The students of Qualters Middle School performed a study called “Benthic Macroinvertebrate Exploration in the Rumford River”. The study was conducted on October 16, 2007 in Mansfield, Massachusetts. The study location consisted of one site located at 143 Chauncy Street.

The purpose of this study was to introduce benthic macroinvertebrates and their role as indicators for evaluating stream water quality. Students utilized state of the art methods and techniques during all aspects of this study.

The Rumford River is listed on the Environmental Protection Agencies (EPA) National Priority List (NPL). The river was polluted with dioxins, furans and phenols by …


Comparative Nutrient Data For Two Locations On The Marstons Mills River Dec 2007

Comparative Nutrient Data For Two Locations On The Marstons Mills River

Watershed Access Lab Projects

On October 30, 2007, we deployed water samplers at two locations along the Marstons Mills River: River Road and Hyrdo Dam/Route 28. We programmed a Sigma at each location to take a water sample each hour for 24 hours, to determine the amount of dissolved nutrients in the water in the course of one day. When compared to the discharge at each site, we found that the Hydro Dam location moved nearly 117 000 000 liters of water, 10 000 grams of phosphorus, and 25 000 grams of nitrogen-nitrate each day. Only a short distance upstream, the River Road location …

An Environmental Assessment Of Little Black Lake, Alan D. Steinman, Mary Ogdahl, Carl Ruetz Nov 2007

An Environmental Assessment Of Little Black Lake, Alan D. Steinman, Mary Ogdahl, Carl Ruetz

Scientific Technical Reports

A limnological survey was conducted of Little Black Lake and its tributaries during summer 2007 by researchers at the Annis Water Resources Institute of Grand Valley State University. Water quality, sediment composition, and phytoplankton, macrophyte, and fish abundance and composition were analyzed. In general, the water quality of both the inflows to, and Little Black Lake itself, was good. Nutrient concentrations occasionally exceeded existing guidelines, but no systemic problems were detected. Phosphorus concentrations did increase during stormflow conditions, but this is typical and concentrations were not considered excessive. One site in the lake had very high sediment phosphorus concentrations. Because …

Fecal Microbe Distribution And Abundance Used As A Possible Proxy For Nutrient Source Identification In Eutrophic Wilgreen Lake, Madison County, Kentucky, Theresa A. Aguiar, Walter S. Borowski Nov 2007

Fecal Microbe Distribution And Abundance Used As A Possible Proxy For Nutrient Source Identification In Eutrophic Wilgreen Lake, Madison County, Kentucky, Theresa A. Aguiar, Walter S. Borowski

EKU Faculty and Staff Scholarship

Wilgreen Lake is a eutrophic lake that has been listed on the EPA’s 303d list as nutrient impaired. Potential sources of this impairment are from humans, cattle manure and fertilizers. We suspect that the majority of nutrients originate from human sources. As a possible proxy for nutrient input, we test our hypothesis by examining fecal microbe distribution and abundance in the lake.

We took water samples at 19 sampling locations on 4 occasions. Sampling spanned 26 June to 15 August with the last 3 sampling events occurring at roughly two-week intervals. These samples were then processed using IDEXX methods, which …

Coastal Maritime Forests In Virginia – Delineation And Distribution, Marcia Berman, Harry Berquist

Reports

This project had two major goals. The first builds on an earlier effort by the Virginia Department of Forestry, who delineated maritime forests using remote sensing techniques. Their project integrated land use and soils data to generate a map that defines potential boundaries of maritime forest. This study follows an identical approach with two major exceptions. The first is the soils data used in this study is mapped at a much finer scale. The second is this study has a field validation component that reviewed random sites around selected locations to ground-truth the remote sensing output. The Virginia Department of …

An Update On Groundwater Conditions At The Site Of The York College Cuny Campus In Southeastern Queens County, New York City, Nazrul I. Khandaker, Stanley Schleifer, Zarine Ali, Edward A. Molteni

Publications and Research

The wells operated by the Jamaica Water Supply Company in Queens represent the only large scale utilization of groundwater for public water supply in New York City in recent years. These wells were shut down, for the most part, beginning in 1996. Since that time, water table elevations in the area, which had been drawn down by the withdrawal activity of the Jamaica Water Supply Company, have risen significantly causing some high groundwater problems, including flooding of basements. The New York City Department of Environmental Protection (NYCDEP) has held public hearings on a contemplated resumption of ground water withdrawal in …

