Coronavirus (COVID-19) office closure
We're following the Gov. Inslee's directive to stay home and stay healthy. Accordingly, we are joining a statewide effort to slow the spread of coronavirus by having staff work from home. Due to the coronavirus (COVID-19) outbreak, we are adjusting our normal business processes as appropriate. While continuing our work, we will do everything possible to keep people safe, provide support to our regulated entities, and to accommodate public participation.
The Nuclear Waste Program office in Richland is closed. Staff are available by email, but will not be available for walk-in service until further notice.
Please send all official correspondence and other documents to the Nuclear Waste Program resource center, email NWPmail@ecy.wa.gov.
You can also leave a message or reach a receptionist during normal business hours at 509-372-7950 (stay on the line for a live person).
We work to ensure that the U.S. Dept. of Energy — Hanford's owner and manager — follows environmental laws. We work with the U.S. Environmental Protection Agency to make sure that Energy's cleanup deadlines are met, as outlined in the Tri-Party Agreement that governs Hanford site cleanup.
What you need to know about Hanford
The nuclear weapons production that began at Hanford in the 1940s generated substantial amounts of radioactive and chemical wastes, contaminated land and groundwater, and created a lasting legacy of contaminated facilities. Since the signing of the Tri-Party Agreement in 1989, Ecology, EPA, and Energy have worked to clean up, treat, and dispose of this legacy to reduce the threats it poses. Substantial progress has been made, and substantial work remains.
During World War II, the government wanted a large buffer zone around its nuclear production facilities for secrecy and public safety. The current site is about 580 square miles and most areas are still not accessible to the public.
- In the 1980s, groundwater contamination totaled about 80 square miles. Today, about 60 square miles of groundwater remains contaminated above federal standards — and the level of contamination has been greatly reduced for significant portions of that area.
- There are no active nuclear production facilities; however, the site contains some of the nation's most complicated nuclear and mixed dangerous waste, which must be cleaned up.
The U.S. Department of Energy is required to maintain security and prevent unauthorized access to contaminated areas of the site. In the event of an emergency, Energy is required to effectively respond to protect human health and the environment.
We work to keep the Columbia River safe
State and federal governments monitor the Hanford site and the Hanford Reach of the Columbia River for contaminants, and inform the public of possible risks. Results are published in
annual groundwater reports.
Although the Columbia River basin covers parts of many states and tribal lands, the Columbia River meets all surface
water quality standards. Water taken from the river by cities downstream is used for drinking water, and the cities that use Columbia River water comply with the federal
Safe Drinking Water Act.
