How do we develop legally and scientifically defensible data?
The USEPAs Data Quality Objectives Process and the individual USEPA methods define the QA requirements and documentation for a laboratory to generate data of known quality. As you go through the DQO process, the data confidence and quality is defined and specific QA protocols are determined. Well construction methods such as direct push technology and groundwater purging/sampling methods must be understood to produce representative/reproducible data sets (14).
