Polymers and Alum for Yosemite National Park

The National Park Service seeks supply and delivery of polymers and aluminum sulfate to Yosemite National Park's wastewater and potable water treatment facilities, with quotes due June 8, 2026, and questions due May 20. This is a Total Small Business set-aside, specifically designated as a Women-Owned Small Business (WOSB) 100 percent set-aside.

Place of performance includes two locations: El Portal Wastewater Treatment Plant (5083 Foresta Road, Building 750, El Portal, CA 95318) and Wawona Wastewater and Potable Water Plants in Wawona, CA. The NAICS code is 325180 (Other Basic Inorganic Chemical Manufacturing) with a 1,000-employee size standard.

The procurement is a firm-fixed-price IDIQ contract with a one-year base period (July 1, 2026 to June 30, 2027) plus four one-year option periods through June 30, 2031. The contract maximum value is $1,300,000 over the full term, with a government minimum guarantee of $10,000. El Portal requires liquid polyaluminum chloride for tertiary treatment (1,650 gallons annually), dry anionic polymer for secondary clarification (100 50-pound containers annually), liquid polymer for centrifuge digester solids, and liquid aluminum sulfate for secondary treatment (22,500 gallons annually). Wawona requires liquid PAC polymer for both wastewater and potable water treatment (5,000 and 1,200 gallons annually respectively). All products must be NSF 60/61 approved and meet specified turbidity, phosphorus, and effluent characteristics. Vendors must supply polymer samples for NPS jar testing and provide chemical makeup results and unit cost within 72 hours of testing. Pricing must be submitted as cost per 1,000 gallons treated. Evaluation criteria are price and past performance; offerors must provide at least three past performance references from similar projects within the past three years. Award will be made to a single vendor for both facility locations as a firm-fixed-price IDIQ under FAR Part 12.
