ABSTRACT 

Following an open meeting entitled “Hydrocarbon Chemistry QA/QC” at the 2014 Gulf of Mexico Oil 

Spill and Ecosystem Science Conference in Mobile, Alabama, the Gulf of Mexico Research Initiative 

(GoMRI) initiated the Hydrocarbon Intercalibration Experiment (HIE) [1]. The goal of this effort was to 

address the importance of laboratory quality assurance/quality control (QA/QC) practices and to promote 

participation in quality assurance programs for hydrocarbon compounds. 

Over thirty laboratories expressed interest in participation in the Hydrocarbon Intercalibration 

Experiment. These laboratories were supplied with two petroleum crude oil samples provided by the 

National Institute of Standards and Technology (NIST): Standard Reference Material (SRM) 2779 Gulf 

of Mexico Crude Oil [2], and candidate SRM 2777 Weathered Gulf of Mexico Oil. SRM 2779 was 

prepared from neat oil collected directly from the leaking Macondo well during the 2010 Deepwater 

Horizon oil spill event, and candidate SRM 2777 is a field-weathered residue of the Macondo well oil 

dissolved in toluene. 

Twenty laboratories submitted results on traditional analytes (that included saturated hydrocarbons, 

aromatic hydrocarbons, and biomarkers) measured by gas chromatography coupled with mass 

spectrometry or flame ionization detection. The results for select hydrocarbons, aromatic hydrocarbons, 

and biomarkers from this intercomparison exercise are reported along with a summary of the analytical 

methods used. 

INTRODUCTION 

On the afternoon of January 26, 2014, the Gulf of Mexico Research Initiative (GoMRI) held a meeting 

entitled “Hydrocarbon Chemistry QA/QC” at the Gulf of Mexico Oil Spill and Ecosystem Science 

Conference in Mobile, Alabama. The goals of the meeting were to discuss the current state of knowledge 

on the analysis of oil and oil residues in water, sediment, soil, and tissue and to elucidate best principles 

for assessing and confirming high-quality and reproducible results. Of particular interest were refining 

and improving current methodologies, increasing awareness of new techniques, and expanding target 

analytes in native oils and weathering products following acute and chronic releases of oil and its refined 

products to the marine environment. 

The meeting was attended by experts in various subfields of oceanography and chemistry as well as those 

new to or interested in the analytical chemistry of oil spills [1]. Several researchers and GoMRI Research 

Board members made presentations, with subsequent discussion amongst the audience and presenters. 

The presentations are available at http://gulfresearchinitiative.org/hydrocarbon-intercalibrationexperiment/. 

After discussions with members of the community, the GoMRI board concluded that an intercomparison 

study would be timely and fruitful. Intercomparison studies are an excellent tool for assessing the 

comparability of analytical measurements. In addition, they provide an opportunity for researchers to 

compare their methods and approaches as well as to report and increase awareness on novel or typically 

untargeted analytes that may eventually become more standard. Lastly, they provide an opportunity for 

new researchers to understand and appreciate the demands and rigor needed to contribute positively to the 

field via a rigorous quality control and quality assurance plan.

In cooperation with the National Institute of Standards and Technology (NIST), which has helped 

benchmark and improve the quality of analytical data gathered on the marine environment by 

administering intercomparison exercises, GoMRI then launched the hydrocarbon intercalibration1 

experiment (HIE) to address the need for advancing the importance of laboratory quality 

assurance/quality control (QA/QC) practices and for interlaboratory comparison for hydrocarbon 

compounds. 

The GoMRI Research Board strongly encouraged all GoMRI-funded Principal Investigators, CoPrincipal Investigators, and other GoMRI collaborating laboratories to participate. Other members of the 

scientific community were invited and two commercial analytical laboratories (Alpha Analytical; 

Mansfield, MA and Battelle Memorial Institute; Duxbury, MA) who have analyzed 1,000s of samples 

following the Deepwater Horizon disaster were contracted to be involved in this effort. Researchers who 

studied other physical, chemical, and biological properties beyond hydrocarbons were invited to 

participate. 

It is important to note that the HIE was not intended to be a proficiency test, and that laboratory-specific 

results would be anonymous to all, including the GoMRI Research Board members, except for the HIE 

coordinators and their teams. 

