Introduction to Applied Karst Hydrogeology
Instructor: Chris Groves, PhD, University Distinguished Professor of Hydrogeology, Director
Karst aquifers, commonly developed in especially soluble bedrock such as limestone and dolomite, provide challenges to water resource development and protection. Water is often lacking at the surface, and groundwater is typically highly vulnerable to contamination. Some traditional hydrogeologic methods so useful in porous media flow systems, including numerical modelling and use of monitoring wells, can have limited utility in karst systems and other, specialized methods are often called for.
Dye Tracing Tools and Techniques: Part 1
Instructor: Autumn Singer, MS, Research Hydrologist, Laboratory Manager
Join the master class of dye tracing! This session presents the technical aspects of dye tracing from initial considerations to injection and sampling to interpreting the results of your tracer study. Dye Tracing Tools and Techniques Part I will cover fundamental concepts of dye tracing and preliminary data to collect in preparation for groundwater investigations. Topics include: desktop investigation of the study area, karst hydrologic inventories, study area delineation, selection and installation of monitoring sites, background monitoring, and matrix interference investigations.
Dye Tracing Tools and Techniques: Part 2
Instructor: Lee Anne Bledsoe, MS, Research Hydrologist, Assistant Director
In this session we will build upon concepts presented in Dye Tracing Tools and Techniques Part I and address some of the most frequently asked questions about tracer test design and execution. During this hour, we will discuss and demonstrate qualitative versus quantitative sampling, dye selection and dosage, dye injection techniques, avoiding cross contamination, and data interpretation.
Dye Tracing Applications: Case Studies From the US
Instructor: Lee Anne Bledsoe, MS, Research Hydrologist, Assistant Director
As a wrap-up for the webinar series, we will explore several groundwater investigations in detail. Case studies will include examples of identifying leaks at reservoirs, contaminant source tracking, remediation pilot studies, water resource management, and tracing for environmental assessment and planning. These various applications require different considerations as to local site conditions, study objectives, and the specific tracing methods utilized. We will also discuss how water quality and hydrologic monitoring informed these studies.
