  • City of Gallup Water
    Resources Investigations

    A regional groundwater numerical simulation model for the San Andres/Glorieta aquifer system of northwestern New Mexico has been prepared in support of the Application by the City of Gallup for Permit to Appropriate Groundwater. The numerical simulation model was mandated by the New Mexico Office of the State Engineer Hearing Examiner to support the City of Gallup’s Application. The model framework stipulated by the Hearing Examiner included the need for a three-dimensional numerical model capable of simulating aquifer stresses to the Permian San Andres/Glorieta aquifer system, the Sonsela sandstone of the Petrified Forest Member of the Triassic Chinle Formation, and leakance through the Chinle Formation.

  • Buckeye Hills and Surprise
    Shooting Range Closure Activities

    To facilitate better training of Sherriff Officers, Maricopa County closed two main County shooting ranges and re-constructed a regional training and public use shooting facility in Buckeye, Arizona. Four Corners completed the closures of the Buckeye Hills and Surprise shooting facilities for Maricopa County to allow the construction of the new facilities without long term monitoring requirements associated with most hazardous waste sites. Four Corners conducted initial investigations into lead and other contaminants in soil and developed a strategy for Maricopa to remediate and close the facilities under the Arizona Department of Environmental Quality (ADEQ) Voluntary Remediation Program (VRP).
