BY-WILLOW MOBILE HOME PARK is one of 1,399 community water systems in Ohio in the 500 or fewer people size category, formerly serving 29 people from groundwater.

EPA's federal records list this system as inactive in 2004; the record below is historical.

As of August 1, 2026, its federal record holds 43 entries between 1985 and 2003, all of which EPA lists as closed. Nothing has been added since 2003.

Of the 43, 40 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, synthetic organic chemicals, and the Total Coliform Rules.
