Use the data in the BlaCkHIlls folder and SturgI883 geodatabasc to answer the lollowmg questions.
1. The Madison Limestone is an important aquifer. Citizens are concerned about gas or A
chemical trucks overturning on roads and causmg contamination. What is the total length 0!
roads crossing the Madison, in kilometers?
2. The infiltration rate of the geological substrate is a strong factor in evaluating the spill
I hazards for roads. Create a map of all the roads based on the infiltration capacity of the
geology, using appropriate symbols to indicate hazard. Capture your map.
3. The use of a road is another factor in evaluating spill hazard. Create a field containing a
hazard rating for each road based on both infiltration and use. For use, give primary roads a
value of 3, secondary roads 2, and primitive roads 1. What is the range of values for the
index? Create a map of the roads based on the hazard index. Capture the map.
Rangeland can cause significant impacts on surface water quality. Using the Iulc and
