SUMMARY TEST REPORTFOR LEMON LANE DYE TESTING

Summary of July - November 2002 Dye Tracing JcMUBry 2003

1.0 Introduction

1.1 Indications from Previous Traces

Dye tracing in October-November 2001 indicated that the phreatic zone in theValhalla area might travel east towards the 4-series wells. The injections in LF-6-8" indicated that the epikarst in the southeast corner of Lemon Lane may travelsouthwest into Valhalla. Both injections were detected in well OO-370 inValhalla. What was left unclear was whether there was another major phreaticpathway out of Valhalla to 1C spring or whether the major phreatic pathway wasback towards the east side of Lemon Lane as the low flow phreatic water levelssuggested. The lack of coincident timing of the storm tracer pulse from LF-6-4"and the PCB pulse at 1C spring indicated that the timing of injected tracer pulseswould be a good indication of where the immediate source of the high PCB pulsemight or might not be. Dye was introduced into LF-6-4" just prior to a rain event.The first rain event was small and did not move any tracer from the location.Two storms of greater magnitude followed shortly thereafter and produced dyebreakthrough curves at 1C spring. But there was a 5 and 6 hour delay,respectively, between the PCB arrival time and the dye arrival time. Based onthose results, it was hypothesized that tracer travel times that matched the timespredicted by the regression analysis of PCB pulse arrival times might indicate thesource location(s) of the high PCB pulse.

1.2 Reasons for Conducting Tracing

The reasons for conducting these series of traces fall into three categories.• Induction of PCB response• Comparison of travel times• Detection of site pathways

Viacom has constructed a relationship between flow rate at 1C spring and thetime of arrival of the high concentration PCB pulse during storm events. Thatrelationship is an exponential function which has been empirically derived fromat least 21 storm events over a range of rainfalls and is:

Travel Time in hours =1211.3 (1C flow in gpm)"08591

Although this is a storm derived relationship, we believe that a tracer injectionlocation would be a candidate for the high PCB source area only if the timing ofthat tracer pulse will match that of the derived equation. If there is a significantlag time between tracer arrival and calculated PCB arrival time then we mightpresume that location is not a significant contributor to the high PCB storm pulse.Such a situation seemed to be the case in the aforementioned LF-6-4" trace.

It was also reasoned that various epikarst locations could be flushed with waterand tagged with tracer. If a PCB pulse could be induced at 1C spring arrivingcoincident with the injected tracer, then this might reveal possible sourcelocations.

The third reason for tracing was to discern pathways around the site. Thisinvolved sampling other monitoring wells after tracer injection and trying todiscern downgradient from upgradient locations. This was not always apparentfrom water levels and potentiometric surface interpretations, especially since thephreatic gradient was so flat.

2.0 Description and Results of Traces

A general summary of the dye traces is given in Table 1. The first column showsthe date and time of dye injection. The second column shows which dye, eitherRhodamine WT (RWT) or Fluorescein (FLR) was injected. First detection refersto the first sample location the dye was detected, and the hours from injectionthat the first sample was taken that had the dye positively detected. The fifthcolumn is the date and time of first dye arrival at Illinois Central Emergence andthe next column shows that first arrival time in hours. The seventh column is theaverage flow rate at 1C spring between dye injection and first detection at thespring. The eighth column is the travel time predicted by the empirical equationderived from the PCB storm pulses. The last column is the percentage of themass of dye recovered at the spring. Tables 2-10 show the results of all thetraces at the various sample locations.

