<br /> Notes
<br /> I-Base PQLs(reporting limits)are listed for USEPA methods by Eurafins Air Toxics.The pressurization step performed by the laboratory at the time of receipt dilutes the sample and results in an increase
<br /> in the reporting limit. The actual reporting limit is calculated by multiplying the base reporting limit by the pressurization dilution factor,which is the ratio of the final canister pressure to the receipt
<br /> sample pressure.
<br /> 2-An attenuation factor of 0.03 was used to calculate the screening level
<br /> 3-The lowest of the USEPA RSL or DTSC Modified SL,or other as noted.
