Chapter 8.6, Problem 1A

Calculate the elevation of the water table at each well location and write the approximate elevation on the line next to each well. Next, use a colored pencil to draw smooth 10-foot contours that show the shape of the water table. (Start with the 1160-foot contour.) Use a pencil of a different color to draw arrows on the map to indicate the direction of the slope of the water table.

a. Toward which direction (downward) does the water table slope?
b. Referring to the site of the proposed water well, at approximately what depth below the surface should the proposed well intersect the water table?
