  • Reducing runoff pollution in the US

    Over the past century, runaway development has paved over forests, fields and wetlands across the country. Along with urbanization has come the problem of 'urban stormwater' – rainwater that washes over dirty surfaces such as roads, buildings and lawns and becomes a major source of pollution in rivers, lakes and bays. While much has been achieved in the past 30 years to limit pollution from ...

  • Reducing stormwater damage

    When an area is changing from rural to urban, city planners try to measure the impact of development on a whole host of 'quality of life' factors. What will happen to traffic patterns? Will the community need new schools? Who will provide water and sewer services, with how much capacity? These are tough questions, but they are measureable. On the other hand, the pressure of urbanization on ...

  • Fifteen Projects Unveiled to ‘Green’ Local Communities, Create Jobs and Manage Stormwater Runoff

This program was created in 2011 to encourage local jurisdictions to use “green” techniques when ...

  • Runoff research promotes healthier aquifers

    Where rain falls can influence the quality of surface water before it enters underground reservoirs, some of which provide water that eventually comes out of our taps. That's one conclusion from a collaborative study by the Agricultural Research Service (ARS) and the University of Arizona (UA). The ARS and UA scientists are investigating how urban landscapes influence storm runoff and water ...

  • Large flow stormwater separators

    View Our Extensive Line of Products One of the biggest threats to our nation's clean water supply is surface runoff from certain urban and industrial areas. Another major source of groundwater contamination comes from leaking fuel oil and gasoline tanks associated with fueling stations, tank farms and ...

  • EPA to Assist Buffalo Sewer Authority in Expanding Use of Green Infrastructure Projects to Focus on Reducing Stormwater Runoff from Vacant Lots

    The U.S. Environmental Protection Agency announced today that it will provide technical assistance to the Buffalo Sewer Authority to expand the use of green infrastructure to reduce water pollution and improve Buffalo’s resilience to the impacts of climate change. The EPA will assist Buffalo in assessing paved and unsightly vacant lots, which contribute to stormwater runoff and pollution of ...

  • Cleaning up the effects of stormwater with biofilters

    Stormwater in urban areas can have negative effects on both the quantity and quality of surface- and ground-waters. Biofiltration systems are a popular form of water treatment, but information on their performance with stormwater is limited to laboratory studies. This research is the first to evaluate three biofiltration systems in practice. Biofiltration systems (otherwise known as biofilters, ...

  • Urban water ecology

    Sewage overflows are a fact of life in urban areas, and in many cities, excess sewage water enters streams and lakes with rain runoff. Although this pollution is harmful to most organisms, there is one group of insects that thrives on it: mosquitoes. Luis Fernando Chaves, a post-doctoral researcher at Emory University, and his team discovered mosquitoes in abundance in a sewage-contaminated ...

  • EPA acts to strengthen stormwater pollution controls in guam

    The U.S. Environmental Protection Agency today announced a decision to require all dischargers of urban stormwater in Guam to obtain permits to control pollution in runoff from urbanized areas of the island. Today’s action designates all current and future municipal stormwater sources in Guam to follow Clean Water Act permitting requirements. Municipal stormwater is a leading cause of water ...

  • Dirty runoff from Massachusetts roads violates federal law

    In a precedent-setting decision, a federal court judge ruled last Friday that the Massachusetts Highway Department violated federal clean water law by failing to develop an adequate stormwater cleanup plan for its 2,500 miles of urban roads and bridges. The decision, by Judge William Young, stems from a lawsuit filed by environmentalists charging MassHighway was not properly implementing a ...

  • Landscape Architects` Green Roof Kept Runoff Out of DC Sewers