Participants were requested to: 

 Report their results by December 1, 2014; 

 Share information on analytical methods used; 

 Allow NIST and GoMRI to use their results; 

 Be open to co-author a peer-reviewed manuscript; 

 Make a significant effort to attend a workshop to discuss the results of this study at the 2015 

GoMRI meeting in Houston, TX (February 16, 2015) 

Over thirty laboratories expressed interest and were supplied with two different reference samples for 

analysis as described in the next section. Due to delays and requests from many participants for additional 

time, the deadline was extended until noon February 16, 2015. Ultimately, 20 laboratories submitted 

results on traditional analytes, including saturated hydrocarbons, aromatic hydrocarbons, and biomarkers, 

measured by gas chromatography (GC). In addition to these traditional analytes, three laboratories 

reported results for an expanded range of analytes detected by Fourier Transform ion cyclotron resonance 

mass spectrometry (FT-ICR-MS). Toxicity, shear viscosity, and interfacial tension were also reported by 

additional laboratories. The results of the interlaboratory study were discussed at a workshop during the 

2015 GoMRI meeting in Houston, TX (February 16, 2015). 

This report provides a summary and discussion of the HIE results from participants who reported for 

three classifications of organic constituents: saturated hydrocarbons, aromatic hydrocarbons, and 

biomarkers. Results for the FT-ICR-MS, toxicity, shear viscosity, and interfacial tension are not reported 

here. These results will be a topic in an upcoming publication. 

1 While originally termed an "intercalibration", the spirit and goals of this effort are more accurately described as 

"intercomparison". Hence, the latter term will be used in this report.

SOURCE OF MATERIALS 

Participation by the laboratories was voluntary, and study samples were provided free of charge. 

Participants received two ampoules each of SRM 2779 Gulf of Mexico Crude Oil and the candidate SRM 

2777 Weathered Gulf of Mexico Oil. Each ampoule contained 1.3 mL of material. 

I.	 SRM 2779. The petroleum crude oil for SRM 2779 was collected on May 21, 2010, on the 

drillship Discoverer Enterprise from the insertion tube that was receiving oil directly from the 

Macondo well (MW) during response operations (Figure 1). Using the data from three 

independent methods of analysis performed at NIST as well as one set of data from an 

interlaboratory study of 36 participating laboratories coordinated by NIST and the National 

Oceanic and Atmospheric Administration (NOAA) [3], certified and reference values (as mass 

fractions) are provided for a number of polycyclic aromatic hydrocarbons (PAHs) along with 

reference values (as mass fractions) for a number of alkylated PAH groups, hopanes, and 

steranes, but not n-alkanes [2]. 

II.	 Candidate SRM 2777. This material was prepared from the Soxhlet extraction (90/10 

dichloromethane/methanol) of oiled sand-patties collected on August 31, 2012 at Gulf Shores 

Beach, Alabama (Figure 2). Geochemical analysis by Aeppli et al., revealed that the residue is 

weathered MW oil (sample B105 in reference [4]). Solvent was removed to yield a dark, syrupy 

liquid (Figure 3) that was diluted in toluene at approximately 71 mg/g. 

This material was chosen as a true “field” weathered sample and not a laboratory-weathered 

sample in light of recent studies showing that field weathering via biodegradation had removed 

some normal alkanes, branched alkanes, and other saturates [5-7]. In addition, the field-based 

studies have shown a formation of residues non-amenable to GC during "real world" conditions 

following the release, as revealed by mass balance tracked by elemental analysis, thin-layer 

chromatography, GC, and FT-ICR-MS [5,6]. It was considered important to include a fieldweathered sample with an increased amount of non-GC amenable materials relative to the 

majority of the traditionally measured analytes to provide analytical challenges representative of 

field samples. 

INSTRUCTIONS TO PARTICIPANTS 

Each participant was informed that the candidate SRM 2777 should be treated as an unknown sample and 

SRM 2779 as a control material with assigned values for many analytes. They were asked to remove 

three subsamples from one ampoule of SRM 2779 and three subsamples from one ampoule of candidate 

SRM 2777 and treat each subsample with their laboratory’s and/or program’s analytical protocols. An 

Excel spreadsheet (see Appendix A for an example spreadsheet) was sent to each participant with specific 

instructions on how to report values for only the analytes they typically measure and other details. Select 

3
 
 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

alkanes, aromatics, and biomarkers were listed on the spreadsheet, however, if the spreadsheet did not fit 

within the analytes or properties studied, reports or memos were accepted. The remaining ampoule of 

each material would be available to the participants for their own use. The instruction letter that was sent 

to the participants is provided in Appendix A. 

