RE: Extension Request for UIC Permit No. WI0500328
Mallinckrodt LLC, Raleigh Pharmaceutical Plant
Raleigh,North Carolina. EPA ID No. NCD 042 091 975
Dear Mr. Goodrich:
On December 9, 2010, Mallinckrodt LLC (Mallinckrodt) submitted an Underground Injection
Control (UIC) Permit Application to the North Carolina Department of Environment and Natural
Resources (NCDENR), Division of Water Quality, Aquifer Protection Section (APS) to inject a
tracer dye (Fluorescein) into groundwater. The purpose of this work was to conduct several
single-well tracer tests to define potential groundwater velocity ranges within and outside a
geological feature below the Site that is acting as a preferential migration pathway for
groundwater impacted with the following constituents of potential concern: 1,2-dichlorethane;
1,2-dichloropropane; acetone; methyl isobutyl ketone; phenol; benzene; toluene; ethylbenzene;
xylenes; aniline; and nitrobenzene.
The referenced UIC Permit was issued on April 27, 2011, the tracer injection activities began on
May 16, 2011, and subsequent monitoring activities occurred until February 2012 to determine
whether fluorescein readings have returned to background levels. A Final Project Evaluation
Report for the referenced permit was submitted to NCDENR-APS on June 10, 2012, which noted
that fluorescein concentrations had not yet returned to background levels within two tracer f
injection wells: PP-1S (8.53 micrograms per liter [pg/L])and Bla(28.6 µg1L).
A second UIC Permit Application was submitted to the NCDENR-APS on March 23, 2012 to
pilot test an in situ reactive zone (IRZ) remedial strategy for the Site. UIC Permit No.
W10500499 was subsequently issued on July 6, 2012 for the IRZ testing activities. The
monitoring program for this permit also included the testing for fluorescein within monitor wells
PP-IS and Bla to facilitate the completion of UIC Permit No. W10500328. However, the
effective end dates for UIC Permit Nos. WI0500328 and WI0500499 were March 31, 2013 and
June 30, 2014, respectively. Therefore, in accordance with email correspondences between Mr.
Donald Malone, ARCADIS, and yourself on March 26th and April 4, 2013, Mallinckrodt
respectfully requests NCDENR-APS to extend the termination date of UIC Permit No.
WI0500328 until June 30, 2014 to correspond with the end date of UIC Permit No. W10500499.

To UIC Program Staff:
Mallinckrodt Inc. is pleased to submit this Fluorescein Tracer Test UIC Permit Application(Type 5T—
Tracer Injection Well)for our Pharmaceutical Plant located in Raleigh,North Carolina. The purpose of
this work is to conduct several single-well tracer tests to define the potential groundwater velocities
within and outside of a geologic feature below the site that is potentially acting as a preferential migration

Single-well Tracer Tests
UIC Permit Application
ARCADIS Type 5T—Tracer Injection
1. Introduction
Mallinckrodt, Inc. (Mallinckrodt) retained ARCADIS U.S., Inc. (ARCADIS) to prepare
this Underground Injection Control (UIC) permit application to perform several single-
well tracer tests to quantify groundwater velocity below their Pharmaceutical Plant, in
Raleigh, North Carolina (the Site) (Figure 1). Mallinckrodt is in the process of
developing corrective action alternatives for the Site as directed within their Hazardous
Waste Management Permit issued by the North Carolina Department of Environment
and Natural Resources (NCDENR), Division of Solid Waste Management(as revised
on August 1, 2008). The NCDENR has been delegated by the U.S. Environmental
Protection Agency (USEPA) to run its own Hazardous Waste Management Program as
required by the Resource Conservation and Recovery Act (RCRA). The Site carries
the Hazardous Waste Facility EPA ID No. NCD 042 091 975.
ARCADIS (2008) developed an Interim Measures Work Plan (IM WP) in November
2008 to assist within the selection and testing of remedial strategy alternatives for the
Site. The first task within the IM WP included electrical resistivity (ER) testing to map
potential subsurface high-permeability zones that could be creating the very long and
narrow plumes of 1,2-dichloroethane (1,2-DCA), 1,2-dichloropropane (1,2-DCP), and
aniline within the surficial aquifer. ARCADIS installed three initial ER transects
(Figure 2) at the Site during the week of May 24, 2010, which identified several large
conductive features in all three ER pseudo sections. These features are likely relict
structures of the interfacial contact between the Rolesvifle Batholith and the Raleigh
Gneiss, due to varying degree of weathering along the contact boundary. There is a
strong suggestion that the conductive anomalies observed within the ER
pseudosections are preferential flow paths and potentially are acting as a groundwater
conduit(s) across the Site. A copy of the ARCADIS(2010) report titled Two-
Dimensional Resistivity and Magnetic Geophysical Investigation is included in
Appendix A.
Two additional ER survey lines were installed and tested during the week of November
5, 2010, which were located immediately north of the central manufacturing area near
the former BQ Pond and south of Durant Road. Final results from these additional
surveys are not yet available; however, preliminary results indicate the potential
presence of similar conductive features as were identified in the prior surveys_
Therefore, a very long narrow high conductivity zone exists below the facility that likely
extends several miles, or more, north and south of the facility.

Recommendations within the IM WP also included the evaluation of in-situ chemical
oxidation (ISCO), enhanced reductive dechlorination (ERD)and/or enhanced aerobic
biodegradation (EAB) as potential corrective measure alternatives for the Site.
However, ISCO was determined to not be economically feasible at the time but may be
considered for future studies as part of the Facility's Corrective Measures Study (CMS)
Work Plan. ERD targets chlorinated constituents in groundwater such as 1,2-DCA and
1,2-DCP. EAB targets aniline, nitrobenzene, benzene, toluene, and xylenes. The
primary constituents of potential concern (COPCs) for this tracer study are defined as
1,2-DCA; 1,2-DCP, and aniline.
ARCADIS plans to conduct single-well tracer tests to define the potential groundwater
velocities within and outside of the geologic feature(s) near the primary sources of
contamination. Mapping the groundwater velocities in different areas of the site will ---
provide ARCADIS with the ability to define the potential corrective measure alternatives
for the site ARCADIS will use the data from ER transects to select the locations and
screen intervals for multi-purpose monitor wells, which will be used for the tracer
injections, as well as other purposes.
Tracer testing will likely be performed in two phases as shown on Figure 3. Phase I
tracer testing will possibly be performed in the vicinity and downgradient of the former
Fire Training Area, based on the results of ER Survey performed during the week of
May 24, 2010 (Appendix A). The Phase II tracer testing work (Figure 3)will be based
on the second ER survey performed at the Site on November 5th and 6`h, 2010 in the
central manufacturing area Even though the results from this second ER survey are
not yet available; the preliminary results suggest that similar linear subsurface geologic
features exist below the central manufacturing area. This UIC permit application is
intended to present the proposed tracer testing activities for both Phase I and Phase Il
tracer testing activities.

B. INCIDENT DESCRIPTION
1. Describe the source of the contamination.
The purpose of this UIC permit application is associated with the
development of corrective measure alternatives for groundwater impacts
below the Site resulting from historical chemical processing and waste
management practices (not from any recent chemical releases to the
environment). The Mallinckrodt facility began production in 1966 of gallic
and tannic acids using methyl isobutyl ketone to extract humic substances
from sumac leaves. Although operations were generally conducted in
accordance with environmental regulations in effect at the time, past

ARCADIS Type 5T—Tracer Injection
practices have resulted in groundwater contamination beneath the site. One
cause of the groundwater contamination is thought to be releases over time
from manufacturing areas and the wastewater treatment system.
During the manufacturing of gallic and tannic acids the wastewater treatment
system included five tannin pits, approximately 10 feet deep and 100 to 150
feet diameter constructed with silty clay. The pits were used to stabilize the
residual sludge from the extraction process(Figure 3). The production of
gallic and tannic acids ended in 1973. The former tannin pits are expected to
be the source of 1,2-DCA; 1,2-DCA; MIBK; acetone; BEX; and toluene in
groundwater.
Production of para-aminophenol (PAP) and acetyl para-aminophenol
(APAP), also known as acetaminophen, began in 1972. Historically,
wastewaters from PAP and APAP manufacturing were treated on Site in
aerobic lagoons(BQ Pond and Basins 1 & 2). The BQ Pond and Basins
were located to the west and southwest, respectively, of the Flush Water
Pond. In the early 1990s, the use of the BQ Pond and Basins were phased
out and a wastewater treatment plant was built. The wastewater treatment
lagoons were expected to be a source of aniline, toluene, MEK, methylene
chloride phenol, and nitrobenzene.
The main production areas are expected to be the primary source of aniline
and nitrobenzene in groundwater(Figure 3).

