Microbial Source Tracking - An Overview, Sharon Long Dec 2003

Microbial Source Tracking - An Overview, Sharon Long

Water Resources Research Center Conferences

With ever increasingly specific and sensitive diagnostic methods for infectious diseases, it has become recognized that different sources of microbial inputs/contamination to drinking waters are related to different potentials for the presence of pathogenic microorganisms. Coupled with the renewed emphasis on source water protection and watershed management under the Surface Water Treatment Rule and the Long Term 2 Enhanced Surface Water Treatment Rule, many drinking water utilities may be looking towards tools that allow them to discriminate among potential microbial contamination sources in their watersheds. The use of microbial source tracking (MST) tools can also provide a utility with information …

Efficacy Of Wood Fibers For Removal Of Pollutants From Roadways, Tom Boving Dec 2003

Efficacy Of Wood Fibers For Removal Of Pollutants From Roadways, Tom Boving

Water Resources Research Center Conferences

Roadway runoff derived polynuclear aromatic hydrocarbons (PAHs) impact the quality of surface and ground water. Inexpensive aspen wood fibers have been investigated as a means to remove dissolved PAH under laboratory conditions. Our isotherm experiments demonstrated that the uptake of naphthalene, fluorene, anthracene, and pyrene required up to 12.5 days to reach equilibrium. Aspen wood-water sorption coefficients, Kww, were linearly correlated to octanol-water partition coefficients and the molecular weight of the studied PAH compounds. Column experiments were carried out to study the sorption and desorption of fluorene, anthracene, and pyrene under dynamic conditions. The results indicate linear sorption, but non-linear …

Use Of Artificial Neural Networks For Modeling Indicator Organisms In A Watershed, Diane Mas, David Ahlfeld Dec 2003

Use Of Artificial Neural Networks For Modeling Indicator Organisms In A Watershed, Diane Mas, David Ahlfeld

Water Resources Research Center Conferences

Forecasting stream water quality is important for numerous aspects of resource protection and management. Fecal coliform is one of the primary indicator organisms used to assess potential pathogen contamination in drinking water supplies. Consequently, modeling the occurrence and concentration of fecal coliform is an important tool in watershed management. While many process-based, statistical, and empirical models exist for water quality prediction, artificial neural network (ANN) models are increasingly being used for forecasting of water resources variables because ANNs are often capable of modeling complex systems for which behavioral rules are either unknown or difficult to simulate. This research presents the …

Transport Of Cryptosporidium, Giardia, Source- Specific Indicator Organisms And Standard Water Quality Constituents In Massachusetts Watersheds During Storm Events, Paula Sturdevant-Rees Dec 2003

Transport Of Cryptosporidium, Giardia, Source- Specific Indicator Organisms And Standard Water Quality Constituents In Massachusetts Watersheds During Storm Events, Paula Sturdevant-Rees

Water Resources Research Center Conferences

It is widely known that micro-organisms such as bacteria (e.g., E. coli), Giardia (often associated with beaver), and Cryptosporidium (sometimes associated with pets, livestock, and wildlife) can enter streams during rain and snowmelt events. It is also known that transport of nutrients such as phosphorus and nitrogen, in addition to total and dissolved organic carbon (TOC/DOC), may be elevated during rain and snowmelt events. It is difficult, however, to accurately determine the type and quantity of these parameters transported during such events. In addition, accurately identifying the sources of these contaminants is a difficult task. Hence, organizations responsible for public …

Source Tracking Studies In The New York City Watershed, Kerri A. Alderisio Dec 2003

Source Tracking Studies In The New York City Watershed, Kerri A. Alderisio

Water Resources Research Center Conferences

In 1990, the New York City Department of Environmental Protection (DEP) began investigating a seasonal increase in the fecal coliform concentrations in Kensico Reservoir, Valhalla, New York. This location is significant since Kensico Reservoir is the last storage reservoir prior to chlorination for approximately 80-90% of the drinking water that is delivered to nine million New York City residents daily. This study, coupled with the new coliform regulations mandated by the Surface Water Treatment Rule (SWTR), required a new approach for the way DEP microbiologists would respond to all future investigations. The DEP formed a Research Microbiology Unit that would …

Nitrogen Dynamics In A Suburban Coastal Watershed - Effects Of Population Density, Land Use, And Soil Characteristics, Michelle Daley Dec 2003

Nitrogen Dynamics In A Suburban Coastal Watershed - Effects Of Population Density, Land Use, And Soil Characteristics, Michelle Daley

Water Resources Research Center Conferences

A suburban coastal watershed in New Hampshire, the Lamprey River, will be used to develop models that link groundwater quality to landscape characteristics (land use, population density and soil characteristics) and to document biogeochemical transformations along flow paths (i.e. denitrification, adsorption of dissolved organic nitrogen (DON) and microbial uptake). Previous research in the Lamprey basin has shown that population density controls stream water nitrate export and wetlands drive DON export. These relationships will be used as the starting point for construction of groundwater models. Additionally, stream water quality will be compared to groundwater quality.

