RE: Des Moines South Area Source Control (SASC) RI/FS Progress Report for January, February and March 1990

Dear Mr. Curtis:

ECKENFELDER INC. initiated the SASC RI field tasks in October, 1989. Field operations were suspended in December due to severe cold weather and a force majeure was declared (December 22, 1989 letter from Charles F. Lettow to Glenn M. Curtis). No field operations were conducted in January or February, 1990. ECKENFELDER INC. and Layne-Western Company remobilized to the site on March 26, 1990 and drilling operations resumed on March 27, 1990. The following tasks were completed by ECKENFELDER INC. in the first quarter of 1990:

Geophysical Survey Technical Memorandum

The Geophysical Survey Technical Memorandum was completed and submitted to the USEPA.

Underground Utilities Survey Technical Memorandum

The Underground Utilities Survey was completed and submitted to the USEPA.

Performance and Systems Audit

Mr. Michael R. Brother, ECKENFELDER INC.'s QA/QC officer, has conducted a Performance and Systems Audit of available field-generated data acquired during field activities prior to the force majeure declaration. The results of Mr. Brother's audit are presented as a memorandum (Attachment I). Identified deviations from the Sampling and Analysis Plan (SAP) were addressed when field activities resumed.

Deep Soil Borings

Seven deep soil borings were completed the week ending March 31, 1990 and samples were submitted for laboratory analyses in accordance with the SAP. The completed deep borings are as follows:

DB-9 DB-11 DB-12 DB-13

DB-14 DB-37 DB-38

ANALYTICAL RESULTS

During the first quarter of 1990, ECKENFELDER INC. received analytical results from the University Hygienic Laboratory (UHL) for a portion of the samples submitted to date. The volatile organics, inorganics, and pesticide/PCB results have been summarized in Tables 1, 2, and 3, respectively, listing only those parameters that were detected in each sample.

Semi-volatile organics analytical results were received for two soil samples: DB-43 0'-2' (T) and DB-55 6'-8' (T). With respect to sample DB-43 0'-2' (T), no target semi-volatile organic compounds were detected. Several tentatively identified semi-volatile organic compounds (not on the Hazardous Substance List, HSL) were detected. For sample DB-55 6'-8' (T), three target semi -vo1 ati1e organic compounds were detected. The compound 2,4-dichlorophenol had a concentration of 4,000 ppb and the compounds naphthalene and 2,4,6-trichlorophenol had estimated concentrations of 140 ppb and 290 ppb, respectively, both below the practical quantitation limit. This sample also revealed a number of tentatively identified semi-volatile organic compounds not on the HSL.

The "Sample Data Summary Packages" corresponding to these analytical results have been previously submitted to the USEPA with the monthly analytical results summaries for the months of January, February, and March, and therefore have not been attached to this quarterly report.

PROGRESS ANTICIPATED FOR APRIL, MAY. AND JUNE 1990

The following progress is anticipated during the second quarter 1990:

• A site visit by Mr. Brother or Mr. Soukup to evaluate the field procedures and assure they are in accordance with the SAP.

• Completion of the RI field tasks.

• Initiation of the "Data Evaluation" and "Technology Screening" tasks of the RI/FS.

• Receipt and summarization of additional analytical results from UHL.

DATE: March 30, 1990

RE: QA/QC Audit - Des Moines South Area Source Control Project

6595

In late March 1990. Michael R. Brother. Project QA/QC Officer for ECKENFELDER INC.. conducted a QA/QC audit of the field investigation activities conducted to date for the Des Moines South Area Source Control Project. The items reviewed are summarized on Table 1. The audit included a review of all pertinent files and records for the work conducted to date. The results of the audit are described below.

Instrument Calibration

The Sampling and Analysis Plan (SAMP), calls for instrument calibration "in accordance with the manufacturer's instructions at the start of each day's use or [as] otherwise specified" and further notes that "(c)alibration procedures, frequency, and results will be recorded daily (emphasis added) in the field notebook". In a strict sense, these requirements are somewhat contradictory in that the manufacturer may specify other than daily calibration but the SAMP requires daily recording of the calibration.

