POISON SPIDER I&S DISTRICT is one of 486 community water systems in Wyoming in the 500 or fewer people size category, serving 200 people from surface water.
As of August 1, 2026, its federal record holds 3 entries between 1976 and 1982, all of which EPA lists as closed. Nothing has been added since 1982.
All 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 Radionuclides and Revised Rad Rule and inorganic chemicals.
