BLENCOE MUNICIPAL WATERWORKS is one of 1,221 community water systems in Iowa in the 500 or fewer people size category, serving 224 people from groundwater.
As of August 1, 2026, its federal record holds 10 entries between 1987 and 1995, all of which EPA lists as closed. Nothing has been added since 1995.
All 10 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, volatile organic chemicals, and the Lead and Copper Rule.
