Course Catalogue.

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

• Plan and implement a sampling program for the assessment of contaminated sites
• Apply the correct statistical sampling and analyses methodologies
• Prepare your sampling strategies and data collection methodologies
• Benefit from practical information that will save you time, effort and money

Description

There are thousands of contaminated sites across Canada with widely varying characteristics for geologic and hydrogeologic settings, contamination types, contamination medium and transport pathways. One of the first stages to assess any potentially contaminated site is to perform a site investigation and collect and analyze some samples. Sampling strategies differ based on the sampling objectives (e.g., site characterization, remediation verification, target criteria and standards, waste characterization, etc.), variability of contaminants in the media being sampled, knowledge of the distribution of hazardous substances on the property, and costs. This workshop provides an overview of sampling strategies, field investigation techniques, and data analysis methods for assessing contaminated sites.

Objectives

The main objective of this workshop is to introduce attendees to the guiding principles and existing methods for preparing a sampling plan, current sampling methods, and data analysis methods for interpreting the collected data in the context of Environmental Site Assessment.

The specific objectives are to provide the following:

• A general understanding of the framework for Environmental Site Assessment.
• Overview of the common contaminants in soil and water, their characteristics, and pathways.
• Review site investigation methods, soil and groundwater sampling, and analysis procedures.
• Overview of conceptual models for site assessment
• A detailed review of sampling strategies and interpretation of collected data
