In this study I created a hydrological and geological profile across a series of private groundwater wells in Shreve, Ohio. I started by making a cross section of this area through well log data. I discovered that this consists of alternating layers of shale and sandstone, as well as varying depths of glacial deposits. These changes in sediment and bedrock allow for a distinct groundwater flow, as well as different extraction rates. By analyzing the topography of the greater Shreve area, I also identified the drainage basin for this aquifer and potential sources of surface water and groundwater interactions. To assess water quality, I sampled two private wells located above this aquifer, testing for major trace elements. I found that the water utilized by these residents of Shreve is mostly free of contamination; however, there is eight to nine times the accepted maximum concentration limit of thallium. Long-term exposure to excess thallium can result in adverse health effects, so I present possible mitigation strategies, as well as a new potential well site that could be utilized to maximize groundwater extraction while minimizing contamination levels.
