There are many trends in making an ecological city all around the word, one of important cases in this approach is safe and health water. According by definitions, safe and potable water is water needed for conducting the activities of man. Potable water is the most important renewable sources and this resource plays important role for survival of most living organisms as well as man based on s...

This study evaluated water quality of the Nissitissit River and Salmon Brook, located in southeastern New Hampshire and northeastern Massachusetts. Water samples were collected once a month over three consecutive months (June, July, and August – summer of 2007) at five locations in each river and analyzed for a group of chemical and microbiological parameters typically monitored to characterize...

The causes of term prelabor rupture of membranes (term PROM) remain poorly defined. The authors conducted a record-based prevalence study to explore a possible relation between disinfection by-products in drinking water and term PROM in an Australian community with spatially variable trihalomethane and nitrate levels. A multilevel statistical model was used to examine the relation between facto...

Johannesburg water is responsible for the supply and monitoring of drinking water supplied to the greater Johannesburg area. Part of this monitoring programme involves the determination of Trihalomethane (THM) levels and the comparison thereof against the limits stipulated in SANS 241. This paper demonstrates the approach used to determine the uncertainty of the analytical method associated wit...

Bacteriophages are regarded as enteric viral indicators in faecally contaminated water systems and may indicate the presence of human viral pollution. They are relatively resistant to inactivation by natural and treatment processes. In this study, the presence of somatic coliphages and F-RNA coliphages was investigated in potable water from rural areas in the North West province. Water samples ...
