Which feature is essential for reducing groundwater contamination at a modern sanitary landfill?
Correct answer: A. An impermeable liner with leachate collection
- A. An impermeable liner with leachate collection
- B. Open dumping without compaction
- C. Direct discharge of rainfall into nearby drains
- D. Burning all waste inside the landfill cell
Explanation
A liner limits downward movement of contaminated liquid, while leachate collection allows that liquid to be removed and treated. Open dumping and uncontrolled drainage increase the risk of soil and groundwater pollution.

About Environmental Engineering
Environmental engineering examines water supply, water quality, treatment processes, wastewater collection and treatment, solid waste management, air pollution and public health protection. It covers sedimentation, coagulation, filtration, disinfection, biological treatment and disposal methods, while distinguishing drinking-water treatment from sewage treatment and BOD from COD.
