Abstract
Thirty-one placer mine sites were visited by EPA and State personnel during August 1997 as the first
phase of a study of the occurrence of metals in surface water above and below mines, and in effluent.
Field measurements were made of temperature, pH, electrical conductivity and settleable solids.
One-time grab samples were collected for laboratory analysis of total suspended sediment, total
recoverable metals, dissolved metals and hardness. Metals included aluminum, antimony, arsenic,
cadmium, calcium, chromium, copper, lead, magnesium, mercury, nickel, selenium, silver, and zinc.
The results show that metals concentrations increased in effluent and mixing zone waters compared
to background streams for all placer mine sites visited. For some but not all metals, the physical
measure of turbidity was an effective indicator of total recoverable concentration at the time of the
1997 sampling. Of the physical measures of particulate material tested, turbidity was the only
measure with enough collected physical data to allow a comparison with chemical data. The results
of sampling to date would not be expected to necessarily be representative of other placer mining
areas or for other periods of time. The second phase of this study will examine temporal variations
at a few selected sites during 1998.
-------
I. Introduction
A. Background
In 1997, EPA began a two-year study of metals in placer mining areas of Alaska. This document
is a report of data collected during the first field season of the study.
B. Goal and Objectives
The goals of the project are to measure the concentrations of metals in surface water affected by
placer mines, and to determine whether there is a relationship between physical measures (turbidity,
settleable solids, total suspended solids) and chemical measures (total recoverable and dissolved
metals concentrations) for placer mining effluent in Alaska.
To meet the goal, the project objectives were to determine:
Concentrations of the following parameters of concern:
dissolved and total recoverable metals turbidity
total suspended solids settleable solids
pH hardness
temperature
during late summer at all locatable operating mines that were discharging effluent and most
operating mines that were not discharging.
Temporal variability of metals concentrations in effluent at a few representative sites during
year 2.
The "natural background" concentrations of the parameters of concern for representative
placer mining operations in mining districts in Alaska;
The concentrations of the parameters of concern immediately upstream of the mining
operations;
The concentrations of the parameters of concern downstream from the placer mining
operations.
The relationship between metals and total suspended solids, settleable solids or turbidity in
both the natural background conditions and discharges.
-------
II. Methods
A. Study Design
During 1997, 54 samples were collected from 31 placer mining operations. Appendix A contains
the Quality Assurance Project Plan for this work and Appendix B contains the field report.
If a mine was discharging waste water, EPA obtained four samples from the site, one sample from
each of the following areas:
1) upstream of any disturbance1 (i.e., "natural background"),
2) immediately upstream of the discharge2,
3) the effluent,
4) downstream of the point of mixing (determined visually).3
Turbidity, temperature, pH, electrical conductivity, and settleable solids were measured in the field.
Dissolved and total recoverable metals and total suspended solids analyses were analyzed at the EPA
Region 10 Manchester Laboratory. Dissolved metals samples were improperly sampled at mines
in Eastern Alaska and were therefore not used in this analysis.
B. Field Work
Two field teams, each having both EPA and Alaska Department of Environmental Conservation
personnel, sampled sites respectively in the east and west part of interior Alaska (Appendix B).
Samples were collected using a "clean hands" technique, labeled in the field, and shipped with a
chain of custody form to the Manchester Laboratory. Details of the sampling procedure are
described in the Quality Assurance Project Plan (Appendix A).
the purposes of this study, disturbance was meant to include any observable physical
alteration of the stream channel by other mining activities upstream of the sampled mine.
2If there were no anthropogenic disturbances upstream from the discharge, only one
upstream sample (the "natural background" sample) was taken.
3 Where the state of Alaska indicated the physical location of the edge of the mixing
zone, samples were taken at the edge of the mixing zone. Where the state indicated a dilution
factor, samples were taken of effluent only without taking a downstream sample. Where a mine
was not discharging, samples were only collected upstream of any disturbance and immediately
upstream from the site.
-------
C. Laboratory Methods
The analytical methods and sampling specifications are listed in Table 1 and described in the Quality
Assurance Plan (Appendix A).
III. Results.
A. Distribution of Sites
1. Location of Mines
Samples and field measurements were taken at 19 mine sites around the Fairbanks area in Eastern
Alaska and 12 mines in the McGrath and Nome areas in Western Alaska (Figure 1). Areas were
selected to maximize samples from operating mines that were discharging effluent and to represent
mining areas. All of the mines were operating and 9 were discharging. The Talkeetna area was
visited, but no operating mines were found. Global Positioning System (GPS) positions for sample
locations are presented in Table 2.
2. Location of Sites Above and Below Mines
Table 3a lists samples by stream, locality of mine and by the position of the sample site relative to
the mine. Samples upstream from an operating placer mine were collected from most of the visited
mine sites and are designated "AM" in Table 3 for "above mine." If an upstream sample had no
further upstream disturbance, it also functioned as background sample. If not, a separate background
sample was collected if possible and designated "B."
Most mines that were visited recycled their effluent. Some mines had a discharge whereby water
drained from settling ponds because more water entered the mine area than could be reused. If a
mine had an effluent discharge, additional samples were collected. At mines with a State calculated
mixing zone, a sample was collected at the end of the mixing zone and designated "MZ." Without
an approved mixing zone, a sample was collected of the effluent and designated "E" and just
upstream of the effluent designated "U" (see Figure 2).
B. Overview of Data
1. Mean Concentrations
The laboratory report of data is presented in Appendix C. Summary statistics of laboratory and field
data are listed in Table 4. Statistical functions include maximum and minimum values, geometric
-------
means and arithmetic means derived from the full data set in Table 3. The summary data are
grouped in Table 4 by measurement parameter and by sample location relative to the mines.
2. Estimation of Background
The mean values for total recoverable metals in background samples for all sites grouped together
were less than the means for groups of effluent and mixing zone samples (Table 4). For the six
discharging mine sites with background samples, including above mine samples assumed to
represent background, metals concentrations in the background were less than downstream samples
in most but not all cases (Table 3).
3. Comparison Upstream and Downstream of Mines
Maximum and mean values for effluent and mixing zone samples were generally higher than
above-mine and upstream (of effluent) samples for most metals (Table 4). Variability in above-mine
disturbances among mine sites would preclude the usefulness of further general statements based
on grouping of sample locations. Instead, data from each site are best viewed individually.
Total recoverable metals data for individual sites (Table 3) showed that effluent metals levels were
mostly higher than levels in samples upstream of the effluent, for example Prince Creek effluent
(Figure 3). Metals levels in three of the four mixing zone samples were similar or elevated
compared to samples collected above the mines for Bonanza, Kougarak and Boulder Creeks (Figures
4, 5, and 6). Metals levels for the mixing zone sample from Switch Creek were extremely elevated
for some metals (Figure 7).
4. Summary of Exceedances of Criteria
Aquatic water quality criteria for Alaska (18 AAC 70.020) were exceeded by metals samples
collected in this study (Table 3a). Thirty samples for total recoverable metals exceeded chronic
criterion for lead, nine samples exceeded the chronic criterion for mercury, and eight samples
exceeded the chronic criteria for silver and zinc. One sample exceeded the chronic criteria for nickel
and selenium. The highest exceedances were effluent or mixing zone samples.
Human health criteria for ingestion of water and organisms were exceeded by thirteen metal samples
(Table 3b). The exceedances were distributed among lead, mercury, nickel and selenium. The
highest exceedances for these metals were found in effluent.
-------
5. Comparison with Previous Studies
EPA collected stream water samples from placer mines in 1995 and 1996 (unpublished). A
summary of the range of reported total recoverable metals values is presented in Table 5. As another
comparison, Table 5 shows ranges developed from Gold-Mining Effects on Heavy Metals in
Streams, Circle Quadrangle, Alaska (LaPerriere, Wagener, BjerkJie, 1985). The maximum values
of the current study are higher than previous samples. These higher values reflect the high metals
levels of the effluent samples.
C. Relationship between Physical and Chemical Measures.
Physical measures consisted of field measurements of temperature, electrical conductivity, turbidity
