EENG 8273 - Sampling Methods for Contaminated Sites

Environmental Engineering Part-time Studies Course

School of Construction and the Environment

Course Details

This course is the fourth of a five course series in the contaminated site technical studies. The field school involves four full days of hands-on sampling exercises giving the students an opportunity to apply the knowledge and skills from Contaminated Site Investigation Process: sampling strategies, design and implementation of sampling plans, and interpretation of results. The sampling exercises include: (1) soil sampling using a drill rig, backhoe, and hand augers; (2) ground water sampling by installation, development, and testing of monitoring wells; (3) overview of surface water and sediment sampling techniques; and (4) demonstration of geophysical investigation techniques. The focus of the course is on the role of the site investigator in the contaminated-site management process.

Learning Outcomes

Upon successful completion of the course, the student will be able to:

  • Watch the drilling of a borehole and obtaining of soil samples for soil chemical analysis.
    • Describe concerns associated with sample collection procedure and labelling, sample tool decontamination procedures.
    • Practice soil vapour screening as an aid to sample selection and core logging.
  • View the construction of a monitoring well after drilling a borehole.
    • Demonstrate the method to develop and purge a monitoring well.
    • Describe the methods and concerns in collecting water samples for a variety of chemical contaminants, and preservation techniques.
  • Operate under supervision a variety of organic, vapour analyzers for use in performing a soil gas survey.
    • Explain how to conduct a soil survey and collect vapor samples.
    • Discuss the problems or conditions that may affect the survey results.
  • Watch a utility location demonstration for a subsurface data collection.
    • Observe under supervision a variety of geophysical tools.
    • Discuss the problems or conditions that may affect the geophysical results.
  • Watch use of a backhoe for collecting soil samples.
    • Demonstrate the use of head space test to determine the presence of volatile organics.
    • Describe the correct safety procedures when working alongside excavating equipment.
  • Perform a hydraulic response test in a monitoring well to determine hydraulic conductivity.
    • Describe the procedure used for applying either the Bouwer and Rice method or the Hvorslev method.
    • Describe how to gather data using a data logger.
    • Solve for hydraulic conductivity using field data.
  • Conduct a water level survey to determine the water table gradient and direction of ground water flow
    • Use an electric water tape to measure water levels in a monitoring well.
    • Use a surveying level to determine relative borehole elevations.
    • Calculate ground water elevations and prepare a hydraulic gradient map.
    • Determine the direction of ground water flow.
  • Compile a written environment report for the methodology and observation sections of the report.
