Promoting Low Impact Development In Your Community, New England Environmental Finance Center Jan 2006

Promoting Low Impact Development In Your Community, New England Environmental Finance Center

Planning

Low Impact Development (LID) is an approach to stormwater management and site development that is gaining popularity throughout the country. Its attractiveness lies in its potential to lessen off-site stormwater impacts, reduce costs to municipalities and developers, and promote development that is “softer on the land” compared with typical traditional development. The approach, which is applicable to residential, commercial and industrial projects, and in urban, suburban and rural settings, often is linked with efforts by governments and citizens to foster more sustainable communities.


Cornhusker Army Ammunition Plant Nebraska, Bryant Burnett, Karla Asberry Dec 2005

Cornhusker Army Ammunition Plant Nebraska, Bryant Burnett, Karla Asberry

United States Environmental Protection Agency: Publications

The 19-square mile Cornhusker Army Ammunition Plant is a former U.S. Army Armament, Munitions, and Chemical Command facility. On standby status since 1973, the operation leases land for agriculture, grazing, and wildlife management activities. The plant was built in 1942 to produce munitions and provide support functions during World War II. It has been in and out of production over the years. The plant consists of five main components: five major production areas where munitions were loaded, assembled, and packed; a fertilizer manufacturer; two major storage facilities; a sanitary landfill; and a burning ground where materials contaminated with explosives were …


Water Quality Trading: What Can We Learn From 10 Years Of Wetland Mitigation Banking?, Eric Raffini, Morgan Robertson Jul 2005

Water Quality Trading: What Can We Learn From 10 Years Of Wetland Mitigation Banking?, Eric Raffini, Morgan Robertson

United States Environmental Protection Agency: Publications

In 2003 the U.S. Environmental Protection Agency issued its Water Quality Trading Policy. Water quality trading allows facilities facing high pollution-control costs to meet their regulatory requirements by purchasing environmentally equivalent or superior pollution reductions from another source, often at a lower cost. The policy, which hopes to achieve "water quality and environmental benefits greater than would otherwise be achieved under more traditional regulatory approaches," established the ground rules for trading and encourages states, interstate agencies, and tribes to develop and implement water quality trading programs for nutrients, sediments, and other pollutants. The policy generated controversy among some stakeholder groups; …


Hydrogeologic Model Of A Leachate Plume In An Unconfined Coastal Plain Aquifer And Chemical Transport Mechanisms Of Metals And Dense Non-Aqueous Phase Liquids, Thomas Lindblad Dec 2004

Hydrogeologic Model Of A Leachate Plume In An Unconfined Coastal Plain Aquifer And Chemical Transport Mechanisms Of Metals And Dense Non-Aqueous Phase Liquids, Thomas Lindblad

Theses and Dissertations

Groundwater contamination is of increasing environmental concern as many aquifers across the globe have experienced a decrease in water quality in recent time. The growth of the world's population over the last couple of decades has caused a dramatic increase in the rate of groundwater use. One potential source of groundwater contamination is waste material in landfills. The 1 st Division Road Sanitary landfill at Fort Benning Military Reservation was studied to evaluate the potential effect on local groundwater and a leachate plume was recognized using data from 16 groundwater monitoring wells located around the facility. The study site is …


Evaluating Uranium Depth Versus Socio-Economic Statistics For Residential Radon Vulnerability In Warren County, Kentucky, Anthony Iovanna Oct 2004

Evaluating Uranium Depth Versus Socio-Economic Statistics For Residential Radon Vulnerability In Warren County, Kentucky, Anthony Iovanna

Masters Theses & Specialist Projects

Residences in Warren County, Kentucky, are characterized by high levels of residential radon, which is one of the radioactive daughter products of uranium. According to the United States Environmental Protection Agency (US EPA), radon exposure causes approximately 22,000 lung cancer deaths in the United States per year. The City of Bowling Green, in Warren County, is underlain by karst, an easily soluble limestone subsurface, which allows radon gas to travel easily through cracks and fissures. Carbonate rocks under Bowling Green are underlain by the Devonian Chattanooga Shale, a low-grade uranium ore and a potential source of radon gas. A digital …

Atrazine Contamination In A Rural Source-Water Supply: Spa Lake, Lewisburg, Kentucky, Kathryn Seadler May 2004

Atrazine Contamination In A Rural Source-Water Supply: Spa Lake, Lewisburg, Kentucky, Kathryn Seadler

Masters Theses & Specialist Projects

In 1998, Western Kentucky University (WKU) worked in collaboration with the Environmental Protection Agency (EPA), Drinking Water Protection Division, to investigate methods to improve source-water quality for rural-water supply systems (RWSS). Through partial funding from the EPA, WKU developed a Technical Assistance Center for Water Quality (TACWQ), which focused resources and expertise toward assisting RWSS in achieving and maintaining capacity development goals and protecting public health. The TACWQ established the Source Water Protection Initiative (SWPI) to assist RWSS in acquiring and monitoring the technical, financial and managerial capacity needed to provide safe drinking water and achieve the public health protection …

Ogallala Aquifer, Robert F. Diffendal Jr. Jan 2004

Ogallala Aquifer, Robert F. Diffendal Jr.

School of Natural Resources: Faculty Publications

The Ogallala Aquifer, or High Plains Aquifer, is a porous body of complex sediments and sedimentary rock formations that conducts groundwater and yields significant quantities of water to wells and springs. The principal sediments and rocks of the aquifer range in age from 33 million years old to sediments being deposited today, but the majority is less than 12 million-years old. Much of the aquifer is composed of the Ogallala Group or Formation. The dominant sediments in the Ogallala and the other hydrogeologic units in the aquifer are riverand wind-deposited sands. The aquifer underlies about 174,000 square miles of the …

Effect Of Heavy Metals On Bacteria, Elena Vratonjic Dec 2003

Effect Of Heavy Metals On Bacteria, Elena Vratonjic

Theses and Dissertations

Heavy metals have become devastating environmental contaminants due to their widespread use in the manufacture of electronics, plastics, batteries and dyes. The discharge of heavy metals into the environment has caused concern about their effects on the ecosystem. Many metals are essential for growth in small amounts. However, at higher concentrations heavy metals are toxic because they bind to organic compounds. This accounts for their effects on some important parts of the cell structure, like their ability to denature protein molecules. The initial objective of this study was to find out the growth rate of E.coli and M.roseus in the …


Characterization Of Environmentally Friendly Polymers: Amylopectin And Its Blends, Mohammad Osman Melibari Jul 2003

Characterization Of Environmentally Friendly Polymers: Amylopectin And Its Blends, Mohammad Osman Melibari

Theses and Dissertations

Biodegradable polymers are desirable for a variety of applications, such as in packaging, agriculture, and medicine. Its biological degradation by microorganisms accelerated the interest in biodegradable polymers during the last decades. Within this group of innovative environmentally friendly biodegradable polymers, starch or Amylpectin plays a predominant role, due to their potential biodegradability. This research was attempted to characterize Amylopectin to obtain its physio-chemical properties. In addition, characterizations were extended to include blends of Amylopectin and biodegradable diluents. Blends of Amylopectin with biodegradable diluents including Polycaprolactone, Poly(DL-lactide-co-glycolide), and Poly(3- hydroxybutyric acid) were prepared. The physical properties and the thermodynamic characteristics of …