METHODS 

Participants were asked to use analytical protocols currently used within their laboratory for the analytes 

to be determined. A wide range of approaches were used; one laboratory reported results by two 

independent protocols and one laboratory reported results by three independent protocols. Each data set 

was independently evaluated as indicated by a unique laboratory code. All analytical protocols utilized 

GC for separation; two laboratories used two-dimensional GC (GCxGC). Flame ionization detection 

(FID) and various forms of mass spectrometry (MS) and tandem mass spectrometry (MS-MS) were used 

for detection. Some laboratories included sample processing steps to remove matrix interferences, while 

other laboratories analyzed the samples without cleanup. Both internal and external approaches to 

calibration were employed. In some instances, reference compounds were not readily available for 

quantification of individual components. In such cases, some laboratories used a “representative 

compound” for quantification, with the assumption that the response factor for the representative 

compound would provide a valid estimate of the compound(s) under study. For example, a response 

factor of a parent PAH was sometimes used to quantify an alkyl PAH group. A summary of method 

information provided by each laboratory is provided in Appendix B. 

EVALUATION OF EXERCISE RESULTS 

Laboratory data submission: Each participating laboratory was asked to submit data from three replicate 

determinations of the “unknown” candidate SRM 2777 material and the control material SRM 2779. 

Laboratories were requested to report these results to three significant figures. 

Treatment of Data: The laboratories reporting values for alkane, aromatic, and biomarkers were assigned 

numerical identification codes. Twenty laboratories reported results for one or more of these analyte 

groups (Tables 1- 12). (Please note that some research groups used more than one analytical method, 

such as using two different types of GCs). For ease, we treated each analytical method as a “laboratory”. 

The data were collected and input into ProLab Plus (quo data GmbH, Dresden Germany, version 

2016.1.15.0) for data analysis using ISO 5725-2 standard (ISO 1994) [8]. For each analyte reported, a 

summary page was generated (Appendix C). Each summary page includes a graphical presentation of the 

individual measurements reported by participating laboratories, and a tabular summary of this data. 

Summary statistics are provided for each analyte that show the results obtained from each participating 

laboratory, the mean and the median of all reported values, the certified or reference value for SRM 2779 

when available, the uncertainty representing the 95 % confidence level (indicated as green shaded bands), 

and the range of z-scores from -3 to 3 (indicated as red lines labeled “limit of tolerance”). The 

reproducibility standard deviation and repeatability standard deviation were calculated for each analyte 

using ISO 5725-2. The reproducibility standard deviation characterizes the variability between 

laboratories and the repeatability standard deviation characterizes the variability within the laboratories. 

To assess the accuracy of each laboratory, z-scores were calculated for each laboratory for each analyte.

Generally, the z-score is calculated using the following equation: 

z = (x-xa)/σ ; 

where x is the result from an individual laboratory, xa is the assigned value and σ is the standard deviation 

of the test results [9]. In this study, z-scores were calculated using an assigned value xa calculated from 

the mean of all reported values, and the reproducibility standard deviation for σ. Outlier detection was 

limited to removal of data only if the laboratory exceeded an absolute z-score value greater than 3 (the 

Grubbs and Cochran tests indicated in ISO 5725-2 were not applied). Consequently, almost all of the data 

were used in calculation of the means. Outliers are indicated in the summary charts in red. Appendix C is 

organized with data presented alphabetically by analytes for the three analyte categories, with 

subcategorization for SRM 2777 and SRM 2779. 

A few laboratories reported results that did not conform to the instructions, and modifications to the data 

were required after submission. Laboratories were asked to report mass fraction values of analytes in 

microgram per gram of SRM material. For candidate SRM 2777, laboratories 6, 8, and 9 originally 

reported values as microgram per gram of source weathered oil instead of the ampouled solution by using 

the concentration of weathered oil in toluene in candidate SRM 2777 that was provided in the instruction 

letter. As a result, these results were uniformly biased by this common factor. After confirming with the 

individual laboratories, an adjustment was made to convert their reported mass fractions from microgram 

per gram of weathered oil to microgram per gram of candidate SRM material. The results in this report 

for laboratories 6, 8, and 9 for candidate SRM 2777 are the adjusted values. It should be noted that the 

values these laboratories reported for SRM 2779 were not affected and values listed in this report are 

unchanged. Results for Laboratory 10 were also reported as mass fraction of weathered oil instead of the 

diluted ampouled solution; however, this laboratory physically removed the solvent before performing 

analysis on the material. In this case, we assumed that analytes were unaffected by solvent evaporation 

since most volatile components were eliminated by the weathering process. Corrections were applied to 

these data by using the mass fraction of weathered oil in solution to adjust levels to be consistent with the 

instructions. 

