Summary

San Bernardino County has 152 public water systems in the SAFER dataset. Of these, 47 (31%) are classified as Failing or At-Risk.

Those systems report serving 373,774 people. The county profile is also shaped by small systems: 61 systems serve 500 people or fewer.

14 systems are listed as Not Assessed, serving 1,410,226 people, so Not Assessed should not be read as a low-risk classification.

Reported funding since 2017 totals $151M across 19 systems. Technical assistance funding totals $7M.

System counts and reported population

Not Assessed systems make up 9% of listed systems and 57% of reported population. That population sits in a few large systems outside the SAFER assessment’s scope, which generally have more capacity, so this reflects scope rather than hidden risk.

Risk profile

Risk in San Bernardino County is distributed across four dimensions. Water Quality contributes the largest share of the combined weighted risk score at 37%. Across all individual indicators, Household socioeconomic burden appears most often, affecting 103 of 138 assessed systems.

Patterns and context

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 152 systems in San Bernardino County.

Status by system size

SAFER status within each population group

Among systems serving 500 people or fewer, 24 of 61 are Failing or At-Risk. This size group has the county’s highest concentration of high-concern classifications.

Economic context