Land Cover Types Of The Las Vegas Wash, Nevada, Seth A. Shanahan, Dave Silverman, Art Ehrenberg Sep 2007

Land Cover Types Of The Las Vegas Wash, Nevada, Seth A. Shanahan, Dave Silverman, Art Ehrenberg

Publications (WR)

Vegetation type, extent, continuity, and structure are some of the most important factors that determine wildlife diversity and distribution. Other contributing factors that shape wildlife communities include disturbance, competition, climate, and water availability. Because vegetation communities in the southwestern U.S. gradate sharply along zones of soil moisture, wildlife are often restricted to specific vegetation types. Along the Las Vegas Wash (Wash), Nevada, more than 250 wildlife species have been documented to occur in distinct wetland, riparian, and upland vegetation types. Recent studies have investigated the diversity and distribution of amphibians, birds, fishes, mammals, and reptiles (Shanahan 2005, 2005a, Van Dooremolen …

Environmental Controls On The Landscape-Scale Biogeography Of Stream Bacterial Communities, Noah Fierer, Jennifer L. Morse, Sean T. Berthrong, Emily S. Bernhardt, Robert B. Jackson

Environmental Science and Management Faculty Publications and Presentations

We determined the biogeographical distributions of stream bacteria and the biogeochemical factors that best explained heterogeneity for 23 locations within the Hubbard Brook watershed, a 3000-ha forested watershed in New Hampshire, USA. Our goal was to assess the factor, or set of factors, responsible for generating the biogeographical patterns exhibited by microorganisms at the landscape scale. We used DNA fingerprinting to characterize bacteria inhabiting fine benthic organic matter (FBOM) because of their important influence on stream nutrient dynamics. Across the watershed, streams of similar pH had similar FBOM bacterial communities. Streamwater pH was the single variable most strongly correlated with …


Organic Geochemical Investigation Of A Highly Contaminated Urban Waterway: The Gowanus Canal, Brooklyn, New York, Usa, Michael A. Kruge, Kevin K. Olsen, Eric A. Stern Sep 2007

Organic Geochemical Investigation Of A Highly Contaminated Urban Waterway: The Gowanus Canal, Brooklyn, New York, Usa, Michael A. Kruge, Kevin K. Olsen, Eric A. Stern

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

The Gowanus Canal is an industrial waterway constructed in the mid-19th century by widening and deepening a natural tidal channel. It is ca. 3 km in length and empties into Gowanus Bay, an arm of New York Harbor. Its banks, reinforced by bulkheads and piers, became the site of intensive industrial activity, including oil refining, coal gasification, soap making and tanning. Even though much of the industrial activity along the canal has ceased, its sediments remain highly enriched in organic and inorganic contaminants, with combined sewer outfalls continuing to transport pollutants into the canal. The canal area remains densely …


Estimating Business And Residential Water Supply Interruption Losses From Catastrophic Events, Nicholas Brozovic, David L. Sunding, David Zilberman Aug 2007

Estimating Business And Residential Water Supply Interruption Losses From Catastrophic Events, Nicholas Brozovic, David L. Sunding, David Zilberman

Daugherty Water for Food Global Institute: Faculty Publications

Following man-made or natural catastrophes, widespread and long-lasting disruption of lifelines can lead to economic impacts for both business and residential lifeline users. As a result, the total economic losses caused by infrastructure damage may be much higher than the value of damage to infrastructure itself. In this paper, we consider the estimation of economic impacts on businesses and residential consumers resulting from water supply disruption. The methodology we present for estimating business interruption losses assumes that marginal losses are increasing in the severity of disruption and that there may be a critical water availability cutoff below which business activity …

Shallow Water Fish Communities And Coastal Development Stressors In The Lynnhaven River, Donna M. Bilkovic, David Stanhope, Kory Angstadt

Reports

Coastal development pressures in the Mid-Atlantic have been attributed to significant negative impacts to aquatic ecosystems. The Lynnhaven River watershed, located in the southernmost extent of the Chesapeake Bay and encompassing Virginia Beach, is an example of a shallow-water tidal system under intense development pressure that is confronted with multiple and often conflicting coastal management issues. Rapid development in and around the City of Virginia Beach over the past few decades has led to the loss of natural buffers and habitat (e.g. oyster, wetlands and seagrasses), increased sedimentation, and degraded water quality. The Lynnhaven Ecosystem Restoration Project, led by U.S …
