Flowing Well and Boring Special Construction Areas
Now on Well Management Section Web Site
The Well Management Section has added a new feature to our Web site regarding Flowing Well and
Boring Special Construction Areas. This feature can be found in the left margin on the Well
Management Section’s home Web page, or at: www.health.state.mn.us/divs/eh/wells/flowing. One
Flowing Well and Boring Special Construction Area has been designated to date, and is located in
Hubbard County, along the southeast shore of Kabekona Lake and the south shore of Benedict Lake.
Under Minnesota Rules, part 4725.3450, subpart 2, item A (3), the Commissioner of Health can
designate a Flowing Well and Boring Special Construction Area “. . . where the use of standard
construction techniques have resulted in uncontrolled flows, or where hydrogeologic conditions such as
eroded or unstable confining layers require special construction to successfully complete a well or
boring and confine the artesian pressure.” In addition to requiring special construction techniques,
contractors must notify Well Management Section field staff prior to starting work so that arrangement
for inspection can be made.
If a well or boring contractor is unprepared to handle flowing conditions, regaining control of high flows
can be extremely difficult and can result in a variety of serious problems. Uncontrolled flows can cause
serious land erosion and land subsidence problems, create unsafe conditions, damage drilling equipment
and structures, and waste groundwater. Once control of flowing groundwater from the drill hole is lost
and the drill hole starts to erode, it is often very difficult to regain control, contain the flow, and
complete the well or boring.

Local Regulation of Wells – Updated Information
By now, many of you have probably seen the League of Minnesota Cities’ Web posting regarding local
regulation of wells. The Minnesota Department of Health (MDH) has already heard from a number of
contractors asking what this means.
Minnesota statutes clearly prohibit cities from regulating the construction, maintenance, or sealing of
wells, unless the MDH has delegated the authority (Minnesota Statutes, section 103I.111,
subdivision 3.). Well Program staff have historically interpreted that to mean that local governments
could not ban wells, either public or private, without delegation.
Recently, the League of Minnesota Cities asked MDH to review our interpretation of this requirement,
and attorneys for MDH have now determined that while the language of Minnesota Statutes,
section 103I.111 prohibits local regulation of wells without MDH delegation, it is silent about city
ordinances that simply ban wells. Therefore, Minnesota Statutes, Chapter 103I does not prohibit city
well bans. This determination was then communicated to the League of Minnesota Cities.
The League of Minnesota Cities’ posting correctly confirmed that cities do not have the authority to
regulate the construction, maintenance, or sealing of wells. This means that cities may not establish
“well codes” regulating where a well is located on a property, how a well is constructed, or how a well is
sealed. They also may not require a permit or notification for wells without delegation (Minnesota
Statutes, section 103I.205, subdivision 1).
All state requirements for well notifications and permits remain in effect, as well as all the other
provisions of Minnesota Statutes, Chapter 103I; Minnesota Rules, Chapter 4725; and Minnesota Rules,
Chapter 4727.

