About the company
Environmental Science Services Inc., doing business as ES2, an SBA 8(a) certified small disadvantaged business headquartered in Denham Springs, Louisiana, is a prime contractor (86% of recent awards) delivering environmental consulting, project management, surveying, and technical support services to the U.S. Army Corps of Engineers. ES2 is a minority-owned, Hispanic American-owned for-profit entity with an 8(a) certification expiring January 25, 2030, and competes predominantly under 8(a) sole-source and competitive set-asides across its prime footprint.
ES2's federal work concentrates overwhelmingly on the Army Corps of Engineers. The top five customer agency segments account for 100% of recent awards: the Department of the Army Corps of Engineers (21 awards, $27.2 million combined potential value), the Engineering District New Orleans (7 awards, $6.3 million), the Engineering District Vicksburg (2 awards, $4.9 million), Civil Works (1 award, $267 thousand), and the Centers for Disease Control and Prevention (5 awards, dollar values not disclosed). The two customer-ranking frames align tightly—the Army Corps dominates both volume and dollars. Recent representative work includes a $3.31 million delivery order from USACE for environmental project support, scheduling, and master plan services (awarded September 10, 2025, completion December 10, 2026); a $2.05 million delivery order for quality assurance mission specialist services supporting Hurricane Helene debris removal in western North Carolina (awarded May 20, 2025); and a $1.99 million 8(a) sole-source definitive contract for lock expansion joint coring and sealing in New Orleans (awarded September 19, 2022, completed June 2023).
ES2 holds five single-award indefinite delivery contracts with the Army Corps, each valued at $4.5 million. Three carry 8(a) sole-source set-asides: a $4.5 million IDIQ for environmental professional support services and 8(a) civil works project management support including interagency and international programs (awarded July 16, 2025, completion July 15, 2030); a $4.5 million IDIQ for emergency management support, professional services, and natural resources management (awarded January 31, 2024, completion January 30, 2029); and a $4.5 million IDIQ for natural resources management and environmental services (awarded September 28, 2023, completion September 27, 2027). Two additional IDIQs carry no set-aside: a $4.5 million contract for project management support across the Vicksburg District area of responsibility (awarded June 24, 2026, completion June 16, 2031) and a $4.5 million contract for professional support services in the New Orleans area (awarded September 29, 2023, completion September 28, 2028). Against these five vehicles, ES2 placed 20 task orders valued at $12.4 million combined potential value. The top two vehicles by ordering activity are Indefinite Delivery Contract W912P823D0012 (10 task orders, $2.6 million combined potential value) and W912P823D0015 (5 task orders, $4.5 million combined potential value).
ES2's capability portfolio spans surveying and mapping services (11 awards), technical consulting including environmental assessments and data analysis (6 awards), engineering services (4 awards), and environmental consulting (3 awards). Concrete work examples include UAS LIDAR survey and conventional survey data collection for three Atchafalaya River dredged material disposal sites near Amelia, Louisiana (awarded July 13, 2026, completion July 12, 2027, ceiling $395,979); LIDAR surveys in Orange, Texas (awarded December 17, 2024, completion September 14, 2027, ceiling $32,180); programmable logic controller repairs and hydraulic power unit maintenance on lock gates (awarded August 5, 2022, ceiling $142,400); and office trailer rental support in Lake Charles, Louisiana (awarded August 4, 2022, completion August 3, 2025, ceiling $266,852 for base plus option years). Recent activity shows growth from five awards in 2022 to eleven in 2025, with four awards in 2026 year to date. Nine awards (combined potential value $5.6 million) face ultimate completion within the next twenty-four months and therefore recompete risk in that window.
In its subcontractor role, ES2 receives federal grant sub-awards from the Louisiana Department of Health as a sub-recipient under the Centers for Disease Control and Prevention funding stream. ES2 provides advanced geographic information systems analyses and expert consultation on spatial analysis to support environmental epidemiology programs focused on private well water safety, population exposure assessment, and data standardization. Four grant sub-award actions are present in the source, all for GIS analysis and well-registry data work, with award dates in June 2022, 2023, and 2025.
ES2 holds a single named subsidiary: Chustz + ES2 Joint Venture, LLC, a minority-owned, self-certified small disadvantaged business and Hispanic American-owned limited liability company structured as a small business joint venture.
