What the EPA has on record, by system
San Lucas County Water District
315 served · groundwater · PWSID CA2701676 - Health-based Nitrate: a health-based violation (a contaminant recorded above the limit the EPA tracks), recorded 6 times between July 2016 and October 2021. The EPA record lists a level of 17 MG/L; the limit (MCL) is 10 MG/L. EPA records do not show all of these as returned to compliance.
- Monitoring TTHM: a monitoring or reporting violation (a required test or report was late or missed — not a measured exceedance), recorded 4 times between July 2023 and July 2024. EPA records do not show all of these as returned to compliance.
What this means
A health-based violation means a contaminant was recorded above the limit the EPA tracks for it. A monitoring or reporting violation means a required test or report was late or missed — not that a contaminant was measured above a limit. “Returned to compliance” means the EPA recorded the issue as resolved.
