METHOD QUAL DESCRIPTION
L20770-01 WG372031 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.
WG371930 Nitrate/Nitrite as N,dissolved M353.2-Automated Cadmium H3 Sample was received and analyzed past holding time.
Reduction
M353.2-Automated Cadmium RA Relative Percent Difference(RPD)was not used for data
Reduction validation because the sample concentration is too low for
accurate evaluation(<10x MDL).
Nitrite as N,dissolved M353.2-Automated Cadmium H3 Sample was received and analyzed past holding time.
Reduction
M353.2-Automated Cadmium RA Relative Percent Difference(RPD)was not used for data
Reduction validation because the sample concentration is too low for
accurate evaluation(<10x MDL).
WG372655 Phosphorus,total M365.1-Auto Ascorbic Acid RA Relative Percent Difference(RPD)was not used for data
(digest) validation because the sample concentration is too low for
accurate evaluation(<10x MDL).
L20770-02 WG372031 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.
WG371930 Nitrate/Nitrite as N,dissolved M353.2-Automated Cadmium HE Analysis performed past holding time. Method holding time
Reduction 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&Conditions).
M353.2-Automated Cadmium RA Relative Percent Difference(RPD)was not used for data
Reduction validation because the sample concentration is too low for
accurate evaluation(<10x MDL).
Nitrite as N,dissolved M353.2-Automated Cadmium HE Analysis performed past holding time. Method holding time
Reduction is less than or equal to 7 days and sample was received

WG372655 Phosphorus,total M365.1-Auto Ascorbic Acid RA Relative Percent Difference(RPD)was not used for data
(digest) validation because the sample concentration is too low for
accurate evaluation(<10x MDL).
WG372145 Total Alkalinity SM2320B-Titration ZW Method deviation. The sample was centrifuged prior to
analysis due to high solid content.
