Keeping poop out of water in King County

Many King County lakes, streams, and beaches have problems with poop throughout the year. The more poop in the water, the more likely there will be germs present. More germs in the water can cause more people to get sick when they play in the water or eat shellfish from polluted waters. We created a Pollution Identification and Correction (PIC) work group to find and fix sources of poop pollution.

How does poop get in the water?

Poop can get in the water from many different sources. Some of these are:

  • Broken or improperly connected side sewers
  • Improperly managed livestock manure
  • Failing on-site sewage systems
  • Persons experiencing homelessness without access to proper sanitation
  • Pet waste that is not disposed of properly
  • Poop from waterfowl
  • And more

Everyone plays a role in stopping these sources of poop, from sewer operators to dog owners. We can all do our job to protect our environment and prevent poop pollution.

How do we stop pollution and clean up poopy water?

The first step is to find where the poop is coming from. We created a Pollution Identification and Correction (PIC) work group to work together to find areas with a lot of poop pollution. There are many partners involved in this work. Our PIC work program includes scientists, planners, public health officials, managers, inspectors, and educators working together to find and fix sources of poop.

We are looking at each possible source of poop and fixing those that are causing pollution. By working together, we can see the big picture and use our resources more effectively.

If your property is connected to sewer, make sure that it isn't leaking by scoping the side sewer line. Repair any leaking side sewer lines.

If you have a dog, scoop their poop, bag it, and put it in the trash. Also, consider taking the zeropoo challenge!

Don’t share food with wildlife. When animals gather in large groups in one area, the potential for spreading diseases increase. Then it becomes a public health concern for everyone.

External partners

This PIC work would not be possible without the support of many partners. We want to thank the following external partners for their help in reducing poop pollution across King County.
