  • Publication number: 20040067107
    Abstract: A system, computer program product and method of preventing and controlling sulfide mineral oxidation and generation of acid rock drainage in a mass of sulfidic waste is provided. The mass of sulfidic waste includes a cover. The method involves applying under the cover of an oxygen deficient/non-reactive gas mixture, substantially throughout the mass of sulfidic waste, in a quantity sufficient to create a pressure differential between the inside of the mass of sulfidic waste and the open atmosphere outside and adjacent to the mass of sulfidic waste, such that the oxygen gas concentration inside the mass of sulfidic waste is substantially equal to, or less than, the atmospheric oxygen gas concentration outside and adjacent to the mass of sulfidic waste. The system includes a distribution system and sensors for detecting acid rock drainage conditions of the mass of sulfidic waste, and in response applying an effective amount of oxygen deficient/non-reactive gas mixture.

  • Patent number: 6688811
    Abstract: A method for reducing the leaching of lead from a lead projectile impact area acting to collect or stop such projectiles includes contacting the lead projectile impact area with a seed of dry granular lead stabilizing agents. This seeding or coating of lead stabilizing agents stabilizes lead in the bullet/shot impact area while also allowing for future lead bullets, fragments or lead shot fired into the soil to be stabilized upon contact with the lead stabilizing agent seeds or contact with rainwater leaching through the lead stabilizing agent seeds produced from the projectile coating, or excess seed from the lead shell projectiles. This method eliminates the need to remove or re-treat range soils and greatly reduces the environmental and health risks associated with the use of lead as projectiles in the open environment as well as at control trap ranges.

  • Publication number: 20030190194
    Abstract: An advanced containment system for containing buried waste and associated leachate. A trench is dug on either side of the zone of interest containing the buried waste so as to accommodate a micro tunnel boring machine. A series of small diameter tunnels are serially excavated underneath the buried waste. The tunnels are excavated by the micro tunnel boring machine at a consistent depth and are substantially parallel to each other. As tunneling progresses, steel casing sections are connected end to end in the excavated portion of the tunnel so that a steel tube is formed. Each casing section has complementary interlocking structure running its length that interlocks with complementary interlocking structure on the adjacent casing section. Thus, once the first tube is emplaced, placement of subsequent tubes is facilitated by the complementary interlocking structure on the adjacent, previously placed, casing sections.
