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.

NWWA OLDE COLONIAL GREENE Water System

Consumer Confidence Report status

NWWA OLDE COLONIAL GREENE 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 NWWA OLDE COLONIAL GREENE.

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

System facts

System ID (PWSID): PA1090097
System type: Community Water System
Population served: 900
Service connections: 309
Ownership: public/private mix
Water source: groundwater (wells)

NWWA OLDE COLONIAL GREENE is one of 757 community water systems in Pennsylvania in the 501 to 3,300 people size category, serving 900 people from groundwater.

As of August 1, 2026, its federal record holds 80 entries between 1985 and 2014, all of which EPA lists as closed. Nothing has been added since 2014.

Of the 80, 74 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 the Lead and Copper Rule.

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.
