What term is used for sewage leaking out of the system?

• A. Infiltration
• B. Exfiltration
• C. Displacement
• D. Contamination

Answer: (B)

The term used for sewage leaking out of the system is exfiltration. This occurs when wastewater escapes from the sewer system into the surrounding environment, often leading to pollution of soil and groundwater. This process can occur due to cracks, breaks, or poor seals in pipes, and it is a significant concern for environmental and public health, as it can introduce contaminants into places where they can harm ecosystems and human populations. Infiltration, on the other hand, refers to the unwanted water (usually groundwater) entering a sewer system, which is different from exfiltration. Displacement refers to the movement of materials or substances from one location to another and does not specifically relate to sewage systems. Contamination is a broader term that includes any introduction of harmful substances, but it does not specifically describe the process of sewage leaking out into the environment. Therefore, exfiltration is the most accurate term for this scenario.
