1.0 INTRODUCTION
On behalf of Windham & Windsor Housing Trust (WWHT), Environmental Compliance Services, Inc.
(ECS) has prepared this Operations and Maintenance (O&M) Summary Report for the subslab
depressurization system (SDS) currently operating at 68 Birge Street in Brattleboro, Vermont (i.e., the
Site). The operational monitoring this period was completed in November 2013 and May 2014.
Maintenance activities have been completed by WWHT on a monthly basis.
The SDS was installed as part of corrective actions conducted at the Site that included the excavation of
impacted soil, placement of engineering controls and the filing of a Notice to the Land Records. Upon
completion of construction, the SDS began operating in February 2008 to provide a negative pressure
beneath the building to mitigate risks associated with exposure to potential vapor intrusion from
volatilization of residual chlorinated solvents (i.e., mainly trichloroethene-TCE) that remain in soil
beneath the subslab.
This O&M Summary Report is being submitted as part of the requirements of the 2007 Corrective Action
Plan (CAP). The O&M is conducted to ensure that the SDS is maintaining the performance goals
established in the CAP. Since the system was not designed to remediate TCE impacted soil detected
beneath the subslab, the performance goals for the system are to maintain a negative pressure of at least
0.02 inches of water column (in. wc.) beneath the foot print of the building to prevent vapor intrusion. To
assure that a negative pressure is constantly maintained, the system operates on a continual basis for 24-
hours a day.
Additionally, since it was not technically feasible or cost effective to remove all impacted soil from the
Site, engineering controls were constructed to prevent the risk of exposure to residual impacted soil
located outside the building footprint. The engineering controls consist primarily of caps constructed of
soil, asphalt and polyethylene sheeting, which were designed to reduce the risk of direct contact and
inhalation exposure to the residual impacted soil. A Soil Management Plan (SMP) was developed to
protect the integrity of these engineering controls and describes procedures to follow when subsurface
work is conducted at the Site.
A copy of the SMP is located in the maintenance supervisor’s office at the Site and is readily available for
review. As recommended in the SMP, WWHT will provide annual reports to Vermont Department of
Environmental Conservation (DEC) on the conditions of the engineering controls. In addition, this O&M
Report provides information on the conditions of the controls (i.e., caps) based on visual observations
during O&M service visits for the SDS.

2.0 OPERATIONS AND MAINTENANCE OF SDS
This section of the O&M Summary Report provides a brief overview of the work completed to ensure the
system is operating efficiently and that performance goals identified in the CAP are maintained. A layout
of the SDS is provided as Figure 1.
2.1 System Monitoring
As part of the system operations and maintenance program, ECS monitors and records:
System vacuum and flow rate;
Vacuum and flow rate at each extraction well; and
System effluent and off-gas treatment screening utilizing a photoionization detector (PID).
System monitoring was completed on November 19, 2013 and May 6, 2014. The data collected
during these monitoring events was tabulated and is summarized in Table 1A and Table 1B. As
shown on Table 1B the system continues to operate with an air flow rate 5,900 feet per minute (fpm)
at a vacuum of 40 inches of water column (in. wc.) at the system influent.
As part of the O&M, ECS has been monitoring the sight-glass in the knockout tank for buildup of
condensation. No liquid was drained during the O&M visits completed during this reporting period.
2.2 System Influent and Effluent Sampling
The SVE system was equipped with a 400 pound drum (Model-Tetrasolve VR-400) of vapor phase
granular activated carbon (GAC) to treat air/vapors before discharging to the atmosphere. ECS
collected an air sample at the effluent (i.e., post-carbon treatment) on both November 19, 2013 and
May 6, 2014, to monitor for residual TCE concentrations being captured beneath the subslab and
ensure that the GAC continued to function within design parameters. No influent sample (i.e.,
collected pre-carbon treatment) was collected this reporting period. The effluent samples were
collected in a summa canister and submitted to Spectrum Analytical of Agawam, Massachusetts, for
analysis of chlorinated solvents via EPA Method TO-15.
A low concentration of chloromethane was observed in the effluent sample collected in November
2013. Laboratory analytical results indicate that chlorinated solvents were not present in the effluent
sample in excess of the laboratory detection limit during the May 2014 sampling event; however, low
concentrations of volatile organic compounds were observed during both sampling events. The
absence of chlorinated solvents, and particularly TCE, is indicative of proper system function. Based
on the observed breakthrough of volatile organic compounds from the vapor phase GAC unit, the
GAC unit was replaced on June 25, 2014. Copies of the laboratory analytical reports are provided in
Attachment I.
2.3 Assessment of Negative Pressure beneath Subslab
During the November 2013 and May 2014 O&M activities, ECS was on-site to assess the efficiency
of the SDS for maintaining negative pressure beneath the footprint of the building. ECS collected
vacuum measurements at the nine monitoring points located throughout the interior portion of the
Operations and Maintenance Summary Report ECS Project #04-206909.00