Laboratory 18 provided data for two analytes. Levels were reported as an average with an associated 

standard deviation; individual levels for the replicates were not provided. Only the averages were utilized 

in the statistical analyses for this intercomparison exercise. 

Several laboratories reported results for additional analytes not listed on the Data Submission Form. 

Most of these analytes were alkylated PAHs, although laboratory 2 reported extensive information for 

additional biomarkers. A summary of the additional data is provided in Appendix D. 

Data were submitted by one additional laboratory, designated Lab 21, significantly after the closing date 

for the intercomparison exercise. This data set was not included in the statistical analysis and does not 

appear on the summary pages in Appendix C. The data are reported as received is located in Appendix E 

along with the average and standard deviation of the replicates. The methods used by laboratory 21 are 

reported along the rest of the laboratories in Appendix B.

DISCUSSION 

Results for SRM 2779 

a. Normal alkanes. Five to twelve labs reported some data for n-alkanes and the branched hydrocarbons, 

pristane and phytane (Table 1). The mean mass fractions for each laboratory for n-alkanes in SRM 2779 

are listed in Table 5 and the summary pages for these analytes are located in Appendix C pages C31-C61. 

It was unexpected that only a few laboratories would submit results for n-alkanes since these compounds 

constitute the most abundant class of compounds in oil, and analytical standards are readily available. 

Alkanes are also often well resolved by gas chromatographic columns, as is the case for the Macondo 

well oil. In addition, saturated hydrocarbons are frequently used for gauging the extent of weathering, 

especially evaporation and biodegradation. 

The results varied among laboratories that submitted data. For example, n-pentadecane ranged from 2890 

mg/kg to 6020 mg/kg with an HIE mean and uncertainty of 4650 mg/kg ± 654 mg/kg (Table 5). The 

mean mass fraction and standard deviation for n-alkanes ranging from C10-C25 exhibit greater variability 

in the smaller and more volatile alkanes. This could be a result of sample handling, calibration 

differences among laboratories, or sample contamination. Three laboratories (9, 10, and 14) that reported 

values for normal alkanes with some sample preparation or clean-up beyond dilution did not have any 

apparent patterns due to this additional handling. 

b. Polycyclic aromatic hydrocarbons. Parent and alkylated PAHs were determined by more participants 

than the other compound classes (2 to 16 laboratories; Tables 2 and 3) despite the relatively low levels of 

PAHs compared with the n-alkanes. Interest in these compounds may be attributed to the known 

bioactivity of PAHs. PAHs are frequently used to identify sources (petrogenic vs. pyrogenic) [10], to 

characterize the degree of abiotic and biotic weathering [11], and to fingerprint oils (e.g., alkylated 

phenanthrenes/anthracenes vs. alkylated dibenzothiophenes [12]). The Certificate of Analysis for SRM 

2779 has both certified and reference values available for many of the PAHs determined in this study to 

which the participants could refer to before submitting results. 

The mean values of each laboratory for PAHs and alkylated PAHs are listed in Tables 6 and 7, 

respectively, and the summary pages for these analytes are located in Appendix C, pages C124-C195. 

Overall, the ranges in participant-reported values for parent PAHs and alkylated PAHs were similar, and 

levels reported were comparable to the values listed in the Certificate of Analysis [2]. For example, the 

HIE mean for phenanthrene (287 mg/kg ± 31.9 mg/kg) were within the expanded uncertainty of the 

certified value for phenanthrene (258 mg/kg ± 27 mg/kg). For PAHs at lower concentrations, the HIE 

mean values were also similar to those in the Certificate of Analysis, but with a greater uncertainty (e.g., 

benzo[e]pyrene (12.7 mg/kg ± 3.01 mg/kg vs. certified value 10.8 mg/kg ± 0.6 mg/kg) and fluoranthene 

(5.01 mg/kg ± 1.42 mg/kg vs. certified value 4.4 mg/kg ± 0.4 mg/kg)). 

The results for alkylated PAHs, e.g., C1-phenanthrenes/anthracenes (724 mg/kg ± 90.1 mg/kg vs. the 

reference value 670 mg/kg ± 90 mg/kg) were not as tightly grouped as for phenanthrene even though they 

occurred at much higher concentrations. This may be attributable to subjective bias introduced as a 

consequence of integration of numerous peaks (that are assumed to constitute the C1­

phenanthrene/anthracene compounds, unresolved by GC-MS). With this approach, each laboratory used 

a response factor based on the parent compound (or similar) to quantify the parent and alkylated PAHs, 

which may also have also introduced variability. It should be noted that many of the reference values for 

6
 
 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

alkylated PAHs in SRM 2779 were derived from the 2010 intercomparison, with a majority of the labs 

using the response factors of the parent PAHs [3]. 

One participating laboratory based their quantitation on the response of other reference standards they 

considered to be more representative of alkylated PAHs. For example, this laboratory used the response 

factor of 1-methylphenanthrene to quantify the C1-phenanthrenes/anthracenes. The use of alkylated 

reference standards for quantitation of alkyl-substituted PAH isomers may be more defensible than the 

more common use of the parent PAH; however, this approach often resulted in values somewhat different 

than those reported by the HIE participants and listed in the Certificate of Analysis for SRM 2779 (see 

Figure 4) [2]. Thus, it is important that labs describe how they determine alkylated PAHs to ensure 

values from different laboratories can be compared. 

c. Biomarkers. Only eight out of twenty laboratories provided results for biomarkers in SRM 2779 

(Table 4), despite the fact that biomarkers are a key factor for oil spill forensics, and that reference values 

were available in the Certificate of Analysis. For each biomarker, between two to eight laboratories 

(Table 4) provided results. The use of petroleum biomarkers in fingerprinting oil spills and in assigning 

source specificity relies on the relative stability of these compounds towards abiotic and biotic 

degradation processes. Thus, biomarkers are often used as reference compounds to which the weathering 

of relatively less stable compounds or the formation of new compounds can be compared and/or 

normalized. 

The mean values reported for biomarkers for SRM 2779 are listed in Table 8 and the summary pages for 

these analytes are located in Appendix C, pages C224-C250. For 17α(H),21β(H)-hopane, the biomarker 

most often used as an “internal” standard for weathering and fingerprinting, intercomparison results were 

consistent with SRM 2779. Seven of the eight laboratories were within the mean uncertainty range (51.4 

mg/kg ± 6.2 mg/kg vs. reference value 42 mg/kg ± 10 mg/kg) and five were within the uncertainty range 

of the reference value in the Certificate of Analysis. Alternatively, the results for 17α(H),22,29,30­

trisnorhopane (9.19 mg/kg ± 2.02 mg/kg vs. reference value 7.29 mg/kg ± 0.79 mg/kg) and 

5α(H),14β(H),17β(H)-cholestane-20R (29.3 mg/kg ± 6.04 mg/kg vs. reference value 23.7 mg/kg ± 2.7 

mg/kg) were within the uncertainties of the reference, but there was greater scatter among the data 

reported by the laboratories. Unlike the n-alkanes and PAHs, pure standards and isotope-labeled 

biomarker internal standards are costly and often not commercially available, which may explain the 

variability among the data for the biomarkers. In fairness, it is well recognized that biomarker analysis 

need only be internally consistent within each laboratory [13], although laboratories should strive for 

more external consistency. 

Results for Candidate SRM 2777 

The mean values reported for alkanes, PAHs, alkylated PAHs, and biomarkers for candidate SRM 2777 

are listed in Tables 9-12, respectively, and individual laboratory results are reported in Appendix C. This 

sample presented significant challenges to most of the laboratories due to extreme weathering, and 

subsequent lower analyte levels. For example, the reported value from the HIE, for phenanthrene was 

287 mg/kg ± 31.9 mg/kg in SRM 2779 vs. 0.607 mg/kg ± 0.244 mg/kg in candidate SRM 2777 (Tables 6 

and 10 and appendix C, page C120). In general, candidate SRM 2777 presented significant analytical 

challenges that limited the number of analytes that could be characterized.

DIRECTIONS FOR 2014 HYDROCARBON INTERCALIBRATION EXPERIMENT (HIE)
 

1.	 SAMPLES FOR ANALYSIS: The study consists of the analysis of two samples: a neat oil 

sample (SRM 2779) and a toluene solution of a weathered oil sample (Candidate SRM 2777) 

- SRM 2779 Gulf of Mexico Crude Oil 

This material was prepared with crude oil that was collected on May 21, 2010 from the Discoverer 

Enterprise from the insertion tube that was receiving oil directly from the Macondo well during response 

operations. Technical details are available at https://wwws.nist.gov/srmors/view_detail.cfm?srm=2779. 

-Candidate SRM 2777 Weathered Gulf of Mexico Oil 

This material was prepared from the Soxhlet extraction (90/10 dichloromethane/methanol) of oiled sand 

patties collected on August 31, 2012 at Gulf Shores Beach, Alabama. Geochemical analysis revealed that 

the residue is weathered Macondo well oil (Aeppli et al., 2014; sample B105; Table S2). Solvent was 

removed to yield a dark, syrupy liquid that was diluted in toluene at approximately 71 mg/g. 

For this study the weathered oil sample is an unknown sample and SRM 2779 is a control material with 

assigned values for many (not all) of the target analytes. However, results for SRM 2779 for analytes that 

do not currently have values assigned may be used to assign additional values to the SRM. 

You will receive two ampoules of SRM 2779 and two ampoules of Candidate SRM 2777. Each ampoule 

contains approximately 1.3 mL. You are only required to report triplicate analyses from one of the two 

ampoules for each sample. 

2.	 STORAGE OF SAMPLES: Sealed ampoules, as received, should be stored in the dark at 

temperatures between 10 °C and 30 °C. 

3.	 INSTRUCTIONS FOR USE: You are requested to analyze SRM 2779 and Candidate SRM 

2777 using your laboratory’s and/or program’s analytical protocols. 

Prior to opening the ampoules, you should sonicate the sample in the ampoule. Samples for 

analysis should be withdrawn immediately after opening the ampoule and should be processed 

without delay. Material should not be stored in ampoules that have been opened, even if they are 

resealed. 

4.	 ANALYZE IN TRIPLICATE THROUGHOUT ENTIRE METHOD: For best success of this 

experiment, we ask that you analyze three subsamples from one ampoule of each sample using 

your entire analytical method. That is, do not just inject the same prepared material for analysis 

three times in your instrument. Rather draw three subsamples from each ampoule and treat each 

subsample separately by carrying it throughout your analytical methods for measuring your target 

analytes. Ideally, analyze the three subsamples at the same time to limit variability. For Candidate 

SRM 2777, report the ampoule identification number for the ampoule you used in the spreadsheet 

(both box number and ampoule number). Only report the results of the triplicate analysis. 

5.	 REPORT ONLY WHAT YOU ROUTINELY MEASURE. In the spreadsheet, we have listed 

the target analytes for this experiment. You are not required to measure each analyte listed. For 

example, if you do not routinely measure a specific compound, do not start with this experiment. 

We have prepared the spreadsheet to reflect differences in how you report certain compounds. 

For example, some labs separate triphenylene and chrysene and report values for each. Other labs 

report the sum of both compounds. In the spreadsheet, you have the opportunity to report the 

A2
 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

results either way but do not report both ways. 

Report results in μg/g. Report the date of analysis of each sample in the requested m/d/y format. 

We prefer that concentration values be reported for each analyte determined. However, if you 

need to report non-numerical data please use the following conventions: 

NA “Not analyzed”, “not determined” 

<”value” “Less than specified concentration”, e.g., <8 μg/g 

Other “Other”; add note of explanation at end of data table, e.g., interference 

DL “Below detection limit” may be used however <”value” is preferable 

Do not use negative numbers or parentheses to indicate “less than detection limits”. The 

spreadsheet also includes places for you to list the surrogate/internal standards and type of 

calibration curve used and provide a brief description of the analyses. Please do not add spaces 

before entering numbers in the table cells and enter them as "numbers" not as "labels". Please do 

not insert any columns or rows within the table in the data file. 

You may list results from non-routine analysis or non-targeted compounds in the spreadsheet in 

the ”Additional Compounds and Information” section. 

6.	 SEND RESULTS BY DECEMBER 1, 2014. The results are due by December 1, 2014, but can
