1.0 Onsite Activities
The following activities were conducted during the Second Quarter 2015.
■
On May 13, 2015, an updated Site-Specific Risk Assessment (SSRA) for the former Kop-Flex facility
was submitted to the Maryland Department of the Environment (MDE). Pursuant to MDE’s request,
the previous (2009) SSRA was updated to incorporate (1) the results of investigation and
remediation activities conducted after 2009, (2) the change in future property use from industrial to
commercial, and (3) the current toxicity information and risk characterization methods.
MDE provided technical comments on the updated SSRA via electronic mail on June 12, 2015.
WSP and Emerson reviewed the comments and revised the risk assessment accordingly. The
revised SSRA document, which included responses to the comments, was submitted to MDE in early
July 2015.
■
A Response Action Plan (RAP) for the onsite area was prepared and submitted to MDE and U.S.
Environmental Protection Agency (EPA), Region III on June 2, 2015. The RAP describes the
proposed remedial actions for addressing volatile organic compounds (VOCs) present in the soil and
groundwater on the Kop-Flex property. The plan also includes supporting plans (e.g., Soil
Management Plan and Groundwater Monitoring Plan) to be followed during the implementation of the
proposed remedial activities.
■
All onsite monitoring wells and offsite well MW-24D on the adjoining Williams-Scotsman property, were
sampled the week of June 15, 2015. This sampling event was a continuation of the semi-annual
groundwater monitoring activities at the Kop-Flex VCP site.
A synoptic round of water level measurements was obtained at the beginning of the sampling activities.
A contour map of the groundwater surface, or water table, for the surficial (unconfined) zone at the
former Kop-Flex facility is shown in Figure 1. The hydraulic head contours indicate a generally
westward flow direction toward Stony Run, which is consistent with the evaluation of previous
hydrologic data from this portion of the aquifer system. Figure 2 depicts the potentiometric surface
contours for the deeper (semi-confined) portion of the Lower Patapsco aquifer based on the contouring
1
of water level data from both on and offsite wells. The hydraulic head data indicates a generally southsoutheast flow path for groundwater in the deeper semi-confined zone.
The analytical results for the June 2015 groundwater monitoring event are summarized in Table 1.
Historical data (2009 to June 2015) for the onsite monitoring wells are summarized in Table 2. (Copies
of the laboratory reports for these samples are provided in Enclosure A.) For wells completed in the
surficial (unconfined) zone north and west of the former manufacturing building, the VOC distribution
indicated by the June 2015 analytical results is similar to data from previous sampling events (Figure
3). The shallow (MW-07) and intermediate-depth (MW-18 and MW-39) perimeter wells continue to
show no VOCs at levels of concern. Even though the 1,4-dioxane concentration in the MW-03 sample
(7.5 micrograms per liter [µg/l]) is slightly above the MDE risk-based level, evaluation of the sampling
results indicate site-related COCs are not migrating offsite in the surficial portion of the aquifer. The
VOC distribution in the surficial zone east of the building is also generally consistent with previous
monitoring results (Figure 3). Total VOC concentrations in samples from shallow and intermediatedepth wells immediately east of the former manufacturing building are similar to historical levels, and
reflect the temporal fluctuation in constituent concentrations in the aquifer. The continued decrease in
VOC concentrations at the MW-15 location may reflect biotic and abiotic degradation activity
associated with the emulsified zero-valent iron injection in 2013 (Table 2). Samples from wells south of
the building (MW-01, MW-06, MW-14 and MW-17) showed non-detect levels for 1,4-dioxane and siterelated chlorinated VOCs. For deeper wells screened in the semi-confined portion of the Lower
Patapsco aquifer, the VOC concentrations for the June 2015 samples are similar to historical levels
(Figure 4). The only notable exception is the sample collected from well MW-17D near the southeast
corner of the building, where the concentrations of chlorinated VOCs and 1,4-dioxane continue to show
a noticeable reduction compared to historical data (Table 2). The decrease in VOC concentrations at
this well location could be linked to mass removal during the pumping test activities conducted in the
spring of 2014.