building. The locations of the monitoring points are depicted on Figure 1. Table 2.1, below,
summarizes the vacuum readings recorded at the nine monitoring points. Negative pressure was
recorded at the nine monitoring points at levels ranging from 0.011 inches of water column (in. wc.)
to 1.5 in. wc.

As concluded in previous reports, the placement of the extraction wells and trenching is shown to
influence the propagation of vacuum. However, based on the operational evaluation data collected in
May 2012, it is safe to continue to assume that at least a 28-foot ROI is occurring across each of the
extraction wells, and thus providing a negative pressure beneath the subslab of the building. The 28-
foot ROI is depicted on Figure 1. This operational evaluation is scheduled to be repeated in the fall.

3.0 CONCLUSIONS AND RECOMMENDATIONS
Based on the data collected during the O&M visits completed in November 2013 and May 2014, ECS
is of the opinion that the SDS is continuing to operate at its performance goal, maintaining an induced
vacuum averaging greater than 0.04 in. wc. throughout the footprint of the building. In addition to
O&M activities, ECS also completed a cursory inspection of the asphalt and soil caps and observed
that the caps were all in good condition.
General maintenance of the components of the SDS in the shed is currently being conducted by
WWHT. These practices consist of changing the oil and filter for the blower as recommended by the
manufactures’ specifications. Additional maintenance also includes lubing all grease fitting on the
motor.
Based on the data collected during the November 2013 and May 2014 O&M activities, ECS is of the
opinion that all O&M work should continue on an annual basis with the exception of monitoring the
influent and effluent air at the carbon vessel unit. Monitoring should be completed on a semi-annual
basis to monitor for breakthrough of TCE at the unit. Based on observed low level concentrations of
volatile organic compounds in the effluent from the vapor phase carbon unit, the carbon unit was
replaced on June 25, 2014.

Samples are received and the pressure is recorded from the gauge on the canister. If a canister does not have a gauge, a vacuum gauge
is attached to the valve and pressure is recorded. If the canister is below -10 psig, the can must be pressurized to 0 psig. Tedlar bags
do not have the pressure recorded. The can pressure can be located within this report in the sample header information.
If a Duplicate (DUP) was not requested on the Chain of Custody, method criteria may have been fulfilled with a source sample not of
this Sample Delivery Group.
See below for any non-conformances and issues relating to quality control samples and/or sample analysis/matrix.

