Trend Analysis Of Water Quality In Northwest Arkansas Streams Reflects Changes In The Watershed, Zachary Paul Simpson

Graduate Theses and Dissertations

Watershed export of nutrients, sediments, and chemicals impacts receiving waters. Changes within the watershed (e.g., anthropogenic or climatic) can alter the transport of constituents in streams. Stream monitoring is crucial for understanding these effects. This study developed a potential improvement to flow-adjusting constituent concentrations in streams, an important step of analyzing monitoring data in lotic systems for trends. The method incorporates a K-fold cross-validation procedure to optimize a model explaining the relationship between the concentration and streamflow, thus providing a valuable tool to researchers in water quality. Additionally, two case studies were conducted on watersheds located in northwest Arkansas using …

Electrodeionization Versus Electrodialysis: A Clean-Up Of Produced Water In Hydraulic Fracturing, Brigitte Marie Rodgers

Graduate Theses and Dissertations

Electrodeionization (EDI) is a widely studied process ranging from applications in wastewater clean-up in the food and beverage industry to purifying organic compounds. To date, there are no apparent studies on applying this technology to produced wastewater recovered from hydraulic fracking sites. Water consumption within hydraulic fracturing sites can reach in the upwards of millions of gallons per site, so a need for a water recycling process becomes necessary within areas where water requirements are scarce. Implementation of an EDI module that is capable of handling high salt solutions from produced wastewater in subsequent fracturing practices will decrease overall water …

Flood Events Can Reduce Key Fatty Acid Content Of Early-Stage Benthic Algal Assemblages In An Urban Stream, Sarah Whorley, John Wehr

Articles & Book Chapters

Effects of urbanization on stream chemistry and biota have been widely examined. However, few studies quantify the effect of urban stream characteristics on the biochemical properties of basal food resources, such as benthic algae, which can affect aquatic consumers and food webs. A common feature of urban streams is the high frequency of short floods, which may disrupt aquatic communities and their biotic controls. These disturbances can create algal assemblages low in biomass and which remain in early successional stages. This study examined the effects of frequent flood events and macroinvertebrate grazing on biomass, elemental stoichiometry, and essential fatty acid …

The Selective Survival Of Escherichia Coli In Freshwater Beach Sand, Natalie Ann Rumball

Theses and Dissertations

The quantification of Escherichia coli or E. coli is the most common method used to detect recent fecal pollution in recreational water, as this species is known for its high abundance in fecal matter and assumed host-associated nature. However, it has been determined that some strains are capable of long-term survival and potential propagation in non-host environments, such as the beach sand. These long-term environmental survivors are host-independent and are not associated with the same health risks as those E. coli from recent fecal pollution. However, they have been shown to impact how water quality is perceived as they are …

Characterization Of Dom And Its Interactions With Invasive Quagga Mussels In Lake Michigan, Stephen Devilbiss

Theses and Dissertations

Green Bay is the largest freshwater estuary in the Laurentian Great Lakes and receives disproportional terrestrial inputs. While seasonal hypoxia and the formation of “dead zones” in Green Bay have received increasing attention, there are no systematic studies on the dynamics of dissolved organic matter (DOM) and its linkage to the development of hypoxia. During summer 2014, bulk dissolved organic carbon (DOC) analysis, UV-vis spectroscopy, and fluorescence excitation-emission matrices (EEMs) coupled with PARAFAC analysis were used to quantify the abundance, composition and source of DOM and their spatiotemporal variations in Green Bay, Lake Michigan. Concentrations of DOC ranged from 202 …

Cockatoo Sands In The Victoria Highway And Carlton Hill Areas, East Kimberley: Hydrogeology, Aquifer Properties And Groundwater Chemistry, D L. Bennett, John Andrew Simons, Richard J. George Dr, Paul Raper

Resource management technical reports

Cockatoo Sands are recognised as potentially suitable for irrigated agriculture because they are generally well drained and not subject to waterlogging or inundation. These characteristics allow them to be cultivated and prepared for planting various crops during the wet and dry seasons of northern Australia. Expanding agricultural production onto the Cockatoo Sands around Kununurra will increase opportunities for agriculture by increasing the overall scale of agriculture, allowing year-round agricultural enterprise, new crops and new market opportunities.

