29.4/100
Medford, OR — Water Quality Report
Medford's drinking water received a grade of F (29.4 out of 100), indicating failing water quality. The city's 14 water systems serve approximately 106,994 residents using surface water.
Lead levels were measured at 44.2 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 604 violations on record, including 44 health-based violations. 84 remain unresolved.
What to know about Medford's water
Medford ranks #211 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 0.20 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 144 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.

Where does Medford's water come from?
Medford's drinking water comes from surface water (rivers, lakes, or reservoirs), supplied by 14 water systems serving approximately 106,994 people. Surface water sources are more susceptible to contamination from runoff, industrial discharge, and algal blooms, requiring extensive treatment. Nearby water bodies include Bear Creek Below Ashland Creek (river), Bear Creek (river), Rogue River (river), Little Applegate River (river).
What Medford residents can do
Recommended: NSF 53-certified pitcher or under-sink filter. This addresses the specific contaminants found in Medford'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.
Medford's area has a history of flooding. After severe weather, watch for boil water advisories from your local utility.
