United States Environmental Protection Agency: Staff Publications
We constructed a seasonal nitrogen (N) budget for the year 2008 in the Calapooia River Watershed (CRW), an agriculturally dominated tributary of the Willamette River (Oregon, U.S.) under Mediterranean climate. Synthetic fertilizer application to agricultural land (dominated by grass seed crops) was the source of 90% of total N input to the CRW. Over 70% of the stream N export occurred during the wet winter, the primary time of fertilization and precipitation, and the lowest export occurred in the dry summer. Averaging across all 58 tributary subwatersheds, 19% of annual N inputs were exported by streams, and 41% by crop …

Long-Term Variation Of Summer Phytoplankton Communities In An Urban Lake In Relation To Lake Management And Climate Conditions, Yuan Xiao Grund
Dissertations and Theses
Eutrophication is one of the primary factors causing harmful cyanobacteria blooms in freshwater lakes; climate change such as warmer temperature can potentially further increase both frequency and intensity of blooms. This study investigated the long-term changes in water quality and summer phytoplankton assemblages in Oswego Lake, OR, in relation to lake management practices (e.g., hypolimnetic aeration and alum treatments), as well as climatic and regional meteorological conditions. Both water quality and phytoplankton assemblages were sampled biweekly during summer seasons between 2001 and 2013. The concentrations of total phosphorus (TP), soluble reactive phosphorus (SRP) and total nitrogen (TN) decreased 66%, 93% …

Ulva Spp. Bloom Dynamics In A Hyper-Eutrophic Estuary: Jamaica Bay, New York, Annesia Lamb
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 …
Next Generation Sequencing Methods For Coastal Zone Water Quality Monitoring, Catherine Iskrenko
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 …
Using Wetlands To Prevent The Surface Accumulation Of Aphanizomenon Flos-Aquae From Upper Klamath Lake, Arick Christopher Rouhe
Using Wetlands To Prevent The Surface Accumulation Of Aphanizomenon Flos-Aquae From Upper Klamath Lake, Arick Christopher Rouhe
Dissertations and Theses
The ability to regulate buoyancy (sinking and floating) using cellular gas vesicles is a unique characteristic that allows many common bloom-forming cyanobacteria to accumulate at water surfaces and dominate systems. Typical control and management strategies include nutrient manipulation and phosphorus reduction, which are effective but do not reduce the advantage of buoyancy control. Since buoyancy control is based upon a mechanism that is driven by photosynthesis along with environmental conditions that trigger vesicle formation and ion exchange, buoyancy regulation can be influenced by manipulating extracellular conditions. In this study I manipulated extracellular conditions using wetland water and additions of potassium, …

Short-Term Organic Carbon Release And Chlorine Disinfectant Decay For Cross-Linked Polyethylene (Pex) Plumbing Pipes, Miriam Tariq, Christian J. Ley, Maryam Salehi, Andrew J. Whelton
The Summer Undergraduate Research Fellowship (SURF) Symposium
The use of cross-linked polyethylene (PEX) plumbing pipes has grown in popularity for residential applications. However, PEX pipes can leach organic materials into water that can enable biofilm growth, cause off-tastes and -odors, and may react with disinfectants to form disinfection by-products (DBP). Varied manufacturing processes that are applied to create PEX pipes add to the complexity of understanding organic materials released. In this study, organic carbon release from three PEX pipe brands was monitored for up to five days using a series of stagnation periods. Seven stagnation periods of 1, 2, 4, 8, 24, 72, and 120 hours were …

