About the company
Dongsan Environment, a for-profit South Korea-based corporation, provides environmental remediation and waste removal services to the Department of Defense's Pacific Region as a prime contractor on full-and-open (non-set-aside) awards. The vendor operates exclusively in the Korea theater, with all three recent federal awards funding wastewater and human waste removal operations at Camp Humphreys and Area III in Pyeongtaek-si, Gyeonggi-do.
Dongsan Environment holds a single-award Indefinite Delivery Contract (W91QVN25D0002) with the Army Installation Management Command Pacific Region, ceiling value $895,086.39, running through November 30, 2029. The contract covers sludge and mixed human waste removal services — pickup, transportation, and disposal of sewage, sludge, grease, human waste, soil, and sand from sewage treatment plants, lift stations, septic tanks, and grease traps at the named installations. Two delivery orders have been issued to date: a $149,802.07 firm fixed price task order awarded February 1, 2025, for sludge removal (ultimate completion November 30, 2025), and a $170,611.09 firm fixed price task order awarded December 1, 2025, representing the exercise of the first option under the contract (scheduled completion November 30, 2026). Combined potential value across all three awards is $1.2 million; $320 thousand has been obligated to date (26% of the ceiling).
Customer concentration is absolute and singular: the Department of the Army Installation Management Command Pacific Region accounts for 100% of awards and combined potential value. Activity is nascent — one award in 2024, two in 2025 — with one award ($171 thousand) facing ultimate completion inside the next twenty-four months. The vendor carries no subcontract footprint in the source data and operates entirely as a prime on this single vehicle. NAICS classification spans All Other Miscellaneous Waste Management Services; PSC codes indicate housekeeping and waste treatment services.
