Residents of Ogoniland (pop. 832,000), in Rivers State, Nigeria, are demanding compensation and clean-up of the oil that has polluted water sources and destroyed their livelihoods. A UNEP study  published in August 2011, concluded that the environmental restoration of Ogoniland could take 25 to 30 years and would require an initial investment of US$ 1 billion contributed by the oil industry and the Government.
Communities relying on polluted wells should immediately be provided with adequate sources of drinking water, the UNEP study said. However, three months after the release of the study, only two of the ten communities where drinking water was found to be dangerously contaminated by oil had been provided with safe water, claimed Chris Newsom of Stakeholder Democracy Network.

Senegal’s Ziguinchor Region suffers from serious pollution of its groundwater by farm runoff and salinity, warned the head of the Regional Hydraulic Division, Lamine Bodian. This aggravates an already existing shortage of potable water. A joint effort by the United States Agency for International Development (USAID) and Senegal’s own potable water and sanitation program, PEPAM, has been addressing the problem in about 50 villages since February 2010. The programme, which will continue until 2014, is being funded by the US to the tune of 9.5 billion francs (around $20 million US) and carried out by the non-governmental group RTI International.

Buamah, R., Petrusevski, B. and Schippers, J.C. (2008). Presence of arsenic, iron and manganese in groundwater within the gold-belt zone of Ghana. Journal of water supply: research and technology-AQUA ; vol. 57, no. 7 ; p. 519-529. doi:10.2166/aqua.2008.149
About 45% of the total drinking water in Ghana is produced from groundwater. The presence of arsenic and manganese in groundwater above the recommended WHO drinking- water guidelines pose a threat to consumers’ health. To provide additional information on groundwater quality in the gold-belt zone of Ghana, nearly 290 well water samples from three regions namely Ashanti, Western and Brong-Ahafo, were analyzed for the presence of arsenic, iron and manganese. It was found that 5-12% of sampled wells had arsenic levels exceeding the 10 mg l-1-WHO provisional guideline value. Communities within the studied area with high arsenic presence in their groundwater are located within the Birimian and Tarkwaian geological formations. Most of these arsenic contaminated wells (70%) have been in use for more than 15 years. Brong-Ahafo, Ashanti and Western regions had 5%, 25% and 50% of wells, respectively with iron levels above 0.3 mg l-1, the drinking-water guideline value commonly accepted for iron. Thirteen percent of wells in Ashanti and 29% in the Western region exceeded 0.4 mg l-1-the WHO health-based guideline value for manganese.
