EXECUTIVE SUMMARY
In 2005, full-scale subsurface injection of Zero Valent Iron (ZVI) and molasses slurry was
conducted at the former Hamilton Beach Brands, Inc. manufacturing facility in Washington,
North Carolina. The slurry injection was the second phase of corrective action measures
implemented at the site to mitigate a plume of chlorinated organic compounds dissolved in
groundwater through a process of in-situ degradation.
In accordance with the state-approved Corrective Action Plan, initial performance monitoring
spanned a period from August 2005 to August 2006, concluding one year after ZVI injection was
completed at the site. The analytical results from eight sampling events were documented in a
One Year Post-Injection Monitoring Report. The report also discussed a kinetic model that
described the degradation process and estimated the time until cleanup goals would be
approached. As recommended in the One Year Post-Injection Performance Monitoring Report,
an additional round of performance monitoring was conducted in April 2007. Monitoring results
from the Twenty Month Post-Injection Performance Monitoring Report indicated that remedial
progress continued at the site in both Unit A and Unit B, but suggested that more time than
initially predicted may be needed to approach cleanup goals throughout the plume.
Following the recommendations in the Twenty Month Post-Injection Performance Monitoring
Report, URS initiated a semi-annual long-term monitoring program in April 2008. This program
also serves to continue monitoring the performance of the installed ZVI remedial system. During
the latest long-term monitoring event, conducted on October 29 and 30, 2008, groundwater
samples were collected from 16 monitoring wells and one sampling implant.
Groundwater analytical results indicate that generally good progress in reducing chemical
concentrations is occurring in both Unit A and Unit B, despite persistent high concentrations of
chemicals of concern within Unit A near the source area. Overall, however, the total
concentration of chlorinated organic compounds has decreased from maximum recorded levels at
16 of the 17 groundwater sampling points. The percentage decrease in concentration ranges from
15 percent to essentially 100 percent, depending on location. Analytical results also suggest that
complete reductive dechlorination is occurring, which will ultimately reduce the concentrations
of intermediate degradation compounds that have accumulated in several parts of the plume.
This report presents the results of the long term monitoring, discusses the continued performance
of the in-place remedial system since ZVI injection was completed, and identifies any trends and
changes in subsurface conditions since the previous monitoring event in April 2008.

1.0 INTRODUCTION
This document is the second post-injection long term monitoring (LTM) report for the former
Hamilton Beach Brands, Inc. (HBB) manufacturing facility located at 234 Springs Road in
Washington, North Carolina. This report was preceded by the One-Year Post Injection
Performance Monitoring Report (URS Corporation-NC et al., 2007a), the Twenty-Month Post
Injection Performance Monitoring Report (URS Corporation-NC et al., 2007b), and the first
Long Term Monitoring Report (URS Corporation-NC, 2008). Historical performance monitoring
data are tabulated in Appendices A-1 through A-3.
This report addresses long-term monitoring conducted on October 29 and 30, 2008,
approximately 38 months after the injection of Zero Valent Iron (ZVI) and molasses slurry was
completed at the site. The purpose of the report is to present the results of monitoring, evaluate
remedial trends, and assess the performance of the injected ZVI in promoting the degradation of
dissolved chlorinated organic compounds underlying the site.
1.1 Site Description and Background
The site is an irregularly-shaped parcel over 39 acres in size, of which 30 acres are occupied by a
plant building, several storage buildings, parking areas, and landscaped grounds. Until HBB
discontinued manufacturing operations in December 1998, the facility was used to assemble,
package, and warehouse small, electric, household appliances. Chemicals were initially detected
in groundwater at the site in 1992. Several phases of investigation culminated in a
Comprehensive Site Assessment Report (Radian International LLC, 1999) that characterized site
conditions and identified various organic chemicals in soil and groundwater. The chemicals of
concern (COCs), primarily chlorinated solvents and their degradation compounds, occur as a
dissolved plume within two hydrostratigraphic units. These include a shallow, unconfined unit
comprised of low permeability materials (Unit A) and an underlying semi-confined unit
comprised of more permeable silty-sand (Unit B).
A state-approved Corrective Action Plan (URS Corporation-NC, 2002) recommended a two-
phased remediation approach. Phase 1 involved applying Electrical Resistance Heating (ERH)
between December 2003 and July 2004 to address impacted soil and groundwater in the source
area. Implementation of ERH at the site is documented in a source removal report (URS
Corporation-NC et al., 2005). Phase 2 of the remediation approach involved injecting ZVI and
molasses slurry into affected portions of Units A and B to address the remaining areas of the
dissolved groundwater plume. The injection process, which was authorized by an Underground
1-1 February 2009
Long Term Monitoring Report HBB Washington, NC

