Groundwater wells are critical infrastructure with significant impacts on the environment, water availability, and economy. However, comprehensive data on the purposes, locations, depths, and construction of these wells are only collected by individual states. We have compiled a nationwide dataset of groundwater wells throughout the United States. The tabular dataset consists of all groundwater well data obtained from the states, containing over nine million records. A subset of this dataset was created that excludes wells located outside of the reported county or state, with over eight million records. Our dataset represents all known groundwater well locational data that states could release. The data made available by these datasets can serve as a critical tool for refining our understanding of how groundwater is accessed and used throughout the United States, and how it impacts different industries. / Master of Science / Groundwater wells are important structures that have a big impact on the environment, water availability, and economy. However, information about these wells, like why they are built, where they are located, how deep they are, and how they are constructed, is only collected by individual states. We have put together a dataset that includes information about groundwater wells from all across the United States. This dataset is in a table format and contains over nine million records. We created a smaller version of the dataset that only includes wells located within the reported county or state, which has over eight million records. Our dataset includes all the information that states have shared about the locations of groundwater wells. This data can be a valuable tool for improving our understanding of how groundwater is accessed and used throughout the United States, and how it affects different industries.