2.1 MW-4i and MW-6 Tracer Test

The scope of work for conducting the MW6-MW4I low flow trace is contained inAttachment 1. The trace was designed to compare travel times to the 1C springin order to evaluate whether MW6 is on an upgradient pathway from MW4i or ison a separate but similar pathway to the spring. MW4i was injected with 225grams of Rhodamine WT (Cl Acid Red 388) at 12:45 on 7/10/02. MW6 wasinjected with 50 grams of Fluorescein (Cl Acid Yellow 73) at 13:10 on 7/10/02.The injections were accomplished through an aluminum tube with the outlet setat the 799' elevation. Each well was flushed with 30 gal. of water. Monitoringwells OO-587, NN-300, OO-300, OO-370, OO-125, and NN-12 were sampledtwice daily. Quarry B spring and Slaughterhouse spring were sampled twicedaily and Illinois Central was sampled with an auto sampler. The monitoringwells were sampled until 7/12. The springs were sampled through the next tracerinjection of 8/6/02.

The RWT injected in MW4i was not detected in any other monitored well, but wasdetected beginning 7/11/02 18:30 hours at 1C spring. The RWT rose to a peak of636 ppb on 7/12/02 02:30 hours and returned to around pre-injection backgroundlevels sometime on the morning of 7/24. The mass recovered was about 53% of

injected. The first arrival time of 29.75 hours is close to the 27.2 hours predictedby the PCB storm pulse regression analysis.

The FLR injected in MW6 was detected on the 7/11 11:00 hr. sample from NN-300. The dye was not detected in any other well or spring, with the possibleexception of MW4i on a 7/31 sample. This dye was not detected at 1C springdespite a 0.95" rain on 7/9, a 1.07" rain on 7/23, and a 0.46" rain on 7/29. Figure1 shows a plot of the RWT and FLR at 1C spring for the first week after injectionwith the RWT concentration on the left scale from 0-700 ppb and the FLRconcentration on the right scale from 0-7 ppb and indicate the magnitude ofdifference of tracer detection of the two injection locations at the spring.

2.2 PZ-F Trace

The scope of work for conducting the PZ-F trace is contained in Attachment 2.The goal of this test was to see if a PCB spike could be .induced and if the traveltime to the spring was indicative of the PCB storm pulse travel time. 1000gallons of water was to be flushed to induce this pulse. After 300 gallons hadbeen flushed, 225 grams of RWT was injected and the rest of the 700 gallons ofwater was flushed. The dye was poured in at the top. Previous slug testingindicated water exiting major fractures or conduits at elevations 851' and 828'.Time of dye injection was 8/6/02 at 10:00 hours. The following wells were to besampled 4 hours after the flush and then daily: NN-412, NN-300A, OO-300A,OO-370, and MW-4L Well NN-300A had too little water in the bottom of the wellto get a sample and well NN-412 was completely dry. 1C spring was sampledwith an auto sampler.

The tracer was detected in OO-300A and OO-370 on the first sample afterinjection. Although that sample was 5.75 hours after injection, there was visibledye in both wells indicating the dye was there before the sample was taken. Thetracer was not detected at well MW-4i. The tracer first appeared at 1C spring on8/8 at 20:00 hours, 58 hours after injection. This compared well with thepredicted travel time of 58.6 hours based on the storm PCB regression. The dyepeaked at 284 ppb on 8/8 13:00 hours and receded to background sometime on8/22. Approximately 35% of the mass injected was recovered at 1C spring.Table 11 shows the PCB results at 1C spring. Figure 2 shows the plot of theRWT breakthrough curve and the PCBs, and indicates little, if any, PCBresponse induced by the flush.

2.3 NN-300A Trace

The scope of work for conducting the NN-300A trace is contained in Attachment3. The goal of this test was to see if a PCB spike could be induced and if thetravel time to the spring was indicative of the PCB storm pulse travel time. 1000gallons of water was to be flushed to induce this pulse. After 300 gallons hadbeen flushed, 225 grams of RWT was injected and the rest of the 700 gallons of

water was flushed. The dye was poured in at the top. Time of dye injection was8/20/02 at 09:15 hours. The following wells were to be sampled 4 hours after theflush and then daily: NN-300, OO-300A, OO-387, MW-6, OO-370, and MW-4L1C spring was sampled with an auto sampler.

