METHOD QUAL DESCRIPTION
RA Relative Percent Difference (RPD) was not used for data
validation because the sample concentration is too low for
accurate evaluation (< 10x MDL).
M2 Matrix spike recovery was low, the recovery of the
associated control sample (LCS or LFB) was acceptable.
325.2 / SM4500CI -E RA Relative Percent Difference (RPD) was not used for data
validation because the sample concentration is too low for
accurate evaluation (< 10x MDL).
WG241669 Coliforms, fecal SM9222D - Membrane Filter HE Analysis performed past holding time. Method holding 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 & Conditions).
WG241971 Fluoride SM4500F -C RA Relative Percent Difference (RPD) was not used for data
validation because the sample concentration is too low for
accurate evaluation (< 10x MDL).
WG241702 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 (< 10x MDL).
WG242032 Nitrogen, ammonia 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).
WG242149 Sulfate 375.4 - Turbidimetric M4 The spiked sample required a dilution such that the spike
recovery calculation does not provide useful information.
The recovery of the associated control sample (LCS or
LFB) was acceptable.
375.4 - Turbidimetric RD For a solid matrix, the duplicate RPD (spike or matrix)
exceeded the control limit, which is attributable to the non -
homogeneity of the sample.
WG241741 Total Alkalinity SM2320B - Titration B4 Target analyte detected in blank at or above the
acceptance criteria.
L68214 -03 WG242095 Acidity as CaCO3 SM2310B - Titration RA Relative Percent Difference (RPD) was not used for data
validation because the sample concentration is too low for
accurate evaluation (< 10x MDL).
WG242149 Chloride 325.2 / SM4500CI -E M2 Matrix spike recovery was low, the recovery of the
associated control sample (LCS or LFB) was acceptable.
325.2 / SM4500C1 -E RA Relative Percent Difference (RPD) was not used for data
validation because the sample concentration is too low for
accurate evaluation (< 10x MDL).
WG241971 Fluoride SM4500F -C RA Relative Percent Difference (RPD) was not used for data
validation because the sample concentration is too low for
accurate evaluation (< 10x MDL).
