Analysis

What to know about Sacramento's water

Sacramento ranks #693 out of 694 cities in California 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.

Hexavalent chromium (chromium-6) was detected at 14.81 µg/L, above California's 10 µg/L limit. There is no federal MCL, but the EPA is reviewing evidence linking long-term exposure to cancer risk.

As a major metropolitan system serving over 1.2M residents, Sacramento faces large-scale infrastructure challenges including aging pipes and the complexity of treating water across a vast distribution network.

The system has seen 150 violations in the past five years, suggesting a pattern of compliance challenges that residents should monitor closely.

Key contaminant findings

Based on the most recent EPA sampling data for Sacramento's water supply.

Lead Within Limits
Detected: 0.0 ppb Limit: 15 ppb (EPA Action Level)

Well within EPA limits.

Copper Exceeds Limit
Detected: 1.45 mg/L Limit: 1.3 mg/L (EPA Action Level)

Exceeds EPA action level. Copper can leach from household plumbing — flush taps for 30 seconds before drinking.

PFAS (9 compounds) Elevated
Detected: Highest: lithium at 474.0000 µg/L Limit: 0.004 µg/L (EPA MCL)

PFAS "forever chemicals" exceed EPA maximum contaminant levels. Reverse osmosis or granular activated carbon filtration strongly recommended.

Chromium-6 (Hexavalent Chromium) Exceeds Limit
Detected: 14.81 µg/L Limit: 10 µg/L (California MCL — no federal limit)

The "Erin Brockovich" chemical. There is no federal MCL, but California has set a limit of 10 µg/L. Reverse osmosis filtration is effective at removing hexavalent chromium.

PFAS "forever chemicals" detected

UCMR 5 testing found 9 PFAS compounds in Sacramento's water supply. PFAS are synthetic chemicals that persist indefinitely in the environment and the human body.

Where Sacramento's water comes from

Surface Water

Sacramento's drinking water comes primarily from surface water sources such as rivers, lakes, or reservoirs.

Surface water systems require multi-stage treatment including coagulation, sedimentation, filtration, and disinfection to meet EPA Safe Drinking Water Act standards.

These sources can be impacted by seasonal changes, stormwater runoff, upstream agriculture, and industrial discharge.

The system is operated by state ownership and serves approximately 1,223,407 people through 77 water systems.

Frequently asked questions

Is Sacramento, CA tap water safe to drink?

Sacramento's water quality earned a grade of F (31.2/100). Significant issues have been found. A water filter is strongly recommended. The city ranks #693 out of 694 cities tested in California.

What contaminants are in Sacramento's water?

Lead was measured at 0.0 ppb (90th percentile). 9 PFAS compounds were detected. 1263 violations are on record.

How is Sacramento'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 Sacramento?

PFAS compounds exceed EPA limits — a reverse osmosis or activated carbon filter is recommended.

Where does Sacramento's water come from?

Sacramento's water is sourced from Surface water. The city has 77 water systems serving approximately 1,223,407 residents.

What health violations has Sacramento's water system had?

Sacramento has 425 health-based violations on record. The most recent violation was recorded in November 2025. Health-based violations mean the water exceeded EPA maximum contaminant levels (MCLs) for a regulated substance. 199 violations remain unresolved.

Why does Sacramento have so many PFAS compounds in its water?

9 different PFAS "forever chemical" compounds were detected in Sacramento'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 Sacramento's water compare to other cities?

Sacramento ranks #693 out of 694 cities in California (better than 0% of state cities) and #15653 out of 15744 cities nationally (1th percentile). The grade of F reflects the combined assessment of violation history, lead and copper levels, PFAS contamination, and regulatory compliance.
