Changes in MDH Drinking Water Structure
Feeling the Earth Move
The Minnesota Department of Health (MDH) Division of Environmental
Health has been reorganized. As part of this reorganization a Section of
Drinking Water Protection (DWP) has been formed to deal with activities
related to the Safe Drinking Water Act (SDWA). Managed by Gary Englund,
DWP consists of four units: Community Water Supply, Noncommunity Water
Supply, Source Water Protection, and Technical and Administrative.
The Community Water Supply Unit, supervised by Dick Clark, is
responsible for SDWA compliance and enforcement activities for community
water systems. This unit includes the field staff that inspects, samples, and Earth, lots of it, has been moving at the site of a
new reservoir for Minneapolis Water Works.

samples, and provides technical assistance to noncommunity water systems. In addition, this unit coordinates noncommunity
compliance activities with local health agencies and the Environmental Field Services Section of the division.
The Source Water Protection Unit, supervised by Bruce Olsen, is responsible for source water and wellhead protection
activities required by the SDWA. This unit provides technical assistance and compliance activities for both community and
noncommunity water systems to ensure that source water is adequately protected; it also manages the Geographic
Information System used to gather and map much of the information needed to perform source water protection activities.
The Technical and Administrative Unit, supervised by Doug Mandy, handles most of the technical and administrative
support functions for the other units. This support includes the drinking water revolving loan fund, engineering plan review,
operator education and certification, data management, enforcement, and grants and contracts.
The support staff, supervised by Marilyn Krause, provides general support services for the section.
1998 Legislative Initiatives
To satisfy requirements of the 1996 amendments to the Safe Drinking Water
Act (SDWA), the MDH drinking water program will be pursuing a pair of
legislative initiatives this session.
The first proposes the creation of administrative penalty amounts specific to
public water supply systems serving more than 10,000 people and would include
authority for penalties of $1,000 per day per violation, up to a maximum of $10,000
per violation. Without this change, Minnesota would lose its delegated
authority—and with it, its federal grants that totaled approximately $45 million in
1997—from the U. S. Environmental Protection Agency (EPA).
The other initiative would require new community and nontransient noncommunity systems to submit documentation of their technical, managerial, and financial
capacity to establish that the system can maintain compliance with federal SDWA
requirements. Minnesota must adopt this authority to prevent a 20 percent
reduction of its drinking water revolving loan grant (which was approximately $42
million in 1997). It is estimated that few systems will be affected by this rule.

Minneapolis Increases Capacity
New Reservoir to Expand Storage
A half-million Twin Cities residents
rely on Minneapolis Water Works for
their drinking water. In addition to
Minneapolis, the utility supplies the
suburbs of Hilltop, Golden Valley,
Crystal, New Hope, Columbia Heights,
and portions of Edina and Bloomington,
including the airport and Mall of America.
All the water in the Minneapolis system
comes from the Mississippi River. If the
river were to become contaminated,
Minneapolis would have to depend on
the treated water it stores in reservoirs.
Its current storage capacity allows for a
one day of reserves under normal flow
rates (slightly longer with use restrictions
that would be imposed during an
emergency).
Last year, the city began a multimillion-dollar project to increase its
storage capacity by 30 percent through
the construction of a new reservoir at
its Hilltop site in New Brighton,
approximately five blocks east of their
Columbia Heights filtration plant. The
40-million gallon reservoir (measuring
540 x 432 feet) will be 125 feet north of
an existing 40-million gallon reservoir
that was built in the 1950s. The site is at
the highest point in the Twin Cities,
meaning that, after water is pumped to
the reservoirs, it can feed into the
distribution by gravity, eliminating the
need for a pumping station and the
resulting construction, maintenance, and
electrical costs.
The design concept of the new
reservoir consists of cast-in-place
concrete, underground twin cells
constructed using a slab-on-grade mat
foundation, supporting concrete interior
columns, and 24-foot-high poured
concrete walls. The two-way flat
concrete roof slab, which will be topped
by a membrane and covered by three
feet of soil, will be supported by
concrete columns and concrete walls.
Trees, shrubs, and prairie grasses will
be used to make the site as attractive as
possible, according to Galina Izraelev, the
project engineer for the city.
Clearing of the site began last May
with earthwork commencing in October.
Veit & Company of Rogers, Minnesota
performed the $3.9-million contract for
earth moving. The uneven topography
on the site—with surface elevations

reservoir for Minneapolis Water Works.
ranging from 345 feet at the southern
portion to 325 feet at the northern end—
has resulted in a great deal of cutting
and filling with some of the fills reaching
depths of 25 feet. Veit & Company
removed inadequate soils and placed
and compacted new material to
support the weight of the reservoir.
Much of the cutting and filling was
related to the consolidation characteristics of the soils beneath the heavily
loaded structure.
Using soil excavated from the
southern part of the site greatly
reduced truck traffic, thereby reducing
the effects of the construction
activity to neighbors, a concern to
residents in both New Brighton and
Columbia Heights as well as the
Columbia Heights Public Schools.
Izraelev and Water Works’ management have attended numerous public
meetings and worked with the
cities and school district to coordinate a
hauling schedule to minimize the impact
of the construction.
The contract for the concrete work,
estimated to be around $15 million, will
be let in the winter of 1998-99 with
construction of the structure beginning
in the spring of 1999.
As the reservoir is being built, a
watermain construction crew from
Minneapolis Water Works will install
interconnecting piping and valves
between the new and existing reservoirs.
Construction on the reservoir is
expected to be completed in 2000 with
landscaping to be done in the spring of
2001.

