1.0 EXECUTIVE SUMMARY

This plan for the Creek Realignment Project (the "Project") has beenprepared as a Time Critical Action at Third Site, located north ofZionsville, Indiana. Third Site is located approximately 300 feet south ofthe Enviro-Chem Corporation (ECC) Superfund Site on a bend in FinleyCreek between an artificial pond (Bankert's Pond) and the creek(Figure 1).

1.1 BACKGROUND

Between 1987 and 1990, field investigations of Third Site wereconducted by ERM-North Central, on behalf of the ECC PotentiallyResponsible Parties, and CH2M Hill, on behalf of the U.S. EnvironmentalProtection Agency (USEPA). The results of the soil and ground waterinvestigations indicate that Third Site consists of the area shownapproximately on Figure 1, and that the primary significant chemicalconstituents are chlorinated volatile organic compounds (VOXs) asdiscussed in Section 2.3 of this document. The extent of the VOXs, ifany, in the soil under Bankert's Pond is unknown.

1.2 SCOPE AND OBJECTIVES

The objective of the proposed Project to be conducted at Third Site is tosignificantly reduce the risk of a sudden discharge of VOXs to FinleyCreek. This will be accomplished by realigning the "oxbow" bendportion of Finley Creek that is presently adjacent to Third Site so as toshift the creek channel approximately 40 feet away from soils containingVOXs.

This project consists of realigning the "oxbow" bend in Finley Creekadjacent to Third Site. This Project is being undertaken as a TimeCritical Action because of the following conditions:

• There exists the potential for contamination of drinking watersupplies;

• There are VOXs in the soils at Third Site at or near the surfacethat may migrate;

• There are weather conditions such as spring rains andaccompanying high flows in Finley Creek that may cause VOXsto be suddenly released to Finley Creek through rapid erosionand/or a breach of the berm; and

ERM-ENVIROCLEAN-NORTH CENTRAL. INC. I CREEK REALIGNMENT PROJECT

• Finley Creek feeds the Eagle Creek Reservoir, which is source ofdrinking water to the City of Indianapolis.

As a Time Critical Action, the Project should begin as soon as possibleto reduce the immediate threat to public health and the environment.

ERM-ENVIROCLEAN-NORTH CENTRAL, INC. / CREEK REALIGNMENT PROJECT

2.0 SITE CHARACTERIZATION

This section summarizes the available geological and chemicalinformation for Third Site, obtained from the following reports:

• CH2M Hill, Technical Memorandum No. 2, September 16, 1988.

• ERM-North Central, So/7 Boring Investigation, Vicinity of FinleyCreek, August 21, 1987.

• ERM-North Central, Third Site, Ground Water Sample Results, July1992.

• ERM-North Central, Third Site, Investigation of Fishing Pond, April1990.

2.1 SITE DESCRIPTION AND HISTORICAL LAND USE

Third Site is located north of Zionsville, Indiana, about 10 milesnorthwest of Indianapolis, 300 feet south of the ECC Superfund Site,and some 350 to 400 feet southwest of the Northside Sanitary LandfillSuperfund Site. The Site is within the Rosston, Boone County, Indiana,U.S. Geological Survey topographic map quadrangle.

ERM-North Central conducted a review of the historical land use ofThird Site area by examining aerial photographs, dated from 1950 to1986. The results of this historical aerial photograph review aresummarized in a September 21, 1987, letter to USEPA. As illustrated onFigure 2, portions of the area were used for truck parking and tank anddrum storage during in the middle to late 1970s. A portion of the areato the north of Third Site was developed as a fishing pond after May 3,1986 (i.e., the date of the most recent aerial photograph available at thetime of the review). According to the property owners, the pond wascreated by excavating materials from the area to depths of up to 15 feetand using those materials to build a berm around the southwestern,southern, and southeastern sides of the pond and to regrade the areabetween the pond and Finley Creek. These excavation activities appearto have concentrated the VOXs into the berm and regraded areas. TheVOXs were apparently associated with the activities described above.

