AGENDA ITEM DETAILS
RECOMMENDATION:
City Staff and the Wellhead Protection Team provide recommendation for acceptance of the Wellhead
Protection Plan for submittal to the Minnesota Department of Health for approval by adopting
resolution 2016-66.
ARE YOU SEEKING APPROVAL OF A CONTRACT?
No
IS A PUBLIC HEARING REQUIRED?
Yes
BACKGROUND/JUSTIFICATION:
The Minnesota Department of Health (MDH) requires communities to reevaluate their Wellhead
Protection Plan (WHPP) every 10 years. Staff is requesting adoption of the draft plan for MDH final
approval.
Part 1 of the Plan Source Water Vulnerability, was completed in 2015 by Barr Engineering using
geological modeling and water production estimates showing an overall status of not vulnerable with
moderate vulnerability within the central Drinking Water Supply Management Area (DWSMA).
Part 2 of the Plan has been drafted with assistance of Minnesota Rural Water Association (MRWA),
Hakanson Anderson Inc. and the Wellhead Protection team including information pertaining to:
1. Inventory of potential contaminant sources within the DWSMA
2. Data considered in this portion of the plan
3. Issues, problems, and concerns within the DWSMA
4. Goals, objectives, and action strategies to address the issues and concerns within the
DWSMA
5. A Plan evaluation strategy
6. A contingency strategy in the event of water system disruption.
Plan implementation includes education, data collection, source and land use management, contingency
strategies, reporting and evaluation.
The draft WHPP was provided to Wright County Officials, City of Rogers, City of Dayton, MRWA and
MDH for a 60 day review and comment period ending on July 15" 2016 (MN Wellhead Protection Rule
4720.5350, subpart 1).
Wright Soil & Water Conservation District (WSWCD) was the only commenting party; requesting minor
clerical changes, a reminder of the importance and offer of assistance to provide farming Best
Management Practices (BMP) within DWSMA's, encouragement of radium testing in residential wells
and recommended a memorandum to neighboring communities within the WHP area for land use and
spill incidence.
In response to comments from Wright Soil & Water Conservation District; page numbers were
amended, the health concern regarding radium is addressed by a MDH Agreement, farming BMP's is not
an impacting factor to our sources however always appreciate assistance, and anticipate further
communication with neighboring communities within our WHP area.
A Public Hearing was scheduled consistent with the Wellhead Protection Rule (4720.5330, subpart 7) on
July 25, 2016 at 7:00 pm for plan adoption.

MEMORANDUM OF AGREEMENT
Contaminant: Radium 226 and 228
Otsego Public Water System
This Memorandum of Agreement (hereinafter "Agreement", by and between the City of Otsego,
1860026 (hereinafter "System"), rd the Minnesota Department of Health (hereinafter "MDH")
hecnmes effective on the date slaned on behalf of the MDH.
I. Authorities and Findings
A. Pursuant to the Safe Drinking ater Act, Minnesota Statutes, sections 144.381 to 144.387, and
Minnesota Rules chapter 4720, the MDH enforces the National Primary Drinking Water Regulations, In
Minnesota Rules, part 4720,0350 the MDH has adopted the federal National Primary Drinking Water
Regulations, 40 CFR, Part 141, by reference. 40 CFR, section 141.66(b), establishes the maximum
contaminant level (MCL) for Radium 226 and 228.
B. The System seeks to remain in compliance with the National Primary Drinking Water Regulations
because the System's water supp y exceeds the MCL of 5.4 picocuries per liter (pCi/L) for Combined
Radium 226/228. Through this A. reement, the parties seek to keep the System in compliance with the
National Primary Drinking Water egulations.
il. Corrective Actions
It is agreed between the System nd MDH that until the corrective actions set forth below have been
implemented and compliance with the MCL for Combined Radium has been accomplished, the System
shall meet the following conditions for the entry points known as Combined Discharge 1 and Combined
Discharge 3.
1. The System shall monitor the Combined Discharge 1 and 3. entry point bi-annually for radium and
gross alpha concentration )S. The entry point samples shall be collected from the source of water
after treatment. All sampl;s will be collected by the System's public water supply operator and
sent to the MDH Laborato� y for analysis. The MDH will supply the sampling kits and pay for the
cost of analyzing the samples; however, the System is responsible for the cost of shipping the
samples to the laboratory
2. Well 1 and Well 2 will onl ( be used in an emergency situation (such as fire protection).
3. The System shall monitor the Well 3 and Well 8 source points annually for radium and gross
alpha concentrations. The radium concentrations from these measurements will be used when
updating future MOAs. Tf}ese samples shall be collected from the source water before
treatment and before water is combined via Combined Discharge 3. All samples will be collected
by the System's public wa der supply operator and sent to the MDH Laboratory for analysis. The
MDH will supply the sampl)ing idts and pay for the cost of analyzing the samples; however, the
System Is responsible fort I he cost of shipping the samples to the laboratory.
4. Well 3 and Well 8 are connected via combined discharge at the pump_house. These two wells
shall meet the following e uation on an annual basis with well volume measurements taken on a
daily basis;
Otsego

