Abstract: A groundwater decontamination system includes a decontamination unit adapted to be lowered down through a non-pumping well into an aquifer containing contaminated water. The unit can also be raised up and out of the non-pumping well for cleaning, servicing or replacement. The decontamination unit includes a porous outer tube with a plurality of holes through which contaminated water flows, and a porous inner tube with a plurality of holes through which flows in-flowing contaminated water flowing through outer tube. A contaminant removing reactive barrier material is disposed within the inner tube for removing on contact contaminants from the in flowing water. A flow directing arrangement, preferably in the form of flow directing fins, directs in-flowing water from the holes in the outer tube to the holes in the inner tube (i.e., provider of the channeling of the ground water into the reactive barrier material). The system can monitor the contaminant removal, as well as other conditions of the groundwater.

Abstract: A permeable barrier for decontaminating groundwater having two distinct components for increasing contaminant removal. Preferably, the barrier material is a mixture or distinct layers of bone-char phosphate material and iron oxide pellets. The barrier material can be incorporated as part of a shallow trenching decontamination system, or incorporated in a non-pumping well, or array of non-pumping wells, as part of a deep underground decontamination system. The system can be used for removing, among other things, a radionuclide, such as uranium, from water.

Abstract: A network connection blocker for monitoring connections between host computers in a network and blocking the unwanted connections. The host computers transmit connection packets between each other in accordance with a network protocol suite when seeking to establish, providing network services with, and close the connections. The network protocol suite includes a connection oriented transport layer protocol. The network connection blocker comprises a network interface that receives the connection packets transmitted between the host computers. It also comprises a blocking module that processes the received connection packets to detect the unwanted connections. The blocking module then generates connection packets in accordance with the network protocol suite to cause the detected unwanted connections to be closed by the corresponding host computers between which are the unwanted connections. The network interface then transmits the generated connection packets to these host computers.
