10:00 am to 6:00 pm Eastern *********************************************************************************

After participating in this course, you will have learned:

  • How to delineate the extent of PHC impact on soil and groundwater in accordance with Phase Two Environmental Site Assessment Regulation¬†
  • How to apply the efficient soil and groundwater sampling for PHCs
  • Remediation Techniques for soil impacted with PHCs
  • Remediation Techniques for groundwater impacted with PHCs
  • A brief overview of Risk Assessment of PHC impacted soil and groundwater
  • Risk Management Measures (RMMs) for a PHC impacted site as an alternative to Cleanup

Remediation of soil and groundwater impacted by PHCs involves several in situ or ex situ treatments comprising containment, separation and decomposition, which include biological, chemical, physical and thermal treatment methods.

Proper delineation of the soil and groundwater impact is the cornerstone for remediation meeting the regulatory guidelines, risk-based remediation and/or risk management. To select the best treatment option for remediation, it is important to understand the nature, composition, properties, type of environment, fate, transport and distribution of the pollutants, mechanism of degradation including chemical and biological decomposition. This two-day course provides practically applicable yet science-based instruction on delineation, remediation and risk management of soil and groundwater hydrocarbon contamination. Cost effective field techniques for investigating petroleum contamination will be reviewed in detail. Data interpretation and validation procedures will be presented. A case example will also be discussed.
