RE: Proposal for Additional Subsurface Investigations
Wright Avenue Park, Elgin, Illinois
ESE Proposal No. 559-6999-0171
Dear Mr. Bone:
Environmental Science & Engineering, Inc. (ESE) is pleased to provide the following proposal
for Additional Subsurface Investigations at the Wright Avenue Park in Elgin, Illinois. This
proposal has been prepared in response to your verbal request dated August 7, 1996 for
recommended additional activities needed to resolve the issue concerning the landfill at Wright
Avenue Park.
SITE BACKGROUND
On July 12, 1996, ESE installed six soil borings along the east side of Wright Avenue Park to
assess current subsurface conditions for potential environmental impacts that may have resulted
from past dumping in the park.
Records supplied by the Parks and Recreation Department consisted of city council minutes and
historical photographs indicating that this area was used as a source for dumping in the 1950's.
It is also reported that the City of Elgin deposited refuse lime sludge deposits from the municipal
water treatment plant along Wright Avenue during that time period. The area was then covered
with top soil and converted into a park in the late 1950's.
The City of Elgin Parks and Recreation Department is currently proposing to install new
playground equipment, including a roofed picnic structure along the northeast corner of the park
where these lime sludges were reportedly deposited.
Results of the subsurface investigation performed by ESE on July 12, 1996 confirmed the
presence of the lime sludges along Wright Avenue. The lime sludge was first noted at a depth of
2.5 feet to 4.0 feet below land surface (bls) and averaged approximately 15 feet thick. The exact
extent of the lime sludges within the subsurface was not determined during that phase of the
investigation but is estimated to be approximately 100 feet by 300 feet in size.
The native soils surrounding the lime sludge deposits consist of coarse grained sands associated
with the Fox Valley Flood Plain. Groundwater was encountered at approximately 26 feet bls.

ESE collected soil samples from each of the six soil borings for laboratory analysis. Two
samples were collected from each boring. One sample was collected from the lime sludge
deposits and a second sample was collected from the underlying native sands at the water table
interface. The six samples from the lime sludges were composited into one sample for analysis.
Concurrently, the six samples from the sand deposits were also composited into one sample.
Both sample sets were analyzed for Total Organic Halides (Extractable) EOX, Total RCRA
Metals (8), Total Petroleum Hydrocarbons (TPH), and pH.
One analytical parameter was identified in the analytical results from the lime material that may
be of concern and warranted further investigation. This parameter was Barium which was
detected at a concentration of 7,660 parts per million (ppm). Background concentrations of
barium in soils typically ranges from none detected to 1,720 ppm. The barium concentration in
the soils underlying the lime deposits was detected at 15 ppm which is within the range for
background conditions.
PURPOSE
The purpose of this proposal is to identify additional steps needed to determine if any health risks
and/or environmental impacts associated with the barium are a threat to human health and the
environment. Based upon the data collected to date, ESE has identified three issues of concern
that should be addressed:
Task 1. Are there any health risks from barium exposure to the community associated with
using the park on a recreational basis,
Task 2a. Is the lime sludge deposits within the subsurface considered a hazardous material
as defined by the U.S. Environmental Protection Agency (EPA),
Task 2b. Has barium impacted the underlying groundwater,
In addition to the tasks identified above, ESE also recommends that the following be considered
as optional tasks:
Task 3. If tasks 1, 2a and 2b identify areas of concern associated with the barium then the
horizontal and vertical extent of the lime sludge deposits should be delineated to
determine the total volume of lime sludge material at the site.
Task 4. Could the lime sludge deposits, identified 2.5 feet to 4.0 feet bls, adversely impact
the structural integrity and long term performance of the planned picnic structure
and other future development.

