are the result of being the pioneers in New England, over ten years ago, in the use of direct push sub-surface sample collection tools and techniques. We continue to use and improve on state of the art direct push tools. We think that when our tools are coupled with our staff and project experience, we are time and cost effective while maintaining a high quality of service.

In addition to the low site impact of our direct push systems and the minimal soil or water disposal as a result, we find the new direct push systems to be able to provide a broader range of services.

 A few of the these services, some of which are unique to ESN, include:

• Continuous or discrete subsurface soil sampling,
• Discrete vertical interval groundwater sampling,
• Active and passive soil vapor installation and sampling,
• Subsurface injection of aquifer restoration materials,
• Gamma logging within our direct push tooling for stratigraphy data
• Top of bedrock delineation,
• Installation and data collection for remedial design data, e.g., soil vapor extraction, free product
• delineation, and groundwater recovery data.
• We are continually improving our tools and techniques to improve the speed and effectiveness of the data provided. We look forward to challenging site constraints and are always open to discussing alternative methods in order to collect the data you desire.
