Assessing the Risk to Groundwater from On-Site Sanitation Guidelines for

There has been encouraging progress with access to safe drinking water and sanitation in both rural and urban areas since the United Nations Water Decade of the 1980s. However, more than 1 billion people around the world still lack access to safe water supplies and more than 2.4 billion are without adequate sanitation. A substantial majority of these people live in Asia where the lack of sanitation provision is particularly acute. In Africa, over one third of the population still remains without access to safe water and sanitation, and many of these can only be served by groundwater. The need for renewed efforts to improve the situation is recognised in DFID's recently published water strategy paper - ''Addressing the Water Crisis - Healthier and More Productive Lives for Poor People''.

These guidelines are an important contribution to risk assessment and the avoidance of the contamination of groundwater supplies from on-site sanitation. They have been development as part of a project funded by DFID through the water component of the Infrastructure and Urban Development Division's Knowledge and Research Programme. | »

RWSN Handpump Survey 2013 Summary of Findings

Manual pumps have been used for centuries but this simple technology remains the mainstay of rural water supplies in many countries. The Handpump Technology Network (which later became RWSN) was set up in 1992 to promote collaboration and standardisation so that handpumps could provide more reliable and better quality rural water services.

This survey is aimed at practitioners in government, NGOs, private sector and development partners who are directly involved in rural water service implementation, or who are involved in the procurement of handpumps or spare parts (as either a buyer or seller). | »

Draft Review of the Household Arsenic Removal Technology Options

Arsenic is widely distributed element in the earth’s crust and ranks twentieth in elemental presence. As a Group V element, arsenic exhibits a broad range of chemical reactivity and it is commercially used in alloys with lead. Arsenic in natural water has been reported from several countries including Bangladesh, China, Chile, Ghana, India, Nepal, Rumania, Taiwan, USA and Vietnam. In India, arsenic pollution is mostly of geological origin. However, ground water pollution of anthropogenic origin - due to industrial or mining waste - has been reported from Chennai in Tamil Nadu and Rajnandgaon in Madhya Pradesh.
