Newly released second edition book investigates the state of the science and future trends.

Two decades ago, contaminated groundwater supplies were addressed by containing football field-sized areas and spending years excavating, injecting molasses as a bio-agent, or pumping millions of gallons of water through a filter. It was costly, resource-consuming and slow.

Determined to find more effective methodologies, the late Dr. Suthan S. Suthersan, formerly chief technical officer at Arcadis, broke the mold on conventional approaches to soil and groundwater remediation in his 1996 book, Remediation Engineering. The groundbreaking first edition challenged accepted industry-wide paradigms and influenced regulatory trends by introducing highly efficient and cost-effective technologies.

Continuing to lead in the field he pioneered, Dr. Suthersan and Arcadis coauthors John Horst, PE; Matthew Schnobrich; Nicklaus Welty, PG, CPG; and Jeffrey McDonough, PE ― all globally recognized thought leaders in their fields ― introduce the comprehensive second edition Remediation Engineering: Design Concepts, published by CRC Press . This second volume discusses the influence of regulatory developments, technological advances, the merging of complementary disciplines, health and safety considerations, and emerging industry trends in the remediation industry.


Remediation Engineering: Design Concepts co-author, Nick Welty discusses his long-time interest in remediation engineering, beginning when he was just 10 years old.

A lot has changed in 20 years and current market demands call for diligent regulatory compliance in shorter time frames at reduced costs. Remediation Engineering: Design Concepts covers the entire spectrum of current technologies employed in the remediation industry and highlights two decades of differing waves of contaminants and emerging new contaminants (such as PFAS), demonstrating new ways in which practitioners approach and adapt to remediation engineering.

"I trust it will not only inspire and guide engineers, scientists, regulators, students, and researchers but also truly advance our shared mission of improving the quality of life — today, tomorrow, and long into the future."

- Joachim Ebert, Arcadis Chief Executive Officer


How have remediation solutions evolved? One key finding discusses how Arcadis experts have discovered that contaminants are at their greatest mass (90 percent) in just 10 percent of sub-surface water supply cross- sections. By pinpointing the most concentrated area of contaminants in a large underground plume early in the process, remediation engineers can attack the “mass flux” of contaminants with a more cost-effective, focused approach. The contaminants can be accessed, treated and brought to closure (not merely “contained”) without affecting a significant portion of the water supply.

Current and future issues and trends that will have major impacts on further evolution of our industry are also covered and include topics such as the influence of big data, large contaminated groundwater plumes, emerging contaminants and impacts on water supplies, impacts from unconventional energy exploration, and vapor intrusion.

This book explores how we can we learn from the past as we continue to evolve, leaving a lasting legacy that will improve quality of life for generations to come.