DAFWA has assessed the soil characteristics and agriculturally suitable areas of Cockatoo Sands in the Victoria Highway and Carlton Hill areas near Kununurra. Potential …

Dietary Effects On The Stoichiometry Of Growth, Regulation, And Wastes Of Ozark Stream Insect Detritivores, Halvor Matthew Halvorson

Graduate Theses and Dissertations

A widespread stressor, anthropogenic nitrogen (N) and phosphorus (P) pollution can increase resource nutrient content and alter animal community composition in freshwater ecosystems. In this dissertation, I used ecological stoichiometry theory to examine effects of diet nutrient content and leaf litter type on growth, regulation, and wastes of aquatic invertebrate detritivores. I tested effects of leaf litter diet carbon:phosphorus (C:P) on growth and stoichiometric regulation of the detritivorous caddisfly Pycnopsyche lepida and used results to determine a threshold elemental ratio of oak litter C:P=1620 that confers peak growth of this species. This empirical, growth-based approach provided a more accurate estimate …

The Role Of Hydrologic Regimes In Driving Morphologic Divergence And The Trait Compositions Of Fish Assemblages, Lindsey A. Bruckerhoff

Graduate Theses and Dissertations

The hydrologic regime is an important determinant of the ecological integrity of a stream. Hydrologic regimes are defined by the magnitude, timing, frequency, rate of change, and duration of high and low flow events and capture long term patterns of variability and predictability of water movement in a stream. Flow regimes influence many aspects of the biophysical environment in lotic systems; therefore organisms have adapted to natural flow patterns. We investigated how fish have adapted to flow regimes at both a population and community level. In the first study presented in this thesis, we hypothesized fish exhibit phenotypic divergence to …

A Method Comparison And Stressor-Response Experimental Study Of Nitrogen And Phosphorus Impacts To Periphyton In Ozark Streams, Ashley Renee Rodman

Graduate Theses and Dissertations

Stream bioassessment is important for understanding algal-nutrient relationships and the development of scientifically defensible numeric nutrient criteria. However, multiple methods of periphyton data collection are currently used, and little is known about the comparability of resulting datasets. Literature also suggests other factors besides nutrients (i.e. variable grazing, light, and flow) can confound algal-nutrient relationships. A one-year method comparison study and 31-day algal biomass-nutrient manipulative experiment were conducted in the southern Ozarks of Arkansas. The method comparison study was implemented using two common bioassessment procedures (whole-surface and delimiter-reduced periphyton removal) to assess the potential for combining datasets. During the manipulative experiment, …

Effects Of Streamflows On Stream-Channel Morphology In The Eastern Niobrara National Scenic River, Nebraska, 1988–2010, Nathaniel J. Schaepe, Jason S. Alexander, Kiernan Folz-Donahue

United States Geological Survey: Water Reports and Publications

The Niobrara River is an important and valuable economic and ecological resource in northern Nebraska that supports ecotourism, recreational boating, wildlife, fisheries, agriculture, and hydroelectric power. Because of its uniquely rich resources, a 122-kilometer reach of the Niobrara River was designated as a National Scenic River in 1991, which has been jointly managed by the United States Fish and Wildlife Service and National Park Service (NPS). To assess how the remarkable qualities of the National Scenic River may change if consumptive uses of water are increased above current levels, the United States Geological Survey (USGS), in cooperation with the NPS, …

Dissolved Oxygen Monitoring In Kings River And Leatherwood Creek, Eric Cummings, Erin E. Scott, Marty Matlock, Brian E. Haggard

