Toxic stormwater runoff is threatening salmon populations in Seattle. An article published by Washington State University, Hope for saving salmon lies in reducing stormwater pollution, details the current threats to the salmon population and offers solutions with research. The salmon exposed to toxic stormwater can die within a matter of hours from time of exposure. Salmon are essential to the Pacific human experience as their presence tells us that our rivers are still healthy and provide food for humans and animals such as grizzly bears. Additionally, salmon fuel a $3 billion industry, supporting tens of thousands of jobs and local economies around the Pacific Rim.
We’ve seen it in California and other urban areas around the U.S. where improper stormwater treatments have led to decreased clean water supplies that affect the human and animal population. As Washington State University researchers suggest the implementation of systems that pretreat and filter stormwater decreases the risk of contaminating water supplies.
“Washington State University researchers suggest that bioretention systems, such as rain gardens, that filter out contaminants from stormwater runoff are key for preventing lethal impacts on fish.”
Who would’ve thought that stormwater could be the potential demise of a $3 billion industry and the livelihood of one of nature’s most beloved species of fish? We mentioned the use of rain gardens in our previous blog here where we were able to circle back and say, “hey, what about our drywells?” The MaxWell® drywell and drainage systems are proven to be effective stormwater pretreatment systems that have been installed across the southwest for over 43 years. Imagine the combination of rain gardens and drywells in these mainly urban areas where toxic stormwater runoff is affecting more than just groundwater.
