Seasonal Variations in Physicochemical Characteristics of Ram Mandir Pond, Vasai, Dist. - Palghar, Maharashtra (INDIA)

Abstract: Ponds remain importantresources of water from ancient time. Vasai - Virar city is suburban part of Mumbai city comes under district Palghar. In the city there are more than 100 pounds on record. Of these ponds ‘Ram Mandir Pond’ situated in the heart of city.20 physicochemical parameters selected for studying pond water were Temperature, pH, Conductivity, Turbidity, Total solids, DS, TSS Dissolved Oxygen, Acidity, Alkalinity, BOD, COD, Nitrate, Nitrite, Total Phosphorus, Silica as SiO2, Sulphate, H2S, Chlorides as Cl, and Total hardness as CaCO3 Physicochemical study of this pond reveals seasonal variation of pH of water ranging from 6.65 to the higher as 8.93. Seasonal variation in Total hardness ranging from 470 to 860 mg/l of carbonates. Nitrate values in water found highest during winter i.e. 1.11mg/l and lowest during Monsoon i.e. 0.377 mg/. Total phosphorus recorded in three seasons was 0.27, 0.16 and 0.12 mg/l in monsoon winter and summer respectively. Most of the parameters are in and around standard values. Physicochemical studies indicate pond is of mesotrophic category. Remedies for its conservation and maintenance are suggested.
