accurate evaluation (< 1 Ox MDL).
WG321920 Selenium (1312)
M6020 ICP -MS
RA
Relative Percent Difference (RPD) was not used for data
validation because the sample concentration is too low for
accurate evaluation (< 1 Ox MDL).
WG321793 Silver (1312)
M6010B ICP
RA
Relative Percent Difference (RPD) was not used for data
validation because the sample concentration is too low for
accurate evaluation (< 1 Ox MDL).
Sodium (1312)
M60108 ICP
RA
Relative Percent Difference (RPD) was not used for data
validation because the sample concentration is too low for
accurate evaluation (< 1 Ox MDQ.
WG321920 Thallium (1312)
M6020 ICP -MS
RA
Relative Percent Difference (RPD) was not used for data
validation because the sample concentration is too low for
accurate evaluation (< 10x MDQ.
WG321793 Vanadium (1312)
M6010B ICP
RA
Relative Percent Difference (RPD) was not used for data
validation because the sample concentration is too low for
accurate evaluation (< 1 Ox MDL).
Zinc (1312)
M60106 ICP
RA
Relative Percent Difference (RPD) was not used for data
validation because the sample concentration is too low for
accurate evaluation (< 1 Ox MDQ.
WG321645 Sulfur Sulfate
M600/2- 78-054 3.2.4
RA
Relative Percent Difference (RPD) was not used for data
validation because the sample concentration is too low for
accurate evaluation (< 1 Ox MDL).
WG321896 Chlonde (1312 DI)
SM4500CI -E
HD
Analysis is outside the intended scope of the method,
which does not provide hold time information for soil
extracts. No hold time is observed for collection to
extraction. The referenced method hold time is observed
for extraction- to-analysis.
SM4500CI -E
M1
Matrix spike recovery was high, the recovery of the
associated control sample (LCS or LFB) was acceptable.
SM45000I -E
RA
Relative Percent Difference (RPD) was not used for data
validation because the sample concentration is too low for
accurate evaluation (< 10x MDQ.
WG321817 Sulfate (1312 DI)
D516 -02 - Turbidimetric
HD
Analysis is outside the intended scope of the method,
which does not provide hold time information for soil
extracts No hold time is observed for collection to
extraction. The referenced method hold time is observed
for extraction- to-analysis.
D516 -02 - Turbidimetnc
RA
Relative Percent Difference (RPD) was not used for data
validation because the sample concentration is too low for
accurate evaluation (< 10x MDL).
