Sewer System Infrastructure And Stressors On Water Quality In Streams Within The Alplaus Watershed In Upstate Ny, Camryn Ragland Jun 2022

Sewer System Infrastructure And Stressors On Water Quality In Streams Within The Alplaus Watershed In Upstate Ny, Camryn Ragland

Honors Theses

Healthy aquatic ecosystems require clean water, but many creeks and streams may be impaired by human activity. This study is focused on surface water quality of the Alplaus, and Indian Kill streams located within the Alplaus Watershed in Schenectady and Saratoga Counties (NY). The primary goal of this study is to understand the extent of water quality impairment within the Alplaus and Indian Kill using a range of indicators to understand the impacts of failing infrastructure and stressors to surface water. Sixty-five water samples were collected in the fall of 2021 from six locations in the Alplaus and Indian Kill …


Groundwater Isotopes Across Scales: Continent-Wide Modeling And Local Field Characterization, Jaclyn Gehring Jun 2020

Groundwater Isotopes Across Scales: Continent-Wide Modeling And Local Field Characterization, Jaclyn Gehring

Honors Theses

Groundwater is one of the world’s most important natural resources. The use of stable water isotopes (𝛿2H and 𝛿18O) as natural tracers through the water cycle has provided a unique observational technique for characterizing hydrological processes and establishing connections between water distribution systems and their respective environmental sources. Groundwater contains information about the timing and efficiency of recharge, allowing for the use of isotopes to understand the physical hydrology and climatic influences on such processes in places with groundwater isotope measurements. We estimate the seasonal recharge proportion and efficiency at thousands of locations across the U.S., …


Remote Water Metering In Venecia, Nicaragua, Jeffrey Wettstein Jun 2015

Remote Water Metering In Venecia, Nicaragua, Jeffrey Wettstein

Honors Theses

The senior Capstone Design Project is the culmination of over three years of undergraduate work in electrical engineering, and other related fields. The project allows students to demonstrate their knowledge on a tangible design. Starting from a blank slate, the Capstone process asks students to carefully move through every stage of design in order to create the most effect output. Water shortage is a major problem for the entire world including the United States, but particularly in developing countries like Nicaragua. The community of Venecia, Nicaragua has a unique water problem. Community members leave taps running in fear that if …


Documenting The Anthropogenic Impact On Ballston Lake New York From A Short Core Using Stable Isotopes Of Carbon And Nitrogen And Trace Metals, Taylor S. Labrecque Jun 2012

Documenting The Anthropogenic Impact On Ballston Lake New York From A Short Core Using Stable Isotopes Of Carbon And Nitrogen And Trace Metals, Taylor S. Labrecque

Honors Theses

Ballston Lake occupies a portion of an avulsed channel of the Mohawk River between Schenectady and Saratoga Springs, New York. The lake is about 5 km long, generally less than 200m wide, ~8-15m deep, dimictic, with a catchment basin area of ~22km2. Long cores (>8 m) indicate that the lake formed ~13,000 cal yr BP. This study was undertaken to document recent environmental change recorded in the upper portion of sediment in Ballston Lake. Three sediment cores ~40 cm long were acquired from ~8 m water depth at the north end of Ballston Lake (42°57.101’N, 73°51.066’W), and were analyzed …


The Gilboa Dam And Its Possible Failure : What It Means For Nyc And Upstate New York, Kelly C. Owings Jun 2008

The Gilboa Dam And Its Possible Failure : What It Means For Nyc And Upstate New York, Kelly C. Owings

Honors Theses

The majority of the NYC water supply is provided by a system of dams and reservoirs that have been created in upstate New York. As the owner of this water supply system, NYC is responsible for managing each of the dams and reservoirs within the system. This responsibility includes upholding dam regulations in order to ensure the safety of the citizens of the surrounding area and to lesson any environmental impacts that may occur due to the water supply system. Of the 30 dams owned by NYC, however, 25 of them have been identified at a high-hazard level according the …
