Evaluating vulnerable locations in the city of Atlanta, GA drinking water distribution system for microbial intrusion and regrowth using an automated monitoring and sampling device
(Georgia Institute of Technology, 2013-04)The integrity of the drinking water distribution system (DS) is considered the final, and one of the most important barriers for providing safe drinking water. The City of Atlanta (COA) drinking water DS is typical ... -
Physical and Biogeochemical Patterns in a Saltmarsh/River System (Duplin River, GA)
(Georgia Institute of Technology, 2013-04)Salt marshes are among the most productive habitats on Earth, and constitute a critical interface between the land and the sea. These intertidal ecosystems are home to a unique assemblage of fauna and flora, and play in ... -
Harmful Algal Blooms and Toxin Production in Georgia Ponds
(Georgia Institute of Technology, 2013-04)Cyanobacterial toxins have been implicated in fish, wildlife, livestock and human mortality events. Cyanobacteria blooms, which often produce toxins, are exacerbated by hot, dry weather. The majority of Georgia, with the ... -
Power and Water in the Apalachicola-Chattahoochee-Flint: Understanding the Water Implications of Potential Electricity Pathways
(Georgia Institute of Technology, 2013-04)Electricity generation and water are strongly connected, with important implications. Water for cooling power plants accounts for over 40 percent of freshwater withdrawals in the United States, and for up to two-thirds in ... -
Retrospective Analysis to Quantify Migration of American Shad in an Impoundment on the Lower Susquehanna River
(Georgia Institute of Technology, 2013-04)We integrated several existing data sources (migration timing/behavioral, hydrological, variable power station operations, and a 3-D time-varying hydrothermal model) to quantify the migration of American shad, Alosa ... -
Development of a Molecular Monitoring Tool for Imperiled Herpetofauna of the Southeastern U.S.
(Georgia Institute of Technology, 2013-04)Molecular techniques have recently been demonstrated to be effective and efficient methods for detecting presence of species across a range of aquatic systems. The general method includes the isolation of environmental ... -
Public Perceptions of Water Availability and Receptivity to Water Conservation in Georgia
(Georgia Institute of Technology, 2013-04)This study investigated public perceptions of water availability in Georgia to identify factors that influence receptivity to water conservation technologies and practices. A receptivity model comprising four components – ... -
Modeling nitrogen in on-site wastewater treatment systems
(Georgia Institute of Technology, 2013-04)State regulatory agencies set standards for minimum lot size for homes on onsite wastewater treatment systems (OWTS) based on the expected nitrogen (N) load to groundwater. However, the data to support these standards are ... -
Implementing an integrated technologies approach to low impact development designs
(Georgia Institute of Technology, 2013-04)Selecting the proper stormwater treatment technology presents a number of challenges to site designers, regulatory agencies and other stakeholders alike. It is paramount for stormwater Best Management Practice (BMP) ... -
EPA scorecard, a catalyst for unified watershed management, a case study
(Georgia Institute of Technology, 2013-04)Chattanooga has completed their EPA Water Quality Scorecard and is using the analysis as a tool to shape the direction of policies, codes, tools, and standards. The Scorecard has put a spot light on the process of land ... -
Home rule as a mechanism for explaining state preemption of local CAFO regulations
(Georgia Institute of Technology, 2013-04)Recently, regulation of concentrated animal feeding operations (CAFOs) by local governments has been complicated by conflicting state Supreme Court. In Idaho Dairymen’s Association v. Gooding County, the Supreme Court of ... -
U.S. Geological Survey Site-Specific Water Use Database (SWUDS)
(Georgia Institute of Technology, 2013-04)The U.S. Geological Survey’s site-specific water use database (SWUDS) is designed to store permitted and non-permitted surface and groundwater withdrawals from source waters, water deliveries among water suppliers, and ... -
Impacts of Climate Change on Water Supply of Off- Stream Reservoir
(Georgia Institute of Technology, 2013-04)Climate change is attracting more and more attention in recent years. In order to evaluate the impacts of climate change on future water supply, we developed HEC-5 model that can simulate the operation of off-stream reservoir ... -
Comparison of Digital Filter Hydrograph Separation with Geochemical Separation
(Georgia Institute of Technology, 2013-04)Aquatic Stormflow is defined as flow resulting directly from a storm event, while baseflow is thought to be groundwater flow that continuously occurs, most predominantly during non-storm periods. While conceptually these ... -
High Density Lagrangian Sampling for Pathogen Source Identification
(Georgia Institute of Technology, 2013-04)In compliance to the Clean Water Act, each US state compiles a list of water bodies not meeting regulatory criteria. The most common impairment in US water bodies is elevated pathogens measured by fecal indicator bacteria ... -
Predicting the Impact of Climate Change on Salinity Intrusions in Coastal South Carolina and Georgia
(Georgia Institute of Technology, 2013-04)This paper summarizes findings from Water Research Foundation Project 4285, which was sponsored the Foundation and Beaufort-Jasper Water and Sewer Authority (Roehl et al. 2012). The project’s thesis is as follows. Coastal ... -
Risk-Based Contingency Plan Using Water Supply Reliability Modeling During Drought
(Georgia Institute of Technology, 2013-04)Climate change is predicting dryer conditions for the Southeastern United States. This will result in greater dependence on storage of raw water in lakes and reservoirs and produce greater variability in water levels as ... -
