See the risk factors ↓Point Reyes Station's drinking water received a grade of A- (86.7 out of 100), indicating good water quality. The city's 1 water system serves approximately 1,560 residents using groundwater.
Lead levels were measured at 8.0 ppb (90th percentile), which is within EPA limits but above recommended levels. This system has not yet been tested for PFAS under the EPA UCMR 5 program. The system has 38 violations on record, including 0 health-based violations. 1 remains unresolved.
Point Reyes Station ranks #224 out of 690 cities in California for water quality, placing it mid-range in the state. Point Reyes Station relies on groundwater, which is generally less vulnerable to surface contamination but can be affected by naturally occurring minerals like arsenic and nitrate, as well as agricultural and industrial runoff. 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. As a small community water system, Point Reyes Station may have fewer resources for advanced treatment technologies and infrastructure upgrades compared to larger utilities.
02What's in Point Reyes Station's water
Every contaminant flagged in Point Reyes Station, on one shared scale: distance to its own legal limit. The red line is the limit — anything past it is out of compliance, and the closer a bar gets, the less headroom the system has.
Over Limit — EPA Action Level: 1.3 mg/L
Exceeds the EPA action level. Copper leaches from household plumbing — flush taps for 30 seconds before drinking, and consider a certified filter.Full contaminants report

03Point Reyes Station's ten-year track record
Each box is one year. A green check means no EPA violations; a numbered badge counts that year's violations — red if any were health-based, amber if they were monitoring or paperwork issues. The system has 38 violations on record, including 0 health-based violations. 1 remains unresolved.
8 of the last ten years were clean. The numbered years had EPA violations — red when any were health-based, amber when they were paperwork or missed-testing issues.
▲ Up 8 ppb since 2004. Latest reading: 8 ppb (2021) — 53% of the action level. Sampled at higher-risk homes (90th percentile).
▲ Up 0.19 mg/L since 2004. The latest reading (1.8 mg/L, 2009) is over the action level. Sampled at higher-risk homes (90th percentile).
04Where Point Reyes Station's water comes from
Point Reyes Station's drinking water is drawn from underground aquifers through wells.
Groundwater
Underground aquifers reached by wells — naturally filtered, but can carry minerals like arsenic and nitrate.
Local treatment
Groundwater generally needs less treatment — typically disinfection and, where needed, mineral removal.
1 system
1 water system, operated under federal ownership.
1,560 people
Residents served across Point Reyes Station's service area.
Groundwater is naturally filtered through rock and soil layers, generally requiring less treatment than surface water. However, it can contain naturally occurring contaminants like arsenic, radon, and minerals. Agricultural activity, septic systems, and industrial operations near well fields can introduce nitrates, pesticides, and volatile organic compounds. The system is operated by federal ownership and serves approximately 1,560 people through 1 water system.
