I have been using EST for ground water sampling in New Jersey for several years. I have found them to be very responsive to requests for quotes, scheduling and other information, and their pricing is competitive with other sampling service providers. The quality of service and coordination with laboratories is very good. I am notified promptly when field conditions vary from the anticipated and/or requested scope of services. I highly recommend their services.

Senior Program Director, WOOD PLC
For over twenty years, EST has assisted me with various wastewater and stormwater compliance projects. As an extremely busy project manager, I have high standards and expectations for anyone I’m working with, especially when I’m entrusting them with clients I’m responsible for managing. With EST however, I never have to worry as they are always professional, quick to respond, and they take my client’s compliance needs very seriously. I highly recommend their services.

When it comes to sewer pipeline services for municipalities, we always reach out to EST. They provide competitive pricing while meeting our often demanding schedule. More importantly, EST completes quality work and quickly gains the trust of our clients. I would recommend them to anyone who needs sewer pipeline investigation work completed.

LSP Director of Engineering – Capaccio Environmental Engineering, Inc.
One of our most important clients needed wastewater sampling performed and each location had its own unique challenges. We knew EST was resourceful, flexible, had a deep bench, and a can-do attitude so we thought of them to help. The entire EST team made this project a great success for us and our client. We would not hesitate to recommend EST for these and other services as we, and our clients, have had very positive experiences working with them.