The tracer was detected in OO-370 on the first sample taken 30 minutes afterinjection. The tracer was detected in NN-300 and OO-300A in the first samplestaken after injection. The tracer was not detected at wells MW-6, OO-387, orMW-4i. The tracer first appeared at 1C spring on 8/23 at 16:00 hours, 79 hoursafter injection. This was much longer than the predicted travel time of 54.5 hoursbased on the storm PCB regression. The dye peaked at 8.2 ppb on 8/24 07:00hours and sampling was discontinued on 8/24 before the tracer receded tobackground. Approximately 4% of the mass injected was recovered at 1C spring.Table 12 shows the PCB results at 1C spring and indicates little, if any, PCBresponse induced by the flush.

Figure 3 shows a plot of the RWT breakthrough curves for both the PZ-F traceand the NN-300A trace. The time scale is in days from dye injection. The leftscale shows the RWT concentration at 1C spring from the PZ-F flush and theright scale shows the RWT concentration at 1C spring from the NN-300A flushand is 1/10 the scale. Note that PZ-F is only 70' north of NN-300A.

2.4MW16-MW18Trace

The scope of work for the MW16-MW18 trace is contained in Attachment 4. Thegoal of the trace was to compare arrival times from each well to 1C spring. Lowflow water levels taken at phreatic wells around the site would sometimes showMW16 as a local low and it was wondered whether there was a separate path tothe spring from this area of the site. MW18 was injected with 225 grams ofRhodamine WT (Cl Acid Red 388) at 13:15 on -10/1/02. MW16 was injected with50 grams of Fluorescein (Cl Acid Yellow 73) at 14:00 on 10/1/02. The injectionswere accomplished through an aluminum tube with the outlet set at the 799'elevation. Each well was flushed with 30 gal. of water. Monitoring wells MW4i,MW19, and MW15 were sampled twice daily. Quarry springs combined andSlaughterhouse spring were sampled twice daily and Illinois Central wassampled with an auto sampler. The monitoring wells were sampled until 10/3.The springs were sampled through 10/5 at 09:00.

The RWT from MW18 was detected in MW4i in the first sample taken afterinjection within 3.25 hours. The first detection of the RWT at 1C spring was 10/2at 20:00 hours or 30.75 hours after injection which compares to 26.6 hours aspredicted by the storm PCB regression. The RWT peaked at 398 ppb on 10/3 at04:00 hours and about 60% of the mass was recovered.

The FLR from MW16 was present in MW4i and MW19 on the morning sample ofthose wells on 10/2, about 18.5 hours later. The first occurrence of the FLR at 1C

spring was 10/3 at 12:00 hours or 46 hours after injection as compared to apredicted travel time of 27.2 hours based on the PCB storm regression. The FLRpeaked at 15.84 ppb on 10/4 at 01:00 hours and about 27% of the mass wasrecovered by the time sampling ceased on 10/5. Figure 4 is a plot of thebreakthrough curves for the respective dyes. Notice the right scale for the FLR is1 /10 the scale for the RWT.

2.5 MW6-OO370 Trace

The scope of work for the MW6-OO370 trace is contained in Attachment 5. Nodiscemable break through curve was seen at 1C spring the last time MW6 wasflushed. Several dye traces have had intermediate detections in OO370. Thegoals of this test were:

• Increase the dye amount injected to produce a breakthrough curve at 1Cspring so travel times could be compared to the PCB storm regression.

• Determine if lack of detection at 1C spring was because dye traveled toother springs.

• See if site pathways led back to the 4-series area.

MW6 was injected with 250 grams of Fluorescein (Cl Acid Yellow 73) at 09:15on 10/22/02. OO370 was injected with 450 grams of Rhodamine WT (Cl AcidRed 388) at 10:00 on 10/22/02.The injections were accomplished through analuminum tube with the outlet set at the 799' elevation. Each well was flushedwith 30 gal. of water. Monitoring wells MW4i, MW4s, MW20, MW-10, MW18,MW19, MW16, and MW15 were sampled twice daily on the eastside of LemonLane. OO587, NN625, OO387, NN300, OO300, OO125, and NN12 weresampled twice daily in Valhalla. Quarry springs combined, Detmer, Snoddy-Hinkle combined, Bypass 37, Urban, Crestmont and Slaughterhouse spring weresampled twice daily. Both Illinois Central and Stony East spring were sampledwith an auto sampler. Stony West began by being sampled twice daily, and laterin the test (beginning on 10/30 16:00) an auto sampler was added there as well.The monitoring wells were sampled until 11/8. The springs were sampledthrough 11/8 also.

