"Stormwater frequently contains contaminants that pollute ground and surface waters. As water becomes an increasingly scarce commodity, groundwater recharge and preventing water pollution has been identified as a key aspect of sustainability. Recent research shows bioretention basins as an effective management practice to reduce pollutants of concern in stormwater including total suspended solids, oil and grease, heavy metals, pathogenic bacteria, and some forms of nutrients. This study evaluates three different plant species for use in bioretention basins. Two native wetland species, Carex comosa and Iris virginica and one non native plant species, Poa pratensis were tested to evaluate stormwater treatment in bioretention basins."--From abstract.
