Symposium organised by IAH’s Dutch Chapter and the Netherlands’ Hydrological Society, 29 November 2006, Utrecht, The Netherlands Arsenic contamination of groundwater has occurred in various parts of the world, most notably the Ganges Delta of Bangladesh and West Bengal, India, causing serious arsenic poisoning amongst large numbers of people. It is a natural occurring high concentration of arsenic in deeper levels of groundwater, which became a high-profile problem in recent years due to the use of deep tube wells for water supply in the Ganges Delta. Parts of Thailand, Taiwan, Argentina, Chile and China have also been affected. (source)

Cette brochure sur l’eau, comme sa contrepartie ‘Des Solutions intelligentes pour l’assainissement’ (Smart Sanitation Solutions), relate des exemples d’innovations à petite échelle telles que la désinfection solaire de l’eau, l’emploi de filtres à eau efficaces et peu coûteux, le recours à l’irrigation goutte à goutte à bas-coût et l’utilisation de pompes manuelles fabriquées localement et cinq fois moins chères que les pompes importées. En adoptant ces technologies, les foyers défavorisés dans les zones rurales peuvent doubler, voire tripler leur revenu annuel. Les solutions à petite échelle ont montré qu’elles pouvaient être économiquement rentables. Installées en grand nombre, elles peuvent à la fois améliorer la santé publique, relancer la production agricole et générer des activités locales. C’est pourquoi la diffusion à grande échelle de ces technologies est essentielle. (source)

This booklet aims to help achieve the drinking water targets as stated in Millennium Development Goals 7: halving the proportion of people who don't have sustainable access to safe drinking water and basic sanitation. In 2009 some 884 million people still did not have access to an improved water facility. Experience shows that access to 'improved' water supply facilities is no guarantee for safe and reliable water. Especially in developing countries tap water can be unsafe, because of inadequate treatment, recontamination during transport or storage or at home. 'Point of use' and small-scale treatment is a promising strategy to improve access to safe drinking water, in particular for the poor. Recent studies show that PoU reduces diarrhea morbidity for children under 5 by 29 % and is more effective than source water treatment, piped water on premises and improved public water supply. All the more reason to provide those who advise on systems for home water treatment in rural areas with current information on simple methods to improve drinking water for households. This booklet, part of the Smart Water Solutions series, can help them decide which method is best for a specific situation and what effect can be expected with respect to reduction of harmful micro-organisms. It also gives some price indications and refers to specific websites for further information. This publication is a co-production of NWP (Netherlands Water Partnership), Aqua for All and Witteveen+Bos. (source)

This booklet on water gives examples of innovations such as the use of sunlight to purify water, effective low-cost water filters, low-cost drip irrigation and locally prodcued hand pumps that are five times cheaper than imported pumps. By usiing these technologies, poor rural families can double or even triple their annual income. The book is designed as a source of inspiration, rather than a 'how to' manual. This publication is a collaborative effort by eight organisations: NWP (Netherlans Water Partnership), Practica, Simavi, IRC, Agromisa, NCDO, Aqua for All, Partners for Water. (source)