The RWT from OO370 was first detected in MW18 in the sample taken 24 hoursafter injection at 10/23 10:50. It was then detected in MW20 on the 10/23 14:18sample. Figure 5 shows the RWT concentration in the east side wells. Note thatthe Y-axis is log scale. Although reaching concentrations in well MW18 as highas 19,490 ppb, the RWT was never conclusively detected in any springsincluding 1C spring.

The FLR from MW6 was present in MW4i and MW20 on the morning sample ofthose wells on 10/30, about 190.5 hours after injection, but only at 18.82 and12.27 ppb respectively. There was 42.09 ppb detected in the 10/30 07:48sample in MW4s. Figure 6 show the FLR concentration in the east side wells.There was no conclusive detection of FLR at any spring including 1C spring.

3.0 Discussion

3.1 Induction of PCB Response

The idea of the induction of a PCB response was based on the premise thatflooding a location with water tagged with tracer would force pockets of highPCBs into the phreatic conduits. PCBs in these locations would normally beflushed out during storm events. By forcing them out during non-storm eventswe could selectively measure the possible contribution from the flushedlocations. The travel times would correspond to those calculated from the PCBstorm regression equation.

However, neither the flush test of LF-6-8" in April, nor the flush test of PZ-F orNN-300A produced any significant PCB response at 1C spring. Whether thismeans that the locations themselves are not contributors to the high PCB stormpulse, or the low flow flushing does not adequately simulate a storm event is notcompletely clear. Response in phreatic wells to flushing PZ-F and NN-300A wasnearly instantaneous, as shown on Figures 7-9, which may indicate that thewater, rather than flushing the epikarst around the borehole, descended straightinto the phreatic zone.

3.2 Comparison of Travel Times

There seem to be three categories of traces with regard to travel time from thesite to 1C spring. They would be:

• Those tracer injections which are never detected.• Tracer travel times significantly longer than predicted.• Tracer travel times comparable to that predicted by the empirically

derived equation based on high PCB storm pulses.

Within the first category would be:1. The October 2001 injection of Phloxine B into SP-1.2. The October 2001 injection of Eosine into NN-700.3. The July 2002 injection of Fluorescein into MW-6.4. The October 2002 injection of Fluorescein into MW-6.5. The October 2002 injection of Rhodamine WT into OO-370.

The second category would contain:1. The May 1996 injection of RWT into North Sink.2. The October 2001 injection of FLR into LF-6-8".3. The May 2002 injection of FLR into LF-6-4".4. The August 2002 injection of RWT into NN-300A.5. The October 2002 injection of FLR into MW-16.

The third category would contain:1. The May 1996 injection of FLR into MW-7 area macropores.2. The April 2002 injection of FLR into LF-6-8".3. The July 2002 injection of RWT into MW-4L4. The August 2002 injection of RWT into PZ-F.5. The October 2002 injections of RWT into MW-18.

Our interpretation, at the present time, is that these categories representhierarchal organization within the Illinois Central Spring basin karst conduitbranchwork and the proximity or open connection of the injection location to amajor tributary conduit. Traces that never produce break through curves at thespring represent areas that are not drained by major phreatic tributaries, perhapsbecause they are at the "upper reach" of the drainage basin. The "upper reach"aspect may area-related, that is, far away in distance, or vertical-related, in thatthe vadose segments may not be fed by significant recharge. They may alsotake long, tortuous pathways so that dye concentrations are longitudinallydispersed by the time they reach the spring. Another possibility, of anastomoticflood mazes, is discussed in Palmer (1991) (Palmer, Arthur N., 1991, Origin andMorphology of Limestone Caves, Geological Society of America Bulletin, v.103,p. 1-21.). This refers to a conduit collapse or blockage which results in floodwaters dissolving an anastomotic maze around the blockage. Palmer cites BlueSprings Cavern in Indiana as an example. The dye disperses in the maze toconcentrations not detectable at the spring.

