What EnviroScience does

EnviroScience, Inc. is a Stow, Ohio-based environmental consulting firm founded in 1989 by Marty Hilovsky as a biological toxicity testing laboratory and expanded into a full-service ecological, engineering, and restoration practice. The firm employs 150+ biologists, commercial divers, environmental scientists, and engineers delivering twelve core service areas including aquatic surveys, ecological restoration, commercial diving, laboratory bioassay and taxonomy analysis, threatened and endangered species surveys, stormwater and NPDES compliance, emergency response, and sustainability consulting. Service delivery leverages specialized field equipment — electrofishing gear, water quality meters, GPS/GIS, SCUBA, vibracore sediment sampling, and ADCI-accredited commercial diving vessels — supported by an in-house bioassay and taxonomy identification laboratory.

The company operates a sales-led, project-based professional services model with quote-based, multi-year contract pricing tailored to scope, complexity, and duration. Revenue is generated through direct engagements with federal, state, and municipal government agencies (USEPA, U.S. Forest Service, multiple state DOTs and EPAs), railroad operators (notably CSX Transportation), utilities, mining and manufacturing firms, engineering firms, and select private clients. Documented customers include CSX Transportation, Lockheed Martin, Dominion East Ohio Gas, USEPA, Ohio/Pennsylvania/Tennessee DOTs, West Virginia DOH, Ohio EPA, U.S. Forest Service, and Kentucky DEP. Service delivery extends nationwide through eight regional offices plus Guam, covering specialties such as freshwater mussel salvage, endangered bat surveys, NPDES permit support, PFAS sampling and remediation, and design-build stream and wetland restoration. In 2022, EnviroScience joined ACRT Services, Inc., a 100% employee-owned parent, while retaining its brand, team, and operational autonomy under founder Marty Hilovsky's retirement.
