INTRODUCTION

This Phase 4 project update memorandum has been prepared to briefly summarize and highlightresults of the Phase 4 remedial investigation (RI) at the former Ralston disposal (Ralston) site inCedar Rapids, Iowa. The Phase 4 activities outlined in the May 4, 1994 Phase 4 Addendum tothe April 1992 Field Sampling Plan (FSP) (Phase 4 FSP Addendum) focused on determining thehorizontal and vertical extent of volatile organic compound (VOC) contamination in the Siluriangroundwater system southeast of the Ralston site. The Phase 4 RI activities are distinguishedfrom the removal actions currently being implemented at the Ralston site. Whereas the removalactions are addressing the source area and contamination present above the bedrock surface, theRI is aimed at delineating the nature and extent of bedrock groundwater contamination at the site.

The specific objectives associated with the Phase 4 FSP Addendum were to:

1. Determine the horizontal and vertical extent of VOC contamination in the Silurianaquifer southeast of the Ralston site.

2. Delineate the Silurian stratigraphy southeast of the Ralston site for purposes ofidentifying zones of preferential groundwater flow and contaminant migration.

3. Define the potentiometric surface of the Silurian aquifer southeast of the Ralstonsite to determine the direction of groundwater flow downgradient of the site andpredict VOC migration pathways.

4. Establish a baseline for VOC concentrations in all site wells at the completion ofRI activities.

Ms. Susan Hoff September 23, 1994

The objectives of the Phase 4 RI have been met and the results are reported in this memorandum.It should be noted that some analytical results have not been validated and any conclusionsregarding this data should be considered preliminary pending receipt of validated data.

SUMMARY OF PHASE 4 REMEDIAL INVESTIGATION

In order to accomplish the objectives listed above, two additional monitoring wells (MW-9B,MW-9D) were installed southeast of the Ralston site. The locations of the newly installed wellsand all existing site wells are presented in Figure 1. A summary of the investigation activitiescompleted during the Phase 4 RI are summarized below:

• Monitoring well MW-9D was installed approximately 500 feet southeast of theRalston site (Figure 1). The purpose of this well was to delineate the verticalextent of VOC contamination in the Silurian aquifer downgradient of the site. Inthe Phase 4 Addendum, the well was intended to be an "E" well; however, basedon the results of coring and packer sampling at MW-9, the well was installed at adepth of 250 feet and designated as MW-9D. Coring and packer samplingactivities were conducted at MW-9 to a depth of 340 feet. This depth penetratedthe dense and cherty dolomite as required in the Phase 4 Addendum. Packersamples were collected from the MW-9 borehole at depths of 115 feet(corresponding to the typical "B" elevation), 180 feet (typical "C" elevation),250 feet (typical "D" elevation), 280 feet, 317 feet and 340 feet. A combination1-inch and 2-inch well was installed through the core rods with the well screen forMW-9D set at 243-253 feet and sand pack placed from 240-256 feet. The bottomof the borehole was sealed with a combination of bentonite grout, bentonite chipsand pea gravel. A monitoring well construction diagram for MW-9D is presentedin Figure 2.

• Monitoring well MW-9B was installed next to MW-9D at a depth of 113 feet(well screen set at 103-113 feet) to correspond to the other "B" wells at the site.The borehole was drilled to a depth of 119 feet using water rotary drillingmethods. Sand pack was placed around the 2-inch diameter well from a depth of98-113 feet with the lowermost portion of the borehole filled in rock chips fromdrilling activities. A monitoring well construction diagram for MW-9B ispresented in Figure 3.

• Dye was used during coring through the designated packer sampling intervals atMW-9 to evaluate the degree of purging necessary to remove the water lost to theformation during drilling. The results indicated that removal of the volume ofwater lost during drilling enabled collection of a groundwater sample representingapproximately 90 percent formation water and 10 percent drilling water. Thissampling ratio was suitable for the packer sampling activities.

• Dedicated QED bladder pumps were installed in all of the bedrock monitoringwells at the Ralston site following Phase 4 well installation activities. All of the


bedrock monitoring wells were subsequently sampled for VOCs during the weekof August 8-12, 1994. A Hydrolab multiprobe water analyzer was utilized tomonitor the water quality in-line from the sample pumps in order to micro-purgethe wells at low sampling rates.

• All of the alluvial and bedrock monitoring wells at the site and piezometerMW-6C were resurveyed by Brain Engineering, Inc. to account for new well capsplaced on the bedrock wells and provide a baseline elevation for all of the wellsmeasured to a common datum. Depth-to-water measurements were conducted atthe site on September 6, 1994.