3. Site Description
3.1 Site History
3.1_1 Site Background
The Site is located just west of US Highway 1 (Capital Boulevard) at the northern limits
of the City of Raleigh (Figure 1). The Site encompasses 613 acres, with
approximately 320 acres west of the CSX Railroad line that bisects the property in a
north-south direction. Most of the area west of the railroad line is in permanent
pasture, irrigated using wastewater residuals from the onsite wastewater treatment
plant as regulated by the Land Application of Wastewater Residuals Permit No.
WQ0005537. East of the railroad line, the manufacturing facility and wastewater
treatment plant are located on approximately 35 acres. All of the SWMUs and the area
of concern are located to the east of the railroad line with associated groundwater
impacts located both on and off the Site property. The flush water pond collects most
of the surface water drainage at the Site, and is located at the northern edge of the
property. Two adjacent properties are also owned by Mallinckrodt: the Medical
Imaging Plant(MIP)at 8800 Durant Road, and a 32.12 acre property south of Durant
Road (Figure 3).
The Site's central manufacturing area is composed of three main buildings and
additional support facilities These include administration buildings, a wastewater
treatment plant, a maintenance shop, cooling tower and boiler system. The Site
produces two products, Para-aminophenol (PAP) and acetyl para-aminophenol
(APAP), also known as acetaminophen.
3.1.2 Origin of Contamination
In 1966, Mallinckrodt initiated construction of the Site to produce gallic and tannic
acids. The location was previously occupied by farmland. The process to manufacture
gallic and tannic acids used methyl isobutyl ketone (MIBK) as the primary solvent to
extract the humic substances from sumac leaves. Tannin pits were used to stabilize
the residual sludge from the process, five pits (approximately 10 feet deep, 100-150
feet diameter) were used at the Site. Production of APAP and PAP began in 1972,
and production of gallic and tannic acids ended in 1973.
The current PAP manufacturing process uses nitrobenzene, hydrogen, sulfuric acid
and ammonia to generate PAP, aniline, and the byproduct ammonium sulfate. APAP

manufacturing uses PAP and acetic anhydride to produce APAP and acetic acid.
Wastewater produced during these processes is treated onsite; historically, it was
treated using a series of aerobic lagoons (BQ Pond and Basins 1 & 2) In the early
1990s, use of the BQ Pond and Basins 1 &2 was phased out when aboveground
tanks for the wastewater treatment plant were built.
3.2 Hydrogeologic Description
3.2.1 Site Geology
The Site overlies gneissic rocks of the Raleigh Gneiss and granitic rocks of the
Rolesville Batholith; the boundary between the two is gradational, and has been
mapped as a southwest trending line passing through the central manufacturing area.
Strike and dip data are fully described in the Phase II RFI (Solutions-IES 2005).
Geology and hydrogeology have been explored during installation of numerous
permanent and temporary monitor wells, piezometers, and soil borings. There are
records for 113 monitor wells, recovery wells and piezometers installed on the
property, 105 of which are still in place (Table 1). Figure 2 shows the proposed
locations of borings to be installed in Phase I, of which two of the borings will be
converted to multi-purpose monitor wells and uses for monitoring, hydraulic testing,
and tracer injections. Figure 3 contains an overal# Site layout with the locations of
existing monitor wells and the areas for the Phase I and Phase II tracer testing
activities.
Surficial soils at the Site, generally present to a depth of 20 to 35 feet below ground
surface (bgs), consist mostly of silty sand, sandy silt and fine to medium sand with
occasional clay. Figure 4 depicts a map showing the location of a site-wide geologic
cross-sections. Figure 5 shows the north-south cross-section. Figures 6 and 7 show
west-east cross-sections Soils in the southern portion of the Site (near Durant Road)
tend to be sandier than soils in the northern portion of the Site. Below the surficial soil,
partially weathered rock (PWR) is present This material consists of soils with original
foliation and rock textures (saprolite), and contains fine to coarse fragments of
weathered granite, feldspar and mica grains. Weathered rock or bedrock, more
resistant than the PWR, is found at depths ranging from 39 to 100 feet bgs- Fractures
are mostly oriented to the northeast and aligned along foliation in the gneissic
structure. Most fractures dip to the southeast(Geraghty & Miller 1994)
The results from the ER surveys suggest that a linear partially weathered, higher
permeability zone is present below the Site that trends in a north-south orientation

(Appendix A). This large conductive feature is present in all three pseudosections,
and is approximately the same size and depth in each line. Based on literature
reviews and a field reconnaissance of stream contacts in the vicinity of the Site,
ARCADIS believes the large conductive features in the ER pseudo sections are a
contact margin between the Rolesville Batholith and the Raleigh Gneiss that has highly
variable weathering. ARCADIS has developed a detailed scope of work, including the
single-well tracer testing proposed herein, to evaluate the significance of these
geologic features to transport chemical constituents within apparent preferential
migration pathways.
3.2.2 Site Hydrogeology
Groundwater at the Site exists in the unconsolidated water table unit and in the
fractured bedrock unit. The unconsolidated water table unit has been separated into
two zones: a shallow zone and a deep zone, which are hydraulically connected. The
upper unconsolidated aquifer(shallow zone) is composed of residual soils and
saprolite, while the lower unconsolidated aquifer(deep zone) includes saprolite and
PWR. The bedrock water unit includes both highly fractured/weathered rock and less
weathered, competent rock. Consistent with the Piedmont hydrogeology, the PWR
transition zone between the unconsolidated aquifer and bedrock aquifer is a primary
groundwater flow conduit beneath the Site.
The water table surfaces in the upper and lower unconsolidated aquifer zones
generally mimic the topography at the Site. Table 2 includes depth-to-water and
subsequent potentiometric water elevations for 55 Site monitor wells gauged in June
2008. Figures 8 and 9 show the groundwater potentiometric surface maps for the
shallow and deep aquifer zones, respectively. Groundwater below the Site flows from
the centrally located east-west trending ridge towards tributaries of the Neuse River to
the north and a tributary of Perry Creek to the south. Groundwater flow beneath the
Site is influenced by surface water impoundments and pumping wells_ Overall, there is
a groundwater divide at the topographic ridge beneath the Site that traverses the
central manufacturing area between Capital Boulevard and the CSX Railroad. This
mound is centered near wells MA-3D and MW-3, with radial flow primarily to the north
and south. Groundwater flow in the bedrock aquifer is interpreted to be similar to the
flow directions in the overburden unit(Solutions-IES 2006). In addition, the
groundwater flow direction in bedrock is influenced by foliation and fracture patterns.
The influence of pumping wells PP-8, PP-9 and PP-16, located near Durant Road,
create an elliptical radius of influence extending up to 390 feet on the long axis (parallel

