1. Sample Reception
Page 9 of 27
Four (4) aqueous samples were submitted for hexavalent chromium, selenium speciation,
arsenic speciation, iron speciation, and manganese speciation analyses on June 30, 2015.
The samples were received in acceptable condition on July 1, 2015 in a sealed container at a
temperature of 0.0°C.
All samples were received in a laminar flow clean hood, void of trace metals contamination
and ultra -violet radiation, and were designated discrete sample identifiers. An aliquot of
each sample submitted for hexavalent chromium analysis was decanted into a clean
polypropylene tube. All hexavalent chromium sample fractions were stored in a secure
refrigerator maintained at a temperature of 4°C, until the analyses could be performed.
An aliquot of each sample requiring selenium speciation evaluation was decanted into a clean
polypropylene tube and each filtrate was stored in a secure, monitored cryofreezer
(maintained at a temperature of -80°C) until selenium speciation analysis could be
performed.
An aliquot of each sample submitted for arsenic speciation analysis was decanted into a clean
polypropylene centrifuge tube; all filtrates and original bottles were then stored in a secure,
monitored refrigerator (maintained at a temperature of <6°C) until the analyses could be
performed.
The sample fractions requesting iron speciation analysis were stored in a secure, monitored
refrigerator (maintained at a temperature of <6°C) until the analyses could be performed.
An aliquot of each filtered sample submitted for manganese speciation analysis was decanted
into a polypropylene centrifuge tube for Mn(II) analysis. These fractions were stored in a
secure, monitored refrigerator (maintained at a temperature of <6°C) until the analyses could
be performed. Subsequently, the original bottles (filtered and unfiltered fractions) intended
for Mn speciation were preserved to pH < 2 with concentrated HNO3 and then stored in a

Page 10 of 27
secure polyethylene container, known to be free from trace metals contamination, until the
digestion could be performed.
2. Sample Preparation
All sample preparation is performed in laminar flow clean hoods known to be free from trace
metals contamination. All applied water for dilutions and sample preservatives are
monitored for contamination to account for any biases associated with the sample results.
Hexavalent Chromium Analysis by IC -ICP -DRC -MS Prior to analysis, an aliquot of each
sample was filtered with a syringe filter (0.45µm) and injected directly into a sealed
autosampler vial. No further sample preparation was performed as any chemical alteration of
a sample may shift the equilibrium of the system, resulting in changes in speciation ratios.
Selenium Speciation Analysis by IC -ICP -CRC -MS Prior to analysis, an aliquot of each
sample was filtered with a syringe filter (0.45µm) and injected directly into a sealed
autosampler vial. No further sample preparation was performed as any chemical alteration of
a sample may shift the equilibrium of the system, resulting in changes in speciation ratios.
Arsenic Speciation Analysis by IC -ICP -CRC -MS An aliquot of each sample was filtered
directly into a sealed autosampler vial. No further sample preparation was performed as a
buffered EDTA solution was provided by Brooks Rand Labs for field -preservation of the
submitted samples.
Iron Speciation Analysis by Spectrophotometry No sample preparation was required as a de-
gassed HCL solution was provided by Brooks Rand Labs for field -preservation of the
submitted samples.
Manganese Mn(LI) Analysis by IC -ICP -CRC -MS An aliquot of each sample was filtered
(0.45µm) directly into an autosampler vial for Mn(II) analysis. No additional sample
preparation was performed as any chemical alteration of the samples may shift the
equilibrium of the system resulting in changes in speciation ratios.
Manganese Mn(IV) Analysis by ICP-QQQ-MS Each filtered and unfiltered sample submitted
for Mn speciation analysis was preserved with 1% HNO3 (v/v) upon sample receipt. Each
sample fraction was then further digested on a hotblock apparatus with aliquots of 50%
HNO3 (v/v) and 50% HCl (v/v), in accordance with the digestion procedure specified in EPA
Method 200.8. All resulting sample digests were analyzed for total manganese via
inductively coupled plasma triple quadrupole mass spectrometry (ICP-QQQ-MS).
3. Sample Analysis
All sample analysis is preceded by a minimum of a five -point calibration curve spanning the
entire concentration range of interest. Calibration curves are performed at the beginning of
each analytical day. All calibration curves, associated with each species of interest, are
standardized by linear regression resulting in a response factor. All sample results are

