Introduction
Concerns have been raised about hazardous waste treatment, storage, and
disposal (TSD) facilities complying with the ground-water monitoring require-
ments promulgated under the Resource Conservation and Recovery Act (RCRA).
The two primary concerns are the ability of existing and/or proposed ground-
water monitoring systems to immediately detect releases of contaminants to
the ground water, and to determine if the ground water contains hazardous
waste constituents. The Administrator of the Environmental Protection Agency
(EPA) established the Hazardous Waste Ground-Water Task Force (Task Force)
to address these concerns and to determine the current compliance status of
.the facility in question. The Task Force is comprised of personnel from the
EPA Office of Solid Waste and Emergency Response (OSWER), regional offices,
National Enforcement Investigation Center (NEIC), and state regulatory
agencies. The Task Force is conducting in-depth evaluations of TSD facili-
ties. The following objectives of the Task Force evaluation pertain to a
commercial TSD facility:
0 Determine compliance with interim status ground-water monitoring
requirements 40 CFR, §265, Subpart F, as promulgated under RCRA or the
state counterpart (where the state has received RCRA authorization).
0 Provide information to the EPA to assist in the determination of
compliance with the requirements set forth in the Superfund off-site
policy for selecting hazardous waste management facilities to manage
Superfund hazardous materials.
* Regulations promulgated under RCRA address hazardous waste management
facility operations, including ground-water monitoring, to ensure
that hazardous waste constituents are not released to the environment.
-1-
-------
0 Determine if the ground water contains hazardous constituents.
Fifty-nine (59) TSD facilities were scheduled for ground-water monitoring
system compliance evaluations. The National Enforcement Investigation Center
coordinated and conducted the first evaluation in each of the ten EPA Regions.
Rollins Environmental Services (LA), Inc. (Rollins (LA)) was the sixth Task
Force evaluation in Region VI and was, therefore, coordinated through the
Region. Assistance was provided by the Louisiana Department of Environmental
Quality (LADEQ).
The state of Louisiana was granted phase I interim authorization on ~~
December 19, 1980, to manage and enforce the federal hazardous solid waste
program. The delegated Louisiana Environmental Control Commission (Department
of Natural Resources) then initiated a state hazardous solid waste manage-
ment program under state promulgated regulations (Chapters 1 through 3, and
18) in lieu of the federal regulations promulgated under RCRA (40 CFR Parts
260 through 263, and 265).
On January 24, 1984, the state of Louisiana was granted phase II, Part
A, B, and C, interim authorization to issue solid waste permits and to
continue to manage and enforce the federal hazardous solid waste program.
The Louisiana Environmental Control Commission reorganized, and the present
Louisiana Department of Environmental Quality obtained the responsibility
of managing the state hazardous solid waste management program, with the
additional state promulgated regulations, in lieu of the federal regulations.
The state of Louisiana was granted final authorization to regulate the
hazardous solid waste program on January 18, 1985.
-2-
-------
The Hazardous Waste Ground-Water Task Force evaluation of the Rollins
(LA) site was conducted in conformance with the state of Louisiana regula-
tions; Louisiana Hazardous Waste Regulations, Chapter 23, Subchapter V.
In order to achieve the objectives of the Hazardous Waste Ground-
Water Task Force, the evaluation of Rollins (LA) consisted of:
1. An extensive review of the Rollins (LA) data concerning the;
a. Ground-water sampling and analysis plan.
b. Ground-water quality assessment plan or program (as appropriate).
c. Regional and site geology.
d. Regional and site ground-water hydrology, including hydraulic
gradients (naturally and/or artificially induced), velocities,
pathways, etc.
e. Ground-water monitoring well locations, construction (drilling,
completion, and development), and function of the ground-water
monitoring wells.
f. Ground-water sampling procedures including collection, handling,
documentation, shipping, chain of custody, equipment, and quality
assurance/quality control.
g. Existing analytical data resultant of ground-water monitoring
activities.
h. Types and volumes of waste stored, treated, and/or disposed.
i. Current and past site activities and uses including identification
of prior releases (pre-RCRA) of hazardous constituents.
j. Design and construction information on units and areas containing
solid waste.
k. Existing or planned site modification or remedial measures.
-3-
-------
2. An evaluation of the information discussed in 1. a.- k. to determine
the status of the Rollins (LA) ground-water monitoring system and
activities regarding compliance with the applicable regulations for
all aspects of the ground-water monitoring program objectives.
3. An on-site facility inspection was conducted to:
a. Review Rollins (LA) site documents and records.
b. Evaluate Rollins (LA) present ground-water sample collection,
handling, and analytical techniques and procedures.
c. Evaluate the RCRA ground-water monitoring wells for proper
placement and construction.
d. Locate and identify past and present TSD units and areas.
e. Obtain representative ground-water samples from select RCRA
monitoring wells.
f. Obtain representative samples from other areas, as necessary,
to aid in identifying contaminants in the ground water.
Splits of all samples collected by the Task Force were offered to
Rollins (LA).
All aspects of the Hazardous Waste Ground-Water Task Force were conducted
in conformance with the:
RCRA Ground-Water Monitoring Technical Enforcement Guidance Document,
United States Environmental Protection Agency; Office of Solid Waste
and Emergency Response, OSWER - 9950.1, September 1986.
Protocol for Ground-Water Evaluations, United States Environmental
Protection Agency, Hazardous Waste Ground-Water Task Force, OSWER -

Summary of the Rollins (LA) Site
Rollins Environmental Services (LA), Inc. is an interim status commercial
hazardous solid waste management facility that specifically treats, stores, and
disposes of solid and hazardous waste (EPA ID #LAD010395127). The Rollins (LA)
property presently consists of approximately three hundred forty-five (345)
acres and is located in Section 48, Township 5S, Range 1W, in East Baton Rouge
Parish, Baton Rouge, Louisiana (reference Figure 1).
The present facility operations for the management of the RCRA hazardous
wastes include landfill ing with waste stabilization of noncombustible wastes
and nonrecoverable organics and inorganics; wastewater treatment through
chemical, biological, and physical methods; and high temperature incineration
of nonrecoverable organics. Storage, recovery, laboratory analyses, and
transportation at the Rollins (LA) site accommodate these disposal processes.
Since 1981, Rollins (LA) has not accepted polychlorinated biphenyls (PCB's),
dioxins, explosives, radioactive wastes, or infectious wastes.
Rollins (LA) has been in continuous operation since 1969. Treatment,
storage, and disposal have previously been accommodated by approximately one
hundred eight (108) solid waste management units located on the original
two hundred two (202) acre tract of the Rollins (LA) property (reference
Figure 2). Rollins (LA) acquired a seventy-two (72) acre tract of adjacent
land west of the site (Western tract) in early 1982, and a seventy-one (71)
acre tract of the Allied Corporation Fibers and Plastics Co. (Allied north
tract) in February 1985 (reference Figure 3).
The treatment, storage, and disposal units consisted of landfill cells,
treatment basins, barrel cells, an acid gel cell, a carbon cell, an acid pit,
neutralization basins and various miscellaneous units (the identification

numbers assigned to each individual unit were not utilized to provide classi-
fication and records of the specific contents in each unit). Hazardous
wastes were also eradicated by various on-site treatment processes and incin-
eration. The majority of the storage, treatment, and disposal units were
completed below grade and were typically unlined. Also, a large inactive
landfarm is located on the eastern portion of the Rollins (LA) site (reference
Figure 2).
On April 22, 1980., the Louisiana Environmental Control Commission issued
an Order of Performance Guidelines and Schedule for Compliance to Rollins (LA).
The order required the upgrading of the landfarm, incineration, biological
treatment system, receiving and storage areas, and landfill operations. The
upgrading of the landfill operations included the installation of a ground-
water monitoring system. If the presence of contaminants were indicated
in the ground water, a corrective action plan was to be drafted for review
and implementation. As a result, twenty-one (21) ground-water monitoring
wells were installed in December 1980 at various depths within the uppermost
aquifer (reference Figure 4). Subsequently, the presence of contaminants
were detected in the ground water beneath the Rollins (LA) site, and a correc-
tive action ground-water monitoring and recovery program was initiated. The
ongoing ground-water recovery program is currently in operation. Presently,
Rollins (LA) is involved in an assessment ground-water monitoring program
for the entire site due to the presence of contaminants in the ground water.
The assessment ground-water monitoring wells are comprised of the original
twenty-one (21) wells and additional monitoring wells subsequently installed
(reference Figure 5 for the present assessment ground-water monitoring system).

To alleviate the probable sources of the contaminants present in the
ground water, Rollins (LA) initiated the task of excavating the contents of
the majority of the landfills, treatment basins, storage and other miscel-
laneous units. The status of these treatment, storage, and disposal units
at the time of the Task Force evaluation varied from active, inactive and
covered, to excavated and capped. The operation dates of these units varied
widely from one month to a significant number of years.
Remediation of these units commenced in 1980. The order issued April 22,
1980, was subsequently amended on or_about-May 4, 1982, and required Rollins
(LA) to provide additional information concerning the finalization of the
*-
remediation process of the treatment, storage, and disposal units. Many of
the units have undergone excavation and closure, although, a number of the
units received intermediate remediation prior to a subsequent final closure
(reference Appendix A). To date, only inactive landfill cells 611B, 619, and
719 (all located at the western limit of the Rollins (LA) site), the inactive
Hy Purle landfill and the inactive landfill south of the equalization basin
302 remain intact (reference Figures 2, 3, and 6).
Construction commenced November 1980 on subcell A of the sole RCRA hazardous
waste landfill, cell 717. Subsequently, subcell B was constructed and commenced
operation in November 1982, subcell C was constructed and commenced operation in
November 1983, and subcell D was constructed and commenced operation In mid 1984.
Presently, only the southern portion of subcell A and the eastern portion of
subcell D are active. The remaining sections of the A and D subcells are currently
inactive, as well as subcells B and C. The construction of landfill 717 coin-
cided with the remedial action in progress of prior treatment, storage, and
disposal units. Several of the Rollins (LA) site storage and treatment basins
remain in service to accommodate current on-site facility processes.

Subsequent to the issuance of the April 22, 1980, compliance order,
Rollins (LA) and the Louisiana Environmental Control Commission negotiated
an agreement of settlement on June 17, 1981, concerning the landfarm operation.
Within six months of the settlement date, Rollins (LA) agreed to cease oper-
ation of the landfarm. The landfarm exclusively accommodated the disposal
of a listed hazardous waste generated by a Baton Rouge facility. The generator
of this waste was subsequently granted a deli sting of the hazardous waste to
a nonhazardous status by the Environmental Protection Agency. Rollins (LA)
did cease operation of the landfarm by late December 1981.
On October 12, 1984, the Environmental Protection Agency (Region VI)
issued Rollins (LA) an administrative order pursuant to the authority of
Section 3013 of RCRA. The order required further ground-water monitoring,
sampling and analyses, and reporting to establish the the extent of the
contaminants detected in the ground water. As a result of the requirements
of the order, Rollins (LA) submitted a schedule of closure of the inactive
Hy Purle landfill, acquired the Allied north tract (seventy-one (71) acres)
in February 1985, and conducted a study to determine whether the contaminants
detected in the ground water had migrated beyond the Rollins (LA)/Allied
north tract property line. The conclusions of this study indicated that
the contaminants present in the ground water beneath the Rollins (LA)
site had not migrated off-site. The requirements of the order were deemed
completed by the Environmental Protection Agency (Region VI) on May 2, 1985.
Concurrent with the October 12, 1984, order, the Environmental Protection
Agency (Region VI) issued Rollins (LA) a Compliance Order and Notice of
Opportunity for Hearing on November 20, 1984. This order was issued pur-
suant to the authority of Section 3008 of RCRA and addressed areas of non-
-14-
-------
compliance regarding required notifications, facility operations, and
ground-water monitoring and assessment. Subsequently, on July 14, 1985,
the Environmental Protection Agency (Region VI) issued a Consent Agreement
and Final Order to Rollins (LA) for the above-mentioned November 20, 1984,
order. Subsequently, the requirements of the order where completed by
Rollins (LA).
On May 13, 1986, the Louisiana Department of Environmental Quality
issued Rollins (LA) a Compliance Order pursuant to La. R.5.3; 1051. This
order required Rollins (LA) to address the integrity of, and the presence
of contaminants in the landfill 717 leak detection system. Rollins (LA)
response to this order was in preparation at the time of the Task Force
evaluation; therefore, the final status of the order was pending.
In 1985, Rollins (LA) commenced construction on an additional RCRA
hazardous waste landfill, cell 901. Landfill 901 is located in the south-
west corner of the western and southern property lines of the original
tract of the Rollins (LA) land (reference Figure 3). Operation of the
landfill is scheduled for early January 1987. Landfill 901 is located
within the limit of the waste management area; therefore, the current
assessment ground-water monitoring system will accommodate landfill 901.

Summary of Conclusions
The conclusions of the Hazardous Waste Ground-Water Task Force November 10
through 20, 1986, evaluation of the Rollins Environmental Services (LA), Inc.
are presented below:
A. The following regulatory deficiencies were recognized:
1. Assessment Ground-Water Monitoring System (LA 23.37(h))
The data presented by Rollins (LA) indicates that the placement
of the ground-water monitoring wells at and beyond the downgradient
limit of the site waste management area were not sufficient to have
fully defined the extent of the contaminants present in the ground
water beneath the Rollins (LA) site. The assessment ground-water
monitoring system requires upgrading to adequately assess the extent
of the contaminants. This will provide for the adequate detection
and continued monitoring for the presence of contaminants.
The present assessment ground-water monitoring system monitors
the limits of the site waste management area which Rollins (LA) has
defined as their original site property perimeter. For ease of
discussion, the Task Force has designated two (2) waste mangement
areas within the overall site waste management area; 1) the landfill
717/901 waste management area, and 2) the equalization basin 302/
inactive Hy Purle and inactive south landfills waste management
area (reference Figure 3).
The southern limit of the landfill 717/901 waste management
area is approximately fifteen hundred (1,500) feet in length. Five
(5) ground-water wells monitor the A zone at the southern limit of
-16-
-------
the waste management area. The depositional nature of the sediments
and the infrequency of placement of the A zone ground-water monitoring
wells, support the inefficiency of these wells to adequately assess
the extent of the contaminants that have been detected in the A zone
at these well locations.
The BI zone is monitored by four (4) ground-water wells at the
southern limit of the landfill 717/901 waste management area. The
infrequency of the placement of monitoring wells in the Bj zone can-
not provide adequate assessment of the extent of contaminants, or the
continued monitoring of the migration of the plume of contaminants.
Several monitoring wells, located beyond the southern limit of the
landfill 717/901 waste management area, also cannot provide adequate
assessment of the extent of contaminants that have been detected in
the B1 zone at the southern limit of the waste management area. The
B£ zone is monitored at the southern limit of landfill 717/901 waste
management area by one (1) well. The presence of contaminants have been
detected in the ground water at this location. The B£ zone is not
adequately monitored at the southern limit of the waste management area.
The C zone is not monitored for the entirety of the southern limit
of the landfill 717/901 waste management area. The C zone is present
within the uppermost aquifer at the southern limit of the waste manage-
ment area, and the presence of contaminants have been detected in the
overlying A, Bj and 62 zones. The status of the entire C zone along
the southern limit of the waste management area remains unknown.
-17-
-------
The western limit of the landfill 717/901 waste management area
is approximately fifteen hundred (1,500) feet in length. The A and
BI zones are monitored at only two (2) well locations. These two
(2) zones are not monitored for the remainder of the western limit
of the waste management area. The B£ zone is not monitored for the
entirety of the western limit limit of the waste management area.
The present monitoring system cannot provide adequate assessment
of the extent of the contaminants that have been detected in the A
and B1 zone at the western limit of the waste management area. The
status of the 62 zone along the western limit of the waste manage-
ment area remains unknown.
The C zone is monitored at one well location at the western limit
of the landfill 717/901 waste management area. Contaminants have
not been detected at this location; however, the C zone is present
within the uppermost aquifer and the presence of contaminants have
been detected in the overlying A, B} and 62 zones spanning the
Rollins (LA) site. The status of the C zone at the western limit
of the waste management area remains unknown.
The southern limit of the equalization basin 302/inactive Hy
Purle and inactive landfills waste management area is approximately
six hundred (600) feet in length. The A, Bg and C zones are moni-
tored at the southern limit of the waste management area with one
monitoring well cluster. The A, 82 and C zones are not monitored
for the remainder of the southern limit of this waste management area.
The BI zone is not monitored for the entirety of the southern limit
of the waste management area, either. The monitoring well cluster
-18-
-------
cannot provide adequate assessment of the extent of the contaminants
detected in the A, B2 and C zones for the entirety of the southern
limit. The status of the B} zone remains unknown for the entirety
of the southern limit of the waste management area. One (1) monitor-
ing well located beyond the southern limit of the waste management
area cannot provide adequate assessment of the extent of the contam-
inants that have been detected in the A and BJ zones at the southern
limit of the waste management area.
2. The present October 1986 sampling and analysis plan (reference Appendix B)
does not adequately describe the present monitoring program for the
assessment ground-water monitoring system (LA 23.36(a)), specifically:
a. The sampling and analysis plan does not reflect the following
information; the ground-water monitoring program in effect, the
ground-water monitoring wells utilized, the upgradient ground-
water monitoring wells, and the ground-water sample collection -
schedule, and the parameters for analyses.
b. Much of the data presented in the sampling and analysis plan
regarding the ground-water monitoring well elevation and con-
struction data is not up to date, therefore, incorrect values
are referenced.
Many other discrepancies between the October 1986 sampling and
analysis plan and the actual Rollins (LA) sample collection, pre-
paration, and shipment procedures observed in the field were also
noted and are further discussed in the section concerning the
interim status ground-water sampling and analysis plan.
-19-
-------
B. The following technical deficiencies were recognized:
1. The geology and ground-water hydrology of the Rollins (LA) site
requires further characterization, specifically:
a. The complete extent of the C zone at the limit of and beyond
the site waste management area has not been determined.
b. The hydraulic interconnection or isolation of the permeable
beds within the Scott's Bluff Formation has not been verified.
c. Accurate representation of the hydraulic conductivities
(in-situ field testing) of the A, Bj, 62 and C zones of
the Scott's Bluff Formation have not been provided.
d. The velocity and direction of the ground-water flow within
the A, Bj, %2 and C zones has not been adequately deter-
mined.
2. The ground-water monitoring wells were generally installed
(drilling and completion) with suitable procedures to obtain
representative samples of the ground water. However, the follow-
ing well record and maintenance deficiencies may influence the
quality of a ground-water sample:
a. Lack of or improper routine maintenance of the ground-water
monitoring wells. The Task Force field measurements of the
total depth of the wells indicates that several of the ground-
water monitoring wells have total well depths (as recorded
at the time of well construction) that exceed the current
total depth of these respective wells (at the time of the
-20-
-------
Task Force measurements). This can be indicative of sedi-
ment build-up and/or well casing failure. These conditions
may hinder the collection of .a ground-water sample from the
appropriate formation bed and also influence the quality of
the ground-water sample that is collected.
b. Lack of maintaining complete documentation of the installation
(drilling and completion) and maintenance of the ground-water
monitoring wells. The quality of the ground-water sample may
be influenced by faulty installation and/or maintenance.
3. The ground-water sample collection, preparation, and shipment
procedures practiced by the Rollins (LA) personnel were generally
acceptable for obtaining representative ground-water samples.
The following should be considered in future ground-water sampling
activities:
a. Safety procedures should be stressed and applied when collect-
ing and preparing ground-water samples.
b. The total depth of the ground-water monitoring wells should
be measured during each scheduled sampling event to ensure
the integrity of the well.
c. The initial set of ground-water samples collected should be
for the analyses of the presence of the organic constituents
(volatiles, semi-volatiles, TOC, and TOX) due to the volatil-
ization sensitivity of these parameters. This will ensure
a representative sample of the ground-water sample for the
analyses of these parameters.
-21-
-------
The analytical results, of the samples collected at the time of the
Hazardous Waste Ground-Water Task Force evaluation, indicated the presence
of contaminants in several of the ground-water wells, the landfill 717
leachate, and in the liquid from the leak detection system (reference
Appendix C). The samples collected were analyzed for the presence of
the parameters which comprise the Hazardous Substances List, as well as,
various metals and inorganics (reference Appendix D):
1. Organics
a. Ground water, liquids, and leachate were collected at the
locations of select ground-water wells, landfill 717 leak
detection wells, and a landfill 717 leachate collection well.
The presence of contaminants '(organics) were detected above
the contract laboratory detection limits at the following
we!Is*:
6B, I3
IDA DC (leak detection)
11A Dy
13A Landfill 717 leachate
13B}
In reference to this document, the presence of contaminants is
limited to organics (volatile, semi-volatile, and pesticides

