About the company
Commercial Testing Laboratory Inc., a veteran-owned Subchapter S corporation based in Colfax, Wisconsin, operates as a prime contractor providing water testing and laboratory analysis services to the federal government under no set-aside designation, competing full and open. The vendor holds a single-customer relationship with the Department of the Interior National Park Service Midwest Region, for which it has executed 126 of 131 awards (96% of its prime footprint) with combined potential value of $87 thousand, spanning water quality monitoring at the St. Croix National Scenic Riverway and related Midwest region parks and facilities.
Commercial Testing Laboratory Inc. performs laboratory analysis of water samples under small business full-and-open solicitations. Work is classified under NAICS 541380 (Testing Laboratories and Services) and PSC environmental systems protection, with 124 of 129 awards tagged to water quality support. The vendor's recent representative awards include monthly BPA calls issued by the National Park Service Midwest Region — $462 in May 2026, $517 in July 2025, $345 in September 2025, and $330 in August 2025 — all firm fixed price. The underlying parent vehicle is a single-award Blanket Purchase Agreement (140P6024A0002) established June 1, 2024, with a $20 thousand ceiling and completion date of May 31, 2029. The vendor also holds two legacy BPAs: 140P6019A0001 (59 task orders, $12 thousand combined potential value) and INP16PA00011 (35 task orders, $7 thousand combined potential value), which together account for most of the vendor's award volume since 2021.
Activity has been consistent year over year, averaging roughly 11–13 awards per calendar year from 2022 through 2025, with 8 awards recorded in 2026 through August. The vendor's federal footprint is entirely prime work, with zero subcontract engagement. All work is performed at the contractor's facility in St. Croix Falls and Trego, Wisconsin. The vendor is required to maintain Wisconsin Department of Agriculture, Trade and Consumer Protection laboratory certification and deliver analytical reports within ten business days of sample receipt. The vendor operates exclusively under the National Park Service Midwest Region, creating customer and vehicle concentration risk; five recompete opportunities totaling $7 thousand in combined potential value are due to complete in the next twenty-four months across the legacy BPAs.
