Hi, Your well is very shallow and susceptible to potential sources of pollution. First, you could get your water analyzed by a laboratory to see how is the water quality. Depending on the water quality, you may find appropriate residential water treatment systems for the water quality and to protect you against any potential contamination.
In theory ANY water can be rendered potable. It all boils down to what contaminants need removing, and how much you want to spend.
