Southwest Hazard Control Inc.

Southwest Hazard Control Inc., a woman-owned small disadvantaged business (WOSB) and self-certified SDB based in Tucson, Arizona, provides asbestos abatement, hazardous waste removal and disposal, pharmaceutical waste management, mold remediation, and facility cleaning services to federal agencies as a prime contractor (99% of recent awards) competing primarily full-and-open against all vendors rather than under set-aside vehicles.

The company operates as a for-profit Subchapter S corporation with a longstanding federal contracting footprint anchored in environmental remediation and facility support services. Southwest Hazard Control Inc. has served 24 distinct federal agencies over its tenure, with recent activity concentrated at the Department of Veterans Affairs Veterans Integrated Service Network 22 (VISN 22) in Tucson, Arizona; Air Combat Command at Davis-Monthan Air Force Base in Arizona; the General Services Administration Public Buildings Service; the Department of the Interior National Park Service Intermountain Region; and the Department of the Interior Bureau of Indian Affairs Western Region. Representative prime work includes a $54.6 thousand delivery order from VA VISN 22 for pharmaceutical waste and disposal services (October 2024), a $57.5 thousand firm fixed-price call from Air Combat Command for housekeeping and waste treatment/storage at Davis-Monthan Air Force Base (October 2023), a $6.7 thousand purchase order from VA VISN 22 for asbestos abatement services in Phoenix, Arizona (February 2026), and a $57.4 thousand emergency hazardous waste removal order from VA VISN 22 (May 2023). Recent sub work includes asbestos abatement and remediation services to the Department of Energy Office of Environmental Management under its nationwide deactivation, decommissioning, and removal procurement (September 2025 and March 2025).

Customer concentration reflects strong dependence on two agencies across two rankings. VA VISN 22 anchors the dollar concentration—25 awards carrying $1.5 million combined potential value represent 32% of the vendor's total potential value. Air Combat Command is the second-largest customer by dollars, with 35 awards valued at $862 thousand. The General Services Administration Public Buildings Service ranks highest by award count at 47 awards but carries limited dollar value, suggesting transactional micro-procurements or administrative contract holdings. The top five customer agencies account for roughly 61% of award volume and 60% of combined potential value.

Southwest Hazard Control Inc. holds a multiple-award Blanket Purchase Agreement with Air Combat Command and Air Education and Training Command valued up to $250,000 through April 2030, covering housekeeping, custodial work, laundry, dry cleaning, waste treatment, storage, building remediation, and COVID-19 cleaning across multiple Air Force installations. That BPA has generated 13 task orders worth $383 thousand in combined potential value. The vendor also places work under a GSA Multiple Award Schedule (13 task orders, $391 thousand combined potential value) and holds an Indefinite Delivery Contract 36C25821D0005 for pharmaceutical waste and disposal services at VA VISN 22 (6 task orders, $292 thousand combined potential value), as well as an additional IDC vehicle V678P4331 with 3 task orders.

Award volume has been flat to declining over the past five years—8 awards in 2022 and 2023, 7 in 2024 and 2025, and 1 in 2026 year-to-date. Only 2 awards (combined potential value $50 thousand) reach ultimate completion within the next twenty-four months, presenting minimal near-term recompete risk or opportunity. The vendor's award portfolio is heavily skewed toward small-dollar remediation and facility-support task orders rather than larger prime vehicle awards; combined obligated dollars ($10 million) exceed combined potential value ($4.7 million) by 213%, reflecting a historical baseline of invoicing against task-order ceilings.

Service Contract Inventory captures minimal SCI-reportable activity—2 records (both as subcontractor) in FY2024 representing 1.0 FTE. SCI is incomplete for this vendor and does not represent its federal services footprint; the award portfolio shows substantially higher activity than SCI captures. The vendor competes almost exclusively as a prime contractor (99% of awards) and does not lean on subcontractor delivery; its subcontractor engagements are limited to two recent Department of Energy remediation subs under a single nationwide DD&R vehicle. Corporate structure lists Southwest Hazard Control, Inc. as a named subsidiary of the parent Southwest Hazard Control Inc.
