BLACK OAK WATER & SEWER CO is one of 1,412 community water systems in Missouri in the 500 or fewer people size category, serving 477 people from groundwater.
As of August 1, 2026, its federal record holds 4 entries between 1985 and 1999, all of which EPA lists as closed. Nothing has been added since 1999.
Of the 4, 2 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 Consumer Confidence Rule, the Lead and Copper Rule, and the Total Coliform Rules.
