"The KDWM agrees that characterizing sites in karst geologic settings can be difficult. Crawford and Associates (now the Crawford Hydrology Laboratory) has the highest credentials in the country for this type of study and analysis." --The Kentucky Department of Environmental Protection, Division of Waste Management |

Nicholas C. Crawford, Ph.D., is Director of the Crawford Hydrology Laboratory as well as a Professor in the Department of Geography and Geology and Director of the Center for Cave and Karst Studies at Western Kentucky University. He is also the Director of the Karst Field Studies Program offered each summer at Mammoth Cave National Park. His research deals primarily with groundwater contamination of carbonate aquifers, sinkhole flooding and sinkhole collapse. He was the recipient of 25 grants for karst hydrologic research, and was awarded Western's highest award for Outstanding Achievement in Research in 1985. In 1990, Dr. Crawford received the National Council of State Garden Clubs' distinguished Silver Seal Award for his contributions to the protection of groundwater.He was the 1994 recipient of the Honorary Life Membership Award of the National Speleological Society. In the spring of 1996, Dr. Crawford received Western's Public Service Award. He also received the 1998 AIPG Kentucky Geologist of the Year award in May of this year. He is the author of over 160 journal articles, book chapters, guidebooks and professional reports dealing primarily with karst groundwater problems and has been featured in Time, National Geographic, and The World Book Encyclopedia. |

Dr. Crawford regularly teaches the following courses: Hydrology, Hydrogeology, Water Resources, Applied Groundwater Hydrology. In addition, he teaches Karst Hydrology each summer as part of the Karst Field Studies Program in cooperation with Mammoth Cave National Park. This is a 5 1/2 day workshop dealing primarily with karst groundwater problems and the techniques used to investigate and treat these problems. Consultants and government employees primarily are among those that attend the workshop. Dr. Crawford has also directed several Karst Hydrogeology Workshops for the US EPA. Dr. Crawford has been actively involved in karst hydrologic research since 1970. His Ph.D. dissertation dealt with karst groundwater flow in the Grassy Cove-Sequatchie Valley area (a thrust-faulted anticline located in East Tennessee). The dissertation involved numerous dye traces to determine interrelationships between geologic structure, stratigraphy and groundwater flow in the steeply dipping rocks associated with the Sequatchie Thrust Fault. All four parts of his dissertation have been published by the Tennessee Division of Geology. Dr. Crawford started consulting in the area of karst hydrologic problems in 1975 while on the faculty of the Geology Department at Vanderbilt University. His consulting practice has grown over the years and he now typically works on around 25 projects a year. Crawford and Associates, Inc. includes a well-equipped laboratory for dye analysis. Fluorescent dye analysis is performed on a scanning spectrofluorophotometer (Shimadzu Model RF-5301 PC). The laboratory analyzes water, cotton and charcoal elutant samples for dye traces performed by various consulting firms and government agencies. Dr. Crawford has performed over 900 dye traces, most of which were associated with determining groundwater flow in contaminated carbonate aquifers. He has been employed as a karst consultant by government agencies including: US Environmental Protection Agency, Kentucky Division of Water, Tennessee Division of Geology and US Geological Survey. In addition, he has worked for large corporations including: Rockwell International, DESA, Big River Utilities, Kendall Corporation, Kentucky Agricultural Energy Corporation, General Growth Management Corporation, CSX Transportation, Velsicol Chemical Company, etc. Dr. Crawford usually subcontracts to Engineering and Environmental Consulting firms. |
