Abstract
Physicochemical analysis of six ponds situated in different locations in the urban area of Patna, Bihar, India was investigated to evaluate the water quality of the pond. Samples were analyzed on various physicochemical parameters like Electrical Conductivity, Total Dissolved Solids, Alkalinity, Chloride, Total Hardness, orthophosphate, Dissolved oxygen and pH by using the standard methods and procedure. The observed value (average) of parameters recorded as Electrical Conductivity was 864.83 µS/cm, Total Dissolved Solids 565.83 mg/L, Alkalinity 303.33 mg/L, Chloride 70.00 mg/L, Total Hardness 260.66 mg/L, Orthophosphate 1.84 mg/L, Dissolved Oxygen 4.91 mg/L and pH 8.02. All pond’s water pH come under BIS standard. Except P6 all ponds had DO below the standards of BIS. Except P6, Orthophosphate of all samples were within standard value of the WHO. Increased level of TDS shown by (P1, P3, P4 and P6) from the standard value of BIS. Out of six samples, four had chloride value below the BIS standard. Total Hardness for P4 and P6 had value above the permissible limit of BIS standard. These six ponds are not suitable for domestic and drinking purpose, pre treatment of water is necessary. Result focused on regular monitoring of the water quality to detect contaminants.
