Impact Of Prairie Restoration On Geochemistry And Microbial Communities In Groundwater, Kayla Koenig

Graduate Research Theses & Dissertations

Prairie restoration is important for reversing the loss of biodiversity and repairing ecosystem functions humanity is dependent on diverse ecosystems. This study looks at the impact of the beginning phases of prairie restoration on groundwater geochemistry and microbial communities the relationship between them. This research project studied the geochemistry and microbial communities in five wells before, during, and after the beginning phases of the first year of a prairie restoration on the Northern Illinois University campus. Water samples were collected bimonthly for a year and analyzed on an Ion Chromatograph. Microbial samples were collected monthly and underwent DNA extraction, amplification, …

Use Patterns And Influencing Factors Of Irrigation Best Management Practices In The Lower Mississippi River Basin, Merri E. Day

Graduate Theses and Dissertations

This study uses the 2016 Irrigation Survey from Arkansas, Louisiana, and Mississippi to document the use of irrigation best management practices (IBMPs), analyze use patterns, and use quantitative methods to determine factors that influence producers’ decisions regarding IBMPs. IBMPs included in the survey can be grouped as: field management practices (zero-grade leveling, precision-grade leveling, end blocking, warped surface, and deep tillage), water flow control practices (computerized pipe-hole selection, multiple-inlet irrigation, surge irrigation, alternate wetting and drying, cutback irrigation, flow meters, and pump timers), water recovery/storage practices (tail-water recovery system and on-farm storage reservoir), and advanced irrigation scheduling practices (soil moisture …

Spatiotemporal Observations Of Water Stress In Kansas Winter Wheat And Corn From Remotely Sensed Evapotranspiration And Ndwi, Lindi Diane Oyler

Masters Theses

"Optimizing water use is a growing concern, especially in agricultural communities where water use is high. An important challenge in agricultural water optimization is knowing when and where crop water stress is occurring, particularly on large scales where in-situ measurements are no longer practical to obtain. In an effort to combat this challenge, this study utilizes remotely sensed evapotranspiration (ET) and Normalized Difference Water Index (NDWI) to evaluate the responses of integrated satellite datasets to water-stressed conditions over fields of irrigated corn, irrigated winter wheat, and rainfed winter wheat from 2007 to 2017 in southwestern Kansas. Using two different ET …

Impact Of Excessive Pumping On Groundwater Quality: The Arsenic Problem Of The Ganges–Meghna–Brahmaputra Delta In Southeast Asia, Rhitwik Chatterjee, Mousumi Chowdhury

Journal of Environmental Science and Sustainable Development

This review of the impact of large-scale pumping on arsenic distribution reveals that groundwater-fed irrigation and domestic withdrawal impart tremendous stress on the limited groundwater resource base and disrupts the dynamic equilibrium of the groundwater system of the Ganges–Meghna–Brahmaputra (GMB) delta in Southeast Asia. Excessive groundwater extraction through pumping affects the groundwater quality in three major ways. First, excessive pumping transports atmospheric oxygen and organic-rich surface water to the subsurface. Second, it promotes arsenic build up in surface soil irrigated with arsenic-laced groundwater. Finally, it shifts groundwater replenishment zones lying at various depths near extraction points, thus, carrying dissolved arsenic …

Disadvantaged Vs. Non-Disadvantaged Drinking Water: San Joaquin County Groundwater Variable By Contaminant, Megan Brooks

Master's Projects and Capstones

This research explored drinking water wells that have detectable levels of arsenic and nitrate in disadvantaged vs. non-disadvantaged communities in San Joaquin County. The CalEnviroScreen 3.0 program and Groundwater Ambient Monitoring Program (GAMA) are used to measure disadvantaged communities and water quality data respectively. The CalEnviroScreen 3.0 scoring formula is used to calculate which census tracts are disadvantaged based on indices that measure pollution burden and population characteristics. The scoring is then combined with a census tract layer using Geographic Information Systems (GIS) technology. The disadvantaged community data are overlaid with GAMA groundwater well data to locate which communities are …

1998 - Salinas Valley Water (Preliminary Analysis Of) The Cause And Cost Of Seawater Intrusion

Miscellaneous Monterey and San Luis Obispo County Documents and Reports

An analysis of the historical cause of seawater intrusion in the Pressure Area of Monterey County. An annual overdraft of groundwater resources near the coast coupled with a seasonal cycle of over pumping created a reversal in the groundwater gradient and associated cones of depression. "Marine intrusion has occurred in the 180-foot aquifer in recent years as a result of overdrafts." (Bulletin 52, 1946, p.27). The only overdrafts on groundwater in the Salinas Valley were in the East Side and Pressure Areas. "There was no shortage of groundwater in the remainder of the basin and no threat of deficiency under …