to Durant Road) under pumping conditions (Solutions-IES 2005). Surface water at the
Site, including the Flushwater Pond, a stormwater retention pond, and tributary
streams on both the north and south portions of the Site, interact with groundwater as
both discharge and recharge features. The Flushwater Pond likely accepts discharge
from the aquifer at the southern end, and recharges groundwater at the northern end.
Average horizontal hydraulic gradients vary across the Site, ranging from 0.0131 feet
of hydraulic head per foot(ft/ft) in the southern direction to 0.0195 ft/ft in the northern
direction in June 2008. Vertical hydraulic gradients were calculated for seven well
clusters across the Site. All clusters exhibited slightly downward vertical hydraulic
gradients. Vertical hydraulic gradients ranged from 0.001 ft/ft at monitor well pair
GW-4S/D to 0.0196 ft/ft in monitor well pair PP-3S/D. The results are consistent with
the presence of a single interconnected hydraulic system at the Site, with no major
boundaries preventing vertical migration of groundwater between the overburden and
bedrock units.
Hydraulic conductivity values have been estimated at the Site using slug tests,
pumping tests and a recovery test(Solutions-IES 2005). The estimates have varied
widely across the Site, from 0.05 to 18.6 feet per day. A north-south band of hydraulic
conductivity values greater than the Site average is present across the Site in both the
shallow and deep overburden zones, based on slug test data. This zone parallels the
foliation and rock fractures measured at the Site, and the elliptical cone of depression
at the Durant Road recovery wells.
Groundwater velocity estimates calculated using gradient data from June 2008 and
hydraulic conductivities from the Phase II RFI indicate groundwater velocities range
from less than 10 ft/yr to greater than 300 ft/yr in both the shallow and deep portions of
the overburden water bearing unit. Transmissivity in the bedrock zone is estimated to
be approximately an order of magnitude lower than the transition zone and overburden
soil (Solutions-IES 2006).
During the June 2008 sampling event, average depth to water was 19.02 feet (ft) for 54
wells gauged during the event. Sampling of 29 wells was also conducted. The
historical data, including June 2008, is included in Table 3. Constituents of concern at
the Site include 1,2-DCA, 1-2-DCP, BTEX, and aniline. All constituents are present in
both the shallow and deep aquifer zones. Figures 10 and 11 depict the BTEX plumes
in the shallow and deep aquifer zones, respectively. Figures 12 and 13 depict the 1,2-
DCA and 1,2-DCP plumes in the shallow and deep aquifer zones, respectively.

4. Single-well Tracer Tests and Fluorescein Injections
4.1 Injection Fluid Composition
Fluorescein, is an organic compound which has been widely used as a fluorescent
tracer for a variety of applications. Fluorescein, C20H1005.2 NA, is generally provided as
an orange-red powder. A Material Safety Data Sheet(MSDS) for fluorescein is
included in Appendix B. Fluorescein dye(as a tracer) is on the list of NCDENR
approved injectants. A combination of municipal water and/or water from the tracer
test wells will be used to create the dilute tracer injectate. Fluorescein is completely
soluble in water.
4.2 Injection Rationale
The objective of the fluorescein injection will be to measure the flux of groundwater
through each tracer test well. Heterogeneity can cause slower mean velocity in some
fraction of the lower permeability pores while faster mean velocity may occur in other
pores. Single-well tracer tests allow for understanding and quantifying the groundwater
flux variations in wells within and outside the geologic feature that are causing the
unique configuration of the dissolved chemical plumes at the Site. Once groundwater
flux variation is understood, this along with information from electrical resistivity
surveys, will allow for remedial strategies to be selected and implemented at the Site.
A fluorescein concentration of approximately 40 mg/L (or between 30 and 50 mglL) will
be used for the injection. Injection concentrations are selected at more than two orders
of magnitude above the visual threshold, or 0,1 mg/L for fluorescein, and more than
five orders of magnitude above the typical analytical detection limit, or less than 0.001
mg/L. This gives the concentration range of 30 to 50 mg/L
Fluorescein is an inert and stable compound and is considered to be only slightly
sorbed by clays, dissolved organics, charged solvent species, and/or organic and
inorganic particulates (Field et al. 1995). Fluorescein is highly soluble in water, has a
low oxidation reduction potential, and has a relatively neutral pH Fluorescein does
not produce any hazardous short term degradation products and its products of
degradation are non-toxic.

Type 5T—Tracer Injection
4.3 Injection Procedure and Equipment
A diagram of a washout tracer test is presented in Appendix C. The water column
from the tracer test well will be removed and the extracted water will be mixed above
ground with fluorescein dye to an approximate concentration of 40 mg/L and injected
into the well. Alternatively, municipal water will be used to create the tracer solution
and injected into the well.
The Phase I multi-purpose monitor wells (Bla and B3a) and Phase II multi-purpose
monitor wells (B4a and B5a)will be 2-inch diameter wells with 0.010-inch slot stainless
well screen and casing. One tracer test per well is currently planned for six wells in
Phase I and six wells in Phase II. See Section 2.4, paragraph C.3. (above) (Figure 3).
PP-8 currently is an operating pumping system as part of a hydraulic barrier on the
north side of Durant Road. Therefore, the pumping system will not be shut off for more
than a 3-day period to conduct the injection and post-injection monitoring. The
Monitoring period for the other tracer test wells for up to a 6-week period. Slug tests
will be conducted on all twelve (12)wells(including both Phase I and II) prior to
injection.
The tracer injections may require—5 minutes up to 2 hours to complete at each
location. This application plans for up to 24 hours for the injections (in the event that a
second injection is necessary to maintain tracer concentrations). The injection solution
will be gravity fed and no more than 5 psi will be applied to the tracer test wells.
Fluorescein will be mixed in a polyethylene tank set for recirculation. Once fully mixed,
the solution will be gravity-fed into each tracer test well_ Flow rates will be controlled
using a gate valve. Pressure will be controlled by injection and extraction to keep depth
to water constant. Total injection volume will be controlled through injection and
extraction and depth to water measurements. Conceptual models of a groundwater
tracer concentration-distance profile and a tracer breakthrough curve can be seen in
Appendix C
The first round of injections will occur within 2 month of receiving approval to proceed,
after the four new tracer test wells have been installed. Post-injection monitoring is
described in the following section.

5. Monitoring Plan
A total of six (6) wells will be used for the single-well tracer tests and fluorescein
injection for both the Phase I and II tracer tests. The proposed tracer test wells for both
Phase I and II tracer tests are discussed in Section 2.4, paragraph C_3. (above). After
installation of the new multi-purpose monitor wells for Phase I (B1a and B3a) and
Phase II (B4a and B5a), water samples will be collected and analyzed for volatile
organic compounds(VOCs) by USEPA Method 8260B and semi-volatile organic
compounds (SVOCs) by USEPA Method 8270C. Biogeochemical parameters will be
measured using a field multi-meter. Slug tests will be conducted on each well to
establish hydraulic conductivity values for each well.
Tracer concentration will be measured in the tracer test wells over a 6-week period for
all wells except recovery well PP-8. As discussed in Section 4.3, recovery well PP-8
currently is an operating pumping system as part of a hydraulic barrier on the north
side of Durant Road Therefore, the pumping system will not be shut off for more than
a 3-day period to conduct the injection and post-injection monitoring. The assumed
sample intervals will be on Day 0 (immediately after injection to establish a baseline
dye concentration), and followed by Days 1, 2, 3, 7, 14, 28, and 42, for a total of 6
weeks, The sampling frequency will be dynamic as the test progresses and may need
to be adjusted based on the rate of decay of the tracer observed in the monitoring
wells. Samples will be collected from the wells issuing temporary dedicated bailers and
_ shipped to an off-site laboratory for quantification of the tracer concentrations Samples
will be collected in laboratory-provided glass or plastic bottles, which will be compatible
with the sample matrix (groundwater samples). ARCADIS will then use the laboratory
analytical results to calculate actual groundwater flux by correlating concentration
decay of the tracer over time using empirical calculations.

6. Well Data
Table 1 contains monitor well construction details for all 105 existing Site monitor
wells, including well use, total depth, screen interval, and top of casing elevation. The
locations of the wells are shown in Figures 2 and 3, with the exception of the multi-
purpose monitor wells B4a and B5a proposed in Phase II. The current monitor well
network will be sufficient for the injection; however four(4) tracer test wells (multi-
purpose wells)will be installed during the Phase I and Phase I tracer tests. The
proposed construction details for four multi-purpose monitor wells B1 a, B3a, B4a, and
B5a are shown on Figure 16.
Previously known or suspected water supply wells exist along Durant Road and U.S.
Hwy 1 (Capital Boulevard) adjacent to the Mallinckrodt facility, and are within a 1,500-
foot buffer from the facility's property line. However, several of these properties were
converted to a public water supply during the last 8 years. Most of the referenced
properties are >Vs mile (>1,320 feet)from the proposed tracer injection points.

which included a 2002 Well Survey are included in Appendix D and present details
regarding the construction and location of known or previously suspected water supply
wells. The closest injection point is the property located at monitor well PZ-4, which is
located approximately 1,000 feet due east of monitor well PZ-4. The primary
groundwater flow direction from the Site is to the south.
Environmental investigations have occurred at the site from 1989 to present that have
defined the primary groundwater flow directions and fully characterized the vertical and
horizontal extents of soil and groundwater impacts at the facility. Mallinckrodt's
consultants have installed and sampled sentinel wells along the property boundary to
monitor the potential for impacted groundwater to migrate toward these potable water
supplies. Based on the results of these investigations, the groundwater impacts on the
Mallinckrodt property do not currently pose a threat to these drinking water sources.
The tracer injections are being proposed to assist with the development of corrective
measure alternatives for these groundwater impacts; which will reduce chemical
concentrations and promote significant improvements to groundwater quality. The
proposed loading rates of the tracer compounds are relatively insignificant as
compared to the current chemical impacts in groundwater, and therefore, by inference
should not cause any additional threat to these potable water sources. Additional
information can be provided to NCDENR at your request.

