Organic Matter Sources, Composition, And Quality In Rivers And Experimental Streams, Julia E. Kelso

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Organic matter (OM) is often considered the “currency” for ecosystem processes, such as respiration and primary production. OM in aquatic ecosystems is derived from multiple sources, and is a complex mixture of thousands of different chemical constituents. Therefore, it is difficult to identify all the sources of OM that enter and exit aquatic ecosystems. As humans develop undisturbed land, the rate at which terrestrial OM (e.g. soil and plants) and associated nutrients (e.g. nitrogen) enters rivers has increased. Increased nutrients may lead to increased primary production from aquatic plants and algae, potentially causing eutrophication and harmful algal blooms. …

Four creeks within the Watauga River watershed in Northeast Tennessee are routinely monitored for water quality assessments. To identify sources and monitor remediation, Sinking Creek, Cash Hollow Creek, Buffalo Creek and Boones Creek are monitored for chemical and microbial parameters. These parameters include phosphates, nitrates, BOD and fecal coliforms. Sinking Creek is a tributary of the Watauga River with 10 miles of impaired water. Cash Hollow Creek enters the Watauga River at river mile 11.4 with 3.4 miles of impaired water. Boones Creek contains 18.6 impaired miles while the status of water quality in Buffalo Creek is not yet determined. …

Ulva Spp. Bloom Dynamics In A Hyper-Eutrophic Estuary: Jamaica Bay, New York, Annesia Lamb

Dissertations, Theses, and Capstone Projects

In this dissertation, I present three studies that further our understanding of macroalgae identity, growth, and proliferation. Eutrophication is prevalent in shallow coastal ecosystems world-wide. One of the ecosystem consequences is the development of a bloom forming green marine macroalgae, Ulva spp. Ulva can have negative effects such as Zostera spp. degradation, fish, and shellfish declines. I performed assessments of (1) identity of the bloom-forming Ulva and other macroalgae assemblage, (2) physical, chemical, and biological drivers of Ulva bloom growth and proliferation, and (3) optimal irradiance and temperature requirements for early growth stages in Ulva linza.

The first study …

Louisiana Urban And Suburban Homeowners’ Fertilizer Management Behavioral Beliefs, Intentions, And Past Behaviors, Natalie Levy

LSU Doctoral Dissertations

Nutrient runoff of nitrogen and phosphorus from improper lawn and landscape fertilization practices contributes to water quality issues within the Mississippi River drainage basin and the Northern Gulf of Mexico (NRC, 2009a; Robbins & Birkenholtz, 2003). The implementation of fertilizer best management practices has become a critical strategy for reducing nutrient runoff (Carey et al., 2012a; Carey et al., 2013; U.S. EPA, 2005). The purpose of this study was to determine if relationships exist among selected perceptual measures regarding home lawn and landscape fertilizer management practices among Louisiana urban and suburban homeowners. Ajzen’s (1991) Theory of Planned Behavior (TPB) was …

Next Generation Sequencing Methods For Coastal Zone Water Quality Monitoring, Catherine Iskrenko

HCNSO Student Capstones

When analyzing the water quality of the coastal zone, culture-based techniques have been utilized most often to identify Fecal Indicator Bacteria in samples. Since the advent of the Sanger Method for DNA sequencing, other techniques have arisen that provide significantly more information on the microorganisms in sample, but they are still not the mainstream for water quality analysis. This capstone reviews and compares culture-based techniques, DNA sequencing, RNA sequencing, qPCR for biomarker, and 16S rDNA sequencing to highlight their merits and shortcomings for analyzing environmental water samples. The technique presented that provides the broadest range of information (including the identification …

Impacts Of Sediment Dredging On Phosphorus Dynamics In A Restored Riparian Wetland, Kimberly Oldenborg

Masters Theses

Global reductions in biodiversity and water quality are having major consequences for ecosystem health and societal well-being. The restoration of riverine floodplains and wetlands provides an ideal opportunity to increase biodiversity and water quality because their hydrologic connectivity to adjacent streams and rivers promotes the formation of heterogeneous habitat while also facilitating their functioning as a nutrient sink, in general. However, many historic floodplains and riverine wetlands have been drained for the creation of agricultural land, resulting in an accumulation of nutrients in the soils. Therefore, restoration practices that hydrologically reconnect former agricultural land to an adjacent stream or river …

Clay Flocculation Effect On Microbial Community Composition In Water And Sediment, Chunyi Chen, Gang Pan, Wenqing Shi, Feng Xu, Stephen Techtmann, Susan M. Pfiffner, Terry Hazen