and settleable solids, and laboratory analyses of total suspended solids (TSS) and electrical
conductivity. Chemical measures consisted of field measurements of pH and laboratory analyses
of total recoverable and dissolved metals.
A temporal analysis of the relationship between physical and chemical measures will be done after
collection of the second year of data during 1998. For the 1997 data which consist of grab samples
at one point in time, preliminary observations between physical measures and metal concentrations
can be made to aid in planning the 1998 effort.
Theoretically, three physical measures including sertleable solids, turbidity, and TSS, should be
related to suspended particulate material in the water column. One physical measure, electrical
conductivity, should be related to the ion content of the water column and hence in part to the
dissolved metal content.
In the discussion below, a comparison of the physical measures is made with the two types of metals
samples, filtered and unfiltered, in order to examine the relationships between physical and chemical
measures. The unfiltered metals samples represent metals in the combined dissolved and particulate
phases. The filtered samples represent metals largely in the dissolved phase. Therefore, the
difference in metals concentrations between the unfiltered and filtered samples should represent
mostly metals in the particulate phase.
1. Settleable Solids, Total Suspended Solids (TSS), and Turbidity
Settleable solids are determined by measuring the depth of sediment that settles from a sample of
the water column over a one-hour period. Settleable solids represent only the coarsest particulate
material in the water column because substantial fine particulates may remain suspended after an
hour of settling. Total suspended sediment is determined by a gravimetric measurement of filterable
material and therefore is a direct measure of the amount of particulates greater than the filter size,
0.45 ^m, in a sample of the water column. The finest-size particulates such as colloidal material may
10
-------
pass through the 0.45 ^m filter and not be included in a TSS measurement. Turbidity is determined
by a measurement of light scattered by particulate material in a sample of the water column.
Because light scatter is affected not just by the amount of particulate material, but also by density,
shape, and color, turbidity can be considered an indirect rather than direct measure of particulates.
Turbidity is especially sensitive to finer grained material.
Each of these measures is sensitive to somewhat different characteristics of suspended particulate
material. In practice, rough correlation is usually found between total suspended solids and turbidity.
Settleable solids, being a measure of only the coarsest fraction of water-borne material, may show
less correlation with turbidity and TSS when the predominant part of the suspended material is fine-
grained.
Seven of the mine sites sampled had detectable values for settleable solids. Inspection of Table 3
shows a limited correlation between settleable solids, turbidity and TSS wherein the site with the
highest value for settleable solids (4.5 ml/L at Gold Run) also had the highest turbidity (3744 NTU)
and TSS (2351 mg/L). The remaining five sites with detectable settleable solids from trace to 0.5
ml/L had turbidity values from 0.2 to 1606 ml/L, but the correlation is poor. Several sites with no
detectable settleable solids still had turbidity values well over 10 NTU to as high as 171 NTU, and
TSS to as high as 318 mg/L.
Samples for TSS were able to be collected from only about one third of the sites. Of those sampled,
TSS data appear to be roughly correlated with turbidity measurements. Turbidity measurements
were made in the field at all sites, providing the most complete measure of particulates in the water
column for this set of samples. Because of the completeness of the data, turbidity is used in the
discussion below as the primary particulate measure with which to compare metals concentration.
Discussion of a comparison of metals with TSS is not pursued in detail in this report because of
fewer TSS data. However, inspection of Table 3 shows that comparative relationships with TSS and
turbidity are similar.
2. Electrical Conductivity
Electrical conductivity was measured in the field at all sites, and therefore provides a complete data
set for a physical measure with which to compare dissolved metals concentrations.
3. Comparison of Physical Measures with Metal Concentrations
Total recoverable and dissolved metals concentrations were compared with each other and with
turbidity. Table 6 lists the linear correlation coefficients, r values, for the comparisons. Clearly no
physical measure of particulates correlates with dissolved concentrations for any metal. Electrical
conductivity on the other hand has a modest correlation with dissolved calcium which makes up a
major part of the cation content (Table 3). Conductivity has no clear correlation, however, with any
11
-------
of the minor or trace metals which comprise the toxic constituents (Table 6). Therefore the data for
this study indicate no physical measure provides a good indicator for dissolved toxic metals.
For total recoverable metals, turbidity shows a modest correlation (r greater than 0.9) with several
metals. Some of the correlations are not considered to be necessarily significant, however, because
of too few correlatable values above the detection limits. Including only those trace metals with
more than 20 values of useable data above the respective detection limits, aluminum, copper, lead,
and nickel show correlation of total recoverable concentrations with turbidity with r values of about
0.90-0.92. The correlation suggests that the greater portion of the total recoverable mass of these
four metals occurred as particulate material at the time of sampling. Figures 10 through 13 show
examples of the comparisons for these metals. For reference to other general water quality
parameters Figures 8-11 also show comparisons with temperature and pH. Each figure shows both
total and dissolved concentrations, respectively, as plus (+) and ex (x) symbols. An example of a
parameter which showed no correlation between total recoverable concentration and turbidity is
arsenic (Figure 12).
Comparison of settleable solids measurements with total recoverable metals shows that settleable
solids can be an indicator of some of the sites with the higher metals concentrations, but is not a
sensitive indicator for all the sites. Of nine sample sites (from seven mine sites) with detectable
settleable solids, eight had metals concentrations high enough to exceed chronic water quality
criteria. Among these is the site with the highest settleable solids value, and highest metals
concentrations. However, of 41 sample sites with no detectable settleable solids, 27 still had metals
concentrations high enough to exceed water quality criteria.
IV. Discussion and Conclusions
The 1997 data indicate that 34 sample sites exceeded aquatic chronic criteria for at least one metal.
Of the ten sample sites for either effluent or mixing zone water, eight were included in the group
with exceedances of aquatic criteria (Table 3 a). Nine sample sites exceeded human health criteria
for ingestion of water and organisms, of which five were from effluent or mixing zones (Table 3b).
The remaining sites with exceedances of aquatic criteria were distributed mostly among upstream
and above mine samples having some evidence of upstream disturbance.
The data show that for some but not all metals, the physical measure of turbidity was an effective
indicator of total recoverable concentration at the time of the 1997 sampling. The best correlations
between the physical and chemical measures occurred for aluminum, copper, lead, and nickel, and
zinc. The data indicate for some metals (especially the metalloids, arsenic and antimony) no
correlation existed. These results are consistent with the occurrence of some trace metals primarily
as adsorbed or coprecipitated phases in particulate material, whereas others, in this case the
metalloids, occur mainly in the dissolved phase. Conclusions on the form of the metals are apparent
from the data collected for these sites at one particular time, but would not necessarily be
representative of other sites or other time periods.
12
-------
Of the physical measures of particulate material tested, turbidity was the only measure with enough
collected physical data to allow a comparison with chemical data. With more completeness, total
suspended solids would probably also provide a general indication of adsorbed or coprecipitated
metals in the water column. Notwithstanding other particulate measures, turbidity would appear to
be an especially useful monitoring parameter for biological as well as chemical indication. For
example, other studies have shown turbidity to be perhaps the best measure of particulate-caused
effects on benthic biomass in streams (LaPerriere and Reynolds, 1997, p. 278).
The results of this study would not be expected to necessarily be representative of other placer
mining areas. For example, a placer mine operating in alluvial sediments that are much more
mineralized than those sites included in this study would be expected to have higher metals
concentrations relative to turbidity than found here. Furthermore, the first year of this study did not
include any evaluation of temporal changes because only data from single grab samples were used.
The form of metals could conceivably change through time because of changing environmental
conditions or processing characteristics of the mining operation. The second year of the study in
1998 is intended to examine temporal variations.

