O&M

What O&M does

O&M, Inc. is a privately held, multi-discipline environmental services company founded in 1988 and headquartered in Knoxville, Tennessee, with additional operations in California. The firm delivers an integrated four-part service portfolio spanning Assessment & Investigation Services (site assessments and Remedial Investigation work plans for industrial sites, CERCLA/Superfund, RCRA Corrective Action, and state-led sites), Remediation Services (design and implementation of technologies including groundwater pump-and-treat, soil vapor extraction, air sparging, in-situ chemical oxidation, bio-stimulation/augmentation, thermal destruction, landfill closure, geosynthetic cap installation, and wastewater treatment), Operations & Maintenance Services (turn-key site operations staffed by licensed wastewater treatment operators, including sampling, regulatory interaction, and grounds maintenance), and Design Reviews & Performance Audits (independent compliance, performance, and cost/benefit evaluation of remediation systems).

The company is built on a staff of engineers, geologists, environmental scientists, technicians, and licensed wastewater treatment operators that provides in-house coverage from initial site characterization through long-term operational closure. O&M serves industrial and commercial facilities (gas stations, shopping centers, petroleum terminals, industrial sites), regulated waste sites under CERCLA/RCRA and state Superfund programs, and landfill operators requiring closure or ongoing monitoring. The firm's core differentiator is continuity across the assessment-design-build-operate lifecycle, intended to reduce long-term remediation cost by eliminating ineffective features early and easing downstream maintenance.

Commercially, O&M operates a project-based professional services model with quote-based, project-specific pricing and no disclosed public pricing. Revenue is generated through direct enterprise engagements with industrial clients, government agencies, and responsible parties, typically driven by regulatory compliance requirements or environmental incidents. The company appears to rely on direct client relationships and industry reputation rather than active digital marketing, and is affiliated with de maximis, inc. (project management and coordination) and de maximis Data Management Solutions, Inc. (environmental data management and visualization) to extend delivery capacity. No funding rounds, M&A, or institutional ownership are disclosed; the firm appears to be founder/management-owned.

Broad incumbents

• Arcadis: Arcadis is a major global environmental and water consultancy offering site investigation, remediation design, and long-term O&M under similar regulatory frameworks (CERCLA, RCRA). It directly competes with O&M for industrial and public-sector remediation mandates but at much larger scale.
• Tetra Tech: Tetra Tech is a global consulting and engineering firm with a large environmental services practice covering site assessment, remediation design, and O&M for contaminated sites. It competes with O&M on CERCLA, RCRA, and state-led cleanups but operates at significantly larger scale with federal-agency prime contract capabilities.
• AECOM: AECOM provides environmental remediation, compliance, and O&M services globally as part of a multi-disciplinary engineering portfolio. It is comparable to O&M in service scope (assessment, remediation, long-term O&M) but offers national reach, larger balance sheet, and integrated design-build-operate capabilities.

Direct peers

• Terracon Consultants: Terracon is a national environmental, geotechnical, and materials engineering firm that performs site assessments, UST removals, and remediation services for industrial and commercial clients. It is closely comparable to O&M in service mix and customer segments (gas stations, industrial sites, retail centers) but operates across more geographies.
