TWMP LLC is one of 1,412 community water systems in Missouri in the 500 or fewer people size category, serving 100 people from groundwater.
As of August 1, 2026, its federal record holds 18 entries between 1992 and 2014, all of which EPA lists as closed. Nothing has been added since 2014.
Of the 18, 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 Total Coliform Rules, the Consumer Confidence Rule, and the Lead and Copper Rule.
