Abstract:

Bottled water is now the biggest selling soft drink in Europe (van Musschenbroek, 1995) with sales topping 700 million litres in 1994 in the UK alone (Natural Mineral Water Association, pers comm). As part of a wide ranging UK Department of the Environment Programme to assess possible risks from the consumption of drinking water from all sources, a survey of the microbiological quality of still bottled water, at the point of sale, was conducted. A total of 17 different brands of still water (both natural mineral and other bottled water) in a variety of different containers (plastic and glass,

Abstract:

Microorganisms are the ideal indicators of the organic pollution of the surface waters because of their ability to promptly respond to environmental changes. Due to poor economic situation and lack of law implementation, most wastewaters in Serbia are released directly into a surface water recipient without any, or a limited, treatment. This practice has created numerous highly polluted surface waters in the region. Therefore, we conducted seasonal monitoring of the bacteriological quality of the Nišava River located in southeastern Serbia in order to assess the extent of its organic and faeca

Abstract:

Studies in Southern Africa have shown that even when microbiologically safe water is supplied to developing communities at communal standpipes, contamination by high numbers of pathogenic microorganisms may occur during the processes of fetching water from the supply source and storage during use at home, rendering such waters unsafe for human consumption. This study investigated the occurrence of biofilm in PVC storage containers as one possible reason for this deterioration, using heterotrophic bacteria and total coliform counts as well as turbidity as indicators.

The applicability of reclaimed water for any particular use depends on its physical, chemical, and microbiological quality. The effects of physical and chemical parameters for nonpotable uses of reclaimed water are, for the most part, well understood and criteria have been established.

Abstract:

The legislation from the European Commission and various other guidelines are discussed in the context of microbiological standards for drinking water. Difficulties in applying these standards are identified and reference is given to the quality control procedures adopted by Anglian Water. Pressures to achieve other drinking water standards, especially trihalomethanes, and the possible need to achieve higher microbiological quality objectives than those regulated currently, could lead to major changes in UK treatment practice.

Abstract:

This paper summarises the physicochemical and microbiological quality of water from a rainwater harvesting (RWH) system in a UK-based office building. 7 microbiological and 34 physicochemical parameters were analysed during an 8 month period. Physicochemically, harvested rainwater quality posed little health risk; most parameters showed concentrations below widely used guideline levels for drinking water. However, RWH system components (e.g. fittings and down pipes) appear to be affected soft water corrosion, resulting in high concentrations of some metals (copper, zinc and aluminium). This su
