GSI Water Solutions, Inc., is a specialized groundwater, environmental, and water resources consulting firm. We help clients protect and manage shared water resources with solutions that are practical, forward thinking, and built on a foundation of good science. In 2000, our three founders left their careers at a large consulting firm to form a small client- and employee-focused company. Today, we are an employee-owned S-corporation with more than 50 staff members across five offices in two states. Since our founding, we have worked with more than 300 clients in the public and private sectors, from city governments to international companies. We are experts in hydrogeology, hydrology, remedial engineering, water resources, and environmental science. We also offer complete in-house GIS, graphics, technical writing and editing, and document production.
