About the company
August Mack Environmental, Inc., an Indianapolis-based environmental consulting and remediation services firm, operates as a prime contractor (96% of recent awards) delivering industrial hygiene testing, wastewater treatment, environmental site remediation, and hazardous materials surveys to federal agencies under small-business set-asides and full-and-open competition. The company is a for-profit Subchapter S corporation with a named subsidiary, Environmental Field Services, Inc., and competes across environmental consulting (14 awards), hazardous waste treatment and disposal (4 awards), and remediation services (3 awards) within NAICS 562910 and PSC categories spanning environmental remediation, water quality analysis, and environmental assessments.
August Mack's customer base concentrates around two anchor programs. The Department of the Army Corps of Engineers accounts for $18.4 million in combined potential value across a single-award Indefinite Delivery Contract valued at $18.4 million (awarded March 2025, running through March 2030) for wastewater treatment plant operation and maintenance at the Indiana Harbor and Canal Confined Disposal Facility in East Chicago, Indiana, plus two task orders under a Corps Engineering District Chicago vehicle totaling $1.5 million. The Department of Agriculture Forest Service Region 9 contributes $7.5 million across two awards, anchored by a $7 million multiple-award Blanket Purchase Agreement (awarded October 2024, running through October 2029) for environmental response services at the Allegheny National Forest in Pennsylvania. The top five customer agencies by potential value account for 99% of combined dollars. Recent task-order activity under these vehicles includes a $1.04 million delivery order for temporary wastewater treatment lease and operation at Indiana Harbor (awarded June 2025, Total Small Business set-aside) and a $542,625 BPA call for a CERCLA time-critical removal action at Alf Kane Field in Warren, Pennsylvania (awarded July 2025, Total Small Business set-aside).
August Mack sits on two primary IDVs: the $18.4 million single-award contract with the Army Corps of Engineers (3 task orders), and the $7 million Forest Service BPA (1 task order). The vendor also carries a $3.1 million General Services Administration Federal Acquisition Service award and places nine task orders under the Federal Supply Schedule GS10F0074W, generating $305 thousand in combined potential value. Activity has accelerated in 2025–2026 (five awards in 2025, one in 2026) from a historically sparse profile (one award each in 2021, 2023, and 2024), with combined potential value across all 24 awards reaching $30.9 million, though only $2.7 million obligated to date (9% of ceiling). The vendor's recent award history reflects Total Small Business set-asides on wastewater and remediation delivery orders, full-and-open BPA calls on environmental response, and Women-Owned Small Business set-asides on industrial hygiene testing, indicating flexible posture across set-aside categories rather than a single dominant category. Place of performance spans East Chicago, Indiana (wastewater treatment), Warren, Pennsylvania (CERCLA remediation), and Columbus, Ohio (industrial hygiene surveys), reflecting regional project-based work rather than centralized service delivery.
