MATANUSKA HEIGHTS DUCHESS Water System
Consumer Confidence Report status
MATANUSKA HEIGHTS DUCHESS 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 MATANUSKA HEIGHTS DUCHESS.
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 Alaska’s official records. Always confirm current status with Alaska before making decisions based on this information.

MATANUSKA HEIGHTS DUCHESS is one of 698 community water systems in Alaska in the 500 or fewer people size category, serving 36 people from groundwater.
As of August 1, 2026, its federal record holds 122 entries between 1990 and 2023, all of which EPA lists as closed. Nothing has been added since 2023.
Of the 122, 121 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.