Page 2
[(V3) (Ras) + (Vs)(Ras)] / [V3+V8] < MCL with 10 percent factor of safety
where:
V3 = Volume produced by Well 3
Vs= Volume produced by Well 8
Rai =Radium 226/228 concentration at Well 3
Ras= Radium 226/228 concentration at Well 8
Well 3 (2.5 pCi/L) and Well 8 (12.9 pCi/L), have an expected combined radium 226/228
concentration of 9.43 pCi/L with flow rates of 700 gpm at Well 3 and 1,400 gpm at Well 8 for a
total of 2100 gpm. Based on the design of the system and the average concentrations of radium
226/228 present in the wells the following conditions will need to be achieved:
a) Well 3 will be the only producing well from January 1 through April 14, 2016, and
October 16 through December 31, 2016.
b) MDH requires Well 8 contribute no more than 45 percent of the total volume of water
during combined use.
Both conditions a) and b) based on measured values of radium concentration will
result in an annual combined radium 226/228 average concentration of 4.9 pCi/L or
less.
5. If the use of Well 1, Well 2, Well 3, Well 6 and Well 8 are not operated per the requirements
above from April 15th 2016 through April 14th, 2017, the System must immediately notify MDH
and the consuming public of the Combined Radium 226/228 exceedance. Public notification
must then continue on a quarterly basis as required by MDH, and documentation must be
provided to MDH within 10 days of each public notification.
6. Take corrective action according to the schedule as follows:
Action Required:
Complete no later than:
A. Collect Gross Alpha and Combined Radium samples
In Quarter 2 and Quarter 3, 2016
at the Combined Discharge 1 and 3
B. Collect Gross Alpha and Combined Radium samples
In Quarter 3, 2016
from Well 3, Well 6 and Well 8 annually
C. Memorandum of Agreement will be updated
March 31, 2017
annually
7. The System will continue to notify the consuming public annually in the Consumer Confidence
Report.

The City of Otsego should be aware that the page numbers listed in the table of contents
does not match the location of each section. There is a 2 page discrepancy.
There is a health concern for radium in three of the eight wells. These three wells are
currently only used for emergency status until a resolution can be reached. However, it may be
beneficial for the city to learn about private wells in the area that may also have radium
contamination. As the SWCD conducts groundwater monitoring throughout the county it could
encourage any residents in and near the wellhead protection area to consider testing for radium.
In addition, the SWCD could ask these homeowners to share their results with the city. There are
some privacy issues associated with this project.
The DWSMA's in Otsego do have agricultural land ranging from 17.96% (Otsego 7) to
63.37% (Otsego SE). Farms are a source of non -point contamination, the Wright SWCD could
assist in encouraging BMP's to be utilized on these farms or informing the landowners of the
importance of the land to the City of Otsego. However, all of the drinking water wells for the
City of Otsego are considered not vulnerable, so the potential for surface contamination from a
farm is rather low. The WPPH does note a small area in Otsego East DWSMA that has moderate
vulnerability. If the landuse in the moderately vulnerable area includes agriculture then the
importance of farming BMP's grows.
Otsego expresses a concern of the land within their wellhead protection area that lies in
Rogers and Dayton. If possible we recommend a written memorandum of understand or other like
document indicating partnership between Otsego and corresponding towns. Such a document
could assist in communication of changes to the land area or incidents that occur within the well
head protection area such as spill.
Yours in conservation,
