Limestone aquifers are important sources of drinking water in many regions of the United States, including Ohio. Here, I characterize properties of a limestone aquifer using data from an observation well that was installed as part of the Mirror Lake Water Science Learning Lab on The Ohio State University campus in Columbus, Ohio. I integrate drilling observations, a gamma ray log, and borehole camera footage to identify geologic formations and conductive features within the limestone. I also analyze slug test and pump test results to determine aquifer hydraulic conductivity. I show that the hydraulic conductivity is comparable with other local measurements and within the range of many limestone aquifers from other regions. I present three months of water level, temperature, and specific conductivity data from the observation well to explore the factors that influence water level and water quality in the limestone aquifer.
