Green Infrastructure Benefits for Communities Managing Nitrate in their Drinking Water Sources
Citation:
Yeardley, R., D. Grosse, AND J. Mccready. Green Infrastructure Benefits for Communities Managing Nitrate in their Drinking Water Sources. Presented at Ninth Annual USEPA Drinking Water Workshop, Cincinnati, OH, September 11 - 13, 2012.
Impact/Purpose:
GI techniques that provide a sustainable alternative to grey infrastructure for stormwater management and decrease algal blooms that disrupt aquatic ecosystems, also provide health and economic benefits with respect to drinking water treatment through improved water quality (e.g., less nitrates), and reduced needs for infrastructure and energy.
Description:
Nitrate in water moving through the “biologically active soil zone” of riparian zones, wetlands and streams may undergo denitrification. Therefore GI techniques such as conservation and restoration of riparian zones, wetlands and streams (daylighting) have the potential to remove excess nitrate that can be a health and economic issue for communities.
