Assessment of Contaminated Sites
|About this case study||
Moving beyond location: Using GIS to assess risk.
Contaminated land, resulting from the improper use, handling, storage and disposal of materials containing hazardous substances, is one of the legacies of past and present industrialization and waste disposal activity. Recently, heightened environmental awareness and concerns about contamination have resulted in increased identification and regulation of these sites. This case study presents possible uses of data commonly available in most communities for assessing the potential impacts of contaminated sites on the environment and public health. After locating contaminated sites, this case study then examines their physical characteristics and the demographic data of the surrounding community. This enables investigators to answer basic questions regarding the level of risk, in addition to identifying potential stakeholders.
Classroom time can be supplemented with field trips.
In this case study, a field trip to assess sites of suspected contamination has been included. Water quality analyses, including pH and dissolved oxygen, act as indicators of impact.
This case study requires a basic understanding of geographic information systems and ArcView 3.x.If you are unfamiliar with either of these,we recommend you read our Training Manual and complete the accompanying exercises before proceeding with this case study.
