The fate and transport of metallic pollutants through a watershed are related to the characteristics of undissolved solid particles to which they are bound. Removal of these particles and their associated pollutants via engineered structures such as settling ponds is one goal of stormwater management. Because the particles most often implicated in metal pollution have nominal diameters of
