​Course # ​142
​Date ​February 6-8, 2013
​Location ​Denver, Colorado
​Instructors ​Patrick E. Haas and Todd H. Wiedemeier, PG
Level​ ​Intermediate; it is assumed you have some experience in remediation system design.
​CEUs ​2.1

Nonmember price​ ​$1,245


 

Course overview

Numerous low-cost technologies for remediating soil and groundwater contaminated with organic contaminants have been developed. This course provides you with practical, technically sound guidelines on how to select the right technology for a particular site, as well as how to properly design, install, and monitor that technology to meet site closure requirements.

Technologies covered in this course include natural attenuation, enhanced bioremediation, air sparging, and phytoremediation for remediation of contaminated groundwater, bioventing for remediation of contaminated soil, and bioslurping for removal of light non-aqueous phase liquids.

The successful implementation of any of these remedial technologies requires the collection of the appropriate site characterization data and detailed system design. You will be provided with critical information on how to conduct natural attenuation field sampling, as well as design, install, and operate effective remediation systems, and will leave the course armed with practical knowledge and tools.

The instructors for this three-day course were involved in the development of most of these remediation technologies and have experience in the evaluation and installation of all of them.

Learning objectives

In this course, you will:

  • Balance theory and application
  • Develop expertise on evaluating the significance of natural attenuation processes at groundwater-contaminated sites
  • Discover how to effectively analyze data to allow quantification of rates of contaminant transport and attenuation
  • Acquire the necessary theoretical background and skills to design and implement low-cost remediation systems
  • Learn “keep it simple” design and operation guidelines
  • Receive practical information on how to screen individual sites for technology applicability, perform streamlined pilot tests to confirm applicability and obtain critical design criteria, and implement expanded or full-scale remediation systems.
  • Interact with course instructors to answer critical questions such as:
    • Where can you apply this approach?
    • How well did it work?
    • What type of blower or pump can you use?
    • What were the operation and maintenance requirements?
    • What did the regulators think?
    • Was the site closed?

Who should attend?

  • Site owners
  • Remediation engineers
  • Environmental consultants
  • Regulatory personnel
  • University researchers
  • Graduate students.
