We offer a variety of bailers for groundwater and well water sampling. Bailers are often used to sample monitoring wells for contaminants and to monitor the conditions of groundwater (at the water table) by geologists,environmentalists, and surveyors. Bailers are typically lowered into a water source with twine or string where the bailer is filled with water. When the bailer is pulled up, water stays in the bailer and the water is then transferred to a sampling vial for later testing. Our bailers are weighted and clear for ease of use.
