Study of Physico-Chemical Parameters and Pond Water Quality Assessment by using Water Quality Index at Athiyannoor Panchayath, Kerala, India
Keywords:
physico-chemical parameters, pond water, water quality, water quality Index (WQI)Abstract
This study was designed to assess the quality of pond water in Athiyannoor panchayath, Thiruvananthapuram District, Kerala, with respect to the physico-chemical parameters including Temperature, pH, EC (Electrical Conductivity), TDS (Total Dissolved Solids), TA (Total Alkalinity), DO (Dissolved oxygen), TH (Total Hardness), NaCl (Salinity), Ca (Calcium), Mg (Magnesium), Cl (Chloride), Na (Sodium) and K (Potassium). The results were evaluated and compared with WHO and BIS water quality standards. From the data obtained, the water quality index was calculated to quantify overall pond water quality status of the area. It is found that based on the WQI results the samples are falling under excellent category and hence suitable for domestic purposes.
