What Epic Environmental does

Epic Environmental operates as the Australian consulting arm of Onterris (formerly Montrose Environmental), a publicly traded global environmental solutions company (ticker ONT) headquartered in the United States with operations across the U.S., Canada, and Australia. The Brisbane-based Australian entity delivers multidisciplinary environmental consulting, contaminated land assessment and remediation, water consulting and treatment, ecological and natural resource management, permitting and compliance, emergency response, and climate risk services to enterprise clients in energy, mining and minerals, infrastructure, chemical, government, manufacturing, solid waste, technology and digital infrastructure, and transportation sectors.

The firm's core technology stack rests on proprietary treatment systems rather than software: mobile treatment units for short-duration PFAS projects, modular turn-key systems engineered for fast installation, bespoke custom designs, and proprietary rinse solutions capable of treating PFAS-impacted rinse water to non-detect levels for cost-effective onsite disposal. Supporting technical capabilities include EPA-compliant stack testing and fugitive emissions leak detection services delivered via field-based laboratory operations. The competitive advantage is anchored in talent - the leadership includes Contaminated Site Auditors accredited across NSW, Queensland, Tasmania, the Northern Territory and the ACT, with principal-level staff carrying 19-30+ years of specialized experience.

The business model is a project-based, direct enterprise sales motion with quote-based pricing. Go-to-market relies on thought leadership content (the Onterris Outlook Report and topical briefs), social media presence, email newsletters, and consultative engagement with regulated-industry buyers. The firm monetizes via bespoke consulting engagements, treatment technology deployment, and laboratory analysis services. In 2025, the parent rebranded from Montrose Environmental to Onterris to unify its global brand and positioning.
