UNHSC announces the release of its 2012 biennial reportFriday, October 19, 2012
We are happy to announce the release of our 2012 biennial report! This is the last general report on our research summarizing 8 years of stormwater BMP research funded by CICEET. We thank you all for your patience and support over the years and sincerely hope that this information will be useful.
EPA's Webinar on Stormwater, Coal-Tar Sealcoat, and Polycyclic Aromatic Hydrocarbons (PAHs)Monday, June 04, 2012
EPA's Webinar on Stormwater, Coal-Tar Sealcoat, and Polycyclic Aromatic Hydrocarbons (PAHs)
June 14, 2012 01:00pm - 03:45pm Eastern ---EPA’s Stormwater Pollution Prevention Webinar Series will highlight efforts to reduce pollutants in stormwater through controlling these pollutants at their sources. The first in EPA’s Stormwater Pollution Prevention Webinar Series will cover the topic of Stormwater, Coal-Tar Sealcoat, and Polycyclic Aromatic Hydrocarbons (PAHs). The webinar will present information on the prevalence of PAHs from coal-tar-based sealcoat in the environment, and on the environmental and human health impacts. The webinar will also cover actions taken to address PAHs by a state and a city.

Portsmouth's State Street Receives Outstanding Civil Engineering Achievement Award for 2010Sunday, October 30, 2011
Portsmouth's State Street Project Receives ASCE NH Award – The transformation of Portsmouth's State Street has received recognition as the Outstanding Civil Engineering Achievement Award for 2010 by the New Hampshire Section of the American Society of Civil Engineers. The project was led by CMA Engineers of Portsmouth, NH, partnering with the UNHSC for the LID design. The State Street Redesign included a combined sewer separation, the use of a numerous tree filters, a large subsurface chamber system in series with an underground sand filter and other forms of advanced stormwater management.
Berry Brook Restoration Project-Urban Watershed RenewalThursday, August 25, 2011
Water quality and stream restoration improvements will be targeted in the Berry Brook Watershed from 2011-2013. Berry Brook, a tributary to the Cocheco River, is a 0.9 mile long stream in a 164 acre watershed in downtown Dover. The brook is impaired for aquatic habitat and primary contact recreation. Through a series of three grants and matching funding from the City of Dover, this project will implement some of the major recommendations from the 2008 Watershed Management Plan for Berry Brook.
NH Stormwater Commission Report SummarySaturday, May 14, 2011
This document summarizes the major points from the Stormwater Study Commission November 2010 Final Report. The New Hampshire legislature established the Stormwater Commission in 2008 to identify issues and find solutions to reduce impacts from stormwater runoff. This Summary Brief is a non-technical overview intended for the legislature and other public officials. The report includes 5 major recommendations for action.
Stormwater is recognized as one of the leading causes of water pollution in the United States. In New Hampshire, stormwater contributes to over 80% of the surface water quality impairments according to water quality data compiled by NH DES. Impervious surfaces (e.g., roads, rooftops, parking lots, lawns in the shoreland zone) and other land use development cause most stormwater runoff. Moreover, increasing imperviousness from development contributes to increased frequency and magnitude of flooding. Recent flooding in NH, exacerbated by imperviousness, has resulted in a tragic loss of life and millions of dollars of damage to our road and highway systems, private residences, and business properties. New regulations and action is needed on a State level in preference to and advance of new Federal regulations
WA Set to Ban Coal-Tar SealcoatMonday, March 28, 2011
Washington State is poised to become the first state to ban coal-tar sealant used on pavements and parking lots.
A state measure—overwhelmingly approved last month by the House and now under consideration in the WA Senate—would ban the toxic asphalt sealant derived from coal tar, a waste product of steelmaking.
Polycyclic aromatic hydrocarbons, more commonly known as PAHs, occur in oil, coal, and tar-based products, and are also produced as byproducts of fuel burning. The EPA considers these products to be carcinogenic and heavily regulate activities known to be sources of PAHs such as coking operations and coal gasification processes.
For decades, home and business owners have been seal coating their driveways and parking lots. Research conducted by the USGS, the UNHSC and others indicates that sealcoat activities, especially with coal tar based sealant products, may contribute significant amounts of polycyclic aromatic hydrocarbons entering waterways from stormwater runoff.