Michigan Tech Publications

Clay-based flocculation techniques have been developed to mitigate harmful algal blooms; however, the potential ecological impacts on the microbial community are poorly understood. In this study, chemical measurements were combined with 16S rRNA sequencing to characterize the microbial community response to different flocculation techniques, including controls, clay flocculation, clay flocculation with zeolite, and clay flocculation with O₂ added zeolite capping. Sediment bacterial biomass measured by PLFA were not significantly altered by the various flocculation techniques used. However, 16S rRNA sequencing revealed differences in water microbial community structure between treatments with and without zeolite capping. The differences were related to …

Assay Of The Reverse Osmosis Purified Water In The Life Science Building At Bowling Green State University, Ohio, Nicholas Mendenhall, Scott O. Rogers, Neocles B. Leontis

Honors Projects

Contaminated water sources can cause problems for scientific research and result in costly delays and failures of experiments. At Bowling Green State University, the reverse osmosis supply circulating in the Life Sciences Building has been measurably contaminated for nearly three years, corresponding to a change in servicing of the system. While servicing has been accelerated, the contamination in the system remains. The focus of this research was to identify the species of bacteria and fungi growing inside of the water system so that it might alert those servicing the system, and to begin to eliminate the contamination. Reverse osmosis water …

Past, Present, And Future Water Quality In Lake Union/Ship Canal, Elliott Bay, And The Duwamish Estuary And The Benefits Of Combined Sewer Overflow Control And Other Projects, Jim Simmonds

Salish Sea Ecosystem Conference

To help protect regional water quality, in 2012 King County initiated a study to review the impacts of combined sewer overflows (CSOs) and other sources of pollution to inform the region of the benefits of CSO control. King County’s Water Quality Assessment and Monitoring Study (Study) explored water quality in Lake Union/Ship Canal, Elliott Bay, and the Duwamish Estuary, where the County is planning projects to reduce the frequency of CSOs to an average of one untreated overflow per site per year over a 20-year moving average. Reducing CSO frequency to this degree is known as CSO “control” and is …

Salish Sea Ecosystem Conference

The Nooksack-Fraser transboundary area (2639 km2) is home to communities with a strong base in farming, fisheries and outdoor recreation. Water quality issues impact parts of this area, where sewage effluent and animal waste are potential sources of both fecal coliform bacteria (FCB) and nitrogen (N) in the environment. Excessive nitrogen loading can lead to eutrophication in coastal areas, and nitrate contamination of groundwater. The Nooksack-Fraser Transboundary Nitrogen (NFT-N) project was developed to determine the sources and fates of N in the watershed using data on energy use, transportation, fertilization, wastewater treatment plants, livestock operations, wildlife and more. This project …

Impact Of Septic Systems In Drayton Harbor Water Quality, Jennifer Hayden

Salish Sea Ecosystem Conference

Septic systems are personal wastewater treatment systems for rural properties. Over 3,000 septic systems exist in the Drayton Harbor watershed. Septic systems that are not maintained properly can create problems for homeowners, negatively impact water quality, and pose a public health threat. Whatcom County Health Department (WCHD) began implementing a septic system operation and maintenance (O&M) program in 2008 in the Drayton Harbor watershed when most of Drayton Harbor was classified as Prohibited for shellfish harvesting due to elevated fecal coliform bacteria levels. The local health officer’s designation of Drayton Harbor as a Marine Recovery Area in 2008 allowed WCHD …

Engaging The Community In Drayton Harbor's Comeback Story, Betsy Peabody

Salish Sea Ecosystem Conference

During the 1980 and 1990s, bacterial contamination in Drayton Harbor resulted in bay-wide closures of tribal, commercial and recreational shellfish harvest. In 2001, Puget Sound Restoration Fund partnered with local shellfish farmer extraordinaire Geoff Menzies to launch the Drayton Harbor Community Oyster Farm. With Geoff at the helm, the community farm invigorated a 20+ year community-wide effort to restore 810 acres of growing area to Approved harvest status in 2016. At the outset, seeding oysters in a bay prohibited to harvest, and involving volunteers in oyster farming, was a gamble. But the vision was that if people became immersed in …

Raising The Standards For Water Quality Objectives In Burrard Inlet: Interaction Between Public, Ecological And Cultural Values Through Indigenous-Provincial Collaboration, Anuradha Rao, Bridget Doyle, John Konovsky, Patrick Lilley

Salish Sea Ecosystem Conference

Water Quality Objectives (WQOs) in British Columbia set limits within which various parameters should remain to enable sensitive uses of water bodies. The current WQOs for Burrard Inlet are more than 25 years old and do not reflect current science, all pollutants of concern or a complete understanding of uses and values, for example uses of particular importance to First Nations. As part of its work to implement the Burrard Inlet Action Plan, Tsleil-Waututh Nation is leading an initiative with the Province of BC to update the Burrard Inlet WQOs. One goal in doing so is to ensure that ecological …

