Environmental Engineering Services
In today's environment, good planning must take into consideration a project's effect on natural resources and the impact of existing conditions on the project. With experience dating back to some of the earliest federal environmental regulations, NTH has assisted a broad range of clients with evaluating, constructing and operating facilities, in full compliance with laws and agency protocols. Moreover, we have the expertise to successfully satisfy the expectations of multiple stakeholders by developing forward-thinking, environmentally sound and cost-effective solutions.
NTH has evolved from a specialty geotechnical firm to a full-service multidisciplined geo-environmental firm. This evolution followed a natural progression based on our unique understanding of the subsurface, particularly soil and groundwater conditions. This unique combination of skills has enhanced our ability to serve our clients during design and construction phases, expediting resolution of issues.