SCOPE OF WORK
A scope of work has been developed to address the issues described above. The tasks described
above have been prioritized according to immediate issues regarding their impacts to the
community and environment. Tasks 1, 2a and 2b have been identified as issues of immediate
concern and are the basis for this proposal. These tasks include collecting surface soil samples
for statistical evaluation of the health risks associated with exposure to barium, collecting
subsurface samples of the lime sludge deposited and underlying sand deposits for hazardous waste
characterization of barium concentrations, and the installation of three monitoring wells to assess
current groundwater conditions and determine if barium has leached into the underlying
groundwater.
Tasks 3 and 4 do not present issues of immediate concern and can be addressed in the future.
Task 3 involves the delineation of the horizontal and vertical extent of the lime deposits.
Delineating the extent of the lime deposits should be implemented to determine total volume of
the material if it is determined that the lime deposits are a threat to health and environment. If
the results of Tasks 1, 2a, and 2b do not identify health issues or environmental impacts then
determining the extent and volume of the sludge material may not be warranted.
Task 4 consists of a geotechnical evaluation of the lime sludge material. Since this material was
identified at 2.5 feet to 4.0 feet below the surface, the structural integrity of any future structures
may be compromised. Costs for both Tasks 3 and 4 have been included as optional services and
can be implemented at the request of the City of Elgin.
A detailed description of the scope of work described above is presented below included in the
following sections:
Task 1 Surface Soil Sampling
ESE will collect shallow surface samples from within the area of the suspected extent of the lime
sludge deposits. The purpose of collecting the shallow soil samples is to assess soil conditions
near the surface for concentrations of barium that may pose a potential risk to the community
during normal contact with the ground surface of the park. Soil data collected will be compared
to the Tier 1 risk based cleanup objectives for residential properties utilizing Illinois' Tiered
Approach to Cleanup Qbjectives (TACO).
ESE will collect 10 soil samples placed in a grid pattern over the area that overlies the lime
deposits (assumed to be 100' X 300'). The grid pattern will be more closely spaced in the area
of the playground at the northeast corner of the park and further spaced along the topographic
slope along Wright Avenue. Five samples will be collected from the area of the playground
(approximately 100' X 100') and five samples will be collected from the remaining subject area
(approximately 100' X 200'). This grid pattern will allow for more emphasis on soil sampling
within the playground which is used more extensively by the community.

Before implementing the shallow soil sampling activities, ESE will install survey control points
within the subject area to provide accurate location of each sampling point. Survey control points
will be tied into known features within the park, such as street curbs, utility manways, streetlight,
or baseball backstop.
Prior to commencing work at the site, a Health and Safety Plan will be prepared for ESE
personnel to address personal protection, decontamination, and other health and safety related
issues. The plan will consider conditions relevant to the site and will be reviewed by our Health
and Safety Officer. ESE employees working at the site will have completed the OSHA 40 hour
hazardous materials operations and safety training required by 29 CFR 1910.120.
The soil samples will be collected using Hand Auger Techniques. ESE personnel will hand auger
to a depth of approximately one foot below the surface. Soil samples will be placed into
laboratory grade glass jars pending laboratory analysis. ESE will decontaminate soil sampling
equipment between the collection of each sample and boring to assist in preventing cross
contamination of borings. The decontamination procedure used for sampling equipment will
consist of Alconox wash, tap water rinse, followed by a distilled water rinse.
The soil samples will be placed in a cooler with ice pending delivery an approved analytical
laboratory. Laboratory analysis will be performed for Total Barium in accordance with the
methods contained in U.S. EPA's Test Methods for Evaluating Solid Wastes, 3rd Edition (SW-
846). Upon collection, each soil sample jar will be labeled with the site name, sample location,
date, and time. The sample cooler will then be hand delivered or sent via overnight courier
(UPS or Federal Express) to the analytical laboratory. Sample preservation and chain-of-custody
protocol will be maintained.
For the purpose of this proposal the costs for the 10 shallow soil samples will be based on a
standard turnaround of two weeks. An expedited 3-day turnaround can be implemented at the
request of the City of Elgin. A 50% surcharge will apply to the expedited turnaround.