Regional Hydrogeology1
The Baton Rouge area lies at the southern end of the Mississippi
embayment. This structural/stratigraphic feature is a broad syncline
that plunges towards the Gulf of Mexico and merges with the Tertiary
Gulf Coast geosyncline. Sediments in the embayment range in age from
Jurassic to Quaternary, but the important hydrogeologic sections in the
study area are primarily of Miocene age or younger.
The Rollins (LA) site is located on Pleistocene age Mississippi
River terrace deposits. These deposits are locally referred to as the
Scott's Bluff Formation. The "shallow aquifers" of this area occur in
Pleistocene alluvial terrace deposits and obtain total thicknesses rang-
ing from one hundred (100) to two hundred fifty (250) feet. These sedi-
ments are clays, silts, sands and gravels, and are of limited use as
water supply sources.
Beneath the alluvial terrace deposits is a thirty-one hundred (3,100)
foot section of alternating sands and clays that make up the freshwater
bearing section of the area. These fluviodeltaic sediments are of Miocene,
Pliocene, and Pleistocene ages and are divided into the Hattiesburg, Pasca-
goula, and Citronelle Formations, respectively. This section consists of
eleven (11) sands which range in thickness from twenty feet (20) to three
hundred (300) feet and are separated by clay beds. These sands are col- -
lectively referred to as the Southern Hills aquifer system, however, each
sand has been named according to depth (i.e., the "400-foot sand", the
See references following this document.
-24-
-------
"600-foot sand", and so forth). The intervening clay layers range from
several hundred feet to nonexistent, which results from the merging of the
sand bodies. These sands dip south to southeast at an average rate of
fifty (50) feet per mile.

Site Hydrogeology
Rollins (LA) has principally retained the services of Geraghty & Miller,
Inc. (Baton Rouge, LA) from approximately April 1980 to the present. The
site hydrogeology, herein described in this section, represents an interpre-
tation by Geraghty & Miller, Inc. for Rollins (LA).
Geraghty & Miller Inc. have conducted various site studies commencing
in approximately April 1980. The initial study was to determine the instal-
lation of a hazardous waste ground-water monitoring system. Additional
studies have addressed site hydrogeology, the presence of contaminants in
the ground water, the velocity and extent of the contaminants in the ground-
water, and the corrective action program (ground-water recovery). The
hydrogeology described in this report is resultant from information obtained
from reports addressing the aforementioned studies. The Geraghty & Miller,
Inc. data base consists of approximately three hundred fifty (350) cored
soil borings of which several extend to one hundred fifty (150) feet in
depth. The data base also includes laboratory tested hydraulic conductivities
(constant and falling head laboratory procedures) of approximately one
hundred sixteen (116) select core samples, in-situ testing for hydraulic
conductivity values at three (3) soil borings, grain size distribution
sieve analyses of fifty (50) select samples, and the cation-exchange capacity
on twenty-four (24) select clay samples.
Geology:
Rollins (LA) is located on a regional terrace which is locally known
as Scott's Bluff. Scott's Bluff is at an elevation of approximately seventy-
five (75) to eighty (80) feet above mean sea level (msl) and consists of
-26-
-------
fine grained fluviodeltaic deposits to approximately one hundred eighty-
five (185) feet below land surface (approximately 105 feet msl). These
deposits are known as the Scott's Bluff Formation. The upper one hundred
eighty-five (185) feet consist predominantly of stiff gray and tan clays
and silty clays that exhibit mottling and contain organic debris, ferruginous
and calcareous concretions. Permeable, discontinuous beds of silts and
fine sands are present within the clays. These clays and permeable zones
that extend to a depth of one hundred eighty-five (185) feet have been
categorized into four distinct saturated zones designated as the A, Bi,
B2 and C zones (reference Figures 7 through 10 for the distribution of
these zones beneath the Rollins(LA) site). Each of the four zones exhibit
permeable beds.
The A zone permeable beds are typically encountered between twenty
(20) and forty (40) feet below land surface and consist of clayey silts,
sandy silts, silts and/or fine sands that are thin and discontinuous. The
uppermost twenty (20) feet of this zone is generally clay which exhibits
the characteristics of the clays described in the aforementioned paragraph.
This zone tends to have a discontinuous northwest/southeast trend of a
thicker, permeable silt and/or sand across the northeast section of the
Western tract transversing the western portion of the Rollins (LA) site
proper, and continuing through the eastern half of the Allied tract. These
discontinuous beds of silt and/or sand can generally yield less than one
(1) gallon per minute (gpm) up to ten (10) gpm. In most areas, the A zone
is separated from the upper B} zone by a stiff silty clay bed.

The B zone is divided into a Bj and B2 zone of which each exhibits
one or more permeable bed. The more permeable beds within each zone are
generally separated by a stiff clay and/or silty clay. The Bj zone is
typically encountered between forty (40) and seventy (70) feet below land
surface and consists of clay, silt, and/or sand. This zone trends southwest
to northeast across the central and southern portions of the Rollins (LA)
site. With the exception of a few, the more permeable silts and sands tend
to be less than twenty (20) feet in thickness. The Bj zone is generally
separated from the A zone by clay beds.
The B£ zone is typically encountered between seventy (70) and one
hundred (100) feet below land surface and consists of clay, silt, and/or
sand. This zone is present through the southern half of the site and
tends to be more extensive and permeable adjacent to the south Rollins
(LA)/Allied north tract property line. The B£ zone is isolated from the
C zone by ten (10) to forty (40) feet of a stiff clay to silty clay. The
B£ zone is not in direct hydraulic connection with the C zone due to
separation by clay beds.
The C zone is typically encountered at one hundred ten (110) feet
below land surface and consists of a permeable fine to course sand.
It does not appear that the C zone is present in the southwestern portion
of the site. Soil borings that were completed to a depth greater than one
hundred thirty-eight (138) feet in this area did not encounter the C zone
sand bed.

Hydraulic Gradient:
The direction of ground-water flow was determined from a data base
of water level measurements collected from 1981 to the present. The data
base has expanded on several occasions with the installation of additional
ground-water monitoring wells, observation wells, and/or piezometers
(reference Figure 11). The ground-water flow directions are obtained
for each of the four zones monitored. Currently, water level measurements
of the A, Bj, B2 and C zones are obtained from the following wells:
A zone - 1A, 2A, 3A, 4A, 5A, 6A, 7A, 8A, 10A, 11A, 12A, ISA, 14A,
15A, 16A, 20A, SMS
Bj zone - ISj, 5Blt 6B1§ 88}, lOBj, HBj, ISBj, 14B1} 15Blf
B2 zone - 4Bj, 4B2, 17B}, 17B2
C zone - 1C, 4C, 9Cr, 11C, 14C
The direction of ground-water flow in the A, Bj, B2 and C zones is
generally to the west/southwest. The elevation of the ground water tends
to be higher in the first and second quarter of each year (January through
June). A depression in the ground-water elevation in the area of the
Roll ins(LA)/ATI ied northern tract property line is reflected in the data
obtained from the A, B-^ and B2 zones. This depression is resultant of
the dewatering process at the active landfill 717 and the removal of the
ground water by the interceptor wells, Ij through 1 5 (ground-water
recovery wells). The direction of flow in this immediate area is towards
these two sources. The direction of ground-water flow in the C zone tends
to be more southerly. This could be due to that the two major aquifers that
are below the one hundred eighty-five (185) feet of section previously
discussed are pumped at significant rates south of the Rollins (LA) site.

Velocity of Ground-Water Flow:
The velocity of ground-water flow in each of the four zones monitored
was determined utilizing Darcy's Law (Vh=ki/n) where:
Vh = horizontal velocity
k = hydraulic conductivity
i = hydraulic gradient
n = effective porosity
The major sedimentary units underlying the site were divided into six (6)
sections in reference to the hydraulic conductivity of each one:
1. clay, compact k=lxlO-10 and 1x10-9 cm/sec
2. clay trace of silt k=lxlO-5 and 1x10-7 cm/sec
3. clay, silty k=lxlO-6 on/sec
4. silt, clayey k=lxlO-5 cm/sec
5. sand, very fine, sli'ghtly k=lxlO-4 on/sec
silty or clayey
6. sand, fine to medium k=lxlO-3 cm/sec
These values were consolidated from approximately one hundred
sixteen (116) select soil core samples. The hydraulic conductivities of
these samples were determined in the laboratory utilizing the falling and
constant head test methods. In determining the velocity of ground-water
flow of the A, Bj, B^ and C zones, the hydraulic conductivity of each
particular zone was increased an order of magnitude higher to compensate
in the event that the most permeable bed had not been laboratory tested.
The effective porosity in the facility area ranges from 0.2 to 0.35. The
lower values (0.15-0.25) were used in determining the velocities as this
would contribute to an overall greater value for the velocity. The hori-
zontal velocities of ground-water flow have been estimated at 3 feet per
-35-
-------
year (ft/yr) to 4.5 ft/yr in the A zone, 10 ft/yr in the Bj zone, 10
ft/yr in the B2 zone, and 8 ft/yr in the C zone. The vertical velocity
Vv=(k)dh/(n)m was estimated at .003 ft/yr for ground-water flow from the
B£ zone downward to the C zone, and at 0.048 ft/yr for flow from the C
zone upward to the 62 zone:
Vv = vertical velocity
k = hydraulic conductivity
dh = difference in water levels of the B2 and C zones
n = effective porosity
m = thickness of clay between the B2 and C zones
Definition of the Uppermost Aquifer:
The ground-water monitoring system consists of wells monitoring the
saturated A, Bj, B2 and C zones. The permeable beds within the A zone
have been defined as the uppermost aquifer beneath the Rollins (LA) site,
Where these A zone beds are absent, the permeable beds within the B zone
are then considered the uppermost aquifer.
The uppermost major water supply aquifer beneath the site is the
"400 ft" sand of which the Rollins (LA) water supply well is completed
into. The top of this sand is encountered at approximately one hundred
eighty-five (185) feet below land surface. This aquifer is isolated
from the C zone by approximately fifty (50) feet of clay, thus, isolated
from the A, BI and B2 zones as well.

Evaluation of the Rollins (LA) Site
Hydrogeologic Characterization
As a result of the Task Force evaluation of the available hydrogeologic
data, it has been determined that Rollins (LA) has not sufficiently charac-
terized the geology and ground-water hydrology of the site. Specifically,
the Task Force concluded that:
1. The following hydrogeologic characteristics of the aquifer have
not been fully identified:
a. The complete extent of the C zone at the limit of and beyond
the site waste management area has not been determined.
b. The hydraulic interconnection or isolation of the permeable
beds within the Scott's Bluff Formation has not been verified.
c. Accurate representation of the hydraulic conductivities (in-
situ field testing) of the A, Bj, Bg and C zones of the
Scott's Bluff Formation have not been provided.
d. The velocity and direction of the ground-water flow within the
A, Bj, B2 and C zones has not been adequately determined.
The C zone sand is fairly extensive across the Rollins (LA) facility.
The top of the zone appears to increase in depth below land surface towards
the eastern area of the site. In reference to the depth at which the top is
typically encountered (approximately one hundred ten (110) feet), Rollins
(LA) describes the absence of this zone in the southern portion of the Western
tract transversing the southwest corner of the original Rollins (LA) tract,
and in the entire western half of the Allied north tract. Reference Figure 10.
-37-
-------
the cores tested are not exclusive to any one of the permeable sections within
each of the four (4) zones, therefore, resultant values could be biased.
The characteristic of the depositional environment of sediments beneath
the Rollins (LA) site generally display intermittent sands and silts within
the Scott's Bluff Formation clays across the site. The presence and absence
of particular sediment deposition can occur over a brief distance. Available
data indicates the silt and sand beds within the A, Bj, B£ and C zones beneath
the site appears to increase in frequency of occurrence in a westward/southwestward
direction transversely the site. Grain size analyses, performed by Geraghty
& Miller, Inc. indicates a higher percentage of silt and sand content in
these sedi-nents in the westward direction, also. These silt and sand beds
appear to decrease in thickness as frequency of occurrence increases. The
permeable beds within the A, Bj, 62 and C zones are extensive in the area
beneath the Rollins (LA) site. Many of these beds extend beyond the li.iit
DC i'i2 site waste management area. This results in many variations of the
composition of the seciinents, therefore, increasing the frequency for the
determination of hydraulic conductivity values for adequate representation.
Rollins (LA) has not provided adequate hydraulic conductivity values with
respect to composition and spatial distribution of the beds encountered
within the four zones. All the A and Bj zone beds (clays and permeable
beds) appear to have been tested for hydraulic conductivity values. The
location of cored soil borings representing the A zone are somewhat restricted
to the Allied north tract and the inactive Hy Purle landfill area. No cores
have been obtained at the location of the present landfill 717/901 area or
at the linit of the waste management area. This is also indicative of the
cored soil borings in the Bj zone with the following exception, the borings
do extend into the location of the two (2) landfills. Only one (1) soil
-40-
-------
boring was cored into the A and Bj zone in the Western tract. This soil
boring was completed in the southernmost section of the tract, an-| th-jre^o
does not provide adequate representation of the hydraulic conductivities
that may be encountered across this tract. The Bg zone is represented
by three (3) cored soil borings which are located upgradient (east) of
the active landfill area. This zone has not been sufficiently represented
regarding hydraulic conductivities for all the beds encountered, as well
as, the spatial distribution of the cored soil borings in this zone do
not adequately encompass the entire site. This is particularly evident
at the limit of the landfill 717/901 and equalization basin 302/inactive
Hy Purle and inactive south landfills waste management areas, and the
extent beyond. The C zone is represented only by six (6) cored sections
of two (2) soil borings at the location of the upgradient ground-water
monitoring wells 1A, IB and 1C. This one (1) boring is inadequate in
that the C zone is not represented at the limit of the waste management
areas, as well as, any changes in the hydraulic conductivity due to the
variations observed in this zone across the site.
In Spring 1985, Rollins (LA) conducted three (3) in-situ hydraulic
conductivity tests in conjunction with a characterization study of the
Western tract. The A zone clay was selected for testing at the three (3)
soil boring locations. Values of 10~6 were resultant for all three (3)
of the exercises conducted. These in-situ tests do not fully describe
the hydraulic conductivities of the A zone beds for the entire site.
In-situ tests were not conducted in the 81, B^ and C zones.
-41-
-------
Rollins (LA) has periodically provided horizontal ground-water flow velo-
cities of the A, Bj, B£ and C zones within the uppermost aquifer beneath
the Rollins (LA) site. Vertical ground-water flow velocities have been
provided from the B£ to C zone at the location of the MW 1 well cluster and
from the C to B£ zone at the location of the MM 4 well cluster (flow is up-
ward from the C to the B£ zone due to ground-water recovery in the overlying
B£ zone).
The ground-water (horizontal and vertical) flow velocities of the four
(4) zones were determined utilizing Darcy's Law (Vh = ki/n), where;
Vh = horizontal velocity
k = hydraulic conductivity
i = hydraulic gradient
n = effective porosity
and Vv = (k) dh/(n)m;
Vv = vertical velocity
k = hydraulic conductivity
dh = difference in water levels of B 2
and C zones
n = effective porosity
m = thickness of clay between the B2
and.C zones
The ground-water flow velocities of the A, Bj, B2 and C zones were
determined under several circumstances imposed by Geraghty & Miller, Inc.
An order of magnitude higher was used to compensate in the event that the
most permeable bed had not been laboratory tested. The effective porosity
-42-
-------
in the facility area ranges from 0.2 to 0.35. The lower values (0.15-0.25)
were used in determining the velocities, as this would contribute to an
overall greater value for the velocity.
In several documents, Geraghty & Miller, Inc., has stated that the result-
ant ground-water flow velocity values are to provide an idea of the general
order of magnitude and should not be applied to detailed site specific assess-
ments. The hydraulic conductivity and effective porosity values are not
representative of the actual characteristics of the sediments beneath the
Rollins (LA) facility. It has not been explained if various site activities,
the ground-water recovery system, and/or if the seasonal ground-water level
variations have an effect on the ground-water flow velocities and direction.
Until this has been determined, adequate assessment of the plume of contami-
nants cannot be conducted.

