About

The Crawford Hydrology Laboratory is a nationally leading laboratory for groundwater flow investigations with an emphasis on, but not limited to, karst landscape/aquifer systems. Established in 1979, we provide a range of technical, field, and laboratory services to a diverse, national and international clientele, including federal, state, and local agencies, environmental consulting firms, and individuals. We have extensive experience assisting clients with a variety of fluorescent dye tracing applications including groundwater basin delineation, sewage leaks, dam safety and remediation, contamination source determination, and spring protection. 

With over 40 years of combined experience and expertise, our staff offers cost-effective groundwater tracing solutions to help clients solve real-world environmental problems. We are available to assist clients at whatever level of engagement is needed. We can independently design, and manage complete groundwater investigations or simply provide supplies and analysis. We have provided training and experimental design services to assist clients in establishing projects, who were then able to conduct field work themselves and ship the samples to our lab. In these ways projects can be cost effective and we can custom tailor each project to the needs and resources of the client. We also offer expert opinion and reporting relating to karst hydrogeology for engineering and environmental projects.

Past clients include the National Park Service, Bureau of Land Management, U.S. Forest Service, and Army Corps of Engineers. In the past few years we have provided services to clients in 23 states plus Brazil, Canada, Italy, Jamaica, Mexico, New Zealand, and Peru.
