What O6 Environmental Services does

O6 Environmental Services is a St. Louis-based Certified Small Business (NAICS 562910) operating as a nationwide environmental contractor. The company provides hazardous waste management, environmental remediation, industrial cleaning, demolition, and emergency response services to commercial, industrial, and government clients. Core technical capabilities include in-situ soil stabilization/solidification (ISS), in-situ chemical oxidation (ISCO), deep soil mixing, enhanced bioremediation, electrokinetic remediation, thermal treatment, and nanoremediation — typically deployed at legacy industrial contamination sites such as manufactured gas plants (MGPs), coal ash ponds, brownfields, refineries, and chemical facilities. The company also operates two wholly-owned subsidiaries — Illini Environmental (waste management and recycling) and Remediation Services Inc. (RSI, soil and groundwater remediation) — extending service breadth into adjacent waste and remediation verticals.

The company generates revenue through project-based professional services contracts, with pricing determined per project via quote. Notable reference projects include 90,000 tons of impacted soil excavated and disposed at the Ameren Illinois Litchfield FMGP site, 700,000 gallons of MGP-impacted groundwater treated via onsite wastewater treatment plant, and 60,000 cubic yards of coal-tar-impacted soil at the Big Muddy MGP project for AECOM/ComEd. The cumulative track record is 3,500+ projects across 35+ years of stated industry expertise. The website claims 100+ expert team members, while firmographic data lists 51–100 employees.

The go-to-market motion is enterprise field sales, targeting utilities, oil & gas, manufacturing, construction/real estate, transportation, government, agriculture, mining, healthcare, and waste management verticals. Distribution is direct via project bids and contractual engagements, with no public pricing tiers disclosed. Marketing is supported by content (educational blog on remediation, PFAS, EPA compliance, brownfield redevelopment), LinkedIn, Facebook, and Twitter presence, and prominent phone-based lead capture. In August 2025, the company received a private equity investment from Quad-C Management to fund geographic expansion and service line growth.

• WSP: International engineering consultancy with significant environment, soil, and groundwater remediation practices. Comparable as a remediation program designer and oversight partner for utility clients.
• GHD: Global engineering, architecture, and environmental consulting firm with remediation and contaminated land capabilities. Comparable to O6's site cleanup, MGP, and CCR remediation offerings.
