Shasta County has 72 public water systems in the SAFER dataset. Of these, 13 (18%) are classified as Failing or At-Risk.
Those systems report serving 6,233 people. The county profile is also shaped by small systems: 55 systems serve 500 people or fewer.
3 systems are Not Assessed. These fall outside the SAFER risk assessment, so they carry no classification either way.
Reported funding since 2017 totals $43M across 14 systems. Technical assistance funding totals $4M.
Not Assessed systems make up 4% of listed systems and 52% of reported population. A few large systems account for most of that population, so a small number of systems can shift the population picture entirely. Counts and population are worth reading together.
Risk in Shasta County is distributed across four dimensions. Accessibility contributes the largest share of the combined weighted risk score at 52%. Across all individual indicators, No intertie appears most often, affecting 68 of 69 assessed systems.
Water Quality accounts for 13% of the county’s combined weighted risk score. Emerging contaminants appears in 11 of 69 assessed systems. Water quality trends toward MCL is next, appearing in 4 of 69 assessed systems.
Accessibility accounts for 52% of the county’s combined weighted risk score. No intertie appears in 68 of 69 assessed systems. Limited water sources is next, appearing in 41 of 69 assessed systems.

TMF Capacity accounts for 18% of the county’s combined weighted risk score. Total net annual income appears in 33 of 69 assessed systems. Operating ratio is next, appearing in 24 of 69 assessed systems.
The countywide totals hide important differences among systems. The panels below show how SAFER status varies by system size and service-area economic status, what conditions appear among Failing systems, and how reported funding is distributed across the 72 systems in Shasta County.
SAFER status within each population group
Among systems serving 500 people or fewer, 10 of 55 are Failing or At-Risk. The highest concentration occurs among systems serving 501 to 3,300, at 30%.
Orange shows Failing or At-Risk systems within each service-area group
DAC and SDAC service areas contain 35 of 72 listed systems. Within those two groups, 7 systems are Failing or At-Risk.
A system can appear under more than one condition
No primary analytes were listed for Failing systems.
Among 2 Failing systems, 1 report secondary MCL violation. No primary analytes are listed for these systems.
Totals since 2017 and number of systems reporting funding
Funding since 2017 totals $43M across 14 systems. Not At-Risk systems account for 92% of that total. Reported technical assistance funding adds $4M.
That represents 13 systems reporting service to 6,233 people. That is below the statewide average of 33%.
The most widespread individual flag is no intertie, found in 68 of 69 assessed systems. Statewide, Accessibility accounts for 36% of weighted risk.
Small systems account for 55 of the county’s 72 listed systems. That is above the statewide average of 63%.
