The firm provides interdisciplinary environmental, engineering, and technology services across three primary markets: federal government (DoD, EPA, USACE), state and municipal agencies, and private industry. Service offerings span contaminated site assessment and remediation, PFAS and emerging contaminants treatment, coastal resilience, sediment management, munitions response, natural resources management, climate change adaptation, infrastructure support, and environmental health and safety compliance. Two proprietary laboratories (Ecotoxicology Laboratory in Hunt Valley and EnviTreat Laboratory in Fayetteville, Arkansas) provide specialized testing and treatability study capabilities. The firm employs machine-learning techniques including principal component analysis and random forest classification for PFAS forensics and source attribution.
The business model is professional services fee-for-service, with project-based pricing across federal contract vehicles including cost-reimbursable, unit rate, firm fixed-price, and performance-based acquisitions. The company utilizes GSA Schedule contracts and USACE PRAC MATOC mechanisms for federal procurement, and pursues direct contracts with state, municipal, and private industrial clients. Distribution is enterprise field sales through dedicated market-focused teams, with 85% of new contract awards coming from existing customers, indicating a high-retention, relationship-driven commercial model. Marketing channels include LinkedIn, YouTube, industry conferences, and STEM/community outreach programs.
