  • Water Quality Models

    ' In order to determine the impacts of a particular discharge on ambient water quality, it is usually necessary to model the diffusion and dispersion of the discharge in the relevant water body. The approach applies both to new discharges and to upgrading of existing sources. This note provides guidance on models that may be applicable in the context of typical Bank projects.' Introduction ...

  • Water quality measurement extreme

    Background The characteristics of the Rio Tinto in the south-west of Spain, near Sevilla, are his ruby colour and the extremely sour pH-value between 0 and 2 pH-units. The river carries a mixture between poisonous heavy metals like copper, nickel, arsenic, iron and cadmium, dissolved in high-percent sulphuric acid. It’s not proved where these unusual conditions come from. As per current ...

  • Ensuring Water Quality in Africa

    Water is essential for life, and “access to safe water is a fundamental human and, therefore, a basic human right.” With this statement and his address on World Water Day in 2001, United Nations Secretary-General Kofi Annan put a spotlight on what continues to be a global problem: clean water.

  • European bathing water quality in 2012

    Every year, millions of Europeans take advantage of the continent's wonderful selection of beaches, rivers, and lakes for a relaxing holiday or a day out. It is vitally important that they know the quality of the water they are swimming in, and that they do not jeopardise their health. The European Environment Agency (EEA) and the European Commission hope that this year's bathing water report ...

  • Optimal sampling network for monitoring the representative water quality of an entire reservoir on the basis of information theory

    This study presents a method for optimal selection of sampling stations for representative and effective water quality monitoring of a reservoir on the basis of information theory. We adopt an objective function used for the design of other hydrological monitoring networks such as rain gauge networks. Unlike rain gauges, in which only a single variable of rainfall is of interest, water quality ...

  • Organisational arrangements and drinking water quality

    This paper discusses the findings of a research project which explored the impact of varying organisational arrangements on drinking water quality in England and Wales, and the Republic of Ireland. It is established that drinking water quality has been of a consistently higher standard in England and Wales in comparison with the Republic of Ireland. It is also demonstrated that the associated ...

La Parguera is the site of a Special Marine Reserve and counts among its unusual habitats a phosphorescent bay, important ...

  • Impact of intermittent water supply on water quality in Lebanon

    Lebanon in general and its capital, Beirut, suffer from water shortage due to the increasing water demand and the lack of proper management despite its abundant water resources. An intermittent water supply strategy was implemented in order to minimise deficiency problems. This, however, can seriously affect water quality due to the potential suction of non-potable water by negative pressures, ...
