RECOMMENDATION.
City staff recommends authorization to obtain quotes for completion of a study to determine and
update the limits of the Drinking Water Supply Management Areas within the City of Otsego.
ARE YOU SEEKING APPROVAL OF A CONTRACT? IS A PUBLIC HEARING REQUIRED?
No No
BACKGROUND/JUSTIFICATION:
Every 10 years the Minnesota Department of Health (MDH) requires municipalities with public water
systems to update and amend their Well Head Protection plan. As part of that, any changes to the
water supply sources must be reviewed and Drinking Water Supply Management Areas (DWSMA)
boundaries set. These DWSMAs are used by the City and State to determine the vulnerable areas for
the City's water source. The City and State then manage the land uses in those vulnerable areas. In
o rd e r to do that, geoscie ntists must complete a study. We have prepared a R F P to be sent to 7 or 8
firms capable of completing the study in accordance with the MDH requirements. The MDH has
estimated this will cost $20,000. This should come out of the water fund.

Request for Proposal (RFP)
City of Otsego
hift-odtiction
The City of Otsego requests proposals from qualified consulting firms to provide expertise related to
wellhead protection activities. To be qualified, the person who is responsible for managing the work
identified in this RFP must be licensed by the State of Minnesota under provisions of Minnesota
Statutes 326.02, pertaining to work conducted by a geoscientist. This expertise will be directed
towards assisting the City in fulfilling the requirements of Minnesota Rules, parts 4720.5100 to
4720. 5590, with respect to conducting wellhead protection area delineations, completing vulnerability
assessments, and meeting associated reporting requirements. The result of this RFP will be a contract
for technical services as described below.
Pin-pose/Anticipated Results
The objectives of the work activities are to complete the wellhead protection area (WHPA) delineation,
c an assessment of well and aquifer vulnerability, and associated reporting requirements in order to meet
the wellhead protection rule requirements (NIR, pails 4720.5100 to 4720.5590) for wellhead
protection.

2.0, Delineate Wellhead Protection Area (WHPA)
2.1. Method Scoping. Assess available geologic and hydrogeologic data to determine the level
of effort required to meet the wellhead rules for WHPA delineation. The Mituiesota
wellhead rule (MR 4720.5510) requires that the following criteria be evaluated and
considered as part of the method used to make the delineation:
$ time of travel
$ flow boundaries
$ daily volume
$ groundwater flow field
$ aquifer tralismissivity
CONTRACTORS should use data assembled in Tasks 1.1 through 1.4 to make the
evaluation of these criteria. This evaluation will lielp to define the conceptual model for the
aquifer(s) used by the city wells and will serve to guide the WHPA delineation efforts. A
preliminary review of these criteria was performed at the time of the first scoping meeting
with Joy Loughry from the Minnesota Department of Health. The scoping decision notice
(attached) defines how these criteria must be addressed. For the purpose of responding to
this RFP, the City staff, in consultation with the Minnesota Department of Health, have
identified that the delineation method must address the following items:
11-1111tiple Pumping wells and their pumping effects on the capture zones of other
wells;
changes in the base elevation of the aquifer(s) used by the city wells;
o in -homogeneities resulting from changes in geological conditions;
0 variable rates of recharge to the aquiter(s) used by the city wells; and
0 influences of local streams and the Mississippi Crow Rivers on the groundwater flow
field.
2.2. Pre -Delineation Meeting. After completing all tasks under Section 2. 1, CONTRACTOR
shall ineet with staff from the City and MDH to discuss the delineation criteria, the
conceptual model, and the WHPA delineation method.
Rev. 6: 'November 12, 1999; edited March 2008 3
2.3. Delineation of the WHPA. Using the method identified in the previous subtasks, delineate
the wellhead protection area for each of the following city wells:
A time -of -travel of one and ten years will be used to define WHPA boundaries for each well
listed. All of these time -of -travel zones must be shown on maps in the project deliverables.
The designated WH As for city wells must include the surface water drainages in the up -
gradient direction of groundwater flow that may recharge the unconfined aquifer used by
these wells.
2.4. Delineate the Drinking Water Supply Management Area (DWSMA) using the boundary
definitions contained in the wellhead protection rules (MR 4720.5 100, subp. 13).
3.0. Conduct Vulnerability Assessment
The vulnerability assessinent must be done in accordance with the wellhead protection rules
(MR 4720.5 210) for each of the wells and aquifers in the area of the DWSMAs delineated for the
City. The well vulnerability assessment conducted by M to phase a well into the WHP
program must be reviewed in light of other data collected for the WHPA delineation to determine
whether it should be revised. Also, geologic data collected for the WHPA delineation and
groundwater chemistry data collected to satisfy the requirements of the scoping decision prepared
by M must be used to prepare an aquifer vulnerability assessment of the entire DWSMA.
4.0. DelineationNulnerability Reporting/Deliverables
4.1. Draft Report. A draft report will be prepared and submitted to M to satisfy the wellhead
Protection reporting requirements for WHPA delineations and vulnerability assessments. A
key objective of the report is to provide sufficient documentation to meet wellhead
protection rule requirements for SDH review and approval (MIS 4720.533[0 for the WHPA
delineation and vulnerability assessment.
4.1.1. The report will describe how the data elements listed in the scoping notice prepared
by M were addressed in conducting the delineations and assessments,, and the
technical approach used to inake the analysis of each specified data element.
Accordingly, the report must describe, for each of the wells, the following details:
1) the hydrogeologic setting used to characterize the aquifer, 2) the five delineation
criteria, 3) the delineation inethod used, 4) the delineation results, 5) data collected
and used other than those provided by MDH, and 6) a copy of the calculations
perforn-ied when a computer model is used, the electronic data input and Solution
files).
4.1.2. Documentation of the VUlnerability of the DWSMA inust:
� identify the method used;
$ describe the geologic conditions throughout the DWSMA, fioni the land surface
to the base of the aquifer and adjacent geologic materials;
$ contain the data elements collected and used; and
$ contain the maps, diagrams, reports, studies, and tables used to prepare the
DWSMA vulnerability assessment.

