Pollution Identification and Correction Program (PIC)

Pollution Identification and Correction Program

Many King County lakes, streams, and beaches are dirty with poop, carrying the likelihood that there will be germs present and that means that people are more likely to get sick when they play in the water or eat shellfish from polluted waters. The Pollution Identification and Correction Program finds areas with poop pollution then looks at each possible source of poop to fix those that are causing pollution in this area.
