Golder Associates ACZ Project ID: L62895
METHODACZ ID WVORKNUM PARAMETER QUAL DESCRIPTION '
L62895-01 WG509956 Beryllium,dissolved M200.8 ICP-MS IA Internal standard recovery exceeded the acceptance limits.
Concentration of associated target analyte(s)in the '
sample is<MDL.
WG510206 Chloride M300.0-Ion Chromatography 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).
WG510118 Chromium,dissolved M200.8 ICP-MS DD Sample required dilution due to matrix color or odor. '
Copper,dissolved M200.8 ICP-MS DD Sample required dilution due to matrix color or odor.
WG509814 Cyanide,Free D6888-09/OIA-1677-09 DE Sample required dilution. See Case Narrative.
WG509974 Fluoride SM450OF-C DD Sample required dilution due to matrix color or odor. '
SM450OF-C MA Recovery for either the spike or spike duplicate was
outside of the acceptance limits;the RPD was within the
acceptance limits.
WG510118 Lead,dissolved M200.8 ICP-MS DD Sample required dilution due to matrix color or odor.
WG510086 Mercury,dissolved M245.1 CVAA MA Recovery for either the spike or spike duplicate was '
outside of the acceptance limits;the RPD was within the
acceptance limits.
WG510068 Nitrate/Nitrite as N,dissolved M353.2-Automated Cadmium HE Analysis performed past holding time. Method holding
Reduction time is less than or equal to 7 days and sample was ,
received with less than half of the holding time remaining
(refer to item C5 of ACZ's Terms 8 Conditions).
W G509809 Nitrite as N,dissolved M353.2-Automated Cadmium RA Relative Percent Difference(RPD)was not used for data
Reduction validation because the concentration of the duplicated '
sample is too low for accurate evaluation(<10x MDL).
W G510050 pH SM4500H+B ZW Method deviation. The sample was centrifuged prior to
analysis due to high solid content.
W G510226 Silver,dissolved M200.8 ICP-MS D1 Sample required dilution due to matrix.
M200.8 ICP-MS DD Sample required dilution due to matrix color or odor. '
WG510206 Sulfate M300.0-Ion Chromatography RA Relative Percent Difference(RPD)was not used for data
validation because the concentration of the duplicated
sample is too low for accurate evaluation(<1Ox MDL).
W G510050 Total Alkalinity SM2320B-Titration ZW Method deviation. The sample was centrifuged prior to '
analysis due to high solid content.
W G510118 Uranium,dissolved M200.8 ICP-MS DD Sample required dilution due to matrix color or odor.
