SUBJECT: Data Review Narrative for Total and Dissolv ed Metals Analyses for the Steam Electric

Study, Episode 6557

Under CSC Purchase Order 663127SSD, Agriculture & Priority Pollutant Lab, Inc. (APPL) submitted

data for the analysis of metals by EPA Method 200. 7. Five aqueous samples in this episode were

analyzed for total and dissolved metals. Because infl uent samples for this study were expected to be

highly variable in solids content, th e laboratory was directed to obtai n results for the solid phase if the

total solids of the original sample were greater or equal to 1%. However, because the total solids for the

FGD influent sample were < 1%, the sample was not phase separated.

Table 1 provides a list of samples, matrices, desc riptions, sampling dates, phases, and the required

analytical methods.

# These data have been reviewed in accordance with CS C’s Data Review Guideline, (February 2008), and

requirements included in Purchase Order 663127SSD. All data are of acceptable quality with the

qualifiers described below and detailed in the data review summary table (Table 2).

SUMMARY

All samples were successf ully analyzed within method-specified holding times, and method detection

limit (MDL) studies were successfully performed. All reported results were acquired under acceptable

instrument calibration. The few metals detected above the method detection limit in the preparation

blanks, initial calibration blanks, a nd continuing calibration blanks are discussed below. All ongoing

precision and recovery (OPR), post digestion spike, and serial dilution sample recoveries were within

criteria, demonstrating that laboratory performance for these analyses was acceptable, with the exception

of the issues described below and summarized in Ta ble 2. The MS/MSD analyses were performed on

samples 71520 and 71523.

# 2 

# DATA ISSUES

Method and Analytical Blanks

Metals were detected in associated preparation blan ks (PBs), initial calibration blanks (CCBs), and in the

continuing calibration blanks (CCBs) asso ciated with the samples in this episode at concentrations greater

than the respective MDLs. The da ta quality is affected as follows:

• Sample Results Less than Five Times Blank Results: When the sample result is less than five

times the blank result, there are no means by which to ascertain whether or not the presence of the

analyte may be attributed to contamination. Therefore, SCC recommends that the data be

reported in the database as a non-detect at the inst rument detection limit, adjusted for dilution.

The affected samples and analytes ar e as follows: 71529 Calcium-Total.

• Sample Results Greater than Five Times but Less than Ten Times Blank Results : CSC considers

these results to be of acceptable quality, but they may be maximum values. The result for total

calcium in sample 70628 falls under this categor y. The affected samples and analytes are as

follows: 71520 Cobalt-Dissolved, 71521 Alumi num-Dissolved and Arsenic-Dissolved, 71523

Arsenic-Dissolved, and 71525-Aluminum-Dissolved.

• Sample Results Greater than Ten Times Blank Results or Analyte Not Detected in Sample : CSC

does not consider the presence of the analyte in th e blank to adversely affect the data in cases

where the sample results are greater than ten times the associated blank results or where the

analyte is not detected in associated samples. Several samples fall into this category, and CSC

considers such data to be acceptable without qualification.

Matrix Performance

MS/MSD analyses were performed on samples 71520 (t otal and dissolved) and 71523 (total and

dissolved). The recoveries of several metals we re outside the 75% - 125% acceptance criteria in both

samples 71520 and 71523. All r ecoveries in the associated OPR were within the 80% - 100% OPR

recovery acceptance range, suggesting that the recovery issues in the MS/MSD are related to the sample

matrix, and not laboratory performance. The relative pe rcent differences (RPDs) for all of the analytes in

both MS/MSD pairs were less than 11% , indicating very good precision.

When the analyte recovery exceeds th e recovery criteria and the analyt e is detected in the associated

unspiked sample, the data are of acceptable quality, bu t CSC recommends that these results be considered

as maximum values. These instances are detailed in Table 2.

When the analyte recovery is below the recovery cr iteria and the analyte is de tected in the associated

unspiked sample, the data are of acceptable quality, bu t CSC recommends that these results be considered

as minimum values. These instances are also detailed in Table 2.

Due to the high concentrations of calcium and magnesium in samples 71520 and 71523, these metals

were not qualified based on MS/MSD recovery.

Electric Study, Episode 6557

OVERVIEW

Under CSC Purchase Orders 663048SSD and 6621000SSD, Frontier GeoSci ences, Inc. submitted data for

the analyses of trace metals for to tal and dissolved mercury (Hg) by Method 1631E, metals (antimony,

arsenic, cadmium, copper, chromium, lead, nickel, selen ium, silver, thallium, and zinc) by Method 1638,

metals (antimony, arsenic, barium , beryllium, boron, cadmium, calcium, chromium, cobalt, copper, iron,

lead, magnesium, manganese, nickel, selenium, silver, sodium, thallium, vanadium, and zinc) by Method

200.8, hexavalent chromium by Method 1636, and arsenic and selenium by hydride generation-Atomic

Fluorescence Spectrometry (HG-AFS). The specific analy ses for each sample are listed in Table 1. Data

review was performed on the submitted results from methods 1631, 1638, 200.8 , and 1636. At EPA’s

direction, the HG-AFS results are not included in this review.

Because influent samples for this study were expect ed to be highly variable in solids content, the

laboratory was directed to obtain results for the solid phase if the total solids of the original sample were

greater or equal to 1%. However, because the tota l solids for the FGD influent sample (71520) were <

1%, the solid phase was not calculated.

