(800) 486-3575 22 Marin Way, Unit #3, Stratham, NH 03885 Soil and Groundwater Remediation Specialists WHAT WE DO OUR LABORATORY ABOUT US USEFUL INFORMATION CONTACT US REMEDIATION TECHNOLOGIES Prev Next 123 Our Staff has Over 30 Years of Providing Results Oriented Soil and Groundwater Remediation to Our Clients XDD Environmental is a consulting firm that focuses on the evaluation, design, and implementation of diverse environmental remediation technologies for soil and groundwater. The qualitative services provided by our team of experienced engineers and scientists gives us a remarkable edge above our competitors here in the United States and internationally. It is our sincere intention to bring this wealth of experience and work ethic to each of our clients. A sampling of the remediation technologies we have innovated and successfully implemented for our clients are: Enhanced Bioremediation - Treatment for Soil and Groundwater Remediation In Situ Chemical Reduction - Treatment for Soil and Groundwater Remediation Monitored Natural Attenuation - Treatment for Soil and Groundwater Remediation In Situ Chemical Oxidation - Treatment for Soil and Groundwater Remediation Air Sparging and Soil Vapor Extraction - Treatment for Soil and Groundwater Remediation Hydraulic Capture - Treatment for Groundwater Remediation Thermally Enhanced Technologies Why Choose XDD Environmental? Consider the cost of doing the same job twice: All of our remedial services are supported by our in-house bench testing and treatability laboratory. The ability to bench test each of these remediation technologies prior to implementation, allows XDD Environmental to both identify failure mechanisms and refine anticipated costs. These technologies are discussed in detail at EPA.gov, and some successful bench test case studies are summarized here. Soil and groundwater remediation failures can be identified and avoided with proper treatability testing, design, and most importantly an experienced staff that understands how to adjust to site conditions during design and implementation stages. XDD Principals have been focused in the design and implementation of soil and groundwater remediation since subsurface remediation first gained traction in the early 1980’s. Our reputation as remediation specialists within the industry drives our clients to seek out our services, especially at high profile or technically difficult sites. National Recognition for our Expertise and Experience with Soil and Groundwater Remediation Technologies XDD Environmental and Partner Consultants Win ENR Regional Best Project Award for Thermally Enhanced Bioremediation System redesign resulted in an estimated 50% savings in electrical costs and required less general infrastructure, reducing the overall footprint of the remedy. A summary of the project and award are located here. XDD's Weatherable System Design Featured in WaterWorld Magazine - Discharger Aids Bio-cleanup Project To treat contaminated groundwater at a New Jersey site, XDD Environmental designed and built a system that discharges high volumes of sodium bicarbonate from bulk bags automatically. The system pumps water from the ground, adds a variety of amendments to it, and re-injects the treated water into a different area of the site. The treated water promotes the growth of naturally occurring bacteria in the soil, which break down the contaminants.
