Abstract:

Safe drinking water is essential to the health and well-being of the human beings. In recent years, the water is being polluted mainly due to human activities. Water pollution affects drinking water sources like ponds, lakes streams leading to shortage of clean microbial safe water for drinking purpose. In rural villages, people use pond water after filtering through a cloth for cooking and drinking purpose. They generally store it in a mud pot and in copper containers, believed to be safe for drinking purpose. The method of storage is essential in maintaining water purity and safety for drinking purposes. Based on the understanding of the literatures, we have taken efforts to study the effect of various storage vessels on the acceptable water quality where there are no bacteria especially, of faecal origin i.e. coliforms. The bore well water was collected and stored at room temperature in 10 different types of containers and evaluated for coliform bacteria at different time intervals from 0 to 25 hrs using MNP method. From the results that there was no significant reduction of coliform bacteria in the water stored in Glass. Plastic, Ceramics, Coconut shell, Aluminum and Stainless Steel container, where as significant level of reduction of coliforms bacteria was observed in the water stored in Mud pot, Brass, Copper and Silver containers suggesting that water can be stored in any one of these containers for house hold purpose free from microbes.
