Pilot-Scale Bioremediation System Design

The contract seeks the design of a pilot-scale bioremediation system that utilizes propane injection to enhance the activity of naturally occurring bacteria targeted at breaking down 1,4-dioxane in contaminated groundwater. This system is intended to be seamlessly integrated with the existing water treatment operations of the Cape Fear Public Utility Authority, ensuring compatibility and operational efficiency without major disruptions to current processes. The technical scope requires detailed engineering planning to determine optimal propane dosing rates, contact times, microbial response metrics, and monitoring protocols for effective contaminant degradation. The project is structured as a subcontract under NAICS code 541611, reflecting its focus on environmental consulting and technical design services. Proposals must be submitted by September 1, 2026, following the public posting of the solicitation on August 7, 2026. While the place of performance and point of contact details are not fully specified, the work is tied to the agency’s operations in North Carolina. The design must demonstrate feasibility, scalability, and compliance with regulatory standards for groundwater remediation, with a strong emphasis on measurable outcomes and data-driven validation of system performance under real-world conditions.