Executive Summary
ARCADIS U.S., Inc. (ARCADIS), was retained by Mallinckrodt Inc. (Mallinckrodt)to
perform three 2-dimensional electrical resistivity surveys and a single magnetometry
survey at Mallinckrodt's Raleigh Pharmaceutical Plant located at 8801 Capital
Boulevard in Raleigh, North Carolina (Site). ARCADIS conducted the geophysical
survey at the Site during the week of May 24, 2010. The primary objective of the
survey was to identify the location, depth, anti/or orientation of the subsurface
geological feature(s)that are causing the unique migration patterns for the Site
constituents dissolved in groundwater The proposed geophysical surveys included a
magnetometry survey and an electrical resistivity survey. However, the magnetometry
survey was conducted first to attempt to confirm whether a diabase dike could be
present. Three survey lines were conducted at the Site along transacts to the long and
narrow dissolved-phase groundwater plume to evaluate the potential for and to
determine the location of subsurface geological conditions that are creating a
preferential migration pathway below the Site.
Based on the results of this work, ARCADIS has determined that several large
preferential migration pathways exist below the Site. Consistent with our proposal
dated January 12, 2010, ARCADIS has developed a detailed scope of work to evaluate
the significance of the geologic features below the Site to transport chemical
constituents farther off site. ARCADIS is in the process of refining the scope of work
presented within our proposal based on the results of the surveys conducted herein.
Refinements to that scope of work will be presented to Mallinckrodt in the near future.
We plan to schedule a conference call with during the week of July 26, 2010, to
present the next phase of investigations

1. Introduction
A geophysical investigation was conducted the week of May 24, 2010, at the
Mallinckrodt Inc. (Mallinckrodt) Pharmaceutical Plant in Raleigh, North Carolina (Site).
The Site layout, location of monitoring wells, and geophysical survey lines for the
property are shown on Figure 1. The primary objective of the survey was to use
electrical resistivity imaging and magnetometry to determine the presence of linear
geologic features at the Site that may be controlling groundwater by acting as
preferential flow paths. The direct current electrical resistivity technique was chosen
for its ability to discriminate various lithologic units and saturated versus unsaturated
material. The magnetic survey technique was included for its ability to differentiate
earth materials with various compositions (granite/schist and saturated/unsaturated).
Three geophysical transects(Lines 1, 2, and 3)totaling approximately 2,725 linear feet
were completed at the Site. Line 1 was oriented east-west on the Mallinckrodt
property. The origin of the line was the electrical transmission line to the west of the
property. Linel went through the wooded area, crossed a gravel service road
connecting the Site to the Mallinckrodt Imaging Plant located at 8800 Durant Road,
and terminated just north of the Imaging Plant's parking lot(Figure 1). Line 2 was
oriented roughly northwest to southeast along the northern edge of Durant Road. The
origin of Line 2 was at the base of the electrical transmission line to the west of the
property. The line ran roughly parallel to Durant Road and terminated at the edge of
the Imaging Plant's entrance driveway. Line 3 was oriented east-west on the Site
property, immediately north of the Imaging Plant's property. The origin of Line 3 was
beneath the electrical transmission line at the west of the property. Line 3 ran roughly
flat until approximately 500 feet down the line where it rose in elevation to the parking
area for the contractor storage sheds. Line 3 terminated at the drainage ditch adjacent
to the western edge of the warehouse parking lot. All lines are shown on Figure 1.
The initial plan was to perform electrical resistivity imaging along each transect and to
collect magnetic data along the same lines. However, the density of the wooded area
through which Line 1 ran was too high for the magnetic equipment to be used. Also,
the area along Line 3 was being used as a lay-down yard and was covered with
surface metal piping, vessels, vehicles, etc. These surface objects would have
significantly affected the magnetic response. Therefore, magnetic data were only
collected along Line 2 because this transect was unobstructed and free of surface
metal objects.

and recommendations.
2. Methodology
2.1 Electrical Resistivity Technique
The electrical resistivity method involves the measurement of the apparent resistivity of
subsurface soils and rock as a function of depth and/or position. The resistivity of soils
and rock is a complicated function of porosity, permeability, ionic content of the pore
fluids, and degree of clay mineralization.
During a resistivity survey, current is injected into the earth through a pair of current
electrodes and the potential difference(voltage) is measured between one or more
pairs of potential electrodes. The current and potential electrodes are generally
arranged in a linear fashion with the geometry of the current and potential electrodes
being referred to as an array. Common arrays include the Wenner array,
Schlumberger array (normal and inverse), and the dipole-dipole array. The latter two
array types were used during this investigation. The apparent resistivity is the bulk
average resistivity of all soils and rock influencing the current. It is calculated by
dividing the measured potential difference by the input current and multiplying by a
geometric factor specific to the array being used and electrode spacing.
The geometric arrangement or array of the electrodes can be classified according to
the shape of the electrical field that is being measured. In general, there are three
basic families of arrays that describe either a parallel electric field, the field about a
point electrode, or a dipolar electric field. The ratio of the signal voltage to the external
disturbing noise voltage (background electrical field) is important when choosing an
array type. Generally, the Wenner and Schlumberger(normal and inverse)provide the
highest signal to noise ratio and are best for determining geologic changes. The
Wenner array is more sensitive to vertical changes in resistivity (i.e., layered geology)
than other arrays, at the expense of lower lateral resolution, whereas the Inverse
Schiumberger array has better lateral resolution than the Wenner array at the expense
of signal strength. The dipole-dipole and dipole-gradient arrays produce high
resolution for both lateral and vertical features but have limited depth penetration
unless very long electrode lines are used. Both the dipole-dipole and inverse
Schlumberger arrays were used in this study.

2.2 Magnetic Survey Technique
Magnetic surveying (also magnetometry) is one of the most popular methods of the
several geophysical techniques developed for or adapted to the need for a rapid
nondestructive evaluation of environmental and archaeological sites.
In magnetometry, the strength of the earth's magnetic field is measured a few
centimeters above the surface of a site using very sensitive magnetometers. The
earth's magnetic field in mid-northern latitudes is roughly 50,000 nanotesla (nT), while
the sensitivity of modern instruments can be 0.01 nT. The most widely used
instrument is the proton precession magnetometer, although the fluxgate gradiometer,
which can filter out regional magnetic variations and focus on shallow targets with
much higher resolution, is a superior instrument. A gradiometer consists of two
magnetometers attached to a rod of known distance. As data are collected from both
sensors, a gradient magnetic measurement can be calculated, which has significantly
higher resolution for shallow objects and accounts for temporal changes in the earth's
magnetic field that occur during the survey. A gradiometer was used for this study.
Data acquisition involves holding the rod with the two magnetometers attached in front
of the body and walking a defined transect. Data are collected several times a second
and are linked to a streaming global positioning system (GPS) unit for georeferencing
the results.
Magnetic measurements are used for geologic mapping by detecting contrasts in the
magnetic susceptibility of soil and rock. Geologic strata with high remnant magnetism
(chiefly caused by the presence of hematite, the most common magnetic mineral)are
more magnetically susceptible, which causes a local variation in the earth's magnetic
field. Displacement or disruption of a uniformly magnetic soil or rock layer can also
create local magnetic variations that can be detected by a magnetometer. A feature
such as a fault or fracture, which causes a disruption of the measurement along the
transect, can be detected by plotting the magnetic response of the instrument as a
function of distance. If a single magnetometer were used, the presence of a fault or
fracture would appear as a drop in magnetic susceptibility. When using a gradiometer,
the results are represented as the change(in nT)of the magnetic susceptibility as a
function of distance. Buried metal objects and other metallic infrastructure also have
magnetic susceptibility and generally are observed as localized spikes in the
measurements.

