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)
ZG The ICP or ICP-MS Serial Dilution was not used for data
val dat on because the sample concentration was less than
53'imes Ine MDL
N1 See Case Narrative
RA Relative Percent Difference (RPD) was not used for data
val dat on because the concentration of the duplicated
sample is too low for accurate evaluation (< 1 Ox MDL)
DJ Sample dilution required due to insufficient sample
RA Relative Percent Difference (RPD) was not used for data
validation because the concentration of the duplicated
sample is too low for accurate evaluation (< 10x MDL)
Z3 Sampie volume yielded a residue less than 2 5 mg
RA Reahve Percent Difference (RPD) was not used for data
validation oecause the concentration of the duplicated
