CT Laboratories, LLC

CT Laboratories, LLC, a Women-Owned Small Business (WOSB) certified environmental testing laboratory based in Baraboo, Wisconsin, operates as a prime contractor (89% of recent awards) providing soil, sediment, water, and air sample analysis to federal agencies, primarily the Army Corps of Engineers across multiple districts. The company competes predominantly under full-and-open procurement with recurring set-asides for total small business concerns and woman-owned small businesses; since its SAM.gov registration in 2003, it has established itself as an established provider of environmental analytical chemistry services supporting federal environmental compliance, remediation, and monitoring missions across Midwestern military installations, civil works projects, and civilian agency facilities.

CT Laboratories' customer concentration is heavily tilted toward Army Corps of Engineers district operations. The top five customers by award count account for 78% of recent awards, with Louisville District anchoring the portfolio at 122 awards ($7.1 million combined potential value), followed by Omaha District (42 awards, $2.4 million), Kansas City District (25 awards, $10.7 million), a generic Army Corps of Engineers entity (19 awards, $408 thousand), and Baltimore District (19 awards, $6 million). The potential-value ranking surfaces Kansas City District as the largest dollar driver at $10.7 million across 25 awards—a different lead customer than by volume—while Louisville District's 122 awards carry lower per-order value, reflecting the company's reliance on task-order-based work under Corps IDIQs and BPAs rather than large multi-million-dollar single awards.

CT Laboratories holds a substantial portfolio of parent contract vehicles with the Army Corps. The company places task orders under five core IDIQs and BPAs: Indefinite Delivery Contract W912QR10D0024 (58 task orders, $1.3 million combined potential value), Indefinite Delivery Contract W912QR07D0019 (37 task orders, $492 thousand), Blanket Purchase Agreement W9128F11A0001 (24 task orders, $168 thousand), Indefinite Delivery Contract W912DQ09A1001 (21 task orders, $363 thousand), and Indefinite Delivery Contract W912QR16D0019 (21 task orders, $263 thousand). More recently, CT Laboratories secured a $1.5 million multiple-award BPA with Defense Counterintelligence and Security Agency Kansas City (awarded August 2025, running through August 2030), a $450,000 multiple-award BPA with Army Corps Omaha District (December 2024 through December 2029), and holds a $1.25 million BPA with Army Corps Baltimore District (through May 2028). These vehicles represent the operational backbone of the company's federal footprint—the source of recurring task-order opportunities in soil testing, sediment analysis, groundwater sampling, grain size characterization, and water chemistry analysis at named locations including Fort McCoy, Wisconsin; Johnson Island; Fountain City; Thief River Falls, Minnesota; and Goose Bay.

Representative prime work includes a $436,048.94 purchase order from the Department of Defense Southwest Region for water and wastewater laboratory analysis at Fort McCoy, Wisconsin (April 2025 through March 2030, with four twelve-month option periods), a $5,330 BPA call from Humphreys Engineer Center Support Activity for explosives site analysis at Tyson AOC 7 (January 2025), a $15,888 five-year purchase order from the U.S. Forest Service Region 9 for potable water testing at Chequamegon-Nicolet National Forest including approximately 200 annual samples for nitrates and coliform (March 2024 through February 2029), and a $52,784.17 option-year exercise with the Department of the Interior Midwest Region for water chemistry analysis services in Ashland, Wisconsin (March 2023 through February 2028).

Activity trajectory shows growth from a five-award baseline in 2022 to a peak of 23 awards in 2024, followed by a decline to 14 awards in 2025 and only 3 awards recorded in 2026 (through May)—suggesting either a data lag or a contraction in new task-order issuance. The company faces minimal near-term recompete pressure; only two awards are scheduled for ultimate completion within the next twenty-four months, carrying combined potential value of $58 thousand. However, the substantial volume of work on multi-year IDIQs and BPAs with completion dates extending to 2028, 2029, and 2030 means that recompete activity will concentrate in the 2027–2028 and 2028–2029 windows as those larger parent vehicles approach their ceiling dates or renewals.

CT Laboratories subcontracts to prime environmental remediation contractors, including Jacobs Engineering Group, Jacobs Government Services Company, Ch2M Hill, Weston Solutions, and Specpro Professional Services. The company performs testing-laboratory services on larger CERCLA remediation and environmental-site-assessment contracts, such as the Velsicol Chemical Corporation Superfund Site (Great Lakes Architect Engineer Services) through Ch2M Hill, remedial action at American University Spring Valley formerly used defense site through Weston Solutions, and site-wide sampling and analysis at NASA Marshall Space Flight Center through Ch2M Hill. The subcontract work represents approximately 11% of the company's recent award footprint and leverages the company's laboratory and field-testing capabilities to support prime contractors' broader environmental-services delivery.

CT Laboratories' capability portfolio, grounded in its NAICS concentration, centers on testing-laboratory services (238 of 290 awards) including soil and sediment characterization, water-quality analysis, contaminant testing, and environmental-compliance sampling. Secondary capabilities include geophysical surveying and mapping (22 awards) and remediation-support services (17 awards). The company's service-delivery model operates from its Baraboo, Wisconsin laboratory with field mobilization to project sites across the Midwest and subordinate locations in Wisconsin, Minnesota, and Iowa to support Army Corps civil-works projects, military-installation environmental compliance, and civilian-agency potable-water monitoring.
