GC14C:
Urbanization and Water Quality I

Submit an Abstract to this Session



Session ID#: 32547

Session Description:
By 2050, 70% of the world's population will live in cities (UN-Habitat). As the urban population grows, increases in impervious surfaces, combined-flow sewers and non-point source contaminants put water resources at risk. These include changes in discharge of potential carcinogens, elevated nutrients, and weathering products from roads and buildings. Urban surface waters present unique challenges to mitigation efforts. Both rivers and urban lakes are likely to suffer similar non-point source contamination. Faced with these challenges, municipalities have increasingly become interested in reclaiming waterways by introducing "green" technologies/adaptations aimed at improving water quality. Identifying the sources, effects, and solutions to the complex issues facing urban surface waters requires a cadre of scientists, managers, and community activists to conceive and implement solutions. In this session, we welcome submissions focusing on both the changing water quality and biogeochemistry of urban surface waters, as well as efforts to reduce adverse impacts on these systems.