■
As part of the June 2015 semi-annual monitoring event, field data were collected from Stony Run to
determine the discharge for the reach of this stream on the Kop-Flex property. The hydrologic data
were obtained at three times during the field activities and included measurements of stream stage
using a staff gage and flow velocity. Evaluation of the hydrologic measurements indicates discharge
values for Stony Run ranging between 3.7 cubic feet per second (cfs), which equates to 1,650
gallons per minute (gpm), to 5.7 cfs, or 2,560 gpm.
■
A public informational meeting involving representatives of Emerson, WSP, MDE, and the property
developer (Trammell Crow) was convened on June 24, 2015, at the Anne Arundel Community
College at Arundel Mills campus in Hanover, Maryland to (1) obtain public input concerning the RAP
submitted to MDE in early June, and (2) provide an overview of the offsite investigation results since
the last public meeting and proposed future activities for the offsite area.
Following the public informational meeting, a conference call between WSP and MDE project team
members was held on June 26, 2015, to discuss potential community involvement activities for the
site. Based on this discussion, WSP and Emerson agreed to provide MDE with a compendium of
public involvement activities to be implemented during future investigation and remediation work.

2.0 Offsite Activities
2.1 Offsite Groundwater Monitoring Program
■
An Offsite Groundwater Monitoring Plan was prepared and submitted to MDE and USEPA Region III
on June 18, 2015. This groundwater monitoring plan described the proposed response action for the
VOC-affected groundwater in the offsite area. The objectives of the monitoring program will be to (1)
gather additional groundwater quality data to evaluate the distribution of site-related VOCs in the
aquifer system hydraulically downgradient of the former Kop-Flex facility, and (2) assess trends in
the VOC concentrations at each monitoring point.
■
The recently installed offsite monitoring wells were sampled the week of June 22, 2015, as requested
by MDE. The analytical results are summarized in Table 3, and historical sampling data for the offsite
wells are provided in Table 4. (A copy of the laboratory report for these samples is provided in
Enclosure A.) No site-related VOCs were detected in the samples from the two shallow wells (MW25-40 and MW-28-45) in the unconfined portion of the Lower Patapsco aquifer. For the deep wells
completed in the semi-confined portion of the Lower Patapsco aquifer, 1,1-dichloroethene (DCE), 1,2dichloroethane, trichloroethene, and 1,4-dioxane were detected at levels above the MDE groundwater
quality criteria in the sample from well MW-25-130, which is located in the northeastern portion of the
Harmans Woods neighborhood south of the Maryland Route 100 (Table 3 and Figure 5). Lower
concentrations of these site-related VOCs were present in the sample from the deeper well (MW-25192) at this location, which is consistent with the vertical distribution of constituents determined from
previous groundwater investigations. The sampling data for the deep monitoring wells located further
south of MW-25 indicated non-detect to very low concentrations of the site-related VOCs (Figure 5).
The 1,1-DCE concentration in the sample from well MW-28-210 (12.8 µg/l) is slightly above the
applicable groundwater quality standard. In addition, 1,4-dioxane was detected at a concentration of
6.8 µg/l the sample from the deeper of the two wells at the MW-33 location (MW-33-295) (Table 1).
The groundwater sample from the shallower of the two wells at the MW-33 location had non-detect
levels for the site-related VOCs.
2.2 Residential Well Sampling
■
On June 22, 2015, a water sample was collected from the potable well at 763 Donaldson Avenue,
which is located in the Phase 3 sampling area. This well had not been previously sampled due to the
inability to schedule a sampling appointment with the homeowner.
The analytical results for this residential well sample were received on July 9, 2015. Copies of the
laboratory reporting sheets for this sample are included in the certified analytical report provided in
Enclosure B. No site-related VOCs were detected above the applicable groundwater comparative
criteria in the well sample.
