Lake contamination is most likely caused by agricultural runoff containing pesticides and fertilizers, industrial discharges, untreated sewage, and stormwater runoff. These pollutants introduce harmful substances like heavy metals, pathogens, and nutrients, which can cause eutrophication, harm aquatic ecosystems, and endanger human health. Litter and plastic waste add to the contamination.
