Course Catalogue.

After participating in this course, you will be able to:

• Delineate the extent of PHC impact on soil and groundwater in accordance with Phase Two Environmental Site Assessment Regulation.
• Apply efficient soil and groundwater sampling techniques for PHCs.
• Implement remediation techniques for soil impacted by PHCs.
• Employ remediation techniques for groundwater affected by PHCs.
• Conduct a risk assessment of PHC-impacted soil and groundwater and apply risk management measures (RMMs) as an alternative to cleanup.

Description
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 pollutant’s degradation mechanism, 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.
