ARLINGTON COUNTY is among the 11 largest community water systems in Virginia, serving 215,000 people from surface water.
As of August 1, 2026, its federal record holds 3 entries between 1993 and 2007, all of which EPA lists as closed. Nothing has been added since 2007.
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 and the Stage 1 Disinfectants and Disinfection Byproducts Rule.
