The SDS Pump is a deep well sampling system which allows sampling without purging. A bailer is lowered down the well to the desired depth. As soon as the bailer reaches the water, it fills up. When the bailer reaches the depth of the desired sample, a pump inside the bailer is powered, replacing the stagnant well water with water from the screened intervals of the well.