a - All total metals were collected in the same 1 quart cubitainer. Dissolved metals were
collected using a filtration apparatus consisting of a disposable filter/filter holder fitted to a
500 ml pre-cleaned cubitainer.
b - All water samples for metals analysis were acidified in the field with nitric acid to a pH
less than 2. The metals samples were iced during shipment. Dissolved metals samples were
filtered through 0.45 um filters prior to acidification to a pH less than 2 with nitric acid.
c - Hardness was calculated as the sum of the calcium and magnesium as measured by Method
200.7.
* Metals detection limits (except for calcium and magnesium) were set to the lowest level
aquatic life criteria based on a sample hardness of 25 mg/L.

* Depending on the actual number of samples shipped, there will be between six and seven total
metals data packages and six and seven dissolved metals data packages. Starting Monday,
September 22, a minimum of two packages are to be delivered to the EPA QADU each Monday.
The last data packages are to be received by Monday, October 20. The schedule of at least two
data packages per week (more some weeks so that all packages are received by October 20)
needs to be maintained so that data validation can start in time for the data assessment/analysis to
be completed in time. TSS analyses will be validated by the EPA Manchester laboratory. All
validated TSS data must be delivered to Joe Goulet by October 27, 1997.
All field reports will be completed within one month of sample collection. Laboratory results and
interpretation (if necessary) will be appended.
3 QA Objectives
3.1 Data Usage:
The data from the Summer of 1997 (broad sampling of all active sites and half of the
inactive sites) will be used to see if a relationship between metals and other general
parameters such as TSS and/or settleable solids and/or hardness can be established for the
placer mining operations in Alaska. If a relationship can be established, an extensive
second round of sampling will occur in the summer of 1998. The data from the extensive
round of sampling will be used to determine temporal trends in the relationship between
metals and other general parameters.

3.2 Monitoring network/sample collection design and rationale:
The sampling team will take chemical and physical measurements in August 1997, at
approximately 75 active mines in the Anchorage, Fairbanks, and Nome mining areas.
Remote mines on the Trinity Islands, Shumagan Islands and the lower Yukon River will
not be included in this survey. Where a mine is discharging waste water, four samples will
be taken, one from each of the following:
1) upstream of any disturbance (i.e., "natural background"),
2) immediately upstream of the discharge1,
3) the effluent,
4) downstream of the point of mixing (determined visually). If the state of Alaska
indicates the physical location of the edge of the mixing zone, EPA shall take samples at
the edge of the mixing zone. However, if the state indicates a dilution factor, EPA shall
sample the effluent and calculate the concentration after dilution (without taking a
downstream sample)
Where a mine is not discharging, samples will be collected upstream of any disturbance
and immediately upstream from the site.
EPA anticipates visiting approximately 40 to 50 mines that will have discharges. There are
likely to be another 50 that do not have a discharge. Samples will be collected at all mines
that have a discharge and approximately half those that don't, for a total of up to 250
sample locations (corresponding to 500 metals samples when total and dissolved metals
are counted).
Turbidity, temperature, pH, electrical conductivity, and settleable solids will be measured
in the field. AJ1 dissolved and total recoverable mercury and total suspended solids
analyses will be done by the EPA Region 10 Manchester Lab A private or State lab will
be procured by EPA to do the remaining total and dissolved metals analyses.
Containers collected from a given sampling point will be assigned a common EPA lab
number which will be marked on the container cap and on the side of the container. Each
sampling point will receive a separate EPA lab number Field duplicates and blanks will all
be assigned separate unique EPA lab numbers In addition, dissolved (filtered) metals
aliquots will be assigned a separate unique EPA lab number as most labs cannot use the
'If there are no disturbances upstream from the discharge, only one upstream sample (the
"natural background" sample) will be taken
-------
Alaska Placer Mining Survey QAPP
Revision 1, August 12, 1997 Page 4 of 14
same sample number to report two sets of similar data (in this case total vs. dissolved
metals).
The analytical parameter name or abbreviation will be marked on the cap and on the side
of the container. Abbreviations may include: TM for total metals; DM for dissolved
metals; Turb for turbidity; and Set Sol. for settleable solids.
Turbidity and settleable solids analysis will be performed in the field with a portable
turbidity meter (LaMotte Model 2008) and an Imhoff Cone, respectively.

a - All total metals will be collected in the same 1 quart cubitainer. For dissolved metals, a field
filtration procedure developed by Andy Hess at the EPA Manchester laboratory (consisting of
a disposable filter/two pieces of connective tubing and a 'tap' cap) will be used for dissolved
metals sample collection. See the section on sampling for further discussion of the sample
containers.
b - All water samples for metals analysis should be acidified, in the field when the sample is
ccJected, with nitric acid to a pH less than 2. Further, samples should be acidified for at least
16 hours prior to analysis. Icing of the metals samples is not required by CFR Part 136, Table
IB. However, if preservative cannot be immediately added to the samples, the samplers will be
icing the samples if they are to be preserved later in the day. Footnote 2 to Table IB allows for
preserving with ice 24 hour automatic composite samples when it is impossible to immediately
preserve each aliquot. The metals samples will be iced during shipment in the event TSS
aliquots are shipped in the same cooler. Dissolved metals samples will be filtered through a
0.45 um filter prior to acidification to a pH less than 2 with nitric acid. See the section on
sampling for a contingency discussion.
c - hardness will be measured as the sum of the calcium and magnesium as measured by
Method 200.7 (See notes in Table IB, 40 CFR Part 136).
* Metals detection limits (except for calcium and magnesium) have been set to the lowest level
aquatic life criteria based on a sample hardness of 25 mg/L.