Lost Municipal Well that Caused Waterborne Disease Outbreak in the
1920s is Found in Hastings, Minnesota
The Dakota County Environmental
Management Delegated Well Program and the
Minnesota Department of Health (MDH) Well
Management Section have worked together
with the city of Hastings Public Works
Department, to locate the original Hastings
municipal Well Number 1, which was taken
out of service and buried in the 1930s, without
ever being properly sealed. An original well
construction record did not exist for the well.
Available documents referencing the well
indicated that it was 415 feet deep and was
constructed prior to 1911. Minnesota State
Board of Health engineering reports indicated
that the well was located in the bottom of a
14-foot square by 18½-foot deep well pit,
within 25 feet of the Mississippi River in
Fire Insurance Map from 1924 showing location of Hastings
downtown Hastings, Minnesota. The reports original municipal Well Number 1 and its pump house near
the Mississippi River in downtown Hastings, Minnesota.
also indicated that the well provided
approximately 90,000 gallons of water per
day to residents in the city; filled two coaches of the Chicago, Milwaukee, and St. Paul Railway
Company; and also furnished water to the railroad depot.
Early sanitation reports indicated the presence of as much as 10 feet of “waste water” in the well pit.
Consequently, the sanitary conditions of the well were rated as “unsatisfactory.” Recommendations were
made to seal the well pit floor with concrete. Improvements were made in the early 1920s and a new
motor driven centrifugal pump was installed in 1922. Coliform bacteria were detected in the water on
repeated occasions after the improvements were made. Repeated disinfection of the system improved the
bacteriological quality of the water.
A Minnesota State Board of Health engineering report from October 1928 indicated that on
September 28, 1928, an outbreak of diarrhea and intestinal disturbances was reported in the city of
Hastings, and that 12 water samples collected from the distribution system were contaminated with
bacteria. Additional water samples were collected directly from the well after disinfection and were
found to be positive for bacteria. The field engineer, O.E. Brownell, reported that the well “was not
properly protected and located.” The MDH, Division of Sanitation recommended that direct injection of
chlorine into the distribution system take place until a new well could be located and constructed, and
that the new well be constructed far enough from the Mississippi River and other sources of
contamination to prevent the contamination of the water supply.
In 2009, staff from the Dakota County Environmental Management Department’s Delegated Well
Program obtained fire insurance maps from as far back as 1911 showing the location of a city
pumphouse and well in Levee Park in downtown Hastings, Minnesota. There was no well sealing record
on file indicating that the well had been properly sealed. Dakota County staff conducted a magnetometer
survey in the park to search for the well and detected a large magnetic anomaly in the park near the
Mississippi River. The anomaly was so large, staff weren’t sure if it was the well or some other buried,
4
metallic debris. In addition, there was a large, memorial ash tree growing in the middle of the area where
the well was suspected to be buried and the city was very wary about excavating near the tree and
potentially harming it. The tree had been planted by the American Legion Post located adjacent to the
park.
In May 2009, the MDH Well Management
Section was asked to resurvey the park with a
magnetometer. The MDH came up with the
same high readings, consistent with a large,
buried, steel-cased well. The city of Hastings
had an excavator on-site that day and did
some preliminary excavation next to the tree
and found two heavy steel rails, buried
horizontally approximately 1-foot below the
surface. The rails were embedded in concrete
and extended underneath, and beyond the
tree trunk.
After several discussions and negotiations
about the fate of the tree and budgeting, the
Otto Excavating Company removing steel reinforcing rails
city agreed to remove the tree to perform
of pumphouse floor covering old well pit.
more extensive excavation in this area to
search for the well. On April 26, 2010, the city of Hastings removed the tree and began removal of the
steel rails that were underneath it. After the rails were removed, it became evident that the old well pit
had been uncovered. The steel rails were supports for the poured concrete floor of the old well house.
Further excavation revealed the 14-foot square well pit. It had apparently been filled in with demolition
debris from the pump house, sand, and pieces of asphalt. It took two full days to remove the debris and
distribution piping in the pit that were on top of the well. Both an excavator and a vacuum truck were
used to clean out the 18-foot deep well pit. The old, motor-driven, centrifugal pump was found in place
on its base next to the well casing at the bottom of the pit, still connected to the 10-inch diameter well.
Centrifugal pump and well at the bottom of the 18-foot deep
well pit.

Now that the well had been located, a plan
had to be devised to properly seal the well.
The well was located within 50 feet of the
Mississippi River and the top of the well
casing was 17 feet below the surface;
approximately river level. It was anticipated
that artesian conditions, where water would
flow freely from the well, would be
encountered once the pump and suction pipe
were removed from the well. The city of
Hastings hired Kimmes-Bauer Well
Drilling, Inc., from Hastings, Minnesota, to
remove the pump from the well, extend the
well casing above the ground surface to stop
any artesian flow, and to temporarily cap
the well.
Employees of Kimmes-Bauer unbolted the pump and
suction pipe on April 28, 2010, and hoisted them out
of the well. Water began to flow freely from the well.
The city of Hastings had set up a centrifugal pump
and suction hose and began pumping water from the
well pit so that an inflatable packer could be installed
into the well. The pump had trouble keeping up with
the rising water level in the pit. Employees of
Kimmes-Bauer were able to insert their packer,
despite the rising water, and stop the flow of water
from the well. A 10-inch diameter extension pipe was
then bolted onto the well casing to extend it above the
top of the well pit. The inflatable packer was then
removed and the water rose in the casing to within
7 feet of the surface before it stopped rising.
Once this work was accomplished, the MDH’s Well
Management Section televised the well, and the
Minnesota Geological Survey gamma-logged the well
to determine how the well was constructed and what
methods would need to be employed to properly seal
the well. These surveys showed that the well was
constructed with 10-inch diameter steel well casing
from the surface to 70 feet.
With the inflatable packer in place to shut off the
artesian flow of water, Aaron Bauer prepares to
bolt on casing extension.
Based on the information generated by the video
inspection and gamma-log, the MDH determined that the 10-inch casing was set inside of a larger bore
hole, or casing, and that perforation of the casing was necessary prior to sealing in order to properly seal
the well. The total depth of the well was 481 feet and the geologic formations penetrated were:
Interval
Geologic Formation
0-20 feet
20-83 feet
83-198 feet
198-232 feet
232-406 feet
406-461 feet
461-481 feet
Glacial deposits
Prairie du Chien limestone
Jordan sandstone
St. Lawrence (confining layer)
Franconia sandstone
Ironton-Galesville sandstone
Eau Claire (confining layer)
The city of Hastings hired Kimmes-Bauer Well Drilling, Inc. to perforate the well casing and seal the
well. Kimmes-Bauer employees used a wheel perforator to perforate the well casing and then
permanently sealed the well with 11½ yards of neat-cement grout on July 8 and 9, 2010.