SUMMARY OF PHASE 4 RESULTS

Geology

The general geology of Devonian and Silurian bedrock formations present at the site is discussedin detail in the Removal Site Evaluation Report and previous project update memorandums. Arock core log for MW-9 is presented in Attachment A and a graphic lithologic log is presented inFigure 4. This update summary will focus on the subsurface lithology delineated by MW-9 andprovide a summary of the current state of understanding of the bedrock geology in the sitevicinity. Cross sections of the Ralston site area as shown on Figure 5 are presented in Figures 6and?.

• A bedrock core was collected from MW-9 from a depth of 98-340 feet. Thestratigraphy encountered at MW-9 was generally similar to other site locations.Underlying a thick mantle of clayey glacial drift (loess and till), the bedrocksurface was encountered at a depth of 73 feet, placing the bedrock surface atnearly the same elevation as the disposal area of the site (Figure 6). TheDevonian Otis and Bertram Formations were observed to a depth ofapproximately 163 feet (elevation of 683 feet). One large void and severalsmaller voids were encountered in the Coggon Member of the Otis Formationbetween 105-115 feet below ground surface. Underlying the Bertram Formation,the undifferentiated Silurian Scotch Grove Formation was observed to a depth of325 feet. At this depth, the cherty dolomite of the Buck Creek Quarry Member ofthe Scotch Grove Formation was observed to the bottom of the borehole at340 feet (Figure 4). Several large voids were encountered during drilling throughthe Scotch Grove Formation at depths of 191-193 feet, 195-199 feet, 290-296 feetand 300-307 feet. Voids of this magnitude have not been encountered at otherdrilling sites in the area.

• The cross sections (Figures 6 and 7) indicate that the Devonian and Silurianformations at the site are relatively flat-lying and continuous throughout the area.The vugular porosity noted in the Coggon Member of the Otis Formation iscontinuous from MW-4 to the former Bauer well (MW-5D). At MW-9 this zone


exhibits a high degree of porosity, including a 3-foot void at the base of the unit(110-113 feet).

• The upper Scotch Grove Formation observed from the base of the Devonian to anelevation of about 610 feet is the most variable portion of the Silurian bedrock atthe site, varying from dense mudstone to highly fossiliferous and coarsecrystalline. Underlying this variable fades, at an elevation of approximately610 feet, the dolomite becomes more dense with highly developed and solutionenhanced interconnected vugular porosity. This vugular zone is remarkablyconsistent throughout the site vicinity and exhibits a thickness of about 60-70 feet.The "D" wells at the site are generally installed in this unit. Below this unit, theScotch Grove Formation becomes more fossiliferous and generally exhibits thevariable qualities of the uppermost layer. The Buck Creek Quarry Memberunderlies the undifferentiated dolomite and consists of dense and chertymudstone. The member appears to slope downward to the north, exhibiting a topelevation of 525 feet at MW-9 and 490 feet at MW-3E.

• A dense, blue-gray mudstone layer was encountered at MW-1 and MW-3. Theunit comprises a highly reduced portion of the Silurian aquifer, evidenced by theunit's reduced color, secondary pyrite formation and hydrogen sulfide odoremanating from MW-3C which is screened in this unit. The reason for this isunknown. This reduced mudstone layer has only been observed at MW-1 andMW-3 at elevations of 670 feet and 677 feet, respectively. The clayey silt andfossiliferous dolomite observed between the two large voids at 293 feet and305 feet also exhibit these reduced-type qualities.

Hydrogeology

The hydrogeology of the bedrock groundwater system was investigated during the Phase 4 RI.Groundwater elevations measured in all of the bedrock wells at the site on September 6, 1994 arereported in Table 1 and summarized below.

• The horizontal direction of groundwater flow in the Silurian Scotch GroveFormation is generally to the south at the Ralston site disposal area (Figure 8).The horizontal gradient in this area continues to be very low, which suggestspredominantly lateral flow in the aquifer. The groundwater elevation measured atMW-8D was lower than previous determinations and appears to indicate asouthwesterly component of groundwater flow south of the site. This direction isinconsistent with previous measurements. MW-6C continues to exhibit thehighest groundwater elevations in the site area.

• The estimated direction of groundwater flow in the Devonian System is presentedin Figure 9. The water level data from MW-1B suggests that a groundwater highexists in the vicinity of this well which results in lateral groundwater flow fromthe disposal area in both northeast and southeast directions (Figure 9). The


detection of contamination in Devonian wells located north (MW-2B, MW-3B)and southeast (MW-9B) of the site support this interpretation.

