Activity and Use Limitations

At this site, activity and use limitations that EPA calls institutional controls are in place. Institutional controls play an important role in site remedies because they reduce exposure to contamination by limiting land or resource use. They also guide human behavior. For instance, zoning restrictions prevent land uses – such as residential uses – that are not consistent with the level of cleanup. For more background, see Institutional Controls.

Most of the human health risk comes from polychlorinated biphenyls (PCBs), arsenic, carcinogenic polycyclic aromatic hydrocarbons (cPAHs), as well as dioxins and furans. As a result, consumption of resident fish and shellfish, as well as contact with contaminated sediments, pose a risk to human health.

Fish are nutritious and good for your health. Many people enjoy fishing on the Duwamish River. Unfortunately, the river has harmful chemicals, such as PCBs, that can cause health problems in humans. You cannot see these chemicals in the fish. They get into fish, shellfish and crab that spend their entire lives in the river (“resident fish”). The Washington State Department of Health recommends salmon as the healthiest choice to eat because they spend a short time in the river.
