SESSION CHAIR & KEYNOTE - Getting It Straight: Defensible Data
Collecting Defendable Environmental Data: What Does That Mean?
There are many aspects to collecting defendable data including technical, regulatory and legal. The first question to ask is: Why are you collecting the data? Understanding the purpose of the data collection effort is the first step in identifying the proper framework(s) for collecting the data. Technical frameworks include industry best practices such as ASTM and ITRC guidance. Regulatory frameworks include a wide variety of federal, state and local laws and regulations, and associated guidance. The legal framework must consider appropriate technical and regulatory framework relevant to the legal issue, but data collection often must be performed to an even higher standard to withstand intense legal scrutiny. The human factor is probably the most important part of the equation. No matter how good the work planning, field staff must have the proper training and project background to understand not just the “What,” “Where” and “How” but the “Why” so they can properly adapt to observed conditions to collect defendable, high quality data.
