Evaluation Of A Sequential Pond System For Detention And Treatment Of Runoff At Skypark, Santa's Village, Elizabeth Caporuscio
Evaluation Of A Sequential Pond System For Detention And Treatment Of Runoff At Skypark, Santa's Village, Elizabeth Caporuscio
Electronic Theses, Projects, and Dissertations
Understanding the extent to which human activities impact surface water resources has become increasingly important as both human population growth and related landscape changes impact water quality and quantity across varying geographical scales. Skypark, Santa’s Village is a 233.76-acre tourism-based outdoor recreation area located in Skyforest, California residing within the San Bernardino National Forest. The park is situated at Hooks Creek, the headwaters of the Mojave River Watershed, and is characterized by a diverse landscape that includes forest cover and human development, including impervious surfaces, a restored meadow, and recreational trails. In 2016, Hencks Meadow was considered degraded by human …
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 …
Nutrient Transport And Storage In A Karst Spring-Reservoir System During Baseflow, Missouri Ozarks, Heather A. Moule
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 …
How To Sample: Collecting Water Samples Is So Easy, Anyone Can Do It!, Mike Daniels, Bradley J. Austin, Brian E. Haggard
How To Sample: Collecting Water Samples Is So Easy, Anyone Can Do It!, Mike Daniels, Bradley J. Austin, Brian E. Haggard
Fact Sheets
The Arkansas Water Resources Center (AWRC) runs a water quality lab that anyone can use to have their water sample tested. The AWRC Lab is certified for the analysis of water samples, but the quality (and meaningfulness) of the data generated by the Lab is also dependent on you – the client. This fact sheet provides you some general guidance on how to properly collect your water sample.
Exploratory Assessment Of Risks From Drinking And Recreational Water Exposure To Children In The State Of New Jersey, Brandon M. Owen, Neha Sunger
Exploratory Assessment Of Risks From Drinking And Recreational Water Exposure To Children In The State Of New Jersey, Brandon M. Owen, Neha Sunger
Public Health Sciences Faculty Publications
In this study, we conducted a worst-case risk assessment for children’s health from ingestion exposure to water sources in two densely populated counties of the Piedmont province of New Jersey—Hunterdon and Mercer counties. Carcinogenic and non-carcinogenic health risk estimates for 19 contaminants, representing 3 different chemical classes—organic, inorganic and contaminants of emerging concern (CEC), for which environmental monitoring data are available—were generated. The three exposure scenarios examined were: (1) ingestion exposure to untreated groundwater from contaminated private wells; (2) recreational exposure through incidental ingestion of water from the Delaware River; and (3) ingestion exposure through fish consumption sourced from the …

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).

Watershed Management Tools: Hazardous Site Case History, Reference Stream Analysis, And Gis Analysis Of Fire Risk, Patrick Doyle
Graduate Student Portfolios, Professional Papers, and Capstone Projects
My portfolio explores some tools that are used to protect or assess watershed health and the experiences and lessons I learned during my time in the Environmental Studies program. The first piece in my portfolio is a case study that looks at the history of pollution ad cleanup of the kraft pulp mill along the Clark Fork River. In my study, I look closely at the EPA’s investigation of the site and the community’s reaction to the findings. In my second piece, I describe my field and lab experience working for the Montana Department of Environmental Quality. During this time, …
Annual Report 2018, Casco Bay Estuary Partnership
Annual Report 2018, Casco Bay Estuary Partnership
Publications
CBEP has been collaborating for over 25 years with a multitude of partners working hard to protect Casco Bay. 2018 brought us new and exciting collaborations.
The Casco Bay Nutrient Council, convened by CBEP, met for almost two years and produced a report that laid a path forward for all partners to tackle nutrient pollution.
CBEP worked closely with the EPA to establish the Casco Bay Monitoring Network, made up of over 20 member organizations, aimed at coordinating and upgrading monitoring in the Bay. The Network is currently updating the Casco Bay Monitoring Plan.
CBEP is an active participant in …

The availability of freshwater supplies to meet future demand is a growing concern. Water availability metrics are needed to inform future water development decisions. Furthermore, with the help of water managers, water availability was mapped for over 1300 watersheds throughout the 31-contiguous states in the eastern U.S. complimenting a prior study of the west. The compiled set of water availability data is unique in that it considers multiple sources of water (fresh surface and groundwater, wastewater and brackish groundwater); accommodates institutional controls placed on water use; is accompanied by cost estimates to access, treat and convey each unique source of …
Smallholder Farmers, Environmental Change And Adaptation In A Human-Dominated Landscape In The Northern Highlands Of Rwanda, Apollinaire William
Smallholder Farmers, Environmental Change And Adaptation In A Human-Dominated Landscape In The Northern Highlands Of Rwanda, Apollinaire William
Antioch University Full-Text Dissertations & Theses
Climate change and crop intensification are key challenges to the livelihoods and wellbeing of the majority of rural smallholder farmers in developing countries, particularly in human-dominated, climate-sensitive landscapes such as the northern highlands of Rwanda where issues of fluvial floods, soil erosion pose serious threats to the livelihoods of smallholder farmers. In this mixed methods study conducted between August and December 2015, I explored smallholder farmers’ perceptions by examining what barriers might hinder the process of agroforestry adoption by smallholder farmers, what socio-economic and physical factors and attitudes influence crop choices, motivations for smallholder farmers’ willingness to plant trees within …
