Environmental Restoration Technical Support Branch

Mission - To provide environmental restoration technical services for optimized restoration support for sustainable Air Force installations.

Vision - To lead the Department of Defense in technical environmental restoration innovations and solutions through people and processes by increasing effective, efficient and sustainable approaches.

Overview - The Environmental Restoration Technical Support Branch, or CZTE, provides assets, methodologies, and technical capabilities to the Technical Support Division and supports the Environmental Restoration Division, or CZR, via surveillance for performance-based remediation contracts and remediation of contaminated sites at active installations. As stewards of the environment and responsible managers of federal funds, the Technical Support Branch strives toward continuous improvement to best support the Air Force environmental restoration efforts.

CZTE provides the Air Force with a source of subject matter expertise, in the areas of environmental chemistry, hydrogeology, risk assessment, toxicology, and engineering, that is needed to evaluate new technology and industry best practices, analyze and help resolve emerging and complex restoration issues, facilitate and enhance communications and technology transfer, and keep the Environmental Restoration Program at the cutting edge of technical issues while supporting management of program risk.

The Chemistry specialty area promotes the implementation of good chemistry practices, quality systems, and project planning to enhance the acquisition of quality data for sound decision making for Air Force projects. For more information, visit the Chemistry page.


The Hydrogeology specialty area supports the enhancement of an installations' critical natural resources infrastructural knowledge, maximizes operational land use and minimizes Air Force environmental liabilities through experienced technical leadership and guidance. For more information, visit the Hydrogeology page.


The Restoration Systems and Strategies specialty area provides technical expertise to the Air Force in selection, design, implementation and optimization of restoration systems and strategies. The specialty area promotes efficient and effective restoration of contaminated sites throughout the remedy lifecycle and helps solve challenging remediation problems using sound science and engineering. For more information, visit the Restoration Systems and Strategies page.

Technical Surveillance

The Environmental Restoration Technical Support Branch provides technical expertise in surveillance for Air Force Environmental Directorate performance-based remediation contracts. The branch focuses scientific and engineering expertise on contaminated sites with high complexity, cost and risk, while providing technical guidance across the Air Force for remediation strategies, program planning, and contract solicitation and execution. For more information, visit the Technical Surveillance page.


The purpose of the Emerging Issues/ Contaminants  is to assist the Environmental Directorate in identifying and determining the impact of new emerging environmental issues or contaminants and assessing the impact of these contaminants and issues on environmental restoration activities. For more information, visit the Emerging Issues/Contaminants page.

Technology Transfer

The Technology Transfer, or T2, program promotes the efficient transfer of environmental information to the widest audiences possible.

The T2 process consists of three steps:

  • Step 1: Assess needs identified via restoration program efforts including technical surveillance findings.
  • Step 2: Demonstrate and validate technologies via Broad Agency Announcements, or BAAs, and partnerships.
  • Step 3: Communicate scientific knowledge to assist environmental programs.

The Air Force Civil Engineer Center Environmental Remediation BAA seeks to fund better, faster and more sustainable environmental solutions for the Air Force. For more information, visit the Technology Transfer page.