Injection Control Permit (W10700041) issued in April 2003, is described in the Injection
Summary Report (URS Corporation-NC et al., 2006).
1.2 Overview of ZVI and Molasses Slurry Injection
The full-scale subsurface injection of ZVI and molasses slurry was conducted from February 10,
2005 to August 12, 2005. This remedial approach was selected after the results of a 2001 pilot
test (URS Corporation-NC et al., 2002) indicated that iron powder and molasses could
effectively remediate the plume of dissolved chlorinated organic compounds underlying the site.
The first phase of the injection project involved supplemental sampling to refine the horizontal
and vertical delineation of chlorinated organic compounds in groundwater and soil at the site.
The results from supplemental sampling were used to improve estimates regarding the
distribution of the chlorinated COCs. These data were then used to update the subsurface
injection plan.
During the project, 103 tons of ZVI and approximately 36,000 gallons of feed grade molasses
were injected into 1,407 direct push bore holes. A total of 4,645 injections were completed at
varying depths throughout the plume.
1.3 Report Organization
Section 1 of this report provides a brief description of the site and the COCs along with an
overview of corrective action measures implemented at the site. Section 2 briefly discusses the
sampling and analysis methods. Section 3 presents and discusses the results obtained for the
sampling points monitored through October 2008. Conclusions are provided in Section 4 and
recommendations are contained in Section 5. A list of references is found in Section 6.
Supporting data are included in the appendices.

2.0 SAMPLING PROCEDURES
Sixteen monitoring wells and one sampling implant (M-2) were sampled on October 29 and 30,
2008. The sampling points included the 13 wells in the LTM network plus four supplemental
sampling points (NW-F-2, NW-G-12, NW-K-6, and M-2). The LTM wells, the supplemental
wells, and the sampling implant are listed on Table 2-1 together with their construction details.
As shown in Figure 2-1, eleven monitoring wells are located in Unit A and five wells and the
sampling implant are located in Unit B.
Prior to sampling, the monitoring wells were purged of three well volumes of water or, at wells
MW-211, MW-219, and NW-P-0, until dry. Two-inch diameter wells were purged with new,
disposable bailers, whereas half-inch and one-inch diameter wells were purged with a peristaltic
pump equipped with new sample tubing. Field parameters (temperature, pH, specific
conductance, dissolved oxygen, and oxidation-reduction potential) were measured after purging
with a calibrated YSI 556 MPS meter. Approximately 15 gallons of purge water was collected in
a 55-gallon drum and staged on the north side of the hazardous materials building for subsequent
disposal.
After purging was completed, groundwater samples were collected in appropriate laboratory-
supplied sample containers. The filled containers were immediately stored in a cooler filled with
wet ice. Following the completion of sampling, the groundwater samples and a trip blank were
shipped under chain-of-custody protocols for next-day delivery to Accutest Laboratories
Southeast (Accutest).
All of the groundwater samples were analyzed for volatile organic compounds (VOCs) by
Method SW 846 8260B. Samples from wells MW-ERH2 and MW-GAW2 were also analyzed
for semivolatile organic compounds (SVOCs) by Method SW846 8270C. The target analyte lists
for VOCs and SVOCs were developed in the state-approved corrective action plan. Chloroethane
was added to the VOC list as an additional indicator of dechlorination. Samples from wells MW-
ERH2, MW-229, NW-D-9, MW-227, NW-AB-19, and NW-E-9 were also analyzed for
dissolved gases (methane, ethane, and ethene) by Method RSKSOP-147/175 to evaluate whether
complete degradation is occurring.

