What the EPA has on record, by system
Sheffield Utilities, City Of Sheffield
13,758 served · surface water · PWSID AL0000327 - Health-based TTHM: a health-based violation (a contaminant recorded above the limit the EPA tracks), recorded 5 times between April 2025 and July 2025. The EPA record lists a level of 0.081 MG/L; the limit (MCL) is 0.08 MG/L. EPA records do not show all of these as returned to compliance.
- Monitoring LASSO: a monitoring or reporting violation (a required test or report was late or missed — not a measured exceedance), recorded 4 times in January 2020. 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.
