BASIC STUDIES ON RECLAMATION OF BELLANDUR LAKE

Environmental Engineering

Lakes and bodies of water, also known as wetlands, are among the most productive ecosystems that contribute to ecological sustainability, thus providing the necessary links between land and water resources. The quality and hydrology of these lakes and wetlands depend directly on the integrity of the basin. In recent decades, rapid urbanization coupled with unplanned human activities has dramatically altered wetland ecosystems globally. Changes in land use and land cover (LULC) in wetland watersheds affect water production and water quality in lakes. In addition to the LULC changes, the influx of untreated domestic wastewater, industrial wastewater, solid waste dumping and rampant basin encroachment have threatened the livelihoods of urban wetlands. This is evident from the nutrient enrichment and consequent proliferation of macrophages, which degrade the functional capacities of wetlands. The reduced treatment capacity of wetlands has resulted in loss of native biodiversity, widespread unsanitary conditions with the threat of mosquitoes, pollution of groundwater levels, impacts on biodiversity and environmental degradation of people who depend on wetlands. The decline of services and goods by wetland ecosystems has affected social, cultural and ecological spaces as well as water management. This paper observes the negative and harmful effects of lake water pollution on the environment and the surrounding community as well as the quality of water after its treatment. The most common form of water pollution has been waste disposal via human activities. The study conducts tests on water samples from the Bellandur Lake. Recorded values of pH, turbidity, hardness, lead (Pb), Cadmium (Cd), chloride (Cl), total phosphate (Po4-2),total acidity, total alkalinity, the temperature measured during the time of sampling varied from 26 – 28 °C and presence of heavy metals such as lead and cadmium for before and after the water treatment have thus compared to analyze the extent of water hygiene delivered.
