ABSTRACT

The present study was carried out to analyze the physicochemical parameters of 36 selected ponds in Nedumangad Block Panchayat. Water samples collected for the analysis of water quality parameters showed that the temperature varied between 25.5 and 32.5°C, 39.51 ?S to 250.67?S for EC, 4.67 to 8.58 for pH (The values observed were not within the acceptable range (6.5-8.5) of WHO for natural waters), 121.58mg/L to 2.6mg/L for DO (The lowest DO value of this pond might be due to low solubility of oxygen at high temperature (The lowest DO value of PAN-2 pond might be due to low solubility of oxygen at high temperature.), 20.11 mg/L to 127.26 mg/L for TDS, 17.34 mg/L to 543.26 mg/L for salinity, 0 mg/L - 100 mg/L for hardness, 10 mg/L - 105mg/L for alkalinity and 7.1mg/L and 24.85 mg/L for chloride respectively. All the values of total hardness found in this study were within the permissible limit for drinking standard. In the current study, the value of Na ranges from 7 mg/L to 47 mg/L. The values of potassium vary in the same manner in every pond studied. Results of physico-chemical parameters of various ponds at Nedumangad as studied in the present investigation clearly shows that the water is not good for human consumption and also struggling for their existence. Therefore, it needs some corrective measures to maintain the water chemistry of the pond.
