Abstract:

The issues of sewage disposal and contamination of surface waters in lakes are rapidly rising due to urbanisation, technological advances, and growing populations. Over the past few decades, the water quality of Dal Lake has experienced significant degradation, rendering it unsuitable for domestic consumption and diminishing its visual appeal. This report aims to provide an overview of the current state of water quality in Dal Lake. Water quality can be evaluated using various physio-chemical and biological indicators such as turbidity, pH, taste, odour, iron, fluoride, total dissolved solids (TDS), conductivity, nitrate, phosphorus, biochemical oxygen demand (BOD), chemical oxygen demand (COD), and coliform bacteria. Water samples were randomly sampled from several locations in Dal Lake, spanning from Dal-gate to Hazratbal. Based on the test findings and data, we observed that majority of the lake's surface is covered by weeds. This is caused by a high concentration of nitrate and phosphorus, which leads to the siltation of the lake water. Bacteriological contamination was found along the entire span of Dal Lake. The primary factor contributing to the diminished water quality of the lake is the introduction of untreated sewage, detergents, and runoff from floating gardens and houseboats. Focus group discussions were held with participants and some awareness programmes were also held to educate the people on the lakes degradation and suggestions for improving the same.
