Due to inappropriate and inadequate urban sanitation infrastructure in Ghana wastewater from households and other facilities ends up in nearby water bodies, which are often used as sources of irrigation water. However, this practice could have adverse public health and environmental effects, especially because untreated wastewater has high population of pathogenic organisms. The purpose of this study was to determine the current level of exposure of the Ghanaian local population to faecal coliform (FC) through the consumption of wastewater irrigated vegetables and to analyse and improve the effectiveness of common washing methods for the reduction of faecal microorganism populations on the surface of wastewater-irrigated vegetables. The levels of pathogen on market vegetables produced with wastewater were determined. Questionnaire interviews were also used to gather information on common methods used for washing vegetables in 11 cities in West Africa. The efficacy of the common decontamination methods was measured in terms of log reductions in FC populations on homogenised contaminated vegetable samples. High FC and helminth eggs contamination levels exceeding common guidelines for food quality were recorded on the market vegetables. Methods used to wash vegetables vary widely within and between Ghana and neighbouring francophone West African (WA) countries. However, several of the most common methods do not reduce the contamination to any desirable level. Significantly, different log reductions are achieved depending on the washing method and contact time. Tests to improve the apparent ineffective methods were especially promising in view of the relatively expensive vinegar. However, up to 3 log units reduction is also possible at a much lower price with ‘Eau de Javel’ (bleach), which is commonly used in francophone WA. Washing vegetables before consumption is important for health risk reduction. However, any washing method will need complementary efforts to reduce pathogen contamination.

This is a report on the fourth and final year of the RUAF-CFF programme activities in West Africa Anglophone region, coordinated by the International Water Management Institute (IWMI), Ghana. This report documents the activities implemented as well as the results, outcomes and impacts in all focus cities within the region from January 2005 to December 2008. The cities are: a. Pilot cities: Accra, Ghana, Freetown, Sierra Leone, and Ibadan, Nigeria in sequential order of entry and intervention; b. Partner (or dissemination) cities: Tamale, Tema and Cape Coast in Ghana; and Akure in Nigeria, all at completion stages of pilot project implementation in their respective cities.

Various water-dependent livelihoods depend on both domestic and surface water sources. In Accra, Ghana, investigation shows that the productive uses of domestic water, which are not intentionally planned as part of household water systems, appear to be significant in terms of numbers of direct and indirect beneficiaries, the contribution to household income and the services they provide to the city population. In general treated water quality is considered good for various purposes whereas the use of surface water is limited. Though surface water has some uses today, many other past uses have had to be dropped due to pollution. The pollution has been attributed to the manner of disposal of human excreta and solid waste by individuals, and institutional lapses, among others. The paper presents preliminary findings on various practices in water-dependent productive activities. It presents the perception of river water quality and the factors influencing current behaviour and how unfavourable behaviour can be changed. The goal is to deepen the understanding of the urban water planning process.