Third Site is estimated to cover an 0.6 acres. An unpaved roadwayprovides construction access to the area. The nearest residence is the

resident located approximately 220 feet to the north, northwestof the western Third Site boundary.

2.2 GEOLOGY

The subsurface geologic setting in the Third Site area is complicated dueto the depositional history as well as the excavation and earth movingthat led to the creation of the fishing pond. Soil borings were drilled atthe site by ERM-North Central in 1987 and are identified as "SB"locations as shown in Figure 3. USEPA drilled a series of borings in1988, which covered the area between ECC and Third Site as shown inFigure 4.

In general, the surficial materials consist of up to 10 feet of fill with ahigh clay content overlying a discontinuous clay till or alluvium.Several sand lenses within this upper alluvial unit were not fullypenetrated during the advancement of the soil borings (i.e., at soilborings Nos. 4, 5, 9, 10, and 11). However, the sand or sand and gravelappear to be discontinuous lenses within the alluvium. Also, a sandand gravel unit of variable thickness underlies the alluvium. Becausethis sand and gravel unit varies both in color and apparent composition,it is likely an admixture of sands derived from glacial outwash andsands deposited by more recent alluvial processes associated with theFinley Creek drainage system.

The deepest unit penetrated in any of the soil borings in the vicinity ofThird Site is a clayey, dense silt till encountered at a maximum depth ofapproximately 20 to 30 feet. Although this lower till was not penetratedto determine its total thickness, the density and dryness of samplescollected from this unit are indicative of low permeability. Therefore,any downward migration of ground water would be effectively limitedby this layer.

The water level in Bankert's Pond is approximately 6 feet above theaverage water level in Finley Creek. The higher water level in the pondcreates a significant head difference between Bankert's Pond and FinleyCreek, which increases the potential for discharge of VOXs to FinleyCreek. The head difference between the pond and the underlying sandand gravel layers and Finley Creek causes any water flow to be fromthe pond to the sand and gravel layers, and then into Finley Creek.

2.3 NATURE AND EXTENT OF VOXs

The nature and extent of VOXs at the site was determined by evaluatingdata collected by:

• ERM-North Central in 1987, which includes field screening resultsfor VOXs, and laboratory analytical data for soil, ground water,seepage soil, and seepage water samples.

ERM-ENVIROCLEAN-NORTH CENTRAL. INC '* CREEK REALIGNMENT PROJECT

CH2M Hill in 1988, which included laboratory analytical resultsfor soil and ground water samples.

ERM-North Central in 1992, which included samples of groundwater that were split with Ecology and Environment. Theanalytical results for VOXs, semivolatile organic compounds(SVOCs), and inorganics are discussed in the followingsubsections.

2.3.1 VOX Distribution

Based on field screening results obtained for soil samples collected byERM-North Central during 1987, an area of VOX-impacted soil existswithin a larger area of minimally impacted soil between Bankert's Pondand Finley Creek. Figures 5 and 6 illustrate the approximate horizontaland vertical distribution of VOXs at Third Site based on headspacemeasurements of soil samples collected during the August 1987 ERM-North Central investigation. The seepage samples, collected during thesame year, consisted of surficial soil and water samples from two areasof observable ground water seepage. These samples also containedVOXs. The seepage sample locations as well as their VOXconcentrations are shown on Figure 7. Examples of the types ofcompounds encountered in the seepage samples and their ranges ofdetected values are:

