Arlington, Virginia maintains local programs for monitoring surface and stormwater quality and for making results available to the public. This guide explains which Arlington departments oversee testing, how the county publishes or responds to reports, and what enforcement procedures apply for violations of local water-quality related ordinances. It helps residents find official monitoring reports, request data, and take action if they suspect illegal discharges.

Arlington posts periodic monitoring summaries and maps for surface-water and stormwater on its official site.

Penalties & Enforcement

The Arlington County Department of Environmental Services (DES) enforces local ordinances and standards related to stormwater, illicit discharges, and other water-quality matters. The county relies on its code provisions and DES enforcement policies to investigate complaints, issue correction orders, and pursue penalties. Specific fine amounts and schedules are not specified on the cited county program pages; refer to the Arlington County Code and DES enforcement pages for statutory authority and current schedules.