Tasks 2a and 2b Monitoring Well Installation and Hazardous Material Determination
Task 2a will involve the installation three temporary groundwater monitoring wells to assess
current groundwater conditions underlying the lime sludge deposits. The purpose of the
groundwater investigation is to determine if barium has leached from the lime sludge into the
groundwater.
The installation of the three monitoring wells will be performed using a truck-mounted rotary
drill rig equipped with six-inch I.D. hollow stem augers. The borings will be sampled at 2.5 foot
intervals using a two-inch diameter split-barrel sampler. The borings will be continued to a depth
of approximately 32 feet bls in an attempt to intersect the water table which is anticipated to be at
26 feet bls.
The monitoring wells will be installed in accordance with applicable federal, state and local
Mr. Stephen G. Bone
Wright Avenue Park
August 13, 1996
Page 5
regulations. The wells will be constructed of two-inch diameter PVC well material. The wells
will be equipped with 10-foot-long 0.010-inch slot well screen. The screened intervals for the
wells will be constructed with the slot openings extending approximately three feet above the
water table. The wells will be completed at land surface with a four-inch-square steel protective
cover which will be cemented in place to a depth of one to two feet bls.
Following installation, the wells will be developed to provide a relatively low turbidity and
representative groundwater sample. After allowing the grout seals in the wells to set overnight,
each well will be developed by purging a minimum of five well volumes from the wells. The
wells will then be allowed to set for a short period (2 to 3 days) prior to sampling to allow a
minimum amount of time for groundwater to reach equilibrium within the wells. Additionally,
the ground surface and top of the riser pipe of each well will be surveyed to the site specific
datum to establish elevation control for data evaluation.
ESE will obtain groundwater elevation levels from each monitoring well to ascertain groundwater
flow direction. ESE will collect one groundwater sample from each monitoring well to assess
groundwater conditions. Prior to the collection of the groundwater samples, the wells will be
purged to remove a minimum of three well volumes of water to ensure that the samples collected
are representative of the actual conditions. The groundwater samples will be collected
immediately after the wells have recharged with a sufficient volume of water to allow for
collection of samples.
Groundwater samples will be placed in a cooler with ice pending delivery to an approved
analytical laboratory. Laboratory analysis will be performed for TCLP Barium and pH in
accordance with the methods contained in U.S. EPA's Test Methods for Evaluating Solid Wastes,
3rd Edition (SW-846). Upon collection, each soil sample jar will be labeled with the site name,
sample location, date, and time. The sample cooler will then be hand delivered or sent via
overnight courier (UPS or Federal Express) to the analytical laboratory. Sample preservation and
chain-of-custody protocol will be maintained.
In addition to the collection of the groundwater samples, ESE will collect soil samples (Task 2b)
of the lime sludge and underlying sand deposits for hazardous material determination and
exposure for construction workers working in the lime deposits during construction of the new
playground equipment. A total of 9 soil samples will be collected for analysis. Six (6) samples
will collected from the soils for TCLP Barium and pH analysis as follows: Three (3) soil samples
from the lime sludge and three (3) soil samples from the underlying sand deposits at the
groundwater interface. Three (3) samples from lime sludge deposits will also be analyzed for
Total Barium. The analysis will be performed in accordance with the methods contained in U.S.
EPA's Test Methods for Evaluating Solid Wastes, 3rd Edition (SW-846).
For the purpose of this proposal the costs for the three groundwater samples and nine soil
samples will be based on a standard turnaround of two weeks. An expedited 3-day turnaround
can be implemented at the request of the City of Elgin. A 50% surcharge will apply to the
expedited turnaround.

