L42294-01 WG160043 Calcium, dissolved M200.7 ICP MA One spike recovery was outside of the method limits: the
tluplicate spike and the method control recoveries were
within the method limits.
WG160012 Iron, tlissolved M200.7 ICP BC Target analyte detected in calibration blank at or above
method reporting limit. Concentration found in the sample
was 20 times above the concentration found in the
calibration blank.
Manganese, dissolved M200.7 ICP M2 Matrix spike recovery was low, the method control sample
recovery was acceptable.
M200.7 ICP ZK Target analyte tletecled in the blank as a negative result al
or above the negative method limit (i. e. high negative bias).
Sample wncenlration is al a minimum ten times greater
. than positive method reporting limit.
WG161715 Mercury, dissolved M1631, Atomic Fluorescence H7 Sample analysis pertortned past holding time. See case
narrative.
L42294-02 WG160043 Calcium, dissolved M200.7 ICP MA One spike recovery was outside of the method limits; the
duplicate spike antl the melhotl control recoveries were
within the method Ilmlta.
WG160012 Iron, dissolved M200.7 ICP BC Target analyte detected in calibration blank at or above
method reporting limit. Concentration found in the sample
was 20 times above the concentration found in the
calibration blank.
Manganese, dissolved M200 7 ICP M2 Matrix spike recovery was low, the method control sample
recovery was acceptable.
M200 7 ICP ZK Target analy[e detected in the blank as a negative result at
or above the negative method limit (i.e. high negative bias).
Sample concentration is at a minimum ten times greater
than positive method reporting limit.
WGi61715 Mercury, dissolved M1631, Atomic Fluorescence Hi Sample analysis performed Oast holding time. See case
narrative.
L42294-03 WG160043 Calcium, dissolved M200.7 ICP MA One spike recovery was outside of the method limits; the
duplicate spike and the melhotl control recoveries were
within the melhotl limits.
WG160012 Manganese, dissolved M200.7 ICP M2 Matrix spike recovery was low, the method control sample
rewvery was acceptable.
M200.7 ICP ZK Target analyte detected in the blank as a negative result at
or above the negative melhotl limit (i.e. high negative bias).
Sample wncentration is at a minimum ten times greater
than positive method reporting limit.
WGi61715 Mercury, dissolved M1631, Atomic Fluorescence Hi Sample analysis performed past holding time. See case
narrative.
L42294-04 WG160043 Calcium, dissolved M200.7 ICP MA One spike rewvery was outside of the method limits; the
duplicat¢ spike and the method control recoveries were
within the method limits.
WG160012 Iron, dissolved M200.7 ICP BC Target analyte detected in calibration blank at or above
method reporting limit Concentration fountl in [he sample
- was 20 times above the wncentration fountl in the
calibration blank.
Manganese, dissolved M200.7 ICP M2 Matrix spike rewvery was low, the method control sample
recovery was acceptable.
M200.7 ICP ZK Target analyte detected in the blank as a negative result at
or above the negative method limit (i.e. high negative bias).
Sample concentration is at a minimum ten times greater
Than positive method reporting limit.
WG161716 Mercury, dissolved Mi631, Atomic Fluorescence H1 Sample analysis pertormetl past holding lime. See case
