<p>A sampling device (10) can monitor contaminants in groundwater. The sampling device comprises a semi-permeable membrane (14) for contact with groundwater, in which the semi-permeable membrane is permeable to contaminants and impermeable to groundwater; an inner chamber (12) formed by the semi-permeable membrane for containing the contaminants from the groundwater that diffuse through the semi-permeable membrane; and a sensor device (20) communicating with the inner chamber. The sensor device is in contact with the contaminants contained within the inner chamber for monitoring the contaminants. Sampling device can also comprise a transceiver which sends data signal (s) from the gas sensor to a data collection station via an appropriate communications link.</p> |
