1.1 Scope of Work

At the request of the United States EnvironmentalProtection Agency, Region V (U.S. EPA), JacobsEngineering Group, Inc. (Jacobs) was issued a WorkAssignment to provide compliance monitoring of remedialinvestigation (RI) activities at the City DisposalCorporation Landfill (CDCL) of Dane, Wisconsin. Thisactivity was assigned under the Technical EnforcementSupport (TES) Contract Number 68-01-7351. Jacobssubcontracted Metcalf & Eddy, Inc. (M&E) to providethis compliance monitoring. The scope of this workconsisted of Work Plan Preparation; Evaluation orReview of All Technical Documents and Reports;Oversight of Field Work; Participation in CommunityRelations and a Pre-Feasibility Study Meeting. Thisreport was prepared in order to document field workperformed to date.

M&E provided oversight of RI activities conducted atCDCL from 14 November 1988 through 30 November 1988.M&E performed this oversight to assure compliance withthe procedures specified in the RI/FS Work Plan. Theactivities performed during this phase included:

Installation of Surface Water Monitoring GagesExisting Monitoring Well InventoryGeophysical SurveyCover Survey and Soil Sampling

These activities were performed by P.E. La Moreaux andAssociates, Inc. (PELA) of Tuscaloosa, Alabama inaccordance with the RI/FS Work Plan for CDCL preparedon behalf of Waste Management of Wisconsin, Inc.

This report provides a summary of this phase of fieldactivities at CDCL. Photographs were taken in order todocument field activities and are attached in AppendixA.

1.2 Site Background

The CDCL is located on approximately 38 acres in thesouthern half of Section 30, Township 6 North, Range 10East in Dane County, Wisconsin (Figure 1). The sitewas first licensed and utilized in 1966 and closed inJanuary 1977. The site was operated by City DisposalCorporation and later by Acme Services, Inc. incompliance with NR 151 and licensed throughout theoperational period in accordance with prevailingregulations. Upon closure of the site both CityDisposal and Acme were acquired by Waste Management ofWisconsin, Incorporated (WMWI).

According to engineering plans completed by SoilTesting Services of Wisconsin, Inc., the landfill iscomprised of 12 cells. Cells 1,2,3,4,6 and 12 werefilled or partially filled. The remaining cells werenever utilized for landfilling purposes. Cells 1 and12 were used from 1966 to 1974. Cells 2,3,4 and 6 werefilled or partially filled from 1974 until closure in1977. Cell 12 accepted industrial wastes from 1966through March 1975. These wastes included xylene,naphtha, cyclohexanone, tetrahydrofuran, and oil-watermixtures (1).

1.3 Project Approach

Participation in Community Relations and Pre-Feasibility Meeting

The TES Contractor participated in a Kick-off meetingon 29 September 1988. This meeting was attended bypersonnel from the U.S. EPA, Wisconsin DNR, PELA, WMWIas well as concerned citizens from the community. TheTES Contractor will participate in any future communityrelation activities as requested by the U.S. EPA. APre-Feasibility Study Meeting will be held with EPA,the TES Contractor, and appropriate Staterepresentatives to discuss the direction of the FS,specific areas to be addressed, probable technologies,and possible alternatives.

SECTION 2.0

SURFACE WATER MONITORING

2.1 Purpose

In order to assess the hydraulic relationship betweenthe surface water and ground water systems, monitoringof surface water elevations will be conductedthroughout the RI.

2.2 Monitoring Locations

Permanent monitoring gages were installed in Grass Lakeand Badfish Creek on the eastern portion of the site.On 15 November 1988, four staff gages were installed inBadfish Creek and one staff gage was installed in GrassLake (see Figure 2). Of the gages monitoring BadfishCreek, one was placed immediately south of the bridgeand designated as SW-4; a second was placed upstream,approximately 200 ft. north of the bridge anddesignated as SW-3; a third gage located north of SW-3was already present from another investigation, and wasdesignated as SW-2; a fourth gage was installedadjacent to Grass Lake and designated as SW-1. A fifthstaff gage, SW-5, was installed in Grass Lake adjacentto Badfish Creek.

Readings were taken from the gages periodically andrecorded with the date and time. These gages will besurveyed by a licensed surveyor at a future date.

EXISTING MONITORING WELL INVENTORY

3.1 Purpose

An inventory of existing monitoring wells was performedin order to assess the condition of each well. Theinformation collected from the field will be comparedwith the available drilling and installationdocumentation. These data will serve as a basis fordetermining locations for sampling, well replacementand possible decommissioning of wells.

