Lower Stillaguamish River Pollution Identification and Correction (PIC) Program

The Lower Stillaguamish Pollution Identification and Correction (PIC) Program is a proactive effort to identify and correct sources of bacterial pollution specifically in the Lower Stillaguamish River Basin. The Snohomish County Public Works Surface Water Management Division is managing the program’s efforts to protect and restore water quality in the Stillaguamish River Clean Water District (CWD).

Why the Lower Stillaguamish River Basin
Pollution from the Lower Stillaguamish River Basin affects 4,950 acres of commercial shellfish growing areas as well as recreational water uses in South Skagit Bay, Port Susan, and the Stillaguamish River. This specific area has been identified as having significant bacterial pollution problems.

What is Being Done
Efforts are being focused on three pollution sources:
  • Livestock manure 
  • Failing on-site septic systems (OSS)
  • Household pet waste
Snohomish County and partners are: 
  • Raising public awareness about pollution problems and ways people can protect and restore water quality
  • Providing technical and financial assistance for agricultural best management practices and on-site septic system repairs
  • Enforcing existing water quality regulations
  • Monitoring water quality to identify and remove potential sources of bacterial pollution
