Pollution Prevention Services

Geosyntec helps clients manage risk while meeting their organizational goals for environmental stewardship and financial management. Our environmental management and pollution prevention services build compliance solutions, generate defensible valuations of impaired properties, distinguish between potential and actual environmental risks, and reduce energy and water-resource utilization.

Our environmental management systems (EMS) and compliance practice relies on experts with detailed knowledge of businesses, permitting close evaluation and the generation of specific, actionable reviews and recommendations. Geosyntec utilizes a holistic approach to assist facilities operators in safely and effectively meeting environmental goals while complying with relevant laws and regulations. Our EMS and compliance service offerings encompass water footprinting and use-minimization strategies; waste compliance management program implementation; and process safety management (PSM), environmental health-and-safety (EH&S) and treatment, and storage and disposal facility (TSDF) audits.

Geosyntec's technical expertise, regulatory compliance experience, and collaborative project management approach prepares our practitioners for the most complex and challenging environmental management projects. One notable success was the establishment of a comprehensive environmental management system for the U.S. General Services Administration's Denver Federal Center, an expansive, 640-acre campus hosting 28 federal agencies and nearly 7,000 employees. The center is the largest concentration of federal agencies outside of Washington, D.C., and Geosyntec's practitioners helped GSA leaders achieve measurable improvements in environmental performance and cost savings by guiding the development of a sustainable campus.

In another large-scale project, Geosyntec practitioners turned their attention to the 342-acre Potomac Yard in Alexandria, Virginia, the site of an historic rail yard that had been de-listed from Superfund and was being prepared for redevelopment. Geosyntec's expertise and comprehensive understanding of environmental impacts across the site was used during property transaction negotiations for buyers to make timely and informed financial decisions. Our practitioners helped the client delineate the nature and extent of residual wastes and impacted soil at the site and identify a disposal alternative for more than 50,000 cubic yards of cinder ballast and other materials. Subsequently, Geosyntec personnel remained on hand during redevelopment activities to provide geotechnical recommendations during contractor excavations; to develop and oversee the implementation of a soil characterization and disposal plan; and to provide oversight of a human health and ecological risk assessment.
