Environmental Engineering

We care about the environment. TD&H Engineering works with our clients and regulatory agencies to determine appropriate strategies to comply with permit requirements and provide creative, yet realistic alternatives to solve drainage issues and improve the environment.

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

We also believe that preventing damage will have a more profound benefit to the environment and bottom line, so we offer a full range of prevention and risk reduction measures. A culture of environmental awareness runs through all of our services.  As an established civil engineering firm, TD&H Engineering has significant experience in waste water treatment, storm water pollution prevention plans, and various water resources projects.  TD&H Engineering has personnel with experience in projects beyond the abilities of many traditional civil engineering firms, including projects involving agricultural chemicals, leaking underground storage tanks, mine waste remediation, and hazardous wastes.

Environmental problems can be solved more efficiently with a one-stop solution.  Our engineers work closely with our environmental and industrial hygiene professionals to identify specific environmental impacts and prepare in-place solutions that minimize project delays or cost overruns.

Being a mid-size Montana-based company has the advantage of improved intracompany communication and considerable cross training.  As a result, we provide quicker, more cost effective service to clients where a geotechnical investigation has to take place in an environmental context (including Superfund sites).  Our environmental personnel are accustomed to working as part of an interdisciplinary team.