Page 11 of 27
instrument blank corrected to account for any operational biases associated with the
analytical platform.
Prior to sample analysis, all calibration curves are verified using second source standards
which are identified as initial calibration verification standards (ICV).
Ongoing instrument performance is identified by the analysis of continuing calibration
verification standards (CCV) and continuing calibration blanks (CCB) at a minimum interval
of every ten analytical runs.
Hexavalent Chromium Analysis by IC -ICP -DRC -MS Each sample for hexavalent chromium
analysis was analyzed by ion chromatography inductively coupled plasma dynamic reaction
cell mass spectrometry (IC -ICP -DRC -MS) on July 14, 2015. An aliquot of each sample is
injected onto an anion exchange column and mobilized by a basic (pH > 7) gradient. The
eluting chromium species are then introduced into a radio frequency (RF) plasma where
energy -transfer processes cause desolvation, atomization, and ionization. The ions are
extracted from the plasma through a differentially -pumped vacuum interface and travel
through a pressurized chamber (DRC) containing a reaction gas which preferentially reacts
with interfering ions of the same target mass to charge ratios (m/z). A solid-state detector
detects ions transmitted through the mass analyzer and the resulting current is processed by a
data handling system.
Retention times for each eluting species are compared to known standards for species
identification.
Selenium Speciation Analvsis by IC -ICP -CRC -MS Each sample for selenium speciation
analysis was analyzed by ion chromatography inductively coupled plasma collision reaction
cell mass spectrometry (IC -ICP -CRC -MS) on July 14, 2015. An aliquot of each sample is
injected onto an anion exchange column and mobilized by a basic (pH > 7) gradient. The
eluting selenium species are then introduced into a radio frequency (RF) plasma where
energy -transfer processes cause desolvation, atomization, and ionization. The ions are
extracted from the plasma through a differentially -pumped vacuum interface and travel
through a pressurized chamber (CRC) containing a reaction gas which preferentially reacts
with interfering ions of the same target mass to charge ratios (m/z). A solid-state detector
detects ions transmitted through the mass analyzer and the resulting current is processed by a
data handling system.
Retention times for each eluting species are compared to known standards for species
identification.
Arsenic Speciation Analysis by IC -ICP -CRC -MS Each sample was analyzed for arsenic
speciation via ion chromatography inductively coupled plasma collision reaction cell mass
spectrometry (IC -ICP -CRC -MS) on July 9, 2015. Aliquots of each sample are injected onto
an anion exchange column and eluted isocratically. The eluting arsenic species are then
introduced into a radio frequency (RF) plasma where energy -transfer processes cause
desolvation, atomization, and ionization. The ions are extracted from the plasma through a

Page 12 of 27
differentially -pumped vacuum interface and travel through a pressurized chamber (CRC)
containing a specific collision gas. Polyatomic interferences, due to their inherently larger
size, collide more frequently with the collision gas and therefore may be separated from the
analyte of interest via kinetic energy discrimination (KED). A solid-state detector detects
ions transmitted through the mass analyzer on the basis of their mass -to -charge ratio (m/z),
and the resulting current is processed by a data handling system.
Retention times for each eluting species are compared to known standards for species
identification.
Iron Speciation Analysis by Spectrophotometry All samples submitted for Fe speciation
quantification were analyzed on July 1, 2015 and July 2, 2015, in accordance with the
scientifically accepted method outlined by:
Stookey, L.L., (1970). "Ferrozine - A new spectrophotometric reagent for iron",
Anal.Chem., 42:779-81.
Manganese Mn(II) Analysis by IC -ICP -CRC -MS All samples for Mn(II) analysis were
analyzed by ion chromatography inductively coupled plasma collision reaction cell mass
spectrometry (IC -ICP -CRC -MS) on July 10, 2015. Aliquots of each sample are injected onto
an anion exchange column and mobilized by an acidic (pH < 7) gradient. An ion pairing
agent provides a dynamic ion exchange mechanism for the cationic manganese species on the
chromatographic column. The differences in the affinity of manganese species towards the
ion pair agent and the column results in separation. The eluting selenium species are then
introduced into a radio frequency (RF) plasma where energy -transfer processes cause
desolvation, atomization, and ionization. The ions are extracted from the plasma through a
differentially -pumped vacuum interface and travel through a pressurized chamber (CRC)
containing a reaction gas which preferentially reacts with interfering ions of the same target
mass to charge ratios (m/z). A solid-state detector detects ions transmitted through the mass
analyzer and the resulting current is processed by a data handling system.
Retention times for each eluting species are compared to known standards for species
identification.
Manganese Mn(IV Analysis by ICP -000 -MS All samples submitted for Mn speciation
quantitation were analyzed by inductively coupled plasma triple quadrupole mass
spectrometry (ICP-QQQ-MS) on July 17, 2015. Aliquots of each sample digest are
introduced into a radio frequency (RF) plasma where energy -transfer processes cause
desolvation, atomization, and ionization. The ions are extracted from the plasma through a
differentially -pumped vacuum interface and travel through an initial quadrupole (Q1), which
filters the target masses prior to their entrance into a second chamber. The second chamber
contains specific reactive gasses or collision gasses that preferentially react either with
interfering ions of the same target mass to charge ratios (m/z) or with the target analyte,
producing an entirely different mass to charge ratio (m/z) which can then be differentiated
from the initial interferences. The ions then exit the collision/reaction cell into and additional
quadrupole (Q2). A solid-state detector detects ions transmitted through the mass analyzer,

