Innovative Stormwater Treatment Technologies: Best Management Practices Manual

摘要

Urban stormwater carries a number of pathogens, nutrients, heavy metals, sediment. and other contaminants as surface runoff flows over land. The increase in impervious or paved surfaces associated with development in urban areas reduces the natural infiltration of precipitation into the ground. With impervious cover, percipitation collects and carries contaminants before draining into nearby surface waters. Stormwater runoff from paved surfaces in developed areas can degrade downstream waters with both contaminants and increased volumes of water. This publication aims to make information on innovative stormwater treatment technologies more available to New Hampshire's urban planners, developers, and communities.