Confined Spaces: Treat with Respect
On what he described as a “routine
day” last September, MDH engineer
Mark Sweers visited a water system in
his South Central Minnesota district.
Instead of a pump house, this system had
a meter pit on one of its wells. “In
comparison to a lot that I’ve seen, this
one is a well constructed pit, very clean,
with good access to the pit,” says
Sweers. “It’s been in service for ten
years with no problems.”
Sweers went into the pit, followed by
the system’s utility superintendent, and
immediately felt nauseous. He had been
fighting the flu and at first thought he
was experiencing symptoms from that.
But then his chest got heavy and he had
difficulty breathing. The utility
superintendent was also having trouble
breathing. “Is there bad air in here?”
Sweers asked.
“Let’s get out of here,” was the
reply. They quickly climbed back up the
ladder and got outside. Both felt woozy
and shaken by the experience. Staff
from the water utility checked the pit and
found it was low in oxygen.
The ending to this story could have
been worse—far worse. Sweers and
the utility superintendent were fortunate
that the pit had a fixed ladder and large
enough access to allow for a fast exit.
Many confined spaces are much harder
to get out of. And, in cases of oxygen
deficiencies, often a person does not
realize something is wrong until it is too
late.
But the hazards of confined space
extend beyond concerns over access and
atmosphere. Bill Anderl, another MDH
district engineer and a safety expert, says
one of the issues is recognizing what a
confined space is. “Many things that
water supply personnel deal with, such
as iron filters with multi-celled tanks, are
often ignored in terms of concern
because they are not thought of as
confined spaces,” he explains.
Confined spaces share three elements:
1) they often limit or restrict ability to
enter or exit quickly; 2) they are not
designed to be occupied; and 3) they
often contain multiple hazards.
The size, shape, and location of the
access port for a confined space can
increase the time it takes to get out of
an area should a problem occur. Some
openings are small, others are shaped in
Bill Anderl helps MDH district engineers calibrate their gas detectors.
such a way that impedes access, and some are at the top of tall vessels, such as
water towers, and may have their openings partially blocked by parts of
machinery.
A lot of spaces are difficult to be inside of (let alone perform work in) simply
because they weren’t designed to be occupied. It can be difficult to work in close
quarters, and overexertion is a hazard. Work procedures in a confined space may
differ from those of the same task in an open area. The shape of the space may
increase the risk of becoming wedged or trapped. In others, slips and falls become
more likely. Just the act of being confined can affect a person’s senses. It can be
difficult to see or hear clearly; feelings of disorientation can add to the probability
of an accident.
Part of a process
Confined spaces can be dangerous for no other reason than they are confined
spaces; however, the hazards associated with confined spaces can increase
because of the system or process the space is a part of. For example, some
spaces store or pressurize chemicals; others contain moving machinery.
One of the greatest concerns with confined spaces deals with the atmosphere in
them (the danger that Sweers and the utility superintendent encountered). Gases
and vapors in a space may be toxic. They can be from leaks, but they can also be
created by the work being done within the space. Solvents and adhesives being
used in the work space can be the source of such vapors. And because of the
limited ventilation of a confined space, these gases and vapors may concentrate.
But even greater than the presence of toxic fumes is the risk of asphyxiation
caused by oxygen deficiency. Covered pits sometimes have little or no oxygen.
Sometimes the process of the confined space, even the chemical action of rusting
equipment, robs it of oxygen. Other things, such as the bacterial action of soil or
fermentation, also consume oxygen. Even the walls of a space (or what’s inside
the walls) can suck up oxygen. A non-toxic damp charcoal filter can absorb
oxygen in a space. Gases such as carbon dioxide, argon, and nitrogen can displace
oxygen. Don’t get complacent regarding the atmosphere within a
confined space, even if you know chemicals or other toxic materials are not
present. An oxygen-deficient space is one of the most dangerous places to be.
Machinery and equipment within a confined space pose hazards. They can
serve as an ignitor, providing a flame or spark, and increase the risk of an
explosion. Powered devices that are not locked out can cause shocks or other
injuries from contact with the equipment.
Anderl points out that not only are medical emergencies, such as slips, seizures,
injuries, more likely in confined spaces because of the conditions, such an
emergency can be more dangerous. “If the emergency leaves you incapacitated,
you may not be discovered by someone for a much longer period of time because
of where you are,” he says.
Controlling Confined Space Hazards—Go to page 7
6
MDH district engineers have now been issued additional
testing equipment along with training on how to use gas
detectors and other information on the hazards of confined
space and how to control them.
For Mark Sweers, the close call he had in the meter pit
has made him even more careful in dealing with these
situations. “Be respectful of confined spaces,” he says.
“Check them first because you never know.”
Confined Space—Continued from page 6
Controlling Hazards
But hazards associated with confined spaces can be
controlled with proper precautions and work practices.
Control procedures involve isolating the space from processes
and systems that may create hazards within the space.
Locking out energy sources, bleeding liquid and gas lines into
the space, locking circuit breakers, and securing moving parts
are all control procedures.
But these may not be enough. Protective equipment such
as gloves, helmets, safety glasses, ear plugs may be
necessary in addition to air-supplying respirators and retrieval
lines.
Finally, remember the importance of testing and
monitoring. Never trust your life to a space that hasn’t
been tested. In addition to testing the atmosphere before
entering, monitor the atmosphere, in case it changes, during
occupancy.
