Dear Mrs. Niedermayer:

EB Solutions, Inc., on the behalf of VA Central Iowa Health Care System and the Department of Veterans

Affairs, appreciates the opportunity to submit this closure report at the above referenced Site.

Soil analytical results for benzene, toluene, ethylbenzene, and xylenes are below Iowa Department of Natural

Resources Tier 1 target levels. The soil concentrations for TEH diesel at P1 is above the Iowa Department of

Natural Resources target level of 3,800 mg/kg with a concentration of 4,600 mg/kg. The remaining concentrations of TEH diesel at S1, S2, and S3 are below Iowa Department of Natural Resources Tier 1 target levels. Groundwater analytical results for toluene, ethylbenzene, xylenes, and TEH are below Iowa

Department of Natural Resources Tier 1 target levels. The benzene concentrations at TMW1 was above the

Tier 1 target level of 5 µg/L with a concentration of 48.2 µg/L. TEH waste oil in groundwater laboratory detection limit at TWM1 and TMW2 was at <525 µg/L.

EB Solutions, Inc. recommends that the Site have an Iowa Department of Natural Resources Tier 1 Assessment completed for the pump island and tank basin with tank 1 and tank 2.

If there are any questions, please contact us at 319-531-8487.

Was there an odor or visible staining noticed from any of the soil samples? If so which samples?

The above soil analytical results are reported in mg/kg. Tanks 1 and tank 2 were in one tank pit with a pump island adjacent to the west of the tanks. Tank 3 was located in a separate tank pit located adjacent to a generator building. The soil beneath the pump island (P1) adjacent west of tank 1 and on the west side of the diesel tank 1 had visual signs of impact. Also, the soil beneath the pump island had a diesel odor. The soil beeath tank 1, tank 2, and tank 3 did not show signs of impact. The remaining soil in the tank pit and beneath the piping did not show signs of staining or odor.

Was bedrock present?

No

Was the backfill returned to the tank pit?

Yes, the backfill was returned to the tank excavation.

Was there a petroleum sheen or odor noticed from any of the groundwater samples? If so, which samples?

The above groundwater analytical results are reported in ug/L. TMW1 was located to the north side of the tank pit with tank 1 and tank 2. TMW2 was located to the north of the tank pit with tank 3. During the groundwater, a sheen or visual signs of impacted of groundwater was not observed.

Discussion/Recommendations (based on lab results and visual observations):

Soil analytical results for benzene, toluene, ethylbenzene, and xylenes are below Iowa Department of Natural Resources Tier 1 target levels. The soil concentrations for TEH diesel at P1 is above the Iowa Department of Natural Resources target level of 3,800 mg/kg with a concentration of 4,600 mg/kg. The remaining concentrations of TEH diesel at S1, S2, and S3 are below Iowa Department of Natural Resources Tier 1 target levels. Groundwater analytical results for toluene, ethylbenzene, xylenes, and TEH are below Iowa Department of Natural Resources Tier 1 target levels. The benzene concentrations at TMW1 was above the Tier 1 target level of 5 ug/L with a concentration of 48.2 ug/L. TEH waste oil in groundwater laboratory detection limit at TWM1 and TMW2 was at <525 ug/L. EB Solutions, Inc. recommends that the Site have an Iowa Department of Natural Resources Tier 1 Assessment completed for the pump island and tank basin with tank 1 and tank 2.

ONE LAB. NATIONWIDE.CASE NARRATIVE

All sample aliquots were received at the correct temperature, in the proper containers, with the appropriate preservatives, and within method specified holding times. All MDL (LOD) and RDL (LOQ) values reported for environmental samples have been corrected for the dilution factor used in the analysis. All radiochemical sample results for solids are reported on a dry weight basis with the exception of tritium, carbon-14 and radon, unless wet weight was requested by the client. All Method and Batch Quality Control are within established criteria except where addressed in this case narrative, a non-conformance form or properly qualified within the sample results. By my digital signature below, I affirm to the best of my knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the quality of the data have been identified by the laboratory, and no information or data have been knowingly withheld that would affect the quality of the data.

ONE LAB. NATIONWIDE.GLOSSARY OF TERMS

Guide to Reading and Understanding Your Laboratory Report

The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative.

Abbreviations and Definitions

(dry) Results are reported based on the dry weight of the sample. [this will only be present on a dry report basis for soils].

MDL Method Detection Limit.

ND Not detected at the Reporting Limit (or MDL where applicable).

RDL Reported Detection Limit.

Rec. Recovery.

RPD Relative Percent Difference.

SDG Sample Delivery Group.

(S) Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media.

U Not detected at the Reporting Limit (or MDL where applicable).

Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported.

