Comparative Study of Chemical, Physical and Biological Analysis of Some Pond Water Ecosystems in Valsad of the State Gujarat, India.

We all know that water is our most important life survival factor, but due to urbanization our surface water bodies are being polluted day by day. In order to maintain the water quality of any surface water body it requires accessing the physiochemical and biochemical aspects of water periodically. This investigation is one of the most overlooked aspects of pond management system too. Present study highlights the preliminary investigation of physiochemical characteristics of four pond ecosystems viz. Halar Talav, Nanakwada Talav, Rakhodiya Talav and Segvi Talav. From each pond randomly 11 samples were collected and mixed to make four better representative samples. These samples have been assessed on the basis of various qualitative parameters like pH, temperature, turbidity, electrical conductivity (EC), total dissolved solids (TDS), total suspended solids (TSS), total hardness (TH), Total Alkalinity (TA), Chloride (Cl), dissolved oxygen (DO), chemical oxygen demand (COD), biological oxygen demand (BOD). The results obtained from the present work indicate that there are some diverse contaminations and pollution in these ecosystems. Therefore it is unsafe to use directly for human uses and hence needs more attention for its sustainability factor
