2007 Annual Report
2007 Highlights LIDs are Solid Performers Porous Asphalt An Evolving Process Collaboration A Growing Resource Impact on Policy Looking Ahead
With UNHSC support, the New Hampshire Department of Transportation constructed two pilot gravel wetland treatments to help meet TMDL requirements for impaired waters as part of the Interstate 93 widening project.
2006 and 2007 were watershed years for the UNH Stormwater Center (UNHSC). We were able to complete a data set that charts the performance of stormwater treatment systems over the course of different seasons, which allows us to make more conclusive observations about the effectiveness of their performance. We also refined our process of system evaluation and expanded its scope to both look at new contaminants and to better characterize some that had already been under evaluation. At the same time, our work with the community laid the groundwork for new partnerships with municipal, state, and federal agencies, private industry, and nonprofit organizations all focused on nonpoint source pollution control and stormwater issues.
