Water Quality Assessment and Biodiversity Study of Phytoplanktons in Angol Water Body of Belagavi (Karnataka)

Abstract

Abstract
Physico-chemical testing of angol water body revealed that the calcium hardness ranges from 65 mg/L to 110 mg/L, dissolved oxygen 2.8 to 9.8 mg/L, temperature 21 C to 25 C , pH 6.8 to 9.8, iron 0.1 mg/L to 1.0 mg/L, turbidity 0.381m to 0.6096 m, nitrite 0.0 mg/L to 0.3 mg/L, nitrate 18 mg/L to 23 mg/L, chloride 70 mg/L to 190 mg/L, total hardness 100 mg/L to 220 mg/L ,residual chlorine 0.0 mg/L to 0.2 mg/L ,ammonium 0.0mg/L to o.1 mg/L, phosphate 0.0 mg/L to 0.5 mg/L, fluoride 0.0 mg/L, electrical conductivity ranges from 430 μS/cm to 540 μS/cm and total alkalinity 65 mg/L to110 mg/L. Biodiversity of phytoplankton in angol water body revealed a total of 24 species belonging to five classes in which Bacillariophyceae-11 species, Chlorophyceae-10 species, Cyanophyceae-1 species, Dinophyceae-1 species and 1 species of Euglenophyceae. Bacillariophyceae species were abundant. Algal pollution index revealed a score of 22 indicating that angol water body is organically polluted. Based on the test conducted we concluded that angol water body is less polluted by organic waste and is unfit for drinking but can be utilized for re-creational activities, domestic usage, agriculture and fish rearing.