Page 13 of 27
on the basis of their mass -to -charge ratio (m/z), and the resulting current is processed by a
data handling system.
4. Analytical Issues
No significant analytical issues were encountered. All quality control parameters associated
with the samples were within acceptance limits.
The Mn(II) result for the client sample, identified as MW -21D, was greater than the value of
the associated high calibration standard. A linear range verification standard was analyzed at
2000 µg/L. The Mn(II) recovery for the linear range verification standard was acceptable, at
103.8%, demonstrating that the linear range of the analytical platform extended to 2000 µg/L
for Mn(II). All reported Mn(II) results were less than 2000 µg/L with the dilutions at the
instrument factored in, and thus were within the linear range demonstrated by the linear
range verification standard. No corrective actions were necessary.
Total and dissolved Mn results for the client sample, identified as MW -21D, were greater
than the value of the associated high calibration standard. A linear range verification
standard was analyzed at 2000 µg/L. The manganese recovery for the linear range
verification standard was acceptable, at 96.9%, demonstrating that the linear range of the
analytical platform extended to 2000 µg/L for manganese. All reported total and dissolved
Mn results were less than 2000 µg/L with the dilutions at the instrument factored in, and thus
were within the linear range demonstrated by the linear range verification standard. No
corrective actions were necessary.
Mn(IV) is quantified by analyzing the water samples for total Mn and dissolved Mn. Mn(IV)
is operationally defined as the difference between the filtered and unfiltered total Mn
concentrations, since it is thermodynamically favored to be in the form of a precipitate.
The estimated method detection limit (eMDL) for hexavalent chromium is generated from
replicate analyses of the lowest standard in the calibration curve.
The eMDL values for selenite, selenate, and selenocyanate are generated from replicate
analyses of the lowest standard in the calibration curve. Not all selenium species are present
in preparation blanks; therefore, eMDL calculations based on preparation blanks are
artificially biased low.
The eMDL values for methylseleninic acid and selenomethionine are calculated from the
average eMDL of selenite, selenate, and selenocyanate. The calibration does not contain
methylseleninic acid or selenomethionine due to impurities in these standards which would
bias the results for other selenium species.
The eMDL values for arsenite, arsenate, and dimethylarsinic acid are generated using the
standard deviation of replicate analyses of the lowest standard in the calibration curve. The
eMDL for monomethylarsonic acid is calculated from the average eMDL of the three arsenic

Page 14 of 27
species contained in the calibration (i.e., arsenite, arsenate, and dimethylarsinic acid); the
calibration and CCVs do not contain monomethylarsonic acid due to impurities in this
standard which would bias the results for other arsenic species.
The Fe(II) conversion test for sample MW -22D did not meet the acceptance criteria. No
qualification of the data was applied.
The eMDL values for Fe(II) and total recoverable Fe were set at 5 based on the sensitivity of
the instrument.
The eMDL for Mn(II) has been generated from replicate analyses of the lowest standard in
the calibration curve.
The eMDL values for Mn(IV) been calculated using the standard deviation of the method
blanks prepared and analyzed concurrently with the submitted samples.