4 1 Precision and Accuracy:
Precision: Precision will be evaluated by the relative percent difference (RPD) between
matrix spike/matrix spike duplicate samples or between laboratory duplicate samples (or
between field duplicate analyses for field measurements). The precision required for the
analyses involved with this project are in Table 1. The dispersion of these samples will
represent the various sampling areas identified in this plan (i.e., upstream, downstream and
effluent). In addition, the initial assessment of the field duplicates will be tied to those
areas (especially where divergent analyte concentration ranges are realized between
sub-groups of sample duplicates).
Accuracy: Accuracy will be evaluated by the use percent recovery (%R) of the target
analyte in spiked samples and/or laboratory control samples, where applicable. The
accuracy requirements are presented in Table 1.
4.2 Data Representativeness:
The samples will be grab samples. They do not represent temporal trends in the metals
concentrations around placer mining operations. This is an instantaneous representation
of water quality conditions around placer mining operations at the time of sampling.
4.3 Data Comparability:
Data will be reported according to established EPA Regional Laboratory protocols and to
the requirements specified in the contract laboratory statement of work (SOW) for metals
analysis (Appendix B).. Samples will be analyzed according to approved analytical
procedures. This set of data may be compared to other data There should not be a
comparability problem for TSS as the EPA regional lab has analyzed a lot of the past
samples. For the contract lab metals analyses, comparison to past data may not be
possible. However, future metals analyses will be conducted following the same SOW
(unless problems occur that require alteration of the SOW) This set of data will be
compared to the summer of 1998 sampling. Therefore, equivalent methods must be used
for both studies.
4.4 Data Completeness:
All samples collected are to be analyzed with appropriate supportive documentation Field
problems sometimes result in not all planned samples being collected. Laboratory
problems sometimes result in loss of samples or loss of data due to qualification. The
overall completeness goal for the summer of 1997 sampling is 80%. That is, a loss of
20% of the planned data should not fatally impact the data usability for the 1997 sampling.
For each mining operation, the field completeness goal for sample collection is 100% (that
-------
Alaska Placer Mining Survey QAPP Revision 1, August 12, 1997 Page 8 of 14
is, effluent should not be collected/submitted if an adequate background sample cannot be
obtained).
Sampling Procedures
5.1 Total Metals Sampling Procedures:
To the extent possible, the samplers will attempt to follow sampling procedures in Method
1669: Sampling Ambient Water for Trace Metals at EPA Water Quality Criteria Levels.
Project specific QA procedures are specified in this QAPP. The limited budget may
preclude the use of some sampling precautions outlined in this method. However, the
collection of field and equipment blanks should document whether or not the sample
collection methods have biased the sample results.
Each mining operation potentially will have up to four samples collected around it. The
sampling will start at the sampling point the farthest down stream and will proceed in
order up to the farthest up-stream sample point so that silt stirred up by wading into the
stream will not end up in the sample containers and positively bias the data.
Cubitainers should be held by hand when collecting samples. Samples should be taken
from a well mixed location by pointing the neck of the cubitainer upstream and
downwards - submerging the neck below the surface of the water. The bottom of the
container should be pushed down under the water as the container fills. If sampling
requires the sampler to enter the stream, the sampler should be downstream of the sample
location. Should it be necessary to use a clean unused cubitainer as a 'scoop' to obtain
sufficient sample, it should be thoroughly rinsed with stream water and used only for
sample taking purposes at one location. To prevent sample cross-contamination due to
'dirty hands', disposable talc free gloves will be used at each sample collection point prior
to collection of metals samples. In accordance with Method 1669, containers (collection
chambers for filtration apparatus) will be pre-rinsed at least once with the sample and then
submerged and filled with sample For un-filtered samples, the container cap will be
affixed while the container is still submerged (unless it is necessary to use successive
scoops of water from shallow streams to obtain sufficient volume).
5.2 Dissolved metals sampling procedures:
Prior to field work, the EPA samplers will make arrangements to visit the EPA laboratory
in Manchester, WA and will practice the filtration method thai will be used in the field.
They will also practice the clean hands/dirty hands sampling technique.
-------
Alaska Placer Mining Survey QAPP Revision 1, August 12, 1997 Page 9 of 14
5.2. / Filtration method:
A field filtration method developed at the EPA Manchester Laboratory is the
filtration method that will be used. This filtration procedure is simple to implement
but has not been fully tested for water quality criteria analyses. An initial analysis
of the filter cartridge and tubing has shown that metals (mercury was not analyzed)
were not present at levels above the required detection limits. Two clean
cubitainers are connected by two disposable short pieces of tubing with a
disposable 0.45 /^m accordion folded filter cartridge in between the pieces of
tubing. The filter cartridge in this apparatus is unlikely to clog if there is some
particulate in the samples as there is more surface area to the filter. The first
container is filled with unfiltered sample, a 'tap' cap is affixed to the filled
container and then connected via tubing to the filter cartridge (which is connected
by another piece of tubing to the receiving container) and then the water is forced
through the filter by squeezing the cubitainer. The filter cartridge, tubing, tap cap
and first collection container are all disposed of after collection is completed at one
location. No sample contact equipment is re-used at other sample locations.
The tubing will be pre-cut and if possible attached to the filter, then will be
individually double bagged in zip lock bags and will be shipped to the samplers in
the field (or will be taken as excess baggage by the samplers into the field).
Potential problem/resolution: it is slightly possible that the filter will clog up on
very turbid samples. It is anticipated that only effluent samples will be turbid and
most likely only a sub-set of the effluent samples will be turbid. The cost per
filtration apparatus is around $15. It will not be economically possible to use
multiple apparatus on samples. If this occurs, a clean cubitainer will be used to
collect an un-filtered, un-preserved (but iced) sample aliquot that will then be
shipped to the lab for lab filtration and preservation.
It is understood that lab filtration and preservation will result in data that is not
quite dissolved metals data. The results will be of unknown bias. This is because
some dissolved metals may adsorb to the walls of the container and will not be put
through the filtration process (low bias). However, some metals adhering to the
particulates in the sample may through bacterial action go into solution, possible
high bias in the dissolved metals data.
53 General sampling procedures:
All metals samples will be double bagged - the inner bag and container are only to be
touched by a clean hands sampler. All metals samples will be chemically preserved in a
-------
Alaska Placer Mining Survey QAPP Revision 1, August 12, 1997 Page 10 of 14
controlled manner. The two sampling teams will decide together, based on logistics, how
this will be achieved.
During preservation, the container should be kept within the bags - 'dirty hands' holding
open the outer bag while 'clean hands' touches the inner bag and container and preserves
the sample. 'Clean hands' will then re-cap each preserved sample and re-seal the inner bag
after which 'dirty hands' re-seals the outer bag and places the sample in a cooler for
shipment.
Sampling for analytes other than metals: the clean sampling techniques described above
are only necessary for the trace metals analyses. It is not necessary to double bag and
handle the TSS aliquots in this manner. The field crew may at their option take the same
precautions but should they find the precautions too onerous, they may opt to use normal
sampling procedures or chose not to take corrective action (re-gloving and/or re-
sampling) should the clean hands sampler accidentally 'contaminate' his gloves by
touching his clothes or a 'dirty' outer bag
Example scenario: at collection point one using normal sampling procedures, take field
measurements and the TSS sample. Then re-glove and follow clean sampling techniques
for metals collection. Proceed to the next sampling point, take field measurements and
TSS samples. Then re-glove and follow clean sampling techniques for metals collection.
All TSS and total metals sample containers will be supplied through the EPA Region 10
Lab. These will consist of quart/liter Cubitainers purchased as pre-cleaned containers.
The bottle supplier will be required to supply analytical data showing that the supply of
cubitainers, has been analyzed and shown to have no metals contamination above the
required detection limits before supplying the containers. Exception, the selenium
detection limit by the potential vendor (ESS) is 6 ug/L (1 ug/L above the required
detection limit). The EPA Region 10 Lab will provide each sampling team with four
individually double-bagged plastic rods (total of eight rods). The rods will be of suitable
diameter and length for the samplers to use them as a cubitainer expanding device
(cubitainers are supplied flattened and are difficult to open just with hands). The rods
