Patents Assigned to Earth-Tech
  • Geomorphology for environmental remediation process and systems
    Patent number: 8047743
    Abstract: The present invention includes methods for investigating a site for possible selective removal of sediment containing a contaminant. The methods include calculating an adjusted contaminant concentration for sediment zones on the site. The site preferably contains a water course. The methods may also include determining whether sediment zone need remediation by comparing the adjusted contaminant concentration to a standard. The invention also includes a system for carrying out the described methods, at least partially implemented in a computer.

  • Geomorphology environmental remediation process and systems
    Patent number: 7344337
    Abstract: According to the methods, a site is investigated for possible selective removal of sediment containing a contaminant. An adjusted contaminant concentration is calculated for sediment zones on the site. The site preferably contains a water course. A determination may be made as to whether the sediment zone needs remediation by comparing the adjusted contaminant concentration to a standard. The method may be at least partially implemented in a computer.
