Biodeterioration of asbestos cement (AC) pipe in drinking water distribution systems

Epidemiology study of the use of asbestos-cement pipe for the distribution of drinking water in Escambia County, Florida.

Cancer mortality for the population census tracts of Escambia County, FL, which use asbestos-cement (AC) pipe for public potable water distribution, was compared with cancer mortality data collected from census tracts in the same county where other types of piping materials are used. An analysis of covariance was run to test for differences in standard mortality ratios for seven cancer sites am...

Asbestos Cement Drinking Water Pipes and Possible Health Risks - Review

Effect of pipe corrosion scales on chlorine dioxide consumption in drinking water distribution systems.

Previous studies showed that temperature and total organic carbon in drinking water would cause chlorine dioxide (ClO(2)) loss in a water distribution system and affect the efficiency of ClO(2) for Legionella control. However, among the various causes of ClO(2) loss in a drinking water distribution system, the loss of disinfectant due to the reaction with corrosion scales has not been studied i...

Survey the Nitrate Concentration in Drinking Water Distribution Systems of Kashan County, Iran

High concentration of nitrate is a prevalent problem in water resources. Untreated wastewater due to municipal, industrial and agricultural activities is the main potential source of nitrate contamination of groundwater and surface water. The maximum permissible level of nitrate concentration has been established to be 45 mg/L by WHO and US–EPA. Health problems, such as Methemoglobinemia in bab...
