The National Park Service Midwest Region is seeking contractors to replace granulated activated carbon (GAC) filter media at Rocky Mountain National Park's Headquarters East water treatment plant. This firm fixed price purchase order (solicitation 140P6325Q0022) requires contractors to furnish all labor, materials, and equipment necessary to remove and dispose of spent activated carbon and refill filter vessels with fresh Calgon Carbon Filtrasorb 400 granular activated carbon or an approved equivalent. The GAC material must meet AWWA B604 standards and NSF/ANSI Standard 61 for potable water filtration, specifically designed to remove dissolved organics and compounds that cause taste, odor, and trihalomethane issues. Interested contractors must have a Unique Entity Identifier (UEI) number and be registered in the System for Award Management. The full solicitation package is expected to be posted on SAM.Gov within 5 business days, with responses due around August 22, 2025.

This opportunity is set aside 100% for small businesses under NAICS code 221310 (Water Supply and Irrigation Systems) with a size standard of $41.0 million. The performance period runs from October 1, 2025 through September 30, 2026, providing contractors with a one-year timeframe to complete the filter media replacement services. No incumbent contractor or current service provider is identified in the pre-solicitation documentation. The contract structure as a firm fixed price purchase order suggests the government has established parameters for the scope of work and expects competitive pricing from qualified small business contractors. The specific focus on Calgon Carbon Filtrasorb 400 or approved equivalent indicates technical specifications that will require contractors to demonstrate familiarity with specialized water treatment materials and processes.
