How to Have Fun with a Ground-Water Flow Model by Todd Giddings, Ph.D., P.G Everyone who has done it agrees: Operating a ground-water flow model is fun! We had 30 people attend the hands-on training session with our four new ground-water flow models at the Summer Field Conference. As you can see in the photograph, the model has both a sand aquifer and a bedrock aquifer, with several wells, a lake, two springs, and a leaky underground fuel tank and a malfunctioning septic system seepage bed. A small aquarium pump behind the model causes the ground water in the model to flow from right to left. Various colors of dye are used to make the ground-water flow visible and to simulate leaks from the tank, seepage bed, or well casing. You use a syringe to pump any well you select and reverse the flow gradients to clean up the “pollution” plume.
Plan on attending this presentation at the Winter Conference to see pictures of all of the flow patterns and well pumping and pollution scenarios that can be run on the ground-water flow models. Better yet, sign up for the hands-on training session at the end of Thursday afternoon and have some of the fun yourself. We want you to learn how to operate a ground-water flow model so you can take one of the four models owned by the PGWA and teach a group in your town about ground-water flow and proper well construction. The ground-water flow models make it easy and fun to tell a school class or local organization about ground water and your profession. So check the box on your Winter Conference registration form and come and get your hands wet and have some fun with us.
