Status – No additional action required to since completion in 2015
Follow all setback requirements for new potential contaminant sources within the
IWMZ. Continuously monitored and followed
Implement the WHP Measures and Findings in the IWMZ inventory and requirements of
the Sanitary Survey Report. 2016 – 2024 Monitoring and followed
Contact the MDH Planner if changes to the locations or construction of potential
contaminant sources are proposed in the IWMZ. Status – Continuously monitored
2016 – 2024 No changes to locations or construction of potential contaminant sources
proposed in the IWMZ.
Land Use Controls and Management Action Items:
The City will explore options to strengthen language in the cross-connection ordinance.
Status Complete - Cross-connection ordinance in place and properly regulate cross
connections. The City maintains and enforces a backflow prevention program.
The City will evaluate their zoning ordinances and make necessary changes to
strengthen controls in regards to properly managing wells and storage tanks within City
limits and the Drinking Water Supply Management Areas (DWSMA).
Status Complete – Zoning ordinances in place & properly support management areas.
Data Collection Action Items:
Work in cooperation with MDH, collect tritium sample from the public supply wells as
directed by MDH.
Status – MDH has not requested tritium sampling during this Plan cycle as it is in a 10-
year cycle; sampling and anticipated in 2024. The aquifer vulnerability score is low
based on previous sampling.
Incorporate instrumentation within Well#6 in order to provide more detailed water
quantity information.
Status Complete – equipment was installed for level monitoring during 2016 well
inspection and maintenance.
Cooperate with MDH to ensure the City manages radium levels providing safe drinking
water to their residents.
Operations Staff conducts routine monitoring per MDH direction supporting safe
drinking water. A Memorandum of Agreement is in place and reviewed annually for
radium concentrations to mitigate radium levels and maintain water quality within set
standards.
Well 1 - high radium concentrations, removed from service and sealed in 2019.
Well 2 – high radium concentrations, only used for emergency purposes and included in
memorandum of agreement with the MDH.
Well 8 – high radium concentrations, operated minimally to ensure meeting safe
drinking water standards, included within memorandum of agreement.
Well 9 – installed in 2020 to support capacity and water quality. A Water Master Plan
was completed in 2019 adopted by Council in 2020.
Well 10 – installed in 2023 to support capacity and water quality.
Well 11 – Installed to further support capacity and water quality. Water Treatment
construction has started for existing Wellhouse 4, designing for Wellhouse 3 &
planned for a new South-Central location. The system interconnect is
established with extensions planned to benefit system risk & resilience practices.
The City will contact the MDH Hydrologist and ask for their assistance in helping to
select an alternative site for drilling a new public supply well in the case one is needed
in the future. The City can apply for MDH grants to help offset the cost of exploratory
drilling and water quality sampling etc.
Status – Operations and Engineering review water supply needs on an annual basis to
ensure demands are met. Capital planning is preparing funding for additional water
storage and water production capacity to meet community growth.
Irrigation Restrictions have been implemented and educational water conservation
material is available on the City website and reminded within Utility Billings.

Potential Contaminant Source Management Action Items:
The City will apply for a grant via MDH to secure funds to seal any unused, unsealed
wells located within the DWSMAs. If funding is not available via MDH, the City will work
cooperatively with local units of governments to provide as much cost share as possible
to help seal the wells. The City will request MDH Well Management assistance with
locating wells on properties where the City feels there might be unused unsealed wells.
Status – no unused unsealed wells identified at this time. As new developments are
considered, wells within that property are identified and reviewed for closure or
system separation.
Well 1, with high radium concentrations was removed from service and sealed in 2019.
The Wellhead Protection Team/Manager will continually attempt to locate potential
contaminant sources in the DWSMA. This will be accomplished through direct contact
with landowners and through visual observation as the WHP team travels through the
DWSMA. Status - Ongoing
Cooperate with MDH & DNR Hydrologists as requested to help assess any potential
impacts on the public water supply well(s) or 1.5 miles of the DWSMA boundary. If
impacts are identified cooperatively work with the high capacity well owner, DNR &
MDH Hydrologist to identify & resolve any potential negative impacts. Status – Ongoing
The City will share information regarding the location of any potential Class V well(s)
with the MDH if any well(s) are located within the DWSMA in the future.
Status – In 2018 a potential Class V well was investigated through communication of
the MDH and EPA however found compliant. No Class V wells have been identified by
the WHP team.
The City will contact the MPCA tank program and ask MPCA to update them on the
Leaky Underground Storage Tanks (LUST) site located within their Central DWSMA and
communicate the risk this site may have on the City’s drinking water supply.
Status Complete – communications with MPCA have occurred with official request for
information complete.
It is always difficult to foresee or plan for the future. If a critical issue or potential
contaminant threat becomes an issue in the future for the City, the City will promptly
take actions to prevent this contaminant source from polluting their drinking water
supply. Status – Continuous

the City’s newsletter and direct residents to the City’s website for detailed education
materials.

Website and linked to the MDH “Well Owner’s Handbook - A Consumer’s Guide to Water
Wells in Minnesota Fourth Edition updated January 2014 to provide a reference for well
maintenance and water safety.
Post WHP educational materials on the city website dealing with proper well
management, water conservation etc.