Long Term Monitoring Report HBB Washington, NC

3.0 MONITORING RESULTS
October 2008 represents a period of 38 months since iron injection at the site was completed.
The COC degradation patterns should now be established and the overall concentration of
chlorinated organic compounds should be following a relatively well-behaved declining trend.
This section presents the latest analytical results and interprets the results over the period of
record to assess the performance of the injected iron in promoting the degradation of the
chlorinated organic compounds in groundwater underlying the site.
URS Corporation – North Carolina (URS) reviewed the analytical results from each sampling
point. The evaluation of the data was modeled after the Contract Laboratory National
Functional Guidelines for Organic Data Review (US EPA, 1999). Sample results were qualified
according to the data review process and data qualifiers were added to the analytical results, as
needed. The analytical results tabulated in this section reflect the results of the data qualification.
Laboratory reports are included in Appendix B.
3.1 Unit A
Table 3-1 summarizes the analytical results for the groundwater samples collected from 11
monitoring wells completed in Unit A. The table also lists the groundwater quality standards (2L
Standards) for Class GA groundwater. The well locations are shown on Figure 2-1.
Nineteen VOCs were detected during this sampling event, 10 at concentrations that exceeded the
2L Standards in one or more wells. No VOCs exceeded the 2L Standards in well MW-219 and
only 1,1-dichloroethene exceeded the 2L Standard by less than 1 microgram/Liter (µg/L) at well
NW-F-2. Well MW-211, which exceeded the standard for only cis-1,2-dichloroethene during the
previous sampling event exceeded the standards for cis-1,2-dichloroethene, 1,1-dichloroethene,
and vinyl chloride during this event. In contrast, the highest concentrations of analytes reported
were associated with wells NW-D-9, MW-ERH2, and NW-K-6.
Consistent with previous sampling results, the VOCs that were detected were primarily
chlorinated solvents and their degradation compounds. However, benzene and naphthalene were
also detected above the 2L Standards at several monitoring wells located in an area where
petroleum constituents have historically been reported. Also detected in this area were other
petroleum-related VOCs that were below the 2L Standards and two petroleum-related SVOCs, 2-
methylnaphthalene and 3&4-methylnaphthalene.

Long Term Monitoring Report HBB Washington, NC

3-6 February 2009
The total concentration of chlorinated organic compounds (TCOC) at a monitoring well was
calculated by summing the concentrations of the following eight COCs: 1,1,1-trichloroethane
(111TCA), 1,1-dichloroethane (11DCA), 1,1-dichloroethene (11DCE), chloroethane (CA), cis-
1,2-dichloroethene (cDCE), tetrachloroethene (PCE), trichloroethene (TCE), and vinyl chloride
(VC). The TCOC at each of the 11 Unit A wells sampled in October 2008 is shown in Table 3-2
along with the TCOC measured during the previous sampling event in April 2008. The table also
shows the percent differences between the TCOC on these dates and between the maximum
TCOC measured during the period of record. Of these 11 wells, TCOC has decreased from the
maximum recorded value at 10 wells. The decrease from the maximum TCOC ranges from 15
percent at well NW-K-6 to 98 percent at well MW-229. However, the TCOC measured at well
MW-ERH2 again represents a new maximum value at that location. A possible explanation for
this phenomenon is that COCs remain sorbed to the soil where they react with the injected iron
and cause an increase in the concentrations of degradation compounds, such as cDCE and VC.
This appears to be a localized effect limited to the area near well MW-ERH2 because the TCOC
at well MW-GAW2, which is located less than 50 feet away, exhibits an 88 percent decrease
from its maximum recorded value.
In the six-month period between April 2008 and October 2008, the TCOC decreased in seven
wells and increased in four wells. Nevertheless, the TCOC remained below the maximum level
recorded at those locations where an increase in concentration was measured. In general, the
greatest reduction of TCOC in Unit A, on a percentage basis, appears to be occurring in the distal
portions of the northeastern and southeastern plume lobes.
Graphs included in Appendix C-1 complement the evaluation of trends in TCOC. The graphs
plot the concentrations of the eight COCs that comprise TCOC and include data from LTM
sampling, performance monitoring, and pre-injection plume delineation. Generally decreasing
trends in the concentrations of COCs are shown in a majority of the graphs. For example, graphs
for wells NW-P-0, MW-229, and NW-F-2 illustrate the decreasing COC concentrations in the
northeastern and southeastern lobes of the plume mentioned earlier. Graphs for most other wells
also depict generally declining trends, although not as pronounced. Only for wells MW-ERH2
and NW-K-6 do the graphs indicate stable or, possibly, rising concentrations. The graphs are also
useful in explaining the increases in TCOC identified at several wells. In most cases, the
increases can be attributed to increasing concentrations in one or more degradation compounds,
such as cDCE at well MW-211.
Despite the apparent accumulation of degradation products at some wells, the presence of ethene
and ethane in groundwater (see Table 3-1) at greater than background concentrations (typically