3. Survey Data Acquisition
Two-dimensional (2-D)electrical resistivity data were acquired along the three survey
lines during the week of May 24, 2010. The resistivity equipment used during this
investigation consisted of an Advanced Geosciences, Inc. (Austin, Texas),
SuperSting- R8/IP memory earth resistivity system with a 112-electrode switch box,
electrode cables with a 3-meter connector spacing, and stainless steel electrodes. The
geophysical transects were established based on historical data from the Site, the
current understanding of previously defined plume dimension and orientation, and
access considering Site infrastructure and obstructions.
Upon completion of data acquisition, initial and terminal electrode locations for each
line as well as electrode locations in areas with significant topographic changes were
marked with flags and general elevation changes recorded These data can be used
to establish elevation changes along the transects so that the geophysical data could
be corrected for terrain during processing. The terrain change along the transects was
minimal for Lines 1 and 2 so no topographic correction was needed. Terrain correction
was made for Line 3.
Resistivity data were stored in the internal memory of the SuperSting R8/IP and
downloaded to a laptop computer upon completion of each survey. Field data files
were assigned a name that included Line name and array type. Preliminary modeling
of the field data was conducted in the field in order to optimize the subsequent data
collection. The final data processing was completed in the office at a later date.
The magnetic survey was conducted using a Geometrics G858 Gradiometer with
cesium vapor sensors. The unit is mounted to the body and data are collected as the
transect is walked. All data (magnetic and GPS spatial data)were stored in the
internal memory of the unit and retrieved after each survey.
4. Electrical Resistivity Survey Data Processing
The 2-D resistivity data were processed using the program Earthimager 2D v2. 3.5,
Build 635 by Advanced Geosciences, Inc. (Lagmanson and Yang 2002). Preliminary
data processing was conducted in the field and the final data processing was
completed in the office. The resistivity acquired using the dipole-dipole and Inverse
Schlurnberger arrays were merged and modeled as a single dataset. Prior to data
modeling, a number of preprocessing steps were completed, including removal of
voltage spikes, poor voltage decay, and low data-quality readings from the raw field

data. In all cases, an acceptable amount of data was removed, leaving sufficient data
for accurate earth model generation.
Quality assurance checks were performed on all datasets to determine if low-quality
(noisy)data were uniformly distributed across the data or localized to specific areas.
This analysis was done using scatter plots shown in Appendix A. Points shown as
black are removed from the dataset prior to inversion. Therefore, areas with large
groupings of black points have lower confidence in interpretation. In general, all three
resistivity survey lines had significant data removal in areas where the survey line
crossed underground utilities. This is common and is due to the metallic nature of
these utility lines.
Resistivity data were processed using a damped least-squares or smooth model
inversion using a finite element mesh with surface topography to generate a 2-D model
of resistivity versus depth/elevation. The electrode locations marked in the field were
assumed to be slope distance, rather than horizontal distance. The starting model for
the inversion consisted of either a variable resistivity model based on the apparent
resistivity distribution or a constant resistivity model based on the apparent model. A
forward modeling routine was used to generate the theoretical resistivity data for the
starting model. The theoretical resistivity data were compared to the field data and an
inverse modeling routine was used to update the resistivity model over a series of
iterations until acceptable root mean square(RMS)and/or L2 norm errors were
obtained. The RMS error measurement takes into account all data points in the
dataset. Therefore, any erroneous data point outliers that are several orders of
magnitude off from the other data points will trigger a large and incorrect RMS error.
The L2 norm error metric is a weighted measure of the predicted data set compared to
the observed data set and is not affected by a small number of data point outliers.
Magnetic susceptibility data were processed using the MagMap 2000 software. This
software allows significant manipulation of the data through filtering and smoothing
algorithms when excessive noise is present in the dataset. The magnetic data
collected at the Site were high quality and did not require any post-processing. The
complete dataset contains the measurements from each of the two sensors(top and
bottom)as well as a calculated vertical gradient measurement. Only the vertical
gradient measurement is included in the report figures. However, the complete data
are included as Appendix B.

Output of the resistivity model is depicted graphically as pseudosections using the
Earth Imager software. Output of the magnetic survey is depicted as a 2-D line graph
using Microsoft Excel software.
5. Interpretation
The inverted resistivity models for Lines 1, 2, and 3 are presented in Figures 2, 3, and
4, respectively. The pseudosection represents the inverted apparent resistivity data in
units of Ohm-meters (f2-m). In all pseudosections, the x-axis represents feet along the
2-D transect from the starting point of the survey line. The y-axis is the depth in feet
from the ground surface. Depth is theoretically calculated using an assumed current
path and is therefore not exact. However, experience has shown that the error
associated with the depth calculation is generally±3 to 5 feet and therefore is not
significant considering the overall scale of this project Site.
Based on the response of all data collected at the Site, the resistivity pseudosection
scales ranged from 2 0-m to 100,000 0-m for Lines 1 and 2 and from 5 0-m to
40,000 0-m for Line 3. All apparent resistivity values are relative within each dataset.
Comparison of absolute values from one line to another is generally not appropriate.
The lateral and bottom edges of the resistivity pseudosections should be interpreted
with lower confidence in general, due to edge effects associated with the point
interpolation methods used in the visualization software. Pseudosections are a
distribution of single points of apparent resistivity and are visualized graphically through
interpolation between the known points employing a group of numerical techniques
collectively known as Kriging. Because Kriging assumes a deterministic trend in the
surface based on statistical variation, it and all interpolation methods cannot accurately
account for the sudden lack of data associated with the edge of a dataset. This error
generally manifests as projection of nearby features to the edge, making them appear
to be more spatially extensive. Therefore, large anomalies near the pseudosection
edges may not be accurate or real. The anomalies of importance for this Site are all
within the center of the pseudosections and are therefore of high confidence. A
possible exception to this statement is the anomaly numbered L3-C within Survey
Line 3, which is located on the far eastern (right)edge of the pseudosection (Figure 4).
5.1 Survey Line 1 -Electrical Resistivity Results
The inverted resistivity model for data collected along Survey Line 1 is presented on
Figure 2. A quality assurance check of the dataset indicated high quality data for the

majority of the line. The data removal was uniform throughout the dataset except for
the area approximately 700 feet down the line, which corresponds with the crossing of
an underground utility conduit. The primary geologic features apparent in the
pseudosection are four highly conductive areas (labeled L1-A through L1-0)and a
large tabular highly resistive zone spanning from approximately 500 to 900 feet along
the line, generally at a depth range from 75 to 240 feet below land surface (bis). The
conductive areas are located from 30 to 75 feet bls. All four conductive features are
consistent with the response of material with higher water saturation than the
surrounding material. These areas are likely more porous and therefore more
saturated. Based on experience, these features are suggestive of preferential flow
paths. The large feature labeled as L1-B may appear larger than it actually is due to
interference from the underground steam/water utility line that crosses the line at that
point. The groundwater surface in this area of the Site is typically located at
approximately 25 feet bls. Therefore, the depths of these conductive features are
consistent with the anticipated depth to groundwater.
5.2 Survey Line 2
5.2.1 Electrical Resistivity Results
The inverted resistivity model for data collected along Survey Line 2 is presented in the
top panel on Figure 3. A quality assurance check of the dataset indicated high quality
data for the majority of the line. The data removal was uniform throughout the dataset.
The primary geologic features apparent in the pseudosection are five highly conductive
areas (labeled L2-A through L2-E) and a highly resistive area from approximately 370
to 440 feet along the line. This resistive feature begins at approximately 75 feet bls, or
about the same depth as the resistive feature observed along Survey Line 1. The
conductive areas are located from 20 to >75 feet bls. All five conductive features are
consistent with the response of material with higher water saturation than the
surrounding material, similar to the features identified within Survey Line 1. The
groundwater surface in this area of the Site is typically located at approximately 18 feet
bls. Therefore, the depths of these conductive features are consistent with the depth of
the saturated zone in this area of the Site.
Several existing Site monitoring wells and recovery wells are roughly intersected by
Survey Line 2 as shown on Figure 1. The wells closest to Line 2 are indicated at the
top of the pseudosection on Figure 2 with the well name. The locations of a fiber optic
line and a gas line are also shown. The existing Recovery Well PP-8 is located near
the center of the conductive feature L2-A. This recovery well has historically produced

