mlms---Multilevel Monitoring System (MLMS) data storage and processing for the U.S. Geological Survey Idaho National Laboratory Project Office

Package used to store and process data from the Multilevel Monitoring System (MLMS) used in wells within the U.S. Geological Survey (USGS) aquifer-monitoring network at the Idaho National Laboratory (INL) in Idaho. Supported by the U.S. Department of Energy (DOE), the USGS collected discrete measurements of hydraulic head at various depths from wells in the eastern Snake River Plain (ESRP) aquifer over several years. These measurements were derived from data on fluid pressure, fluid temperature, and atmospheric pressure. Each well was equipped with an MLMS, which included valved measurement ports, packer bladders, casing segments, and couplers. The MLMS facilitated monitoring at multiple hydraulically isolated depth intervals, reaching significant depths below the land surface. Additionally, groundwater samples were collected from these wells over multiple years and analyzed for various chemical and physical parameters.
