NR=analyte concentration in sample exceeds spike amount for soil matrix or exceeds 2x spike amount for water matnx or sample diluted due to high matrix or analyte content. %Recovery=100*(MS-Sample)I(Amount Spiked),RPD=100*(MS—MSD)I(MS+MSD)*2 "MS and/or MSD spike recoveries may not be near 100%or the RPDs near 0%if a)the sample is inhomogenous AND contains significant concentrations of analyte relative to the amount spiked or b)if that specific sample matrix interferes with spike recovery