Notes and Definitions
RPD Relative Percent Difference
dry Sample results reported on a dry weight basis
NR Not Reported
Laboratory Control Sample (LCS): A known matrix spiked with compound(s) representative of the target analytes, which is used to
document laboratory performance.
Matrix Duplicate: An intra-laboratory split sample which is used to document the precision of a method in a given sample matrix.
Matrix Spike: An aliquot of a sample spiked with a known concentration of target analyte(s). The spiking occurs prior to sample
preparation and analysis. A matrix spike is used to document the bias of a method in a given sample matrix.
Method Blank: An analyte-free matrix to which all reagents are added in the same volumes or proportions as used in sample
processing. The method blank should be carried through the complete sample preparation and analytical procedure. The method blank
is used to document contamination resulting from the analytical process.
Method Detection Limit (MDL): The minimum concentration of a substance that can be measured and reported with 99% confidence
that the analyte concentration is greater than zero and is determined from analysis of a sample in a given matrix type containing the
analyte.
Reportable Detection Limit (RDL): The lowest concentration that can be reliably achieved within specified limits of precision and
accuracy during routine laboratory operating conditions. For many analytes the RDL analyte concentration is selected as the lowest
non-zero standard in the calibration curve. While the RDL is approximately 5 to 10 times the MDL, the RDL for each sample takes
into account the sample volume/weight, extract/digestate volume, cleanup procedures and, if applicable, dry weight correction. Sample
RDLs are highly matrix-dependent.
Surrogate: An organic compound which is similar to the target analyte(s) in chemical composition and behavior in the analytical
process, but which is not normally found in environmental samples. These compounds are spiked into all blanks, standards, and
samples prior to analysis. Percent recoveries are calculated for each surrogate.
Continuing Calibration Verification: The calibration relationship established during the initial calibration must be verified at periodic
intervals. Concentrations, intervals, and criteria are method specific.

CASE NARRATIVE:
Data has been reported to the RDL. This report excludes estimated concentrations detected below the RDL and above the MDL
(J-Flag).
Samples are received and the pressure is recorded from the gauge on the canister. If a canister does not have a gauge, a vacuum gauge
is attached to the valve and pressure is recorded. If the canister is below -10 psig, the can must be pressurized to 0 psig. Tedlar bags
do not have the pressure recorded. The can pressure can be located within this report in the sample header information.
If a Duplicate (DUP) was not requested on the Chain of Custody, method criteria may have been fulfilled with a source sample not of
this Sample Delivery Group.
See below for any non-conformances and issues relating to quality control samples and/or sample analysis/matrix.

RPD Relative Percent Difference
dry Sample results reported on a dry weight basis
NR Not Reported
Laboratory Control Sample (LCS): A known matrix spiked with compound(s) representative of the target analytes, which is used to
document laboratory performance.
Matrix Duplicate: An intra-laboratory split sample which is used to document the precision of a method in a given sample matrix.
Matrix Spike: An aliquot of a sample spiked with a known concentration of target analyte(s). The spiking occurs prior to sample
preparation and analysis. A matrix spike is used to document the bias of a method in a given sample matrix.
Method Blank: An analyte-free matrix to which all reagents are added in the same volumes or proportions as used in sample
processing. The method blank should be carried through the complete sample preparation and analytical procedure. The method blank
is used to document contamination resulting from the analytical process.
Method Detection Limit (MDL): The minimum concentration of a substance that can be measured and reported with 99% confidence
that the analyte concentration is greater than zero and is determined from analysis of a sample in a given matrix type containing the
analyte.
Reportable Detection Limit (RDL): The lowest concentration that can be reliably achieved within specified limits of precision and
accuracy during routine laboratory operating conditions. For many analytes the RDL analyte concentration is selected as the lowest
non-zero standard in the calibration curve. While the RDL is approximately 5 to 10 times the MDL, the RDL for each sample takes
into account the sample volume/weight, extract/digestate volume, cleanup procedures and, if applicable, dry weight correction. Sample
RDLs are highly matrix-dependent.
Surrogate: An organic compound which is similar to the target analyte(s) in chemical composition and behavior in the analytical
process, but which is not normally found in environmental samples. These compounds are spiked into all blanks, standards, and
samples prior to analysis. Percent recoveries are calculated for each surrogate.
Continuing Calibration Verification: The calibration relationship established during the initial calibration must be verified at periodic
intervals. Concentrations, intervals, and criteria are method specific.