# These data have been reviewed in accordance with CS C’s Data Review Guideline, (February 2008), and

requirements included. All data are of acceptable qua lity with the qualifiers de scribed below and detailed

in the data review summary table (Table 2).

SUMMARY

All samples were successful ly analyzed within method-specified holding times, all reported results were

acquired under acceptable instrument calibrations, an d all required blank analyses were performed. The

few metals detected in the preparation and other bl ank analyses are discussed below. All Matrix Spike

and Matrix Spike Duplicate (MS/MSD) recoveries were within criteria for methods 1631 and 1636. All

ongoing precision and recovery (OPR) sample recove ries were within the laboratory’s criteria,

demonstrating that laboratory performance for these analyses was acceptable, with the exception of the

issues described below and summarized in Table 2.

DATA ISSUES

Method and Analytical Blanks

Metals were detected in associated preparation blan ks (PBs), initial calibration blanks (CCBs), continuing

calibration blanks (CCBs) and other bl anks associated with the samples in this episode at concentrations

greater than the respective method detection limits . The data quality is affected as follows:

# 3 

# • Sample Results Less than Five Times Blank Results: When the sample result is less than five

times the blank result, there are no means by which to ascertain whether or not the presence of the

analyte may be attributed to contamination. Therefore, SCC recommends that the data be

reported in the database as a non-detect at the instru ment detection limit, adjusted for dilution. As

listed in Table 2, zinc results in samples 71521, 71522, and 71523 are within this category.

• Sample Results Greater than Ten Times Blank Results or Analyte Not Detected in Sample : CSC

does not consider the presence of the analyte in th e blank to adversely affect the data in cases

where the sample results are greater than ten times the associated blank results or where the

analyte is not detected in associated samples. Several samples fall into this category, and CSC

considers such data to be acceptable without qualification.

Matrix Performance

Matrix Spike/Matrix Spike Duplicate (MS/MSD) an alyses using methods 1638 and 1631 (dissolved and

total) were performed on sample 71520. MS/MSD an alyses using methods 200.8 and 1636 (dissolved

and total) and method 1636 were performed on samp le 71523. The laboratory performed a method 1631

MS on the dissolved fraction of sample 71523, but w as unable to perform a MSD due to limited sample

volume. MS/MSD analyses using method 1631 (dissolved) was performed on sample 71524.

Although all method 1631 and 1636 MS/MSD recoveries were within criteria, recoveries of several

metals were outside the laboratory acceptance criteri a for methods 1638 and 200.8. In every instance

where the MS and/or MSD recoveries are outside of acceptance limits, the spike concentration was less

than two times the sample concentration, indicating the possibility of matrix interference. The data

quality is affected as follows, and any data qualification is summarized in Table 2.

• When the analyte recovery exceed s the recovery criteria and the analyte is detected in the

associated unspiked sample, the data are of accep table quality, but CSC recommends that these

results be considered as maximum values.

• When the analyte recovery is below the recovery criteria and the analyte is detected in the

associated unspiked sample, the data are of accep table quality, but CSC recommends that these

results be considered as minimum values.

• If the recovery of an analyte is low in the MS, and the recovery for the s analyte is high in the

MSD, or vice versa, the data for that analyte wh en detected in the associated unspiked sample are

qualified as estimated.

Due to the high concentrations of calcium and magnesium in samples 71520 and 71523, these metals

were not qualified based on MS/MSD recovery.

TECHNICAL NOTES

Method Modifications

To minimize the possible loss of volatile selenium during sample preparation, the laboratory used a

closed-vessel digestion in preparing the samples.

OPR Recovery Criteria

# 4 

# Method 200.8 includes acceptance criteria of 85-115% fo r the “laboratory fortified blank” (LFB). The

LFB is equivalent to the ongoing precision and r ecovery (OPR) sample described in Method 1638 and

other 1600-Series methods. Method 1638 includes OPR acceptance criteria that vary by analyte and are

generally wider than the range listed in Method 200.8.

Given the similarities between the two analytical me thods, the laboratory opted to apply the analytespecific OPR limits in Method 1638 to both procedur es, augmenting them with in-house limits for the

metals in Method 200.8 that are not in Method 1638.

In evaluating the OPR results, CSC used the limits from Method 1638 and the laboratory’s in-house limits

for the other metals. All of the OPR results were those acceptance criteria.

Preparation Blanks

The laboratory routinely prepares three preparation bl anks with every batch of samples and averages the

results for these blanks. While this approach is d escribed in EPA Method 1631 (for mercury), it is not

described in Method 1638. CSC evaluated the field sa mple results against each of the preparation blanks

separately (not against the mean result). Therefore, our evaluation of the blanks represents a worst-case

scenario for each analyte.

Sample Duplicates

The relative percent difference (RPD) between samp le 71523 (SP3D1 FGD Bio Effluent Day 1) and

sample 71525 (SP4D1 FGD Bio Effluent Day 1 Dupli cate) was greater than 20% for several analytes;

however, samples are not typically quali fied based on sample duplicate results.

Additional Analytes

Two additional analytes, arsenic and chromium, we re included for evaluation by Method 1638.

Minimum Levels

In order to alleviate matrix interference and to obt ain caused by high levels of dissolved solids, the

laboratory performed various dilutions on sever al samples on which Method 200.8 and 1638 were

performed. MLs are adjusted appropriately.

Field or Filtration Blanks

No analytes were detected in the field or filtrati on blanks above the minimum reporting level (ML) except

for total mercury in samples 71527 and 71528; howe ver, samples are not typically qualified based on

field blank results.
