Assessment of Physico-Chemical Parameters in Mantrala Lake, Hyderabad

Abstract

The present paper deals mainly with the study of physico-chemical parameters assessment in Mantrala lake, Hyderabad. Physico-chemical parameters of water are a prime consideration to assess the water quality of a lake for its best utilization. Surface water samples were collected from the lake every month during December, 2013 to November 2014. The physico-chemical parameters studied included pH, chlorides, nitrates, phosphates, total solids, total dissolved solids, total hardness, magnesium, carbonates, bicarbonates, dissolved oxygen and organic matter from 3 different stations. Physico-chemical parameters of the water samples such as pH (8.2 - 8.92), chlorides (344.46 – 396.66 mg/L), nitrates (8.55 – 14.6 mg/L), phosphates (6.22 – 11.2 mg/L) , total solids (840 - 990 mg/L), total dissolved solids (550 - 680 mg/L), total hardness (410.26 – 526.58 mg/L), magnesium (70.42 – 98.24 mg/L), carbonates, (32.18 – 54.58 mg/L), bicarbonates ( 222.24- 298.56 mg/L), dissolved oxygen (1.2 – 3.2 mg/L) and organic matter (5.4 - 9.2 mg/L) were recorded in the present investigation. The values obtained in the present study were not acceptable according to drinking water quality standards (WHO, 1990).
