About the company
Pars Environmental Inc., a subsidiary of Onterris Government Solutions, Inc., operates as a prime contractor delivering environmental consulting, remediation, assessment, and engineering services to federal agencies across 43 distinct customer organizations, competing predominantly under full-and-open procurement rather than set-aside designations. The company is based in Trenton, New Jersey, and operates Pars Gannett Fleming Joint Venture as a subsidiary; it has logged 221 awards across the past twenty-five years with a combined potential value of $73.12 billion, though this figure is heavily skewed by a small number of Navy awards with exceptionally large ceilings and does not reflect the company's typical contract scale or earned revenue.
Pars Environmental's customer base is concentrated among three distinct buying patterns. The top-five customer agencies by award count account for 60% of awards and include the Army Corps of Engineers' Louisville and Philadelphia districts (55 and 30 awards respectively, $23.2 million and $20.3 million combined potential value), the EPA's Office of Research and Development (30 awards, $12.7 million), EPA Region 2 (9 awards, $8.7 million), and the Navy's Office of Naval Research (9 awards, $210 thousand). By potential-value ranking, two Navy commands—Naval Sea Systems Command (2 awards, $72.55 billion) and Naval Facilities Engineering Command (5 awards, $31 million)—dominate the dollar profile, but these are outlier ceilings. The practical workload concentrates with the Army Corps of Engineers districts and EPA regional offices, where Pars Environmental fields 119 awards with $71.7 million in combined potential value. Environmental consulting services, engineering services, and remediation services account for the bulk of the award volume (178 awards combined across the three categories).
Recent named work includes a $3.247 million delivery order from EPA Region 2 for targeted brownfields assessments across the region under the EPA Remedial Acquisition Framework: Environmental Services and Operations (ESO) master IDIQ (set aside for Total Small Business, placed September 2026, performance through September 2029); a $5.5 million delivery order from EPA Region 3 for operation and maintenance at the Atlantic Wood Industries Superfund site in New Jersey (awarded January 2022, completion January 2027); and a $594,819 delivery order from EPA Region 2 for groundwater investigation at the GEMS Landfill Superfund site in Blackwood, New Jersey (awarded February 2024, completion February 2025). Pars Environmental places work under the GSA Multiple Award Schedule (56 task orders, $11 million combined potential value), Army Corps IDIQs W912QR14D0006 (24 task orders, $1.7 million), W912QR09D0041 (12 task orders, $3.5 million), and EPC17009 (24 task orders, $1.7 million).
Award activity has been episodic: five awards in 2020, nine in 2021, three in 2022, one in 2024, and one in 2026. Only one award (the $5.5 million Atlantic Wood Industries delivery order) completes within the next twenty-four months and faces recompete. Pars Environmental operates as a pure prime across its portfolio (100% of awards), with minimal Service Contract Inventory activity: SCI-reportable invoiced revenue totaled $927 thousand in FY2023 only, delivered by roughly 0.5 FTEs across that fiscal year. On SCI-reportable prime contracts, median government-paid hourly rates ran around $252.61/hr, with senior labor pricing through $309.80/hr. The company engages subcontractors for approximately 16% of prime-contract hours on average, with two named subs reported across the SCI dataset.