Changes To Washington State's Recreational Use Criteria And Implications For Surface Waters, Bryson Finch, Chad Brown

Salish Sea Ecosystem Conference

Washington State’s surface water quality standards set limits on pollution in lakes, rivers, and marine waters in order to protect beneficial uses, such as swimming and fishing. Washington State Department of Ecology has recently announced a rulemaking to update recreational use criteria (RUC). Recreational use criteria are intended to protect human health while enjoying water-related activities. Recreational use criteria are based on bacterial indicators rather than direct measurements of pathogens. Washington’s current bacterial indicator, fecal coliform, was removed from the Environmental Protection Agency’s (EPA) recommendations in 1986. The EPA is now requiring states update their RUC to the new bacterial …

How Did Large Scale Climate Anomalies Impact 2015 Phytoplankton Blooms In Puget Sound?, Juhi Lafuente, Christopher Krembs, S. L. Albertson, Allison Brownlee, Julia Bos, Laura Hermanson, Mya Keyzers

Salish Sea Ecosystem Conference

The Washington State Department of Ecology has been routinely monitoring marine water quality throughout the Puget Sound since 1973. An established historic baseline from 1999 to 2008 allows us to examine how water quality varies year to year as a result of both natural and human influences. The recent large scale climate anomaly, the Blob, impacted this region when a mass of warm water entered Puget Sound in fall 2014. In conjunction with higher than normal air temperatures, patterns of estuarine circulation and stratification were regionally altered in Puget Sound. Changes to these physical patterns affect ecosystem functions starting at …

Long-Term Water Quality Trend Analysis In The Lone Tree Creek Watershed And Surrounding Marine Waters, Shannon Buckham, Nicole Casper

The Lone Tree Creek watershed is located on the Reservation of the Swinomish Indian Tribal Community (SITC) and is an important area both ecologically and culturally. Lone Tree Creek and the surrounding Skagit Bay nearshore environment provide important salmon and shellfish habitats, as well as recreation areas, and therefore have been the focus for ongoing research since 1997. Water quality parameters in the creek, lagoon, and two bay sites have been monitored since the late 1990s and early 2000s, and an additional pocket estuary site was added to monitoring efforts in 2007. This study used Mann-Kendall analysis to determine how …

Social And Economic Impacts Of A 2017 Oyster-Transmitted Norovirus Outbreak In Hammersley Inlet, Puget Sound, Marisa Nixon

Salish Sea Ecosystem Conference

Hammersley Inlet in Washington State is a highly productive growing area for oysters, with at least 34 different commercial shellfish growers operating in its tidelands. The oysters in Hammersley Inlet provide an important source of income, employment and recreation for surrounding Mason County. In early spring 2017, Hammersley Inlet was implicated in a shellfish-transmitted norovirus outbreak that resulted in growing area closures and recalls, significantly impacting small, local shellfish farmers. From its initial illness investigation, Washington State Department of Health (DOH) was unable to identify a point pollution source responsible for the outbreak, and some shellfish producing parcels remained closed …

Water Quality Effects Of Fish Habitat Restoration At Lone Tree Creek, Nicole Casper, Shannon M. Buckham

Salish Sea Ecosystem Conference

Lone Tree Creek is located on the Swinomish Indian Tribal Community (SITC) Reservation. The creek’s watershed includes pocket estuary habitat, discharges over shellfish beds, an important resource for the Swinomish People, and flows into northern Skagit Bay. In 2006, extensive creek restoration replaced culverts, restored tidal influence to the pocket estuary, and planted riparian buffers, successfully restoring rearing habitat for juvenile Chinook salmon. Beyond fish habitat benefits, SITC wanted to assess long-term restoration effects on creek water quality and its associated pocket estuary, lagoon and bay. Water quality monitoring for conventional parameters and bacteria spanned 1997-2016 (10 years pre- and …

Validation Of A Water Quality Index For Lake Erie, Vaclava Hazukova

Masters Theses

This study validates a water quality index based on a diatom total phosphorus transfer function for monitoring of the Lake Erie’s pelagic zone. Lake Erie is again under the threat of cultural eutrophication, mostly due to the runoff of nutrients from the surrounding farmlands. Therefore, it is an issue of high importance to continue monitoring efforts in Lake Erie to assess further deterioration or progressive changes due to the restoration management practices. Diatom-biomonitoring represents one of the efficient and well-crafted tools to assess the actual conditions. However, indices of water quality based on diatom transfer functions are often used without …
