Consumer Confidence Report status
ALTOONA WATER AUTHORITY 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 ALTOONA WATER AUTHORITY.
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.

ALTOONA WATER AUTHORITY is one of 175 community water systems in Pennsylvania in the 10,001 to 100,000 people size category, serving 62,500 people from surface water.
As of August 1, 2026, its federal record holds 248 entries between 1982 and 2026, all of which EPA lists as closed.
Of the 248, 197 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 Surface Water Treatment Rules, and volatile organic chemicals.

When is ALTOONA WATER AUTHORITY’s next Consumer Confidence Report due?
- ALTOONA WATER AUTHORITY’s next Consumer Confidence Report is due by July 1, 2027. The report covers calendar year 2026.
Does ALTOONA WATER AUTHORITY have any open drinking water violations on record?

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.
