Is DEAN TWP WATER SYSTEM required to publish a Consumer Confidence Report?

Yes. DEAN TWP WATER SYSTEM is a community water system, and federal rules (40 CFR 141 Subpart O) require every community water system to publish a Consumer Confidence Report each year.

When is DEAN TWP WATER SYSTEM’s next Consumer Confidence Report due?

DEAN TWP WATER SYSTEM’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.

Consumer Confidence Report status

DEAN TWP WATER SYSTEM 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 DEAN TWP WATER SYSTEM.

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

System facts

System ID (PWSID): PA4110042
System type: Community Water System
Population served: 216
Service connections: 76
Ownership: local government
Water source: groundwater (wells)

DEAN TWP WATER SYSTEM is one of 3,064 community water systems in Pennsylvania in the 500 or fewer people size category, serving 216 people from groundwater.

As of August 1, 2026, its federal record holds 162 entries between 1984 and 2026, all of which EPA lists as closed.

Of the 162, 153 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 volatile organic chemicals, synthetic organic chemicals, and inorganic chemicals.

Common questions

Is DEAN TWP WATER SYSTEM required to publish a Consumer Confidence Report?: Yes. DEAN TWP WATER SYSTEM is a community water system, and federal rules (40 CFR 141 Subpart O) require every community water system to publish a Consumer Confidence Report each year.
When is DEAN TWP WATER SYSTEM’s next Consumer Confidence Report due?: DEAN TWP WATER SYSTEM’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does DEAN TWP WATER SYSTEM have any open drinking water violations on record?: As of August 1, 2026, EPA's federal records show no open violations for DEAN TWP WATER SYSTEM.
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.
