Environmental Engineering

TD&H believes in a healthy environment, healthy people, and healthy companies. Our staff works with clients and regulatory agencies to determine appropriate strategies to comply with permit requirements and provide creative, yet realistic alternatives to solve pollution problems and improve our environment.

Our environmental division encompasses a broad range of services that frequently dovetail with civil engineering projects. We understand how disconcerting it can be to receive a compliance letter or notice of violation from the US EPA or state entity, and our professionals will help you through compliance issues and act as a liaison.

TD&H believes that preventing damage will have a more profound benefit to the environment and bottom line, so we offer prevention and risk reduction assistance. A culture of environmental awareness runs through our services, and we have significant experience in wastewater treatment, storm water pollution prevention plans, ground water monitoring, and water resources projects.

TD&H’s personnel have extensive experience working with agricultural chemicals, leaking underground storage tanks, mine waste remediation, and hazardous waste characterization and disposal.

TD&H has personnel trained in wetlands delineation and stream permitting. We have assisted clients in obtaining necessary permits and fulfilling Environmental Policy Act requirements for environmental assessments, baseline studies, and alternative analysis.

As a mid-size Montana-based company, our clients benefit from improved intracompany communication and considerable cross-training. As a result, TD&H provides quicker, more cost-effective service to clients where a geotechnical investigation must take place in an environmental context (including Superfund sites). Our environmental personnel work as an interdisciplinary team.
