Concentrations reported with a J flag in the Qual field are values below the reporting limit (RL) but greater than the established method detection limit (MDL). There is greater uncertainty associated with these results and data should be considered as estimated. These analytes are not routinely reviewed nor narrated below as to their potential for being laboratory artifacts.

Concentrations reported with an E flag in the Qual field are values that exceed the upper quantification range. There is greater uncertainty associated with these results and data should be considered as estimated.

Any comments or problems with the analytical events associated with this report are noted below.

Analytical Comments for METHOD ASTM-D240, SAMPLE 1009A00-001A: During the testing process it was determined that the sample was not compatible with the BTU instrumentation available at the laboratory. Unable to report data for this analysis.
