- Sites are geographically depicted in Fig. 1; Allocation of sites to Group is provided in Table 1; Sites labeled as Group 1 are within a ‘minimally impacted catchment zone’ (=MICZ), whereas sites labeled as Group 2 are within a ‘potentially impacted catchment zone’ (PICZ) that contains a significantly greater density of unconventional natural gas (UNG) wells; Forest, Pasture, and Urban represent arcsin transformed values originally recorded as percentage within a 1 km2 radius of the catchment area; F-value is the F-statistic recorded in a 1-way analysis of variance (ANOVA) by Group [i.e., = MICZ (1) versus PICZ (2)] as derived in R [41]; Probability represents statistical significance of each F-value determined by Bonferroni adjusted alpha = 0.017, with significance indicated by ana
