Workshop SA2.

Successful remediation can’t be achieved without a reliable quality assurance program

Sunday, 8 September, 2019

Instructors: Kelly Perkins, Naji Akladiss


Understanding the quality of analytical data is critical for determining if the data is appropriate for its intended use. The data review training will be presented in a progression that will start with an introduction that provides the objectives of the training. We will discuss and define basic quality control procedures employed during field sampling and laboratory analysis. We will then present an effective tool developed to aid in performing a basic quality data review of environmental analytical laboratory data. The remainder of the training will include a “hands on” training session to apply the data review tool to an actual per- and polyfluoroalkyl substance (PFAS) environmental analytical laboratory report.

We will discuss why we must review analytical data and provide a brief history of data review activities in the United States. A graded approach to data review will be discussed and we will define basic data quality elements that should be included in the review process.

History of Data Review Activities
We will trace the history of data review activities since the late 1970’s and discuss the evolution of the review process. We will learn why it is important to review data and discuss the limitations of laboratory accreditation.

The Graded Approach to Data Review
The next discussion will expand on the previous topics and provide training in a graded or “tiered” approach to data review. We will delve into the components that should be included with the most basic data review. We will discuss data completeness, sample preservation and technical holding times, blanks, surrogates, laboratory control samples, matrix spike samples, sample duplicates and extracted internal standards for isotope dilution methods (PFAS!!!) We will then discuss data usability and how to determine if the data quality is sufficient for the intended use of the data.

“Hands on” Training
This training will use a data review checklist to evaluate the data quality of an “actual” PFAS environmental analytical data report. The training will be very “hands on”. We will break out into groups and use a variety of supplied materials to review an “actual” data report. Through this exercise, we will identify problems that often occur in the analytical laboratory and learn the effects these problems may have on the usability of the data. We will then use what we have learned to make a determination if the data quality is sufficient for the intended use.


Who should attend?

Environmental consultants, site owners, and environmental regulators involved with characterization and remediation at fractured rock sites will benefit from this course.
