1 GIS for Environmental Science ENSC 3603 Class 23 4/7/09

2 A GIS Example: Identification of Potential Landfill Locations The following example uses information from the Center of Advanced Spatial Technologies (CAST)

3 Landfill Location Description: The Four-County Northwest Arkansas Regional Solid Waste Management District requested CAST to conduct a GIS study to see if there were suitable areas within Northwest Arkansas to locate a regional landfill.

4 EPA Landfill Location Restrictions Airport Safety - Bird hazard Floodplains year flood Wetlands - Contamination Fault areas - Ground failure, landslides, structure damage Seismic impact zones - Ground failure, landslides, structure damage Unstable areas - Poor foundation, mass movement, Karst terrains EPA Solid Waste Disposal Facility Criteria Technical Manual

6 Landfill Location Criteria Criteria provided by the Management District: No landfills within the following: 1) 500 feet of water intake sites 2) 300 feet of incorporated areas 3) 2 miles of designated streams 4) 10,000 feet an airport 5) 12 miles of existing landfills

7 Landfill Location Criteria 1) No landfills within 500 ft of water intake sites These areas are small, look carefully Areas in Red Not Suitable

8 Landfill Location Criteria 2) No landfills within 300 feet of incorporated areas Areas in Red Not Suitable

9 Landfill Location Criteria 3) No landfills within 2 miles of designated streams Areas in Red Not Suitable

10 Landfill Location Criteria 4) No landfills within 10,000 ft of an airport Areas in Red Not Suitable

11 Landfill Location Criteria 5) No landfills within 12 miles of existing landfills Areas in Red Not Suitable

12 Landfill Location Criteria Areas not suitable based on criteria 1 through 4 Areas in Red Not Suitable

18 It is amazing how fast people learn when they are not insulated from the consequences of their decisions.” Thomas Sowell "My grandfather once told me that there were two kinds of people: those who do the work and those who take the credit. He told me to try to be in the first group; there was much less competition." - Indira Gandhi
