Sources and Migration of Highway Runoff Pollutants. Volume 1. Executive Summary

摘要

The report the first in the 4 volume report summarizes the research undertaken to identify the sources of highway pollutants, and to determine their deposition and accumulation within the highway system and subsequent removal from the highway system to the surrounding environment. The purpose of the research was to identify opportunities to practice pollution mitigation. Research efforts included a literature review and field monitoring activities to determine, and quantify wherever possible: sources of highway pollutants, atmospheric deposition and removal, saltation, highway surface loads, runoff quantity and quality, groundwater percolation, accumulation of pollutants in soil and vegetation and the variables which affect the process of pollutant deposition, accumulation and removal.
