METHOD!ACZ ID WORKNUM PARAMETER QUAL DESCRIPTION
Toluene M8260C/D GC/MS RA Relative Percent Difference(RPD)was not used for data
validation because the concentration of the duplicated
sample is too low for accurate evaluation(<1 Ox MDL).
trans-1,2-Dichloroethene M8260C/D GC/MS M1 Matrix spike recovery was high,the recovery of the
associated control sample(LCS or LFB)was acceptable.
