BROWN WATER CO is one of 1,277 community water systems in Oklahoma in the 500 or fewer people size category, formerly serving 50 people from groundwater.

EPA's federal records list this system as inactive in 2003; the record below is historical.

As of August 1, 2026, its federal record holds 3 entries between 1995 and 1997, all of which EPA lists as closed. Nothing has been added since 1997.

Of the 3, 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 Total Coliform Rules.
