Bioinfiltration ponds are a common way to handle stormwater runoff, by filtration through vegetation as well as infiltrating the water through soil to the groundwater table. Spokane County has asked our team to develop a design to test the influent and effluent pollutant concentrations in order to determine the effectiveness of bioinfiltration ponds removing target pollutants. In Western Washington, the Department of Ecology requires municipalities to demonstrate that stormwater best management practices (BMPs), such as bioinfiltration ponds, are functioning to acceptable levels. This will be required in Eastern Washington in the near future and Spokane County would prefer to have preliminary monitoring systems in place before it is required.
