Lake ecosystems are an integral part of the Bangalore city. Lakes in Bangalore were mainly created to serve the need for drinking and agriculture. But unplanned urbanisation and industrialisation has lead to the contamination of these water bodies. Varthur lake, situated in south Bangalore has a water-spread area of 2.5 sq. km. The lake water is mainly used for agriculture and supports a wide diversity of flora and fauna. The inflow of sewage and agricultural runoff in addition to the inflow of contaminated water from Bellandur lake has led to the rapid deterioration of the lake. As the contaminated lake water is used for irrigation purposes, it is essential to assess the soil quality in and around lake. Various physico-chemical soil parameters were analysed using standard methods and the results are discussed in the paper.
