COAMO URBANO Water System
Consumer Confidence Report status
COAMO URBANO must publish a Consumer Confidence Report — the annual drinking water quality report covering calendar year 2026 — by July 1, 2027.
As of August 1, 2026, EPA's federal records show no open violations for COAMO URBANO.
Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed August 1, 2026. This is a record-keeping and public-information tool — it does not replace Puerto Rico’s official records. Always confirm current status with Puerto Rico before making decisions based on this information.

COAMO URBANO is one of 71 community water systems in Puerto Rico in the 3,301 to 10,000 people size category, serving 4,603 people from surface water.
As of August 1, 2026, its federal record holds 70 entries between 1983 and 2019, all of which EPA lists as closed. Nothing has been added since 2019.
Of the 70, 55 are monitoring and reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset — rather than findings about the water itself. The record involves the Surface Water Treatment Rules, volatile organic chemicals, and the Total Coliform Rules.

Common questions
Is COAMO URBANO required to publish a Consumer Confidence Report?
- Yes. COAMO URBANO is a community water system, and federal rules (40 CFR 141 Subpart O) require every community water system to publish a Consumer Confidence Report each year.
When is COAMO URBANO’s next Consumer Confidence Report due?
- COAMO URBANO’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does COAMO URBANO have any open drinking water violations on record?
- As of August 1, 2026, EPA's federal records show no open violations for COAMO URBANO.
What is a Consumer Confidence Report?
- A Consumer Confidence Report (CCR) is the annual drinking water quality report that community water systems must provide to the people they serve. It lists the contaminants detected in the system’s water during the year, where the water comes from, and how the results compare with federal limits. EPA’s revised CCR rule takes effect January 1, 2027, and the first reports in the new format are due July 1, 2027.
