"I would like to take the opportunity to offer a formal recommendation for Environmental Probing Investigations, Inc. (EPI) As a professional in the environmental consulting field, I have worked with EPI for approximately five plus years. They perform their work in a health and safety conscious manner, are knowledgeable of the NJDEP drilling regulations, and are client friendly. EPI provides both reliable men and equipment who work with the consultants, not against them. I feel tat EPI is a dependable, professional drilling firm with competitive costs, flexible availability, and excellent services. I definitely recommend EPI to anyone for quality drilling services."

"I've been using EPI over 9 years since their startup in 1994. I have been impressed with the customer service, quick response time, rig availability, the consistency of their experienced drillers and management's ability to accommodate changing schedules. They are the sort of company that will go the extra mile in the field to get the job done. Another important facet that I have come to rely on with EPI is their knowledge of Health and Safety procedures in the field. When my clients require competitive bids, EPI has consistently won over their competition. In my 9 years using EPI, I have tried other Geoprobe firms just to check on the competition and, to be honest, there is no comparison when it comes to price, personnel and service. When a Geoprobe job comes up, I automatically call EPI because I know that I will get fast, competitive quotes, competent, knowledgeable drillers and great service. Keep up the good work!"

"I wanted to take a few minutes to thank you for the quality services that Environmental Probing Investigations, Inc. (EPI) has provided on my projects. I have worked with the EPI team for over thirteen years and have always received the highest level of service. I greatly appreciate the dedication to completing the job that EPI provides, from the driller’s helper all of the way up the ladder to you. EPI provides a great network of resources for my projects starting with Tony when I initially outline my scope of work so he can prepare a proposal, to Joe who provides updates as the start of the project approaches, to the crew in the field, and all the way to Carol for providing answers on invoicing and requests for records. I also appreciate the fact that this core team, including yourself, has been there from the start of our relationship and those people are still there today. I believe that reflects highly on EPI and the stability of the company. I also greatly appreciate the experienced and hardworking crews that work along me and my fellow staff while in the field. I have been fortunate enough to work with AJ, Warren and Bob for several years and always found them to be extremely professional, knowledgeable, and dedicated to safety. It is of great comfort to me to know that the job will be done correctly in the field and if there are issues encountered, that your crew has the experience to find a solution. I am also looking forward to the new online resources that you will be offering. I feel that providing online access to invoices and drillers records is a great example of how EPI goes above and beyond. I am not aware of any other drilling companies that provide that service and I think it further demonstrates the attitude of EPI to provide exceptional customer service. Thank you again for the quality work over the years and I am looking forward to more opportunities to partner with EPI in the future."

Just wanted to take the time to say thanks to EPI and Jim for a fantastic job done out at the Dunellen site.  I usually have good experiences with your guys, but Jim really went above and beyond on this one.  Not only did he perform all of his duties as a driller, but he was also really helpful getting the site set up every day and aiding us in our tasks throughout the day.  It really made the project go that much easier, especially on Thursday when we were a man short, it was almost as if he was one of our field techs.  Please pass on my many thanks to Jim and we look forward to working with him again in the future.