Chronology of the Interim Status Ground-Water Monitoring System1
1980
Rollins Environmental Services (LA), Inc. installed twenty-one (21)
ground-water monitoring wells in December 1980 through January 1981
(reference Figure 4). These wells were installed in response to an Order
of Performance Guidelines and Schedule for Compliance issued April 22, 1980,
by the Louisiana Environmental Control Commission. Each of the twenty-one
(21) ground-water monitoring wells were completed into one (1) of the three
(3) Geraghty & Miner, Inc., designated zones (A, R and C) within the upper-
most aquifer in the Scott's Bluff Formation. Permeable beds are present
within the three (3) zones.
A zone 10 wells screened interval between 30 to 40 feet
B zone 7 wells screened interval between 50 to 80 feet
C zone 4 wells screened interval between 115 to 125 feet
The upgradient and downgradient wells were designated as follows
(reference Figure 4).

the upper B, zone forty (40) to seventy (70) feet and the lower B2 zone
seventy (70) to one hundred (100) feet.

rnsse nonitoring wells were sampled in January 1981 and the ground
water wr.s d!i.i"!y!?1 for the metals; arsenic, cadmium, copper, lead, mercury,
nickel, selenium, and zinc.
1981
The analytical results indicated that the Environmental Protection Agency
interim primary drinking water standards were exceeded in the ground water
at the location of Ml-! SBj for selenium, and MW 11C for cadmium. The moni-
toring wells that are cy:n;>leted into the A zone at'these locations (MW 8A '
and MW 11A) did not indicate a significant concentration of these metals.
Rollins (LA) claimed the concentrations indicated were resultant of a labor-
atory error or an introduction from an outside source. As a result of these
analyses, ground water was again obtained (February 1981) from the ground-
water Mionito^inj ,'^lls and analyzed for the presence of total volatile organic
compounds (VOC's) and metals. Water levels were obtained also. Later in
February 1981, analyses for organics (VOC's on the Hazardous Substance List
(HSL)) were conducted on ground water from all the monitoring wells except
MW's 4C and 11A. The analyses of the late February 1981 sampling of ground
water inji-.t; j ' - i j'i i r:,-;a-T: csicentrations of VOC's in MW's 8A and 8B^, MW
-45-
-------
1A, and MVJ 68^ Rollins (LA) stated that MW's 4A and 4Bj indicated con-
tamination to the ground water from the facility and contaminants in MW's
1A and 6Bi were probably introduced during the drilling and completion of
the ground-water monitoring wells. No explanation was provided by Rollins
concerning the contaminants present in MW's 8A and 8Bj. In March 1981, the
Louisiana Department of Environmental Quality requested Rollins (LA) to con-
duct the following additional sample parameters; purgeable organic compounds,
acid extractable organic compounds, base/neutral extractable organic compounds,
antimony, beryl!iun, cyanide, and poTychlorinated biphenyls (PCB's).
To maintain compliance with the April 22, 1980 order, Rollins (LA) imple-
mented a corrective action ground-water monitoring program in September 1981.
This monitoring program consisted of monthly and some bimonthly sampling of
any ground-water monitoring wells that were indicating the presence of con-
taminants. The ground water from these wells was analyzed for VOC's. All
other monitoring wells were sampled on a quarterly schedule and analyzed for
the parameters listed in Table A. Water levels were also obtained at the
time of sample collection. The VOC's were determined to be the most appro-
priate indicator parameters for the presence of contaminants to the ground
water.
An integral part of the corrective action program was the installation
of two (2) ground-water recovery wells; interceptor wells Ij and 12 (reference
Figure 12). These two (2) recovery wells were installed in September 1981 and
are located upgradient of MW's 4A and 4Bj. Interceptor well Ij, which did
not commence operating until October 1981, is screened seventy-three (73) to
eighty-three (83) feet below land surface and removes contaminated ground
water from the same formation bed in which MW 4B1 is screened. Interceptor

well I2 is screened thirty-two (32) to forty-seven (47) feet below land
surface and removes contaminated ground water from the same formation bed
in which MW 4A is screened. The ground water recovered from both intercep-
tor wells is analysed for the presence of VOC's.
1982
In early 1982 Rollins (LA) acquired the Western tract (approximately
seventy-two (72) acres) to accommodate future landfill expansion.
In May and June of 1982, ten (10) ground-water monitoring wells were
installed on the neighboring Allied Corporation Fibers and Plastics Company
(Allied Corporation) north tract (reference Figure 5). Allied Corporation
designated these monitoring wells as SMI through SM6 of which the screened
intervals are between twenty-seven (27) to forty (40) feet, and DM1 through
DM4 of which the screened intervals are between sixty-six (66) to eighty-
five (85) feet. Following well completion in June 1982, ground water from
the wells was analyzed for the presence of the parameters listed in Table B.
Only monitoring well SMS indicated the presence of contaminants with the
presence of benzene at 0.750 milligrams/liter (mg/1) and toluene at 0.78
mg/1. An assessment by Rollins (LA) of the presence of the contaminants
detected in SMS was subsequently conducted in February 1983. The assess-
ment included the installation of MW 12A as an observation well (reference
Figure 5). Monitoring well 12A did detect the presence of contaminants
(organics).
-48-
-------
In October 1982, the VOC's listed below were detected in MW 7Bj
and MW
carbon tetrachloride benzene
1,2 dichloroethane toluene
1,1,2 trichloroethane chloroform
chloroform 1,2,2 trichloroethane
benzene trans-1,2 dichloroethane
In December 1982, both the Environmental Protection Agency (Region VI)
and the Louisiana Department of Environmental Quality requested Rollins (LA)
to achieve full compliance with the interim status ground-water monitoring
regulations (40 CFR 265, Subpart F) by submittal of a written facility ground-
water sampling and analysis plan, utilization of statistical t-tests when
applicable, and provide additional water quality criteria. These requests
were in conformance with the Louisiana Department of Environmental Quality
Hazardous Waste Management Permit Application. A ground-water sampling and
analysis plan was subsequently included in the Hazardous Waste Management
Permit Application. Although requested in 1982, Rollins (LA) did not submit
any statistical analyses until 1984.
1983
As a result of the presence of contaminants indicated in 1982 in the
ground water at the locations of MW 7Bj, MW 8Bj, and SMS, an additional
three (3) ground-water recovery wells (interceptor wells 1 3 through Ig),
were installed in March 1983 (reference Figure 6). Two (2) additional
ground-water monitoring wells, MW's 13A and 13Bj, were installed in March
-49-
-------
1983 also (reference Figure 5). Monitoring wells 13A and 13B^ are located
adjacent (east) of MW's 7A and 7B}. These two (2) monitoring wells also
indicated the presence of contaminants in the ground water.
Interceptor well 13 is located upgradient of MW 8Bj and is screened
sixty (60) to sixty-five (65) feet below land surface. Interceptor well 1^
is located upgradient of MW 76} and is screened seventy-five (75) to eighty-
five (85) feet below land surface. Interceptor well Ig is located upgradient
of MW's 13A and 13Bj, and SM3. This recovery well is screened at two (2)
depths, thirty-four (34) to thirty-nine (39) feet and fifty (50) to fifty-
five (55) feet below land surface. Interceptor wells 13, 1^ and 1^
remove contaminated ground water from the same formation beds that MW 8Bj,
MW 7B1} and MW's 13A and 136} are screened in, respectively. The ground
water recovered from these three (3) wells is analyzed for the presence of
VOC's. This is on a monthly schedule.
All the ground-water monitoring wells were analyzed under an alternate
ground-water monitoring plan on a quarterly schedule in 1983 and for the
first quarter of 1984 for the parameters listed on Table C. Ground water
collected at the location of MW 11A indicated the presence of total VOC's
at 0.112 mg/1 (August 1983 quarterly sampling event).
1984
Prior to August 1984, the Environmental Protection Agency (Region VI)
and the Louisiana Department of Environmental Quality again requested that
Rollins (LA) fully comply with the interim status regulations concerning
the ground-water monitoring program, such as: quarterly monitoring of the
ground water for the interim status parameters, obtain ground water levels
-50-
-------
on a quarterly schedule, conduct all sampling and analysis procedures in
accordance with an approved written sampling and analysis plan, including
sample collecting of replicates on the upgradient wells and establishing
statistical analyses. In response to this request, Rollins (LA) designated
MW's 1A, IB} and 1C as the hydraulically upgradient monitoring wells and
MW's 4A, 4Bj and 4C, 6A and 6Blt 7A and 76^ 8A and SBj, and MW 9C as
the hydraulically downgradient wells located at the limit of the waste man-
agement area. The limit of the waste management area was and is defined
by Rollins (LA) as the original Rollins (LA) site property line (excluding
the Allied north tract and the Western tract properties).
Rollins (LA) initially submitted an annual ground-water monitoring
report in August 1984, and subsequently in 1985. These reports provided an
assessment of the presence of contaminants indicated in the ground water.
In June 1984, Rollins (LA) provided statistical analyses for the ground-water
monitoring wells. Rollins (LA) compared the four (4) quarters of the 1983
analytical data to the first quarter 1984 analytical data for PH, specific -
conductance, and total organic carbon (TOC). Although the analyses indicated "
significant variations for several parameters, Rollins (LA) stated that the
results were inconclusive due to an incomplete data base for the upgradient
monitoring wells, and the lack of collection of replicate samples. Previously,
collection of ground-water samples for replicate analyses did not commence
until first quarter of 1985. This included ground water collected from the
upgradient monitoring wells and from the downgradient monitoring well cluster
4A, 4Bj and 4C. Rollins (LA) had not submitted statistical analyses for
the groundwater monitoring system because assessment ground-water monitoring
had already been initiated. Site specific ground-water contamination indicators
were utilized in lieu of the RCRA interim status indicator parameters.
-51-
-------
Ground-water monitoring wells 14A, 148} and 14C were installed in May
1984. These wells were installed to obtain additional background ground-
water quality information (reference Figure 5).
In July 1984, MW's 15A and 15Bj were installed downgradient of the new
kiln dust "mix" building which accommodates treatment of specific hazardous
wastes. These wells were installed as requested by the Louisiana Department
of Environmental Quality. The new "mixing" facility did not commence operation
until June 30, 1985 (reference Figure 5).
On October 12, 1984, the Environmental Protection Agency (Region VI)
issued Rollins (LA) an Administrative Order; Docket Number RCRA-3013-08-84
pursuant to the authority of Section 3013 of RCRA. The order required further
ground-water monitoring, sampling, analyses and reporting, due to, specifi-
cally; inadequate site characterization, inadequate assessment of the rate
and extent of the contaminant plumes, and failure to address the presence
of contaminants indicated in the ground water at MW 11A.
Concurrent with the October 12, 1984, order, the Environmental Protection
Agency (Region VI) issued Rollins (LA) a Compliance Order and Notice of
Opportunity for Hearing on November 20, 1984. This order was issued pursuant
to the authority of Section 3008 of RCRA and addressed areas of noncompliance
regarding required notifications, facility operations, and ground-water
monitoring assessment. Subsequently, on June 14, 1985, the Environmental
Protection Agency (Region VI) issued a Consent Agreement and Final Order
to Rollins (LA) for the above-mentioned October 19, 1984, order.

1985
To comply with the requirements of the 3013 and 3008 orders concerning
ground-water monitoring and assessment, Rollins (LA) conducted a hydrogeo-
logic study in April 1985. Just prior to the study, Rollins (LA) purchased
the Allied Corporation north tract (approximately seventy-one (71) acres)
on February 20, 1985, and acquired monitoring wells SM2, SMS, SM4, SMS, and
DM3. Nine (9) borings, of which several were up to one hundred fifty (150)
feet in depth were augered. Six (6) of these borings were completed as
groundwater monitoring wells; 482, 58^ 16A, 178^ and 17Bo, and 20A
(reference Figure 5). These new monitoring wells and a select group of
existing monitoring wells were utilized to assess the status of the ground
water at the Rollins (LA) site with respect to the presence of contaminants.
The Environmental Protection Agency determined that Rollins (LA) had satis-
factorily complied with the requirements of the order. The requirements of
the order were deemed completed on May 2, 1985.
The ground-water monitoring wells installed as a result of the 3013 Order
were sampled in July 1985. Ground water from these wells were analyzed for
the presence of VOC's. The presence of contaminants to the ground water was
not indicated in any of these monitoring wells with the exception of MW 5Bj.
Ground-water monitoring well 9C was plugged and abandoned in February
1986 due to construction of the new landfill cell 901. Prior to abandonment,
a new monitoring well, 9Cr, was installed in November 1985 approximately one
hundred (100) feet west of MW 9C and was completed in the same permeable bed
within the C zone (reference Figure 5).

1986
Currently, the Rollins (LA) facility is continuing assessment ground-
water monitoring as required by LA Chapter 23, Subchapter V. The two (2)
columns in Table D list the present assessment ground-water monitoring wells
and the two (2) columns in Table E list the parameters for analyses in the
assessment program. The headings of the two (2) columns (RCRA Detection
Ground-water Monitoring System and Detection Ground-Water Monitoring System)
were designations made by Rollins (LA) and are strictly a company internal
classifaction scheme; these classifications are not used by the Task Force.
Furthermore, as a part of the assessment ground-water monitoring program,
Rollins (LA) analyzes the ground water collected at the locations of monitor-
ing wells 4A, 4Bl5 76}, 8B}, 10A, 11A, I2A, and ISA and the interceptor
(ground-water recovery) wells, I through I5, for the presence of VOC's on
a monthly basis (reference Table F).
A southern limit (Rollins (LA)/Allied north tract property line) and
western limit (Rollins (LA)/Western tract property line) of the site waste
management area border the downgradient sides of an area that includes land-
fills 717/901 and the inactive pre-RCRA cells 611B, 619, and 719. Another
more southern limit (Rollins (LA)/Allied property line) and western limit
(Rollins (LA)/Allied north tract eastern property line) of the site waste
management area border the downgradient sides of an area that includes; the
inactive pre-RCRA Hy Purle landfill (capped), the active RCRA hazardous waste
surface impoundment equalization basin 302, and another inactive pre-RCRA
landfill (capped) south of the equalization basin. Reference Figure 3.
-54-
-------
For ease of discussi'on regarding the location of the monitoring wells,
the Task Force document references the site waste management area to include
a landfill 717/901 waste management area, and equalization basin 302/inactive
Hy Purle and inactive south landfills waste management area. (Reference to
these waste management areas are for descriptive purposes and are not recog-
nized by the Louisiana Department of Environmental Quality or Rollins (LA)).
Ground-water monitoring wells located on the northern, eastern, and southern
limits of the site waste management area are discussed also.
The Rollins (LA) site upgradient assessment ground-water monitoring wells
are presently MW's 1A, IBj and 1C, 2A, 11A, llBj and 11C, 14A, lABj and
14C, and ISA (reference Figure 5).
Downgradient ground-water monitoring wells 6A and 6Bj, 7A and 7Bi, 12A,
13A and 13B}, and 8A and 8Bj are located at the southern limit of the land-
fill 717/901 waste management area. Downgradient monitoring wells 8A and 8Bj,
and 9Cr are located at the western limit of the landfill 717/901 waste manage-
ment area (reference Figures 3 and 5).
Adjacent (east) to landfill 717/901 are several active RCRA regulated
hazardous waste impoundments; the scrubber basin (asphalt lined), the north
stabilization basin (clay lined), the truck wash basin (clay lined) and the
activated sludge basin I (asphalt lined), (reference Figure 3). These sur-
face impoundments are considered, by the Task Force, to be associated with
the landfill 717/901 waste management area.
The equalization basin 302/inactive Hy Purle and inactive south landfills
waste management area consists of the inactive pre-RCRA Hy Purle landfill
-55-
-------
(capped), the active RCRA hazardous waste surface impoundment equalization
basin 302, and another inactive pre-RCRA landfill (capped) south of the
equalization basin 302 (reference Figures 3 and 6).
Ground-water monitoring wells 4A, 48} and 4C are located at the inter-
section of the southern and western limit, and monitoring wells 5A and 58}
are located at the western limit of the above-mentioned waste management
area. Monitoring well 482 is located beyond the western limit southwest
of MW's 4A, 48} and 4C (reference Figure 3).
Ground-water monitoring wells 10A and 108,, 11A, 118} and 11C, 14A,
148} and 14C, and 16A are located at the northern limit, MW's 1A, 18} and
1C, and 2A are located at the eastern limit, and MW 3A is located at the
southern limit of the site.waste management area (reference Figure 5).

Assessment Ground-Hater Monitoring System*
As a result of the evaluation of the assessment ground-water monitor-
ing system, the Hazardous Waste Ground-Water Task Force has determined that
further assessment of the rate and extent of the hazardous constituents
present in the ground water is required. A discussion of the assessment
ground-water monitoring system follows:
A. Active Landfill 717/901 Waste Management Area
The landfill is situated such that ground-water flow traverses
both the southern and western limits of the waste management area
in the downgradient direction. Ground-water wells 6A and 6Bj, 7A
and 7B^, 8A and SBj, 12A, and 13A and 13Bj monitor the southern
limit. Monitoring wells 8A and 8Bj are located at the intersection
of the southern and western limits of the waste management area,
therefore, are considered to monitor both boundaries. Monitoring
well 9Cr, 10A and lOBj also monitor the western limit. Monitoring-
wells 17B1 and 17B2, 20A, and SMS are located on the Allied north
tract south of the Rollins (LA)/Allied north tract boundary.
Monitoring wells 15A and ISBj, are located on the the Western
tract approximately five hundred (500) feet southwest of monitor-
ing wells 8A and 8Bj.

