Milwaukee's ozone upgrade
Article Abstract:
Inactivation of Cryptosporidium, after the gastrointestinal illness caused by the microorganism in Milwaukee in 1993, involves the use of ozone in the treatment of water. A four-pronged approach was used for developing Milwaukee's ozonation facilities. Apart from being the only disinfectant that can kill Cryptosporidium at acceptable levels, ozonation prevents the formation of chlorinated disinfection by-products in water. It also improves filter performance for public drinking-water supply for potable water. The three primary applications in ozone application is discussed.

Newport news: brackish water gets fresh
Article Abstract:
The Newport News Waterworks in Virginia opted to treat brackish groundwater using the reverse osmosis (RO) process to meet rising water demands. Brackish water will be drawn from deep aquifers which are less vulnerable to drought or contamination compared to surface water. The water will then be passed through RO membranes to eliminate contaminants such as dissolved solids, organics, bacteria and color.

Making a map of public health hazards
Article Abstract:
The Exposure-Dose Reconstruction Program was initiated by the Agency for Toxic Substances and Disease Registry to determine the degree and amount of contaminants inhaled or ingested by people in a town in Somers, CT. The project utilized innovative computational approaches and simulation tools. These techniques allowed the project to reproduce and estimate past contaminants concentrations.
