In Situ Remediation Monitoring Programs: Considerations and Design - On Demand Program

Location: On-Demand @ EPOC's LMS Site.


You must first register here (the main event page) before you can have access to the program on the LMS site.


  • Lucas Hellerich, PhD, PE, LEP, Woodard & Curran, Inc.
  • Zackary Smith, LEP, Verdantas

Continuing Education Credits:

The CT State Board of Examiners of Environmental Professionals (LEP Board) has approved this program as an on-demand distance learning course for 4.0 hours of continuing education credits (CTLEP-504 D). You cannot obtain CT continuing education credits if you have taken the previously offered live EPOC webinar offerings (11/9/20 or 4/16/21), or the MA LSPA webinar offering on 11/10/21 that was issued Course # CTLEP-551W, and claimed it to fulfill your CEC requirements. As posted on CT DEEP's websiteshould a distance learning course be an electronic conversion of a course previously offered as a webinar or in-person course, an LEP cannot take such distance learning course for credit if the LEP has taken the webinar or in-person course for credit unless two biennial periods have passed since the taking the classroom or field course. LEPs must complete an on-demand/distance learning course in its entirety to claim any credit whatsoever, partial credit will not be awarded.

About this On-Demand Course:

This program was previously offered as a live webinar on 4/16/21 and is a recording of that event. If you are taking this program for CT continuing education credits (CECs), you must watch the entire program video and will not have option of fast forwarding through any content. You may pause the video and return at any time to finish. After you complete the video, you will then be required to complete an Assessment of Learning test before your CEC form is issued. You must pass the Assessment of Learning test with a minimum score of 70% to complete the class and receive your continuing education credit form.


  • EPOC Members: $200

Course Description:

In situ remediation is used to treat numerous contaminants in soil and groundwater through the application of reagents and physio-chemical processes in the subsurface. The performance and effectiveness of in situ remediation technologies are assessed through monitoring of groundwater and other media. Often, monitoring programs are established based on existing well networks and industry rules of thumb. Development of monitoring programs needs to account for the type, scale, and longevity of the applied in situ remediation technology, as well as the conceptual site model. The objectives of this course are to review the effects that different in situ remediation technologies have on soil and groundwater and best practices for monitoring those effects.

The first part of this course will include a review of in situ remediation technologies and their physio-chemical effects on groundwater systems. The course will then present the concept of a zone of influence for in situ remediation, the influence of the conceptual site model on the zone of influence, and how groundwater geochemical conditions stabilize following an in situ remedy application. Then, design considerations for in situ remediation monitoring programs will be discussed. Several case studies will be presented to illustrate design concepts. Lastly, regulatory requirements for the monitoring of in situ remediation in Connecticut will be reviewed and related back to the design of monitoring programs.

Course participants will learn how to design monitoring programs for in situ remediation that provide an adequate level of information to understand the effectiveness of the remedy, while providing the ability to address uncertainties of the subsurface. They will learn about the different stages and objectives of monitoring. Further, they will gain an understanding of the range of biogeochemical and physical effects that can occur during implementation of an in situ remedy. Design concepts will be reviewed. Participants will be provided with a framework for selection of design parameters.

Course Agenda:

  • Introduction and course objectives
  • In situ remediation technologies and effects on groundwater systems
  • Zone of influence for in situ remediation and the conceptual site model
  • Potential issues that occur during in situ remediation
  • Design considerations for in situ remediation monitoring programs
  • Regulatory requirements for in situ remediation monitoring programs

Instructor's Bios:

Lucas Hellerich is Practice Leader of remediation engineering for Environmental Remediation Services at Woodard & Curran, with over 20 years of professional experience. He graduated from the University of Connecticut with a Bachelors degree in Civil Engineering, Masters degree in Environmental Engineering, and a Doctoral degree in Environmental Engineering. He is a Connecticut Licensed Environmental Professional and a licensed Professional Engineer in Connecticut, New Jersey, New York, and Rhode Island. He is an environmental engineer with experience in remedial process optimization, contaminated site assessment and remediation, exit strategy development, peer review, liability valuation, and achieving regulatory compliance. He provides technical leadership for and supports remediation projects throughout the United States. He has experience conducting treatability and pilot studies and implementing full-scale approaches for in situ remediation technologies, including enhanced aerobic and anaerobic bioremediation, chemical oxidation, chemical reduction, thermal remediation, sequestration, and combined remedies.

Zackary Smith is a Practice Leader at Verdantas for Environmental Assessment and Remediation. He is also a Connecticut Licensed Environmental Professional (LEP). Mr. Smith supports the technical and business aspects of complex environmental projects and works with project teams, clients, and regulators to develop investigation, remediation, and site closure strategies. Mr. Smith has presented at environmental and scientific conferences on topics related to hydrogeology, environmental site characterization, and remediation. He has also participated in several working groups and technical teams through regulatory and industry organizations. At the time the on-demand course was recorded, Mr. Smith was at Woodard & Curran.
