Pump & Treat Services of Contaminated Groundwater

The Missouri Department of Natural Resources is requesting proposals for operation and maintenance services of a contaminated groundwater pump-and-treat system at the Valley Park TCE site, with proposals due September 2, 2026 at 2:00 PM Central Time through MissouriBUYS. This RFP (STATE 0000000524SL, amended August 12, 2026) carries a significant operational qualification requirement: the contractor must provide a Project Engineer and Field Engineer (both licensed professional engineers in Missouri), a Senior Scientist (licensed professional engineer or geologist in Missouri), and a Junior Scientist (licensed professional engineer or geologist in Missouri with minimum one year experience), with the team collectively demonstrating three years of experience in operation and maintenance of groundwater extraction and treatment systems.

The scope encompasses 24/7 operation of a Groundwater Extraction & Treatment System (GETS) installed in 2006 that extracts groundwater from a 12-inch well at 63.5 feet depth and treats it through anti-scaling, duplex bag filtration, and a six-tray air stripper before discharge to storm sewer. The system operates at approximately 180 gallons per minute under normal conditions. Services include project planning and management, system operation and maintenance, remote monitoring via SiteLink web-based interface, chemical handling and sampling, data management, and coordination with local, state, and federal agencies. The contractor must maintain no more than 10 percent monthly downtime and assumes all costs for materials, equipment, subcontractors, system monitoring, and special-waste disposal permits. All personnel must hold current Missouri professional engineering or geologist licenses as specified.

The contract period is one year with an option for three additional one-year renewals under the same terms. Pricing is firm and fixed, submitted by labor classification, equipment, materials, supplies, and utilities. Invoices are due monthly and paid within 30 days of valid receipt. A non-mandatory site tour is scheduled for August 20, 2026 at 1:00 PM at 555 St. Louis Ave, Valley Park. The incumbent contractor is referenced as CS202656001. Prior registration in MissouriBUYS with "Approved" status in WebProcure/Proactis and "Spend Authorized" status in MOVERS is required for award eligibility. Standard Missouri business compliance applies: tax certification, Secretary of State registration, E-Verify enrollment, and Anti-Discrimination Against Israel Act certification prior to contract award.
