TEACHING GROUNDWATER AT OTTERBEIN UNIVERSITY, THE 15 YEAR EVOLUTION OF THE OTTERBEIN LAKE WELL FIELD

A unique groundwater teaching resource was established in 2008 at Otterbein University (née College); the Otterbein Lake well field. This presentation chronicles the evolution and growth of

the well field and how this resource was incorporated into curriculums and applications at Otterbein and beyond, extending collaborative opportunities to local and international groups.

The well field began as a scientific inquiry- when drained, why did Otterbein Lake have offset water levels? Six monitoring wells were installed to begin the initial investigation. This set of wells answered the first inquiry with solid data and a few lessons learned, the hard way.

As time progressed, groups including CSCC, NGWA and Ohio EPA became aware of the well field, and they began to use the wells for education, outreach and training. At first the main use was to train students and groundwater professionals regarding different sampling techniques using a variety of equipment available from local providers.

The next evolution involved constructing larger diameter wells to accommodate submersible pumps to create effective drawdown. When 10 gpm pumping rates could be maintained, hydraulic evaluations of the aquifer were readily achievable. Equipment was acquired and sustainable aquifer analysis became part of the curriculum.

The final evolution includes off-grid pumping thanks to the generous donation of an Otterbein Alum and his partner. The solar powered pumping system coupled with purchase of telemetry/internet-based monitoring equipment now enables students to participate in remote monitoring to assess sustainable, off-grid pumping operations at the well field.

All in all, a generation of students and ground water professionals have benefited from the hands-on learning facilitated through the Otterbein Lake well field. The new goal is to continue this unique resource into the future.
