  • Patent number: 12678839
    Abstract: A system and method for enhanced leachate collection from a solid waste landfill site are provided. The landfill site can include, without limitation, one or more landfill waste layers, one or more leachate layers, a landfill liner layer, and a groundwater layer. A landfill gas well extends from the ground surface and passes down through the landfill waste layer and encounters a leachate layer within the waste mass. The well is configured to capture landfill gas and remove leachate from the leachate layer of the landfill site and transport it to the landfill surface. An airlift venturi pump can create venturi effect and generate discharge to deliver leachate to the landfill surface. The leachate can be piped to a gravity drain system, frac tank, collection sump or other onsite holding area, or transported to an approved offsite location for disposal.

  • Patent number: 10593004
    Abstract: In one embodiment, a method includes generating, by a computer system, a search-engine query from stored identity-theft nomenclature. The method also includes querying, by the computer system, at least one search engine via the search-engine query. Further, the method includes crawling, by the computer system, at least one computer-network resource identified via the querying. In addition, the method includes collecting, by the computer system, identity-theft information from the at least one computer-network resource. Additionally, the method includes processing, by the computer system, the identity-theft information for compromised personally-identifying information (PII).

  • Patent number: 7618547
    Abstract: This invention is directed to systems including one or more trenches or wells that include one or more perforated pipes through which a gas, such as air, can be injected into the vadose zone of ground located beyond a methaneogenic source to create a positive-pressure gas curtain and/or aerobic conditions in the vadose zone that inhibits migration of and/or facilitate the remediation of mobile volatile organic compounds that are capable of contaminating groundwater surrounding the methaneogenic source.

  • Publication number: 20070088472
    Abstract: A method is provided for validating emissions component conditions of a vehicle including the steps of operatively placing drivable wheel hubs of the vehicle under load so that the vehicle drive wheel hubs may be driven without vehicle movement and running the vehicle through an associated drive cycle associated with that vehicle. The method further includes the steps of determining if monitored emission components are in a Ready condition at the end of drive cycle, and monitoring for diagnostic trouble codes during and at the end of the drive cycle.