-------
a. MW's 6A and 6B^ - This ground-water monitoring well cluster
was installed in December 1980 and is located in the south-
east corner of the southern limit of the landfill 717/901
waste management area. Monitoring well 6A is screened for
five (5) feet approximately midsection of an A zone clay
bed. Silt and/or sand beds are not present in the A zone
at this location. Monitoring well 6Bj is screened in the
lower four (4) feet of a Bj zone clay bed (this is the
continuation of the A zone clay bed across an arbitrary
A/B! zone boundary) and into one (1) foot of a five (5)
foot B1 zone sand bed. A 82 zone sand bed (four (4) feet
thick) and a C zone sand bed (upper fifteen (15) feet
penetrated) are present at the location of the MW 6 well
cluster. However, the B£ and C zone sand beds are current-
ly not monitored for the presence of contaminants in the
ground water at this location.
Contaminants (organics) were initially detected in late
1981.2 In 1984, the presence of an inorganic (lead) was
detected in the ground water at the location of MW 6A. Also
in 1984, the presence of several organics were detected in
the ground water at the location of MW 6Bj, however, the
concentration of these organics were reported below the
n
•The Task Force reviewed the Rollins (LA) site ground-water analytical
results for 1983 through the third quarter of 1986 (if available), as
well as, the results of the Task Force ground-water sampling effort in
November 1986. In reference to this document, the presence of contaminants
is limited to the reference of organics (volatile, semi-volatile, and
pesticides (PCB'S) in a concentration above the contract laboratory detection
limit and/or inorganics (metals only) in a concentration above the interim
primary drinking water standards, unless otherwise noted.
-58-
-------
contract laboratory detection limits. Analytical data for
1985 indicated the detection of an inorganic (lead) in MW's
6A and 6Bj. The presence of organics were also detected
in MW 6A. The Task Force analytical data has indicated
the detection of contaminants (organics) in MW's 6A and
6B^. However, only one of these organic constituents
was detected (in MW 6B^) at a concentration above the
contract laboratory detection limit.
Contaminants are present in the ground water at the
location of monitoring wells 6A and 6Bj (initially detected
in late 1981). An assessment of the extent of the contami-
nants at the specific location of the MW 6 cluster was not
included in the October 1984, §3013 Environmental Protection
Agency administrative order issued to Rollins (LA). The
downgradient monitoring wells in close proximity to the MW 6
well cluster are SMS (formerly an Allied monitoring well)
and MW 20A. Monitoring well SMS is located approximately
four hundred fifteen (415) feet southwest of MW's 6A and
6Bj. Monitoring well 20A is located approximately five
hundred sixty-five (565) feet directly south of moni-
toring well SMS. Contaminants have been detected in the
ground water at the locations of SMS (initially detected
June 1982) and MW 20A (initially detected in spring 1985).
It cannot be determined if the immediate area in the vicin-
ity of MW 6A was the source of the dispersion of contamin-
ants detected in these two monitoring wells. All the
-59-
-------
ground-water monitoring wells located at the southern limit
presently, or have previously, detected the presence of con-
taminants in the ground water.
Monitoring well SMS is screened for five (5) feet in
the upper portion of a twelve (12) foot A zone sand bed.
Monitoring well 20A is screened in the lower nine (9) feet
of an eighteen (18) foot Bj zone clay bed. The designated
A and Bj zones in the locale of SMS, 20A, and MW's ISA and
ISBi (located approximately two hundred (200) feet north
of SMS) exhibit a thickening trend in the A/B^ zone silts
and sands. A more permeable bed (silt and/or sand) which
is observed at the above-mentioned monitoring wells is not
present at the location of MW 6A. The silt and sand beds
present at the location of MW 6Bj are structurally situated
lower in elevation (above msl) that the A/B^ zone silt and
sand beds present at the location of SMS, MW 20A, and MW's'
ISA and ISBj. It is probable that the A/Bj zone silts
and sands observed at SMS, MW 20A, and MW's ISA and ISBj
are isolated from the Bj zone silt and sand beds present
at the location of MW 6Bj.
The extent of the contaminants detected in the A zone
clay bed at the location of MW 6A remains undetermined east
of SMS and south of MW's 6A and SB-^. The extent of the
contaminants detected in the BI zone clay and sand bed at
the location of MW 6Bj has not been assessed by Rollins
(LA). Contaminants have been detected in the B^ zone at
-60-
-------
neighboring monitoring well 13B^ (detected in a B^ zone
sand bed), located approximately four hundred eighty (480)
feet west of MW 6B^. Contaminants have also been detected
in MW 7B^ (detected in a Bg zone clay and silt bed)
located approximately five hundred eighty (580) feet west
of MW 6Bj. Monitoring well 5Bj, which is located eight
hundred seventy (870) feet south of MW 6Bj, has detected
the presence of contaminants. Monitoring well 5Bi appears
to monitor the same sand and silt beds present at the loca-
tion of MW 6Bj.
b. MU's 7A and 76^ - This ground-water monitoring well cluster
was installed in December 1980 and is located approximately
nidsection (approximately five hundred eighty (580) feet
east of the MW 6 well cluster) of the landfill 717/901 waste
management area. Monitoring well 7A is screened approximately
midsection of an A zone clay bed which extends through an arbi-
trary A/BI zone boundary into the Bi zone. The monitoring
well designated 7Bj is actually screened for three (3) feet
in a B£ zone clay bed and into the upper two (2) feet of a
B2 zone silt bed. A Bj zone silt bed (six (6) feet thick)
and sand bed (nine (9) feet thick), and a C zone sand bed that
are present at the MW 7 well cluster are currently not monitored
for the presence of contaminants in the ground water.
The presence of contaminants have been detected in the
ground water at the location of MW's 7A and 7Bj. Contami-
nants (organics) were initially detected in MW 7Bj in October
-61-
-------
1982, and subsequently in MW 7A. Analytical data for 1983
indicated the detection of contaminants (organics) in the
ground water at the location of MW 7B}. In 1984, the pre-
sence of contaminants (organics) were again detected in both
MW's 7A and 76}. Also, an inorganic (lead) was detected
in the ground water at the location of MW 7Bj. Ground-water
monitoring wells 7A and 78} were not selected for sampling
for the Task Force evaluation.
The October 12, 1984, Environmental Protection Agency
§3013 administrative order required Rollins (LA) to install
assessment ground-water monitoring wells to determine the
extent of the contaminants present in the ground water at
the southern limit of the landfill waste management area.
As a result, three assessment ground-water monitoring wells
(MW's 17B} and 17B2, and MW 20A) were installed south of
the southern limit of the waste management area. Monitoring
well 20A was installed to assess the presence of contaminants
detected in the area of MW's 13A and 138}, and SMS. The
MW 7 well cluster is located west of MW's ISA and 138}, and
northwest of MW 20A and SMS.
The extent of the contaminants detected at the location
of MW 78} remain unknown as there are no monitoring wells
downgradient of MW 78} that are screened in the B2 zone.
Monitoring well 1782 is screened in the &2 zone» however,
this monitoring well is located approximately one thousand
(1,000) feet west/southwest of the MW 7 well cluster and
is directly south of the MW 8 well cluster. It is assumed
-62-
-------
by the Task Force that the Bj zone at the MW 7 well clus-
ter would also detect the presence of contaminants . The
presence of contaminants have also been detected in the
B} zone at the locations of the adjacent monitoring wells
6Bj and 13Bj (east), and 8Bj (west). Should contamin-
nants be present in the Bj zone at the location of the MW 7
well cluster, no suitable ground-water monitoring wells
are situated to the south/southwest which could be utilized to
aid in determining the extent of the contaminants. Moni-
toring well 17B} is located west/southwest of the MW 7
well cluster, however, at approximately one thousand (1,000)
feet in distance.
c. MW's 8A and 8B^ - This ground-water monitoring well cluster
was installed in December 1980 and is located in the south-
west corner of the southern limit of the landfill 717/901
waste management area (approximately nine hundred twenty
(920) feet west of the MW 7 well cluster). Monitoring
well 8A is screened in five (5) feet of the A zone clay
bed approximately one (1) foot above a three (3) foot A
zone silt bed. Monitoring well SBj is screened in five
(5) feet of a Bj zone clay bed approximately several
feet above a four (4) foot Bj zone sand bed. An A zone
silt bed and a B^ zone silt and sand bed are present at
the location of the MW 8 well cluster, as well as, a B£
zone sand bed (three (3) feet thick) and a silt bed (five
(5) feet thick). These permeable beds in the A, Bj and
B£ zones are currently not monitored for the presence of
contaminants in the ground water. It has not been deter-
-63-
-------
mined if a C zone sand bed exists at this location.
The presence of contaminants (organics) were initially
detected in 1982 at the location of MW 8Blf and subsequently
at MW 8A. The presence of contaminants (organics) were
again detected in the ground water at the location of MW
8Bj in 1983. Analytical data for both 1984 and 1985 indicated
the detection of contaminants (organics) in the ground
water at the locations of MW's 8A and 8B}. Inorganics
were also detected at the location of MW's 8A (1984; chromium,
and 1985; arsenic, cadmium, and lead) and SBj (1984;
arsenic and lead, and 1985; arsenic cadmium, and lead).
Analytical data resultant of the Task Force evaluation has
indicated the detection of contaminants (organics) in the
ground water at the location of MW's 8A and 8Bj. However,
the concentrations are reported below the contract laboratory
detection limits.
As required by the October 12, 1984, Environmental
Protection Agency §3013 administrative order, Rollins
installed an assessment ground-water monitoring well cluster
UBj and 17B2 adjacent (south) of MW's 8A and 8B1. This
assessment monitoring well cluster does not have a monitor-
ing well completed in the A zone. The monitoring well 15
well cluster monitors the A zone silt bed at .the,location
of MW ISA. However, MW 15A is approximately five hundred
(500) feet southwest of MW 8A and is downgradient of the
kiln dust "mix" building. The MW 15 well cluster was
-64-
-------
installed to monitor the ground water for a release of con-
taminants in the locale of the kiln dust "mix" building.
Monitoring well 178} is screened in what appears to be
the same Bj zone sand bed in which that MW SBj is screened.
Monitoring well 17Bj has previously indicated theIJreTefice "-
of contaminants (organics). Monitoring well 156^ is screened
in a B^ zone silt bed which is below the sand bed (this silt
and sand bed is separated by a clay bed) that is present at
the MW 8, MW 17, and MW 15 well clusters. The A zone perm-
eable bed remains unassessed at the locations of the MW 8
and MW 17 well clusters. The 62 zone sand bed present at
the location of MW 8Bj is being adequately assessed by MW
17B}. The extent of contaminants beyond MW 8Bj has not
been assessed in the A, B and C (if present) zones to the
west and immediate southwest, due to the unavailability of
monitoring wells for data generation.
d. MW 12A - This ground-water monitoring well was installed
in February 1983 and is located at the southern limit of
the landfill 717/901 wast management areas adjacent (east)
to MW's 13A and 138}. Monitoring well 12A is completed
to the base of the A zone and is screened in the lower
five (5) feet of an eight (8) foot silt bed.
Contaminants (organics) were initially detected in
1983, and subsequently in 1984. The analytical results for
1985 and 1986 were not reviewed. Ground-water monitoring
well 12A was not selected for sampling during the Task Force
evaluation.
-65-
-------
The A zone silt bed present at the location of MW 12A
is not observed at MW 7A which is located adjacent (west),
or MW 6A which is located to the east. To the south, this
A zone silt bed is equivalent in depth to a sand bed which
is monitored at SMS (the presence of contaminants have""^
been detected). It has not been determined if there is
continuity of these permeable beds between the two monitoring
wells, 12A and SMS, or. probable isolation. This A zone silt
bed is again observed in MW 20A. However, only the Bj
zone permeable bed is monitored. The presence of contaminants
have been detected in the A zone in the ground-water monitor-
ing wells located east, west, and south of MW 12A.
e. MW's ISA and 13B| - This ground-water monitoring well
cluster was installed in March 1983 and is located
approximately midsection ( east of MW's 7A and 7Bj) of the
southern limit of the landfill 717/901 waste management
area. Monitoring well ISA is screened for five (5) feet
midsection of a twelve (12) foot A zone silt bed. Monitor-
ing well ISBj is screened in the lower five (5) feet of a
six (6) foot B} zone sand bed.
At the time of the ground-water monitoring well install-
ation, a chemical odor was detected in the A zone from
thirty-six (36) to thirty-eight (38) feet and in the Bj
zone from fifty-four (54) to fifty-six (56) feet. The
presence of contaminants (organics) were initially detected
in both MW's ISA and 13B1 in 1983. Subsequently, contamin-
ants (organics) were detected in both MW's ISA and
-66-
-------
in 1984,' 1985, and 1986. Also, analytical data resultant
of the Task Force evaluation has indicated the detection
of contaminants (organics) in the ground water at the loca-
tion of MW's ISA and ISBj. The presence of contaminants
have also been detected in the A and B zones in MW 12A,
MW's 7A and 76^ SM3, and MW 20A which are located east,
west, and south of MW's ISA and ISBj, respectively.
The A zone silt bed is present at the locations of
the adjacent MW's 12A (east) and 20A (south). An A zone
sand bed, rather than the silt bed, is observed at SMS.
This silt bed is not observed at the locations of MW's 6A
or 7A. An A zone silt bed is observed in MW 8A, however,
does not appear to be associated with the MW ISA silt bed.
The Bj zone sand bed is present at the locations of MW 7,
SMS, and MW 20A. The adjacent monitoring well cluster to
the west, MW 7, has detected the presence of contaminants
in a B2 zone silt bed. The status of the B2 zone at the
location of the MW 13 well cluster has not been determined.
The status of a C zone, if present, has not been determined,
either.
2. Downgradient Ground-Water Monitoring Wells South of the Southern
Limit; MW's 17Bj and 17B2,.MW 20A, and SMS
a. MW's 17B1 and 17B? - This ground-water monitoring well
cluster was installed in April 1985 and is located in the
northwest corner of the Allied north tract south of the
southern limit of the landfill 717/901 waste management
-67-
-------
area. These wells are approximately two hundred (200) feet
directly south of MW's 8A and 8Bj. Monitoring well 17Bj
is screened in the lower three (3) feet of a thirteen (13)
foot BI zone clay bed, through one (1) foot of a B, zone
sand bed, and into the upper foot of a five (5) foot Bj
zone clay bed. Monitoring well 17B2 is screened in the
lower two (2) feet of a B^ zone clay bed, through one (1)
foot of a B£ zone sand bed, and into a two (2) foot B2
zone silt bed.
Contaminants (organics) were sporadically detected in
MW 178} in 1985 and 1986. To date, the presence of cont-
aminants have not been detected in MW 17B2.
As previously mentioned, MW's 17Bj and 17B2 were
installed to assess the extent of the presence of contami-
nants in the vicinity of MW's 8A and SBj. The MW 17 well
cluster does not include monitoring the permeable beds (silt)
present in the A zone in this area. The current status of
the A zone at this location remains unknown. The Bj zone
sand is present in the area of the MW 8 and MW 15 well clus-
ters, however, is not monitored at these two (2) locations.
Monitoring well 17B2 is the only location other than
the MW 7B well cluster (which has detected the presence of
v
contaminants) where the B2 zone is monitored at the southern
limit of and beyond the waste management area.
-68-
-------
b. MW 20A - This ground-water monitoring well was installed in
April 1985 and is located on the Allied north tract, south
of the southern limit of the landfill 717/901 waste manage-
ment area. Monitoring well 20A is approximately two hundred
fifty (250) feet south of SMS, which is approximately two
hundred fifty (250) feet south of MW's 13A and ISBj. The
well is actually screened in the lower nine (9) feet of an
eighteen (18) foot B^ zone sand bed into one (1) foot of
Bj zone clay bed.
A chemical odor was noticed in the Bj zone from
forty-two (42) to fifty-three (53) feet at the time of
installation. The sporadic presence of contaminants
(organics) were initially detected in 1985. Analytical
data resultant of the Task Force evaluation has indicated
the presence of contaminants (organics), however, at
concentrations below the the contract laboratory detection
limits.
The A/BI zone silt and sand bed is not monitored for
the presence of contaminants in the A zone at the location
of MW 20A. Contaminants have been detected in the A zone
bed at the locations of MW's ISA and SMS. The B± zone sand
bed screened at the location of MW 20A is also observed at
the locations of MW's ISBj and SM3. The presence of con-
taminants (organics) have been detected in MW ISBj. The
status of a B2 and C zone at the location of MW 20A has
not been determined.

-------
c. SMS - This ground-water monitoring well was installed in
1982 and is located on the Allied north tract south of the
approximate midsection of the southern limit of the landfill
717/901 waste management area. This monitoring well is
directly south of MW's ISA and ISBj. Monitoring well SMS
is screened for five (5) feet in a twelve (12) foot A zone
sand bed two (2) feet below the top of this bed.
The presence of contaminants (organics) were initially
detected in SMS in 1982. Subsequently, the presence of con-
taminants (organics) had been detected until 1985. After a
period indicating the absence of these contaminants, the pre-
sence of contaminants (organics) were again detected in 1986.
It appears that in this location the A zone sand bed merges
with a Bj zone silt bed. This A zone sand bed is not present
at the locations of the MW 6 and MW 7 well clusters, and is
equivalent to a silt bed in MW 12A, MW's ISA and ISBj, and
MW 20A. A Bj zone sand bed does merge with the A zone silt
bed at these monitoring well locations. It has not been
determined if there is continuity of this A zone sand bed
with the silt beds observed at an equivalent depth in MW
12A, MW's ISA and ISBj, and MW 20A. The extent of the
contaminants present in the A zone at this location has
not been determined. A B2 zone sand bed is present at
this location, however, is not monitored. The status of
this B2 zone sand bed and a C zone (if present) has not
been determined, either.