should have smooth ends so that the cubitainers or sampler's hands will not be punctured.
Eight rods are needed in the event one or more is dropped and contaminated.
Each field crew will be responsible for double bagging individual un-used cubitainers for
use in the field for metals'sample collection Each evening, a sufficient supply of double
bagged containers needs to be placed in a 'clean' cooler for use the next day. During
initial bagging, both samplers will don clean gloves but only one person ('clean' hands)
will handle the containers, plastic rods and inner bags while the other person ('dirty'
hands) handles the outer bags and opening the outer containers of the large supply of
containers. When the cubitainer is placed in the inner bag, clean hands should then
remove a plastic rod from it's inner bag and use it to expand the cubitainer.
-------
Alaska Placer Mining Survey QAPP Revision 1, August 12, 1997 Page 11 of 14
Blank water will be suppled by the EPA or Alaska Department of Environmental
Conservation laboratory in pre-cleaned 1 gallon cubitainers. Before the water is used, a
blank sample from each batch of blank water will be composited from the 1 gallon
cubitainers and submitted blind to the contract laboratory to determine if analyte levels
are below the detection limits required for this project. Also, the composite blank water
will be used to rinse the plastic rods to document whether any contamination was
introduced to the samples by using the rods to expand the cubitainers. The rod rinse
water will be preserved and submitted blind to the lab for analysis.
A total of six transfer (total) blank and six equipment (filtered) blanks will be obtained and
sent blind to the lab. These blanks are expected to reflect the range of different field
conditions encountered during sampling. All > ansfer and filtration blanks are to be
collected and preserved using procedures as close to actual sampling as possible.
However, it will be unfeasible to exactly imitate stream sampling with blank water.
Following the method 1669 blank collection procedure (submersing the container in
standing blank water) is not representative of stream sampling. Therefore, a transfer
blank will be collected. The six transfer blanks does not include the one blank water
sample and one plastic rod rinse blank sample that will also be collected, preserved and
submitted for analysis (discussed in the previous paragraph).
Like the samples, the blank container must first be rinsed with blank water. The clean
hands sampler will hold the transfer blank bottle while the second sampler (taking care not
to handle the blank water supply around the opening) pours blank water into the blank
container. So long as the blank water supply is never contaminated by handling around
the opening, it can be used for all blanks.
If a second cubitainer has to be used as a scoop during sample collection (or is used as
part of the filtration step), the blank water will be used to rinse one clean cubitainer
(representing the scoop or supply reservoir for the filter), the blank scoop (connected to
the filter apparatus for equipment blans) will be used to rinse and then fill a second
cubitainer (representing the field or filtration blank) If two methods for collection
(intermediate collection device versus direct container collection) are used, the samplers
will collect a total of 8 total and 8 filtered blanks (proportioning the blanks according to
the approximate frequency of method use)
Each sampling team will be responsible for collecting half of the blanks. Additional blanks
may need to be added if field procedures are materially altered, field conditions warrant
more blanks (e.g. windy/dusty/and/or rainy conditions) or if the blank water supply is
changed (i.e. they run out and have to request more blank water).
Depending upon the relative concentrations of contaminants observed, the data for each
type of blank may be pooled for the purpose of discerning relative degrees of
-------
Alaska Placer Mining Survey QAPP Revision 1, August 12, 1997 Page 12 of 14
contamination (e.g., between sample teams, as sampling progresses, etc.) and/or all blank
results may be pooled to provide an overall contamination estimate for the entire sample
set.
Six TSS, six total metals, and six dissolved metals field duplicate samples will be collected
and submitted blind to the lab. With the first shipment and at an overall frequency of one
per forty field samples, a laboratory QC sample will be designated. For dissolved metals,
this means an extra sample will need to be collected if the special filtration apparatus is
used as the sample container on the filtration apparatus is only 500 mL. No extra volume
for lab QC should be required for TSS or total metals. Field analyses will be conducted in
duplicate at six sample locations Each field team will be responsible for collection of half
of the field QC samples.
The dispersion of the duplicate samples will represent the various sampling areas identified
in this plan (i.e., upstream, downstream and effluent). In addition, the initial assessment of
the field duplicates will be tied to those areas (especially where divergent analyte
concentration ranges are realized between sub-groups of sample duplicates).
6 Sample Custody Procedures
The samples will be in the custody of EPA personnel at all times. EPA Region 10 chain of
custody forms and procedures will be used. Each cooler of samples shipped to the
laboratory must stand alone on the custody documentation (i.e. only samples in the cooler
are to be on the custody form).
Minimally, every sample taken in the field will be labeled and accompanied by a chain of
custody form when shipped to the laboratory for analysis. EPA Region 10 laboratory
Analysis required forms for metals analyses will be completed (TSS can be hand-
written/requested on this form) These forms and/or labels will contain:
Sample identification number
Date and Time of sample collection
Sample location identification number and/or description
Sample matrix type
Signatures of samplers, sample handlers, and recorders
Type of analyses required
Number of containers representing the sample
Method of Shipment
Signatures and dates indicating the transfer of sample custody
7 Calibration Procedures and Preventive Maintenance:
For all chemical analyses, calibration procedures, frequency and preventive maintenance
shall be performed in accordance with the analytical methods cited and/or instrument
-------
Alaska Placer Mining Survey QAPP Revision 1, August 12, 1997 Page 13 of 14
manufacturer's recommendations. Additional quality control parameters for water
chemistry are given in Tables 1 and 2. The turbidity meter will be calibrated before each
measurement in the field.
8 Analytical Methods:
Where possible, monitoring/analysis shall be conducted in accordance with 40CFR part
136.3 approved NPDES analytical procedures found in the following references:
Standard Methods, 18th Edition, 1992
EPA Methods for the Analysis of Water and Waste Water, EPA EMSL-Cincinnati,
EPA-600/4-79-020, Revised March 1983 and 1979 where applicable.
Appendix C of part 136 (method 200.7)
Region 10 Alternate Test Procedure for method 200.8 (revision 5.4 found in
Methods for the Determination of Metals in Environmental Samples, Supplement
I, EPA, EMSL-Cincinnati, EPA/600/R-94/111, May 1994.
See Table 1 in the section on Sample Types for a list of specific method numbers. For
analyses to be conducted by the contract lab, see the attached statement of work
(Appendix B) and any pre-award alterations approved prior to award by EPA.
For analyses conducted by EPA and/or ESAT, standard reporting formats/deliverables/
approved method modifications routinely employed by the EPA Manchester laboratory are
acceptable so long as the DQO's specified in this QAPP are met. EPA Manchester
laboratory work assignment managers and/or the Deputy Project Officer will be
responsible for overseeing the ESAT contract costs/supplying technical direction to the
ESAT contractor in accordance with this QAPP. Just prior to field work, it was
anticipated that only EPA will support the TSS analyses to be conducted at the
Manchester Laboratory.
9 Documentation, Data Reduction, and Reporting
9.1 Documentation:
A field data form will be developed and copied onto 'write in the rain' paper. Field data
such as descriptive location information, global positioning satellite data, site observations
etc. will be recorded on field data forms for each mine location The field data form will
also assist the samplers in completing the chain of custody and analysis required form
documentation. The EPA field sample data sheet/chain of custody form and analysis
required forms will be used to document the sampling activities Optionally, dictation to a
-------
Alaska Placer Mining Survey QAPP Revision 1, August 12, 1997 Page 14 of 14
tape recorder and photos may be used to further document the sampling activities. There
is not a need for precise location description, however the samplers will be locating the
sample sites with GPS units.
9.2 Data Reduction and Reporting:
The contract and EPA Regional labs will be responsible for entry into the laboratory data
management system. Electronic deliverables are requested for this project. The EPA QA
office will be responsible for metals data validation. The EPA Manchester laboratory will
be responsible for TSS data validation. The validation of the data will be based on the
criteria outlined in the National Functional Guidelines for Inorganic Data Review (02/94)
and criteria outlined in this QAPP .
9.3 Data Assessment/Analysis:
Validated laboratory data will be provided to the Project Officer, Joe Goulet and David
Frank. Joe Goulet and David Frank are primarily responsible for analysis and
. interpretation of the data.
10 Performance; System A udils
Routine performance audits results for the Regional Lab are on record with the Regional
QA Officer. No system audit is planned for this investigation.
11 Corrective Action
Corrective action procedures that might be implemented from QA results or detection of
unacceptable data will be developed when and where required by the field operations
personnel.

