“…The PET containers and stoppers were thoroughly washed with distilled water for three times and once with the water to be sampled before collecting the actual sample. As was described by Owamah et al (2013), Khan et al (2012), at each site, one bottle was filled with water having no acid while the other bottle was filled with the water from the same point and acidified by adding a few drops of 5 % HNO 3 to stop the activities of microorganisms. At the same time, samples for microbial analysis were collected using autoclave-sterilized sample bottles from the same locations .…”

“…As described in APHA (1992), chloride was determined by titration. Ultraviolet spectrophotometer screening method was used in the determination of the major anions by strictly following the method described in APHA (2012) using a UV spectrophotometer (DR 2800, HACH, Washington, USA) (Khan et al 2012;Owamah et al 2013). In order to ensure that the analyses were reliable and reproducible, blank, standard, and pre-analyzed samples were analyzed after every 10 samples .…”

This study was aimed at establishing a water quality database in the study area where none existed previously. Groundwater samples from bore-holes, hand-pump, and hand-dug wells of four densely populated towns in SouthWestern Nigeria were analyzed in respect to physicochemical factors, biological factors, and the metals Nickel (Ni), Lead (Pb), Cadmium (Cd), Zinc (Zn), Copper (Cu), and Iron (Fe) for six consecutive months from September 2012 to February 2013 to give mean values for each town and water source. Total aerobic plate, total coliform bacteria, and Escherichia coli (E. coli) were detected in most of the water samples from the different towns and sources considered. Except for total suspended solids and total solids, the physicochemical parameters of all the samples were within permissible limits. The concentrations Pb, Ni, Cr, and Cd were above the minimum permissible limits. The presence of coliforms and E. coli in the groundwater samples indicates fecal contamination. The microorganisms isolated in this study include Enterobacteriaceae, Staphylococcus aureus, E. coli, Citrobacter, Klebsiella, Pseudomonas, Bacillus, that bore-hole water samples were safer for drinking that water samples from hand-pump, and hand dug wells across the communities.

“…However, excessive power consumption or use of chemical agents such as coagulants, flocculants, pH stabilizers and disinfectants not only impact consumer health, but generate environmental loads as well (Khan et al, 2013;Mery et al, 2013;Ribera et al, 2014). This has generated significant social and industrial interest in developing new strategies aimed at Rev.…”

There is currently great concern about the processes that directly or indirectly contribute to the potential for global warming, such as stratospheric ozone depletion or acidification. In this context, and provided that treated water is a basic public utility in urban centers around the world as well as in some rural areas, its impact on the environment is of great interest. Therefore, this study applied the environmental methodology of Life Cycle Assessment (LCA) to evaluate the environmental loads of four potable water treatment plants (PWTPs) located in northeastern Colombia following the international guidelines delineated in ISO 14040. The different stages of the drinking water process were thoroughly assessed, from the catchment point through pumping to the distribution network. The functional unit was defined as 1 m 3 of drinking water produced at the plant. The data were analyzed through the database Ecoinvent v.3.01, and modeled and processed in the software LCA-Data Manager. The results showed that in plants PLA-CA and PLA-PO, the flocculation process has the highest environmental load, which is mostly attributable to the coagulant agent, with a range between 47-73% of the total impact. In plants PLA-TON and PLA-BOS, electricity consumption was identified as the greatest impact source, with percentages ranging from 67 to 85%. Treatment processes and techniques, bioclimatic conditions and culturally driven consumption behavior varied from region to region. Furthermore, changes in treatment processes and techniques are likely to affect the environment during all stages of a plant's operational cycle.Keywords: climate change, environmental impact, treated water. Avaliação do ciclo de vida de quatro estações de tratamento de água potável localizado no nordeste da Colômbia RESUMO Atualmente, existe uma grande preocupação com os processos que direta ou indiretamente contribuem para as alterações climáticas, destruição da camada de ozônio ou acidificação, entre outros impactos ambientais. Neste contexto, e desde que a água tratada constitui um serviço público básico em centros urbanos de todo o mundo e em algumas áreas rurais, o impacto de suas emissões no meio ambiente tem sido considerado de grande interesse. Assim, na pesquisa atual foi aplicada a metodologia ambiental de avaliação do ciclo da vida (LCA) para avaliar os impactos ambientais de quatro estações de tratamento de água potável (PWTPs), localizadas no nordeste da Colômbia seguindo diretrizes internacionais da ISO 14040. As diferentes etapas do processo de purificação a partir do ponto de captação por meio de bombeamento para a rede de distribuição foram completamente avaliadas. A unidade funcional foi definida como 1 m 3 de água potável produzida na fábrica. Os dados foram analisados com base no banco de dados Ecoinvent v.3.01 e processados no software LCAData Manager. Os resultados possibilitaram determinar que em plantas PLA-CA e PLA -POR, o processo de floculação tem a maior carga ambiental, o que é principalmente atribuível ao agente ...

“…In Pakistan over 40% of urban deaths are linked to waterborne diseases originated due to consumption of contaminated water [5]. A study conducted in Charsadda district of Khyber Pakhtunkhwa revealed that drinking water polluted with coliform bacteria was the main reason of common waterborne diseases like diarrhoea, gastroenteritis, dysentery and viral hepatitis in the region [6].…”