d. Western Limit Downgradient Monitoring Wells 8A and 8B}, and
MW 9Cr
1. MW's 8A and 8Bj - Reference the discussion under l.b.3.
of this section.
2. MW 9Cr - This ground-water monitoring well was installed
in January 1986 and is located approximately one hundred
(100) feet west of the original MW 9C. Monitoring well
9Cr replaced MW 9C to allow for landfill expansion to
the west, and is located approximately midsection (approx-
imately eight hundred fifty (850) feet north of MW's
8A and 8B}) of the western limit of the landfill 717/901
waste management area. Monitoring well 9Cr is screened
for ten (10) feet one (1) foot above the bottom of a
twenty-two (22) foot C zone sand bed. Permeable beds
are present within the A, Bj and B2 zone clay beds at
the location of MW 9C. Only ninety (90) to one hundred
forty (140) feet were cored for a geologic description
of the formation beds at the location of MW 9Cr. The
geologic description of the first ninety (90) feet
feet is referenced from MW 9C. An A zone silt bed, a
Bj sand bed, and a B2 zone silt bed are present at
the location of MW 9C. The A, Bj and B2 zones are
not monitored for the detection of a release of contami-
nants to the ground water at the location of MW 9Cr.
-71-
-------
The original MW 9C indicated the detection of the
presence of contaminants (organics) in the ground water
at this location in November 1981. Subsequent sampling
in the same month indicated the detection of a significant
decrease in the concentration of the organic contaminants.
In 1984 and 1985, the analytical data again indicated
the detection of the sporadic presence of contaminants
(organics) in MW 9G. The analyses resultant of the Task
Force evaluation did not indicate the detection of con-
taminants at the location of MW 9Cr.
Monitoring well 9Cr is located approximately mid-
section along the western limit of the waste management
area between the MW 10 well cluster (located at the
northwest corner of the waste management area) and the
MW 8 well cluster (located at the southwest corner of
the waste management area). Both the MW 10 and MW 8
well clusters have detected the presence of contaminants
at these locations. The A, B^ and B2 zones at the
location of MW 9Cr have not been assessed regarding the
the presence of contaminants of which have been indi-
cated in the ground water in the A and Bj zones north
and south of MW 9Cr.
-------
1. MW's ISA and 15B-. - This ground-water monitoring well
cluster was installed in July 1984 and is located on
the western tract approximately five hundred (500) feet
southwest of MW's 8A and 8Bj. Ground-water monitoring
wells 15A and 15Bj are immediately downgradient of the
kiln dust "mix" building. Monitoring well 15A is screened
in the lower three (3) feet of an A zone clay bed into
the upper two (2) feet of an A zone silt bed. Monitoring
well 15Bi is screened in the last foot of a Bj zone clay
bed into the upper four (4) feet of a six (6) foot Bj
zone silt bed.
The presence of contaminants (inorganics) were
initially detected in MW's 15A and 15B1 (lead) in late
1984. The presence of an organic was also detected
in MW ISBj. Subsequently, only MW IBBj has sporadi-
cally detected the presence of contaminants (organics)
in 1985 and 1986.
Monitoring well 15A is screened in the same A
zone silt bed as MW 8A. It cannot be determined if
this silt bed is continuous with the A zone silt beds
present at the other monitoring well locations along
the southern and the western limits of the landfill
717/901 waste management area. There are two permeable
zones (isolated by a clay bed) within the Bj zone at
this monitoring well location, a silt and sand bed
that are approximately eight (8) feet thick combined.
-73-
-------
At a greater depth is the six (6) foot silt bed that
is currently being monitored. The disposition of the
silt and sand bed concerning the presence of contaminants
has not been determined since only the silt bed below
these beds is subject to ground-water monitoring. A
8 £ zone silt bed is also present at this location, but is
not subject to ground-water monitoring. There does
not appear to be a sand bed within the C zone at this
location, only thin intermittent silt beds. It would
be difficult to determine the source of contamination
at this location because contamination is present in
the vicinity of the MW 8 well cluster which is approxi-
mately five hundred (500) feet upgradient of the MW 15
well cluster. Many of the same hazardous constituants
are characteristic to both the landfill and the kiln
dust "mix" building activities.
B. The Equalization Basin 302/Inactive Hy Purle and Inactive South
Landfills Waste Management Area Downgradient Ground-Water Monitoring
Wells
. .->i.
The equalization basin 302 is situated such that ground-water
«•"
flow traverses both the southern and western limits of th* waste
management area in the downgradient direction. This situation is
• _ —s
also the same regarding the inactive Hy Purle landfill north of
equalization basin 302 and the inactive landfill located directly
south of equalization basin 302. Ground-water monitoring wells
5A and 5Bj are located at the western limit.
-74-
-------
Monitoring wells 4A, 4Bj and 4C are located at the inter-
section of the southern and western limits of the waste management
area, therefore, are considered to monitor both boundaries. Ground-
water monitoring well 4B£ is located beyond the western limit of
the waste management area, approximately two hundred twenty-five
(225) feet southwest of the MW 4 well cluster.
1. Southern and Western Limit Downgradient Ground-Water Monitoring
Wells 4A, 4B1§ and 4C, and 5A and 5B1
a. MW's 4A, 4B^ and 4C - This ground water monitoring well cluster
was installed in December 1980, and is located in the south-
west corner of the equalization basin 302/Inactive Hy Purle
and Inactive South Landfills waste management area approximately
eight hundred twenty-five (825) feet southwest of the equal-
ization basin 302. Monitoring well 4A is screened in the
lower three (3) feet of a five (5) foot A zone silt bed
and into the upper two (2) feet of a nine (9) foot A/Bj
zone sand bed. Monitoring well 4B} is actually screened
in the lower five (5) feet of a six (6) foot B£ zone sand
bed. Monitoring well 4C is screened in reference to an
adjacent soil boring (GM-3) located on the Allied north
tract. Therefore, placement of the well screen in the C
zone sand bed is an estimation. A geologic description of
the sediments encountered at the location of the MW 4 well
cluster is recorded to eighty-five (85) feet. The 4C zone
monitoring well is screened in a sand bed for ten (10)
feet, from one hundred fifteen (115) to one hundred twenty-five
-75-
-------
(125) feet. A record of the geologic description from
eighty-five (85) feet to one hundred twenty-five (125)
feet at the location of the MW 4 well cluster is not available,
The presence of contaminants (organics and Inorganics)
were initially detected in MW's 4A and 4!^ in 1981. Subse-
quent ground-water sampling in 1983, 1984, and 1985 indicated
the detection of contaminants (organics) in MW's 4A and 4Bj.
Inorganics were also detected in MW's 4A (1984; chromium)
and 4Bi (1984; lead). The presence of a contaminant (organic)
was indicated in MW 4C in 1984, however, the concentration
was below the laboratory detection limit. The presence of
contaminants (organics) were again detected in MW 4C in
1985. Ground-water samples were collected only at MW 4C
during the Task Force evaluation. The Task Force analytical
data for MW 4C did not indicate the presence of contaminants.
The extent of the contaminants present in the A/B^ zone
at the location of the MW 4 well cluster remains unassessed.
Several ground-water monitoring wells are adjacent (south)
of the MW 4 cluster. Monitoring wells SMI and DM2 are
screened in the A and Bj zones, respectively. However,
these monitoring wells service the Allied Corporation and
are not associated with the Rollins (LA) ground-water
monitoring system. The extent of the contaminants detectd
in the B£ zone have not been assessed to the south. The
status of the C zone in the area of the MW 4 well cluster
has not been determined, either.
-76-
-------
b. MW's 5A and 58^ - Monitoring well 5A was installed in
December 1980 and MW 5Bj was installed in April 1985.
Monitoring well 58} was installed as an assessment well
resultant of the Environmental Protection Agency §3013
administrative order. Both monitoring wells are located
approximately midsection of the western limit of the waste
management area, two hundred forty (240) feet west of
equalization basin 302. Monitoring well 5A is actually
screened for five (5) feet in a B^ zone clay bed. Moni-
toring well 58} is screened in the lower three (3) feet of
a B! zone clay bed and into the upper two (2) feet of a
three (3) foot Bj zone sand bed.
The presence of a contaminant (inorganic; lead) was
detected in MW 5A in 1985. The presence of a contaminant
(organic) was also detected in MW 5Bj in 1985. Monitoring
wells 5A and 5Bj were not selected for sampling for the
Task Force evaluation.
The 8^ zone clay bed that is screened in MW 5A is an
extension of the A zone clay bed across an arbitrary A/Bi
zone boundary. The 5Bi monitoring well is screened in the
lower three (3) feet of the same Bj zone clay bed continuing
into the upper two (2) feet of a three (3) foot Bj zone
sand bed. This Bj zone sand bed is partially screened at
MW 4A which is located at the southwest corner of the waste
management area. At this location an A zone silt bed merges
-77-
-------
with the BI zone sand bed. Contaminants have been detected
and are present in the ground water at this MW 4A location.
There are no ground-water monitoring wells that are completed
in the B^ zone permeable bed adjacent to or in proximity
to MW BBj, therefore, the extent of the contaminants in
the ground water at this locale cannot be determined. A
B2 zone sand bed and a C zone sand bed (if present) are
not monitored at the location of MW's 5A and 5Bi. It
remains unknown if contaminants are present in the ground
water in the two (2) above-mentioned zones.
2. Downgradient Ground-Water Monitoring Well West of the Western
Limit; MW 4B2
Ground-water monitoring well 4B2 was installed in April
1985 and is located approximately two hundred twenty-five
(225) feet southwest of the MW 4 well cluster. Ground-water
monitoring well 4B2 was installed resultant of the Environmental
Protection Agency §3013 administrative order to assess the
presence of contaminants detected at the MW 4 well cluster.
Only the B2 zone was screened and assessed. Monitoring well
4B2 is screened in the lower five (5) feet of a Bi/B? zone
clay bed into the upper foot of a B£ zone sand bed.
The presence of contaminants has not been detected in
MW 4B2. Monitoring well 4B2 is screened into the upper
foot of the same B2 zone sand bed in which MW 4Bj is
screened. However, the top of the MW 4Bj screen and the
base of the MW 4B2 well screen are completed at an
-78-
-------
equivalent depth. Due to the depth at which the MW 4B2 well screen was
set, this monitoring well may not be sufficient -to fully assess the
presence of contaminants in the Bo zone sand bed.
C. The Rollins (LA) Site Northern, Eastern, and Southern Property Lines
(Limits) for the Waste Management Area
Ground-water monitoring wells 10A and 10B^, 11A, 11B^ and
11C, 16A, and 14A, 14Bj and 14C are located on the northern
property line of the Rollins (LA) site. Monitoring wells 11A,
11B1 and 11C, 16A, and 14A, 14Bj and 14C are designated as upgradient
monitoring wells. Upgradient ground-water monitoring wells 1A,
IBi and 1C, and 2A are located on the eastern property line of the
site. Monitoring well 3A is located on the southern property line
of the site.
1. Northern Limit Ground-Water Monitoring Wells; 10A and 10B^,
11A, llBj and 11C, 16A, and 14A, 14Bj and 14C
a. Upgradient Ground-Water Monitoring Wells; 11A, HBj and
11C, 16A, and 14A, 14B1 and 14C
1. MW's 11A, UBi and 11C - This ground-water monitoring
well cluster was installed in December 1980 and is located
adjacent (north) to the northeast corner of the landfill
717/901 waste management area. Monitoring well 11A is
screened in the lower foot of a two (2) foot A zone
silt bed into the upper four (4) feet of an A zone
clay bed. Monitoring well llBj is screened in the
lower three (3) feet of an eight (8) foot B^ zone
silt bed into the upper (2) feet of an eighteen (18)
-79-
-------
foot Bj/Bg zone sand bed (this sand bed extends across
an arbitrary Bj^ zone boundary). Monitoring" well 11C
is screened one (1) foot in a C zone clay bed and into
five (5) feet of a C zone sand bed. The C zone well
screen is set at one hundred nineteen (119) feet to
one hundred twenty-nine (129) feet below land surface.
The boring B-17, which terminates at one hundred twenty-
five (125) feet, was referenced for the placement of
the MW's 11A, HBj and 11C well screens.
The presence of a contaminant (inorganic; cadmium)
was initially detected in MW 11C in 1981. Subsequently,
the presence of contaminants (organics) were not detected
until 1983 in MW 11A. Contaminants (organics) were also
detected in MW 11A in 1984. Analytical data resultant
of the Task Force evaluation detected the presence of
contaminants (organics) only in MW 11A.
The extent of the contaminants present at the location
of MW 11A have not been fully assessed. Ground-water
monitoring well 16A was installed upgradient of MW 11A
to assess the probable sources of the contaminants.
Monitoring well 16A has not indicated the presence of
contaminants in the A zone at this location. An assess-
ment monitoring well has not been installed downgradient
of the location of the MW 11 well cluster, therefore,
the extent of the contaminants detected in MW 11A
remains unknown.
-80-
-------
2. MW 16A - This ground-water monitoring well was installed
in April 1985 and is located in close proximity north-
east (upgradient) of the monitoring wells 11A, HB-\ and
11C. Monitoring well 16A was installed in response to
the October 1984 Environmental Protection Agency §3013
administrative order. This monitoring well is screened
in five (5) feet of an A zone clay bed at the approxi-
mate depth that the MW 11A well screen was placed.
Monitoring well 16A was utilized to assess the contam-
inants present at the location of MW 11A. The presence
of contaminants have not been detected at the location
of MW 16A.
3. MW's 14A, 148} and 14C - This ground-water monitoring
well cluster was installed in May 1984 and is located
in the northeast corner of the Rollins (LA) site property
lines. Monitoring well 14A is screened in the lower two
(2) feet of an eleven (11) foot A zone silt bed. Moni-
toring well 14Bj is screened in the lower five (5) feet
of a five and one-half (5.5) foot B^ zone silt bed.
Monitoring well 14C is screened in the lower ten (10)
feet of a fourteen (14) foot C zone sand bed.
The presence of contaminants (organics) were initially
detected in MW 14A in late 1984. Organics were subse-
quently detected in MW's 14A and 14Bi in 1985. Monitoring
wall 14C has not detectd the presence of coTTtanrtnants.
Monitoring wells 14A, 14Bj and 14C were not selected
for sampling for the Task Force evaluation.
-81-
-------
The extent of the contaminants detected in' the A
and Bj zone silt beds at the locations of MW's 14A and
146} have not been assessed.
b. Downgradient Ground-Water Monitoring Wells; 10A and lOBj
MW's IDA and 10B^ - This ground-water monitoring well
cluster was installed in December 1980 and is located at
the intersection of the western and northern limits of the
site waste management area (northwest corner of landfill
717/901). Monitoring well 10A is screened in the lower
five (5) feet of a six (6) foot A zone silt bed. Monitor-
ing well 10B} is screened in the lower foot of a Bi zone
clay bed into the upper four (4) feet of a ten (10) foot
Bi zone silt bed. A Bo zone silt bed is present at the
location of the MW 10 well cluster, however, is not moni-
tored. It has not been determined if a C zone permeable
bed is present at the location of the MW 10 well cluster.
The presence of contaminants (organics) were initially
detected in both MW's 10A and lOBj in 1984 and 1985.
The analytical data resultant of the Task Force evaluation
indicated the detection of contaminants (organics and
inorganics; chromium) only in MW 10A.
The presence of contaminants detected in MW's 10A and
lOBj have not been assessed by Rollins (LA). The depth and
extent of the contaminants remains unknown.
2. Eastern Limit Upgradient Ground-Water Monitoring Wells; 1A,
IB} and 1C, and 2A
-82-
-------
a. MW's 1A, IB^, and 1C - This ground-water monitoring well
cluster was installed in December 1980 and is located in
the northeast corner of the inactive landfarm waste manage-
ment area, approximately two thousand (2,000) feet east
of the location of MW's 6A and 68^ Monitoring well 1A is
screened for five (5) feet in a forty (40) foot A zone
clay bed. The well screen is positioned just below the
midsection of the A zone clay bed. A more permeable silt
and/or sand bed is not present at the location of MW 1A.
Monitoring well 1B1 is screened for five (5) feet, one (1)
foot above the bottom of a fifteen (15) foot B1 zone sand
bed. A B£ zone silt and/or sand bed is not observed at
the location of the MW 1 well cluster. Monitoring well 1C
is screened in the lower ten (10) feet of a seventeen (17)
foot penetration into a C zone sand bed. Total thickness
of the C zone sand bed is unknown.
The presence of contaminants (organics) were detected
in MW 1A in January and November 1981, in MW 1C in 1984, and
in MW's 1A and 1C in 1985. Rollins (LA) attributed the pre-
sence of the contaminants detected in MW 1A in 1981 from
introduction during the drilling and completion of the moni-
toring well. Resultant of a quarterly sampling exercise, a
contaminant (inorganic; lead) was detected in MW 1A in 1984
and 1985. The analytical data resultant of the Task Force
evaluation indicated the detection of the presence of
contaminants (organics) in MW's 1A, IBj and 1C, however,
the concentrations detected were reported below the contract
laboratory detection limits.
-83-
-------
It has not been determined whether the ground-water
samples collected at the location of the MW 1 well cluster
are representative of the background ground-water quality,
the influence from site activities, or an outside source.
Permeable beds within the A and 82 zones are not observed
at this location. The background ground-water quality
should be established for these beds, also. The location
of the MW 1 well cluster may not be appropriate for obtaining
representative background ground-water quality samples.
Should this be determined, the extent of the contaminants
present at the MW 1 well cluster should be determined.
b. MW 2 A- This ground-water monitoring well was installed in
December 1980 and is located at the intersection of the
eastern and southern limits of the site waste management
area (southeast corner of the facility). Monitoring well
2A is screened for five (5) feet in an A zone clay bed.
The presence of contaminants (inorganic; lead and
selenium) were initially detected in MW 2A in 1984. Sub-
sequently, a contaminant (organic) was detected in MW 2A
in 1985. The analytical data resultant of the Task Force
evaluation detected the presence of contaminants (organics)
at the location of MW 2A. However, the concentrations
detected were reported below the contract laboratory
detection limits.
-84-
-------
It has not been determined whether the ground water at
the location of MW 2A has been influenced by site activities
or an outside source. If this is the situation, the extent
of the contaminants beyond the location of MW 2A would need
to be determined. Monitoring well 2A may not be an appropriate
location to obtain a representative sample of the background
ground-water quality.
3. Southern Limit Downgradient Ground-Water Monitoring Well; 3A
MW 3A - This ground-water monitoring well was installed
in December 1980 and is located approximately eight hundred
fifty (850) feet directly east of the MW 4 well cluster.
Monitoring well 3A is located at the downgradient limit of
the inactive landfarm. Monitoring well 3A is screened in
five (5) feet of an A zone clay bed.
The presence of a contaminant (inorganics; lead) was
detected in MW 3A in 1984. The presence of organics
has not been detected. This monitoring well was not
selected for sampling for the Task Force evaluation.
Should it be determined that the ground water at the
location of MW 3A has been influenced by site activities, the
extent of the contamination would need to be assessed.
The following conclusions of the assessment ground-water monitoring system
are resultant of the Task Force evaluation:
-R5-
-------
A. Due to the infrequency of placement of ground-water monitoring wells
at and beyond the downgradient limit of the site waste management area,
the assessment ground-water monitoring system requires upgrading to
adequately assess the extent of the contaminants detected in the
ground water beneath the Rollins (LA) site. This will provide for
the adequate detection and continued monitoring for the presence
of contaminants.
B. The following ground-water monitoring wells require initial assess-
ment, further assessment, and upon further review, the consideration
for assessment of the presence and/or extent of contaminants indicated
at the locations of these ground-water monitoring wells.
1. Initial Assessement

of the A zone to the southeast/southwest of MW 12A has not
been determined.
-87-
-------
k. MW 13A - The presence of contaminants have been detected.
Monitoring wells in proximity to the HW 13 well cluster

detected at the location of this monitoring well. The
extent of the contaminants in the A zone in proximity to
SM3 has not been determined.
2. Further Assessment
MW 11A - The presence of contaminants have been detected. The
A zone in proximity to MW 11A was assessed under the EPA §3013
administrative order with the installation of MW ISA (upgradient
of MW 11A). The extent of the contaminants downgradient of MW
11 has not been assessed.

Interim Status Ground-Water Sampling and Analysis Plan
Rollins (LA) maintains a ground-water sampling and analysis plan detail-
ing the ground-water monitoring system procedures for obtaining samples,
specifically: collection, preparation, and shipment.
Rollins (LA) initially referenced a ground-water sampling and analysis
outline discussed in an April 14, 1981, response correspondence submitted
by Geraghty & Miller, -Inc. Subsequently, sampling and analysis plans were
submitted to the Louisiana Department of Environmental Quality August 1984,
May 1985, August 25, 1986, and October 1986. The latter three (3) plans
were included in the part B hazardous waste management permit applications
and their subsequent revisions.
At the time of the Task Force evaluation, a revised October 1986 ground-
water sampling and analysis plan was currently in effect, therefore, will
be the sole plan discussed for the purposes of this document (reference
Appendix B).
Resultant of the Task Force review of the October 1986 ground-water
sampling and analysis plan (herein referred to as the sampling and analysis
plan), the following deficiencies were recognized:
1) Rollins (LA) presently utilizes the ground-water monitoring wells
listed below to the left. The sampling and analysis plan , however,
references a compliance and detection ground-water monitoring system
comprised of the wells listed below to the right.

