Getting to the nonpoint source with GIS
Article Abstract:
The Galveston Bay National Estuary Program is using geographic information systems (GIS) to studynon-point-source pollution at the bay. The GIS is used in mapping the bay's geography, studying land-use data, computing the amount of pollution and producing charts and graphs to present the results. Areas within the watershed that have the highest concentration of pollution can be pinpointed by using theGIS. These locations are given priority in plans for controlling pollution at the bay.

Chicago remaps itself
Article Abstract:
The Chicago Citywide Infrastructure Management System (CWIMS) project was initiated by the city government Chicago, IL, to improve the city's water, sewer, street and bridge infrastructure and identify potential infrastructure problems. The project involves the creation of a physical inventory database based on the official city map. This database will save geographic information system that will enable different city departments to synchronize their activities.

Greening of ground water
Article Abstract:
An innovative continuous-flow plant became operational in Sep, 1994, to clear ground water underlying the 85 acre Bofors-Nobel Superfund site in Muskegon County, MI, of 69 various organic and 24 metallic pollutants. The plant's treatment system combines ultraviolet oxidation with ammonia stripping as well as processes such as metal precipitation and carbon absorption.
