Managing Environmental Liabilities and Regulatory Compliance to Protect your Long-term Risk

Environmental Consulting that Brings Peace of Mind

Aerospace is the specialty market of some of our best in-house experts. Hargis professionals have spent 40 years accumulating the experience that helps aerospace companies achieve compliance and meet their business goals related to their environmental liabilities. Hargis’ commitment is to develop practical programs for these clients that will meet current and emerging environmental compliance initiatives.

Property Acquisition and Divestiture

The purchase and sale of industrial real estate often requires expedited site investigation and remediation.  Hargis understands how to move these projects forward while protecting your interests.  Our consultants are experienced in conducting environmental investigations as part of due diligence assessments for property transfers for aerospace clients.

Environmental Investigation and Remediation

Hargis has supported some of the largest environmental investigation and remediation projects in the U.S.  We’ve partnered with potentially responsible parties to achieve site closure and delisting of Superfund sites.   Our staff of geologists, hydrogeologists, engineers, and PhDs can assist with project scope and engineering cost estimates, soil and groundwater investigations, remediation engineering, vapor intrusion assessments, and implementation of a full range of remedial technologies for soil and groundwater contamination.

Environmental Compliance and Routine Monitoring

Hargis helps navigate the regulatory framework to complete complex projects on schedule.  We have extensive knowledge of local regulatory processes, Agency representatives, and their requirements including the U.S. Environmental Protection Agency, California Department of Toxic Substances Control, California Regional Water Quality Control Boards, Arizona Department of Environmental Quality, and other State Environmental Agencies.  Our engineers, hydrogeologists, and support personnel provide routine environmental monitoring and reporting for permitting and regulatory compliance.  Our experts make data easy to understand, helping you communicate critical issues internally and externally.

Risk Management

Peace of mind comes from earning your trust by proactively managing risk, reducing long-term liability, and controlling cost.  Our model is a collaborative partnership based on decades of field and regulatory experience. Hargis is called upon regularly by clients, attorneys, and potentially responsible parties to provide technical consultation related to environmental issues. Our approach is one that involves meticulous and thorough collaboration with the various stakeholders involved in these sensitive projects. We provide environmental and litigation risk assessment as well as expert witness testimony and technical support concerning contaminant source evaluations, PRP identification, cost allocation, and cost recovery issues.

Operations & Maintenance

Environmental managers often struggle with tight budgets and limited resources.  Ensuring your remediation system performs at its peak reduces the risk of costly downtime and unexpected repair costs.  We offer comprehensive services for operations and maintenance program support for a wide range of on-site remediation systems and technologies including trouble-shooting, management and evaluation of data, preparation of regulatory documents, tracking of system operational metrics, tracking permit compliance, verification of health and safety practices, and system optimization.

Contaminants of Concern

Commercial airplane manufacturers and defense contractors are often faced with complex soil and groundwater contamination.  Our team of environmental engineers, hydrogeologists, and geologists know how to tackle these unique challenges involving:

  • Volatile and semi-volatile organic compounds
  • Metals
  • Polychlorinated biphenyls
  • Perchlorate
  • Petroleum hydrocarbons
  • PFAS and other emerging contaminants
