Stormwater Action Monitoring — source identification
SAM's source control studies are focused on learning which actions by permittees and businesses in Western Washington are key to preventing illicit discharges. We are also gaining a better understanding of how to detect sources of pollution to stormwater.
What are we learning?
Stormwater Action Monitoring (SAM) completed one source identification study during the 2013-2018 permit cycle and three more projects are under contract development. SAM source identification projects results can be used across jurisdictions.
