Program Summary:

Presented by:

Chris Groves, Ph.D., P.G., Director
Crawford Hydrology Laboratory
(Karst Groundwater Investigations Presentation)

Lee Anne Bledsoe, BA, RS, Lab Manager
Crawford Hydrology Laboratory
(Ground Water Dye Tracing Presentation)


As we conclude our 2015 webinar series, join us for a special two part webinar presented by Crawford Hydrology Laboratory.

Karst Groundwater Investigations
2:00pm - 3:00pm

Karst landscape/aquifer systems are estimated to covers some 15% of the earth’s ice-free land surface and supply as many as 25% of the world’s population with water resources.  At the same time there are difficult water supply problems both with access, as surface water can be lacking, and quality as what groundwater is available can often be easily contaminated.  Understanding and monitoring karst ground also requires specialized methods. This seminar discusses important methods to study karst groundwater including subsurface flow path mapping, high-resolution flow and water quality monitoring, and introduces concepts of qualitative and quantitative water tracing.    

Attendees will take away from this presentation:

  • An introductory understanding of karst aquifer/landscape system
  • Understanding of water-related environmental problems in karst systems
  • Methods to understand geometry and behavior of karst flows
  • Methods to monitor karst groundwater
  • Procedures for identifying subsurface flow paths
  • Procedures and case studies of karst system monitoring

Ground Water Dye Tracing: Applications and Methods
3:00pm - 4:00pm

Fluorescent dye tracing can be used to study groundwater movement in a variety of applications.  In some settings, including but not limited to karst aquifers, this methodology is usually the first step in obtaining information about aquifer characteristics to support monitoring, pollution prevention, and water resource management. This webinar will walk participants through the process of planning and conducting a dye trace, give recommendations on how to avoid common problems, and explain how to interpret tracer test results.

Attendees will take away from this presentation:

  • Example of applications – Dye tracing case studies
  • Step-by-step guide on how to conduct a dye trace
  • Free consultation on individual projects for webinar participants.
  • Increased knowledge of applications of fluorescent dye tracing
  • How to select a fluorescent dye and dosage for injection
  • Field procedures for dye injection, dye receptor exchange, sample storage/transport
  • Interpretation of qualitative dye trace results

Chris Groves, Ph.D., P.G., Director

Dr. Groves is the Director of the Crawford Hydrology Laboratory and a University Distinguished Professor of Hydrogeology at Western Kentucky University. He received a PhD in Environmental Sciences at the University of Virginia, and has since developed an active international research program in Hydrogeology, Geochemistry and Water Resources. He has worked collaboratively with Chinese scientists and students since 1995 to understand environmental problems in the extensive karst region of rural southwest China. In 2013 he was a Ministry-Level finalist for the People’s Republic of China Friendship Award, that country’s highest honor for foreign experts. Groves recently completed a five-year term as co-Project leader for the United Nations scientific program IGCP 598 “Environmental Change and Sustainability of Karst Systems, and in 2015 was invited join the Steering Committee of the International Geographical Union’s Karst Commission. Closer to home Groves has served on the Board of Trustees for the Kentucky Chapter of The Nature Conservancy, and has since 1981 been involved in study and exploration of the caves and surface landscapes of Mammoth Cave National Park. This has included service through the years as an expedition leader, Member of the Board of Directors, and Past President of the Cave Research Foundation.

Dr. Groves, who has more than three decades of experience in hydrogeologic study and research in karst systems, provides experienced oversight of the design, implementation, and interpretation of karst groundwater flow investigations for CHL.

Lee Anne Bledsoe, BA, RS, Lab Manager

Ms. Bledsoe is the manager for the Crawford Hydrology Laboratory. She communicates with clients and supervises all daily workings of the lab, including laboratory analysis, QA/QC, and field work. In her time with CHL, she has worked on dye traces for groundwater basin mapping, effluent and sewer pipe break investigations, dam leaks, landfill expansions, determining groundwater flow routes from factories and determining spring recharge areas.

Before joining the Crawford team in 2008, she worked for private research institutes and the National Park Service on water quality, hydrology, ecosystem restoration, and public health research projects. She is a Registered Sanitarian with the Department of Public Health for the State of Kentucky and is a certified onsite wastewater disposal inspector. Ms. Bledsoe received her B.A. in Environmental Science from Tusculum College and will be completing a Master of Science in Geoscience at Western Kentucky University in Fall 2015. Her thesis work is a collaborative effort with the United States Army Corp of Engineers to investigate groundwater flow in the vicinity of Patoka Dam in Indiana to support dam safety risk assessment.
