waterverge.com Santa Fe Springs, CA — Water Quality Report
Santa Fe Springs's drinking water received a grade of B+ (80.4 out of 100), indicating good water quality. The city's 2 water systems serve approximately 57,432 residents using purchased surface water.
Lead levels were measured at 5.6 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 8 violations on record, including 1 health-based violation. 3 remain unresolved.
What to know about Santa Fe Springs's water
Santa Fe Springs ranks #363 out of 694 cities in California for water quality, placing it below average 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 3.20 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.
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.

What Santa Fe Springs residents can do
Recommended: Reverse osmosis system. This addresses the specific contaminants found in Santa Fe Springs'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.
Santa Fe Springs's area has a history of flooding. After severe weather, watch for boil water advisories from your local utility.

What health violations has Santa Fe Springs's water system had?
Santa Fe Springs has 1 health-based violation on record. The most recent violation was recorded in October 2019. Health-based violations mean the water exceeded EPA maximum contaminant levels (MCLs) for a regulated substance. 3 violations remain unresolved.
Why does Santa Fe Springs have so many PFAS compounds in its water?
6 different PFAS "forever chemical" compounds were detected in Santa Fe Springs'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.
