The Earth comprises three interrelated spheres: the Atmosphere, Hydrosphere, and Lithosphere. The Atmosphere, primarily nitrogen and oxygen, shields against harmful solar radiation. The Hydrosphere includes water bodies covering over two-thirds of the Earth’s surface. The Lithosphere consists of soil, a crucial carbon reservoir supporting plant and microbial life. The Green Revolution has boosted food production through irrigation, improved seeds, fertilizers, and pesticides, but excessive chemical pesticide use has led to environmental pollution, affecting soil and water. Pesticides contaminate water through runoff, causing bioaccumulation and biomagnification, which disrupt aquatic ecosystems. Microbial bioremediation offers a sustainable solution, with bacteria degrading chemical residues and restoring balance. This study assesses the physicochemical characteristics of water and soil samples from Southern Tamil Nadu, India, isolates beneficial microbes, and evaluates their bioremediation and mosquito control potential. The findings will aid in environmental restoration and promote eco-friendly microbial pesticides, using statistical modeling and GIS techniques to understand water bodies’ ecological health.
