Farmington has no town government of its own, so San Joaquin County runs its elections and most services, and its children attend Escalon Unified School District. Tap water in most of Farmington comes from Farmington Water Company, which has a clean five-year EPA record (about 23% of systems its size had a health-based violation) and a latest lead result below detection.

No health-based violations reported to EPA in the five years to October 2026, like 77% of the 15,074 systems serving 101–500 people.
The latest lead result on file, the 90th percentile of homes sampled in Jan 2023–Dec 2025, was 0.0 ppb, below the 15 ppb action level that applied. Results below detection are reported as 0, so 0 doesn’t mean no lead at any tap.
