Abstract

A pond is a natural or artificial, seasonal or perennial lentic water body. The ponds need periodic assessment for conservation and rejuvenation. Phulwarisharif is a block town of Patna, Bihar, India and includes the Patna Metropolitan region. An attempt was made to compare the present water quality of perennial Manikchand Pond and Phulwarisharif Pond, Phulwarisharif area, Patna using the Comprehensive pollution index (CPI), Overall pollution index (OPI) and Water quality index (WQI) during September 2022-August 2023 from 240 water samples and 10 sampling sites. To assess water quality, thirteen water quality parameters were measured using standard techniques during the post-monsoon, winter, summer, and monsoon seasons. Results indicated that the water quality had deteriorated and that the parameters exceeded BIS (2012) recommended limits are pH, dissolved oxygen, biochemical oxygen demand, total alkalinity, total dissolved solids, turbidity, nitrate and sulfate. The water quality parameters differ significantly (p<0.05), according to two-way ANOVA. The values of OPI (2.30 to 2.60) and CPI (1.60 to 1.70) without turbidity and with turbidity (2.40 to 2.70) and CPI (3.60 to 4.40) respectively indicate slightly polluted/polluted and slightly polluted/seriously polluted water in Phulwarisharif pond. But the values of OPI (1.54 to 1.88) and CPI (1.34 to 1.36) without turbidity and with turbidity (1.77 to 2.17) and CPI (3.07 to 3.93) respectively suggest acceptable/polluted and acceptable to slightly polluted/seriously polluted water in Manikchand pond. These indices confer that Phulwarisharif Pond is more polluted than Manikchand Pond. The present observation demonstrates that anthropogenic activity and the entry of untreated sewage are the main contributors to the decline in water quality. The water quality of these ponds felt the need to adopt proper management policies and conservation efforts to decrease the time-consuming and expensive water quality monitoring and assessment programmes.