Nutrient Transport And Storage In A Karst Spring-Reservoir System During Baseflow, Missouri Ozarks, Heather A. Moule
MSU Graduate Theses
Urban and agricultural land uses are important sources of nitrogen and phosphorus which, if in excess, can cause eutrophication in lakes and rivers. There have been few studies of nutrient transport and storage in karst spring and reservoir connected stream systems draining the Missouri Ozarks. This study aims to link the baseflow nutrient contributions of Sanders Spring to downstream reservoir outflow and the Headwaters South Dry Sac River Watershed in Springfield, Missouri. Water samples were collected seasonally and analyzed for total nitrogen (TN), total phosphorus (TP), and several other water quality parameters. Discharge was also monitored to calculate water and …
A 30 Year Assessment Of Fecal Indicator Bacteria (Escherichia Coli And Enterococci) Along The Shoreline Of Santa Monica Bay, California, Chris Enyart
LMU/LLS Theses and Dissertations
Santa Monica Bay and its vast beaches are important Los Angeles icons, while also providing significant ecosystem services to over millions of recreational visitors annually. Contaminated runoff from numerous watersheds surrounding the Bay, especially the 87% urbanized Ballona Creek Watershed, have historically resulted in poor water quality along areas of the Bay shoreline. Decades of monitoring for fecal indicator bacteria (FIB) along the Bay’s shoreline has been associated with NPDES wastewater discharge and stormwater programs. Many projects have been implemented throughout the watersheds (e.g. sewer improvements, biofiltration systems, low-flow diversions (LFDs)) to lessen flows of runoff from contaminating surf zone …

Environmental Assessment Of Road Brining And Injection Wells For Disposal Of Oil And Gas Liquid Waste, Marissa Madia
Electronic Theses and Dissertations
The dramatic increase in oil and gas drilling operations in Pennsylvania over the last decade has presented a challenge for their wastewater disposal (e.g., flowback, produced water). Currently, these fluids are treated in permitted brine treatment plants or exported out of state to deep injection well facilities. In Pennsylvania, road brining for dust control is permitted for conventional well brines, and permits for three injection wells for unconventional brines are pending. This study focused on water quality impacts due to road brining in Farmington Township (45 samples) and ground and surface water in Grant Township (41 samples) prior to the …
Water Quality Assessment In The Santa Fe River: Tracking Pollution Sources Via Quantitative Polymerase Chain Reaction Analysis, Hayley Aurora Hajic
Water Quality Assessment In The Santa Fe River: Tracking Pollution Sources Via Quantitative Polymerase Chain Reaction Analysis, Hayley Aurora Hajic
Geography ETDs
Microbial contamination affects many water bodies in the United States and pathogens associated with contamination pose a threat to human health. While the nation’s lakes, streams and rivers have been monitored for decades, many still do not meet the requirements of the 1972 Clean Water Act. Due to the number of pathogens that occur in water bodies, it is not feasible to directly monitor all of them. Instead of testing for a plethora of pathogens, it is standard practice for water divisions to monitor fecal indicator bacteria (FIB) as a proxy to determine water quality. There are significant flaws, however, …
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 …

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 …

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 …

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
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 …

Technical Reports
Nonpoint source pollution associated with human land use (agriculture and urbanization) is one of the leading causes of impairment to waterways in the United States (EPA, 2000). The primary pollutants associated with agricultural and urban land use are sediment and nutrients which enter nearby streams during rain events and are then carried downstream. These sediments and nutrients may result in water quality issues in the downstream water bodies like increased algal growth or decreased water clarity (e.g. Smith et al., 1999).

Water Quality Performance And Greenhouse Gas Flux Dynamics From Compost-Amended Bioretention Systems & Potential Trade-Offs Between Phytoremediation And Water Quality Stemming From Compost Amendments, Paliza Shrestha
Graduate College Dissertations and Theses
Stormwater runoff from existing impervious surfaces needs to be managed to protect downstream waterbodies from hydrologic and water quality impacts associated with development. As urban expansion continues at a rapid pace, increasing impervious cover, and climate change yields more frequent extreme precipitation events, increasing the need for improved stormwater management. Although green infrastructure such as bioretention has been implemented in urban areas for stormwater quality improvements and volume reductions, these systems are seldom monitored to validate their performance. Herein, we evaluate flow attenuation, stormwater quality performance, and nutrient cycling from eight roadside bioretention cells in their third and fourth years …
