RE: Bozeman Old City Landfill Characterization
Dear Mr. Flammond,
Water & Environmental Technologies (WET) is pleased to provide this proposal and cost estimate
for further characterization and monitoring of the Bozeman Old City Landfill (Facility). The
proposal was prepared in response to the City of Bozeman’s (City) request for a soil gas and
groundwater investigation to further characterize the extent and magnitude of potential impacts
at and downgradient from the Bozeman Old City Landfill, which is currently listed as a low-
priority Facility on the Montana Department of Environmental Quality (MDEQ) Comprehensive
Environmental Cleanup and Liability Act (CECRA) list.
The proposed scope of work for this investigation was developed based on the findings and
conclusions of the July 2018 Old Bozeman City Landfill Site Assessment report completed by
WET, which presented an environmental data summary and preliminary conceptual site model
(CSM). The sections below outline WET’s proposed scope of work, estimated costs, and
proposed schedule to complete the requested characterization and monitoring activities.
Shawn Kohtz with the City and Josh Vincent and Steve Nicholls with WET met with MDEQ in
March 2019 to discuss this project. During this meeting MDEQ personnel agreed that the initial
monitoring activities could be performed outside of the CECRA/Voluntary Cleanup and
Redevelopment Act (VRCA) program requirements. Depending on the findings reported in the
annual report, further monitoring may have to be completed under the CECRA/VRCA program.
SCOPE OF WORK
The purpose of this investigation is to appropriately characterize the magnitude and extent of
potential soil gas and groundwater impacts associated with the Old Bozeman City Landfill and
develop a more robust assessment of risks to human health and the environment associated
with the landfill.
The proposed scope of work includes the following work tasks:
Task 1. Project management and Corrective Action Plan (CAP) and additional meetings
and/or coordination with the MDEQ CECRA program as needed. The CAP will contain a
summary of monitoring activities, field activities and laboratory analyses to be performed,
however it will be completed outside of the full scope of CECRA program requirements.
DocuSign Envelope ID: AAE6E834-B97B-4DF6-9691-1D6E91C5737B

Task 2. Configure a project database which will contain historical data compiled by WET
for the 2018 site assessment and all future data that will be collected as part of this
characterization.
Task 3. Install two new groundwater monitoring wells, sample drill cuttings, repair two
existing groundwater monitoring wells, and install surface monuments on two existing
wells and soil gas points (SGPs) to promote their suitability for long term monitoring.
Task 4. Monitor new and existing Old Bozeman City Landfill groundwater monitoring
wells and SGPs. All soil gas and groundwater samples will be submitted to an analytical
laboratory for analysis of volatile organic compounds (VOCs).
Task 5. Prepare an Annual Report including a description of all monitoring activities
conducted the previous year, the data collected, an updated site conceptual model and
risk assessment, as well as recommendations for long-term monitoring or corrective
action, if necessary.
Task 1. Project Management / Corrective Action Plan
Duties associated with this task include meetings and project updates with City personnel;
coordination with MDEQ CECRA personnel, scheduling of field work and project reporting;
coordination with area landowner(s) and other project stakeholders; communicating with
subcontractors and vendors; and monitoring the project budget and deliverables. WET
personnel will provide status reports to City of Bozeman on an as-needed basis, and with each
invoice submitted.
The first project deliverable will be a CAP which will include a description of all activities
associated with the characterization, including sampling activities, wells installation/repairs,
reinforcement of existing soil vapor monitoring stations, laboratory analyses. The CAP will be
completed before initiating subsequent characterization work.
Task 2. Data Management
Historical environmental data will be moved to a project specific database in Microsoft Access
format. As long-term monitoring progresses, the database will be kept up to date with newly
installed monitoring site locations, field parameters, and laboratory analytical data for
groundwater, soil, and soil gas samples. The database can be tailored to make future data entry
user friendly. The database will also feature several basic output options to generate reports of
field data and laboratory analytical results.
WET proposes to enter groundwater and soil vapor sampling field data electronically in the field
using ArcGIS Online Survey 123 forms. During and after data entry in the field, the data is initially
stored electronically in the cloud. After conclusion of the sampling event, the database will sync
with the cloud-based Survey 123 data and update automatically with the newly collected data.
Backup field forms will be available for redundancy as needed, and the database will have a data
entry form to manually enter or change field data if needed. A copy of the database will be
provided to the City of Bozeman with the Annual Report and more frequently, upon request.
Task 3. Monitoring Stations - Repair, Reinforcement and Installation
Figure 1 shows the locations of existing monitoring wells and soil vapor stations. Well MW-1 will
be repaired and well 12 will be fitted with a locking well cap. Additional protection (manhole cover

and concrete at the surface) will be added to MW-1, MW-2 and soil gas points sites VW-1 and VW-
2.
WET will install two additional groundwater monitoring wells (MW-3 and MW-4) to a depth of
approximately 10-20 feet. The proposed locations are included on Figure 1. These locations may
be adjusted based on proposed or completed development activities in the vicinity. The wells will
be constructed with two-inch diameter polyvinyl chloride (PVC) casing and 0.020-inch factory
slotted screen installed across the groundwater table. The annular space between the PVC well
and the boring wall will be filled with 10-20 silica sand from the terminal depth of the bore to
approximately one foot above the screened interval, and then sealed from this point to
approximately one foot below the surface with hydrated bentonite chips. The remaining one foot of
annular space will be filled with native backfill from the surrounding ground surface. These wells
will be completed with aboveground monuments with locking caps.
Task 4. Monitoring Activities
Following monitoring well installation, WET will sample the nine existing and two new monitoring
wells, as well as the irrigation well adjacent to the East Gallatin Recreation Area facilities building to
assess current groundwater quality. Quality Assurance / Quality Control samples will be collected
at a frequency specified in the CAP. Monitoring will be conducted using low-flow purge and sample
procedures. Groundwater field parameters (temperature, pH, conductivity, dissolved oxygen, and
oxidation reduction potential) will be measured during purging, and once parameters stabilize, a
groundwater sample will be collected in laboratory-supplied bottles and analyzed for VOCs.
During the first quarterly sampling event, additional field activities will include soil vapor sampling
of VW-1 and VW-2 and survey of new/repaired wells Soil gas samples will be collected using
six-liter summa canisters and analyzed for VOCs.
After the initial monitoring event, WET proposes additional quarterly groundwater and soil vapor
sampling for a period of one year.
Task 5. Project Reporting
After one year, and collection of four quarters of environmental data, WET will prepare an Annual
Report, which will include:
A discussion of drilling and monitoring activities;
Logs of newly installed groundwater monitoring wells;
Tabulated groundwater and soil gas monitoring data;
Laboratory analytical reports;
Photographs documenting field activities;
A summary of the findings including tabulated analytical data, maps of sample and well
locations;
An updated conceptual site model and assessment of risks to human health and the
environment, and
Recommendations for further monitoring / corrective actions.
