Summary

El Dorado County has 23 public water systems in the SAFER dataset. Of these, 6 (26%) are classified as Failing or At-Risk.

Those systems report serving 584 people. The county profile is also shaped by small systems: 13 systems serve 500 people or fewer.

1 system is listed as Not Assessed, serving 132,171 people, so Not Assessed should not be read as a low-risk classification.

Reported funding since 2017 totals $32M across 4 systems. Technical assistance funding totals $35K.

System counts and reported population

Not Assessed systems make up 4% of listed systems and 52% 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.
