Golder Associates ACZ Project ID: L41229
L41229-05 JVG437911 Chloride M300 0-Ion Chromatography DC Sample required dilution Non-target analyte exceeded
calibration range
M300 0-Ion Chromatography H2 Initial analysis within holding time Reanalysis for the
required dilution was past holding time
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)
WG436377 Residue,Filterable(TDS)@180C SM2540C RO The duplicate originally assigned to this sample was not
used for precision assessment because residue density
exceeded the method limits Another duplicate in the batch
was used to assess precision Method required duplicate
frequency was not met
WG437312 Sodium,dissolved M200 7 ICP M3 The spike recovery value is unusable since the analyte
concentration in the sample is disproportionate to the spike
level The recovery of the associated control sample(LCS
or LFB)was acceptable
WG437911 Sulfate M300 0-Ion Chromatography H2 Initial analysis within holding time Reanalysis for the
required dilution was past holding time
WG436792 Total Alkalinity SM2320B-Titration 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)
L41229-06 VVG437911 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)
WG436440 Residue,Filterable(TDS)@180C SM2540C RO The duplicate originally assigned to this sample was not
