  • Magnesium in drinking water – a case for prevention?

    Studies in many countries have demonstrated a relationship between drinking water mineral content and the risk of death in cardiovascular disease (CVD). Particularly strong relationships have been found for magnesium and it has been suggested that magnesium be added to drinking water. The aim of this article is to evaluate the validity of this suggestion by reviewing information on possible ...

  • Challenges in the implementation of a national programme on drinking water

    Provision of safe drinking water is a challenging problem requiring immediate attention. The skewed distribution of rainfall, inefficient use of water, presence of a variety of contaminants, such as fluoride, arsenic, iron and salinity, in most of the sources, and pollution by various economic activities have been the factors responsible for inadequate resources against the increasing demand due ...

  • Effect of agro-activities on drinking-water quality in Bangladesh

    Fifty-nine samples of drinking water were collected from various locations in Bangladesh to assess the impact of agricultural practices on groundwater quality. The basic groundwater quality parameters, such as pH, total dissolved solids, iron, sodium, chloride, sulfate, fluoride and arsenic were analysed. In addition, the presence of excess fertilizers was monitored by measuring levels of ...

  • Analysing four of the most contaminated foodstuffs

    Food adulteration has been around since the Victorian times when cheese was often coloured with lead salts, beer and milk were watered down and flour was bulked out with chalk dust or ground bones [1]. Governments apply stringent legislation and quality standards to food products but the practice of adulteration, driven by greed and profit, is still seen. ...

  • Orthophosphate removal from aqueous solutions using drinking-water treatment sludge

    Drinking-water treatment sludge (DWTS) is a by-product generated during the production of drinking water where iron hydroxides are the main component of the sludge. The aim of the study presented here was to determine the effectiveness of using ferric sludge from two underground water treatment stations to remove orthophosphates from a model solution. The analyses were performed in static ...

  • Drivers for performance improvement originating from the Dutch drinking water benchmark

    The Dutch drinking water sector has been benchmarked every 3 years since 1997, and the sector has significantly improved performance since then. Based on interviews with CEOs and financial managers of drinking water companies five drivers for improvement as a result of this benchmark are identified: ‘learning effect’, ‘enhanced transparency’, ‘managed competition’, ‘avoidance of negative ...

  • Methodology for sampling drinking water discolouration loose deposits at low velocities

    The occurrence of discoloured water at the tap is one of the most frequent reasons for customers to complain. Water discolouration arises from the re-suspension of loose deposits (LD) that accumulate in drinking water pipes, due to velocity increase. Because of its typical brownish/reddish colour, discoloured water is traditionally perceived as a consequence of cast-iron pipe corrosion, even in ...

  • Use of anthropogenic gadolinium as a tracer for bank filtrate in drinking water wells

    Knowledge of the amount of bank filtrate in raw water is crucial for drinking water suppliers using water wells in close proximity to rivers, in particular if those rivers are strongly affected by anthropogenic activities, e.g. receiving effluents from waste water treatment plants. Analysis of organic micropollutants as tracer compounds is costly and time-consuming, and results may be biased by ...

  • Comparing electrochemical disinfection with chlorination for inactivation of bacterial spores in drinking water

    Drinking water disinfection techniques without the dosage of chemicals are regarded as more advantageous in terms of costs and practical use. Here we investigated the efficacy of electrochemical disinfection for inactivation of Bacillus subtilis spores – a model microorganism of highly resistant pathogens. The effect of electrochemical disinfection with ...

  • Factors influencing public perception and use of municipal drinking water

    Despite more stringent regulations concerning drinking water quality in many countries, the public is increasingly concerned about the safety of municipal tap water. For this reason, acquiring a better understanding of consumer perception of tap water is an important issue for water authorities and utility managers. In this study, water consumption choice and profile were investigated. The case ...

  • Early warning system to forecast maximum temperature in drinking water distribution systems

    Climate change poses new challenges in preventing the exceedance of the maximum allowed temperature in the drinking water distribution system (DWDS). The objective of this article is to evaluate the feasibility of forecasting the maximum temperature in the DWDS. Two options were analysed: (1) using the records of the last day as forecast for the coming 2 days and (2) using 2-day weather forecast ...
