LABORATORY NARRATIVEModified TO-15 SIM

ERM-WestWorkorder# 0509028

Two 6 Liter Summa Canister (SIM Certified) samples were received on September 01, 2005. The laboratory performed analysis via modified EPA Method TO-15 using GC/MS in the SIM acquisition mode. The method involves concentrating up to 0.5 liters of air. The concentrated aliquot is then flash vaporized and swept through a water management system to remove water vapor. Following dehumidification, the sample passes directly into the GC/MS for analysis.

Method modifications taken to run these samples include:Requirement ATL ModificationsTO-15Blank and standards Zero air Nitrogen

Dilutions for initial calibration Dynamic dilutions or static using canisters.

Syringe dilutions may also be utilized.

Date: 26 September 2005

Subject: Data Review of 1000 Hampton Drive (UPRR Hookston Station) Samples Collected 29 August 2005

Project Number: 0020557.10

Data Package: Air Toxics Data Package 0509028

The quality of the data was assessed and any necessary qualifiers were applied following the USEPA Contract Laboratory Program National Functional Guidelines for Organic Data Review, October 1999.

HOLDING TIME AND PRESERVATION EVALUATION

The samples were prepared and analyzed within the method prescribed time period from the date of collection. None of the data were qualified based on holding time exceedances.

BLANK EVALUATION

The method blank sample results were nondetected for each of the target analytes. No data required qualification based on blank results.

BLANK SPIKE EVALUATION

The laboratory control sample (LCS) percent recoveries (%R) were within the laboratory’s limits of acceptance, indicating acceptable accuracy. No data required qualification based on LCS results.

SURROGATE SPIKE EVALUATION

The surrogate recoveries were within acceptable limits. No qualifications to the data were made. The surrogate recoveries indicate minimal matrix interference in the samples.

P A G E 2

CANISTER VACUUM EVALUATION

One sample was received in the laboratory with zero vacuum. All compounds in that sample are qualified as estimated (J/UJ) as shown in Table 1.

OVERALL ASSESSMENT

No data required rejection. All of the data, including qualified data, can be used for decision-making purposes; however, the limitations indicated by the applied qualifiers should be considered when using the data. The quality of the data generated during this investigation is acceptable for the preparation of technically defensible documents.

ANALYTICAL DUPLICATE EVALUATION

One analytical duplicate sample was prepared in the laboratory and analyzed. ERM calculated the RPDs between detected results. The USEPA has not established control criteria for duplicate samples; therefore, sample data are not qualified on the basis of duplicate imprecision. The RPDs are presented in Table 1.

CALIBRATION EVALUATION

The continuing calibration verification sample was slightly below control limits for methyl tert-butyl ether. All associated sample results were qualified as estimated (UJ) for methyl tert-butyl ether. These qualifications can be found in Table 1.

FIELD DUPLICATE EVALUATION

One sample was collected, prepared, and analyzed in duplicate. ERM calculated the RPDs between detected results. The USEPA has not established control criteria for duplicate samples; therefore, sample data are not qualified on the basis of duplicate imprecision. All RPDs were less than 10 percent, indicating acceptable precision. The RPDs are presented in Table 1.

OVERALL ASSESSMENT

No data required qualification or rejection. All of the data can be used for decision-making purposes. The quality of the data generated during this investigation is acceptable for the preparation of technically defensible documents.

Three 6 Liter Summa Canister (SIM Certified) samples were received on August 26, 2005. The laboratory performed analysis via modified EPA Method TO-15 using GC/MS in the SIM acquisition mode. The method involves concentrating up to 0.5 liters of air. The concentrated aliquot is then flash vaporized and swept through a water management system to remove water vapor. Following dehumidification, the sample passes directly into the GC/MS for analysis.

BLANK EVALUATION




P A G E 2



ANALYTICAL DUPLICATE EVALUATION

One sample was prepared and analyzed as a duplicate in the laboratory. ERM calculated the RPDs between detected results. The USEPA has not established control criteria for duplicate samples; therefore, sample data are not qualified on the basis of duplicate imprecision. All RPDs were less than 10 percent, indicating acceptable precision. The RPDs are presented in Table 2.
