Aquifer Testing Workshop

 
 

Instructors:
Keith Halford and Tracie Jackson, U.S. Geological Survey

Groundwater flow rates and storage volumes cannot be measured directly and are estimated indirectly from aquifer-test results, which are controlled field experiments. Transmissivity and storage coefficient are principal results that define behavior of groundwater system in response to pumping. Volume of water displaced or rate of water pumped are the principal controls that allow estimation of transmissivity and storage coefficient by fitting analytical or numerical solutions to observed water-level changes.  

A 1-day, aquifer-test class will cover fundamental concepts of aquifer-system responses to pumping and slugging wells. Material will emphasize practical aspects of analyzing and interpreting slug test and single-well pumping aquifer tests. Field conditions and limitations will be considered for measuring water-level and discharge data. Expected ranges of aquifer properties and empirical correlations between specific capacity and transmissivity will be presented.  Design, interpretation, and limitations multiple-well aquifer tests will be presented. Guidance for reporting aquifer test results will be provided.

Data will be reduced, single-well tests will be interpreted, and simple problems will be analyzed during class exercises. 

Miscellaneous:
Participants are encouraged to bring laptop computers to the workshop.
