Aquatic Environment Consultants, Inc.

Aquatic Environment Consultants, Inc., doing business as AEC, is a small-business-set-aside federal contractor headquartered in Chambersburg, Pennsylvania, that provides invasive aquatic plant management, herbicide application, and environmental water-quality services as a prime contractor across Army, interior, and natural-resources customer agencies. AEC is a for-profit Subchapter S corporation that competes predominantly under small business set-asides (8 of 13 recent awards carry total small business designations); the remaining awards are full-and-open or unrestricted competitions. The vendor's footprint spans environmental consulting services (8 awards, predominantly NAICS 541620), landscaping and grounds maintenance (3 awards), and forestry support (1 award).

AEC's customer concentration is moderate and balanced across two dominant agencies. The Department of the Army Corps of Engineers Baltimore District accounts for 5 awards and $477 thousand in combined potential value, primarily herbicide application and aquatic plant control work at Raystown Lake and other Pennsylvania water bodies. The Department of the Army Test and Evaluation Command also accounts for 5 awards and $213 thousand, anchored by a $36 thousand full-and-open contract awarded September 23, 2024, for submerged invasive weed eradication at Aberdeen Proving Ground's underwater test facility through September 2027. The Department of Agriculture Forest Service, Department of the Interior Fish and Wildlife Service, and NASA Goddard Space Center round out the active set with one award each. Across all thirteen recent awards, AEC has obligated $754 thousand against a combined potential value of $793 thousand (95% execution).

Recent representative work includes a $20 thousand small-business-set-aside purchase order from Fish and Wildlife Service Region 5 (awarded June 24, 2026) for invasive species control—Curly-Leaf Pondweed, Eurasian watermilfoil, and Spatterdock treatment—at Erie National Wildlife Refuge near Guys Mills, Pennsylvania, running through September 2027; a $117 thousand small-business-set-aside contract from Army Corps of Engineers Baltimore District (awarded June 9, 2025) for aquatic herbicide application at Hesston, Pennsylvania; and a $114 thousand small-business-set-aside contract (awarded May 3, 2024) for herbicide application at Raystown Lake covering approximately 68 acres. Activity is sparse but steady—one award in 2022, one in 2023, two in 2024, one in 2025, and one most recently in June 2026. Two awards with combined potential value of $56 thousand face ultimate completion within the next twenty-four months and are therefore exposed to recompete. AEC operates exclusively as a prime contractor with no subcontract footprint in the source data.
