JACABOAS Water System
Consumer Confidence Report status
JACABOAS 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 JACABOAS.
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.

JACABOAS is one of 231 community water systems in Puerto Rico in the 501 to 3,300 people size category, serving 2,678 people from groundwater.
As of August 1, 2026, its federal record holds 42 entries between 1980 and 2020, all of which EPA lists as closed. Nothing has been added since 2020.
Of the 42, 37 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, the Total Coliform Rules, and the Lead and Copper Rule.

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