What must final reports include regarding the data from XRF?

Final reports must include all raw data and lab results obtained from X-ray fluorescence (XRF) testing because these details provide a comprehensive record of the testing process and findings. In environmental assessments, having the complete dataset is crucial for transparency and credibility. It allows for thorough review and validation of the data, which is essential for stakeholders who may have to make decisions based on the findings. Including raw data and lab results ensures that the report does not only present conclusive findings but also enables interested parties to conduct further analysis if needed. This level of detail is vital for regulatory compliance and scientific rigor, setting a high standard for the reliability of assessments related to lead exposure and risk management.