• The vertical groundwater flow system along cross-section trace A-A' (Figure 5) isconceptually illustrated in Figure 10. This cross section trace generally parallelsthe direction of bedrock groundwater flow north and south of the site.Groundwater flow from the source area is directed both laterally to the north inthe alluvium and downward into the Devonian and Silurian bedrock. The effectof the groundwater high present in MW-1B is illustrated in Figure 10, sincegroundwater is apparently directed toward both the MW-3 and MW-9 wells. Thedensely spaced potential lines between MW-1B and MW-1C suggest that theBertram Formation in this area restricts vertical groundwater flow directly beneaththe site. Elsewhere (e.g., MW-9), the Bertram Formation appears to provide littlebarrier to vertical groundwater flow between the Coggon Member and Silurianaquifer (Figure 10).

• Very little vertical gradient exists in the Scotch Grove Formation from the "C" to"D" wells (Figure 10). A slight upward gradient exists from the upper HopkintonFormation (MW-3E) to the Scotch Grove Formation (MW-3D).

• Groundwater elevations measured in alluvial monitoring wells and existingtemporary piezometers on September 6, 1994 are presented in Figure 11. Thedirection of groundwater flow in the alluvial aquifer is generally similar toprevious determinations. Flow from the source area is oriented in both northeastand northwest directions, with groundwater flow on the north side of Dry RunCreek directed toward the east-northeast (Figure 11).

Extent of Groundwater Contamination

Groundwater samples were collected from all of the bedrock monitoring wells at the site duringthe Phase 4 RI. In addition, packer samples were collected from MW-9 during drilling andcoring activities at this location. Packer sampling results are presented in Tables 2 and 3 andnonvalidated monitoring well analytical results and packer sample results are presented inTable 4. Analytical reports for the monitoring well samples collected during the Phase 4 RI areincluded in Attachment B.

• Six packer samples were collected at MW-9 during drilling activities to determinethe vertical extent of contamination southeast of the Ralston site. Packer sampleswere collected at depths of 115 feet, 180 feet, 250 feet, 280 feet, 317 feet and340 feet and analyzed by National Environmental Testing, Inc. (NET) in CedarFalls, Iowa for overnight laboratory analysis of target VOCs. Duplicate samplesfrom 250 feet and 350 feet were shipped to NET in Cambridge, Massachusetts forContract Laboratory Program (CLP) VOC analysis. The target VOC analyticalresults and validated CLP duplicate analytical results are presented in Tables 2and 3.


• Cis-l,2-dichloroethene (DCE) and trichloroethene (TCE) were detected in bothDevonian and Silurian groundwater packer samples (Table 2). DCE was found ata higher concentration in the Devonian sample corresponding to the "B" depth(115 feet) than the "C" and "D" samples (180 feet and 250 feet, respectively). Theconcentration of TCE was generally consistent from the "B" to "D" depths andranged from about 3 |ig/L to 6 |ig/L. Groundwater samples collected at 317 feetand 340 feet indicated little VOC contamination present, with DCE detected at2.8 (ig/L at 317 feet and estimated at a concentration of 0.5 |0.g/L at a depth of340 feet (Table 3). TCE was not detected at 317 feet and 340 feet. Vinyl chloridewas not detected in any packer samples. The analytical results from the packersamples suggest that the vertical limits of VOC contamination in the Silurianaquifer have been defined downgradient of the site.

• Nonvalidated CLP analytical results for monitoring well samples are summarizedin Table 4. At the MW-9 wells, the CLP results from monitoring well sampling atMW-9D are generally consistent with the packer results from the same depth.TCE and DCE were detected at MW-9D at 5 u,g/L and 12 u,g/L, respectively. Thelevel of TCE is equal to the maximum contaminant level (MCL) for thiscompound (5 |J.g/L) whereas DCE is significantly below (70 Jig/L).

• At MW-9B, the well sampling yielded higher concentrations of VOCs than thepacker results. TCE, DCE and vinyl chloride were detected in MW-9B at 5 (J.g/L,370 (ig/L and 4 fig/L, respectively. The concentrations of DCE and vinyl chlorideare above MCLs set for the compounds. The discrepancy between packersampling and well sampling is likely due to dilution of the packer sample duringdrilling. Although most of the volume of water lost during drilling the packerinterval of 105-115 feet was measured and removed during the dye study, thevolume of water lost above this interval was not evaluated. The results fromMW-9B indicate VOC migration southeast of the Ralston site in the DevonianCoggon Member. The detection of VOCs in Devonian groundwater south of thesite suggests that previous detections of VOCs at the Bauer well may have beenthe result of Devonian contamination and, possibly not Silurian, as previouslysuspected. Although the former Bauer well was cased through the large voids ofthe Coggon Member, packer samples collected above and below this zoneindicated VOC concentrations in the Devonian strata.

