This Christchurch ALGA branch event brings together three laboratory representatives to present a practical discussion on laboratory Quality Assurance and Quality Control (QA/QC) and how environmental data is generated, assessed, and reported.
The session will focus on the laboratory perspective of QA/QC for soil, groundwater, and surface water analyses, providing insight into how results are produced and what common qualifiers, flags, detection limits, recoveries, duplicates, and uncertainties actually mean in practice. Presenters will explain how laboratories apply QA/QC controls, how potential issues are identified, and what information can (and cannot) be inferred from standard laboratory reports.
Speakers will also discuss typical challenges associated with contaminated land samples, including matrix effects, sampling and preservation issues, and how improved communication between consultants and laboratories can help avoid misunderstandings or unnecessary re sampling. Common misconceptions seen by laboratories will be addressed, along with an overview of alternative analytical approaches that may be available for specific contaminants or project objectives.
Rather than promoting QA/QC as a checklist exercise, the session aims to improve shared understanding at the lab–consultant interface, helping attendees better interpret laboratory outputs, ask more informed questions, and use environmental data more effectively. This event will be of interest to consultants, regulators, and practitioners who regularly rely on laboratory data and want greater clarity around its strengths, limitations, and appropriate use.