Compound Seepage/Water Surficial Soil

cis-l,2-Dichloroethene 7.9 to 120 mg/L 4.9 to 36.5 mg/g

1,1,1-Trichloroethane 1.8 to 23 mg/L 1.4 to 1.6 mg/g

1,2-Dichlorobenzene .185 to 4.6 mg/L 8.8 to 38.4 mg/g

Xylenes .1 to 2.48 mg/L 2.0 to 7.4 mg/g

Vinyl chloride .444 to 1.64 mg/L nondetect

The analytical results for Third Site soil samples collected by ERM-North Central and CH2M Hill are presented in Figure 8 and in Table 1.The VOXs detected in the near-surface soils at borings SB-11 and SB-12appear to be related to the use of this area for truck parking in themiddle 1970s. The compounds detected are those typically found indiesel fuel, notably toluene and total xylenes. The VOXs at Third Siteconsist primarily of halogenated VOXs, toluene, and xylenes, and areconcentrated along the southeastern bank of Bankert's Pond. Thissoutheastern bank of the pond was formed when an estimated 6 to 8feet of fill materials were placed in the area between the Pond andFinley Creek. Total VOXs in the soil samples ranged from not detectedto 6,018 mg/kg. Examples of the types of VOX compounds encountered

ERM-ENVIROCLEAN-NORTH CENTRAL. INC. O CREEK REALIGNMENT PROJECT

in the soil samples taken from soil borings and their ranges of detectedvalues are:

Compound Subsurface Soil Samples

Chloromethane Not detected to .003 mg/kgChloroethane Not detected to .018 mg/kgCarbon disulfide Not detected to .004 mg/kg1,1-Dichloroethene Not detected to 2.1 mg/kg1,1-Dichloroethane Not detected to 5.2 mg/kgcis-l,2-Dichloroethene Not detected to 58.5 mg/kgtrans-l,2-Dichloroethene Not detected to 1.6 mg/kg1,2-Dichloroethene (total) Not detected to 14.000 mg/kgMethylene chloride Not detected to .008 mg/kgChloroform Not detected to 2.8 mg/kg2-Butanone Not detected to 1.7 mg/kgTetrachloroethene Not detected to 588 mg/kg1,1,1-Trichloroethane Not detected to 913 mg/kgVinyl chloride Not detected to .070 mg/kgTrichloroethene Not detected to 3310 mg/kgToluene Not detected to 57 mg/kgEthyl benzene Not detected to 164 mg/kgXylenes (total) Not detected to 1020 mg/kg

VOXs were also detected in ground water samples but their source(s) isuncertain. The analytical results for Third Site ground water samplescollected by ERM-North Central and CH2M Hill are presented in Table2.

We know of no data concerning VOX concentrations or SVOCconcentrations, if any, in the pond water.

2.3.2 SVOC Distribution

The following SVOCs were detected in the soil samples collected fromthe Third Site area limits shown in Figure 8: 1,2-dichlorobenzene; di-n-butyl phthalate; and bis(2-ethylhexyl)phthalate. Only the ground watersamples collected from the MW-19 well pair contained SVOCs, and onlytwo SVOCs were detected in these samples (i.e., 1,2-dichlorobenzeneand 1,4-dichlorobenzene). The source(s) of SVOCs detected in theground water is uncertain. In general, the dichlorobenzenes wereassociated with the VOXs and were detected at concentrations withinthe same order of magnitude or less than the VOX concentrations. Theanalytical results for Third Site ground water samples collected by ERM-North Central and CH2M Hill are presented in Table 2.

ERM-ENVIROCLEAN-NORTH CENTRAL. INC. O CREEK REALIGNMENT PROJECT

2.3.3 Inorganics Distribution

No inorganics were detected above background levels in the groundwater samples collected by CH2M Hill. Aluminum, antimony, barium,cadmium, and silver were detected slightly above background in somesamples collected by CH2M Hill. These results are shown on Figure 8.

2.4 POND CONDITIONS

The configuration of the bottom of the pond was determined byERM-North Central in March 1990 (see Figure 9). As shown in Figure 9,the bottom of the pond is deeper than Finley Creek, and a headdifference of approximately 6 feet exist between the water surfaces ofthe pond and Finley Creek at the time of the pond bottom wassurveyed. A sand and gravel unit was identified in monitoring wellMW-19B during CH2M Hill's 1988 study. A limited volume of seepagefrom this unit was observed by ERM-North Central in 1987 along FinleyCreek. The existence of this head difference and the low seepage rateindicate that the sand and gravel unit is not continuous from the pondto the creek.

