Leaks pollute the ground, water and indoor air

Half of the 600 contaminated sites in Pierce County are from leaky USTs. We work with property owners and consultants to clean up current and historic contaminated underground storage tank (UST) sites. We issue cleanup and tank-removal permits and provide guidance to get started.

USTs store fuel and other liquids. Leaks can happen at gas stations, industrial sites, schools and hospitals. These sites are harmful to our health, the environment and our economy.
