Is Your Fish Toxic?

Everyone deserves to know: How Toxic is Your Fish?

We’re taking fish from River to Lab to Frying Pan

Thanks to Carl Jameson from Craftmaster Productions for his great work on our video.

We’ve joined Romanian immigrants fishing in the Columbia Slough, professional guides fishing for sturgeon, and Gorge locals fishing for bass. People want to know whether their fish is safe. Our goal is to interview a diverse group of fishers and test for toxic chemicals in the very fish they are bringing home to their families. Riverkeeper is working with our friends at the River Network to analyze samples.


MEDIA COVERAGE: Riverkeeper’s results were featured in articles by The Oregonian, The ColumbianOPB’s Ecotrope blog, EcoWatchKGW Northwest News Channel 8,, and the Walla Walla Union-Bulletin. The study results reached a very broad audience across the Northwest when they were featured on-air on KGW News on 10/18. See one of the segments below:

Recent Results:

  • PCBs concentrations 27,000% above levels the EPA considers safe for unrestricted consumption
  • Mercury levels 300% above EPA safe levels
  • Detections of heavy metals such as chromium and lead
  • Endocrine disrupting toxic flame retardants

Riverkeeper launches new study, “Is Your Fish Toxic?,” featured on OPB:


What are we testing fish for?

  • Heavy metals, including mercury, arsenic, chromium and lead,
  • Cancer-causing PCBs; and
  • Toxic flame retardants that are reaching our river (called PBDEs, Polybrominated diphenyl ethers)

Why are we testing fish?

Our formula: Personal stories + laboratory analysis + smart advocacy = less pollution

The Columbia River contains too much toxic pollution. By making the direct connection to human health, we use personal stories and lab data to push for better laws, better enforcement, and cleaner water.

What are we doing to reduce toxic pollution?

Better laws

Riverkeeper helped Oregon set the most protective limits on toxic pollution in the nation. Working with tribal partners the from Umatilla and Columbia River Inter-Tribal Fish Commission, Riverkeeper’s staff attorney fought against loopholes. This victory set national precedent.

Washington, unfortunately, has one of the nation’s weakest protections for people who eat fish. Riverkeeper is pressuring the Department of Ecology to reduce toxic discharges.

Enforcing the Clean Water Act

Riverkeeper cracks down on illegal pollution by enforcing the Clean Water Act. We sue polluters. It works.

Clean water, Creative solutions

Riverkeeper works with state and federal agencies as part of the Columbia River Toxics Reduction Workgroup. As one of the only non-profits involved, we help craft creative solutions to big toxic problems. 


The Problem: Toxics in the Columbia River

The problem of toxic pollution is not theoretical: many rivers in the Columbia Basin, including sections of the mainstem Columbia River, have fish advisories that warn people not to consume certain types of fish.  The Columbia River is inundated with toxic threats:

  • Heavy metals, such as mercury from factories and coal burning;
  • Cancer-causing PCBs, DDT, and TCE that are leaching from industrial sites; and
  • Emerging pollutants, such as pharmaceuticals and endocrine disrupting chemicals from city wastewater plants.

Studies on the Columbia River show high levels of toxic contamination in certain species of fish, such as sturgeon and bass, and wildlife in some parts of the River. The U.S. Environmental Protection Agency (EPA) released a report in January 2009 which concluded that the Columbia River exceeds the safe level for PCBs, DDT, mercury, and flame retardants. Both Oregon and Washington recently added new fish advisories warning people to limit consumption of resident fish from a 150-mile reach of the mid-Columbia River.  Studies on Columbia River fish consistently demonstrate that toxic pollution is impacting one of our region’s greatest food resources. This is a major problem for people who rely on local fish as a healthy food source. Fish advisories are not the answer. People have the right to eat fish from the Columbia without the fear of getting sick. In fact, the Clean Water Act was designed to protect this right.

“We need to reduce the toxic chemicals dumped into our river everyday,” explains Brett VandenHeuvel, Executive Director of Columbia Riverkeeper. “It’s a matter of public health.”