Climate Change And Water Resources In New England, S. Lawrence Dingman Dec 2003

Climate Change And Water Resources In New England, S. Lawrence Dingman

Water Resources Research Center Conferences

Hydrology is embedded in climate. The water potentially available for human use and management, Q, is determined as the difference between long-term average precipitation, P, and evapotranspiration, E: Q = P_E. 23 = 41_18 inches/yr (New England averages). P is obviously a central component of climate, and E is largely determined by climatic factors, especially temperature, humidity, wind, and the timing of precipitation inputs. The presentation will include a review of recent literature leading to an assessment of predicted and observed changes in aspects of New England hydroclimate as a result of projected global climate change. New England has experienced …

Water Quality Trends In The Connecticut River Watershed In Connecticut, John R. Mullaney, Elaine C. Todd Trench Dec 2003

Water Quality Trends In The Connecticut River Watershed In Connecticut, John R. Mullaney, Elaine C. Todd Trench

Water Resources Research Center Conferences

Degradation of water quality in the Connecticut has been documented since the late 1800’s. Throughout the late 19th century and much of the 20th century, water-quality continued to be degraded. By 1930, the wastewater discharge to the basin from towns and cities in Massachusetts and Connecticut had reached 266,000 m3/d, with only about 20 percent of the effluent having some form of minimal treatment. By 1962, 95 municipalities in four states were discharging wastewater to the Connecticut River basin; of these only 41 provided primary treatment and 26 provided secondary treatment. Industrial discharges of untreated wastes from paper, chemical, metal …

Potential Movement Of Pesticides Related To Dissolved Organic Matter From Fertilizer Application On Turf, Kun Li, Baoshan Xing

Water Resources Research Center Conferences

Turf grass systems - including golf courses, turf farms, parks and lawns - are the most intensively managed lands in the United States. Establishment and maintenance of high quality turf grass usually imply substantial inputs of water, nutrients, and pesticides. The impacts of these inputs to groundwater and surface water are a major concern of public and government agencies with over 17,816 golf courses in the U.S. and more than one new golf course opening every day (National Golf Foundation, 2002). Recent results from various facets of agricultural research have indicated very significant effects of dissolved organic matter (DOM) on …

Influence Of Land Use On Water Quality Of A Diverse Northeast Watershed - The Mill River, Amy L. Rhodes Dec 2003

Influence Of Land Use On Water Quality Of A Diverse Northeast Watershed - The Mill River, Amy L. Rhodes

Water Resources Research Center Conferences

The Mill River Watershed (MRW), a 125 km2 catchment of the Connecticut River, possesses heterogeneous human settlement patterns suitable to distinguish natural sources of chemical loading to rivers from anthropogenic sources. The MRW is divided into catchments by drainage patterns of dominant tributaries, which are further classified into land-use zones defined by intensity of human activity. Water chemistry in Zone I areas, where human activity is minimal to absent, serves as a baseline for assessing human impacts on water quality from within the watershed. Zone II areas are affected by water removal from drinking water reservoirs on two tributaries (~9500 …

Watershed-Scale Assessment Of Environmental Impacts And Hazards Of Dams, Karen Pelto Dec 2003

Watershed-Scale Assessment Of Environmental Impacts And Hazards Of Dams, Karen Pelto

Water Resources Research Center Conferences

The Department is developing a watershed-scale, GIS-based analytical framework and rating system to (1) assess the environmental impact of dams on wetland and aquatic resources, and (2) characterize the environmental hazard to wetland and aquatic resources from the uncontrolled breach or failure of dams. This system will help focus scarce public dollars on necessary environmental restoration projects through appropriate dam repair or removal. Currently, dam safety hazard ratings focus on damages to people and property. However, there is considerable potential for environmental damages if a dam failure were to release or mobilize contaminants from the sediments or from sources in …

Testing A Toolkit For Restoring The Ipswich River, Sara Cohen, Vicki Gartland Dec 2003