Tracer travel times that are significantly longer than predicted by the PCB stormpulse regression represent locations that are "farther" from the spring, forexample - North Sink, in terms of length of phreatic conduit. Another aspect of"distance" may also be lateral travel in the vadose zone. This may explain whythe October 2001 injection of FLR into LF-6-8" and the storm injection of FLR inLF-6-4" of May 2002 took longer than the April 2002 injection of FLR into LF-6-8".The difference in those injections was the amount of flushing water - 1032gallons for the April 2002 trace. This above normal amount of water may haveflushed the dye into a shorter pathway than it would have normally taken.However, since the volume of water altered the travel time results, caution shouldbe exercised in extrapolating the results of these non-storm dye tests to stormconditions.

Locations where the tracer travel times match the PCB storm pulse are candidatelocations for investigation as possible source areas for the PCB storm pulse. Itmay be instructive to note that tracer locations in Valhalla have either producedno break through curves or delayed passage to the spring. Refer back to Figure3 - Comparison of Breakthrough Curves for PZ-F and NN-300A Traces as anillustration. This implies that the high PCB pulse does not originate in theValhalla area, but lies north of the tracks under the Lemon Lane site itself.

3.3 Detection of Site Pathways

It is puzzling why there is a lack of tracer detection at 1C spring from MW6 andwhy the OO370 trace would show up in MW18 at concentrations as high as19,400 ppb but not produce a break through curve at the spring. It is probablynecessary to repeat this trace. Nevertheless, a pattern does emerge as shownon Figure 10, which is a summary of the tracer detections in the wells around thesite. Although some traces were detected in well OO370, that well wasconclusively traced to MW18. From a simple "connect the dots" perspective, itseems apparent that the near site flow directions are from west to east andtowards the 4 series wells. This would imply that a major collector tributaryconduit exists along the east side of Lemon Lane, possibly just east or north ofthe 4-series wells. We suspect most of the near-site drainage, and in particularhigh PCB source areas, converges toward this junction before being conveyed to1C spring.

Scope of Work for MW6-MW4I Low Flow Tracer Test

Goal of the Test:

Compare arrival times of dye from MW-6 area and the MW4I area to 1C Spring.This might elucidate whether a pathway from MW-6 is truly upgradient fromMW4I as suggested by the phreatic water levels, or is on a separate pathway tothe spring. If dye from MW4I arrives significantly before dye from MW-6 then alonger pathway (upgradient) from MW-6 may be inferred. If dyes arrive nearlysimultaneously, or MW-6 dye precedes MW4I dye, then separate flow paths areinferred.

Set up and Preparation

• Prepare 50 gram injection aliquot of fluorescein.• Prepare 225 gram injection aliquot of Rhodamine WT.• Prepare standards for fluorometer.• Take daily dye background samples at 1C spring.• Take background samples of OO-587, NN-300, OO-300, OO-370, OO-

125, and NN-12.• Take background samples of Quarry and Slaughterhouse springs.• Set up ISCO samplers sampling for dye at 1C spring.• Stage 30 gal. of clean water at MW-6 and MW4I for flushing.• Stage flexible aluminum injections tubes in MW-6 and MW4I for injection.

End of the tubes should be at the 799' elevation in each well.

Dve Injection

• Monitor weather and schedule test for 3-day dry period.• Set up peristaltic pump at each well.• Simultaneously inject fluorescein into MW4I and Rhodamine WT into MW-

6.• Flush each well synchronously with 30 gal. of clean water.

