Background & objectives: One of the biggest concerns about the increasing development of the mining industries, especially in the dry and tropical regions, is their high water consumption and, consequently, the serious threat to the local water resources as well as the impacts of these industrieschr('39') pollution on the environment and other downstream water resources. Therefore, it is necess...

Male rats were given daily sessions during which a palatable saccharin solution was available. Based on intakes averaged over 3 days, groups with low, intermediate, or high intake of saccharin were formed. These rats were then given daily sessions in which alcohol (2-8%) or water were available. Initially, sessions were conducted with rats on a food restriction schedule; in later sessions, food...

Several cultures of north-central Nigeria do not use community cemeteries. Instead, human remains are buried in and around family compounds, often in shallow and sometimes unmarked graves. At several locations, graves and drinking water wells end up too close to be presumed environmentally safe. This paper reports findings of a pilot study that explored the potential for groundwater contaminati...

The prevalence of water quality incidents and disease outbreaks suggests an imperative to analyse and understand the roles of operators and organisations in the water supply system. One means considered in this paper is through human reliability analysis (HRA). We classify the human errors contributing to 62 drinking water accidents occurring in affluent countries from 1974 to 2001; define the ...

The use of population-level indices to estimate individual exposures is an important limitation of previous epidemiologic studies of disinfection by-products (DBPs). We examined exposure misclassification resulting from the use of system average DBP concentrations to estimate individual-level exposures. Data were simulated (n=1000 iterations) for 100 subjects across 10 water systems based on th...

Ground water is one of the main source of drinking water in Nanded city. City has witnessed a tremendous increase in population. This has lead to establishment of new colonies. A large section of residents live in the newly established crowded colonies under unhygienic conditions. The public bore wells, located in these areas are the main source of drinking water The present study was carried o...

In 1974, President Gerald Ford signed into law the Safe Drinking Water Act, the first piece of legislation of its kind to provide a comprehensive regulatory framework for overseeing the nation's drinking water supply. The law has proven instrumental in setting standards for ensuring that the US population can access drinking water that is safe. However, the law delegates much of its monitoring ...

Water intake was described and quantified in samples of urban Guatemalan schoolchildren stratified by gender and socio-economic status. The frequency of consumption and quantity of plain water drinking was estimated from one-day pictorial registries of all beverages, foods and snacks consumed over a 24-h period collected from 449 3rd and 4th graders from two social classes: 230 from higher SES ...
