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.
Public Health - Seattle & King County's Waste Characterization Program reviews questionable waste generated in King County that is destined for disposal as municipal solid waste. The goal of the program is to keep dangerous wastes out of the solid waste stream. They determine whether a waste is dangerous or not by using information supplied by the generator, from lab analyses, MSDS's and other available information. Typical wastes reviewed include contaminated soil, sludges, expired or off-spec products and chemicals, filters, blasting/grinding wastes, empty containers, and manufacturing wastes.
The dangerous waste regulations, WAC 173-303, are the primary criteria used to designate wastes. However, the solid waste facilities clearances are issued for have policies excluding certain wastes or requiring special handling. An example of this is a dusty waste that would require special handling to minimize exposure to the workers and the public.
Waste characterization staff assist generators with profiling their waste and determining if the waste can be disposed of in the garbage. For some wastes staff will be able to provide other options such as treatment, recycling or reuse. Generators should complete the two page Waste Clearance Application and submit it to the Health Department with the appropriate data, via email, fax or the postal service. For questions on testing requirements, or further clarification, call them at 206-263-8528 or email them to firstname.lastname@example.org.
