👉 Barrier engineering involves the design, construction, and implementation of physical or technological barriers to prevent the spread of contaminants, pollutants, or unwanted materials. These barriers can be natural, such as geological formations that filter water, or engineered, like advanced filtration systems, permeable reactive barriers, or engineered wetlands. The primary goal is to mitigate environmental risks by controlling the movement of hazardous substances from sources to sensitive areas, thereby protecting ecosystems and human health. Barrier engineering integrates principles from civil, environmental, and chemical engineering to create effective solutions tailored to specific environmental challenges.
