G ___ would help prevent the creation of leachate. would help prevent the creation of leachate. Adding water to solid waste prior to landfilling Capping the landfill when it is filled to capacity Adding oxygen to solid waste prior to landfilling Adding hazardous chemicals to solid waste prior to landfilling Using a single-liner system rather than a double-liner system

Geotextile would help prevent the creation of leachate.  Using a single-liner system rather than a double-liner system would help prevent the creation of leachate.

Explanation:

Landfill liners must have several layers, including a one of soil, then a geotextile (a synthetic permeable membrane) layer that lets water through but filters out any small pieces of trash, a leachate (water) collection system, a plastic liner layer in order to prevent leachate from reaching the groundwater, and to prevent leachate from polluting the underlining groundwater.  

The generation of leachate is caused principally by precipitation percolating through waste deposited in a landfill. Once in contact with decomposing solid waste, the percolating water becomes contaminated, and if it then flows out of the waste material it is termed leachate.

Therefore, there are many methods of leachate treatment such as: Aerobic Biological Treatment such as aerated lagoons and activated sludge. Anaerobic Biological Treatment such as anaerobic lagoons, reactors. Physiochemical treatement such as air stripping, pH adjustment, chemical precipitation, oxidation, and reduction.
