Assessment of Water Quality with Special Reference to Hydrochemistry: A Case Study of Auranga Estuary, Valsad, Gujarat, India
An assessment of Water Quality from Auranga estuary (20°63’ N and 72°820 E) was carried out from January 2019 to December 2019. The hydro-chemical variables were analyzed for the evaluation of water quality showed fluctuation in the estuarine water seasonally. The water quality index was computed for the evaluation of water quality of Auranga estuary; to know the pollution level of water body Index for Pollution was also computed. The water quality index (WQI) was 115.97 at downstream and 85.30 at upstream that indicate poor and good water quality respectively. The Pollution Index (PI) ranges from 1.41 (Downstream) to 0.78 (Upstream) which indicate that the water is medium polluted and slightly polluted respectively. Seasonal assessment showed the discrete water quality index and pollution index based on three different seasons; during winter season WQI was 143.30 and 108.05 and PI was 1.41 and 0.97 at downstream and upstream respectively, during summer WQI was 126.73 and 106.95 and PI was 1.18 and 0.94 at downstream and upstream sites respectively and during monsoon WQI was 97.67 and 88.11 and PI was 0.88 and 0.78 at downstream and upstream sites respectively. Univariate statistical technique is attempted to explain the correlations between the variables.
