Nothing open that measures the water, but 1 open testing or paperwork violation.

A missed test is not evidence of bad water. It also is not evidence of good water: for that period nobody checked.

On record since 1992: 232 violations. 15 over the limit · 28 treatment lapses · 186 missed or late tests · 3 notices or reports. Most recent began 2024-01-01.

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

More violations on record than 99% of active water systems in Puerto Rico. Small systems with no staff chemist often rack up missed-test violations; big utilities rarely do.

One square ≈ 7 violations (rounded up), by the year they began. Empty columns are years with nothing on EPA's record.
6% over the limit · 1512% treatment lapse · 2880% missed or late test · 1861% notice or report · 3

Across Puerto Rico, 83% of violations are missed or late tests and 9% are water over a limit.

Each dot is one over-the-limit violation: the measured value divided by the limit it broke, on a log scale. Most legal limits for chemicals are running averages set for a lifetime of drinking, so “just over” and “ten times over” are very different news. Hover a dot for the numbers.

    Reading this record

    Ponce Urbano is a community water system that draws from surface water and serves about 111,926 people in Ponce, 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.
