Interceptor Wells
  At the Questa mine, Ground-Water Diversion (Interceptor) Wells have been installed to intercept and collect ground water prior to its infiltration into reclaimed backfill and other areas. These wells are drilled up gradient of the backfill area and can be oriented vertically or horizontally. Care should be taken not to over pump these wells, which can cause a reversal of groundwater flow. If the water table is lowered to the point that groundwater is drawn from the reclaimed operation, the water may require treatment prior to discharging. The intent of diversion wells is to prevent water movement into the strip, not to create a pump-and-treat operation.
