[4] V_pop_hexpoly.zip - Zip file containing shapefile of groundwater dependent populations served by domestic wells in locations highly vulnerable (V ≥ 0.5) to groundwater contamination from unconventional oil and gas development. Shown as Figure 3 in journal manuscript. Attributes: Population - Total vulnerable population within hexagon (number of individuals); Pct_TotPop - Total vulnerable population divided by Total population within hexagon (%); V_mean - Mean vulnerability to all UOGD, aggregated from original 250-m x 250-m grid computations; n_UOG - Number of UOGD wells within hexagon; n_spill - Number of UOGD spills within hexagon