Dilution If the sample matrix contains an interfering material, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor.

Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges.

Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG.

Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.

Result

The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte.

Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.

Quality Control Summary (Qc)

This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material.

Sample Chain of Custody (Sc)

This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis.

Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported.

Sample Summary (Ss) This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis.

Qualifier Description

B The same analyte is found in the associated blank.

J The identification of the analyte is acceptable; the reported value is an estimate.

ONE LAB. NATIONWIDE.CASE NARRATIVE

All sample aliquots were received at the correct temperature, in the proper containers, with the appropriate preservatives, and within method specified holding times. All MDL (LOD) and RDL (LOQ) values reported for environmental samples have been corrected for the dilution factor used in the analysis. All radiochemical sample results for solids are reported on a dry weight basis with the exception of tritium, carbon-14 and radon, unless wet weight was requested by the client. All Method and Batch Quality Control are within established criteria except where addressed in this case narrative, a non-conformance form or properly qualified within the sample results. By my digital signature below, I affirm to the best of my knowledge, all problems/anomalies observed by the laboratory as having the potential to affect the quality of the data have been identified by the laboratory, and no information or data have been knowingly withheld that would affect the quality of the data.

ONE LAB. NATIONWIDE.GLOSSARY OF TERMS

Guide to Reading and Understanding Your Laboratory Report

The information below is designed to better explain the various terms used in your report of analytical results from the Laboratory. This is not intended as a comprehensive explanation, and if you have additional questions please contact your project representative.

Abbreviations and Definitions

MDL Method Detection Limit.

ND Not detected at the Reporting Limit (or MDL where applicable).

RDL Reported Detection Limit.

Rec. Recovery.

RPD Relative Percent Difference.

SDG Sample Delivery Group.

(S) Surrogate (Surrogate Standard) - Analytes added to every blank, sample, Laboratory Control Sample/Duplicate and Matrix Spike/Duplicate; used to evaluate analytical efficiency by measuring recovery. Surrogates are not expected to be detected in all environmental media.

U Not detected at the Reporting Limit (or MDL where applicable).

Analyte The name of the particular compound or analysis performed. Some Analyses and Methods will have multiple analytes reported.

Dilution If the sample matrix contains an interfering material, or if concentrations of analytes in the sample are higher than the highest limit of concentration that the laboratory can accurately report, the sample may be diluted for analysis. If a value different than 1 is used in this field, the result reported has already been corrected for this factor.

Limits These are the target % recovery ranges or % difference value that the laboratory has historically determined as normal for the method and analyte being reported. Successful QC Sample analysis will target all analytes recovered or duplicated within these ranges.

Original Sample The non-spiked sample in the prep batch used to determine the Relative Percent Difference (RPD) from a quality control sample. The Original Sample may not be included within the reported SDG.

Qualifier This column provides a letter and/or number designation that corresponds to additional information concerning the result reported. If a Qualifier is present, a definition per Qualifier is provided within the Glossary and Definitions page and potentially a discussion of possible implications of the Qualifier in the Case Narrative if applicable.

Result

The actual analytical final result (corrected for any sample specific characteristics) reported for your sample. If there was no measurable result returned for a specific analyte, the result in this column may state “ND” (Not Detected) or “BDL” (Below Detectable Levels). The information in the results column should always be accompanied by either an MDL (Method Detection Limit) or RDL (Reporting Detection Limit) that defines the lowest value that the laboratory could detect or report for this analyte.

Case Narrative (Cn) A brief discussion about the included sample results, including a discussion of any non-conformances to protocol observed either at sample receipt by the laboratory from the field or during the analytical process. If present, there will be a section in the Case Narrative to discuss the meaning of any data qualifiers used in the report.

Quality Control Summary (Qc)

This section of the report includes the results of the laboratory quality control analyses required by procedure or analytical methods to assist in evaluating the validity of the results reported for your samples. These analyses are not being performed on your samples typically, but on laboratory generated material.

Sample Chain of Custody (Sc)

This is the document created in the field when your samples were initially collected. This is used to verify the time and date of collection, the person collecting the samples, and the analyses that the laboratory is requested to perform. This chain of custody also documents all persons (excluding commercial shippers) that have had control or possession of the samples from the time of collection until delivery to the laboratory for analysis.

Sample Results (Sr) This section of your report will provide the results of all testing performed on your samples. These results are provided by sample ID and are separated by the analyses performed on each sample. The header line of each analysis section for each sample will provide the name and method number for the analysis reported.

Sample Summary (Ss) This section of the Analytical Report defines the specific analyses performed for each sample ID, including the dates and times of preparation and/or analysis.

Qualifier Description

J3 The associated batch QC was outside the established quality control range for precision.
