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.

HILLCREST Water System

Consumer Confidence Report status

HILLCREST 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 2 items for HILLCREST that are open and awaiting resolution. None are health-based violations — open items of this kind are most often monitoring or reporting requirements, not water-safety findings.

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 Illinois’s official records. Always confirm current status with Illinois before making decisions based on this information.

System facts

System ID (PWSID): IL1410250
System type: Community Water System
Population served: 1,224
Service connections: 445
Ownership: local government
Water source: groundwater (wells)

HILLCREST is one of 773 community water systems in Illinois in the 501 to 3,300 people size category, serving 1,224 people from groundwater.

As of August 1, 2026, its federal record holds 48 entries between 1977 and 2025, of which 2 remain open; none are health-based.

Of the 48, 42 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 Lead and Copper Rule, and volatile organic chemicals.
