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.

Data sourced from the EPA ECHO database (SDWA bulk download), last refreshed August 1, 2026.

System facts

System ID (PWSID): PA2640056
System type: Community Water System
Population served: 44
Service connections: 17
Ownership: privately owned
Water source: groundwater (wells)

MOUNTAIN CREST DEVELOPMENT is one of 3,064 community water systems in Pennsylvania in the 500 or fewer people size category, serving 44 people from groundwater.

As of August 1, 2026, its federal record holds 133 entries between 2002 and 2026, all of which EPA lists as closed.

Of the 133, 130 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.

When is MOUNTAIN CREST DEVELOPMENT’s next Consumer Confidence Report due?: MOUNTAIN CREST DEVELOPMENT’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.

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.