less than 0.0005 mg/L) suggests that complete reductive dechlorination is occurring and
ultimately the degradation products will be eliminated. Also, elevated levels of methane (see
Table 3-1) indicate that biodegradation processes may also be occurring in addition to the abiotic
reductive dechlorination attributed to ZVI injection. The presence of methane, which is produced
and persists only in the absence of oxygen, suggests that dissolved oxygen (DO) concentrations
measured in some wells may be uncharacteristically high, possibly due to the entrainment of air
in the samples during measurement.
The concentrations of individual COCs detected historically in Unit A wells during long term
monitoring are tabulated in Appendix D-1.
3.2 Unit B
Table 3-3 summarizes the analytical results for the groundwater samples collected from five
monitoring wells and one sampling implant (hereafter referred to as a well) completed in Unit B.
The table also lists the groundwater quality standards (2L Standards) for Class GA groundwater.
The well locations are shown on Figure 2-1.
Fifteen VOCs were detected, seven at concentrations that exceeded the 2L Standards in one or
more wells. At least two VOCs exceeded the 2L Standards in each of the six wells sampled.
Consistent with previous sampling results, the VOCs were primarily the degradation compounds
of chlorinated solvents. Isolated detections of benzene, ethylbenzene, toluene, and xylenes were
also reported; however, other than benzene in well MW-227, concentrations of these petroleum-
related compounds were well below the 2L Standards. No other VOC, except 1,2-dichloroethane,
exceeded the 2L Standards in well MW-227. As noted in the previous monitoring report, the
level of improvement in water quality at MW-227 was not anticipated at this time. Although
apparently confirmed by the latest analysis, the results are considered anomalous and warrant
continued monitoring. In contrast, the highest concentrations of analytes in Unit B were reported
in the southern lobe of the plume at well NW-E-9 and in the northern lobe of the plume at wells
NW-R-14 and NW-AB-19.
The TCOC at each of the Unit B wells sampled in October 2008 is shown in Table 3-4 along
with the TCOC measured during the previous sampling event in April 2008. The table also
shows the percent differences between the TCOC on these dates and between the maximum
TCOC measured during the period of record. The table indicates that the TCOC has decreased
from the maximum value recorded for the period of record at all six wells. The decrease from the
maximum recorded TCOC ranges from 51 percent at well M-2 to essentially 100 percent at well

Long Term Monitoring Report HBB Washington, NC

MW-227. In the six-month period between April 2008 and October 2008, the TCOC increased in
three wells and decreased in three wells. The six-month increase in TCOC ranged from 26
percent at well NW-E-9 to 121 percent at well MW-227. However, the change measured at MW-
227 is not considered significant as it represents an increase in concentration of only 16 µg/L to
30 µg/L. Conversely, the decrease in TCOC over six months ranged from 27 percent at well
MW-209 to 78 percent at well NW-R-14. The TCOC at well NW-R-14 and also at NW-AB-19
exhibit a continued decreasing trend in the northern lobe of the plume following a prolonged
rebound in concentration that began in the second half of 2006 and continued into 2007.
However, unlike in Unit A where the greatest TCOC reduction is occurring in the lobes of the
plume, the greatest percent reduction in TCOC in Unit B appears to be taking place near the
source area.
Graphs for the six wells sampled in Unit B, which plot the concentrations of the COCs that
comprise TCOC, are included in Appendix C-2. The majority of the graphs show a declining
trend in COC concentrations suggesting that degradation compounds are themselves being
degraded at a rate that is greater than that at which they are being formed. Only at wells NW-E-9
and M-2 do concentrations appear to be stable or rising.
As in Unit A, the presence of ethene and ethane (see Table 3-3) at greater than background
concentrations suggests that complete reductive dechlorination is occurring. Also, elevated levels
of methane (see Table 3-3) indicate that biodegradation processes may also be occurring in
addition to the abiotic reductive dechlorination due to ZVI injection.
The concentrations of individual COCs reported historically in Unit B during long term
monitoring are tabulated in Appendix D-2.

