Activities of 228Ra, 226Ra, 224Ra, and 223Ra, as well as 228Th are included in this dataset. Concentrations of dissolved organic carbon (DOC), total dissolved nitrogen (TDN), ammonium (NH4), nitrate + nitrite, nitrite, nitrate, dissolved inorganic nitrogen (DIN), dissolved organic nitrogen (DON), phosphate, chloride, sulfate, total dissolved iron, hydrogen sulfide, dissolved inorganic carbon, methane, and nitrous oxide are included. The radium data are stored in 4 .csv files, one for each study site. The other geochemical data are stored in 4 separate .csv files, again one for each study site. These data were collected in support of a study that was intended to quantify the rate of groundwater discharge from several shallow, coastal aquifers into adjacent estuarine systems. The fluxes of various geochemical constituents dissolved in the groundwater were also calculated from the groundwater discharge rates.
