OBJECTIVE To describe public opinion relating to the fluoridation of drinking water in a sample of the Queensland population. METHOD Data were collected by means of a computer-assisted telephone interview survey from a sample of the Queensland population. Descriptive statistics and logistical regression were used to examine associations between variables. RESULTS Seventy per cent of the tot...

BACKGROUND Public health is at risk due to chemical contaminants in drinking water which may have immediate health consequences. Drinking water sources are susceptible to pollutants depending on geological conditions and agricultural, industrial, and other man-made activities. Ensuring the safety of drinking water is, therefore, a growing problem. To assess drinking water quality, we measured m...

Fifty sampling stations have been identified and water samples were collected from June to May 2008, to know the groundwater quality of Greater Visakhapatnam city using Water Quality Index. The samples were analyzed for the physico-chemical parameters like Temperature, pH, Conductivity, Total dissolved solids, Dissolved Oxygen, Hardness, Calcium, Magnesium, Alkalinity, Chloride and Nitrate. The...

Gastrointestinal illness (GI) has been associated with heavy rainfall. Storm events and periods of heavy rainfall and runoff can result in increased microbiological contaminants in raw water. Surface water supplies are open to the environment and runoff can directly influence the presence of contaminants. A time-stratified bi-directional case-crossover study design was used to estimate associat...

To improve the efficiency of screening for anti-Microcystis compounds, we planned to use algae-lysing bacteria that kill the organisms of water blooms. A two step-screening process was carried out, i.e., the screening of algae-lysing bacteria and the selection of anti-Microcystis producers from the bacteria. Sources for the isolation of the bacteria were a co-cultivated fluid of a water sample ...

Study of the ground water quality in Hodeidah is an essential ingredient for a healthypopulation. In this research, study of drinking water samples for eight water sources wells in theQuti field has been achieved. The purpose was to a certain the quality of water from thesesources, the physical properties such as pH, electrical conductivity (EC) and total dissolvedsolids (TDS), showed the varia...
