1 open treatment violation.

Open for: Lead service line inventory. EPA counts treatment-technique violations as health-based: a required protective step was not done. It is not a measurement of contamination.

On record since 2013: 12 violations. 2 over the limit · 1 treatment lapse · 8 missed or late tests · 1 notice or report. Most recent began 2024-10-17.

For this year's test results, ask the utility for its annual Consumer Confidence Report. Every community system must publish one.

Reading this record

Acued.Comunal Sect. Manuel Diaz is a community water system that draws from groundwater and serves about 331 people in San Lorenzo, Puerto Rico. Everything above comes from the EPA's Safe Drinking Water Information System (SDWIS), where states report every violation by every public water system.

Four kinds of violation. Only one is a measurement of the water: over the limit means a test came back above a legal maximum (an MCL). A treatment lapse means a required protective step was not done, such as disinfection, filtration, fixing a defect an inspector found, or filing a lead-pipe inventory. A missed or late test means a required test was skipped or never reported. That is the most common kind, and the most misread: it does not mean the water was bad, and it does not mean the water was fine. Notices and reports covers public notices and the annual Consumer Confidence Report.

Status. “Back in compliance” means the state recorded a return to compliance. “Period ended” means the violation's compliance period is over but no return to compliance was ever filed, which is common in older records. EPA's federal copy lags state records by months, so call the utility for anything current.
