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.
RIO LINDA/ELVERTA COMMUNITY WATER DIST
PWSID CA3410018 · CA · serves 15,460 people
PFAS and lithium
3 compounds detected at or above the reporting limit under EPA’s UCMR 5 monitoring, across 5 samples.
| Compound | Highest detected | Samples | Most recent |
|---|---|---|---|
| lithium | 13 µg/L | 2 | 5/22/2024 |
| PFHxA | 0.0048 µg/L | 1 | 11/6/2024 |
| PFHxS | 0.004 µg/L | 2 | 11/6/2024 |

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
Too few readings to state a hardness. 1 station(s), 1 result(s). Below two stations and five results this page will not state a number: a median of two readings from one creek is not your water.

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.
