We have provided responsive, cost-effective solutions on well over 1000 projects with field offices located in Sonoma County California and Dane County Wisconsin. On all projects, we strive to serve our client's needs Professionally, Ethically, and Efficiently.

Our Professional Geologists’ expertise includes real estate due diligence, environmental site assessments, contaminated site investigations and remediation, hazardous materials management, disaster assistance and cleanup, regulatory permitting and compliance and more.

Owner and Principal Geologist, David L. Bush, is directly involved in each project, assembling a project-specific team to best serve the needs of Clients. EGS provides our Clients with the individualized service of an independent professional, with the depth and support found at larger firms, but without the associated layers of middle management and resulting cost markups.

Our experienced associates are licensed professionals, provide full technical support and project management to keep projects on track, in compliance and on budget. The goal of our approach is to relieve our Clients from diverting their valuable time and resources away from their lives and work.
