This 2-day seminar provides sound scientific basis & practical instruction on assessment & remediation of subsurface hydrocarbon contamination. Cost effective field techniques for investigating petroleum contamination are reviewed in detail....

Course Outline

After participating in the seminar, you will be able to:

• Discover which investigation techniques to use for petroleum hydrocarbon contamination and 
• Know how much assessment is enough
• Develop a clear understanding of applicable remediation technologies,  and when to combine them for optimum remediation
• Use practical information from an internationally recognized environmental expert that will save you time, effort and money.


Petroleum hydrocarbon releases have impacted many sites including: upstream sites, service stations, refineries, airports, fire training facilities, military facilities, brownfield sites, and commercial buildings. Knowing how to effectively assess and remediate subsurface petroleum contamination is a requirement for many environmental professionals.

This two-day seminar provides sound scientific basis and practical instruction on assessment and remediation of subsurface hydrocarbon contamination. Cost effective field techniques for investigating petroleum contamination are reviewed in detail. Data interpretation and validation procedures are demonstrated and applied. Applicable remediation technologies are fully explained including appropriate applications, advantages and disadvantages.  The Alberta Environment and CCME Canada Wide Standards are presented and discussed.


To provide you with a comprehensive understanding of how to properly investigate and remediate historical and fresh petroleum releases.
This seminar lays the foundation for successfully implementing soil and groundwater sampling programs for petroleum hydrocarbons and provides the relevant information to assess and remediate the sites. The appropriate technologies for remediating LNAPL, VOCs, dissolved contaminants (groundwater), and adsorbed contaminants (soil) are discussed and the key performance, cost, and design parameters are presented for each technology.

Who Should Attend

Environmental personnel who are involved in investigating, remediating and/or managing petroleum contaminated sites. Entry level and experienced professionals will benefit from the experience and insight of the instructor developed over thirty years of professional experience.

Faculty: Dr. Nasrat Hijazi, TDA Associates

Here are some reviews of the training vendor.
The course was very well presented and the course instructor was absolutely amazing.
Reviewed by 2013
Our instructor, Stephen Lamming, was outstanding and a true expert in his field. He was able to complement the technical air monitoring information with practical real life examples which was highly beneficial. He is an excellent communicator and was highly interactive with the course attendees. This course was recommended to me because Stephen Lamming does an outstanding job. I was very impressed with this course and have subsequently recommended it to my colleagues.
