Abstract
A sampling device can monitor contaminants in groundwater. The sampling device comprises a semi-permeable membrane for contact with groundwater, in which the semi-permeable membrane is permeable to contaminants and impermeable to groundwater; an inner chamber formed by the semi-permeable membrane for containing the contaminants from the groundwater that diffuse through the semi-permeable membrane; and a sensor device communicating with the inner chamber. The sensor device is in contact with the contaminants contained within the inner chamber for monitoring the contaminants.
