WESTON PWS is one of 489 community water systems in Missouri in the 501 to 3,300 people size category, serving 1,850 people from groundwater.

As of August 1, 2026, its federal record holds 10 entries between 2016 and 2025, all of which EPA lists as closed.

Of the 10, 7 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 the Groundwater Rule, the Total Coliform Rules, and the Lead and Copper Rule.

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.
