SCOPE OF SERVICES
CITY OF BOZEMAN, MONTANA
WATER QUALITY TECHNICAL ASSISTANCE
BACKGROUND
The City of Bozeman (City) has been engaged in activities related to the water quality of the
East Gallatin River (EGR) for a number of years. These activities have consisted of sampling
work to characterize longitudinal trends in nutrient concentrations, algae concentrations, river
flow, and aquatic life from upstream of the Water Reclamation Facility (WRF) to the EGR's
confluence with the main stem of the Gallatin River. Sampling work to characterize trends in
aquatic life in the form of benthic macroinvertebrates (BMI) was last conducted in 2015. The
City would like to resample for BMI this summer along the EGR to characterize the current
trends in aquatic life.
BMI samples would be collected at the nine sites previously sampled for BMI. These sites
consist of Sites A, B, C, D, F, G, H, I, and J. Collecting BMI samples along the length of the
EGR will provide the City with additional biological information to present to the Montana
Department of Environmental Quality (MDEQ). This information could supplement the site
specific water quality variance being developed by the City.
Several other water quality parameters would also be collected at each site. These additional
parameters would supplement the BMI data, and would consist of instantaneous water quality
measurements, flow measurements, and habitat surveys.
OBJECTIVES
1. Develop a sampling and Analysis Plan (SAP) for summer 2020 BMI collection along the
East Gallatin River. Submit to DEQ for approval.
2. Collect BMI samples and instantaneous water quality measurements at the nine EGR
sites previously sampled for BMI in 2014 and 2015. These sites consist of Sites A, B, C,
D, F, G, H, I, and J. Develop O/E predictor variables for use by the lab during BMI
analysis. Submit BMI results to MT-eWQX database.
SCOPE OF SERVICES
This scope of services is for the Consultant to assist the City through technical assistance
activities related to EGR water quality. The proposed scope of Consultant services are identified
in the following tasks. Consultant will commence with services upon written notice to proceed
with the selected tasks. Schedule will be determined at the time of notice to proceed.

Task 1 . Develop SAP for BMA Sampling
Objective and Approach
This work will include the preparation of a Sampling and Analysis Plan (SAP) and Quality
Assurance Project Plan (QAPP) for the sampling of BMI along the East Gallatin River. A health
and safety plan for the sampling work will also be developed. Details to be developed and
incorporated into the SAP and QAPP include:
• Details on where samples will be collected
• Details on what data parameters will be collected
• Details on when sampling will occur
• Details on field sampling methods, i.e., instruments, techniques, volumes, sample
handling procedures, preservation and holding times
• Details on laboratory analysis method
o Identification of who will conduct the analysis
o Identification of methods and procedures
o Identification of reporting limits
• Details on quality assurance and quality control along with record keeping and reporting
requirements
The draft SAP and QAPP will be submitted to the City for review and the draft SAP and QAPP
will be revised if needed. The revised SAP and QAPP will then be submitted to MDEQ for
review.
0]iuilII )ial )�].
• City reviews and approves the SAP and QAPP.
• MDEQ reviews and approves the SAP and QAPP.
o Significant additional negotiations with MDEQ are not included in this initial work
plan.
• Reviews will be completed within three weeks of submittal of drafts. Implementation of
the SAP and QAPP for data collection in the summer of 2020 is dependent on timely
reviews.
• No sampling is planned in this task.
• No analysis or modeling is planned in this task.
Deliverables
• Draft SAP and QAPP documents submitted electronically to the City for review.
• Draft SAP and QAPP documents submitted electronically to MDEQ for review.
• Final SAP and QAPP documents submitted to City and MDEQ.

Task 2. Sampling BMI along East Gallatin River
Objective and Approach
This task will include the labor and budget resources for collecting BMI samples and other water
quality data along the EGR at all the sites previously sampled for BMI in 2015. A single
sampling event is assumed for the collection of BMI samples at these sites, which are
preliminarily outlined in Table 1 for planning purposes. A map of the sites is shown in Figure 1.
Table 1.Sampling Sites
A Just upstream of Cherry River Fishing Access site 45.7150' -111.04639*
B -0.3 stream miles upstream of Bozeman WRF outfall 45.72568' -111.06469*
C -0.9 stream miles downstream of the Bozeman WRF outfall 45.7284° -111.0720*
D -0.3 stream miles downstream of the Riverside Water&Sewer District ponds 45.7363' -111.07105*
F Lower third of river reach 45.76698° -111.0968*
G Upstream of confluence with Hyalite Creek 45.7888' -111.1195*
H Just upstream of the Dry Creek irrigation withdrawal 45.83059' -111.14617°

Figure 1.Map of Sampling Sites
Benthic macroinvertebrate samples will be collected using a reach-wide site layout as outlined
in Montana DEQ's medium sized rivers protocol. At each site, samples will be collected
longitudinally (i.e., following the river course) along a reach at least 150 m long. One duplicate
BMI field sample will be collected at one of the sites. These BMI samples will be sent to Rithron
Associates for analysis. HDR will supply the O/E predictor variables for use by the lab.
Additionally, at each sampling site the following supplemental physical habitat and water quality
measurements will be taken:
• Instantaneous measurement of DO, pH, conductivity and temperature
• Flow rate of sampling site
• Width and depth measurements of the sampling site cross sections
• Channel and riparian characterization
• Aquatic Plant Visual Assessment

Assumptions
• Sampling will be consistent with the approved SAP, but the expected sites are shown in
Figure 1 and Table 1 for planning purposes.
• One sampling event will be conducted during low flow conditions at a time agreed upon by
the City and HDR.
• HDR will supply O/E predictor variables to the lab for BMI analysis.
• No technical memorandum discussing results will be prepared.
Deliverables
• Instantaneous water quality and habitat data tables
• BMI taxonomic data files (Lab Data)
• BMI calculated metrics and O/E results (Lab Data)
Task 3. BMI and Water Quality Data Analysis
Objective and Approach
BMI data will be evaluated alongside physical and chemical variables characterized in the field
to gain insight into the most probable stressors to the BMI community in the EGR. The BMI
community will be compared among the sampling sites in terms of taxonomic similarity,
community metrics, and comparison to regional biocriteria. The BMI results will be compared to
physical and chemical variables that were measured or observed in the field. The comparisons
will be made with pairwise correlations, bivariate plots, and longitudinal trends. The findings will
include the characterization of the BMI community among sites and identification of potential
physical and chemical stressors to the BMI community. The other water quality parameters
collected will also be summarized and organized into a data summary report.
All collected data will be submitted to the MT-eWQX water quality database.
Deliverables
• A technical memorandum discussing the findings and an organized Excel data set.
• Receipt showing that BMI data has been uploaded to the MT-eWQX database.
