Pollution Sources and Potential Impacts—Next Steps
The paper presents the propositions that there is much to learn about what determines the magnitude and variability of pollutant loads in urban runoff; and with the exception of nutrient enrichment, experts cannot agree whether or not the pollution loads carried to receiving waters by urban runoff are of sufficient magnitude and duration to adversely affect the aquatic ecosystem of the receiving waters. It then goes on to summarize the findings of previous papers and the discussion that followed their presentation. Opinions of why things are where they are and what should be done about it are addressed. Subjects covered include a review of other papers presented at the meeting, runoff quality control devices, and others.
