Water pollution aspects of street surface contaminants.

MATERIALS WHICH COMMONLY RESIDE ON STREET SURFACES HAVE BEEN FOUND TO CONTRIBUTE SUBSTANTIALLY TO URBAN POLLUTION WHEN WASHED INTO RECEIVING WATERS BY STORM RUNOFF. CALCULATIONS BASED ON A HYPOTHETICAL BUT TYPICAL U. S. CITY INDICATED THAT THE RUNOFF FROM THE FIRST HOUR OF A MODERATE-TO-HEAVY STORM WOULD CONTRIBUTE CONSIDERABLY MORE POLLUTIONAL LOAD THAN WOULD THE SAME CITY'S SANITARY SEWAGE DURING THE SAME PERIOD OF TIME. THE STUDY PROVIDES A BASIS FOR EVALUATING THE SIGNIFICANCE OF THIS SOURCE OF WATER POLLUTION AND PROVIDES INFORMATION FOR COMMUNITIES HAVING A BROAD RANGE OF SIZES, GEOGRAPHICAL LOCALES, AND PUBLIC WORKS PRACTICES. INFORMATION WAS DEVELOPED FOR MAJOR LAND-USE AREAS WITHIN THE CITIES. THE ANALYSIS OF THE RUNOFF IS ALSO REPORTED. /AUTHOR/
