RE: Project DUK-HV1201 Client Project: J12120170

Dear Mr. Perkins,

On December 14, 2012, Brooks Rand Labs (BRL) received three (3) wastewater samples and 

three (3) associated field blanks. An aliquot was removed from each sample bottle and filtered 

into a separate container designed for dissolved mercury (Hg) analysis. The sample volume 

from the original container was logged-in for total Hg analysis. All samples were received, 

prepared, analyzed, and stored according to BRL SOPs and EPA methodology.

Data used for regulatory purposes has a 24 hour filtration holding time requirement. Nonregulatory purposed data has a 48 hour filtration holding time. The samples were received

outside of the 48 hour filtration requirement and the results were qualified H. 

The results were blank-corrected as described in the calculations section of the relevant SOP

and may have been evaluated using reporting limits that have been adjusted to account for 

sample aliquot size. Please refer to the Sample Results page for sample-specific MDLs, MRLs, 

and other details. 

The analysis of continuing calibration blanks CCB1, CCB3, and CCB6 were slightly elevated. 

These CCBs did not bracket the analysis of client samples however and no further corrective 

action was necessary. Aside from concentration qualifiers, all data was reported without further 

qualification and all associated quality control sample results met the acceptance criteria.

BRL, an accredited laboratory, certifies the reported results of all analyses for which BRL is 

NELAP accredited meet all NELAP requirements. For more details, see the Report Information

page of the report. 

Please feel free to contact me if you have any questions regarding this report.

Sincerely,

Field Quality Control Samples

Please be notified that certain EPA methods require the collection of field quality control samples of an appropriate type 

and frequency; failure to do so is considered a deviation from some methods and for compliance purposes should only be 

done with the approval of regulatory authorities. Please see the specific EPA methods for details regarding required field 

quality control samples.

Dear Mr. Perkins, 

Attached is the report associated with four (4) aqueous samples submitted for selenium 

speciation on December 13, 2012. The samples were received in a sealed cooler at -0.2°C on 

December 14, 2012. Selenium speciation analysis was performed via ion chromatography 

inductively coupled plasma dynamic reaction cell mass spectrometry (IC-ICP-DRC-MS). Any 

issues associated with the analysis are addressed in the following report. 

If you have any questions, please feel free to contact me at your convenience. 

 Sincerely,

Huntersville, NC 28078 

Project: Belews Creek (Flex Fuel) - WW (LIMS #J12120170) 

December 19, 2012 

1. Sample Reception 

Four (4) aqueous samples in 125mL HDPE bottles (provided by Applied Speciation and 

Consulting) were submitted for selenium speciation analysis on December 13, 2012. The 

samples were received on December 14, 2012 in a sealed container at -0.2°C. 

The samples were received in a laminar flow clean hood, void of trace metals contamination 

and ultra-violet radiation, and were designated discrete sample identifiers. An aliquot of 

each sample was filtered (0.45μm) and each filtrate was stored in a secure, monitored 

cryofreezer (maintained at a temperature of -80oC) until selenium speciation analysis could 

be performed via ion chromatography inductively coupled plasma dynamic reaction cell 

mass spectrometry (IC-ICP-DRC-MS). 

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. 

Selenium Speciation 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 an 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. 

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 

Page 23 of 30
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). 

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. 

Selenium Speciation Analysis by IC-ICP-DRC-MS Each sample for selenium speciation 

analysis was analyzed by ion chromatography inductively coupled plasma dynamic reaction 

cell mass spectrometry (IC-ICP-DRC-MS) on December 14, 2012. An aliquot of each

sample is injected onto an anion exchange column and mobilized by a basic (pH > 7) 

gradient. The eluting selenium species are then introduced into a radio frequency (RF) 

plasma where energy-transfer processes cause desolvation, atomization, and ionization. The 

ions are extracted from the plasma through a differentially-pumped vacuum interface and 

travel through a pressurized chamber (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. 

4. Analytical Issues 

The overall analyses went well and no significant analytical issues were encountered. All 

quality control parameters associated with the samples were within acceptance limits. 

The estimated method detection limits (eMDLs) for selenite, selenate, and selenocyanate are 

generated from replicate analyses of the lowest standard in the calibration curve. Not all 

selenium species are present in preparation blanks; therefore, eMDL calculations based on 

preparation blanks are artificially biased low. 

The eMDL for methylseleninic acid and selenomethionine is calculated from the average 

eMDL of selenite, selenate, and selenocyanate. The calibration does not contain 

methylseleninic acid or selenomethionine due to impurities in these standards which would 

bias the results for other selenium species.