The sampling and analysis plan does not reflect the current ground-
water monitoring system utilized for ground-water sample collection
and analyses.
2) The sampling and analysis plan indicates the parameters for analyses
(refer to Table 3 and 4 of the sample and analysis plan) and the fre-
quency of sample collection for the described compliance and detection
ground-water monitoring programs. This sampling and analysis plan does
not reflect the actual parameters that are analyzed or the frequency
of sample collection of the assessment ground-water monitoring system
currently in effect.
3) The schedule for the collection of the ground-water samples is not pro-
vided in the sampling and analysis plan.
-91-
-------
»
4) The sampling and analysis plan does not specify the upgradient and
downgradient ground-water monitoring wells.
5) The sampling and analysis plan does not account for all the ground-
water monitoring wells presently utilized on the Rollins (LA) site,
specifically; MW's 4B2, 9Cr, 11A, llBj and 11C, 16A, UBj and
17B2, 20A, and SMS. These specific ground-water wells were being
sampled quarterly at the time of the Task Force evaluation.
6) Ground-water monitoring well 9Cr is presently in operation and util-
ized by Rollins (LA). However, Table I of the sampling and analysis
plan references the previous ground-water monitoring well 9C, not MW
9Cr. Monitoring well 9C was plugged and abandoned February 1, 1986,
prior to the October 1986 revisions of the sampling and analysis plan,
7) Tables I and II of the sampling and analysis plan provide informa-
tion concerning construction and elevation data for the ground-
water monitoring wells within the compliance and detection ground-
water monitoring programs. The information in Tables I and II are
incorrect for the following:
a. the depth in feet of the well screen placement is provided,
not the elevation of the well screen as labelled.
b. the true elevation of the top of the well casing above mean
sea level is not provided. The elevations provided appear
to be outdated values observed in an August 1984 Geraghty
and Miller, Inc. report; Ground-Water Monitoring and
Corrective Action Programs, Rollins Environmental Services,
Baton Rouge, La.
-92-
-------
c. the correction factor of 3.09 for the ground-water moni-
toring well elevations referenced to true mean sea level
has not been applied.
8) The sampling and analysis plan does not specify that the ground-
water monitoring wells at the Rollins (LA) site are utilized for
assessment ground-water monitoring, only that the wells are members
of either/both the compliance or detection ground-water monitoring
programs.
9) The sampling and analysis plan indicates a triple rinse of distilled
water for sampling equipment that has repeated use in the field.
The decontamination procedures are not specifically outlined in the
plan. It is recommended that all sampling equipment that is not
dedicated and has repeated use in the field should be rinsed with
hexane or an equivalent, followed by a deionized water rinse (parti-
cularly when contact with organics are involved).
10) The sampling and analysis plan does not provide the safety procedures
and precautions practiced for the collection of ground-water samples.
11) The sampling and analysis plan indicates that the ground-water samples
are collected by the method of either well bailers or pumps. The plan
does not specify which method, or types of bailers or pumps are used
for the collection of the ground-water samples from each individual
monitoring well.
12) The sampling and analysis plan explains that to obtain the volume
of ground water to be purged from the monitoring wells, the measured
depth to the water in the well is subtracted from the total depth
-93-
-------
of the well. A table with the total depth of each monitoring
well is not provided. The plan does not specify whether the
reference to the total well depth values are obtained at each
sampling event or representative of the total depths measured
at the time of the installation of the monitoring wells.
13) The sampling and analysis plan does not specify which ground-
water monitoring wells require ground-water "recovery time"
when purging, in order to achieve the sufficient three casing
volumes prior to obtaining a ground-water sample.
14) The sampling and analysis plan does not indicate that the field
equipment (pH and conductivity meters) is standardized immediately
prior to use in order to obtain accurate values.'
15) The sampling and analysis plan references filtering ground-water
samples only when turbidity and/or solids are observed. Rollins
(LA) ground-water samples are currently filtered upon receipt in
the laboratory.
16) The Rollins (LA) field logbook should al-so include the following
significant data; the monitoring well completion data, the purge
volume of ground-water from each monitoring well, subsequent
disposal of the purged ground water, and the ground-water sample
analyses.
17) Attachment number one of the sampling and analysis plan (procedures
for sample preservation and the holding times of the samples)
does not reflect all the parameters analy2ed under the current
Rollins (LA) ground-water monitoring prosram, specifically;
-94-
-------
pesticides, PCB.s radium, gross alpha, chloride, iron, manganese,
phenol, sodium, sulfate, total dissolved solids, antimony, beryllium,
copper, thallium, nickel, zinc, magnesium, and vanadium.
18) The sampling and analysis plan does not explain how the sample
containers are sealed prior to shipment to deter any tampering.
19) The sampling and analysis plan does not mention the holding time
of the ground-water samples prior to delivery, the method
of transportation of the ground-water samples, or which specific
laboratory(s) receives delivery of the ground-water samples.
In conclusion, the ground-water sampling and analysis plan
does not adquately describe the present monitoring program for the
assessment ground-water monitoring system at the Rollins (LA) site.

Rollins (LA) Sampling and Analysis Procedures
(Ground-Water Monitoring)
The Hazardous Waste Ground-Water Task Force has evaluated the ground-
water sample collection and preparation techniques and procedures utilized
at the Rollins (LA) site. In general, Rollins (LA) conducts the sampling
of the ground water in conformance with the guidance and procedures recom-
mended by the Environmental Protection Agency.1 However, several technical
discrepancies were observed.
On November 12, 1986, Rollins (LA) personnel demonstrated ground-water
sample collection, preparation, and shipping techniques and procedures.
This was observed by the Task Force personnel for evaluation.
The following technical discrepancies were recognized and should be
considered for inclusion in the sampling program for the ground-water
monitoring wells:
1. Safety procedures should be stressed and utilized when collecting
and preparing ground-water samples.
2. The total depth of the ground-water monitoring wells should be
determined at the time of sample collection to ensure the integrity
of the well.

3. The samples of ground water for the analyses of the presence of
contaminants are collected by Rollins (LA) personnel in the follow-
ing order; volatile organics, metals, total organic halogen (TOX),
sulfate, chloride, fluoride, total dissolved solids (IDS), gross
alpha and gross beta/radium, semi-volatile organics, total organic
carbon (TOC), phenols, and coliform. It is recommended that the
ground-water samples intended for the analyses of the presence of
organic constituents (volatiles, semi-volatiles, TOC, and TOX)
should comprise the .initial set of samples collected due to the
volatilization sensitivity of these parameters. This will ensure
a representative sample of the ground water.
4. The representativeness of a ground-water sample collected for the
analysis of organics may be compromised when submersible pumps are
utilized to collect the ground water.
Rollins (LA) is referencing an ineffective ground-water sampling and
analysis plan, and the current October 1986 plan does not adequately describe
the present monitoring program for the assessmment ground-water monitoring
system.

Installation And Construction of the Ground-Water Monitoring Wells
The Hazardous Waste Ground-Water Task Force has reviewed and evaluated
the adequacy of the Installation and construction of the ground-water
monitoring wells located at the Rollins (LA) site. The ground-water monitor-
ing wells are generally constructed in a manner suitable for obtaining
representative samples of the ground water beneath the Rollins (LA) site.
However, a condition of what appears to be sediment build-up and/or
casing failure in several of the monitoring wells was recognized. A dis-
cussion of the installation and construction of the Rollins (LA) and the
acquired Allied north tract monitoring wells proceeds.
The Rollins (LA) ground-water monitoring wells were installed under
similar methods, however, the monitoring wells that were completed in the
A, B! and B2 zones (referred to as the shallow and intermediate wells)
have different dimensions than the monitoring wells completed in the C
zone. The C zone monitoring wells are referred to as the deep wells. The
Allied north tract wells which Rollins (LA) acquired with the purchase of
this tract (SM2, SMS, SM4, SMS, and DM3) were completed similarly to
the Rollins (LA) shallow and intermediate monitoring wells, however, only
limited construction details were available.
The shallow and intermediate ground-water monitoring wells were each
installed and completed by the following procedures listed in sequence
(reference Figures 13 and 14 and Table G for the monitoring well construction
diagram and data, respectively):
1. Each borehole was drilled to a desired depth utilizing the mud
rotary drilling method with fresh potable water for the drilling fluid,

2. Two (2) inch diameter casing with a five (5) foot section of well
screen (except MW 20A which has a ten (10) foot screen) was in-
serted in each borehole. The well screens have a No. 8 slot size
(.008 inches). A sump and bottom cap, with a central izer attached,
is situated below the well screen.
Three (3) combinations of well casing and screens were utilized in
the construction for the shallow and intermediate wells, as follows:
a. Monitoring wells 1A and 1B^, 2A, 3A, 4A and 4Bp5A, 6A
and 6B1} 7A and 76^ 8A and 8Bj, 10A and lOBj, and 11A
and HBj are cased with a carbon steel pipe and a stainless
steel well screen. An approximate one (1) foot sump and
bottom cap, with a central izer attached, is situated below
the well screen.
b. Monitoring wells 12A, ISA and 136^ 14A and 14Bj,and
15A and 15B^ are cased and screened with schedule 40
polyvinyl chloride (PVC) pipe. The length of the sump
is not specified.
c. Monitoring wells 4B2> 5Bj, 16A, 17B^ and 17B2» and
20A are cased with PVC pipe and screened with a stainless
steel well screen, No. 10 slot size (.010 inches). An
approximate three (3) foot sump and bottom cap, with a
centralizer attached, is situated below the well screen.
3. Several variations of gravel packs were utilized in the completion
of the ground-water monitoring wells:
-101-
-------
a. The well annul uses adjacent to the well screen in the
monitoring wells described in 2a and 2b above were gravel
packed by the tremie method with a washed uniformly graded
sand. This gravel pack extends approximately one (1) foot
above the top of the well screen. By tremie method, a
fine sand cap was placed above the gravel pack to serve
as a deterrent to the migration of cement into the gravel
pack. The length of the fine sand pack is not specified.
b. The well annul uses adjacent to the well screen in the mon-
itoring wells described in 2c above were gravel packed by
the tremie method with a 20/40 filter sand extending approx-
imately two (2) feet above the top of the screen. By tremie
method, one (1) foot of a fine sand cap was placed above
the gravel pack to serve as a deterrent to the migration
of cement into the gravel pack.
4. The remainder of the well annul uses were then grouted by the tremie
method back to land surface with a Portland Class A cement.
5. The grout was allowed to set at a minimum of sixteen (16) hours,
then, all the monitoring wells were developed for at least four (4)
hours by swabbing/air-lifting the monitoring well.
6. A cap and lock, and steel bar were placed on all the monitoring
wells to deter unauthorized entry.
7. A three (3) inch X three (3) feet X three (3) feet cement pad was
set around each wellhead.
-102-
-------
8. The potential for cross-contamination from the drilling equipment
and associated supplies prior to drilling, and between the drilling
of each well, was prevented by steam cleaning the equipment.
The deep ground-water monitoring wells 1C, 4C, 9C, 9Cr, 11C, and 14C were
constructed by the same methods that were described for the shallow and inter-
mediate wells. However, larger well dimensions and gravel packs that extend
two (2) feet above the top of the well screen were recognized. Also, the well
screen slot size is not specified. Reference Figure 15 and Table G.
i. Monitoring wells 1C, 4C, and 11C were constructed with four (4) inch
diameter carbon steel casing and a ten (10) foot stainless steel screen.
2. Monitoring well 14C was constructed with four (4) inch diameter schedule
40 PVC casing and a ten (10) foot PVC well screen.
According to various well construction diagrams the sumps of the above-
mentioned wells, with a bottom cap attached, are reported to be two (2) feet,
three (3) feet, and five (5) feet in length. The actual lengths of the sumps
for each deep monitoring well is not provided.
3. Monitoring well 9Cr was installed November 27, 1985. This well was
constructed with a four (4) inch diameter schedule 40 flush threaded
PVC casing with a ten (10) foot section of stainless steel well screen
attached; No. 10 slot size. A three (3) foot sump and bottom cap,
with a stainless steel centralizer attached, is situated below the
well screen. By tremie method, the annulus adjacent to the well
screen was gravel packed with a 20/40 filter sand extending nine
(9) feet above the top of the well screen. Two (2) feet of a fine
sand vjas placed above the gravel pack. The fine sand was capped with

annul us was grouted back to land surface with a Portland Class A
cement containing five (5) percent bentonite clay. The grout was
allowed to set at a minimum of twenty-four (24) hours. Monitoring
well 9Cr was then developed by swabbing/air-lifting the monitor well
until clear formation water was pumped from the well. A vented
cap and lockable protective steel casing were installed to deter
unauthorized entry. A three (3) foot square concrete pad was set
around the wellhead (reference Figure 6).
The Allied north tract ground-water monitoring wells (SM2 through SM5,
and DM3) are constructed of two (2) inch diameter PVC casing with a five
(5) foot section of PVC well screen attached. The well screens have a No. 8
slot size. Information concerning the well completion and development was
not available.
Samples of ground water are obtained from the monitoring wells by either
dedicated one (1) inch Teflon® bailers, teflon positive gas displacement
pumps (Well Wizards®), or submersible pumps. Only the ground-water monitor-
ing wells completed in the C zone (1C, 4C, 9Cr, 11C, and 14C) are equipped
with submersible punps. The A, Bj and B2 zone monitoring wells are equipped
with dedicated bailers or Well Wizards.
Rollins (LA) installed thirteen (13) observation wells and eight (8)
piezometers in early spring 1985 to further assess the ground-water hydrology
beneath the site. These wells are strictly utilized by Rollins (LA) to obtain

water level data, and therefore, are not active in the present ground-water
monitoring system. The observation wells were designed to provide water
level data on discrete formation beds within the A and B zones within the
uppermost aquifer. Only observation wells 22A and 31 are screened through
several formation beds. The piezometers were designed to provide water
level data of the A zone within the uppermost aquifer. Installation and
construction of the observation wells and piezometers are as follows
(reference Figure 11 and Appendix F):
1. Observation wells - each well was drilled to a desired depth
utilizing the mud rotary drilling method. Two (2) inch schedule
40 PVC well casing and well screens with threaded couplings were
installed. Two (2) inch schedule 40 PVC sumps (one (1) foot in
length) with screw plugs were attached to the well screens. A
gravel pack was then installed in the well annuluses adjacent to
the well screens by the tremie method.
Bentonite seals ranging from one (1) to five (5) feet were placed
in the well annuluses above the gravel packs, then followed by a
grout consisting of a cement/bentonite mixture which was circulated
back to land surface. The grout was installed by tremie method
and allowed to set for twenty-four (24) hours.
The wells set for a minimum of several days prior to well develop-
ment. Development of the wells was achieved by the air lift method.
Protective surface casing, a concrete pad, and traffic posts surround
the wellheads.
-107-
-------
The following specifics concerning the installation and construction
of the observation wells were not provided; type of drilling fluid
utilized, specification of the well screen slot sizes, and specifi-
cation of the gravel pack.
2. Piezometers - each well was drilled to a desired depth utilizing the
mud rotary drilling method. Two (2) inch schedule 40 PVC well casing
with glued couplings and well screens were installed. Two (2) inch
schedule 40 PVC slip caps (glued) were attached to the bottom of the
well screens. Gravel packs retained by a No. 20 sieve were installed
from land surface into the well annuluses adjacent to the well screens,
These gravel packs extend from four (4) to ten (10) feet above the top
of the well screens. Fine sand was then installed into the well annul-
uses to three (3) to four (4) feet below land surface. The last three
(3) to four (4) feet of the well annuluses were filled with a grout
consisting of a cement/bentonite mixture, which was circulated back
to land surface. Surface casing was then installed at the wellheads.
The following specifics concerning the installation and construction
of the piezometers were not provided; type of drilling fluid utilized,
specifications of the well screen slot sizes, and well development
procedures.
In conclusion, the present ground-water monitoring wells were generally
installed (drilling and completion) with procedures suitable for obtaining
representative samples of the ground water beneath the Rollins (LA) site.
However, the following condition of what appears to be sediment build-up
and/or casing failure in several of the ground-water monitoring wells could
possibly influence the quality of the ground-water samples.
-108-
-------
Resultant of the Task Force evaluation, the total depth of the ground-
water monitoring wells, the observation wells, and the piezometers
were measured in the field (well conditions permitting). Records
concerning the actual length of well sumps and the total depth of the
wells were possibly never generated and/or were not maintained. The
Task Force data indicates that several ground-water monitoring wells,
observation wells, and piezometers have a recorded screen depth (at
the time of installation) that exceeds the current measured total
depth of the respective well (reference Table G).
A build-up of sediments in the well and/or a well casing failure could
create conditions that may hinder the collection of a ground-water sample
from the appropriate formation bed. This could influence the quality of the
ground-water sanple.
In the future, should Rollins (LA) install additional RCRA ground-water
monitoring wells, the following items should be taken into consideration:
1. Specify the construction material of all the sections of the
ground-water monitoring well.
2. Document all phases of the ground-water monitoring well develop-
ment for future reference concerning adequate well development.
3. Specify the type and length of all fill materials utilized to
seal the ground-water monitoring well annulus.
4. Specify the depth at which the ground-water monitoring well pumps
are placed.
5. Maintain records of all routine ground-water monitoring well main-
tenance and "workovers".

Evaluation of the Rollins (LA) Contract Laboratory
Rollins (LA) currently utilizes the services of Toxicon Laboratories,
Inc. (Toxicon) Baton Rouge, Louisiana for the analyses of the samples of
ground water that are collected.
Toxicon is subject to laboratory audits conducted by the Environmental
Protection Agency. The laboratory audit consists of an evaluation of anal-
ytical equipment and methods, quality assurance procedures, and documentation.
The laboratory records are evaluated for completeness, accuracy, and compliance
with state and federal requirements. Personnel of the Environmental Protection
Agency Region VI, Environmental Services Division (Houston Branch) conducted
a laboratory audit (for organics analyses) of Toxicon prior to the November
1986 Task Force evaluation of Rollins (LA). Due to this inspection, the
Task Force did not conduct an audit of Toxicon at the time of the evaluation.
The laboratory audit concerning the quality assurance of the organic
analyses was conducted on May 9, 1986, and is referenced by the Task Force
in Appendix G. The evaluation report states that the overall laboratory
facilities were adequate to accomplish the objectives of analyzing ground
water for the presence of organics.

Analytical Results of the Samples Collected
by the Hazardous Waste Ground-Water Task Force
The Hazardous Waste Ground-Water Task Force has reviewed the Task Force
analytical results of the preselected samples collected at the locations of
the Rollins (LA) ground-water monitoring wells, and the landfill 717 leak
detection and leachate collection systems. The analytical results of the
samples obtained are outlined below (reference Appendix C).*
During the Task Force evaluation (November 10 through 20, 1986) samples
of the ground water were collected across the Rollins (LA) site, as well
as, samples of the liquids from the landfill 717 leak detection and
the leachate collection systems.

