Field Groundwater Purging, Monitoring and Sampling
Apr 18 - 19, 2023 /
Course Code: 13-0409-ONL23
This course is held online over 2 days on the following schedule (All times in Eastern Time Zone):
9:30 am to 5:30 pm Eastern
After participating in this course, you will be able to:
- Select the most updated techniques and methods in collecting representative samples of groundwater that meet the required needs for your project.
- Examine procedures and steps to follow in planning a successful field groundwater sampling program.
- Apply progressive techniques for monitoring groundwater quality and groundwater levels for long-term data collection that can be used for Environmental climate change impact on water resources and drought conditions.
- Minimize bias in collecting high-quality data for a cost-effective project using QA/QC.
- Develop and implement a successful and affordable groundwater sampling program that meets the regulations and requirements recommended by international environmental organizations in Canada and U.S.
This training course discusses the comprehensive approach and cost-effective operation of a successful field groundwater monitoring and sampling program to collect representative groundwater samples.
The workshop will assist individuals in understanding the design principle, required personnel, equipment needed, field operation and procedures of monitoring and collecting groundwater samples for analysis and saving money for their project.

Sample Shipment and Handling
- Sample chain of custody (COC)
- Selecting shipment method
- Low-flow purging and sampling
- Low-flow vs traditional purging
- Advantages of low-flow sampling
- Low-flow sampling requirement for dedicated pumps
- Low-flow sampling requirement for portable pumps
- Post sampling documentation
- Collection of drinking water samples
- Video Presentation of low-flow purging and sampling groundwater
The students are divided into two or three groups (depending on the number of students) and assigned to practice a case study in order to be familiar with the steps such as calculating the volume of purged water from a well, water level measurement, monitoring the parameters of stabilization as well as other activities in the field.
The video presentation will be shown in the morning of the next day's Course followed by questions and answers.
