Includes bibliographical references. "In the Province of Ontario, in spite of recent improvements in point source controls through programs like MISA, in most urbanized areas it is impossible to attain Water Quality targets and restore beneficial uses without some control of stormwater and combined sewer overflow discharges. Highways and associated land corridors may produce significant volumes of runoff conveying a variety of contaminants and since traditionally, the design of highway drainage focused on removing runoff to ameliorate traffic safety issues, the impact of dispersed highway runoff was rarely considered. To develop some appreciation of such impacts a preliminary study of the toxicity of highway runoff was conducted. For this preliminary survey-type study of toxicant and genotoxicant presence in highway runoff, a section of the QEW highway (Burlington Skyway) was selected. Two runoff samples were collected, one within minutes of the onset of a heavy storm and another after approximately 15 hours of light rainfall. These samples were tested with a battery of bioassays to establish the presence of toxicants"--Abstract. gccst Pollutants gccst Water management Dutka, B. J. Canada. Environment Canada.