Alaska Placer Mining Survey
Sampling Trip Report
Sample collection for the Alaska Placer Mining Survey occurred between August 19 and
31. Samples from the Fairbanks area were collected by Jim Corpuz (USEPA) and Paul Bateman
(ADEC). Samples from the McGrath, Nome and Talkeetna area were collected by Joe Goulet
(USEPA) and Ron McCallister (ADEC).
The sampling plan was followed with some exceptions. Dissolved oxygen was not
measured due to limitations on time available in the field and availability of field equipment.
The Fairbanks team acidified the dissolved metals sample before the sample was filtered.
Separate total suspended solids samples were not collected for samples at the beginning of the
trip.
A total of 31 mines were sampled resulting in 54 sample locations including blanks and
duplicate samples. The tables below summarizes the sample locations. Mines with an effluent
sample "E" or a mixing zone sample "MZ" are the sites that had a discharge.

-------
The field crew encountered a number of problems during the preparation and in the field,
which resulted in fewer locations being sampled than expected. The major problems were:
Weather - bad weather resulted in the loss of a day of travel to western Alaska: this problem was
compounded by the fact that EPA had to pay for the helicopters whether they were flying or not,
which used part of the helicopter budget for non-travel time
UPS strike - the UPS strike resulted in EPA not receiving some of the supplies in a timely
manner, resulting in the loss of two days
Operating/discharging mines - there were fewer mines operating and/or discharging than
anticipated
"Clean hands" technique - the use of the "clean hands" technique took much longer than
anticipated, which meant that fewer mines could be visited in one day

Sample Precision
Sample 97354850 was prepared in duplicate for Total Dissolved Solids. The relative
percent difference between the sample and it's duplicate was 40%. While the
significance of this result is minimal due to the low value upon which the calculation is
based, all sample results over the detection limit are qualified "J". The data user is
advised to consider the qualified data as estimates.

Alaska Placer Mining Survey - QC Narrative
TEC-311G, Page 2 of 5
October 24, 1997
1.0
Timeliness - Acceptable
The technical (40 CFR part 136) holding time from the date of
collection for mercury in water is 28 days. The holding time for the
remaining metals in water is 180 days. Collection of the water
samples began on 08/19/97. Mercury analyses were completed on
09/16/97. ICP-AES analyses were completed on 09/04/97. ICP-MS
analyses were completed on 9/12/97.
2.o Sample Preparation - Acceptable
Samples were prepared for mercury analyses on 09/09/97. Samples were
prepared for ICP-AES and ICP-MS analyses on 09/03/97. All sample
preparation was in accordance with the Manchester Laboratory
protocols. No qualification was made based on sample preparation.
3.0 Calibrations/Calibration Verifications - Acceptable
All samples were analyzed for mercury by CVAAS on 09/10/97, 09/12/97,
and 09/16/97. Initial calibrations included one blank and at least
four standards. The curves were linear with correlation coefficients
greater than 0.995. The calibration range was limited to 100 ng/L and
below in order to perform very low trace level analyses.
All samples were analyzed by ICP-AES on 09/04/97 (aluminum, calcium,
chromium, magnesium and zinc). The instrument was standardized
according to the analytical method using one blank and a single
calibration standard for each element.
All samples were analyzed by ICP-MS on 09/08/97 (antimony, arsenic,
cadmium, copper, lead, nickel, selenium, and silver). Some samples
were re-analyzed for arsenic on 09/12/97. Initial calibrations
included one blank and four standards. The curves were linear with
correlation coefficients greater than 0.995.
All calibrations were performed as required and met the acceptance
criteria; therefore, no qualification was made on this basis.
Calibration verification samples are required before and after sample
analysis and after every 10 samples during analysis. Mercury
recoveries must be within 80-120%. Other metal recoveries must be
within 90-110%.
All ICP-AES, ICP-MS and CVAAS (mercury) calibration verification
(initial and continuing) samples met the recovery criteria.
Calibration verification samples were analyzed after every ten samples
except for two sets of ICP-MS analyses that had calibration
verifications after 14 and 12 samples. No qualification was made
based on ICP-AES, ICP-MS, or CVAAS calibration verification.

TEC-311G,Page3of5
October 24, 1997
4.0 Laboratory Control Samples -
Laboratory Control samples are digested and analyzed along with the
samples to verify the efficiency of laboratory procedures. All
recoveries met the acceptance criteria for control samples. No
qualification was made on this basis.
Low Level Standards (LLS) are required to demonstrate a linear
calibration curve near the required detection limits (no acceptance
criteria but recovery of a standard near the detection limit is
expected). Low Level Standards were run at the required frequency.
Arsenic, silver and cadmium were not detected in either of the LLS
analyses on 09/08/97. The analyst suspected that cadmium and silver
were not added to the solution. The LLS solution was re-made the next
day and was ran during the 09/12/97 re-analysis of some of the samples
for arsenic. Silver and cadmium were detected in both LLS analyses on
09/12/97 (recoveries ranged from 73-124%). The detection limits
reported for silver and cadmium are acceptable. However, arsenic was
again not detected (0.1 ug/L instrumental "detection limit1, 0.15 ug/L
true value for the LLS) in either of the LLS analyses.
For ICP-MS, 1 ug/L (applied to arsenic, cadmium, lead, nickel, and
silver) and 5 ug/L (applied to antimony, copper, and selenium)
practical quantitation limit standards are run before every 100 ug/L
continuing calibration verification standard. All ICP-MS PQL
standards bracketing reported sample results met the 80-120%
laboratory acceptance criteria. Since the arsenic 1 ug/L PQL
standards were acceptably recovered while the 0.15 ug/L low level
arsenic standards were not detected, the actual instrumental detection
limit for arsenic is somewhere between 0.1 ug/L and 1 ug/L.
Therefore, detected arsenic results less than 1 ug/L are qualified
~J', estimated, while "undetected1 arsenic results are qualified ~UJ',
estimated detection limit.
5.0 Blanks - Acceptable for mercury
Procedural blanks were prepared with the samples to show potential
contamination from the digestion or analytical procedure. If an
analyte was found in the associated blank, the sample results were
qualified if the analyte concentration was less than five times the
analytical value in the blank.
All ICP-MS, ICP-AES, and CVAAS (mercury) procedural blank results met
the acceptance criteria.
All ICP-AES and CVAAS continuing calibration blanks (CCBs) surrounding
samples reported in this SDG were acceptable. An arsenic blank ran
towards the end of the ICP-MS analysis on 09/08/07 resulted in a
negative value (-0.117) with an absolute value greater than the
"detection limit1. Since all arsenic results less than 1.0 ug/L are
already being qualified as estimated, no further qualification was
made on this basis.

