COCOS Water System
Consumer Confidence Report status
COCOS 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 COCOS.
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.

COCOS is one of 71 community water systems in Puerto Rico in the 3,301 to 10,000 people size category, serving 9,930 people from groundwater.
As of August 1, 2026, its federal record holds 363 entries between 1980 and 2020, all of which EPA lists as closed. Nothing has been added since 2020.
Of the 363, 347 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 synthetic organic chemicals, volatile organic chemicals, and the Total Coliform Rules.

Common questions
Is COCOS required to publish a Consumer Confidence Report?
- Yes. COCOS 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 COCOS’s next Consumer Confidence Report due?
- COCOS’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does COCOS have any open drinking water violations on record?
- As of August 1, 2026, EPA's federal records show no open violations for COCOS.
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.
