What is a leach field?

• A. A system for storing sewage
• B. A component that disperses treated wastewater
• C. An area where solid waste is buried
• D. A treatment facility for hazardous waste

Answer: (B)

A leach field is an essential component of a septic system designed to disperse treated wastewater into the soil. After wastewater flows from the septic tank, it typically undergoes a process of settling and separation, where solids settle at the bottom, and the liquid effluent is discharged. The leach field consists of a series of trenches or beds filled with gravel or rock, which provide a structure through which the treated wastewater can seep into the soil. This process is vital because the soil acts as a natural filter, further treating the wastewater by allowing microorganisms to break down any residual contaminants. The design of a leach field aims to prevent sewage from pooling on the surface and ensures the safe return of purified water to the groundwater, thus protecting the surrounding environment and public health. The characteristics of the soil and the proper design of the leach field are crucial to its effectiveness in treating and handling wastewater.
