U -Indicates that the compound was analyzed for but not
detected. The detection limit for the sample (not the
method detection limit) is reported with U (e.g., l0u).
J Indicates an estimated value. This flag is used in cases
where a target analyte is detected at a level less than
the lower quantification level. If the limit of
quantification is l~mg/L and a concentration of 3mg/L is
calculated, it is reported as 3J.
NA =Not Applicable. NRl = Not Required.
NC -Not calculable, results below detection limit.
The method used for the analysis of petroleum hydrocarbons is EPA
Method 418.1 (USEPA 600/4-79-020). Solid samples are extracted
using Method 9071 (USEPA SW846) then analyzed by EPA Method 418.1.
The following is a summary of the QC results accompanying these
sample results and a description of any problems encountered during
their analysis:
* Blank was free of contamination.
" Blank spike recovery was inside laboratory control
limits.
" Matrix spike recoveries were within laboratory control
limits.