This case highlights the need for cities and
regulators to examine the history of city water
systems and to determine the status of all old
wells that are no longer in use. Old wells that
are no longer in use and are not repairable must
be permanently sealed by a Minnesota licensed
well contractor or well sealing contractor. A
Well and Boring Sealing Record must be
completed by the contractor and submitted to
MDH for the well to be considered to be
properly sealed. Persons can contact the MDH
Well Management Section at 651-201-4600, to
determine if a Well and Boring Sealing Record
is on file for a particular well.
As a footnote to this story, prior to having the
well sealed, the city of Hastings was informed
that this public water-supply well might qualify
for well sealing grant money through the
MDH’s Source Water Protection Section. The
grant money comes from the Minnesota Clean
Water, Land, and Legacy Amendment Fund.
Certain community and noncommunity watersupply systems are eligible for funding. The
city of Hastings applied for, and was awarded,
$10,000 in grant money to help pay for the well Aaron Bauer and Phil Doffing, with Kimmes-Bauer Well
Drilling, Inc., finish sealing the well with neat-cement
sealing costs. For more information on this

September Flooding in Southern Minnesota
Heavy rains of up to 10 inches over a two day period caused record flooding in southern Minnesota in
September 2010. Twenty-nine southern Minnesota counties received Federal Major Disaster
declarations. Some of the towns affected by the flooding included Owatonna, Pine Island, Truman,
Oronoco, Cannon Falls, Zumbro Falls, Northfield, and New Richland. Many homes had to be evacuated,
Highway 35 in Owatonna was closed for a period of time, and a bridge in Oronoco washed out.
Minnesota Department of Health (MDH), Well Management Section staff participated in the emergency
response by staffing the Department Operations Center (DOC), coordinating MDH response activities,
and arranging well testing services for owners of flooded private wells with the MDH Public Health
Laboratory. Well Management Section staff in southern Minnesota distributed water sample kits to local
governments, contacted well owners whose flooded wells were contaminated with bacteria, assisted well
owners with well disinfection questions, and provided technical assistance to well owners whose wells
were in need of repair or replacement. Approximately 500 well test kits were distributed for the flood
event. To date, approximately 80 wells have been tested, with half testing positive for coliform bacteria.
Response to this flooding event will likely last into the spring of 2011.

News Stories on Arsenic in Western Metro Drinking Water
In the summer of 2010, several twin cities television stations broadcast news stories reporting that a
large number of private water-supply wells in the cities of Deephaven and Shorewood in Hennepin
County, had elevated levels of arsenic. Reports stated that many wells in these communities exceeded
10 micrograms per liter (µg/L).
Since August 2008, Minnesota Rules, Chapter 4725 (the well code) has required that all new watersupply wells constructed in Minnesota, be tested for arsenic. The results collected from new wells
constructed since 2008 indicate that the number of new wells with arsenic exceeding 10 µg/L in
Deephaven and Shorewood, is similar to the statewide average of 9 percent.
Plumbing and Well Work
The Minnesota Department of Labor and Industry (DLI) licenses plumbers and regulates plumbing work
in Minnesota. The Plumbing Board establishes and amends the Plumbing Code.
Amendments to the plumbing licensing law in 2007 established a state-wide requirement for a plumbing
license and bond to contract for plumbing work anywhere in the state. “Plumbing” is basically defined
as potable water piping or sewer piping within a property. The law contained no exemptions for
plumbing work that historically has been done by well contractors. The 2007 law also created a
restricted plumbing license, which allows a restricted plumber to do plumbing work except in cities over
5,000 population. A number of well contractors have obtained this license. The restricted license
application period has expired, and unless the law is changed, no new restricted licenses will be issued.
The DLI determined that since the well rules regulated “pumps and pumping equipment,” a
Minnesota Department of Health licensed and bonded well contractor could install a water line from
a well to a pressure tank without a plumbing license; however, this exemption did not extend to the
installation of frost proof hydrants and water lines to stock waterers, barns, and other out-buildings.
The Minnesota Water Well Association (MWWA) met with the DLI, the MDH, and the Plumbing
Board to discuss an amendment to the law allowing this work to be done by a well contractor without
a plumbing license. The plumbing law was amended in 2010; however, the amendment is not in
effect until January 1, 2012. The amendment sunsets after one year, and the amendment only allows
the installation of “ . . . (1) water service pipe from a well to a pressure tank or a frost-free water
hydrant with an antisiphon device which is located entirely outside of a structure requiring potable
water, or (2) a temporary shut-off valve on a well water service pipe.” The MWWA is continuing to
meet with interested parties concerning further amendment of the law.