• Although most of the VOC levels detected in monitoring well samples at the siteappear to decline, a significant increase in VOC concentrations was observed inMW-3C (Table 2). The VOC concentration in this well appeared to increasenearly 1.5 orders of magnitude since July 1993 (800-1000 p.g/L with the Rockwellgas chromatograph). The reason for this large increase is unknown. Evidently,the dense mudstone of MW-3C has provided a barrier for vertical contaminantmigration since the level of VOCs in MW-3D has declined during this same time.


• In general, VOC concentrations in bedrock wells appear to have declined sinceprevious measurements although there continues to be variability betweensampling events. Table 5 presents the results of some target analytes detectedduring previous sampling events at the site. The concentration of VOCs atMW-3B and MW-3D have declined most significantly at the site (Table 5).

• The estimated extent of VOC contamination in the Devonian groundwater systemis presented in Figure 12. This delineation considers packer samples collected atthe former Bauer well and MW-7D to define the lateral limits of the plume. Theorientation of the plume is consistent with the southeastern direction ofgroundwater flow in the Devonian bedrock (Figure 9). Although the absolutelimits are not defined, the lack of VOC detections in the Finley well provide somemeasure of the extent of contamination.

• The estimated extent of VOC contamination in the Silurian Scotch GroveFormation is presented in Figure 13. The highest concentrations of VOCs in theSilurian aquifer are noted at MW-3C and the extent of this high level ofcontamination is estimated to be confined primarily to the limits of the site. Thelateral extent of VOC contamination appears to be defined to the east by MW-7Dand to the south by MW-5D. The low levels of VOCs detected in packer samplesand in MW-9D appear to signal the close proximity of the horizontal limits ofcontamination in the Silurian aquifer southeast of the Ralston site. Theconfiguration of the Silurian and Devonian plumes (Figures 12 and 13) appear tobe very similar, further indicating the highly related properties of the two aquifersystems.

• The estimated vertical distribution of VOCs in the bedrock groundwater systemdowngradient of the site (cross-section trace A-A1) is presented in Figure 14. Thefigure considers both packer and well sampling results, although it must be notedthat the well results provide more definitive information. VOC concentrationsappear to increase in the dense mudstone layer at MW-3C and above the denseand cherty Buck Creek Quarry Member at MW-3E (Figure 14). The verticaldistribution of VOCs appears to be consistent with the vertical flow systempresented in Figure 10. The higher levels of VOCs present in the MW-3 wellsmay be the result of increased vertical migration along fractures or solutionnetworks associated with the Dry Run Creek channel. Beyond the vicinity ofMW-3 and the creek channel, the concentrations of VOCs appear to decline bothvertically and horizontally at distance from the site.

CONCLUSIONS

• The Devonian and Silurian stratigraphy observed at MW-9 is similar to other welllocations at the site. The vuggy "D" zone and dense cherty dolomite appear torepresent correlatable units throughout the Ralston site area. Several large voidsencountered at MW-9 have not been previously noted at the site.


• The horizontal direction of groundwater flow in the Silurian aquifer at the Ralstonsite is generally to the south. A low groundwater elevation measured at MW-8Dsuggests a westward component of flow south of the site, although this remains tobe substantiated with repeated measurements.

• Groundwater flow in the Devonian bedrock at the Ralston site appears to bedirected both north toward MW-3 and south-southeast toward MW-9 around agroundwater high in the vicinity of MW-1B.

• The horizontal and vertical extent of VOC contamination in the Silurian aquifersoutheast of the Ralston site is defined by the packer and well sampling activitiesat MW-9. The extent of VOC contamination in the Silurian aquifer is bounded tothe east by MW-7D, south by MW-5D and southeast by MW-9D.

• VOC migration southeast of the site is occurring in the Devonian bedrock, mostlikely in the vuggy and cavernous Coggon Member. DCE and vinyl chloridewere detected in MW-9B above MCLs. The lateral limits of the Devonian plumeappear to be defined by packer samples at MW-5 and MW-7.

• Significantly higher concentrations of DCE and vinyl chloride were detected inMW-3C, compared with previous determinations. At other bedrock wells at theRalston site, the levels of VOCs in the wells were generally observed to decline.

TABLESVOLATILES ORGANICS NARRATIVE SUMMARY

FD1203

GENERAL COMMENTS: The samples were analyzed using a modifiedmethod OLM01.9 with a 25 ml purge for lower detection limits.

