STATEMENT OF OBJECTIVES

Bench Scale Feasibility Study: GAC RENEW Eielson AFB, AK

Prepared By: MSgt Andrew Dietzold, 354 Civil Engineer Squadron Table of Contents

1. Purpose The Government seeks contractor support to evaluate the technical feasibility of a granular activated carbon (GAC) renewal process for spent PFAS treatment media currently used at Eielson AFB’s Water Treatment Plant.

The objective is to determine whether the proposed renewal process can effectively regenerate spent GAC under operating conditions relevant to Interior Alaska and support a future Government decision regarding pilot-scale demonstration or field deployment.

This requirement is for professional scientific, engineering, analytical, and advisory services only and does not include procurement of treatment systems, construction, or operational services.

2. Background Eielson AFB utilizes GAC-based treatment systems primarily for PFAS removal from drinking water sources. Current media management practices require periodic replacement and shipment of spent carbon off-site and out of state.

The Government is interested in evaluating whether an alternate GAC renewal technology may provide a technically viable option for future use, particularly considering:

· Logistical constraints, including Eielson’s remote and isolated designation

· Cold weather operating conditions

· Existing GAC system vessel compatibility

· Continued PFAS treatment effectiveness

3. Objectives The Contractor shall develop and execute a bench-scale feasibility approach that addresses the following objectives:

3.1 Technical Feasibility

Determine whether spent Eielson AFB GAC can be successfully renewed using the proposed process.

3.2 Cold Weather Applicability

Evaluate process performance at representative low-temperature conditions (minimum target: approximately 35°F liquid operating condition).

3.3 PFAS Treatment Performance

Assess post-renewal media effectiveness for PFAS removal using recognized analytical methods.

3.4 Process Practicality

Evaluate rinse efficiency, solvent removal practicality, and suitability for field implementation.

3.5 Deployment Path Forward

Provide options and recommendations for potential pilot-scale demonstration or future deployment.

4. Scope The Government expects offerors to propose a technical approach that may include:

· Review of Government-furnished water quality and operational data

· Receipt and handling of spent and unused GAC samples

· Bench-scale renewal testing

· PFAS analytical testing

· Screening-level feasibility conclusions

· Conceptual pilot deployment options Offerors are encouraged to propose innovative, efficient approaches consistent with commercial best practices.

5. Deliverables At minimum, the Contractor shall provide:

5.1 Technical Memorandum

A concise written report that summarizes the following:

· Methods

· Test conditions

· Results

· Key findings

· Feasibility determination

· Recommended next steps

5.2 Stakeholder Meetings

One virtual briefing / conference call to present results and answer Government questions.

6. Period of Performance The anticipated period of performance is approximately:

· 30 calendar days after receipt of Government-furnished samples

7. Government-Furnished Information The Government anticipates providing:

· Spent GAC sample(s)

· Unused GAC sample(s)

· Available water quality data

· General operating information relevant to treatment systems

8. OASIS+ Scope Compliance Statement This requirement is limited to professional engineering, scientific, analytical, logistics-planning, and advisory support services. It does not require construction, manufacturing, system operation, or supply acquisition as the principal purpose, and is intended to be performed consistent with OASIS+ scope.

9. Proposal Expectations Offerors should submit concise proposals describing:

· Technical approach

· Relevant experience

· Schedule

· Key personnel

· Assumptions
