Abstract Regression analyses of major ion concentration, and specific conductance were compared on a decadal basis from field data of the 1960s, 1980s, 1990s, 2000s, and 2010s to find if there is a statistically significant increase in calcium, chloride, and sodium compared to other major groundwater ions in the Middle and Lower Passaic River Basins. Time series graphical analyses, bivariate coefficient relationships, statistical prediction interval evaluations, and multivariate analyses were used to determine the significance of the individual ion concentration trends. Through ArcGIS, bedrock geochemistry was examined in correlation with well locations, ion concentrations, and road placements. GIS was used to create groundwater flow maps using previously collected hydraulic head measurements. Time series analyses for the Middle Passaic River Basin indicated that sodium and chloride levels are increasing at different rates throughout the study period.
