What Hydrometrics does

Hydrometrics, Inc. is an employee-owned environmental and civil engineering consulting firm founded in 1979 and headquartered in Helena, Montana. The firm serves municipalities and public agencies, engineering and consulting firms, private developers and landowners, and mining operators (hard rock, industrial mineral, and coal) across the western United States. Its service portfolio is organized into six integrated lines: civil and environmental engineering, water resources and hydrogeology, mine permitting and compliance, mine reclamation, solid and hazardous waste landfills, and technical and support services. The company also operates formal geotechnical engineering, geochemical modeling, and GIS mapping capabilities as cross-cutting technical practices.

The firm delivers work using a multidisciplinary team of scientists and engineers who apply specialized modeling tools including GMS (MODFLOW, MODPATH, MT3D, PEST), FEFLOW, Hydrus 2, AnAqSim, AQTESOLV, Geochemist's Workbench, PHREEQC, and GIS to projects involving groundwater resource evaluation, contaminant fate and transport, mine permitting under OSM and NEPA frameworks, Superfund remediation, and hazardous waste landfill design and monitoring. Documented project work includes McKinley Lake Dam decommissioning, Stillwater Mine piezometer installation, Tacoma smelter site redevelopment, Lincoln mine site construction oversight, Prickly Pear Creek realignment, and Rainbow Lake Dam inspection. The firm maintains three Montana offices (Helena, Billings, Kalispell) and field locations in Colstrip MT, Tacoma WA, and Jacksonville FL.

Hydrometrics generates revenue through project-based professional services contracts, billing for engineering consulting work scoped to client requirements across municipal, federal, private, and mining customers. The firm is 100% employee-owned, with no external parent, private equity, or venture capital backing. Leadership is centered on President Greg Lorenson, supported by senior staff in field offices; the firm recently experienced a notable leadership transition with the retirement of long-tenured principal Mike Wignot after 38 years. Over its history, Hydrometrics has executed projects across North and South America, including world-class resource developments and major Superfund remediation work.

Direct peers

• Geosyntec Consultants: Specialty environmental and groundwater consulting firm with deep hydrogeology, geochemistry, and contaminated-site practices — directly comparable to Hydrometrics' groundwater modeling, geochemical analysis, and site remediation offerings.
• Kleinfelder: Geotechnical, environmental, and engineering consulting firm serving mining, water, and municipal clients across the western US — closely mirrors Hydrometrics' mix of geotechnical, hydrogeology, and civil engineering services.
• Haley & Aldrich: Environmental and geotechnical consulting firm with strong groundwater, remediation, and mining-sector practices — directly comparable on technical specialization and client overlap.
• Tetra Tech: Large environmental, water, and engineering consulting firm providing the same core services (mine permitting, hydrogeology, remediation, water resources) — direct competitor for both prime and subcontract work.
• SLR International Corporation (SLR Consulting): Global environmental and engineering consultancy with advisory, permitting, and remediation practices that overlap Hydrometrics' mining compliance, water resources, and contaminated site work.
• Anchor QEA: Mid-size environmental and water resources consulting firm focused on contaminated sites, sediment remediation, and aquatic services — comparable specialty consulting profile to Hydrometrics.
• Brown and Caldwell: Water and environmental engineering firm with deep municipal water/wastewater practice — directly comparable to Hydrometrics' municipal water supply, stormwater, and wastewater service lines.

Broad incumbents

• Stantec: Large multinational engineering, environmental, and infrastructure consulting firm; offers Hydrometrics' core services as part of a much broader portfolio and competes for mining, water, and remediation contracts at federal/state level.
• GHD: Global engineering, environmental, and advisory firm; competes with Hydrometrics in mining, water resources, and contaminated-site work through its North American environmental practice.
• WSP: Major global engineering and environmental consultancy (parent of the former Wood Environment & Infrastructure and Golder); competes for federal mining, water, and remediation primes at the scale Hydrometrics cannot match.
