Wandiga SO. Critical Water Issues in Africa. Washington, DC: American Chemical Society; 2015. Abstract

Water scarcity, purity and delivery have become major challenges of humanity especially in Africa. Globally 748 million and in Africa 325 million people lack access to safe water. Water diseases kill 842,000 people annually. The majority of those who lack water live in rural areas. Africa is second to Australia in dryness but is home to 15% of global human population and has only nine percent of global renewable water resources. Most of Africa’s surface water has become polluted by human activities and its wells are becoming dry. Impacts of climate change and climate variability are making water scarcity more stressful.

Technologies used for water harnessing are outmoded and inefficient. Africa needs to modernize its water purification technology; it requires adopting new methods like roof, pavement and urban water catchment to recharge its declining ground water level. Provision of safe drinking water policy need to change from piped water to every home to supply of point of use technologies at every home. There exist some potential new technologies that still require further research. The chapter highlights some recent development of nanoscience materials in water treatment that give promise to future trends. Similarly, small scale water harnessing technologies are outlined for ground water recharge and drinking water

International Journal of Photocatalysis. 2015;19:204-211. Abstractphoto_catalytic_inactivation_of_escherichia_coli_using_titanium__iv__oxide-tungsten__vi__oxide_nanoparticles_composite.pdf

This work focused on synthesis of Titanium (IV) Oxide and Tungsten (VI) Oxide composite and testing the composite as a photocatalyst in deactivation of Escherichi coli in water. Modified wet chemistry method was used and the synthesized nanoparticles calcined at 575° C, taken through XRay Fluorescence and X-Ray Diffraction. The result showed a particle size diameter of 18.99nm. The nanoparticles photocatalytic inactivation efficacy of Escherichia coli in water was tested. 3M Petrifilms from 3M Microbiology Products, U.S.A., was used for Escherichia coli colony forming units’ counts. ATUV 8W G8 T5 lamp from PHILIPS emitting between 350-600nm was used as energy source. The catalyst reduced Escherichia coli count by log 3.415 at an optimum catalyst amount of 0.75 g/L at pH 7.3 using the Chick-Watson model for disinfection kinetics. This work proved that photocatalysis is a promising technology in water purification with possible and practical opportunities existing especially for small-scale point-of-use water purification units where potable water could be treated for disinfection of pathogens or trace priority pollutants remaining in water distribution network after conventional treatment methods. This work proved that nano particles can provide solutions in treatment of drinking water especially for poor communities living in the tropics.

Rodrigues AJ, Oyoo WS, Odundo FO, Wambu EW. "Socio-economic factors influencing the spread of drinking water diseases in rural Africa: case study of Bondo sub-county, Kenya." Journal of Water and Health. 2015;13(2):500-509. Abstract

Socio-economic and medical information on Bondo sub-county community was studied to help establish the relationship between the water quality challenges, community health and water rights conditions. Health challenges have been linked to water quality and household income. A total of 1,510 households/respondents were studied by means of a questionnaire. About 69% of the households have no access to treated water. Although 92% of the respondents appear to be aware that treatment of water prevents waterborne diseases, the lowest income group and children share a high burden of waterborne diseases requiring hospitalization and causing mortality. Open defecation (12.3%) in these study areas contributes to a high incidence of waterborne diseases. The community’s constitutional rights to quality water in adequate quantities are greatly infringed. The source of low-quality water is not a significant determinant of waterborne disease. The differences in poverty level in the sub-county are statistically insignificant and contribute less than other factors. Increased investment in water provision across regions, improved sanitation and availability of affordable point-of-use water purification systems will have major positive impacts on the health and economic well-being of the community.

Ongeri DM, LALAH JO, Wandiga SO, Wandiga SO, Michalke B. "Seasonal variability in cadmium, lead, copper, zinc and iron concentrations in the three major fish species, Oreochromis niloticus, Lates niloticus and Rastrineobola argentea in Winam Gulf, Lake Victoria: impact of wash-off into the lake.". 2012. AbstractWebsite

Trace metals Cadmium (Cd), Lead (Pb), Copper (Cu), Zinc (Zn) and Iron (Fe) were analyzed in edible portions of three main finfish species namely Lates niloticus, Oreochromis niloticus and Rastrineobola argentea sampled from various beaches of Winam Gulf, Lake Victoria, Kenya, in order to determine any seasonal and site variations and the results showed significantly (p < 0.05) higher mean concentrations of Cd, Cu, Zn and Fe during the wet season compared to the dry season for all the three species indicating the impact of wash-off into the lake during the rainy periods. The overall mean concentrations of the heavy metals (in μg/g dry weight) in all combined samples ranged from 0.17-0.40 (Cd), 0.47-2.53 (Pb), 2.13-8.74 (Cu), 28.9-409.3 (Zn) and 31.4-208.1 (Fe), respectively. It was found that consumption of Rastrineobola argentea can be a significant source of heavy metals especially Zn, to humans, compared with Lates niloticus and Oreochromis niloticus, if only the muscle parts of the latter two are consumed.

