  • Conceptual design

  • Environmental construction, implementation, demolition, and repair of various IRP, MMRP, and compliance sites

  • O&M of installed groundwater systems

Additional work includes:

  • Bench-scale and pilot-scale treatability studies

  • Remedial actions

  • Removal actions

  • Tank removals

  • Excavations

  • LNAPL/DNAPL abatement/recovery

  • In-situ groundwater remediation

  • Long-term monitoring

  • Groundwater modeling

  • Natural attenuation studies

 

LATA supports the Air Force with community involvement at two installations by facilitating Restoration Advisor Board (RAB) meetings, preparing informational packets to RAB members, and providing meeting minutes to the Administrative Record. The work is being performed under CERCLA, with regulatory oversight provided by Texas Commission on Environmental Quality and EPA Region 6.
