As, leakage of waste from underground storage tanks and effluent from septic leach fields might reach a water source, resulting in the presence of microorganisms in the well water.
Therefore, in many cities, water from shallow wells is not used for drinking water because (B) water near the surfaces is more easily contaminated.