Testing A Toolkit For Restoring The Ipswich River, Sara Cohen, Vicki Gartland

Water Resources Research Center Conferences

In April 2003, the Ipswich River was designated as the nation’s third most threatened river by a national organization, American Rivers, due to critically low flows and extended periods of no flow. Under the direction of the Ipswich River Council, a public/private working group, a surface run-off model was adapted and used by the U.S. Geological Survey to simulate the impacts of ground water and surface water withdrawals as well as land use on the river (Zarriello and Ries, 2000). A habitat study (Armstrong et. al., 2001) in combination with the model results provided the scientific basis and quantification for …

Biogeochemistry And Natural Attenuation Of Acid- Mine Drainage At Davis Pyrite Mine, Rowe, Ma, Richard F. Yuretich, David Ahlfeld, Sarina Egas, Allan Feldman Dec 2003

Biogeochemistry And Natural Attenuation Of Acid- Mine Drainage At Davis Pyrite Mine, Rowe, Ma, Richard F. Yuretich, David Ahlfeld, Sarina Egas, Allan Feldman

Water Resources Research Center Conferences

Davis Pyrite Mine collapsed in 1910 after 28 years of operation. Since that time, acidic drainage has been transporting iron and other trace elements into a local stream and groundwater. Initial observations indicate that the environment has remained stable for decades. New data show a restricted lens of impacted groundwater that moves rapidly through the mine tailings and shallow bedrock fractures, but is contained by ambient groundwater from uncontaminated recharge areas. In these peripheral areas, there is evidence of an active microbial community that reduces the dissolved sulfate, and possibly Fe (III), to remediate the acidic drainage. Present research involves …

Land-Use Zoning And Water Quality In Jamestown, Ri: A Fractured Aquifer Case Study, Anne I. Veeger Dec 2003

Land-Use Zoning And Water Quality In Jamestown, Ri: A Fractured Aquifer Case Study, Anne I. Veeger

Water Resources Research Center Conferences

The impact of land-use and housing density on ground-water quality has been extensively studied in areas dominated by permeable surficial materials. In New England, however, many residential areas derive their water supply from fractured bedrock aquifers. The relationship between land use, in particular housing density, and water quality in these areas has received little attention and the degree to which existing zoning laws protect the fracturedbedrock ground-water resource is unclear. This study examines a detailed water quality investigation on Conanicut Island, a small fractured bedrock island in Narragansett Bay, Rhode Island. Ground-water samples were collected from 174 domestic wells in …

Raising Watershed Awareness Through Education And Recreation, David H, Small

Water Resources Research Center Conferences

For the past decade and more, government agencies and NGOs around the country have been engaged in various versions of the "watershed approach". These efforts have produced innovative collaborations and creative strategies on a number of watershed issues, and have advanced the use of sound science in environmental decision making at all levels. However, progress towards the most fundamental goal of the watershed approach is less certain: are we strengthening the relationship between the individual and the watershed? There are disturbing trends in the opposite direction - as personal schedules get busier and access to dwindling open spaces decreases, direct …

Race, Place, And Information Technology, Karen Mossberger, Caroline J. Tolbert Nov 2003

Race, Place, And Information Technology, Karen Mossberger, Caroline J. Tolbert

National Center for Digital Government

What role does environment play in influencing information technology access and skills – over and above individual characteristics such as income, education, race, and ethnicity? One of the puzzles that emerged from our recent research on the “digital divide” was that African-Americans, and to a lesser extent, Latinos, had more positive attitudes toward information technology than similarly-situated whites. And yet, African-Americans and Latinos are less likely to have information technology access and skills, even when controlling for other factors such as income and education (Mossberger, Tolbert and Stansbury 2003). The research presented in this paper takes a first step toward …

Bureaucratic Networks Or Networked Bureaucracies? Knowledge Sharing In Ict-Enabled Innovation Projects, Maria C. Binz-Scharf Oct 2003

Bureaucratic Networks Or Networked Bureaucracies? Knowledge Sharing In Ict-Enabled Innovation Projects, Maria C. Binz-Scharf

National Center for Digital Government

This paper examines knowledge sharing processes in digital government projects (DGPs). Although knowledge sharing processes are a central feature of the functioning of government, they have received little attention in the literature. The importance of knowledge sharing has become even more evident with the rise of digital government initiatives, as these have a networking effect on bureaucracies. With multiple agencies and multidisciplinary knowledge coming together, it is necessary to combine and reconnect the required knowledge. Based on empirical data from four DGPs in Switzerland and the United States, a theoretical model for knowledge sharing in DGPs is proposed. The model …
