On-site sanitation systems dispose of human excreta, with or without treatment, on the residents' housing plot. Examples include pit latrines and septic tanks with drainage fields. This study reviews the risks to health posed by groundwater contamination from on-site sanitation (particularly latrines). Detailed understanding of groundwater contamination is complicated by a host of factors, broadly grouped into substantial and often unknown variations in subsurface conditions, […]
The water safety plan (WSP) approach is widely recognized as the most reliable and effective way to consistently manage drinking-water supplies to safeguard public health. Since the introduction of WSPs in the third edition of the WHO Guidelines for Drinking-water Quality (GDWQ) and the International Water Association (IWA) Bonn Charter for Safe Drinking Water in 2004, a significant number of water suppliers have implemented WSPs […]
Objectives: To estimate exposure to faecal contamination through drinking water as indicated by levels of Escherichia coli (E. coli) or thermotolerant coliform (TTC) in water sources. Methods: We estimated coverage of different types of drinking water source based on household surveys and censuses using multilevel modelling. Coverage data were combined with water Quality studies that assessed E. coli or TTC including those identified by a systematic review (n […]
The impact of onsite sanitation on water resources has been the subject of much study with regard to conventional septic tanks and soak-aways. However, research of impacts from rural and peri-urban communities using pit latrines, particularly in underdeveloped countries, has been unconvincing. With the increase in the extension of sanitation services provided by the South African Government anticipated to result in the establishment of some […]
This regional strategy was developed in 2012 during the nutritional and food crisis in the Sahel. It was updated in 2015. Revised during the 2014 consultation process, it remains an intersectoral guidance strategy that can be adapted to the specific national and local features of each country.

This comic introduces children to water and the environment. The little waterdrop called "Droppy" gets itself into adventures which give the reader an indea of the water cycle, wasting water, water pollution and others. It gives special attention to groundwater. Although these stories are happening in different cultural regions in this comic, these are problems which are happening daily in many parts of our world. We […]
The discharge of domestic wastewater to ground and the proximate abstraction of groundwater for domestic purposes can contaminate drinking water. Regional councils need to consider these situations when implementing the National Environmental Standard (NES) for Sources of Human Drinking Water (NZ Government, 2007). Separation distances between wastewater discharges and groundwater abstractions must be established to reduce the likelihood of contamination. Some regional councils have specified […]
Background: Pit latrines are one of the most common human excreta disposal systems in low-income countries, and their use is on the rise as countries aim to meet the sanitation-related target of the Millennium Development Goals. There is concern, however, that discharges of chemical and microbial contaminants from pit latrines to groundwater may negatively affect human health. Objectives: Our goals were to a) calculate global pit […]
In recent years, there has been growing scientifc evidence implying a close link between the lack of WASH and stunting. Stunting, which means low height for age can be a marker of a whole range of developmental setbacks of children including cognitive impairment.
La situation de l’assainissement et de l’approvisionnement en eau potable des quartiers non lotis et périphériques des communes urbaines du Burkina Faso n’est pas suffisamment connue et rend difficile la planification des différents programmes et projets dans ces zones. En effet, il n’existe pas pour le moment d’informations précises sur l’AEPA des populations vivant dans ces zones. Pour remédier à cette insuffisance au niveau de […]

Short description of the project: The grant was awarded to the Pollution Research Group (PRG) at the University of KwaZulu-Natal in order to increase the capacity of the PRG to […]
Water, sanitation, and hygiene can have a profound effect on health and nutrition. A growing base of evidence on the link between sanitation, child height, and well-being has come at an opportune time, when the issue of sanitation and nutrition in developing countries has moved to the top of the post-2015 development agenda.
