DESCRIPTION

L75394-01 WG262719 Calcium, 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.
WG262835 Fluoride SM450OF-C M2 Matrix spike recovery was low, the recovery of the
associated control sample (LCS or LFB) was acceptable.
SM450OF-C RA Relative Percent Difference (RPD) was not used for data
validation because the sample concentration is too low for
accurate evaluation (< 10x MDL).
WG262627 Nitrate/Nitrite as N, dissolved 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 RA Relative Percent Difference (RPD) was not used for data
Reduction validation because the sample concentration is too low for
accurate evaluation (< IOx MDL).
WG262926 Nitrogen, ammonia M350.1 - Automated Phenate N1 See Case Narrative.
M350.1 - Automated Phenate RA Relative Percent Difference (RPD) was not used for data
validation because the sample concentration is too low for
accurate evaluation (< 10x MDL).
WG263030 Sulfate 375.4 - Turbidimetric 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.
375.4 - Turbidimetric RA Relative Percent Difference (RPD) was not used for data
validation because the sample concentration is too low for
accurate evaluation (< 10x MDL).
WG262734 Total Alkalinity SM2320B - Titration ZW Method deviation. The sample was centrifuged prior to
analysis due to high solid content
US394.02 WG262719 Calcium, 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 (I-CS
or LFB) was acceptable.
WG262835 Fluoride SM450OF-C M2 Matrix spike recovery was low, the recovery of the
associated control sample (LCS or LFB) was acceptable.
SM450OF-C RA Relative Percent Difference (RPD) was not used for data
validation because the sample concentration is too low for
accurate evaluation (< 10x MDL).
WG262627 Nitrate/Nitrite as N, dissolved 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 (< 1 Ox MDL).
Nitrite as N, dissolved 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 (< IOx MOL).
WG262926 Nitrogen, ammonia M350.1 - Automated Phenate NI See Case Narrative.
M350.1 - Automated Phenate RA Relative Percent Difference (RPD) was not used for data
validation because the sample concentration is too low for
accurate evaluation (< 10x MDL).
WG262803 Residue, Filterable (TDS) @180C SM2540C ZO Concentration is based on a final residue greater than 200
Mg.
WG263166 Sulfate 375.4 - Turbidimetric M2 Matrix spike recovery was low, the recovery of the
associated control sample (LCS or LFB) was acceptable.
WG262734 Total Alkalinity SM2320B - Titration ZW Method deviation. The sample was centrifuged prior to
analysis due to high solid content
