What Alta Science & Engineering does

Alta Science & Engineering is an environmental and infrastructure consulting firm headquartered in Moscow, Idaho, with four offices across Idaho (Moscow, Kellogg, Boise) and Washington (Spokane) and staff reporting from Oregon, Montana, Nevada, Colorado, and Alaska. The firm delivers eight interconnected practice areas covering brownfields redevelopment, civil engineering, remediation engineering, data management and visualization, ecosystems services, environmental risk assessment, site characterization, and water resources. Technical capabilities span GIS/database integration with SQL, R, Python, and Microsoft Access, LiDAR and multispectral imagery analysis, geostatistical evaluation, and a proprietary forensic contamination source-tracking methodology using lead isotope markers for mining waste attribution.

The company generates revenue through professional services contracts, with over 85% of business sourced from federal, state, tribal, and local government clients including the US EPA, US Fish and Wildlife Service, US Forest Service, US Bureau of Reclamation, US Department of Energy, US Army Corps of Engineers, Idaho DEQ, Washington Department of Ecology, and tribal governments including the Coeur d'Alene and Nez Perce Tribes. The firm is SBA HUBZone certified and was 100% employee-owned until its acquisition by WSB LLC announced on May 14, 2026. Notable engagements include the Bunker Hill Mining and Metallurgical Complex Superfund Site, the Bayhorse State Park redevelopment, the Palouse Basin Aquifer Study, and science advisory work for Clark County Nevada's Multi-Species Habitat Conservation Plan covering 78 species.

The firm operates a relationship-driven B2G sales motion built on 35+ years of regulatory relationships, multi-state professional engineering licensure, and a workforce of 60+ licensed engineers, geologists, hydrogeologists, ecologists, and GIS specialists. Marketing is conducted primarily through industry conferences, technical publications, and board service rather than traditional commercial channels. Cumulative contract value includes $60M+ in Idaho infrastructure projects and 500,000+ environmental samples collected over the past decade.

• Aspect Consulting: Pacific Northwest environmental and geotechnical consulting firm with comparable size, service mix (site assessment, remediation, water resources), and government client base; often competes with Alta on Washington and Oregon state/local work.
• Brown and Caldwell: Employee-owned environmental engineering consultancy focused on water, environmental remediation, and federal/state infrastructure — similar business model to Alta with comparable reliance on government contracting and similar mid-size scale.
• Kleinfelder: Engineering, environmental, and scientific consulting firm with comparable site characterization, remediation, and water resources practices; serves federal/state/municipal clients similar to Alta across the western U.S.
• Geosyntec Consultants: Employee-owned environmental consulting firm with deep technical practices in site investigation, remediation, water resources, and risk assessment — direct competitor for federal Superfund and mining remediation work, with comparable differentiated technical expertise.

Broad incumbents

• Tetra Tech: Largest pure-play environmental and water engineering consulting firm globally; offers the full suite of services Alta provides plus much broader international reach, larger federal prime contract capacity, and deeper bench of senior technical staff.
• AECOM: Global engineering and environmental services firm with a major environmental remediation and federal services practice; competes for the same EPA, USACE, and Superfund prime contracts as Alta but at a vastly larger scale.
• Jacobs Solutions: Global professional services firm with a sizable environmental and infrastructure practice serving federal clients; competes for EPA and DoD environmental work that Alta also targets but with national scale and significantly larger budget capacity.

Others
