PFAS and Toxin Reduction Water Filtration in San Diego.

PFAS — per- and polyfluoroalkyl substances — are synthetic chemicals detected in San Diego’s water supply, particularly in areas near military installations. They do not break down in the environment or in the body. Reverse osmosis removes up to 99% of PFAS. Here is what San Diego homeowners need to know.

•    Why San Diego Specifically    •

PFAS in San Diego

PFAS have been detected near Camp Pendleton, Marine Corps Air Station Miramar, and other military sites in San Diego County, where fire-fighting foam was historically used in training.

Southern California has one of the highest concentrations of PFAS
detections in the nation, with over 200 water systems showing measurable levels at some point in the past decade.

San Diego’s municipal water meets current legal standards — but legal and ideal are not the same number, particularly for PFAS where regulatory limits are still being established.

Other Toxins of Note

PFAS get the headlines, but they aren’t the only contaminants worth understanding in San Diego’s water.

0.36 ppb

Chromium-6

Detected in San Diego water — roughly 18x above levels many researchers consider safe. The EPA does not currently regulate chromium-6 specifically.

TTHMs & HAA5

Disinfection Byproducts
Chloramine reacting with organic matter produces TTHMs and HAA5 compounds, both associated with long-term health concerns at sustained exposure levels.

2 ppb

Arsenic
Detected in San Diego — below the EPA limit but above the 1 ppb level often recommended for homes with children.

Which Systems Remove PFAS

Not all filtration is equal. Here’s an honest comparison.

Reverse Osmosis

Detected in San Diego water — roughly 18x above levels many researchers consider safe. The EPA does not currently regulate chromium-6 specifically.
Most Effective

Whole-House Activated Carbon

Reduces PFAS, but effectiveness varies by system design and contaminant type. Useful for whole-home reduction when paired with RO at the tap.
Varies

Standard Pitcher Filters

Most standard pitcher filters do NOT effectively remove PFAS. Don’t rely on them for protection from these specific contaminants.
Not Recommended
•   Geography     •

Higher-Concern Areas

Oceanside, Carlsbad, Poway, and areas near MCAS Miramar and Camp Pendleton have received the most attention from regulators regarding PFAS.
