ELMO PWS is one of 1,412 community water systems in Missouri in the 500 or fewer people size category, serving 169 people from surface water.
As of August 1, 2026, its federal record holds 5 entries between 2003 and 2025, of which 1 remains open; none are health-based.
Of the 5, 3 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 Total Coliform Rules, and the Lead and Copper Rule.