LALAH JO, chieng EZ, Wandiga SO. "Sources of heavy metal input into Winam Gulf, Kenya.". 2008. AbstractWebsite

Water and surface sediment from rivers Kisat, Nyamasaria, Nyando, Sondu-Miriu, Kuja, Awach, Yala, and Nzoia, which flow into Winam Gulf, were analyzed for heavy metals in order to assess the influence of the catchment activities on heavy metal input into the lake. Sampling was done both upstream and at river mouths where the rivers entered in to the lake. The mean sediment concentration of exchangeable cations (in microg/g) for Ag, Cd, Co, Cu, Mn, Ni, Pb, Sn, and Zn ranged from 0.01 to 263 (for Mn at Kuja). Ag, Cr, and Cd were poorly leachable with 0.1 MHCl but the other cations were found to be fairly exchangeable. Most exchangeable cations in sediment ranged between 2% and 20% of the total heavy metal content obtained by digestion with strong acid. The mean total dissolved metal (0.45 microm filter cut-off) and mean total sediment concentrations ranged from nd-16 (Ag), nd-8 (Cd), nd-23.3 (Co), nd-50 (Cr), 5-157.5 (Cu), 50-3276 (Mn), nd-54.1 (Ni), 7-93.6 (Pb), 25-219.5 (Zn) in microg/L and from nd-8.34 (Ag), 0.48-1.75 (Co), nd-1.78 (Cd), 2.92-5.36 (Cr), 3.90-150.2 (Cu), 133.5-7237 (Mn), 4.33-42.29 (Ni), 3.09-66.06 (Pb), 23.39-7.83 (Sn) and 23.39-350.8 (Zn) in microg/g dry weight, respectively. The rivers analyzed were found to be non-polluted in terms of sediment loads except river Kisat which was found to be polluted because of elevated levels of Pb, Mn, Cu, and Zn. Nyamasaria and Nyando were also found to have higher concentrations of Pb, Cu, and Zn than those reported previously in the lake sediment. The dissolved metal concentrations were acceptable by WHO maximum limits in drinking water except Mn which was above WHO limit in Kisat, Nyando, and Nyamasaria waters. Enrichment of Cd and Pb was found in all the river sediment samples with factors ranging from 2.12 at Kisat river mouth to 4.41 at Awach (for Cd) and from 1.49 (at Kisat river mouth) to 2.38 (at Nyando river mouth).

Two experimental models simulating the traditional storage conditions prevalent in Kenya, i.e. the open basket model and the modern wooden box model, were used to study the rate of dissipation and fate of malathion residues in maize grains and beans stored for periods of up to one year at ambient temperatures averaging 23°C. The grain samples were initially treated with 10·36 mg kg−1 of radiolabelled malathion dust prior to storage and portions analysed at regular intervals for malathion, malaoxon and the transformation products isomalathion, malathion α-monocarboxylic acid and malathion β-monocarboxylic acid using a combination of chromatographic, radioisotopic and mass-spectrometric techniques. The findings showed a gradual penetration of malathion into the grains in amounts which were slightly higher in maize than in beans irrespective of the method of storage. After 51 weeks of storage, 34–60% of the initial residues persisted in all the grains. The total residual levels were slightly higher in beans than in maize irrespective of the storage methods though the persistence was a little higher in the wooden box than in the open basket. The rates of dissipation of the pesticide from the grains decreased with storage time and followed a biphasic pattern. Applying first-order reaction kinetics, the following half-lives were obtained: maize grains stored in open basket: 194 days; maize grains stored in closed wooden box: 261 days; beans stored in open basket: 259 days; beans stored in closed wooden box: 405 days. Beans stored in the wooden box had higher levels of bound residues than those sampled from the open basket. This trend was similar in maize grains although the concentrations were lower. The analysis of malathion metabolites confirmed the degradation trend of the residues.