3.2 Methods

The existing wells were located and the condition ofthe protective casing, surface seal, lock and casingwere inspected and noted. Total well depth and waterlevel elevation were measured for each existingmonitoring well. This inventory was conducted on 20November 1988.

Some wells however, could not be fully inspected ormeasured as PELA was not equipped with a key. Themonitoring wells which could not be accessed were B-12R, B-14, and B-17. Therefore, only limitedinformation on their condition is available at thistime.

SECTION 4.0

GEOPHYSICAL SURVEY

4.1 Purpose

An electromagnetic survey was performed at CDCL duringthis phase of RI field activities. This survey wasperformed in order to obtain information on subsurfaceand near surface conditions.

4.2 Methods

A grid system was established across the site fororientation and spacing of profiles. This grid wassurveyed by Landmark Surveyors of Madison, Wisconsin.It was oriented with the X-axis trending approximatelynorth-south and the Y-axis trending approximately east-west. The origin of the grid was established in thesouth-west corner of the site. Each node on the gridwas characterized by 100-foot spacings. The gridextended from ON,OE to 900N,2700E.

A Geonics Model EM34-3XL electromagnetometer (SerialNo. 8506019) was used. Electromagnetivity was measuredin the vertical and horizontal dipole mode (Serial Nos.Of Poles: RX 8506019, TX 8506019). The poles to the EMwere used at 40 meter spacings at each grid node. Abase line was established for quality assurance at800N,500E to 800N,900E. This line was chosen as thebase line due to its distance from the landfilled area.The base line was visited perodically to assureconsistency of readings. The geophysical survey wasconducted over the grid and extended further out beyondthe grid. The survey was extended further than thegrid in order to obtain background data of naturalsubsurface conditions for the area.

SECTION 5.0

COVER SURVEY AND SOIL SAMPLING

5.1 Purpose

A soil cover survey was performed in order to assessthe composition, integrity, and thickness of theexisting soil cover. Information obtained from thesoil cover survey will also be used in developing awater budget for the site.

5.2 Methods

This survey was conducted at the nodes of the 100-footgrid system established by Landmark Surveyors. PELAused a hand auger to bore into the soil cover. Theborings were examined and documented in a field logbookby PELA. Each boring was extended until either one ofthe following occurred: garbage was encountered,extent of auger was reached (4 ft. length), or theauger was refused (due to solid subsurface materials).

Headspace of the borings was measured with an HNU or aTIP photoionization detector. Soil samples werecollected for analysis of physical parameters in orderto evaluate the permeability of the soil covermaterial. The samples will be submitted for analysisof grain size distribution, compaction, and moisturecontent.

5.4 Soil Sampling

Soil samples were collected for analysis of physicalparameters in order to evaluate the permeability of thesoil cover material. These parameters to be measuredare grain size distribution, compaction, and moisturecontent. The node locations for soil sample collectionwere selected using a random sorting function on apersonal computer. Forty sampling points were selectedfor collection of samples and are listed in Table 1.Two samples were not collected since they were locatedin a cow/bull enclosure. Thus, thirty-eight sampleswere collected for analysis of grain size distributionand moisture content. Additional sample volume wascollected from five sampling locations for analysis todevelop compaction test curves.

Each sample collected was placed in a one-gallon sizeZiploc baggie. The baggie was labeled with permanentmarker with the sampling location, date and time ofcollection, depth of collection, and sampler'sinitials. Each sample was a representative compositeof the boring from the ground surface to the end of theboring. The sample bags were sealed and stored in thelocked trailer. The samples will be transported backto Alabama and hand delivered to the lab oratory foranalysis. For transportation, each sample will beaccompanied by a chain-of-custody form developed byPELA. The chain of custody form includes the samplelocations, the dates and times of collection, thesignature of the relinquisher plus date and time whichthe samples were relinquished. The original chain-of-custody record will accompany the samples to thelaboratory, and a copy will be retained by the fieldproject coordinator.

The hand auger was decontaminated in between each nodeon the grid. Decontamination procedures consisted ofwashing the auger with a bristle brush in a soapsolution of brand "Tide" and distilled water. Theauger was then allowed to air dry. The water used fordecontamination was poured into a collection tankinstalled underground beneath the decontamination pad.The decontamination water collected in this tank willbe emptied when full or at the completion of theproject. This water will be disposed of at a treatmentplant.
