Emerging issues

New information is continually emerging about the natural and synthetic chemicals people dispose of every day in their sinks and toilets. While scientists nationally and internationally study the effects of endocrine disrupting chemicals (EDCs), King County is taking several preventive steps to protect public health and the environment (refer to fact sheet).

Downloads and resources

Studies have shown that pharmaceuticals and chemicals in our personal care products (shampoos, lotions, perfume, bug sprays) are present in our nation's waterbodies. Research suggests that certain chemicals in drugs and personal care products may cause ecological harm.

The United States Environmental Protection Agency (EPA) and other organizations are committed to investigating this topic and developing strategies to help protect the health of both the environment and the public. To date, scientists have found no evidence of adverse human health effects from PPCPs in the environment. Learn more about:
