7 Introduction
Results are reported for the analysis of a series of sediment, leachate, and sludge samples received by Centre Analytical Laboratories, Inc. (Centre) from the 3M Environmental Laboratory. The samples were collected from Columbus, Georgia and are part of 3M Project W2336. The Centre study number assigned to the project is 023-014.
Specific fluorochemicalcharacterization by liquid chromatography/ tandem mass spectrometry (LC/MS/MS) was requestedfor all samples. A total of 9 samples were received for analysis.
The samples were prepared and analyzed by LC/MS/MS for the following list of fluorochemicals:

The analytical methods used for originally developed for water samples and were validated by Centre. The water sample validation protocol and results are on file with Centre. The methods were modifiedfor the sediment and sludge samples. The procedures have not been fully validated for these matrices. Data presentedhere is the highest quality data available at this time.
2 Sample Receipt
The samples were submitted in individual plastic containers and were not preserved. Seven individual sample containers were received. Samples were received on 7/28/00. Sample
collection dates were not supplied. Chain-of-custody information is presented in Attachment C.
3 Holding Times
The analytical method used was validated against a maximum holding time of 14 days in water samples. Stability after this time period has not been validated. However, it should be noted that field fortifications in water and other matrices have shown acceptable recoveries at 100 and 1000 ngR for periods longer than 14 days.

4 Methods - Analytical and Preparatory
4.1 LC/MS/MS
4.1.1 Sample Preparation for LC/MS/MS Analysis
Water samples (leachate and field blanks) were initially treated with 200 UL of 250 mg/L sodium thiosulfate solution to remove residual chlorine. Solid phase extraction (SPE) was used to prepare the samples for LC/MS/MS analysis. A forty-milliliter portion of sample was transferred to a CIS SPE cartridge. The cartridge was first eluted with 5 mL of 40% methanol in water solution. The eluate was discarded and the SPE column was then eluted with 100% methanol. A 5 mL portion of methanol was collected for analysis by LC/MS/MS. This treatment resultedin an eight-foldconcentration of the samples prior to analysis.
For the sediment and sludge samples, a representative portion of sample (5 grams) was first extracted into 5 ml of methanol. The extracts were filtered and diluted to a final volume of 40 mL with Type I water. The diluted extracts were then treated in the same manner as the water samples, beginningwith the solid phase extraction.
4.1.2 Sample Analysis by LCIMSIRIIS
In HPLC, an aliquot of extract is injected and passed through a liquid-phase chromatographic column. Based on the affinity of the analyte for the stationary phase in the column relative to the liquid mobile phase, the analyte is retained for a characteristic amount of time. Following HPLC separation, ES/MS provides a rapid and accurate means for analyzing a wide range of organic compounds, including fluorochemicals. Electrospray is generally operated at relatively mild temperatures; molecules are ionized, fragmented, and detected. Ions characteristic of known fluorochemicals are observed and quantitatedagainst standards.
A Hewlett-PackardHP1100 HPLC system coupledto a Micromass Ultima MS/MS was usedto analyze the sample extracts. Analysis was performed using selected reaction monitoring (SRM). Samples were extracted between 8/25/00 and 8/28/00 and analyzed by MS/MS between 8/28/00 and 8/29/00. The HPLC and MS/MS methods used for analysis and
instrument parameters can be found in Attachments D.
5 Analysis
5.1 Calibration
A 7-point calibration curve was analyzed at the beginning and end of the analytical sequence for the compounds of interest. The calibration points were prepared at 0, 25, 50, 100, 250, 500, and 1000 ng/L (ppt) for LC/MS/MS analysis. The instrument response versus the concentration was plottedfor each point. Using linear regressionwith l/x weighting, the slope,
y-intercept and correlation coefficient (r) and coefficient of determination (P) were determined. A calibrationcurve is acceptable if r 20.985 (12 2 0.970).
Calibrationstandards are preparedusing the same SPE procedure usedfor samples.
Calibration check standards were analyzed periodically (every three to five sample injections) throughout the analysis sequence. Compliance is obtained if the standard analyte concentrations are within +/-20% of the actual value.
BACK TO MAIN
For the results reported here, calibration criteria were met.
5.2 Blanks
Extraction blanks were prepared and analyzed with every extraction batch of samples. The extraction blanks should not have any target analytes present at or above the concentration of the low-levelcalibrationstandard. For these samples, the extraction blanks were compliant.
Instrument blanks in the form of clean methanol solvent were also analyzed after every highlevel calibration standard, and after known high-level samples. Again, the blanks should not have any target analytes present at or above the low-level calibration standard. For the samples presentedhere the instrument blanks are compliant.
5.3 Surrogates
Surrogate spikes are not a component of the LC/MS/MS analytical methods.
5.4 Matrix Spikes
Matrix spikes were prepared for every field sample using all compounds of interest. Matrix spike recoveries are given in Attachment B. No field spikes were collectedfrom this site.
5.5 Duplicates
All field samples were analyzed in duplicate. Results are given along with the sample results in Attachment A.
5.6 Laboratory Control Samples
For LC/MS/MS analyses, Milliq water was spiked with all compounds of interest at 25 and 250 ng/L during each extraction set. All recoveries for all compounds were between 70-130% in each LCS. Results are given along with the raw data in Attachments D.
5.7 Sample Related Comments
Empty containers were submitted as filed blanks. The containers were treated with 40 mL of Milliq water and analyzed as per the method. There are no other sample related comments for this data set.
6 Data Summary
Please see Attachment A for a detailed listing of the analytical results. Field blank water and leachate results are reported in parts per trillion (ppt) (ngR). Sediment and sludge sample results are reported in parts per billion (ppb) (ug/Kg) on both an as-received and dry-weight basis.
7 DatdSample Retention
Samples are disposed of one month after the report is issued unless otherwise specified. All electronic data is archived on retrievable media and hard copy reports are stored in data folders maintained by Centre.
