Two sampling techniques have been developed which enable ground water samples to be obtained from various depths within shallow aquifers and littoral sediments. Both techniques involve the insertion of a percussion-driven spike to the desired depth. One method employs a sampling probe consisting of a perforated tip and a mechanism for the prevention of blockage by grit during the driving process, with samples being withdrawn through an internal plastic tube. The other technique involves permanent installation of a perforated plastic capsule connected to the surface by plastic tubing. Some examples of chemical data obtained during extensive testing of these techniques are presented. It is concluded that the techniques could have considerable application in the investigation of shallow ground water and littoral sediment chemistry.Please view the pdf by using the Full Text (PDF) link under 'View' to the left.
