2.26 Field Analyses<br />

Field analysis procedures should be implemented in accordance with the manufacturer's instructions and<br />

SOPs. Field analyses may include testing for VOCs using PID/FID or gas chromatograph, metals using<br />

XRF, and immunoassay testing kits for hydrocarbons.<br />

2.27 Method Detection, Quantitation, and Reporting Limits<br />

The method detection limit (MDL) is the minimum concentration of a compound that can be measured<br />

within a given matrix with a 99 percent confidence that the concentration is greater than zero. The MDL<br />

is determined by the laboratory for each analytical method and compound. MDL studies should be<br />

conducted by the laboratory on an annual basis.<br />

The method quantitation limit (MQL) is an established concentration at five to ten times the MDL value<br />

for a specific analyte and accounts for sample matrix effects during analysis. Values reported below the<br />

MQL should be flagged as an estimated quantity. The laboratory is required to run a standard at the<br />

MQL to ensure the reporting level can be achieved.<br />

The method reporting limit (MRL) is a values below which the laboratory reports a result as nondetected.<br />

The MRL may be based on project-specific target levels, regulatory action levels, or instrument<br />

and method capability. The MRL is adjusted based on sample matrix and dilution effect. The MRL<br />

cannot be below the MQL.<br />
