3 public water systems serve this ZIP code in the federal records. Everything below comes from EPA monitoring data, and everything missing is named.
SACRAMENTO SUBURBAN WATER DISTRICT
PWSID CA3410001 · CA · serves 194,444 people
PFAS and lithium
5 compounds detected at or above the reporting limit under EPA’s UCMR 5 monitoring, across 36 samples.
| Compound | Highest detected | Samples | Most recent |
|---|---|---|---|
| lithium | 60 µg/L | 25 | 6/5/2024 |
| PFPeA | 0.0071 µg/L | 5 | 7/16/2024 |
| PFHxS | 0.0058 µg/L | 1 | 7/16/2024 |
| PFHxA | 0.0057 µg/L | 4 | 7/16/2024 |
| PFBS | 0.0047 µg/L | 1 | 7/16/2024 |
A detection is a measurement, not a violation and not a health finding. EPA states that UCMR 5 results do not indicate compliance or non-compliance with any limit.
Health-based violations
No open health-based violation on record. This covers MCL, treatment technique and MRDL violations in SDWIS that have not been returned to compliance. It excludes monitoring and reporting violations, which are the large majority nationally, so this is not “no violations”, and SDWIS completeness varies by state.
Hardness
Median hardness 90 mg/L as CaCO₃, measured at 5 stations serving this system across 5 results, 2017-08-22 to 2020-07-07. Measured in the water source and distribution area, not at a tap, and not in your home.
CAL AM - LINCOLN OAKS
PWSID CA3410013 · CA · serves 48,094 people
PFAS and lithium
2 compounds detected at or above the reporting limit under EPA’s UCMR 5 monitoring, across 30 samples.
| Compound | Highest detected | Samples | Most recent |
|---|---|---|---|
| lithium | 87 µg/L | 29 | 9/18/2023 |
| PFHpA | 0.003 µg/L | 1 | 2/7/2023 |
A detection is a measurement, not a violation and not a health finding. EPA states that UCMR 5 results do not indicate compliance or non-compliance with any limit.
Health-based violations

It excludes monitoring and reporting violations, which are the large majority nationally, so this is not “no violations”, and SDWIS completeness varies by state.
Hardness
No hardness measurement. Hardness is measured at environmental monitoring stations, and none fell inside this system’s service area. That is a gap in where monitoring happens, not a finding about the water.

Median hardness 342 mg/L as CaCO₃, measured at 11 stations serving this system across 11 results, 2017-08-07 to 2020-07-07. Measured in the water source and distribution area, not at a tap, and not in your home.
What this report cannot tell you
Every figure describes water at a sampling point: a treatment plant, an entry point to the distribution system, or a monitoring station. None of it describes water arriving at your tap. Plumbing between the two can add lead and copper, and if your home was built before 1986 a test kit tells you something no federal dataset can.
