Ms. Kendall,
Attached is the report associated with five (5) aqueous samples submitted for hexavalent
chromium, arsenic speciation, iron speciation, and manganese speciation analyses on June 16,
2015. The samples were received in a sealed cooler at 1.1 °C on June 17, 2015. Hexavalent
chromium analysis was performed by ion chromatography inductively coupled plasma dynamic
reaction cell mass spectrometry (IC-ICP-DRC-MS). Selenium speciation and arsenic speciation
analyses were performed via ion chromatography inductively coupled plasma collision reaction
cell mass spectrometry (IC-ICP-CRC-MS). All samples requesting iron speciation analysis were
analyzed by spectrophotometry. Mn (II) and arsenic speciation analyses were performed via IC-
ICP-CRC-MS. Mn(IV) analysis were performed via digestion and subsequent analysis by
inductively coupled plasma triple quadrupole mass spectrometry (ICP-QQQ-MS). Any issues
associated with the analyses are addressed in the following report.
If you have any questions, please feel free to contact me at your convenience.
Sincerely,

1. Sample Reception
Five (5) aqueous samples were submitted for hexavalent chromium, arsenic speciation, iron
speciation, and manganese speciation analyses on June 16, 2015. All samples were received
in acceptable condition on June 17, 2015 in a sealed container at 1.1 °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. Sample fractions
requesting hexavalent chromium, arsenic speciation, and iron speciation analyses were field
filtered by the client. Two containers were submitted for each client sample requesting
manganese speciation, one field filtered fraction and one unfiltered fraction. An aliquot of
each sample submitted for hexavalent chromium analysis was filtered 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 submitted for arsenic speciation analysis was filtered (0.45µm)
into a 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
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.
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(II 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
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).

Page 12 of 29
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 June 22, 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.
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 June 26, 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
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 June 17, 2015, and 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 June 29, 2015. Aliquots of each sample are injected
onto an anion exchange column and mobilized by an acidic (pH < 7) gradient. An ion

Page 13 of 29
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(IL) Analysis by ICP-QQQ-MS All samples submitted for Mn speciation
quantitation were analyzed by inductively coupled plasma triple quadrupole mass
spectrometry (ICP-QQQ-MS) on June 30, 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,
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 sample identified as ABMW-4 was initially analyzed on June 26, 2015 for arsenic
speciation analysis. The arsenite concentration exceeded the range of the calibration. The
sample was reanalyzed on July 14, 2015 which confirmed the initial result. Since all quality
control parameters were within acceptance limits and the arsenite concentrations were
confirmed by a higher dilution the original result has been reported.
Unknown arsenic species were present in various samples associated with the arsenic
speciation analysis resulting in late elution into following sample injections. The late eluting
peaks did not affect the target arsenic species; however, differentiation between late eluting
peaks and other unknown arsenic species for a given sample could not be accomplished.

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 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
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) result of sample ABMW-4 was slightly greater than the associated total
recoverable Fe result. However, the relative percent difference was 18% and meet the criteria
for duplicate precision. All iron reported should be considered to be in the Fe(II) form. The
F(III) result for sample ABMW-4 was reported as non -detectable at an eMDL of 5.0 µg/L.
The eMDL value for Fe(II) and total recoverable Fe was 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.
