This map has locations of wells (lettered a to p), samples of river water (labeled r1 to r8), and samples of springs (labeled s1 to s4). various farms, factories, mines, and other facilities are also shown. only the roads (gray lines) and outlines of the facilities are shown, not the actual buildings and other details. colors (or shades of gray) on the worksheet represent in a general way the types of rocks and sediment exposed on the surface; check the cross section in the textbook for details. do the following: (1) draw on this map contours of water-table 8 a elevations and draw large arrows showing the direction of groundwater flow; (2) shade in areas of contamination and use the directions of groundwater flow and stream flow to determine which facilities caused the contamination; (3) draw a large x over these facilities; (4) draw circles around two wells that you predict will remain free of contamination; and (5) write the letter w to mark the location of new wells you propose to drill to intercept the contamination 2 reference the textbook for additional information n tes: (1) a recent geologic study has shown that slidetown and springtown are not sources of contamination, and (2) contamination can follow permeable units through the subsurface, but is less likely to travel through less permeable units even though the water table is shown as cutting across the units (which it does) o
