👉 Spreading engineering is a specialized field focused on the design, development, and implementation of methods to control the spread of contaminants or unwanted substances in various environments, such as soil, groundwater, or air. This engineering discipline employs techniques like bioremediation, phytoremediation, and permeable reactive barriers to mitigate pollution and restore contaminated sites. By understanding the physical, chemical, and biological processes that govern contaminant movement, spreading engineers develop strategies to slow or stop their migration, thereby protecting ecosystems and human health. These methods can involve introducing microorganisms that degrade pollutants, planting vegetation that absorbs contaminants, or constructing barriers that intercept and neutralize harmful substances before they spread further.