TEC-311G,Page4of5
October 24, 1997
6.0 ICP-AES Interference Check Sample - Acceptable
The interference check sample (ICS) is analyzed by ICP-AES to verify
interelement and background correction factors. Analysis is required
at the beginning and end of each sample analysis run and recoveries
must be between 80% and 120%. All ICS recoveries were within the
recovery criterion.
7.0 Duplicate Analysis - Acceptable
Duplicate analysis was done on sample 97354700. All results above the
laboratory's instrumental detection limit (IDL) were within the ±20%
Relative Percent Difference (RPD) (or ± Contract Required Detection
Limit (CRDL) for results < 5 times the CRDL) criteria.
8.0 Field Duplicate Analysis - Not Applicable
Field duplicate analysis for samples in this SDG was not indicated in
the field collection documentation.
9.0 Matrix Spike Analysis - Acceptable
Matrix spike sample analyses are done to provide information about the
effect of the sample matrix on digestion and measurement methods.
Matrix spike recovery must be within the limits of 75 - 125%.
Matrix spike analysis was done on sample 97354700. All matrix spike
recoveries were within the required QC limits.
10.0 Graphite Furnace Atomic Absorption Spec (GFAAS) QC - Not
Applicable.
GFAAS was not used for the analysis of these samples.
11.0 ICP-AES and ICP-MS Serial Dilution - Acceptable
Samples 97344550 (ICP-AES), 97344318 (all ICP-MS analytes), and
97344306 (ICP-MS arsenic only) were analyzed by serial dilution to
check for potential interferences. All analytes which exceeded the
minimum concentration criterion (50 times the IDL) agreed within 10%D.
12.0 Detection Limits -
Sample results which fall below the instrument detection limit (IDL)

13.0 Overall Assessment of the Data
This validation of the data is based on the criteria outlined in the
National Functional Guidelines for Inorganic Data Review (02/94).
During the ICP-MS matrix spike analysis, it was found that silver was
not spiked into the sample. The analyst decided to use the spike
sample prepared for ICP-AES. The silver recovery for this spike was
acceptable. However, the ICP-AES spike contains large amounts of all
target analytes as they are spiked at higher levels more appropriate
for ICP-AES analysis. Arsenic was not spiked in the ICP-AES spike
sample as it is usually only analyzed via ICP-MS.
Two samples (97344304 followed by 97344308) were analyzed immediately
after the high ICP spike sample. Since an instrument blank was not
run between the high spike and these two samples, there is no way to
know if detected sample results are actual sample results or carry
over from the high spike. Results for analytes with spike levels
greater than the routine 100 ug/L continuing calibration verification
standard were checked. Since copper, nickel and lead results in
sample 97344304 may be partially or totally due to carry over, these
results were qualified "J1, estimated. Arsenic results for both
samples are acceptable as arsenic was not in the ICP-AES spike. Lead
in sample 97344308 may also be partially or totally due to carry over,
so this result was qualified "J1, estimated. Copper and nickel
results in sample 97344308 were not qualified as they were more than
ten times the results for the sample (97344304) ran just before this
sample.
Approximately 3% of the data was qualified based on suspected carry
over or instrumental detection limit uncertainty.

Inorganic Data Review (02/94) qualifiers used when

1.0 Timeliness - Acceptable
The technical (40 CFR part 136) holding time from the date of collection for
mercury in water is 28 days. The holding time for the remaining metals in
water is 180 days. Collection of the water samples began on 08/27/97.
Mercury analyses were completed on 09/11/97. ICP-AES analyses were
completed on 09/08/97. ICP-MS analyses were completed on 09/10/97.
2.0 Sample Preparation-- Acceptable
Samples were prepared for mercury analyses on 09/08/97. Samples were
prepared for ICP-AES and ICP-MS analyses on 09/05/97. All sample
preparation was in accordance with the Manchester Laboratory protocols,
which do not require digestion for dissolved water samples that have low
turbidity. The turbidity of each sample was checked and was less than 1 NTU
(nephelometric turbidity unit), so the samples were transferred to
analytical containers and analyzed without digestion. The quality control
samples were made at the time the samples were transferred into analytical
containers. No qualification was made based on sample preparation.
3.0 Calibrations/Calibration Verifications - Acceptable
All samples were analyzed for mercury by CVAAS on 09/09/97, 09/10/97, and
09/11/97. Initial calibrations included one blank and at least four
standards. The curves were linear with correlation coefficients greater
than 0.995. The calibration range was limited to 100 ng/L and below in
order to perform very low trace level analyses.
All samples were analyzed by ICP-AES on 09/08/97 (aluminum, calcium,
chromium, magnesium and zinc). The instrument was standardized according to
the analytical method using one blank and a single calibration standard for
each element.
All samples were analyzed by ICP-MS on 09/10/97 (antimony, arsenic, cadmium,
copper, lead, nickel, selenium, and silver). Initial calibration included
one blank and four standards. The curve was linear with correlation
coefficients greater than 0.995.
All calibrations were performed as required and met the acceptance criteria;
therefore, no qualification was made on this basis.
Calibration verification samples are required before and after sample
analysis and after every 10 samples during analysis. Mercury recoveries
must be within 80-120%. Other metal recoveries must be within 90-110%.
All ICP-AES, ICP-MS and CVAAS (mercury) calibration verification (initial
and continuing) samples met the recovery criteria. Calibration verification
-------

samples were analyzed after every ten samples. No qualification was made
based on ICP-AES, ICP-MS, or CVAAS calibration verification.
4.0 Laboratory Control Samples -
Laboratory Control samples are analyzed along with the samples to verify the
efficiency of laboratory procedures. All recoveries met the acceptance
criteria for control samples. No qualification was made on this basis.
Low Level Standards (LLS) are required to demonstrate a linear calibration
curve near the required detection limits. Low Level Standards were run at
the required frequency. However, arsenic was not detected (0.1 ug/L
instrumental 'detection limit', 0.15 ug/L true value for the LLS) in any of
the LLS analyses.
For ICP-MS, 1 ug/L (applied to arsenic, cadmium, lead, nickel, and silver)
and 5 ug/L (applied to antimony, copper, and selenium) practical
quantitation limit standards are run before every 100 ug/L continuing
calibration verification standard. All ICP-MS PQL standards bracketing
reported sample results met the 80-120% laboratory acceptance criteria
except for one slightly high recovery for selenium. No selenium results
were qualified as sample results are not qualified based on PQL recovery
unless the recovery is very low or zero.
Since the arsenic 1 ug/L PQL standards were acceptably recovered while the
0.15 ug/L low level arsenic standards were not detected, the actual
instrumental detection limit for arsenic is somewhere between 0.1 ug/L and 1
ug/L. Therefore, detected arsenic results less than 1 ug/L are qualified
'J', estimated, while 'undetected' arsenicresults are qualified VUJ',
estimated detection limit.
5.0 Blanks - Acceptable
Procedural blanks were prepared with the samples to show potential
contamination from the digestion or analytical procedure. If an analyte was
found in the associated blank, the sample results were qualified if the
analyze concentration was less than five times the analytical value in the
blank.
All ICP-MS, ICP-AES, and CVAAS (mercury) procedural blank results met the
acceptance criteria.
All ICP-AES, ICP-MS, and CVAAS continuing calibration blanks (CCBs)
surrounding samples reported in this SDG were acceptable.
6.0 ICP-AES Interference Check Sample - Acceptable
The interference check sample (ICS) is analyzed by ICP-AES to verify
-------

TEC-311G, Page 4 of 5
November 10, 1997
interelement and background correction factors. Analysis is required at the
beginning and end of each sample analysis run and recoveries must be between
80% and 120%. All ICS recoveries were within the recovery criterion.
7.0 Duplicate Analysis - Acceptable
Duplicate analysis was done on sample 97354857. All results above the
laboratory's instrumental detection limit (IDL) were within the ±20%
Relative Percent Difference (RPD) (or ± Contract Required Detection Limit
(CRDL) for results < 5 times the CRDL) criteria.
8.0 Field Duplicate Analysis - Not Applicable
Field duplicate analysis for samples in this SDG was not indicated in the
field collection documentation.
9.0 Matrix Spike Analysis - Acceptable
Matrix spike sample analyses are done to 'jxtcvide information about the
effect of the sample matrix on digestion and measurement methods. Matrix
spike recovery must be within the limits of "75 - 125%.
Matrix spike analysis was done on sample 97354701. All matrix spike
recoveries were within the required QC limits.
10.0 Graphite Furnace Atomic Absorption Spec (GFAAS) QC - Not Applicable.
GFAAS was not used for the analysis of these samples.
11.0 ICP-AES and ICP-MS Serial Dilution - Acceptable
Samples 97354861 (ICP-AES) and 973-343-57 UCP-^S) \rere analyzed by serial
dilution to check for potential interferences. All analytes which exceeded
the minimum concentration criterion (5D times the IDLj agreed within 10%D.
12.0 Detection Limits -
Sample results which fall below the instrument detection limit (IDL) are
assigned the value of the instrument detection limit and the 'U' qualifier
is attached. The actual detection limit for arsenic did not meet the
requested detection limit. Data users are being consulted for corrective
action, if any.
13.0 Overall Assessment of the Data
This validation of the data is based on the criteria outlined in the
National Functional Guidelines for Inorganic Data Review (02/94).