Long Term Monitoring Report HBB Washington, NC

4.0 CONCLUSIONS
Good progress is occurring throughout most of the plume in Unit A as evidenced by a decrease
in TCOC from the maximum levels measured in 10 of the 11 wells sampled. However, TCOC at
source area well MW-ERH2 again represents a new maximum value at that location. This
localized phenomenon is likely due to COCs that remain sorbed to the soil where they react with
the injected iron and cause an increase in the concentrations of degradation compounds, such as
cDCE and VC. On a positive note, the rebound in TCOC noted at source area well MW-GAW2
and at well MW-213 during the previous sampling event has reversed. Elsewhere within the
plume in Unit A, COC concentrations continue to decline as anticipated with the greatest
reduction in TCOC taking place at the plume’s northeastern and southeastern lobes.
Generally, good progress continues to be measured in Unit B, also, as TCOC in all wells have
decreased from maximum levels for the period of record. At the majority of the wells, COC
concentrations continue to exhibit a decreasing trend, including wells located along the northern
lobe of the plume where TCOC had rebounded in 2006 and 2007. However, concentrations in
the eastern and southern lobes of the plume currently are stable or rising slightly as degradation
compounds are, temporarily, being formed more rapidly than they can be degraded.
Despite the accumulation of degradation compounds such as cDCE and VC in some wells, the
formation of ethene and ethane indicates that complete reductive dechlorination is occurring in
Unit A and Unit B. Consequently, the accumulation of degradation compounds is expected to
slow and their concentrations decrease as the rate of degradation surpasses the rate of formation.
Furthermore, elevated levels of methane detected in groundwater indicate that biodegradation
processes may be occurring in addition to the abiotic dechlorination attributed to ZVI injection.

Long Term Monitoring Report HBB Washington, NC

5.0 RECOMMENDATIONS
Long-term groundwater monitoring should be continued to evaluate the degradation of COCs at
the site. As recommended in the most recent groundwater monitoring report (URS Corporation-
NC, 2008), eight wells in Unit A (MW-ERH2, MW-GAW2, MW-211, MW-213, MW-219,
MW-229, NW-D-9, and NW-P-0) and five wells in Unit B (MW-209, MW-227, NW-AB-19,
NW-E-9, and NW-R-14) that comprise the LTM well network should be sampled semiannually
in April and October of each year. Samples from all LTM wells should be analyzed for VOCs.
Samples collected from wells MW-ERH2 and MW-GAW2 should also be analyzed for SVOCs.
To confirm that complete degradation is occurring, dissolved gas (ethane, ethene, and methane)
samples should continue to be collected from wells MW-ERH2, MW-229, and NW-D-9 in
Unit A and wells MW-227, NW-AB-19, and NW-E-9 in Unit B.
In conjunction with the LTM wells, samples should also be collected from wells NW-F-2,
NW-G-12, and NW-K-6 in Unit A and sampling point M-2 in Unit B. Samples from these
points, which should be analyzed for VOCs only, will provide supplemental data for assessing
the progress of remediation. Monitoring of these sampling points will be terminated when data at
these locations are no longer warranted.
Surface water should be re-sampled during the April 2009 LTM event, provided that flow in the
ditch is low and originates primarily as groundwater discharge. Otherwise, surface water
sampling should be delayed until October 2009 when baseflow conditions are more likely to
predominate. Surface water samples should be collected from sampling points W81 and W82
(see Figure 2-1) and analyzed for VOCs.
Lastly, the protective casing installed over well MW-229 has been damaged by rust and should
be repaired or replaced.
