230 people served. No health-based SDWIS violations recorded in the past 5 years. Last cited 2 years ago.
No SDWIS health-based or unresolved violations on the record. Contaminant detail and equity context below.
Health-based violations exceed an MCL or treatment-technique standard. Monitoring violations are reporting failures with no measured exceedance — they tell you the system isn't fully transparent, not that the water is unsafe today.

What this is not. SDWIS records compliance against federal MCLs — not a direct readout of tap-water concentrations. Active health-based violations are not the same as a current crisis; we link to the EPA record so you can verify return-to-compliance status before forming a conclusion.
