Clean Streams

Clean Fairfax and Fairfax County are working together to keep our streams clean!




Clean Fairfax is partnering with the Department of Public Works and Environmental Services, the Soil and Water Conservation District, and community groups to fulfill a piece of the MS4 (Municipal Separate Storm Sewer System) five-year permit. This permit pertains to untreated water that is runoff from storms into streams, not from wastewater pipes or treatment plants.  For more information about the MS4 permit in Fairfax County, go to


Identify sources of stream litter, and work to eliminate litter from our streams.


Phase 1: Identification of Streams

  • Accessibility
  • Availability of cleanup volunteers at least twice a year
  • “Trashiness”
  • Pollution source

Phase 2: Action

  • Monitor four times a year (counting visible trash—“floatables”)
  • Clean two times a year

Phase 3: Outreach and Education

  • Identify litter source(s)
  • Develop and implement plan to stop the litter flow

January 2017 Update:

We are currently finalizing our selection of monitoring sites ensuring that we have a variety of land uses and levels of trashiness to make the monitoring reflect streams in Fairfax County.
