Water satisfies human needs in many ways. Without water, life is not possible in this planet. According to the estimation of the WHO, 4,000 children die every day from water-borne diseases and this condition is worst in developing and under-developed countries. Water-borne diseases are caused by the consumption of contaminated water. Indeed, it is the main agent of transference of the pathogens causing these diseases. The main objective of this paper is ‘to identify the water-borne diseases and their challenges and to suggest remedial measures to overcome the challenges in the study area’. Both primary and secondary data were used to conduct this study and the analysis of this study is tabulated clearly in the data analysis part. The coastal areas of Ampara District (Sainthamaruthu, Karaitivu, Maligaikadu Mawadipalli, Akkaraipattu, Irakkamam, Varipathanchenai, Addalaichenai, Palamunai, Oluvil and Nintavur) face a lot of challenges induced by water-borne diseases. Viruses, bacteria, parasites and protozoa are the main pathogens. Bacillary dysentery (shigellosis), cholera, other diarrheal diseases, hepatitis A and E and typhoid fever were identified as the most common diseases in these areas. The causes for the diseases are the contamination of water by improper drainage management, effluent contamination of water sources, over population and the lack of awareness among residents about water-borne diseases. According to the result of this study, controlling water contamination, constructing water purification systems, mending existing drainage systems, following instructions when constructing latrines, examining and remediating contaminated wells and providing awareness among residents are ways to attain the objectives.

The importance of fish farming can never be over emphasized because it’s a major provider of dietary protein, source of income and employment for the growing populations in Nigeria. Similarly, the importance of the bacteriological evaluation of fish pond water can never be over emphasized as it is a major indicator of the suitability and sanitary condition of the aquaculture pond and the fish in particular. This study evaluated the bacteriological profile of different fish pond water located within Owerri metropolis. A total of 10 fish pond waste water samples were collected and analyzed using different selective microbiological media and isolates identified using gram staining and biochemical reactions. Result shows that the total heterotrophic bacteria count ranged from 6.4×103 CFU/mL - 7.5×107 CFU/mL, total coliform count ranged from 2.1×104 CFU/mL - 5.6×107 CFU/mL, total vibrio count ranged from 2.7×103 CFU/mL - 5.9×105 CFU/mL while the Salmonella / Shigella count ranged from 1.9×105 CFU/mL - 5.9×105 CFU/mL. A total of nine bacterial isolates were identified which includes Staphylococcus spp, Escherichia spp, Vibrio spp, Salmonella spp, Enterobacter spp, Shiglla spp and Klebsiela spp. The result revealed a high bacterial load in the fish pond water and therefore recommends constant water change to prevent the possible buildup of potential pathogenic bacteria in fish and introduction of these organisms into the environment.
