Pine and Swallow Environmental has responded to the Massachusetts DEP call for sediment sampling by adding freshwater and marine equipment to its fleet of field sampling rigs. P&S's sampling boat is ideal for sediment sampling in lakes, ponds and coastal areas. The boat has also been designed for the installation of MicroWells for sampling of ground water beneath water bodies. In addition, P&S can utilize its all-terrain field rigs on barges for more extensive work. P&S has reached sampling depths greater than 200 feet below a pond bottom.
