The best choice to line the bottom of waste dumps in order to protect aquifers from pollution is clay. Clay has a high absorptive capacity and low permeability which makes it an effective barrier against the migration of pollutants. It can also help in preventing the leaching of harmful chemicals into the aquifers. Other choices like gravel, sand, and soil may not provide sufficient protection against pollution, and compost may not be a suitable option for lining the bottom of waste dumps.
