Summary
Marin County has 18 public water systems in the SAFER dataset. Of these, 2 (11%) are classified as Failing or At-Risk.
Those systems report serving 1,973 people. The county profile is also shaped by small systems: 11 systems serve 500 people or fewer.
2 systems are Not Assessed. These fall outside the SAFER risk assessment, so they carry no classification either way.
Reported funding since 2017 totals $2M across 3 systems. Technical assistance funding totals $33K.
System counts and reported population
Not Assessed systems make up 11% of listed systems and 73% 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.
