Identification Of Patterns And Controls Of The Distribution Of Groundwater Discharge To Streams, Curtis Gebhard

All Theses

Groundwater discharge is a key component in understanding the interaction between groundwater and surface water. It provides baseflow to streams and can transport nutrients and contaminants to related aquatic ecosystems. It can also influence fish behaviour, spawning, migration and provide areas of refuge during summer and winter months. There are a variety of techniques that are used to characterize the magnitude of groundwater discharge including seepage meters, field permeameters, and piezometers and manometers, however the controls for the magnitude and distribution of discharge remain poorly understood. The purpose of this study was to conduct field investigations complimented with numerical analysis …

Water Management Plan For The Town Of Perenjori, Mark Pridham

All other publications

The Rural Towns – Liquid Assets (RT–LA) project was established with the aim of integrating salinity, waterlogging and flooding control with development of new water supplies in wheatbelt towns, and where possible, finding ways of putting the excess water to commercial use. Following the identification of effective integrated water management strategies, these have been applied to the 15 Shires participating in the DAFWA led RT–LA project. This report summarises the outcomes from all scientific investigations undertaken for Perenjori. In addition it presents the water management options, a preliminary analysis of those options and the priority recommended ones. Due to the …

Assessment Of Groundwater Quality In An Abandoned Feedlot, Henderson County, Kentucky: Data Report, E. Glynn Beck, James S. Dinger, John Grove, Eugenia Pena-Yewtukhiw

Information Circular--KGS

A three-phase project investigated the influence of past and present agricultural practices on groundwater resources in the Western Kentucky Coal Field. Phase II concentrated on past practices, specifically those associated with an abandoned dairy feedlot and an old homestead. Results of phase II analyses are presented in this report.

Sources And Occurrences Of Nonpoint-Source Chemicals In Groundwater, Jackson Purchase Region, Kentucky: Data Report, E. Glynn Beck

Information Circular--KGS

Groundwater from the Jackson Purchase Region was sampled to investigate possible contamination by nonpoint-source chemicals. Conclusions drawn from the resulting data and methodology can be found in “Sources and Occurrences of Nonpoint-Source Chemicals in Groundwater, Jackson Purchase Region, Kentucky,” Kentucky Geological Survey Report of Investigations 22 (series 12), by R.S. Fisher and E.G. Beck.

Assessment Of Groundwater Quality In A Remediated Abandoned Feedlot, Henderson County, Kentucky: Data Report, E. Glynn Beck, James S. Dinger, John Grove, Eugenia Pena-Yewtukhiw

Information Circular--KGS

A three-phase project investigated the influence of past and present agricultural practices on groundwater resources in the Western Kentucky Coal Field. Phase III concentrated on an abandoned dairy feedlot that had been remediated. Results of phase III analyses are presented in this report.

Sources And Occurrences Of Nonpoint-Source Chemicals In Groundwater, Jackson Purchase Region, Kentucky, R. Stephen Fisher, E. Glynn Beck

Report of Investigations--KGS

Nitrate concentrations that exceed U.S. Environmental Protection Agency drinking-water standards have been reported in Jackson Purchase Region groundwater since the 1960's. More recently, other nonpoint-source chemicals such as pesticides and volatile organic compounds have also been found. The sources of these chemicals and the pathways by which they reach domestic groundwater supplies must be determined to protect human health and to design effective land-management practices.

To investigate the occurrence of nonpoint-source chemicals in Jackson Purchase groundwater, 60 wells were selected on the basis of geographic location, hydrostratigraphic unit penetrated, and well type (bored or drilled); distances to row crops, known …

An Evaluation Of Lead Concentrations In Surface Soils And Sediments Within Lytle Creek Drainage Basin, Harvey Clark Norton

Theses Digitization Project

This paper represents a master's project that is a preliminary surface soil survey of the Lytle Creek sub-Watershed, near Devore, California. The sub-Watershed is a recreational site within the San Bernardino National Forest. This study was undertaken to determine the concentration of lead and lead salts within the soils and sediments within the watershed, and to determine if these products pose a threat to the health of the local environment and human consumers from the watershed. Possible sources of lead contamination include natural background geology, contamination of historical use of gasoline with lead additives, and the presence of outdoor shooting …
