This 2015 dataset includes water quality information for private drinking wells sampled in the Lower Portneuf River Valley (LPRV) aquifer located in Pocatello, Idaho. This dataset includes the spatial locations and measured concentrations of nitrate-N (mg/L), total dissolved liquid (TDS) (mg/L), chloride (mg/L), sulfate (mg/L), isotopes of dissolved nitrate-N (δ15N‰, δ18O‰), and isotopes of groundwater (δ2H‰, δ18O‰). Also included are measured concentrations of pharmacuticals and personal care products (PPCPs) found in drinking water. To protect homeowner anonymity we will not be providing these spatial locations, if you would like this information please contact Dr. Sarah Godsey godsey@isu.edu.
