a) average depth-to-static level at the end of the assessment period, along with average net increase or decrease, measured in feet;

b) maximum and average depth of bedrock at the deepest point measured in feet;

c) total number of active index wells measured in whole numbers;

d) average distance between active index wells measured in miles;

e) average geographic distribution or density of active index wells measured in number per section of land;