Technical Reports

The Clean Water Act (CWA) establishes the basic structure used to regulate water quality. Under the CWA, States are required to assess water bodies relative to water‐quality standards and designated beneficial uses and then to submit lists of impaired bodies every other year to the US Environmental Protection Agency (USEPA). In 2015, at least 4,800 water bodies were listed as impaired by dissolved oxygen across the US (USEPA, 2015). Aquatic species like fish and macroinvertebrates depend on adequate dissolved oxygen for survival. Low dissolved oxygen can lead to fish kills, reduced aquatic diversity, and nuisance smells from anaerobic conditions – …

Water Balance Monitoring For Two Bioretention Gardens In Omaha, Nebraska, 2011–14, Kellan R. Strauch, David L. Rus, Kent E. Holm

United States Geological Survey: Water Reports and Publications

Document abstract

Bioretention gardens are used to help mitigate stormwater runoff in urban settings in an attempt to restore the hydrologic response of the developed land to a natural predevelopment response in which more water is infiltrated rather than routed directly to urban drainage networks. To better understand the performance of bioretention gardens in facilitating infiltration of stormwater in eastern Nebraska, the United States Geological Survey (USGS), in cooperation with the Douglas County Environmental Services and the Nebraska Environmental Trust, assessed the water balance of two bioretention gardens located in Omaha, Nebraska by monitoring the amount of stormwater entering and …

Sediment Loads And Transport At Constructed Chutes Along The Missouri River-Upper Hamburg Chute Near Nebraska City, Nebraska, And Kansas Chute Near Peru, Nebraska, Brenda K. Densmore, David L. Rus, Matthew T. Moser, Brent M. Hall, Michael J. Andersen

United States Geological Survey: Water Reports and Publications

The United States Geological Survey (USGS), in cooperation with the United States Army Corps of Engineers, monitored suspended sediment within constructed Missouri River chutes during March through October 2012. Chutes were constructed at selected river bends by the US Army Corps of Engineers to help mitigate aquatic habitat lost through the creation and maintenance of the navigation channel on the Missouri River. The restoration and development of chutes is one method for creating shallow-water habitat within the Missouri River to meet requirements established by the amended 2000 Biological Opinion. Understanding geomorphic channel-evolution processes and sediment transport is important for the …

Agriculture Causes Nitrate Fertilization Of Remote Alpine Lakes, Elizabeth J. Hundey, Sam S.D. Russell, Fred Longstaffe, Katrina A. Moser

Earth Sciences Publications

Humans have altered Earth’s nitrogen cycle so dramatically that reactive nitrogen (Nr) has doubled. This has increased Nr in aquatic ecosystems, which can lead to reduced water quality and ecosystem health. Apportioning sources of Nr to specific ecosystems, however, continues to be challenging, despite this knowledge being critical for mitigation and protection of water resources. Here we use D¹⁷O, d¹⁸O and d¹⁵N from Uinta Mountain (Utah, USA) snow, inflow and lake nitrate in combination with a Bayesian-based stable isotope mixing model, to show that at least 70% of nitrates in aquatic systems are anthropogenic …

Climate-Relevant Land Use And Land Cover Change Policies, Rezaul Mahmood, Roger A. Pielke Sr., Clive Mcalpine

HPRCC Personnel Publications

Both observational and modeling studies clearly demonstrate that land-use and land-cover change (LULCC) play an important biogeophysical and biogeochemical role in the climate system from the landscape to regional and even continental scales. Without comprehensively considering these impacts, an adequate response to the threats posed by human intervention into the climate system will not be adequate. Public policy plays an important role in shaping local- to national-scale land-use practices. An array of national policies has been developed to influence the nature and spatial extent of LULCC. Observational evidence suggests that these policies, in addition to international trade treaties and protocols, …

Constituent Loads And Trends In The Upper Illinois River Watershed And Upper White River Basin, Erin E. Scott, Zach P. Simpson, Brian E. Haggard

