AGUSTINILLO is one of 231 community water systems in Puerto Rico in the 501 to 3,300 people size category, serving 1,316 people from groundwater.

As of August 1, 2026, its federal record holds 23 entries between 2006 and 2022, all of which EPA lists as closed. Nothing has been added since 2022.

Of the 23, 22 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, inorganic chemicals, and volatile organic chemicals.

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.
