Analytical study and microorganisms present in rain water of different areas

Rainwater serves as a source of many essential nutrients in terrestrial and aquatic ecosystems. Rainwater harvesting is the process of storing water in sub surface so that it can be used later. The pollution increases day by day due to industrialization, population exploitation, deforestation and vehicular exhaust. Due to the change in environmental conditions the purity of the rain water is gradually decreasing and furthers this effect the growth of various organisms and plants in various ecosystems. In this study the rainwater samples were collected from four different environmental conditions such as forest area, rural area with less and high pollution and industrial area. The quality of this work mainly is on analysis of microbial growth, biological oxygen demand, chemical oxygen demand, temperature, pH, chlorides, carbonates, bicarbonates, sulphates, turbidity and hardness of rain water. This project can be further extended in order to purify the rain water by special instruments so that life of species can be balanced. The project can be approached from different studies such as environmental science, chemistry and microbiology.
