"We’ve used Groundwater Services International (GSI) for nearly 30 years and they have never let us down. GSI is staffed with good and easy to work with professionals. Their service levels, attention to detail, responsiveness, breadth and width of capabilities are truly excellent and world class. They can handle smaller clients and jobs as well as extremely large and complicated ones. When we sold our very large companies with an extremely short timeline, it was a real effort to get all of our properties fully delineated with Phase I’s and Phase II’s in a very short time period. They were able to pull it off very well and it was quite a feat. To me, that was real life proof of just how capable they are."
