Community public supply based Hydrogeologic Mapping Units A seamless map of the major groundwater areas used by community public supply wells in the United States was needed in order to describe and compute the number of equivalent people using public supply water. This goal was met by the delineation of hydrogeologic mapping units (HMUs). An HMU is a mapped polygon, within which, all public supply wells have a common source of water. The source of water can be either a national Principal Aquifer (PA) as defined in USGS (2003) or a Secondary Hydrogeologic Region (SHR) as defined in Belitz et al. (2018). Collectively, both PAs and SHRs are referred to as Hydrogeologic Regions (HRs). The common source of water can be a single HR or multiple HRs, as HRs can overlap one another....

An extensive archive, estimated to contain more than 3,500 historical (1925–2020) geophysical logs collected in conjunction with past studies conducted by various entities, and more than 2,000 additional donated well and geophysical logs are stored in hard-copy at the Central Texas Branch of the Oklahoma-Texas Water Science Center (OTWSC) located in Austin, Texas. This dataset addresses the need to preserve these records electronically by providing a scanned and indexed collection of 6,058 of these records in Portable Document Format (PDF) along with a public Microsoft Access database and comma-separated values (CSV) text file containing...
