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.

STONEGATE MD Water System

Consumer Confidence Report status

STONEGATE MD 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 STONEGATE MD.

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

System facts

System ID (PWSID): CO0118076
System type: Community Water System
Population served: 15,295
Service connections: 4,093
Ownership: local government
Water source: surface water (rivers, lakes, or reservoirs)

STONEGATE MD is one of 87 community water systems in Colorado in the 10,001 to 100,000 people size category, serving 15,295 people from surface water.

As of August 1, 2026, its federal record holds 90 entries between 1996 and 2020, all of which EPA lists as closed. Nothing has been added since 2020.

All 90 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 inorganic chemicals.
