Groundwater & Environmental Services, Inc. (GES)

Assessment Services


GES has a reputation for expertly evaluating property and facility conditions and assessing risk and liability. We help our clients make informed business decisions by identifying the factors that can advance, challenge, or modify their business strategies, whether for a single property or an extensive portfolio.

GES has successfully conducted thousands of environmental site assessments, from the routine to the complex, in a broad range of physical and geographically diverse project settings. We help our clients complete their property transactions by identifying site historical background and the existence of any recognized environmental concerns. We have an excellent record of negotiation for our clients with regulatory agencies and other stakeholders. Our experienced staff also provides geotechnical and geophysical investigations, land surveying, comprehensive permitting and audit services, wetland delineations, ecological studies, air quality and noise assessments, and air, mold, asbestos, lead, and PCB surveys.

We provide added value in the evaluation of the applicability of regulatory rules and guidelines, as well as strong advocacy to help each client work toward their business goals. Our “whole site” approach, with its emphasis on a technically-sound and defensible conceptual site model, leads to a practical and cost-effective site management strategy.