water at a significant flow rate typically ranging from 20 to 25 gallons per minute (gpm)
(Solutions EIS 2007). In contrast, adjacent Recovery Well PP-9, which is
approximately 110 feet east of PP-8, has historically recovered only 1 to 1.3 gpm.
Likewise, Recovery Well PP-16 located 55 feet east of PP-8 has historically recovered
only 1 to 1.2 gpm (Solutions EIS 2007). Note that PP-9 appears to be just on the edge
of the feature labeled as L2-B, and PP16 is not within any highly conductive feature.
Therefore, the differences in well yields suggest that these conductive anomalies are
areas with higher water saturation and higher permeability.
5.2.2 Magnetic Gradiometer Survey Results
A magnetic gradiometer survey was also run roughly parallel to Line 2, but on the
south side of the property line to avoid the metal fence. The line ran approximately
parallel to Durant Road. The gradiometer measures fluctuations in the earth's
magnetic field using two sensors at a fixed distance from each other. By subtracting
the readings of the two sensors, a magnetic susceptibility gradient is calculated. The
gradient is considered a more accurate way to measure magnetic susceptibility in the
shallow subsurface and has reduced interference from regional magnetic fields. The
results of the gradiometer survey are presented in the bottom panel of Figure 3. The
x-axis is distance and the y-axis is the change in magnetic field in the units of nT.
Mafic minerals in igneous and metamorphic rocks such as those underlying the Site
are relatively high in iron and therefore are easily magnetized. A weathered zone,
fault, or fracture in this material would have a lower magnetic susceptibility due to the
lack of these minerals and if the fault or fracture is large enough, could be detectible as
a drop (or change in the case of the gradient) in magnetic susceptibility response.
The gradiometer survey started at the same point as the resistivity line. At
approximately 125 feet along the survey line, a storm water drain was encountered.
The drain had a metal protective covering and produced a response in the gradiometer
as shown approximately 125 feet along the graph. Just after the storm drain was the
corner of the property at which two metal fences met to form a corner. The
gradiometer response from 150 to 200 feet along the graph is likely due to that feature.
The three responses of interest in the gradiometer graph are the ones at 325 feet,
400 feet, and approximately 475 feet. The gradiometer responses at 325 feet and at
475 feet correspond to the conductive anomalies in the top resistivity panel labeled as
L2-A and L2-C, respectively. These two features have the highest conductivity and
size on the section. The gradiometer response at 400 feet corresponds to the highly
resistive feature in the top panel, which likely is a large intrusive feature of differing
mineralogy from the surrounding rock(e.g., Roseville Batholith).

5.3 Survey Line 3-Electrical Resistivity Results
The inverted resistivity model for data collected along Survey Line 3 is presented on
Figure 4. A quality assurance check of the dataset indicated high quality data for the
majority of the line. The data removal was uniform throughout the dataset except for
the area approximately 650 feet down the line, which corresponds with the crossing of
an underground utility conduit (water/steam). The primary geologic features apparent
in the pseudosection are three highly conductive areas (labeled L3-A through L3-C)
and a large tabular highly resistive zone spanning from approximately 500 to 650 feet
along the line. The conductive areas are located from 30 to 50 feet bls. All three
conductive features are consistent with the response of material with higher water
saturation than the surrounding material. These areas are likely more porous and
therefore more saturated. Based on experience, these features are suggestive of
preferential flow paths. The large feature labeled as L3-B may appear larger than it
actually is due to interference from the underground steam/water utility line that
crosses the line at that point. The groundwater surface in this area of the Site is
typically located at approximately 25 feet bis. Therefore, the depths of these
conductive features are consistent with the depth to groundwater in adjacent
monitoring wells.
6. Conclusions and Recommendations
The resistivity results of all three lines are consistent with the current conceptual site
model that a fault, fracture, or other linear weathered zone is trending north-south
through the Site. The large conductive feature present in all three pseudosections is
approximately the same size and depth on each line. The conductive features are
presented in plan view on Figure 5 and labeled. The large conductive feature of
interest is designated as L1-B on Survey Line 1, as L2-A on Survey Line 2, and L3-B
on Survey Line 3. An alignment of these features can be inferred.
As presented in email correspondence to Mallinckrodt on June 4, 2010, ARCADIS
conducted a visual survey of a stream cut bank to the south of the Site which indicated
a zone of heavily weathered bedrock that generally aligns with the large conductive
feature observed in the resistivity pseudosections. The contact between the Rolesville
Batholith and the Raleigh Gneiss was examined in the stream channel. The older
Raleigh Gneiss has been injected with granitic dikes of the younger Rolesville
Batholith. Zones of the Raleigh Gneiss that appeared to contain extensive numbers of
granitic dikes are more resistant to weathering, whereas areas lacking extensive dikes
appear to weather more rapidly. Based upon this evidence, including the magnetic

gradiometer response, there is a strong suggestion that the conductive anomalies are
preferential flow paths and are acting as groundwater conduits across the Site.
However, all surface geophysical techniques provide a non-unique solution, meaning
that observed responses can be produced by numerous objects and should always be
confirmed using direct methods such as boring or cone penetrometry.
As presented in our proposal dated January 12, 2010, ARCADIS has developed a
detailed scope of work to evaluate the significance of the geologic features below the
Site and to transport chemical constituents present in groundwater below the Site
within apparent preferential pathways. ARCADIS is in the process of refining the
scope of work presented within that proposal based on the results of the surveys
conducted herein. Refinements to that scope of work will be presented to Mallinckrodt
in the near future. We plan to schedule a conference call during the week of July 26,
2010, to present the next phase of investigations, which likely will include:
1. Mobilization No. i - Installation of approximately seven MacroCoreTM soil
boring with a large truck-mounted Geoprobe'''to depths of approximately
70 feet bls to collect continuous soil samples along the depth of each boring.
Periodic soil samples will be collected for total organic carbon, as well as sieve
analysis and hydrometer testing (ASTM D422-63), characterization
(ASTM D2487), and moisture content(ASTM D2216-98)to help determine
potential variations in soil texture and particle sizes.
2. Mobilization No. 2 - Installation of approximately seven soil boring within
about 5 feet of each of the borings installed in Mobilization No. 1. These
borings would be installed with a large truck-mounted Geoprobe®to depths of
approximately 70 feet bls. ARCADIS would use the Waterloo Advanced
Profiling System (WaterlooAPs), which is a subsurface data acquisition system
that collects both groundwater samples and an integrated set data including:
a. Continuous Index of Hydraulic Conductivity;
b. Hydraulic head measurements; and
c. Physiochemical properties such as pH, specific conductance,
dissolved oxygen, and oxidation/reduction potential.
These data will be used in conjunction with the prior datasets to determine the
hydrogeological and physiochemical characteristics of the preferential flow pathways

below the Site. Successive phases of work will then be planned and designed to
determine the groundwater velocity and mass flux within the preferential flow pathways
in order to determine an overall remedial strategy for the Site.

Hi David, sorry for the slow response to your email from April 26, 2013,where you had indicated that"Very little
information is required" in the forms to request a permit extensions/renewal. Thus, I completed the 15t page only with a
note after Item 1 that refers to your April 26,2013 email. Is this sufficient? I am about to get client's signature, but
wanted to be sure this was adequate. Thanks for your input.
I hope you have a great weekend!

Hi Karen and Tim,
Do you agree with this email train,... extending both UIC permits for 5 years(or until June 30,
2018)? Otherwise, both permits will expire on June 30, 2014,and we might be doing this again
next year.
1 didn't want to speak for Mallinckrodt, but I think NCDENR is waiting on a response from us. •

Thanks David, We do not know with certainty when the injectant concentrations will be
reduced to background levels in either study area. Thus, I would like to minimize the effort
involved for everyone both now and in the future.
Question: Can you extend the time periods for both permits(W10500328 and W10500499)for 5
years (or until June 30,2018) based on Tim's or Karen's approval of this email train?
This would be the simplest and least costly solution for all parties. Tim's or Karen's approval
would be required though.

Thank you for your recent email. We are preparing to issue a short-term renewal ("extension of
the end date") for Injection Permit WI0500328 to conform to your request that the end date for
both this permit and Permit W10500499 end on June 30, 2014.
I would like to confirm that you would be content with the end date of June 30, 2014 and would
not consider a two-year or five-year extension on this permit(WI0500328).
Thank you.

