Which statements about wells are true? Check all that apply.

A well must extend below the water table to reach groundwater in the saturated zone, so B is true and A is false. Pumping water faster than groundwater can replenish it can cause the well to run dry, making C true. In an artesian well, pressure in the confined aquifer can force water upward and sometimes make it gush out, so E is true. Well water is not automatically unsafe to drink; its safety depends on water quality, so D is false.
