Horizon Environmental Services, Inc.

Horizon Environmental Services, Inc., doing business as Horizon Environmental Enterprises, is a woman-owned small business providing hazardous waste characterization, packaging, disposal, and collection services to federal defense and civilian agencies as a prime contractor under Total Small Business set-asides and full-and-open competition. Based in Cranberry Township, Pennsylvania, and operating as a Subchapter S corporation, Horizon competes predominantly under small-business set-asides across its federal footprint, with nearly all recent work routed through five large indefinite delivery contracts with the Defense Logistics Agency Disposition Services.

Horizon's capability portfolio centers on hazardous and non-hazardous waste collection, transportation, disposal, environmental testing, and technical assessments at military installations and federal logistics facilities. Representative work includes a $74,520 two-year hazardous waste removal contract at the Atlantic Oceanographic and Meteorological Laboratory in Key Biscayne, Florida (National Oceanic and Atmospheric Administration, awarded September 2026), a $34,650 purchase order for hazardous waste characterization and packaging at NOAA's Sandy Hook and Milford laboratories (awarded September 2026), and a $393,750 delivery order for waste management services at Tinker Air Force Base under DLA Disposition Services (awarded April 2026). The company also manages specialized waste streams including universal wastes, compressed gases, polychlorinated biphenyls (PCBs), and per- and polyfluoroalkyl substances (PFAS) across military logistics hubs.

Customer concentration is extreme. DLA Disposition Services accounts for 4,931 of 4,987 total awards (99 percent) and $155.9 million of $166.5 million combined potential value. Secondary customers are negligible by comparison: the Department of the Army Materiel Command TACOM Life Cycle Management Command (3 awards, $2.5 million), the Department of the Army Materiel Command Contracting Command Detroit Arsenal (20 awards, $1.4 million), the Department of the Navy (1 award for NAS Corpus Christi subcontract work), the National Oceanic and Atmospheric Administration (2 awards, $109 thousand), and the Department of the Air Force Reserve Command (1 BPA, $150 thousand through July 2029). This concentration reflects Horizon's positioning as a specialized DLA-dependent firm with minimal diversification.

Horizon holds five large indefinite delivery contracts with DLA Disposition Services: SP450020D0018 (1,346 task orders, $12.2 million combined potential value), SP450023D0013 (640 task orders, $22.2 million), SP450015D0009 (988 task orders, $8.4 million), SP450010D0011 (580 task orders, $8.1 million), and SP450011D0003 (470 task orders, $4.2 million). These five vehicles collectively support the vast majority of task order activity. Horizon also holds a single-award Blanket Purchase Agreement with the Department of the Air Force Reserve Command for wastewater testing and tank cleaning at the 911th Airlift Wing base in Coraopolis, Pennsylvania, valued at $150,000 through July 2029.

Activity has been volatile. Awards per year peaked at 614 in 2024, declined to 379 in 2025, and dropped sharply to 115 in 2026—a trajectory consistent with seasonal task order award patterns in the DLA universe. Within the next twenty-four months, 138 awards with combined potential value of $5 million reach ultimate completion and face recompete. Horizon operates exclusively as a prime contractor with no material subcontract footprint. The company competes predominantly under Total Small Business set-asides, with occasional full-and-open delivery orders on the same DLA vehicles, reflecting DLA's mixed award practice within single-award and multiple-award IDIQs.