Hi Dave,thanks for the response.
We are monitoring those same tracer wells within the UIC permit for the ERD system (WI0500499),which is set to expire
on June 30,2014. Perhaps you can set these both to expire on June 30,2014? That will make the paper work easy for
everyone.
Please let us know if we should discuss more,or if you need a formal letter request from Mallinckrodt.

Hi Donald,
Thank you for your recent email. I hope that you are well also.
It is our present policy to keep an injection permit active until such time as the concentration of the injectant in the
groundwater environment attains the 2L Groundwater Quality Standard concentration in all the sampled monitor wells
in those instances where a 2L Standard exists for the injectant.Since we have no Standard for fluorescein dye, quarterly
or semi-annual monitoring is required to continue until such time as the injectant dissipates, or the concentration
returns to the background level it was measured at prior to the injection activities. If the injectant does not dissipate or
begins to migrate, additional actions may be necessary.
The most recent monitoring data we have is the data associated and referenced in your email correspondence of July 5,
2012. If there is more recent monitoring data available,we would like to receive it. It is our understanding that there are
still detectable concentrations of the dye in some of the monitor wells, and this situation will require additional sampling
before the permit can be closed out.
Regards,
David Goodrich

Hi David,
Thanks for our discussion today! . It was nice talking to you.
This email is in response for your letter dated April 5,2011, requesting additional information for the UIC Permit Application for the
Mallinckrodt facility. Per our discussion and previous correspondence,we will'not be performing the"Phase II"injections at this time,
which were included within the original permit application.Therefore,the attached Figure 3 is a revised Site map of the facility that only
shows the"Phase I"locations. This figure uses a smaller scale so that it can be more easily read. It also details the locations of the
proposed tracer injection wells(in red font)and tracer monitoring wells(in green font). Per your request, I will also mail two copies of
this revised figure to you for your files. Also,this correspondence confirms that the six intended injection wells have been revised to
include wells BlaS, B3aD, PP-1S, PP-3S, FT-IS,and FT-2D.
Please let me know if you have any questions or comments.

Here is a revised figure for the UIC Permit. I spoke with David Goodrich, NCDENR this morning. He is pretty easy going, interested
in the project,and seems truly interesting in pushing this permit forward. He did say, however, it likely will be—3 weeks before they
will be able to finalize the Permit. He would like to get an email of the attached figure,and 2 color copies via mail.
I can handle both ASAP, but thought I would send this to you first. Per his April 5th letter, I will also confirm that the six intended

Any comments before I send to David. I will be happy to CC:you and Karen in the transmittal.

WI0500328 Permit Application
Mallinckrodt, Inc. Raleigh Pharmaceutical Plant
Groundwater Injection Tracer Well (5T), Wake County.
Dear Mr. Goodrich:
Mallinckrodt, Inc. Raleigh Pharmaceutical Plant is pleased to respond to your request for
additional information dated February 28, 2011 for the referenced permit application. The items
below are information requests followed by our response to comments:
1) The Unit understands that the Phase II Injection Area(Central Manufacturing Area) will not
be used for injection. Please submit a revised map the details injection well locations for the
Phase I Injection Area.
Figure 3 (attached) is a map showing the revised site layout for the UIC Permit
Application showing locations of monitoring wells proposed for the tracer testing.
2) The application requires construction diagrams/details for each of the wells that will be used
for injection. Please provide construction diagrams/details for each of these wells.
Based on the results offour soil borings installed at the site during February 2011, the
geologic feature might potentially be deeper and/or wider that originally anticipated
Therefore, ARCADIS respectfully requests the Aquifer Protection Section's approval to
adjust some of the tracer test locations to accommodate the potential width of the
geologic anomaly.

Response to Tracer Well Application Comments

The continuous recycle loop that ARCADIS proposes to use helps to ensure that tracer
solutions are applied evenly throughout the well volume while not creating artificial
mounding or depression of the water within the well. These procedures are discussed in
more detail within Remediation Hydraulics (Payne, Quinnan, &Potter, 2008). The
overall objectives of the test methodology are designed so that the resultant tracer wash-
out is due to natural groundwater flux, and not influenced artificially by recharge into or
discharge from the well. This system works by pumping groundwater from the bottom of
the well at a relatively low rate, the water is continuously added to an above-ground
continuous-flow mixing tank where the tracer concentrate is added, and then reapplied
back into the well without any net gain or loss of water from the well. The recycle loop
occurs for an approximate 2-hour period, or until stable tracer concentrations are
present within the recycle loop. A HachTMfeld spectrometer is used during the 2-hour
recycle period to check for stable tracer concentrations.
This continuous recycle loop replaces older tracer injection methods that would
otherwise utilize groundwater as a diluent within an aboveground batch-mix tank
Batch-mix methods initially cause a depressed groundwater table, as a large slug of
groundwater is quickly removed from the well. A subsequent groundwater mound also
occurs when the dilute tracer solution is re-injected back into the well. Therefore, the
continuous recycle loop is a better method of applying tracer compounds because it does
not affect the groundwater hydraulics surrounding the injection wells.
4) Wells must be monitored for any contaminant migration which is caused by the injection
process. Contaminant monitoring should take place in upgradient wells FT-2S and FT-2D, in
sidegradient wells FT-1 S and FT-1D; or at OS-12B and OS-12D; or at OS-13B and OS-13D,
and in downgradient wells OS-7B and OS-7D. PIease submit a plan for monitoring these
wells for contaminant migration during and after the injection process.
ARCADIS proposes to utilize a HachTMfield spectrometer to check for the potential
presence of fluorescein dye within the following monitor wells up-gradient, side gradient,
and down-gradient monitor wells.
a. Upgradient monitor wells: OS-3
b. Side-gradient monitor wells: OS-12B, OS 12D, and OS-ll
c. Down-gradient monitor wells: PP-18D and PP-20D
Grab samples will be collected from these wells during baseline sampling prior to the
injection activities, and then 6 weeks after the injection activities, and 6 months after the
injection activities. Groundwater samples for volatile organic chemicals are not
proposed herein because the injection hydraulics associated within the continuous
recycle loop do not cause adverse groundwater flow because there is no net gain or loss
of injection fluids during the injection portion of the tests.

IL EVALUATION AND RECOMMENDATIONS
1. Permit application is regarding the renewal without modification of permits WI0500328 and WI0500499.
WI0500328 was permitted for injection of tracer dye.WI0500499 was permitted for injection of molasses and
tracer dye.Perrnittee is requesting the permits are extended for five years or until June 30,2018. Submitted
reports(Injection Event Record 12-19-13) indicate that injection for WI0500499 was initiated in late October
2012 and completed by November 2012.Because the injection event was recently completed,permit renewal
will only cover groundwater monitoring until late 2013 per the original permit.Recommendations: 1. Extend
groundwater monitoring requirements in the permit renewal(beyond previous permit requirements in
WI0500499)to quarterly 2. Following one year of data demonstrating no issues with the injection event,
annual reporting of monitoring data would be sufficient to observe permit compliance.
Attach Well Construction Data Sheet- if needed information is available
2. Do you foresee any problems with issuance/renewal of this permit? Yes ®No. If yes,please explain
briefly.
3. List any items that you would like APS Central Office to obtain through an additional information request.

Dave,
In regards to the request to close out this permit(W10500328):fluorescein (the injectant) is currently present in several
monitoring wells at the facility at a concentrations as elevated as 266 part per billion in the injection area. It appears
that it is not present in significant concentrations outside and upgradient of the injection area.Also,there is no
established 2L groundwater standard for fluorescein. In light of this information it is recommended that this permit
remain active and groundwater monitoring continue in the appropriate wells until such time that the injectant dissipates
or the concentrations return to a measured background level prior to injection.Additional actions may be necessary if
the injectant does not dissipate or begins to migrate.

