Introduction
This report summarizes the results of groundwater, surface water and water level monitoring
work completed by Viacom Inc. during the second quarter of 2002 at the Lemon Lane Landfill
site.
Monthly groundwater and surface water monitoring was performed at a total of three locations
(springs and streams) in accordance with interim monitoring requirements outlined in the May
2000 Lemon Lane Landfill Statement of Work (SOW) for this site. Continuous monitoring of
water levels was also performed at seven locations.
2.0 GROUNDWATER AND SURFACE WATER MONITORING
The monitoring work described in this report was performed on May 21, June 10 and July 17,
2002. This three month time period constitutes the second reporting quarter for Lemon Lane
Landfill for 2002.
Scope of Work
The scope of groundwater sampling for this monitoring period comprised monthly sampling
stipulated in the SOW, as summarized in Table 1.
Groundwater and surface water sampling was performed at the following locations:
Quarry Springs
- Illinois Central Spring
-
Slaughterhouse Spring
The approximate locations of these stations are shown on Figure 1, Monitoring and Sampling
Locations.
Sample Collection and Handling
Samples at the spring and stream locations were collected by carefully filling a new disposable
beaker. The water was transferred from the beaker into pre-cleaned amber glass 1-liter bottles
supplied by the analytical laboratory. Routine sampling parameters including temperature and
conductivity were measured and recorded. Spring or stream flow was also estimated and
recorded.
Samples were analyzed by Heritage Lab of Indianapolis, Indiana. The samples were analyzed to
a detection limit of 0.1 parts per billion (ppb) for all PCB parameters (except Aroclor 1221;
detection limit 0.5 ppb) by EPA SW-846 method 8082. Samples were also analyzed for total
suspended solids (TSS) by EPA method 160.2.
Quality Assurance
For quality assurance purposes a duplicate sample and a field blank were collected during each
sampling event. All environmental and blank samples were labeled and logged onto a chain-of-
custody form. The samples were stored and transported on ice in insulated coolers. Custody of
the water samples was maintained by Viacom until shipment to the analytical laboratory.
Analytical Results for Surface Water Samples
Field parameter measurements, PCB analytical results, and QA/QC results for water samples
collected during this reporting period, as well as historical (post-remediation) sampling are
reported in Table 2 - Quarry Springs, Table 3 - Illinois Central Spring, and Table 4 -
Slaughterhouse Spring (attached). Copies of the chain-of-custody forms are provided in
Appendix A. Copies of the certificates of analysis are provided in Appendix B. A validation
summary for these samples appears in Appendix C. Copies of the field sampling data sheets are
on file at PSARA's Bloomington Branch Office.
3.0 CONTINUOUS FLOW AND WATER LEVEL MONITORING
The purpose of flow and water level monitoring is to evaluate site-specific data characterizing
site hydrologic response under storm and non-storm conditions, and to evaluate correlations
between PCB concentrations, spring flow and Groundwater elevations.
Scope of Work
The scope of Groundwater level and flow monitoring during this reporting period involved the
use of dedicated instrumentation to record water level and other parameters as summarized in
Table 5.
Water lever transducers, water level data logging equipment, and piezometer crest gauges were
operated during all or part of the period from May 2002 through July 2002 at the following
locations:
| Monitoring Location

Equipment |
| Illinois Central Spring |
ICSTF instruments operated by IDEM contractor |

| PZ-BD | In-Situ mini-Troll transducer/datalogger (5/1-7/31) |
| PZ-AS | Crest gauge |
The approximate locations of the stations listed in Table 5 are shown on Figure 1, Monitoring
and Sampling Locations.
Flow and Water Level Plots
The following plots for the monitored stations for this reporting period are attached:
-
water level elevation at MW LF6~, MW LF6-8, and Piezometer BD
-
water elevation and temperature at MOO-6, MW-21, and NN-300
-
water elevation and conductivity at MOO-6 and MW-21
Quality Assurance
As a quality assurance check, rainfall records for this time period were obtained from the Purdue
University State Climatologist's web site (shadow.agru.purdue.edu/sc.index.h~rnI) for the rain gauge
station at the Monroe County Airport. This record was obtained for comparison to the site rain
gauge data, which is located outside the PSARA office.. Raw rainfall data from the web site
appears in Appendix D. Rain events of approximately 0.25 in. or more are indicated on the
attached data plots.
As a further data quality check, manual water level measurements were made after significant
storm events. The purpose of the manual checks was to verify instrument readings. Manual field
check data collected during this reporting quarter are shown on the data plots.
A complete instrument maintenance log for all of the Lemon Lane Landfill installations is
attached as Appendix E. This log details the installation, re-indexing, and maintenance histories
of each transducer and data logger present at Lemon Lane Landfill during the 2nd Quarter.
Discussion
Data for this period are complete except as follows:
-
the mini-Troll at LF6-8 was removed on May 8; no data are available after this date
-
the Troll 4000 at NN-300 was installed on July 22; no data are available prior to this date
-
the Troll 4000 at MW-6 was replaced with a Troll 8000 on July 19; no conductivity data
are available for this station prior to this date
-
the Troll 4000 at MOO-6 was replaced with a Troll 8000 on July 19; no conductivity data
are available for this station prior to this date
the instruments at MW-6 and MW-21 were occasionally removed from their stations for
short periods of time as other investigation activities (e.g. dye trace tests and packer
pump tests) took place there. These activities are briefly noted on the attached plots
The Troll 8000 instrument installed in MWS-2 1 collected some unusual conductivity data during
the month of May. The conductivity meters installed on these transducers typically show a
reduction in conductivity during rain events. This pattern was not always present on the MOO-2 1
instrument during the frequent rain events of lLIay. However, during June and July this
instrument collected more typical data sets. The instrument was removed from MW-21 in early
August, recalibrated for conductivity, and installed in MW4i, where it has continued to collect
typical conductivity data sets. As such, no explanations are available for the unusual
conductivity data in May, and it should be considered suspect. This instrument will be
monitored closely during future downloads to determine a cause for the unusual May
conductivity data.
No abnormal maintenance activities were conducted during this reporting period.
Crest Gauges
A crest gauge was installed at Piezometer AS on June 12. The purpose of this gauge is to
determine the maximum water level present in this piezometer between inspections. The gauge
is checked on a bi-weekly basis. At the time of installation, the piezometer was dry. At the end
of the first two-week testing period, the gauge recorded a crest of 0.12'. This data is suspect
since the piezometer and the gauge's float were still dry at the time of inspection. The design of
this crest gauge makes it possible to create false readings as it is being lowered into or removed
from a well. Additionally, this design does not work in Piezometers AD and BS since their
casings have shifted out of plumb. Newly designed crest gauges were installed in Piezometers
AD and BS in early September. Their effectiveness will be discussed in the report for the third
quarter of 2002.
