher or under-sink filter. This addresses the specific contaminants found in Eugene's water.
Your water utility is required to publish an annual Consumer Confidence Report (CCR) with detailed testing results. Ask for the latest copy or check your utility's website.
Run cold water for 30 seconds before drinking, especially in the morning. Lead and copper leach from household plumbing when water sits in pipes.
Eugene's area has a history of flooding. After severe weather, watch for boil water advisories from your local utility.

What contaminants are in Eugene's water?
Lead was measured at 25.9 ppb (90th percentile). No PFAS compounds were detected. 2141 violations are on record.
How is Eugene's water quality grade calculated?
The grade is based on four factors: violation history (40%), lead and copper levels (25%), PFAS contamination (25%), and regulatory compliance (10%). The score is also adjusted based on how complete the available data is. See our methodology page for full details.
Do I need a water filter in Eugene?
Yes — lead levels exceed the EPA action level of 15 ppb. We recommend an NSF 53-certified filter or reverse osmosis system. Based on current data, basic filtration should suffice for additional peace of mind.