The Client requested the laboratory to verify results for sampleMW3C (NET ID 108177) as preliminary results did not matchprevious sample history. Several dilutions had been analyzed andresults were consistent. The sample vials were checked forsample ID and everything appears to be correct.MANUAL INTEGRATIONS: Manual integrations are performed onstandards and samples when the integration is not complete due topeak shape and chromatography. This is confirmed by visualinspection by the analysts. The "M" flag indicates that a manualintegration has been performed.

#17- Total 1,2-Dichloroethene must be integrated in the initialand continuing calibration standards to include the total area ofthe cis- and trans- isomers.SURROGATES: All system monitoring compound I recoveries werewithin the contract required QC limits.MATRIX SPIKE/MATRIX SPIKE DUPLICATE(s): All spike recoverieswere within QC limits for the MS/MSD analysis. All RPDs werewithin the required limits.BLANKS: A method blank was analyzed for each twelve hour timeperiod on each GC/MS system used for analysis. No blankcontained greater than five times the CRQL of Methylene Chloride,Acetone, and 2-Butanone, or greater than or equal to the CRQL ofany other volatile target compound.TUNE: All instrument performance check criteria were met priorto the start of sample analysis.

CALIBRATION: All compounds met the required minimum RF's andmaximum RPD's or %D.

ORGANIC FLAGS AND SAMPLE SUFFIXES

The following qualifiers have been used for reporting results:

B - The "B" flag indicates that the analyte was found in theassociated blank as well as in the sample.

E - The "E" flag indentifies compound concentrations that exceedthe calibration range of the GC/MS instrument. For Benzo (b)and Benzo (k) Flouranthene, the calibration range of eachpeak will be considered separately. Ortho, para, and metaxylene are quantified as two peaks, the calibration range ofeach peak will be considered separately.

D - If a sample is re-analyzed due to high concentrations andboth the original analysis and re-analysis have beenreported, the diluted analysis will have the "DL" suffix.All concentration values reported for the diluted analysiswill be flagged with a "D".

U - The "U" flag indicates that the compound was analyzed for butnot detected. The reported "U" value is the detection limitfor the given compound. The value is corrected fordilution and for percent moisture.

J - The "J" flag indicates an estimated value. The flag is usedfor tentatively identified compounds where a 1:1 response isassumed, or when the mass spectral or chromatographic dataindicate the presence of a compound that meets theidentification criteria but the guantitated value is lessthan the method quantitation limit.

P - The "P" flag indicates that the quantitated value of atarget pesticide/PCB differs by more than 25% on the two GCcolumns that were reported.

Y - Compound values that are flagged with a "Y" have been editedon our RTE/MS data system.

X - Compound values that are flagged with a "X" have been editedon our Foremaster data reporting system.

C - This flag applies to pesticide or GC parameters where theidentification has been confirmed by GC/MS.

The following sample suffixes have been used:

XXXXX = sample numberXXXXXMS = matrix spike sampleXXXXXMSD = matrix spike duplicate sampleXXXXXRE = re-analyzed sampleXXXXXDL = sample analyzed at a secondary dilution inn

FD1203

GENERAL COMMENTS: The samples were analyzed using a modifiedmethod OLM01.9 with a 25 ml purge for lower detection limits.

The Client requested the laboratory to verify results for sampleMW3C (NET ID 108177) as preliminary results did not matchprevious sample history. Several dilutions had been analyzed andresults were consistant. The sample vials were checked forsample ID and everything appears to be correct.MANUAL INTEGRATIONS: Manual integrations are performed onstandards and samples when the integration is not complete due topeak shape and chromatography. This is confirmed by visualinspection by the analysts. The "M" flag indicates that a manualintegration has been performed.#17- Total 1,2-Dichloroethene must be integrated in the initialand continuing calibration standards to include the total area ofthe cis- and trans- isomers.SURROGATES: All system monitoring compound recoveries werewithin the contract required QC limits.MATRIX SPIKE/MATRIX SPIKE DUPLICATE(s): All spike recoverieswere within QC limits for the MS/MSD analysis. All RPDs werewithin the required limits.

BLANKS: A method blank was analyzed for each twelve hour timeperiod on each GC/MS system used for analysis. No blankcontained greater than five times the CRQL of Methylene Chloride,Acetone, and 2-Butanone, or greater than or equal to the CRQL ofany other volatile target compound. j

TUNE: All instrument performance check criteria were met priorto the start of sample analysis. >

CALIBRATION: All compounds met the required minimum RF's andmaximum RPD's or %D.

INTERNAL STANDARDS: All internal standard areas andtimes were within the QC limits.