Task 3 Geophysical Delineation of Extent Lime Sludge Deposits (Optional)
If required ESE will implement the geophysical phase of the project to determine the extent of
the lime sludge deposits. Implementation of the geophysical phase will be dependent on the
chemical laboratory results. If-the laboratory results do not indicated environmental impacts such
as surface exposure of barium to the community or classification as a hazardous material, then it
is assumed that corrective action may not need to be implemented and monies spent to delineate
the extent of the lime sludge may not be warranted at this time.
The geophysical survey will consist of electric resistivity (ER) conductivity survey to locate a
suspected lime sludge deposits. The ER survey is capable of delineating both the horizontal and
vertical extent of the lime deposits. This method will be very effective in determining the
volume of sludge deposits at the subject site. There are other geophysical methods available for
lower costs, such as an electromagnetic (EM) conductivity survey. However, these methods will
only determine the horizontal extent of the lime sludge. Therefore, the total volume of the
material will not be able to be determined using this technique.
Determining the extent and volume of the sludge material by geophysical methods is a very
effective non-evasive technique. Attempting to delineate the horizontal and vertical extent of the
lime sludge by evasive techniques such soil borings or soil probes will generate large amounts of
potentially impacted soils that will need to be properly disposed of.
The ER survey will be conducted using a Sting R1 earth resistivity meter, which measures
the apparent conductivity of the subsurface employing an artificial source which is introduced
through point electrodes. The Sting measures electrical potentials at other electrodes.
The Swift automatic electrode system will be connected to the Sting to optimize survey
efficiency by gathering maximum information with a minimum of electrodes. The Swift also
uses redundancies in the data set to reduce the effects of lateral heterogeneities in the earth
and to calculate uncertainties in the data. The survey will be conducted automatically using
the Sting/Swift dipole-dipole system.
The survey area will include an area of approximately 1 acre for the ER. Electrode spacing
will be at 10-foot centers along 25 foot lines. The work will be performed by a Project
Geophysicist, and the expected timeframe for the field investigation will be approximately
one day.
The geophysical survey will only be implemented after receipt and interpretation to the
chemical analytical results and authorization by the City of Elgin.

Task 4 Geotechnical Analysis of Lime Sludge Deposits (Optional)
Four borings will be advanced at locations provided by the Parks and Recreation Department
to provide an accurate description of the subsurface conditions for the construction of
playground and picnic structure. It is recommended that boring locations be staggered and
not placed in a single line across the subject area.
Geotecnical borings can be completed concurrently with the monitoring wells installation.
Borings will be advanced to a depth approximately five feet below the base of the lime
deposits using hollow stem augers. Based on the available data, it is estimated that each
boring will be advanced to approximately 30 to 32 feet below ground surface. Standard
penetration tests (SPTs) will be taken every five feet starting at the five foot interval using a
standard 2-inch diameter split-barrel sampler equipped with four brass sample liners.
Following the SPIT, the core liners will be removed from the barrel and inspected to
document and log the lime deposits or soils encountered. At least two of the core liners
from each sample interval will be retained for laboratory geotechnical analyses. Sample
liners will be capped with plastic caps, sealed with duct tape and labeled with the boring
location and sample depth.
The geotechnical testing program will include the following:
• 15 Unit Weight/ Moisture Contents (ASTM D2216)
• 4 Atterberg Limits (ASTM D 421, D 422)
• 4 Specific Gravity (ASTM D 421, D 422)
• 2 Modified One Dimensional Consolidation Tests (ASTM D 2435)
Selected soil samples for geotechnical analyses will be delivered to Tri-Tech Engineering in
St. Charles, Illinois. A chain of custody will be used to document the number of samples,
sample identifications and geotechnical testing program for each sample. Geotechnical -
testing results will be forwarded directly to Chicago office.
Following receipt of the geotechnical testing data, the following geotechnical evaluations will
be conducted:
• Soils Classification: Soils encountered during drilling will be classified in
accordance with the Unified Soils Classification System (USCS).
0 Preliminary Settlement Analyses: Using the results of the one dimensional
consolidation testing, settlement analyses will be conducted to provide preliminary
Mr. Stephen G. Bone

Page 8
estimates of total and differential settlement that the landfill could experience with
time.
