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.

System facts

System ID (PWSID): PR0613366
System type: Community Water System
Population served: 1,015
Service connections: 380
Ownership: privately owned
Water source: groundwater (wells)

ACUED. COM. SECTOR LA SIERRA is one of 231 community water systems in Puerto Rico in the 501 to 3,300 people size category, serving 1,015 people from groundwater.

As of August 1, 2026, its federal record holds 82 entries between 1992 and 2024, of which 1 health-based item remains open, alongside 1 other open entry.

Of the 82, 23 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 Total Coliform Rules, the Lead and Copper Rule, and the Public Notice Rule and Revised PN Rule.