Rev. 6: November 12, 1999; edited March 2008
4.1.3. All geographic information must. be presented on a stable base material or in
electronic form. If this information is to be submitted electronically,
CONTR-ACTON must use ARCGIS formats using UTM, Zone 15, north -meters
(NAD 83 Datum).
4.1.4. 3 paper and electronic copies of the draft report will be required.
4.2. Final Report. The draft report will be updated to respond to comments made by the City and
M staff. 3 paper and electronic copies of thefinal r will be required.
4.3. Project Work Products
4.3.1. Model Input Sets. The modeling input files, as revised to meet the terms of this
project and the MIH wellhead protection rules, will be a key component of the
project deliverables,
4.3.2. Supporting Data Files. Project -specific data files that define aquifer
geonietry/hydraclic characteristics and from which model input files are created
(insofar as the model is modified from an existing model) must be presented
digitally, preferably in an ARCV1EW or ARCANFO format. Model input should be
in the form of:
1) polygons (e.g., representing zones of like hydraulic conductivity, unit base
elevation, recharge values, etc.);
2) lines, (e.g., defining locations of various hydratilic boundary conditions), and
3) point data (e.g., wells).
Metadata aimotation must accompany these files. The metadata documentation files
need not be elaborate or lengthy but must, ata mininiuni, contain the following:
1) description of feature being documented (e.g., stream location and elevation,
bedrock elevation);
2) data source (e.g., USGS q"ad sheets, IVIES bedrock geology IS cover);
3) date of the source s), and
4) areas where the model input differs from referenced source s),
4.3.3. Wellhead Protection Area Delineations. The one and ten-year time -of -travel WHPA
delineations must be delivered in such a way that a minimum of 20 streamline traces
are defined (using X, y, z, time, line id, and well unique number data attributes) in an
ASCII or an ARCGIS compatible electronic file -format. Geographic coordinates for
the city well s) listed above must be those provided by the MDH.
5.o, Meetings
During the course of this project a series of formal and informal meetings are expected (assume 4
ineetings @ 2 hours each). Inform al meetings with City staff will be necessary on an occasional
(approximately once every four to six weeks) basis while the project is active. These meetings
will take place at the City offices and will serve as progress reports on the techiiical activities. It
may be possible to hold these meetings via telephone.
