Bioretention Media Component Analysis to Improve Runoff Treatment

Herrera. 2017. Bioretention Media Component Analysis to Improve Runoff Treatment. Prepared for Kitsap County, by Herrera Environmental Consultants, Inc., Seattle, Washington.
The goal of this study is to develop recommendations for a statewide, high-performance bioretention soil media (BSM) specification that: 1) reduces contaminant flushing; 2) meets Ecology treatment objectives for total suspended solids, dissolved copper and zinc, and phosphorus; 3) grows plants; 4) is affordable and available; and 5) minimizes toxicity to aquatic organisms. This study tests individual media components for potential contaminant export and sorption capability, and media blends for hydraulic conductivity and plant fecundity.