With such an interpretation, calibration of the Century Systems OVA and the Y.S.I, conductance instruments could be considered to be out of compliance with the SAMP because it was not recorded on a daily basis. However, it is not believed that such an interpretation was the intent of the SAMP. Instead, the intent was to ensure that appropriate calibration of instruments occurred on a sufficient basis to ensure the quality of the data. The conductance meter, for example, was calibrated in the laboratory prior to shipment to the site and was used for only a short period of time during the groundwater and surface water sampling. Daily calibration of this instrument was therefore not necessary.

Similarly, calibration of the OVA was not conducted on a daily basis as the procedure is quite involved. Instead, the calibration was simply checked on a random basis during the investigation and calibrated as needed. For the remainder of the investigation, a weekly calibration check should be performed and documented. Lastly, the combustible gas/oxygen indicator was used for only a short period of time because of its poor performance in the difficult weather conditions encountered during the late Fall months. Upon the recommendation of Mr. Dan Myshrall, Corporate Director of Health and Safety for ECKENFELDER INC., the use of this instrument was discontinued and the question of

Memorandum to William G. Soukup March 30,1990 Page 2

calibration frequency is moot.

Field Data Sheets

Field data sheets for the groundwater and surface water samples were reviewed. At the time of the review, these records were incomplete. For example, required signatures were not present pnthe data sheets and several sheets were missing information regarding the well condition and/or purge data. Mr. Watkins indicated that these data were present in his field books and would be added to the Field Data Sheets. He also indicated that the signatures would be added.

Field Notebooks

The field log books maintained by the field geologist were reviewed by Mr. Brother. The descriptions were found to be thorough and accurate. In general, the field notebooks were also found to be clear, accurate, and legible. Nonetheless, several suggestions were made to improve the quality of the documentation as follows:

Indicate boring number and date on each page of the notebook to facilitate later review;

Include additional detail in the descriptions, e.g., sample density, moisture, stratification, mineralogy, etc., as warranted.

Chain-of-Custodv

Mr. Brother reviewed the Chain-of-Custody forms for the samples submitted to date and cross-checked these against the field notebooks and the Federal Express receipts for sample shipments. One Chain-of-Custody form (dated 12/13/89) was found to be missing an EPA Performance Evaluation sample that was actually contained in the shipment. No other discrepancies were noted.

HASP Compliance

No apparent discrepancies were noted in a review of the HASP documentation.

Sampling Procedures

No apparent discrepancies were noted in a review of the sampling documentation.

Distilled Water Blanks

The SAMP requires the collection of a single distilled water blank. To date, two such samples have been collected and analyzed.

Memorandum to William G. Soukup March 30, 1990 Pages

Duplicates & Blanks

The SAMP requires the collection of duplicates and rinsate blanks at the rate of one each for every nineteen samples per matrix. For the work conducted to date, such samples have been conducted at rates slightly less than required by the SAMP. Mr. Watkins was instructed to ensure that the remainder of the work will be conducted in full compliance with these requirements. Trip blanks have been collected as specified in the SAMP.

Analytical Results

The analytical results for the samples submitted thus far were also reviewed. The primary concern at this point is the presence of a number of unexpected compounds in the QA/QC samples. These compounds include those such as methylene chloride which can be attributed to low levels of laboratory interference. More problematic is the apparent occurrence of acetone, primarily in soil and sediment samples, at significant concentrations. Mr. Watkins is working with the laboratory to investigate the source of the acetone. Since it has not been detected in laboratory method blanks, the laboratory is probably not a factor. Its presence in at least some of the rinsate blanks suggests that field decontamination of sampling equipment must be considered. Mr. Watkins has been instructed to modify field decon procedures to allow for more time for air-drying between uses of the split-spoons and will attempt to obtain more split-spoons from the driller for use in the remainder of the project. Mr. Watkins and the laboratory are also investigating the possibility that a secondary source of 40ml vials could be associated with the presence^of acetone.
