ABSTRACT:

This companion resource to a published Water Resources Research paper contains the following hydrogeologic data: (i) 33 borehole data used to generate a 3D lithostratigraphic model (Figure S5); (ii) average hydraulic head data used for a groundwater flow model calibration (Figure S7); (iii) long-term barometric pressure corrected head data retrieved from pressure transducers (Figure S13c); (iv) arsenic time-series measurements for a subset of wells (Figure 6); and (iv) dissolved arsenic, methane, tritium, and sediment reflectance data displayed in Figure 12. All figures in the paper were generated using the open source programming language of R. An example R script to reproduce Figure 12 is provided.
