Aarco Environmental Services Corp

Aarco Environmental Services Corp (doing business as Aarco) operates as a subcontractor on federal environmental remediation and drilling projects, with 70% of recent awards held as a prime contractor on small environmental and geological investigation tasks. The vendor delivers specialized drilling services, site remediation design and investigation, and hazardous-waste engineering support across eight federal agencies, operating primarily through GSA schedules and small targeted environmental contracts rather than large competitive vehicles.

Aarco's recent footprint is sparse and episodic. Over the past five years, the vendor has placed one award per year in 2017, 2019, 2022, 2023, and 2025, with a combined potential value of $195 thousand across ten total awards. The gap between combined potential value ($195 thousand) and combined dollars obligated ($1.8 million) indicates that obligated work substantially exceeds initially-estimated task scope — a signal of mature, replicating task orders rather than one-time procurements. The top five funding agencies account for 70% of award count and 97% of combined potential value, with the GSA Federal Acquisition Service anchoring the dollar value at $100 thousand on a single GSA Federal Supply Schedule award (GS10F0240X), followed by the Department of Homeland Security Chief Procurement Officer ($41 thousand), the Department of Transportation Maritime Administration (two awards, $18 thousand combined), the Department of Veterans Affairs Veterans Health Administration VISN 2 ($16 thousand), and the Department of the Interior US Geological Survey ($13 thousand). EPA Region 2 holds two awards but neither carries reported potential value in the top-customer ranking.

Aarco's work centers on environmental systems protection and remediation (NAICS 541511 Remediation Services dominates at five awards; Engineering Services secondary at three awards). As a subcontractor, Aarco delivers drilling and site investigation services to AECOM Technical Services on two Superfund remediation projects — a $13 thousand sonic drilling engagement for Stewart PFAS field investigation (Oct 2022) and a Meeker Avenue remedial investigation–feasibility study waste disposal task (Sep 2023) — and to Hdr-Obg A Joint Venture on a $16 thousand architect-engineering sub for pre-design investigation and remedial design at the Peninsula Boulevard groundwater plume Superfund site in Nassau County, New York (Aug 2025). Three GSA Federal Supply Schedule task orders under GS10F0240X and two task orders under the Architect-Engineer, Hazardous, Toxic, and Radioactive Waste and Environmental Services vehicle comprise the known parent vehicle footprint. Activity is flat and project-driven rather than growth-oriented; no recompete cliff is evident in the sparse award sequence.