2.5 STREAMLINED RISK EVALUATION

During the ERM-North Central investigation, VOXs were found insamples of seepage migrating into Finley Creek. Based on the analyticalresults for the water samples collected by the USEPA under normalflow conditions from Finley Creek, Eagle Creek, and Eagle CreekReservoir, the VOXs volatilize as they are transported by the creekwater.

During periods of high flows in Finley Creek there is a risk that rapiderosion and resulting instability of the stream bank adjacent to the sitecould greatly and suddenly increase the amount of soils containingVOXs entering the Creek. An increase in the rate of flow is typicallyobserved during springtime and early summer. In view of theconnection of Finley Creek to the Eagle Creek Reservoir, which is asource of drinking water for the City of Indianapolis, a Time CriticalAction is warranted because:

• There exists the potential for contamination of drinking watersupplies;

• There are VOXs in the soil at or near the surface that maymigrate; and

ERM-ENVIROCLEAN-NORTH CENTRAL, INC. / CREEK REALIGNMENT PROJECT

There are weather conditions (i.e., spring rains and subsequenthigh flows in Finley Creek) that may cause VOXs to be suddenlyreleased through rapid erosion and/or a breach of the berm.

ERM-ENVIROCLEAN-NORTH CENTRAL, INC. 8 CREEK REALIGNMENT PROfECT

3.0 DESCRIPTION OF PROPOSED PROJECT

The objective of the Project is to significantly reduce the risk of asudden discharge of VOXs to Finley Creek. To reduce this risk, the"oxbow" bend in Finley Creek, which is adjacent to Third Site, will berealigned away from the soil area containing VOXs.

The components of the Project (Figure 10) consist of:

• Excavation of a creek cutoff to divert Finley Creek from the"oxbow" bend adjacent to the VOX containing soil at Third Site,and

• Closure of the upper end (upstream) of the "oxbow" with a soildam and then fill the former "oxbow" creek bed adjacent to ThirdSite with excavated material from the creek cutoff.

Diverting the creek water through an excavated cutoff that bisects theFinley Creek meander (Figure 10) will: (1) reduce the potential for eithergradual or sudden migration of VOXs into the creek, (2) reduce the riskthat surface water from Finley Creek will enter the VOX containingsoils, and (3) stabilize the creek bank to prevent erosion or sloughing ofsoils during future remediation.

Diverting Finley Creek will require meeting the substantiverequirements of: (1) the Indiana Department of Natural Resourcespermit for construction in a floodway, and (2) the Department of theArmy, Nationwide Permit, 33 CFR 325. As this work meets theUSEPA's National Contingency Plan definition of on site, actual permitsare not required. A review of aerial photographs of the site takenbetween 1950 and 1986 shows there has been no industrial or disposalactivities to the south of Finley Creek in the area of the creekrealignment.

3.1 SCOPE OF WORK

Figure 10 indicates a preliminary location plan for the proposed channeldiversion. The final location and channel design will be determinedbased on completion of the following items:

• Site survey and analysis of proposed location for the channeldiversion,

• A cross-sectional survey of the existing "oxbow" bend along withsections upstream and downstream of the proposed channeldiversion,

ERM-ENVIROCLEAN-NORTH CENTRAL, INC. 7 CREEK REALIGNMENT PROJECT

• A hydraulic study of the Finley Creek at the "oxbow" bend todetermine 100-year flood elevations and flow designrequirements, and

• A site survey indicating property boundaries.

Authorization from the property owner to conduct the necessarysurveys has been obtained. A copy of the authorization letter has beenincluded as Appendix A. On completion of the design, we will providethe USEPA and Indiana Department of Environmental Managementwith one design report (deliverable) containing the following:

• Existing site survey,• Hydraulic Assessment of the affected section of Finley Creek,• Plans and cross sections of proposed construction,• Erosion control plan for use during and after construction,• Construction specification, and• Schedule.

Upon approval of design documents, the construction of the proposedditch diversion will be conducted in accordance with the designdocuments and the applicable regulations.
