r r rD QUAL DESCRIPTION
L71828-01 NG538856 Chloride SM4500CI-E 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).
WG538066 Cyanide,total M335.4-Colorimetric w/ M2 Matrix spike recovery was low,the recovery of the
distillation associated control sample(LCS or LFB)was acceptable.
WG538959 Nitrate/Nitrite as N M353.2-H2SO4 preserved 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).
WG538176 Phosphorus,total M365.1-Auto Ascorbic Acid RA Relative Percent Difference(RPD)was not used for data
(digest) validation because the concentration of the duplicated
sample is too low for accurate evaluation(<10x MDL).
WG537858 Residue,Filterable(TDS)@180C SM2540C 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).
SM2540C Z3 Sample volume yielded a residue less than 2.5 mg
WG537892 Residue,Non-Filterable(TSS)@105C SM2540D 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).
SM2540D Z3 Sample volume yielded a residue less than 2.5 mg
WG538421 Sulfate D516-02/-07/-11- M1 Matrix spike recovery was high,the recovery of the
TURBIDIMETRIC associated control sample(LCS or LFB)was acceptable.
L71828-02 VVG538856 Chloride SM4500CI-E RA Relative Percent Difference(RPD)was not used for data
validation because the concentration of the duplicated

WG538959 Nitrate/Nitrite as N M353.2-H2SO4 preserved RA Relative Percent Difference(RPD)was not used for data
validation because the concentration of the duplicated
sample is too low for accurate evaluation(<1 Ox MDL).