3. A ground-water sample was collected at the location of the facility
process water well.
4. A ground-water sample was collected at the location of the observation
well OB 33.
5. Liquid samples were collected from the landfill 717 leak detection
system at the locations of leak detection wells Dg and Dy.
6. A liquid sample was collected from the landfill 717 leachate
collection system.
7. An equipment blank, trip blank, and two (2) field blanks were
prepared also.
The samples collected were analyzed for the presence of the contaminants
which comprise the Hazardous Substance List, as well as, other various metals
and inorganics, (reference Appendix D):
1. Orgam'cs
a. Ground water, liquids, and leachate were collected at the locations
of select ground-water wells, landfill 717 leak detection wells, and
a landfill 717 leachate collection well. The presence of contaminants
(organics) were detected above the contract laboratory detection
limits at the following wells:
6B, I3
10A DC (leak detection)
13A Landfill 717 leachate
13B1

b. Ground water, liquids, and leachate were collected at the locations
of select ground-water wells, landfill 717 leak detection wells, and
a landfill 717 leachate collection well. The presence of contaminants
(organics) were detected, however, at concentrations below the contract
laboratory detection limits at the following wells:
1A 11A
1C ISA
2A 13B,
6A IBB;
6Bi 20A
8A SMc
8B1 !3
9Cr DC (leak detection well)
10A Dy
Landfill 717 leachate
2. Inorganics (metals only)
Ground water, liquids, and leachate were collected at the locations
of select ground-water wells,landfill 717 leak detection wells, and a
landfill 717 leachate collection well. The presence of contaminants
(inorganics) were detected at a concentration above the interim primary
drinking water standards at the following wells:
8Bj I3
10A D7
11A OB 33
SMS Landfill 717 leachate
Due to the presence of contaminants in the ground water, Rollins has
been involved (since 1981) in a ground-water recovery program which includes
five ground-water recovery wells, 1^ through 15,and on-site ground-water
treatment facilities.
The Task Force analytical data is subject to a rather entensive quality
assurance/ quality control (QA/QC) review. As a result of this review, an
evaluation concerning the reliability and usability of the analytical data
has been summarized into a report presented in Appendix H.

of contaminants in these

This order is currently

Status
The land-
farm is
not subject
to RCRA

lations.
Wastes
Accepted
dous wastes not
exhibiting the
characteristics
of reactivity,
corrosivity, or
ignitability.
The liquid
hazardous
wastes are
stabilized
with flue dust
prior to dis-
posal in the
landfill.
The 1 andfarm
received K048
wastes and
wastewater
sludge exclu-
sively from
one (1) local
refinery.
Date of
Operation
Prior to the
construction
of this fa-
cility, sta-
bilization
of some of
the liquid
hazardous
wastes was
conducted in
the portion
of the land-
fill that
was active
at that
particular
time.
The 1 andfarm
was placed
in service
prior to
1980 and is
currently
active.

Construction
(if appl i cable)
surrounded by compacted
sand, then an HPDE syn-
thetic liner. The leak
detection pipe consists
of a filter cloth
covered perforated PVC
pipe embedded in the
compacted sand.
The 1 andfarm is clay
capped, however, not to
any particular specifi-
cations. This cap was
seeded and is currently
grass covered. A drain-
age ditch, exclusive
to each of the two (2)
1 andfarm sections, sur-
rounds each one. At the
time of the Task Force
evaluation, significant
erosion cracks were
observed on the sloped
sides of the north
section of the 1 andfarm.
Remarks
addressed the presence
of contaminants in the
Landfill 717 leak detec-
tion well system. The
presence of contami-
nants were detected.'
Rollins (LA) has pro-
posed the cleanup and
restoration of the
mixing tanks.
The 1 andfarm was util-
ized exclusively for
the treatment of the
listed petroleum
refining hazardous
waste; K048, and waste-
water sludge. In
response to a June 17,
1981 settlement of
agreement between
Rollins (LA) and the
Louisiana Environmental
Control Commission,
operation of the
1 andfarm ceased
December 1981. The

(if appl icable)
Some erosion was observ-
ed on the north side of
the south section of the
land farm, however, not
as severe.
Rollins (LA) has esti-
• mated that the- acid
cell, carbon area, and
the 200 and 400 series
cells are irregular in
shape and generally
fifteen (15) to twenty
(20) feet deep. The
Hy Purle area is approx-
imately 425' x 420' x
6' deep. Cell 611B is
approximately 85' x 85'
x 20' deep. Cells 619
and 719 are both appro-
ximately 200' x 80' x
35 to 40' deep. All the
landfill cells are
unlined. The landfill
cells have all been
earthen covered and
seeded.
Remarks
company generating the
K048 waste, that was
disposed at the Rollins
(LA) landfarm, was sub-
sequently granted a
delisting of the waste
by the Environmental
Protection Agency.
These twenty-five (25)
landfill cells are all
that remain of approx-
imately one hundred
eight (108) solid waste
management units (cells/
basins) utilized prior
to the construction of
Landfill 717. It has
not yet been determined
whether these remaining
cells will be excavated
or left intact due to
the presence of con-
taminants in the ground
water beneath the
Rollins (LA) site
(reference Figures
2 and 6).

GROUND-WATER SAMPLING t ANALYSIS PLAN
This sampling and analysis plan has been developed by
Geraghty & Miller, Inc. (G&M) to describe the procedures and
techniques which must be followed at Rollins Environmental
Services La., Inc. (RES(LA)) during the collection and
analysis of ground-water samples at their site in Baton
Rouge, Louisiana. This plan has been designed in accordance
with the requirements of Louisiana Hazardous Waste
Regulations (LHWR) and specifies detailed procedures for
proper sample collection, preservation and shipment,
analytical procedures, and chain-of-custody control. The
detection monitoring network is shown in Figure 1, and the
construction details for these monitor wells are provided in
Table 1. The compliance monitoring network is shown in
Figure 2, and the construction details for these monitor
wells are provided in Table 2.
SAMPLE COLLECTION PROCEDURES
Monitoring Parameters and Monitoring Frequency
The monitoring parameters selected by RES(LA) for
detection monitoring purposes are shown in Table 3.

monitoring wells shown in Figure 1 semi-annually and should
be analyzed for these parameters. The RES(LA) compliance
monitoring parameters are shown in Table 4. Ground-water
samples should be collected from the compliance monitoring
network shown in Figure 2 on a quarterly basis and should be
analyzed for these parameters.
The sampling schedule may be revised; as necessary,
after reviewing the results of the analyses of a sampling
event.
Equipment Inventory and Well-Site Preparation
A checklist of sampling equipment is provided in Table
5. An equipment inventory should be conducted prior to
t
sampling to ensure the availability of adequate sampling
equipment and accessories. The following procedures should
be performed immediately prior to each sampling event:
(1) Equipment which will come in contact with the
ground-water sample should be rinsed three times with
distilled water.
(2; pH and conductivity meters should be calibrated
with fresh standards being obtained at least every six
months.
(3) Sample containers should be cleaned and preserved
according to the requirements listed in Attachment 1.

Upon arriving at the well site, the cap should be
_' removed from the well and the well should be allowed to
"breathe", for ten to twenty minutes. This will allow the
water level to stabilize. Plastic sheeting should be placed
around the well to protect sampling equipment from potential
contamination. The preliminary information requested in the
field sampling log (i.e. time, date, weather, etc.), shown in
Attachment 2, should be recorded at this time.
Water Level Measurement
The ground-water monitoring program should include a
determination of the ground-water surface elevation each time
ground-water is sampled. Water level measurement should
be collected with an "M-scope" as follows:
1) The probe should be slowly dropped down the
center of the casing and allow the cord to go
untangled down the well.
2) When a closed electrical circuit is indicated
by the ammeter, the cable should be held at
the top of the outer metal casing.
3) Record the measurement, which is the depth to
water.
4) The ground-water surface elevation is found by
subtracting the depth to water from the top of
casing elevation.
VI-8-12
-------
Gcraghty & Miller, Inc
Removal of Standing Water
Standing water must always be removed from the well bore
prior to collecting ground-water samples. Three well volumes
are recommended to be removed to ensure a sample
representative of the ground-water quality in the immediate
vicinity of the monitor well is obtained. The well volume
can be calculated by:
V« 7.48 •> r2h
V= Volume of Standing Water (Gallons)
7.48* Conversion Factor (Ft - Gallons)
TT * 3.14
r* Radius of Well Casing (Ft)
h= Height of Standing Water (Ft)
The Volume, V, is equal to .163 times the height, h, of
standing water in the 2-inch diameter monitor wells and .653
times the height in the 4-inch diameter monitor wells. The
height of standing water in the well is obtained by
subtracting the measured depth to the water from the total
depth of the well.
Th~e three well volumes, of water, which are removed from
the well, must be discarded properly "to avoid potential
contamination. Proper care must be taken to prevent spillage
when transferring this water from the pump (or bailer) to the
VT-S-13
-------
Gcraghcy & Miller, Inc
s portable container provided. This container should be
transported to Basin 302 to be emptied.
When using the pump to remove three well volumes of
standing water, the outflow should be monitored by observing
the time since pumping was initiated. The volume of water
removed is obtained by multiplying the flow rate of the pump
times the time since pumping was initiated. In the situation
where a well is pumped dry, record the volume removed and
shut the pump off until sufficient recharge has occurred to
resume pumping the remaining volume before collecting the
ground-water sample.
Field Analysis and Sample Collection
s
Analyses of pH, temperature, and specific conductance
should be made in the field at the time of sampling because
these parameters change rapidly and a laboratory analysis
might not he representative of the true ground-water quality.
Approximately one half-gallon of sample should be placed in a
clean, unpreserved glass container and these field
measurements should be collected from this sample. These
values should be recorded on the field sampling log.
VI-8-14
-------
Gcraghty & Miller, Inc.
Sample containers should be filled directly from the
discharge line (or bailer). Extreme care should be taken to
fill the containers slowly so that the sample is not agitated
during the transfer in order to limit the amount of oxygen
added to the sample. Sample containers should be completely
filled, but should not be rinsed prior to sample collection.
Samples collected for volatile organic analyses should not
have any headspace or air pockets in the vials. To eliminate
• the headspace, the containers should be filled slowly to the
very lip of the container so that a miniscus if formed. The
lid of the container should be placed evenly over the top of
the container and then screwed on.
Samples with a visible accumulation of solids or turbid
samples should be filtered prior to acidification
(preservation) and analyses. Filtration should be conducted
in the field using either a funnel lined with a clean 40
micron filter or a back-to-back filtering device in which the
sample is pumped through a primary coarse filter and then a
secondary fine filter and ultimately into the sample
containers. If in-situ filtration is not possible, samples
should be collected in unpreserved containers and taken
immediately to the laboratory for filtration and then
preservation. ~~ — -
VI-8-15

Gcraghty & Miller, Inc.
» SAMPLE PRESERVATION, SHIPMENT AND ANALYSIS
Attachment 1 presents container and preservation
requirements which should be followed. Exposure of samples
t
to excessive heat or sunlight in the field should be
minimized. The samples should be placed in ice chests
immediately following collection and should be delivered to
the laboratory as soon as possible. Samples should be
refrigerated at 4 C during laboratory storage prior to
analyses.
Ground-water samples will be analyzed for the parameters
listed in Tables 3 and 4. The analytical methods which must
be used to measure these parameters in the laboratory are
1 referenced in Attachment 3. Each of these methods are EPA
approved and the laboratory must implement all appropriate
quality controls. ' The samples must be analyzed within the
holding times specified in Attachment 1.
RECORDKEEPING
Persons involved in sample collection (hereinafter
referred to as the Samplers) must document the handling
history of the ground-water samples. The recordkeeping
procedure includes a checklist to ensure that the integrity
of the sample is being maintained from time of sample
collection through analysis and final disposition.
VI-8-16
-------
Gcnghty & Miller, Inc
Sample Labels
Sample labels are necessary to prevent misidentification
of the samples. The labels should be affixed to the sample
containers prior to the time of sampling. The labels should
be filled out at the time of collection. The labels should
include the following information:
1) Sample Number
2) Name of Collector
3) Date and Time of Collection
4) Place of Collection
Sampling Log
RCS(LA) should maintain a field sampling log book to
record information about each sample collected during the
ground-water monitoring program. The field log should be
completed at time of sampling. It will provide a source of
documentation to indicate whether sampling reguirements have
been met. A field sampling log is shown in Attachment 2.
Chain-of-Custody
Samplers must complete chain-of-custody forms to
*
establish the documentation necessary to trace sample
possession from time of collection to analysis. A
chain-of-custody form is shown in Attachment 4.

TABLE KEY
A value without a flag indicates a result above the contract
required detection limit (CRDL).
Indicates an estimated value. This flag is used either when
estimating a concentration for tentatively identified compounds
•where a 1:1 response is assumed or when the mass spectral data
indicated the presence of a compound that meets the identification
criteria but the result is less than the specified detection limit «
but greater than zero. If the limit of detection is 10 vg «nd a
concentration of 3 pg is calculated, then report as 3J.
This flag is used when the analyte is found in the blank as well as
a sample. It indicates possible/probable blank contamination and
warns the data user to take appropriate action.
GW - ground-water
SW m surface-water
low and medium are indicators of concentration.