Field Sampling

• Set ISCO auto samplers to begin sampling two hours before dye injection.• Set sample frequency to alternating two hourly samples (1 hour

coverage).• Obtain 1C spring flows and calculate estimated travel time. Samplers

should run for twice the estimated sample travel time, or untilbreakthrough curves for both dyes are established.

• Sample injection wells right after flushing, once at 8 hours after injection,and once more 20-24 hours after injection.

• Sample OO-587, NN-300, OO-300, OO-370, OO-125, and NN-12 twicedaily.

• Sample Quarry and Slaughterhouse springs twice daily,

Dye Analysis

• Dye samples are taken to office warehouse and refrigerated.• Dye samples are prepared for dye analysis according to SOP and dye

analysis is performed with fluorometer.• Dye results are plotted and decision is made whether sufficient

breakthrough data are obtained. If no dye is seen within twice theestimated travel time, sampling will continue for two more days on every 2hour interval.

General Scope of Work for Flush Tests

Goals of the Test:

• Flush tracer from various epikarst locations. Determine if flushed waterinduces a dye and PCB response at 1C spring.

• Determine if the dye and or PCB response at the spring matches traveltimes for PCB peaks during storms. A PCB response at the spring will beindicative that the flushing water contacted a significant PCB source area.The dye travel time will be indicative of the relation of the flushed pathwayto that taken by PCBs during storm events.

• Locations to be flushed may include, but are not limited to: NN-300A, NN-412, PZ-E, PZ-F, and Martins Sink. Additional shallow boreholes may beplaced in the landfill southeast corner to serve as flush locations. If theyare placed, the placement will be based on top or rock contours andexisting geophysics.


• Review weather and ensure no rain predicted for the test period (until atleast 12 hours after predicted dye arrival time). Note; the test is also notto be done immediately after a large storm event. Spring flow at 1C Springshould generally be less than 300 gpm before starting the test.

• Check location for presence of free product, and remove free product ifnecessary.

• Obtain flow from 1C STF to estimate travel times. ^*H3ft9• Place additional dataloggers in nearest phreatic well (dataloggers already

in MW-21 and MW-6). On morning of test set logging interval to 5minutes.

• Take confirming hand water level measurements.• Take background fluorescent samples at 1C Spring.• Set up flushing water tank on back of truck with discharge line near

location to be flushed. AVV0• Start auto samplers at Illinois Central Spring on hourly intervaL

Flush Test

Analyze all samples on field fluorometer. Submit peak dye sample atspring plus sample on either side for analysis on SSFP. These will beused as a correction factor for the filter fluorometer concentrations.Analyze two samples on either side of dye peak at spring for PCBs (totalof 5 samples). Extract all other 1C Spring PCB samples and hold extractuntil PCB results from the first 5 analyzed are obtained. Determine ifadditional 1C Spring PCB samples should be completely analyzed.Download dataloggers on morning of next day after flood test and returninterval to hourly.Download dataloggers one week after test and remove additionaldataloggers.

Flush Test

• Begin flushing water and adjust inflow rate so water does not back up inriser. Calculate flow rate into aquifer.

• If flow rate is 10 gpm or better, flush 300 gallons, add 225 gramsRhodamine WT, and flush 700 gallons. If flow rate is less than 10 gpmthen 500 gallons total will be flushed.

After flushing, check for visible dye, take a sample and run on thefluorometer, and determine if additional water needs to be flushed. It isdesired to have no visible dye left in location after the flush.Continue auto samplers at spring for (7 hours) + (calculated time of travelbased on spring flow) + (additional 24 hours), or until breakthrough curveis determined to be sufficient or, if dye does not appear at 1C spring, thentwo days after calculated arrival time.Sample well 4 hours after flushing, and then daily until dye breakthroughcurve is confirmed at spring.Once dye breakthrough curve is confirmed at spring sampling frequencycan be increased to 4 hours for a day and then 8 hours thereafter.Analyze all samples on field fluorometer.