Technical Reports

Water chemistry can greatly influence the quality of surface waters and affect the ability for streams and rivers to meet their designated use(s). In Arkansas, many streams and rivers were placed on the 2008 303(d) list of impaired water bodies due to excess levels of nutrients, chlorides, sulfates, and sediments (ADEQ, 2008). These constituents continue to be listed as the potential cause for water‐quality impairments through the most recent draft 303(d) list (ADEQ, 2014). The Arkansas Non‐Point Source (NPS) Management Program wants to reduce poll‐ utant loading from the landscape and improve water quality, where funding for projects is targeted …

Kitsap County partnered with San Juan County and the Washington Department of Fish and Wildlife to objectively review and assess the effectiveness of existing marine shoreline stabilization permitting programs in achieving a balance between applicant needs and protection of nearshore resources. Utilizing a T.A.C.T. approach (Troubleshooting, Action planning, Course correction and Tracking & monitoring), the agencies worked together to identify gaps and overlap in the permit review and monitoring process, as well as the effectiveness of permit provisions (conditions) through field assessment of recent marine shoreline armoring projects. Actions to correct these internal deficiencies and …

Cross-Border Citizen Action: Protecting The Salish Sea From The Risks Of Fossil Fuel Transport, Alexandra L. Woodsworth

Salish Sea Ecosystem Conference

Currently, more than a dozen oil, coal and liquid natural gas projects are proposed on both sides of the border, threatening the health of the Salish Sea and its communities, as well as the global climate. Recent estimates suggest that if all the projects were to be approved, each year they would generate an extra 308 million tonnes of carbon dioxide emissions and an additional 1,200 ship journeys through the already-busy waters of the Salish Sea. Each fossil fuel project proposed in BC and Washington is currently being assessed in isolation from the others by the government agencies that are …

Simulating The Dispersal Of Invasive Clams In A Freshwater Lake Using A Three-Dimensional Hydrodynamic Model; A Prototype For Simulating Invasions In Marine Ecosystems, Elizabeth Kilanowski, Lambert Rubash

Salish Sea Ecosystem Conference

The discovery of several populations of an invasive Asian clam (corbicula fluminea) in Lake Whatcom, the drinking water source for approximately 100,000 people in Northern Washington State, created a need among elected officials, local government staff, and the public for a better understanding of lake hydrodynamics during the reproductive season for the Asian clam, and for times when Quagga and Zebra mussel invasions are likely. Seasonal vertical thermal stratification of the lake and a desire to predict likely locations of additional clam populations or of new populations of mussels led to the choice of a model that could be configured …

Protecting Puget Sound From Csos By Retrofitting Urban Neighborhoods With Green Stormwater Infrastructure, Kathryn Gwilym Pe, John Phillips, Steve Burke Pe, Peg Staeheli Fasla

Salish Sea Ecosystem Conference

In 2009 King County Wastewater Treatment Division (KCWTD) selected green stormwater infrastructure (GSI) as the preferred alternative for controlling combined sewer overflows (CSO) for the 1100-acre Barton combined sewer system (CSS) basin in Seattle. In 2008 KCWTD reported that the basin had an average of four overflows per year that discharge a total of four million gallons into Puget Sound. In order to reduce the overflows to no more than one CSO event per year for Washington State’s Department of Ecology compliance, KCWTD retrofitted 15 residential streets with bioretention cells in order to intercept, treat and reduce the amount of …

A Nonparametric Statistical Approach To Analyzing Eelgrass Density Data, Traci L. Sanderson, Michelle Spani, Andrew Rippington

Salish Sea Ecosystem Conference

As part of continuing work in Port Gamble, WA a diver-based eelgrass survey was completed to support the application for a Hydraulic Project Approval (HPA), as required by the Washington State Department of Fish and Wildlife (WDFW) for in-water work. The survey was completed following interim guidelines established by WDFW in 2008, although to fit the guidelines to the specific project some methods were modified and approved by WDFW. Collecting statistically robust data proved to be difficult, as shoot density in the eelgrass bed was highly variable. In some areas the variance was so high that power calculations estimated the …
