**Note - For every course we have implemented live stream remote attendance options for those who prefer a no-contact alternative to in-person attendance.  You will need a computer and an internet connection.  We will follow the maximum in-person meeting size as per health authorities and if recommended we will only offer remote attendance.

If conditions permit, you are welcome to attend the course in-person, we likely will have between 5 to 10 in-person attendee's in a large room to provide safe spacing.  We also wipe every surface down and provide hand washing and disinfectant wipes as a courtesy.  If you would like more information or have any questions, please contact us via email or phone 425 270 3274.


In this course, attendees will learn the role of quality assurance and quality control in developing environmental programs for site investigations, remediation, and monitoring at contaminated sites. Participants will become comfortable with concepts, tools, and the basic statistical methods needed for designing and implementing a field program, and will gain knowledge regarding how to work with a laboratory to ensure the right chemical analyses are performed on the right samples. There will be empahsis on how to plan for and then evaluate data produced to achieve the greatest usability.

Upon completion of the course, attendees will come away with tools for deciding how to assess environmental laboratory data, how to maximize data defensibility, and when an independent data validator is needed. The extensive hands-on exercises include working through a Quality Assurance Project Plan and setting up Excel worksheets to perform efficient assessments for standard analytical data.


Intended Audience:

This course is intended for environmental professionals who need a good grounding in the concepts and framework of quality assurance for environmental data.