• Preliminary Stability Analyses: Preliminary slope stability analyses will be conducted
to evaluate any potential slope instability that could occur.
• Bearing Capacity and Shear Strength: Comparison of actual versus estimated
available shear strength will be conducted to assess the bearing capacity of the lime
deposits.
The objective of these activities will be to identify geotechnical characteristics of the lime
deposits that could adversely impact the integrity and long term performance of any future
development. The results of the drilling program, geotechnical testing and geotechnical
evaluations will be documented in a letter report that will include recommendations for
additional testing and/or actions that could mitigate any unacceptable settlement or reduce the
potential for slope instability.
PROTECT SCHEDULE
ESE will initiate the proposed activities within seven (7) working days of being authorized to
proceed. ESE anticipates that the installation and development of wells will require one
week to complete. Analytical testing is anticipated to be completed in two weeks and a final
report to be delivered within two weeks of receipt of the analytical results.
The geophysical survey (Task 3), if warranted and authorized, can be initiated within two

BASIS FOR PROPOSAL
The estimated costs identified above are based on assumptions made from the limited
knowledge regarding site conditions currently available. Although unlikely for this scope of
work, these costs are subject to change if additional information regarding drilling, sampling
or analytical conditions are discovered.
Assumptions used to prepare the cost proposal include the following:
• ESE has not included costs for characterization and disposal of the investigation
derived wastes generated during this project.
• ESE has assumed that the proposed drilling locations will be accessible using a truck-
mounted drill rig. If site conditions warrant use of alternate drilling equipment (i.e.,
ATV rig) additional charges may apply.
• No Client or Agency meetings have been budgeted for this proposal. Costs for ESE
attendance in meetings will be on a time and materials basis per the Professional Fee
Schedule.
• The City of Elgin will provide access to both properties and identify a project contact.
• Efforts will be completed in accordance with applicable state, federal, and local
requirements.
• ESE will contact the local underground utility notification service prior to initiation of
drilling activities at the site and will obtain location clearance from the plant contact.
• The City of Elgin will be notified of unforeseen changes in the project budget.
• Equipment and personnel standby charges will be applied during unanticipated project
delays not under the control of ESE or it's subcontractors.
• ESE has assumed that difficult drilling conditions will not be encountered. In the
event any unidentified underground structures or difficult drilling conditions are
encountered, additional costs may be incurred.
• A Modified Level D Health and Safety Program will be adhered to by all ESE and
subcontractor personnel. If Level C or other conditions are determined necessary by
ESE personnel, additional charges will apply to meet the level of protection
requirements.

Agenda Item Nos
September 19, 1996
TO: Mayor and Members of the City Council
FROM: Richard B. Helwig, City Manager
SUBJECT: Wright Park Investigative Study
- Lime Sludge
PURPOSE
The purpose of this memorandum is to provide the Mayor and
members of the City Council with background information
concerning Wright Park and the proposed environmental investi-
gation of lime sludge deposits at the site.
BACKGROUND
In response to neighborhood citizen requests for improvements
to Wright Park, staff conducted community input meetings in
May and June to discuss the Wright Avenue Park project. At
the May meeting, a citizen mentioned his recollection of the
City of Elgin "dumping" lime sludge from the water treatment
plant at the park site it the early 1950 's . Staff researched
the allegation and found that the City had, in fact, utilized
the area as a lime sludge disposal site prior to establishing
Wright Park.
In early July, Environmental Services And Engineering, Inc.
(ESE) was retained to perform a preliminary site investiga-
tion to assess the subsurface soil conditions for potential
environmental impacts within the site. The investigation
concluded that lime deposits averaging 15 feet in depth were
present along the northeast corner of the site, with barium
contamination at higher than normal background levels .
