Tetrasolv Filtration buyer-window signal capture

Evidence

• Delaware's official bid listing opened July 14, 2026 and sets September 15, 2026 at 1:00 PM local time as the proposal deadline.
• Delaware's Q&A says the large mobile unit treats up to 350 GPM and uses granular activated carbon; the smaller 30 GPM unit uses Fluoro-sorb 200.
• Delaware's Q&A resolves conflicting RFP wording and states that subcontractors will be permitted.

Practical opening

“Delaware is accepting proposals until September 15 for operating its mobile PFAS treatment systems. The larger state unit treats up to 350 GPM with granular activated carbon. The live bid directly matches Tetrasolv's mobile GAC and media-service pattern. We could enter through the prime bid or a certified operating partner.”

Claim boundaryDo not claim Tetrasolv is qualified to bid as prime or that Delaware will accept it; licensing, staffing, and proposal compliance remain unverified.

Tetrasolv's public cases do not prove full municipal system operation, sampling, laboratory coordination, or Delaware operator certification.

Evidence

• SGWASA reported on August 10, 2026 that the Advanced Water Treatment facility reached 60% design in June, with 90% due in September and final design expected in December 2026.
• North Carolina's project record specifies pressure contact vessels, GAC or ion-exchange contactors and media, pumping, yard piping, electrical instrumentation, and controls.
• North Carolina announced a $21,868,000 loan for SGWASA's Post-Filter PFAS Treatment Improvements Project on July 16, 2026.

Practical opening

“SGWASA reached 60% design in June, with 90% due in September and final design in December. Its scope names pressure vessels, GAC or ion-exchange contactors, media, pumping, piping, and controls. The design phase directly exposes Tetrasolv's vessel and media lane. We could offer a GAC vessel and media review before the next design package closes.”

Claim boundaryDo not claim GAC is selected, the equipment package is open, or Tetrasolv has a proven municipal ion-exchange installation.

AquaPRS supplies the current pilot and CDM Smith controls the permanent specification; the final GAC versus ion-exchange choice is not public.

Evidence

• EPA approved BASF's 100% Basis of Design on June 29, 2026, finalizing the groundwater remedy and authorizing construction to begin in early 2027.
• The 95% Basis of Design specifies 48 GPM average and 150 GPM peak flow, GAC followed by ion exchange, Calgon DSR-C carbon, and Purolite PFA694 resin.
• BASF says North Works has more than 1,000 employees, five manufacturing plants, and more than $50 million in annual contractor and service spending.

Practical opening

“EPA approved BASF's final groundwater-cleanup design on June 29 and authorized construction for early 2027. The pre-final design uses GAC then ion exchange at 48 GPM average and 150 GPM peak, naming Calgon carbon and Purolite resin. That suggests contractor and equipment choices are active, but the named media may already be fixed. We could test vessel fabrication, approved-equivalent supply, or later media service.”

Claim boundaryDo not claim BASF is seeking a new vendor, that the named media can be replaced, or that the final design retained every pre-final specification.

Arcadis controls the design, and the pre-final document names Calgon carbon and Purolite resin; an approved-equivalent route is not public.