This memo summarizes the evaluation of the quality control data generated
by the Hazardous Waste Ground-Water Task Force (HWGWTF) contract analytical
laboratories (1). This evaluation and subsequent conclusions pertain to the
data from the Rollins, Louisiana sampling effort by the Hazardous Waste Ground-
Water Task Force.
The objective of this evaluation is to give users of the analytical data a
more precise understanding of the limitations of the data as well as their
appropriate use. A second objective is to identify weaknesses in the data
generation process for correction. This correction may act on future analyses
at this or other sites.
The evaluation was carried out on information provided in the accompanying
quality control reports (2-3) which contain raw data, statistically transformed
data, and graphically transformed data.
* HWGWTF Data Evaluation Committee Member
-------
'•_. . iflc C' iluation process consisted of three steps. Step one consisted of
- generation of a package which presents the results of quality control
--^_procedures, including the generation of data quality indicators, synopses of
statistical indicators, and the results of technical qualifier inspections. A
____report on the results of the performance evaluation standards analyzed by the
laboratory was also generated. Step two was an independent examination of the
quality control package and the performance evaluation sample results by
— - members of the Data Evaluation Committee. This was followed by a meeting
(teleconference) of the Data Evaluation Committee to discuss the foregoing data
and data presentations. These discussions were to come to a consensus, if
possible, concerning the appropriate use of the data within the context of the
HWGWTF objectives. The discussions were also to detect and discuss specific or
general inadequacies of the data and to determine if these are correctable or
inherent in the analytical process.
- Preface
The data user should review the pertinent materials contained in the
accompanying reports (2-3). Questions generated in the interpretation of these
data relative to sampling and analysis should be referred to Rich Steimle of
the Hazardous Waste Ground-Water Task Force.
I. Site Overview
No background information concerning the Rollins, Louisiana facility was
available to the HWGWTF Data Evaluation Committee teleconference.
Thirty-six field samples including two field blanks (MQA811/Q1468 and
MQ0872/QO872), one equipment blank (MQO866/QO866), one trip blank
(MQO861/QO861), and three pairs of duplicate samples (well 8B, samples
MQA796/Q1453 and MQA799/Q1456, well 13A, samples MQO871/QO871 and MQO879/QO879,
and well 13B, samples MQO875/QO875 and MQO876/QO876) were collected at this
facility. Sample MQA805/Q1462 was specified by the sampling team as a medium
concentration leachate sample and samples MQA809/Q1466 and MQA810/Q1467 were
specified as medium concentration ground-water samples. All other samples were
specified as low concentration ground-water samples. In the following -
discussions of the data, all mention of "low" or "medium" concentration samples
refers only to the sampling team's designation of the sample, not the actual
concentration of analytes found in the sample.
II. Evaluation of Quality Control Data and Analytical Data
1.0 Metals
1.1 Performance Evaluation Standards
Metal analyte performance evaluation standards were not evaluated in
conjunction with the samples collected from this facility.
1.2 Metals OC Evaluation
Total metal spike recoveries were calculated for twenty-three metals
spiked into two, of three possible, low concentration ground-water samples
(MQO799, 871, and 879) and one (of two) medium concentration leachate samples
-------
(MQO809 and 810). Not all metals were spiked into each of these samples.
Nineteen of the twenty-three average spike recoveries from the low
concentration ground-water samples were within the data quality objectives
(DQOs) for this Program. The aluminum, antimony, cadmium, and iron average
spike recoveries were outside DQO with values of 42, 197, 137, and 20 percent,
respectively. Various individual metal spike recoveries from the ground-water
samples were also outside DQO. These are listed in Table 3-2a of Reference 2
as well as in the following Sections. A listing of which samples were spiked
for each analyte is also available in Table 3-2a of Reference 2.
Seventeen of the twenty-three spike recoveries from the medium
concentration spiked samples were within Program DQOs. Only one sample was
spiked for each metal in the medium concentration matrix. In the medium
concentration sample the antimony, mercury, and selenium spike recoveries were
outside DQO with values of 1038, 130, and 134 percent, respectively. The
arsenic, manganese, and zinc spike recoveries were not calculated because the
sample concentrations of these metals were greater than four times the
concentration of the spike.
The calculable average relative percent differences (RPDs) for all
metallic analytes in the low concentration ground-water samples, except for
aluminum, were within Program DQOs. The calculable RPDs for all metallic
analytes in the medium concentration samples, except for arsenic, were within
the DQOs. RPDs were not calculated for about one-half of the metal analytes
because the concentrations of many of the metals in the field samples used for
the RDP determination were less than the CRDL and thus were not required, or in
some cases, not possible to be calculated.
Required analyses were performed on all metals samples submitted to the
laboratory.
No metals contamination was reported in the laboratory blanks. A trip
blank (MQO861) contained 278 ug/L of aluminum which is above the aluminum CRDL
of 200 ug/L. All four of the sampling blanks contained metal contamination at
levels between the instrument detection limit and the CRDL. This contamination
included aluminum (equipment blank), barium (equipment and trip blanks),
calcium(all blanks), cobalt (equipment and one field blank), iron (trip and one
field blank), manganese (trip and one field blank), potassium (equipment and
one field blank), and sodium (trip, equipment, and one field blank).
1.3 Graphite Furnace Metals
The graphite furnace metals (antimony, arsenic, cadmium, lead, selenium,
and thallium) quality control, with exceptions, was acceptable.
Duplicate injection precision for arsenic was poor for medium
concentration sample MQA809. Based upon the analytical results, it was not
possible to determine if arsenic was present in this sample. High levels of
dissolved solids may have caused an interference. Arsenic results for the
medium concentration samples (MQA805, 809, and 810) should be considered semi-
quantitative.
All graphite furnace metal matrix spike recoveries fall within the 75 to
125 percent recovery DQO with the exceptions of the six listed below. Both
-------
_; -antimony matrix spike recoveries in the low concentration spiked samples,
~~: 1MQO879 and MQA799 were above DQO with values of 176 and 218 percent,
respectively. The cadmium and selenium matrix spike recoveries for one of the
two low concentration samples, MQO871, were also above DQO with values of ISO
r and 129 percent, respectively. The antimony matrix spike recovery from sample
MQA809 and the selenium spike recovery from sample MQA810, both the only spike
of these metals into medium concentration samples, were above DQO with
recoveries of 1038 and 134 percent, respectively. All results for antimony,
t cadmium and selenium in the low concentration samples and antimony and selenium
' in the high concentration samples are expected to be biased high due to the
high spike recoveries. All positive antimony results in either matrix should
not be used. All positive cadmium and selenium results in the low
1 concentration samples and all positive selenium results in the medium
concentration samples should be considered semi-quantitative.
: The correlation coefficient for the method of standard addition (MSA)
analysis of antimony in sample MQA806, cadmium in sample MQO877, and lead in
samples MQO871, MQA795, 796, and 810 were outside of DQO. Antimony results for
sample MQA806 and lead results for sample MQA810 should not be used. Cadmium
i results for sample MQO877 and lead results for samples MQO871, MQA795, and 796
should be considered qualitative.
The duplicate injection precision for selenium for sample MQA803 was poor.
Selenium results for this sample should not be used.
: In summary, all thallium results should be considered quantitative.
Antimony, arsenic, cadmium, lead, and selenium results, with exceptions listed
below, should also be considered quantitative. Arsenic results for samples
MQA805, 809, and 810, cadmium results for samples MQO862, 863, 877, 879,
1 MQA794, 795, 799, 800, 803, and 808, and selenium results for samples MQA802,
805, 809, and 810 should be considered semi-quantitative. Cadmium results for
; . sample MQO877 and lead results for samples MQO871, MQA795, and 796 should be
| considered qualitative. Antimony results for sample MQA805, lead results for
* sample MQA810, and selenium results for sample MQA803 should not be used.
1.4 ICP Metals
I
The trip blank, MQO861, contained 278 ug/L of aluminum which is greater
than the aluminum CRDL of 200. Due the contamination found in the trip blank,
the aluminum results for samples MQA801, 804, 805, 810, 815, 861, 863, 864,
867, 875, and 876 should be considered unusable and results for samples MQA808
and MQO873 should be considered qualitative. See Note (1) at the end of this
Report for a discussion of the usability of results where blank contamination
was present.
The low level (twice CRDL) linear range check for chromium had poor
recovery. The low level linear range check is an analysis of a solution with
elemental concentrations near the detection limit. The range check analysis
shows the accuracy which can be expected by the method for results near the
detection limits. The accuracy reported for chromium is not unexpected. All
chromium results except for sample MQO865 were affected and should be
considered to be biased low by approximately 40 to 55 percent.
-------
- -Individual matrix spike recoveries were outside DQO for aluminum, iron,
—and zinc in low concentration matrix sample MQO869 with 42, 20, and 126 percent
recoveries, respectively. All low concentration matrix aluminum and iron
results, both with exceptions, should be considered qualitative. All low
concentration matrix zinc results should be considered semi-quantitative. Low
spike recoveries are usually indicative of results which are biased low and
high spike recoveries are usually indicative of results which are biased high.
The TCP serial dilution results were not within 10 percent of the original
determination for aluminum in sample MQO879. Poor serial dilution results can
T)e an indication of physical interferences in the analyses. Such interferences
usually yield results with a negative bias and thus a low recovery. This
result caused no add:tional impact on the data quality as the aluminum data
were already judged to be qualitative.
Laboratory duplicate results for aluminum in samples MQO879 and MQA799
were outside DQO. Again, this result caused no additional impact on the
aluminum results.
The field duplicate precision for two of the aluminum (MQA796/799 and
MQO871/879) and one of the iron duplicate pairs (MQO871/879) was poor with RPDs
of 80, 48, and 43 percent, respectively. See Note (2) at the end of this
Report for a discussion of why field precision results are not used in the
determination of data quality.
All barium, beryllium, calcium, chromium, cobalt, copper, magnesium,
manganese, nickel, potassium, silver, sodium, and vanadium results should be
considered quantitative. Aluminum results for sample MQA809, iron results for
samples MQA805, 809, and 810 and zinc results for samples MQA807, MQO814, 815,
863, 864, and 874 should also be considered quantitative. Zinc results, with
the above mentioned exceptions, should be considered semi-quantitative.
Aluminum and iron results, with exceptions, should be considered qualitative.
Aluminum results for samples MQA801, 804, 805, 810, MQO815, 861, 863, 864, 867,
875, and 876 should be considered unusable due to blank contamination at
similar concentrations. Iron results for sample MQO814 should also be
considered unusable.
1.5 Mercury
Individual matrix spike recoveries were outside DQO for mercury in low
concentration matrix sample MQA799 and medium concentration matrix sample
MQA809 with 60 and 130 percent recoveries, respectively. All low concentration
matrix mercury results should be considered semi-quantitative. All medium
concentration matrix mercury results should be considered quantitative. Low
spike recoveries are usually indicative of results which are biased low and
high spike recoveries usually indicate results which are biased high.
2.0 Inorganic and Indicator Analvtes
2.1 Performance Evaluation Standard
Inorganic and indicator analyte performance evaluation standards were not
evaluated in conjunction with the samples collected from this facility.
-------
2.2 IspXRfiTic and Indicator Analvte OC Evaluation
The average spike recoveries ot all of the inorganic and indicator
analytes, except for chloride in the low concentration matrix samples and POX,
nitrate nitrogen, sulfate, and chloride in the medium concentration matrix
sample, were within the accuracy DQOs (accuracy DQOs have not been established
for bromide and nitrite nitrogen matrix spikes). The chloride average spike
recovery was 56 percent in the low concentration matrix sample. The nitrate
nitrogen, sulfate, and chloride spike recoveries (only one sample was spiked
for this matrix) were 72, 0 (no recovery), and 10 percent in the medium
concentration matrix sample. The bromide and nitrite nitrogen average spike
recoveries were 115 and 111 percent in the low concentration matrix samples and
not applicable for bromide (spike added was less than four times sample result)
and 0 percent (no recovery) for chloride in the medium concentration matrix
sample.
Average RPDs for all inorganic and indicator analytes were within Program
DQOs except for TOC in the medium concentration matrix sample. The TOC RPD in
the medium concentration matrix sample was 11 percent (the DQO is 10 percent).
Precision DQOs have not been established for bromide and nitrite nitrogen.
Requested analyses were performed on all samples for the inorganic and
indicator analytes.
No laboratory blank contamination was reported for any inorganic or
indicator analyte. Sampling blank contamination involving TOX was found in the
both field blanks and the trip blank at levels above CRDL. These contaminants
and their concentrations are listed below, as well as in Section 3.2.4 (page 3-
3) of Reference 2.
2.3 Inorganic and Indicator Analvte Data
All results for cyanide, ammonia nitrogen, and total phenols should be
considered quantitative with an acceptable probability of false negatives.
The matrix spike recovery for nitrate nitrogen from the medium •
concentration matrix sample was below DQO with a value of 72 percent. The
holding times for the nitrate and nitrite nitrogen analyses ranged from 10 to
11 days from receipt of samples which is longer than the recommended 48 hour
holding time for unpreserved samples. Nitrate and nitrite nitrogen results
should be considered semi-quantitative.
The matrix spike recoveries for chloride from one of two low concentration
and the one medium concentration matrix spiked samples were below DQO with
values of 0 (no recovery) and 10 percent, respectively. There are probably
negative interferences with the detection of the chloride ion. All chloride
results should be considered qualitative and under reported based upon low
matrix spike recoveries.
The matrix spike recovery of bromide from one of two low concentration
matrix spiked samples was above DQO with a value of 120 percent. Low
concentration matrix bromide results should be considered quantitative with a
slightly high bias. Medium concentration matrix bromide results should be
considered quantitative.
-------
The matrix spike recoveries for su3rr.<.e from both of the low concentrati;..
the one medium concentration matrix spiked samples were outside DQO with
values of ">0, 180 and 0 percent (no recovery), respectively. Low concentration —
matrix sulfate results should be considered qualitative with positive and
negative interferences causing an unknown bias. Medium concentration matrix
sulfate results should be considered qualitative with a very low bias. One of
three sets of field duplicates (MQO871/879) showed poor precision with POC
concentrations of 190 and 76 mg/L reported. See Note (2) at the end of this
Report for a discussion of why field precision results are not used in the
determination of data quality.
The TOC laboratory duplicate RPD for sample MQA809 (a medium concentration
matrix sample) was above DQO. One of the three sets of field duplicates
(MQO871/879) also had a large RPD with TOC concentrations of 8.8 and 51 mg/L
reported. See Note (2) at the end of this Report for a discussion of why field
precision results are not used in the determination of data quality. The low
concentration matrix TOC results should be considered quantitative and the
medium concentration matrix TOC results should be considered semi-quantitative.
Calibration verification standards for POC were not analyzed. A POC spike
solution was run during the analytical batch but the "true" value of the spike
was not provided by the laboratory. EPA needs to supply the inorganic
laboratory with a POC calibration verification solution. Until then, the
instrument calibration can not be assessed. One of four low concentration POC
matrix spikes was below DQO with a recovery of 74 percent. This was not
judged to affect overall data quality as results for the other three matrix
spikes were acceptable. One of three sets of field duplicates (MQO871/879)
showed poor precision with POC concentrations of 110 and 15000 ug/L reported.
See Note (2) at the end of this Report for a discussion of why field precision
results are not used in the determination of data quality. POC holding times
ranged from 5 to 10 days. Although the EMSL/Las Vegas data reviewers recommend
a seven day holding time, the laboratory has been instructed by the EPA Sample
Management Office that a 14 day holding time is acceptable. The POC results
should be considered qualitative.
Both of the field blanks and the trip blank contained TOX contamination at
levels of 9.2, 36, and 11 ug/L which are greater than the CRDL (5 ug/L). The
TOX results for samples MQA798, MQO876, and 878 should be considered
qualitative, and TOC results for samples MQA795, 796, 797, 799, 800, 801, 802,
806, 807, 808, 811, MQO814, 862, 863, 864, 865, 872, and 874 should not be
used. See Note (1) at the end of this Report for a discussion of the usability
of results where blank contamination was present. TOX samples MQA803, 805,
809, 810, MQO871, and 879 contained concentrations of chloride above 500 mg/L
which may have enhanced the TOX results for this sample. The results for all
TOX three pairs of field duplicates showed poor precision with RPDs of 41, 42,
and 75 percent. See Note (2) at the end of this Report for a discussion of why
field precision results are not used in the determination of data quality. The
date of run number 10 was not indicated in the raw data. This did not affect
the data quality. The TOX results should be considered quantitative except for
samples MQA798, MQO876, and 878 which should be considered qualitative and
samples MQA795, 796, 797, 799, 800, 801, 802, 806, 807, 808, 811, MQO814, 862,
863, 864, 865, 872, and 874 which should be considered unusable due to blank
contamination.

3.0 Organics and Pesticides
3.1 Performance Evaluation Standard
Organic performance evaluation standards were not evaluated in conjunction
with the samples collected from this facility.
- 3.2 Organic OC Evaluation
All matrix spike average recoveries were wiihin established Program DQOs
for accuracy. Individual matrix spike recoveries which were outside the
accuracy DQO will be discussed in the appropriate Sections below. All
surrogate spike average recoveries were within DQOs for accuracy with the
; exception of the semivolatiles for the medium concentration surrogate spike
samples which were diluted out during sample preparation. Surrogate spike
recoveries which were outside the accuracy DQO will be discussed in the
j appropriate Sections below.
All matrix spike/matrix spike duplicate average RPDs were within Program
DQOs for precision. Individual matrix spike RPDs which were outside the
j precision DQO will be discussed in the appropriate Sections below. All average
surrogate spike RPDs were within DQOs for precision.
All organic analyses were performed as requested.
Laboratory blank contamination was reported for organics and is discussed
in Reference 3 (for organics) as well as the appropriate Sections below.-
Detection limits for the organic fractions are summarized in Reference 3
(for organics) as well as the appropriate Sections below.
3.3 Volatiles
Quality control data indicate that volatile organics were determined
acceptably. The chromatograms appear acceptable. Initial and continuing
calibrations, tunings and mass calibrations, blanks, matrix spikes and matrix
spike duplicates (with one exception), surrogate spikes, and holding times were
acceptable.
The benzene matrix spike and matrix spike duplicate recovery for sample
' QO879 were 60 and 54 percent, respectively, which are below the DQO for
benzene. As benzene was detected in sample QO879, the benzene recovery for the
sample should be considered to be biased low.
-------
"Estimated method detection limits were CRDL for ail samples except QO875
(2 times CRDL), QO876 (2 times CRDL), Q1460 (17 times CRDL), Q1462 (417 times
r^~T % ^ ««* <143 ,;,,,.. CFTM_), aad Q1467 (5 times CRDL). Dilution of these
samples was required due 10 high concentration of organics.
Five laboratory blanks contained methylene chloride contamination and two
also contained acetone contamination. These common laboratory contaminants
were present at levels below the CRDL but above the instrument detection limit.
Acetone results for sample QO879 and methylene chloride results for samples
Q1452, 1453, 1455, and 1456 should not be used due to this laboratory blank
contamination. .
The volatiles data are acceptable. The volatile compound results should
be considered quantitative with exceptions. False negatives for the medium
concentration matrix samples (Q1460, 1462, and 1466) should be considered a
possibility due to large sample dilutions. Any positive or negative results
for benzene and other simple aromatic compounds in the low concentration matrix
samples should be considered semi-quantitative with a low bias due to poor
benzene recovery. Acetone and methylene chloride results for the samples
mentioned above should not be used due to laboratory blank contamination. The
probability of false negative results for all other compounds in all low
concentration samples is acceptable.
3.4 Semivolatiles
Initial and continuing calibrations, tuning and mass calibrations, blanks,
matrix spikes and matrix spike duplicates, and holding times were acceptable
for the semivolatiles. Some problems were encountered with surrogate
recoveries and one chromatogram.
The estimated detection limits for the semivolatiles were approximately
twice the CRDL except for samples Q1460 (15 times CRDL), 1462 (666 times CRDL),
1466 (100 times CRDL), and 1467 (40 times CRDL). These samples were highly
diluted thus there is a higher than ususal probability of false negative
results.
The phenol-D5, 2-fluorophenol, and 2,4,6-tribromophenol surrogate spikes
in samples Q1452, 1452RE (reanalysis), 1453, 1453RE, 1456, 1460, 1462, 1466,
1467, and QO864 were not recovered from any sample with the exception of 2,4,6-
tribromophenol from sample Q1456 (only 8 percent recovery). Samples Q1460,
1462, 1466, and 1467 were diluted during sample preparation and the surrogates
were apparently diluted out. The nitrobenzene-D5, 2-fluorobiphenyl, and
terphenyl-D14 surrogates were also not recovered from those diluted samples.
Recovery of 2-fluorophenol from sample Q1471 was 40 percent which is below the
DQO of range 43 to 116 percent. Recovery of tcrphenyl-D14 from samples Q1455,
QO865, and 867 was 147, 155, and 196 percent, respectively, which is above the
DQO range of 33 to 141 percent.
The chromatography for sample Q1460 showed high levels of contamination
and the sample should have been cleaned up and reanalyzed.
According to the laboratory Form I's, sample Q1452 was originally
extracted on 11/25/86 and analyzed on 12/11/86. This sample was, again
according to the Form I's, re-extracted on 12/2/86 and reanalyzed on 12/10/86,
-------
"which was p-ior to the original analysis. The reason(s) for this were not
expla'o v Pc.sibly the dates were transposed buy the laboratory. The Case
Narratives, as well as the Form I's, indicate that a number of semivolatile
samples was re-extracted and reanalyzed but no original data was provided.
The semivolatile data are acceptable and the results should be considered
quantitative for all samples with several exceptions. All semivolatile results
for samples Q1460, 1462, 1466, and 1467 and semivolatile acid fraction results
for samples QO864, Q1452, 1453, and 1456 should be considered qualitative due
to increased probabilities of false negatives and the poor surrogate
recoveries. These samples were highly diluted resulting in raised detection
limits and increased probability of false negative results. The probability of
false negatives is acceptable for all other samples.
3.5 Pesticides
The initial and continuing calibrations, blanks, matrix spike/matrix spike
duplicates, surrogate spikes, and holding times for pesticides were acceptable.
Some of the pesticide chromatograms appear to contain non-pesticide or
unidentified peaks.
The estimated pesticide method detection limits were CRDL with the
exception of samples Q1460 (4 times CRDL), 1462 (20 times CRDL), and 1466 (10
times CRDL). There is a higher than ususal probability of false negative
results for sample Q1462 due to the high sample dilution.
The dibutylchlorendate surrogate compound was not recovered from sample
Q1462 due to the high sample dilution.
There were peaks in the pesticide chromatograms of samples Q1455 and QOS78
that fall within some of the HSL (hazardous substance list) retention time
windows. These samples should have been run on a confirmation column. Also,
many pesticide chromatograms had solvent peaks that did not return to baseline
until 3 to 5 minutes after elution. Early eluting pesticides, such as the
BHCs, may have been obscured. Many of the pesticide chromatograms contained
non-pesticide contamination. As in previous cases, there was contamination
present on chromatography from pack 07 (CompuChem Lab's designation of a
particular Gas Chromatography column and instrument) at approximately 17 to 18
minutes elution time. This was also present in the pesticide blanks.
The pesticides results should be considered qualitative with the exception
of the early eluting pesticides, such as the BHCs, which should be considered
unreliable. There is an enhanced probability of false negatives for BHCs in
all samples and for all pesticides in sample Q1462.
-------
Note.
(1) Blank contamination is judged to have the following affect on sample
"results for the contaminant only. All negative sample results and positive
Cample results greater than ten times the concentration of the highest blank
concentration (for the contaminant) should be considered quantitative unless
there are other data quality problems. All positive sample results greater
_ than five but less than ten times the concentration of the highest blank
concentration should be considered qualitative. All positive sample results
less than five times the highest blank concentration should be considered
unusable. The detection limit for the contaminant should be considered to be
raised to five times the level of the highest blank contamination. Other data
quality problems may further reduce the quality of these determinations.
(2) The comparative precision of field duplicate results is not used in the
- evaluation of sample results. It is not possible to determine the source of
this imprecision. This poor precision may be reflective of sample to sample
variation rather than actual sampling variations. Thus, field duplicate
precision is reported for informational purposes only.
