Assessment of Pollutant Loadings and Concentrations in Highway Stormwater

Description: This report presents the final form of the Washington State highway runoff pollutant loading model, incorporating data from the five years of study. It also features a probabilistic analysis of concentration and loading data designed to express the chance of exceeding specific values in a given case. Other topics include further assessment of the toxicity of highway runoff and its causes and mitigation.
