Share of listed systems, followed by the count, reported population, and funding in each status.
Points show reported system locations. They do not represent service-area boundaries.
Each point represents one system record.
Solano County has 26 public water systems in the SAFER dataset. Of these, 2 (8%) are classified as Failing or At-Risk.
Those systems report serving 89 people. The county profile is also shaped by small systems: 12 systems serve 500 people or fewer.
4 systems are Not Assessed. These fall outside the SAFER risk assessment, so they carry no classification either way.
Reported funding since 2017 totals $0 across 0 systems. Technical assistance funding totals $0.
Not Assessed systems make up 15% of listed systems and 74% 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.