V. EVALUATION AND RECOMMENDATIONS
1. Provide any additional narrative regarding your review of the application.: Permit application is regarding the
injection of fluorescein as a tracer to define groundwater velocity in various site geologic settings. The intent is
to gain a better understanding of the hydrogeology and to use the trace data to develop a suitable corrective
action for the site. Injection areas listed in the application are designated as "Phase I" and"Phase II".Total
volume to be injected is given as 500 gallons per well in a continuous recycle loop at a concentration of
approximately 40 mg/L. At the time of the inspection it was indicated that two injection wells will be installed
for the event in the Phase I injection area and that this will be the total installed for the injection event.The
number of injection wells differs from the application because it was stated that it has been decided that the
Phase II injection area will not be used.The injection is to be conducted at atmospheric pressures or not to
exceed five pounds per square inch.Following injection samples will be collected and analyzed off site for the
fluorescein.There are several recovery wells that operate as a part of the active remediation system which will
be in operation downgradient of the injection area. Injection will begin in the first injection well and the second
injection well will be used for monitoring. Then, injection will take place in the second injection well and PP-8
(recovery well)will be utilized as an observation well.
Recommendations/request: 1.Request a revised map that details injection well locations for Phase I injection
area 2. Well diagram of injection wells 3. Explain what is meant by injection in a continous recycle loop [Part
2.4 B. 3.] 4.Monitoring of wells for any contaminant migration due to the injection. Upgradient: FT-2S and

SUBJECT: Lizzie Intensive Study Area •
Use of Fluorescein as a Fluorescent Groundwater Tracer in Lizzie,North Carolina
I am writing in response to a request from Duke University for a health risk evaluation ,
regarding the use of fluorescein as a fluorescent groundwater tracer in Lizzie,North Carolina.
Based upon my review.of the information submitted, I offer the following health risk evaluation:
WORKER PRECAUTIONS DURING APPLICATION -
1. Some effects reported to be associated with the product proposed to be used are as
follows: eye, skin, nose, throat, and lung irritation. If the product is released into the
environment in a way that could result in a suspension of fine solid or liquid particles
(e.g., grinding, blending,vigorous shaking or mixing),then proper personal protective
equipment should be used. The application process should be reviewed by an industrial, .
hygienist to ensure that the most appropriate personal protective equipment is used.
2. Persons working with this product should wear goggles or a face shield, gloves, and
protective clothing. Face and body protection should be used for anticipated splashes or
sprays.
3. Eating, drinking, smoking,handling contact lenses, and applying cosmetics should not be
permitted in the application area during or immediately following application. :.;
4. Safety controls should be in place to ensure that the check valve and the pressure delivery
systems are working properly.
5. The Material Safety Data Sheets be followed to prevent adverse reactions and injuries.

Memo: Lizzie Intensive Study
July 31, 2000
Page Two
OTHER PRECAUTIONS
1. Access to the area of application should be limited to the workers applying the product.
In order to minimize exposure to unprotected individuals, measures should be taken to
prevent access to the area of application.
•
2. According to the July 7, 2000 memorandum prepared by Mr. David May with the
Groundwater Section of the Washington Regional Office, the closest residences to the
• proposed injection area are served by public water supplies that are distantly located from •
the injection area, and there are no occupied houses in the vicinity of the injection wells.
According to Mr. May, the area surrounding the injection site is predominantly wooded
or agricultural fields and installation of new wells is not anticipated. Based on this
information, it is unlikely that this tracer would contaminate an existing water supply,
however, measures should be taken to prevent contamination of-existing or future wells
that may be located near the application area.
3. According to the July 6, 2000 letter prepared by Duke University, many of the injection
wells are in proximity and upgradient to Ted's Creek, Sandy Run Creek,and Middle
• Swamp, and fluorescein could discharge into these waters. However, according to Duke
University, impact to surface waters would be minimal because most, if not all of the
tracer, travels less than a foot from the wells and approximately 50% of the tracer will be
removed by filtration. According to Duke University, the concentration of fluorescein
near these waters is expected to be far below the detectable limit of approximately 1 ug/L.
Because of the proximity of the injection wells to these waters, it is recommended to
consult with Ms. Dianne Reid with the Water Quality Section at(919) 733-5083
extension 568 to determine if this product could impact these waters.
Please do not hesitate to call me if you have any questions at [phone].

Dear Katherine:
Mallinckrodt LLC is pleased to submit one original copy and one electronic copy (CD) of the
Performance Monitoring Report that summarizes the construction, injection, and follow-on monitoring
activities for the Enhanced Reductive De-chlorination (ERD) Pilot Test at our Pharmaceutical Plant in
Raleigh,North Carolina. The overall purpose of the pilot test was to evaluate the capability of ERD to
control the horizontal and vertical migration of various site constituents in groundwater. The
construction, injection, and monitoring activities were executed in accordance with the combined
Underground Injection Control (UIC)permit application and work plan submitted to the North Carolina
Department of Environment of Natural Resources (NCDENR) Division of Water Quality, Aquifer
Protection Section (APS) on March 27, 2012. On July 6, 2012, the NCDENR-APS issued Injection
Permit No: WI10500499 and granted approval to proceed with the specified injection program. The UIC
Permit currently expires on June 30,2018.
You may have recently received a letter from us dated August 2,2013,which contained our responses to
NCDENR's comments to the Corrective Action Cost Estimate. Figure 1 of that letter presented various
activities currently planned during 2013 to support the future development of a Corrective Measure
Study for the site. As presented in Figure 1,the activities to be completed during 2013 include:
• Continued monitoring of the ERD Pilot Test,
• Assess the status of Solid Waste Management Units (SWMUs), Areas of Concern (ADCs), and
No Further Action Requests, where appropriate,
• Meeting with NCDENR to discuss SWMU/AOC Status,
• Re-assess potential remedial strategies for active SWMUs(i.e.,Tannin Pits, S. MASL Ponds),
• Develop a Site Conceptual Model,
• Develop a groundwater fate and transport model,and
• Evaluate Vapor Intrusion for industrial buildings within 100-feet of impacts.

The Aquifer Protection Section is in receipt of the Final Project Evaluation Report for UIC Permit W10500328 for injection
events which took place at the Mallinckrodt LLC Raleigh Pharmaceutical Plant.The sampling plan called for the sampling
of each of the six injection wells immediately after injection and subsequently at 1, 2, 3, 7, 14, 28, and 42 days after
injection. Six permanent monitor wells that are situated beyond the injection area were to be sampled before the
injections, and then, six weeks after and six months after the injections take place. The sampling results for these
sampling events have not been reported to our Section, and appear to be missing from the Final Project Evaluation

Hi Dave,
Please take a look at the information below, and let me know if you would like a formal letter of this response. The sampling of six
injection wells was performed as noted in the permit,...the results of which were included in the charts in Attachment 3 of the report. It
appears, however, that we did not include the laboratory reports(attached)within the report. We did make a few minor changes to the
monitoring program because it made sense at the time, and possibly did not inform the NCDENR-APS of this modification. I hope the
information contained herein is adequate justification for the changes that were made.
• Day 14 samples for the injections wells were collected on Day 15 (May 31st, 2011)
• Day 28 samples for the injections wells were collected on Day 29(June 14th, 2011)
• Day 42 samples for the injections wells were not collected because we had adequate information for determining tracer
washout rates. Instead, additional samples were collected for the injection wells later in the monitoring program (see last
bullet item below).
• Week 6 samples for the monitor wells were on about Week 9 (July 18'h, 2011)due to scheduling conflicts. No tracer was
present in any of the monitor wells (except in OS-12B at a very low estimated concentration [0.020 parts per billion{Deb)).
This likely a laboratory analytical artifact.
• Month 6 samples for the monitor were not performed until Month 9 (February 23, 2012) due to funding constraints. This
duration made sense anyway because a little tracer remain in a few samples during the earlier periods.
• Month 9 samples for the injection wells were not specified within our earlier correspondence, but were collected anyway.
ARCADIS substituted these samples for the samples originally specified on Day 42. No tracer was present in any of the
monitor wells(except in OS-3 at a very low estimated concentration of 0.094 opt. Again, this likely a laboratory analytical
artifact.
Note: The Month 9 samples for the tracer and monitor wells were included in Table 5 of the Final Project Evaluation Report.

H:,
I was cnecking in the samples you sent to us on 5/23/2011 for the Mallinckrodt project and noticed that
the samples collected on 5/23/11 were labled differently on the COC,then on the sample vials. The COC
ends all the samples collected on the 23rd with 0518 instead of 0523 as on the vials. Do you want us to
,ise the name as noted on the COC or as on the vial? If the COC is incorrect do you want to send us a
new COO or have us correct the one sent to us?
Thank you.
