ARMSTRONG is one of 1,412 community water systems in Missouri in the 500 or fewer people size category, formerly serving 265 people from surface water.

EPA's federal records list this system as inactive in 2014; the record below is historical.

As of August 1, 2026, its federal record holds 26 entries between 1993 and 2011, all of which EPA lists as closed. Nothing has been added since 2011.

Of the 26, 6 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 Surface Water Treatment Rules, the Stage 1 Disinfectants and Disinfection Byproducts Rule, and the Total Coliform Rules.
