Comparing Groundwater Sampling Methods for Denitrification Assessment: A Focus on N2 and Ar Measurements

The dataset comprises analysis results (major ions, N2, and Ar concentrations) from groundwater samples taken in the Lower Rhine Embayment (Germany) to assess the impact of sampling methods on N2, Ar, and excess-N2 concentrations. The data is used in the manuscript \"Comparing Groundwater Sampling Methods for Denitrification Assessment: A Focus on N2 and Ar Measurements\" by Felix Fahrenbach and Thomas R. Rüde, which is currently undergoing review by Groundwater. The libraries tidyverse, psych, car, rstatix, and PMCMRplus need to be installed to run the R scripts. Running the Python scripts requires the following packages: numpy, pandas, scipy, statsmodels, and matplotlib.
