- Abstract
Introduction: Insufficient drinking water sources, quality and in some cases reduced cleanness are between the humanity key reasons of inevitable illness and mortality causing between two million to four million deceases per year. Materials and methods: The investigation results were obtained using membrane filtration method running water samples across two counties in UK last year. The rest of the sources provided are from lakes, reservoirs and rivers. The culture media plates were prepared in house or bought ready to be used for Pseudomonas aeruginosa, Escherichia Coli and Coliform Sp. Results and discussion: Findings of microorganisms in the freshwater sources were not surprising as almost all the sources can be contaminated through natural processes, although positive results for pathogen organisms were found on the locations where the contamination was more like to happen, like busy River canals or near animals grazing areas. The study results establish Pseudomonas and other microorganisms' contamination, through the membrane filtration method, in several samples taken from freshwater sources. In addition, in depth study made for the laboratory examination of some microorganisms, such Coliform sp., Escherichia Coli or Pseudomonas Aeruginosa, exactly for the premises where animals or industry are developing their activity. Between 2 to 10 colonies/100ml Escherichia Coli presence found in Wiltshire pond and Avon Canal of these samples. Most of these water sources are considered freshwater even if large activity going on by or on their location, so the outcomes of the study are revealing potential risks and what kind of future steps can be taken to improve the quality of the water. The contamination is spontaneously through the activity around the location, and cannot be considered as a continuous process, as the results of previous and further investigation found none or similar, but less colonies per sample. Conclusions: The outcomes of this study were obtained through the Pseudomonas and pathogens presence into local pond and Avon Canal.
