Dissolved Gas Modeling Results for Groundwater Samples Collected in the Western Lake Michigan Drainages and Eastern Iowa Basins Study Areas of the United States: 2007, 2017
This data release contains the results from a study of the transport and transformation of nitrate in groundwater and streams across diverse glacial terranes within the Western Lake Michigan (WMIC) Drainages and Eastern Iowa (EIWA) Basins of the United States. The primary focus of the study was on how varying redox conditions influence the timing and delivery of nitrate to streams in agricultural watersheds. The data represents dissolved gas modeling results that were obtained from the Dissolved Gas Modeling and Environmental Tracer Analysis (DGMETA) software program. DGMETA was used to produce calibrated dissolved gas models that provide optimal recharge temperature, excess air, and excess nitrogen gas concentrations (mainly from denitrification) based on measured dissolved gases.