It was brought to the reviewer's attention that some of the dissolved metals
samples were first preserved and then filtered in the field. Since the
samples were not preserved before fil.tration, the resulting data may not
really be dissolved metals data. The data may actually be closer to total
metals data. All un-detected data for the improperly preserved dissolved
samples are suitable for use without qualification as the method of
preservation should result in higher 'dissolved' metals data. All detected
results for the improperly preserved dissolved samples were qualified '#',
reported sample result may not represent the originally planned data. Data
users are cautioned that the data may actually be closer to total metals
data. Below is a list of improperly preserved dissolved sample numbers for
data reported in this set:
97354851 97354855 97354859 97354863 97354867
97354853 97354857 97354861 97354865 97354869
Approximately 7% of the data was qualified based on instrumental detection
limit uncertainty.
Below are the definitions for the National Functional Guidelines for
Inorganic Data Review (02/94) qualifiers used when validating/qualifying
data from Inorganic analysis.
DATA QUALIFIERS
U - The material was analyzed for, but was not detected above the
level of the associated value. The associated value is either
the sample quantitation limit or the sample detection limit.
J - The associated value is an estimated quantity.
R - The data are unusable. (Note: Analyze may or may not be

For ICP-MS, 1 ug/L (applied to arsenic, cadmium, lead, nickel, and
silver) and 5 ug/L (applied to antimony, copper, and selenium)
practical quantitation limit standards are run before every 100 ug/L
continuing calibration verification standard. All ICP-MS PQL
standards bracketing reported sample results met the 80-120%

Standards were run at the required frequency for ICP-AES and CVAAS. Low
Level Standards were not run during ICP-MS analyses for this batch of
samples.
For ICP-MS, 1 ug/L (applied to arsenic, cadmium, lead, nickel, and silver)
and 5 ug/L (applied to antimony, copper, and selenium) practical
quantitation limit standards are run before every 100 ug/L continuing
calibration verification standard. All ICP-MS PQL standards bracketing
reported sample results met the 80-120% laboratory acceptance criteria.
During ICP-MS analyses of the corresponding total metals samples for this
project, arsenic was not detected (0.1 ug/L instrumental 'detection limit',
0.15 ug/L true value for the LLS) in any of the LLS analyses. Recoveries
for other ICP-MS analytes when the LLS's were analyzed were acceptable.
Since the arsenic 1 ug/L PQL standards were acceptably recovered while the
0.15 ug/L low level arsenic standards were not detected, the actual
instrumental detection limit for arsenic is somewhere - between 0.1 ug/L and 1
ug/L. Therefore, detected arsenic results less than 1 ug/L are qualified
1J', estimated, while 'undetected' arsenic .results are qualified VUJ',
estimated detection limit.
5.0 Blanks - Acceptable
Procedural blanks were prepared with the samples to show potential
contamination from the digestion or analytical procedure. If an analyte was
found in the associated blank, the sample results were qualified if the
analyte concentration was less than five times the analytical value in the
blank.
All ICP-MS, ICP-AES, and CVAAS (mercury) procedural blank results met the
acceptance criteria.
All ICP-AES, ICP-MS, and CVAAS continuing calibration blanks (CCBs)
surrounding samples reported in this SDG were acceptable.

6.0 ICP-AES Interference Check Sample - Acceptable
The interference check sample (ICS) is analyzed by ICP-AES to verify
interelement and background correction factors. Analysis is required at the
beginning and end of each sample analysis run and recoveries must be between
80% and 120%. All ICS recoveries were within the recovery criterion.
7.0 Duplicate Analysis - Acceptable
Duplicate analysis was done on sample 97354701. All results above the
laboratory's instrumental detection limit (IDL) were within the ±20%
Relative Percent Difference (RPD) (or ± Contract Required Detection Limit
(CRDL) for results < 5 times the CRDL) criteria.
8.0 Field Duplicate Analysis - Not Applicable
Field duplicate analysis for samples in this SDG was not indicated in the
field collection documentation.
9.0 Matrix Spike Analysis - Acceptable
Matrix spike sample analyses are done to provide information about the
effect of the sample matrix on digestion and measurement methods. Matrix
spike recovery must be within the limits of 75 - 125%.
Matrix spike analysis was done on sample 97354701. All matrix spike
recoveries were within the required QC limits.
10.0 Graphite Furnace Atomic Absorption Spec (GFAAS) QC - Not Applicable.
GFAAS was not used for the analysis of these samples.
11.0 ICP-AES and ICP-MS Serial Dilution - Acceptable
Samples 97344309 (ICP-AES) and 97344319 (ICP-MS) were analyzed by serial
dilution to check for potential interferences. All analytes which exceeded
the minimum concentration criterion (50 times the IDL) agreed within 10%D.

12.0 Detection Limits -
Sample results which fall below the instrument detection limit (IDL) are
assigned the value of the instrument detection limit and the 'U' qualifier
is attached. The actual detection limit for arsenic did not meet the
requested detection limit. Data users are being consulted for corrective
action, if any.
13.0 Overall Assessment of the Data
This validation of the data is based on the criteria outlined in the
National Functional Guidelines for Inorganic Data Review (02/94).
It was brought to the reviewer's attention that some of the dissolved metals
samples were first preserved and then filtered in the field. Since the
samples were not preserved before filtration, the resulting data may not
really be dissolved metals data. The data may actually be closer to total
metals data. All un-detected data for the improperly preserved dissolved
samples are suitable for use without qualification as the method of
preservation should result in higher 'dissolved' metals data. All detected
results for the improperly preserved dissolved samples were qualified '#',
reported sample result may not represent the originally planned data. Data
users are cautioned that the data may actually be closer to total metals
data. Below is a list of improperly preserved dissolved sample numbers for
data reported in this set:
97344301
97344303
97344305
97344307
97344309
97344311
97344315
97344317
97344319
97344321
97344323
97344325
97344327
97344329
97344331
Approximately 4% of the data was qualified based on instrumental detection
limit uncertainty.
Below are the definitions for the National Functional Guidelines for
Inorganic Data Review (02/94) qualifiers used when validating/qualifying
data from Inorganic analysis.
DATA QUALIFIERS
U - The. material was analyzed for, but was not detected above the
level of the associated value. The associated value is either
the sample quantitation limit or the sample detection limit.
J
R
The associated value is an estimated quantity.
The data are unusable. (Note: Analyte may or may not be
present.)
-------

TEC-311G, Page 6 of 6
November 10, 1997
UJ - The material was analyzed for, but was not detected. The
associated value is an estimate and may be inaccurate or
imprecise.
Below is the definition of a special qualifier applied to some of the data:
DATA USE QUALIFIER
# The reported sample result may not represent the originally planned data.
Even though all analytical QA/QC requirements were met, information that
affects the intended use of the data was supplied to the data validator
prior to release of the data. See the QA memo attached to the reported data
for specific information.
