Illegal dumping: How to issue a complaint

Illegal dumping is the dumping solid waste onto the surface of the ground or into the waters of the state, except at a permitted disposal site. It's known in the regulations as "unlawful" dumping. Solid waste includes garbage, rubbish, abandoned vehicles or parts, demolition and construction waste, recyclable materials, etc.

Unlawful dumping is enforced by Public Health - Seattle & King County through the code of the King County Board of Health Title 10, Chapter 10.11.

Why illegal dumping a public health problem

  • Decomposing garbage and other solid waste can provide food and habitat for rats, other rodents and other disease vectors. A vector is an insect or animal that has the potential to carry disease.

  • Hazardous materials illegally dumped can cause direct effects on people's health, and can get into the water supply and create downstream health effects on people and the environment.

  • Illegal dumping creates eyesores on our streets, reducing our quality of life, property values, and a feeling of safety and well-being in our communities.