Discussions with the IEPA confirmed that additional testing
would be prudent to determine the following:
1 . The extent of the contamination at the site,
including a "footprint" of lime deposits.
2 . Health risks from barium exposure to the general
public, associated with use of the site for
recreational purposes .

3. If lime sludge deposits within the subsurface soils
were of sufficient concentrations to be considered
hazardous material per IEPA
4 . If the barium contamination had impacted the
underlying groundwater.

,., STATUS OF WRIGHT PARK STUDY TO DATE
City hired a consultant to conduct a site investigation of the Wright Park
area.
Five (5) borings were drilled along the east perimeter of the park and one (1) in the
center of the south end of the park.
These areas were chosen because the City's records indicated that these were the
locations of the lime sludge disposal in the 1950's.
Lime deposits were encountered in the borings along Wright Avenue to a depth of
apprx. 18 feet. The lime deposits are covered with a cap of dirt, two and one half
to four feet deep. There is approx. eight feet of sand below the lime deposits.
Samples were collected from the borings and sent to a lab for analysis. Analysis
showed elevated concentrations of Barium in the lime deposits.
Details about Barium
Barium is a naturally occurring heavy metal which is the 16th most common
element.
It makes up approximately 1/2,000th of the earth's crust.
It cannot be found in its pure form in nature. It usually binds with another material
It only has limited number of uses, including medicine, rubber and paint
manufacturing.
It has a very low toxicity unless exposure is at high concentrations and duration of
exposure is extended/repeated.
City's samples were found to be 7,660 ppm -Found in the lime sludge deposits.
IEPA guidelines= 5,500 ppm for ingestion 350,000 ppm for inhalation
- measurements taken from the first 3 meters of soil (surface exposure)
- In a RESIDENTIAL setting where there is continuous exposure.
- ACUTE EXPOSURE is 100 times the levels found in our samples.
-Worker exposure is 14,000 ppm(higher due to limited time exposure)
RISK AT THIS SITE UNDER THESE CONDITIONS IS BASICALLY NONE
-Barium in this form is usually not volatile.
- It is not usually very mobile.
-Posses no health threat to the general public.
-RISK is basically NONE at the-reported levels under the present
conditions with the 3-4 foot cap of soil.
- Possible Problems -Migration of the barium into the underlying ground
water. IEPA has Standards for this type of contamination.
GUIDELINES vs STANDARDS - SET BY IEPA
Guidelines are suggestions for levels/concentrations of contaminants. The
clean-up is voluntary, not mandatory.
Standards are strict maximum levels. If you exceed the standards, you
could be in violation of the law and you may clean up the contamination.
IEPA also consideres"site specific" clean-up standards for special
circumstances/cases.
INTENDED ACTIONS BY THE CITY AT THIS POINT
-Hire a consultant to do additional borings and studies to determine the following:
1. Analysis of the barium through the sample analysis.
2. Determine extent of contamination - how large of an area does it cover
3. Determine the"leachability" of the barium through testing of soil samples.
4. Determine if the barium has impacted the ground water.
5. Determine the structural integrity of the soil/sludge to support anticipated play
ground equipment.
-Two environmental firms are currently formulating bids for the proposed work. We
should have the bids back in a week or so. The contract could be awarded within two
weeks.
- Contractor would put together a SITE REI IEDIATION PROGRAM for submittal and
review by IEPA. This process, including IEPA rview could take as long as three months.
- IEPA could say that no further action is rerquired and that nothing needs to be done at
the site.
- IF further action is deemed necessary by IEPA, then they would determine what
action(s)were necessary , and set guidelines for desired levels of contamination. Clean-up
would be voluntary by the City.
- If City conducts clean-up, the environmental contractor would follow the IEPA
approved Site Remediation Program.
-IEPA would review the Program results and make a determination of
No Further Action Required or Additonal Action to be Taken
- Disturbance of the lime materials by any means would require monitoring to eliminate
possible surface and air contamination.
