OSBORN PWS is one of 1,412 community water systems in Missouri in the 500 or fewer people size category, serving 405 people from groundwater.
As of August 1, 2026, its federal record holds 6 entries between 1996 and 2013, all of which EPA lists as closed. Nothing has been added since 2013.
Of the 6, 4 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 inorganic chemicals, the Consumer Confidence Rule, and the Lead and Copper Rule.
