New Seminar on Drinking Water
Systems Offered for Local Officials
More Fun Than a Science Experiment
A one-day seminar on drinking water systems, geared for
local officials in communities with populations of 10,000 or
fewer, is being held on Tuesday, June 8, at the Holiday Inn in
St. Cloud. Managing a Drinking Water System: A Short
Course for Local Officials—conducted by the National
Environmental Training Center for Small Communities, in
conjunction with the Minnesota Section of the American Water
Works Association (AWWA)—is designed to help local
officials implement management practices that will improve
their ability to provide safe drinking water to their
communities in accordance with the reauthorized federal Safe
Drinking Water Act. The modular training package addresses
the major topics that local officials need to know to develop
and enhance the technical, managerial, and financial
capacity of their drinking water systems. The modules
include Local Official’s Responsibilities for Providing Safe
Drinking Water, Regulatory History and Current
Requirements, Basics of a Drinking Water System, Best
Management Practices, and Financing Options for System
Projects or Upgrades.
The target audience for this seminar includes elected
officials, such as mayors and city council members, as well
as city administrators, including town managers, planners,
auditors, and clerks. Registration for the seminar is $45 (which
includes lunch) and is limited to the first 20 participants to
register.

Madison Reverse-Osmosis Plant
Regulatory Update
Total Coliform Testing
Madison Leads the Way
First Reverse-Osmosis System for Municipal Water Supply in Minnesota
A west-central Minnesota town of
1,900 that is the self-proclaimed
“Lutefisk Capital of the World,” the city
of Madison has another distinction. It is
the site of the first reverse-osmosis
treatment used in a municipal water plant
in the state.
History
Madison’s first water system, built in
1913, pumped water directly from a well
into the distribution system. In response
to complaints about hardness, in 1939 the
city constructed a lime softening plant
that served them for more than half a
century.
The lime-soda ash treatment process
did an adequate job of softening, but it
wasn’t removing the high levels of
naturally occurring sodium sulfates. Iron
and manganese were also a problem.
These issues, combined with the
realization that the plant was nearing the
end of its useful life and concerns about
future lime-sludge disposal efforts, made
it apparent that a new facility was
needed with a number of issues to be
considered in determining what type of
plant to construct. A primary
consideration was the desire to continue
to reduce the hardness of the water
supply, an amenity the townspeople were
accustomed to and would undoubtedly
demand again.
Madison is the first municipal water supply in Minnesota to use reverse-osmosis
Options
Lime softening and two membrane
processes—reverse-osmosis, and
electrodialysis reversal—were the
options Madison looked at. Lime softening was rejected because it would not
meet all of the needs, while the high capital cost of electrodialysis reversal caused
the city to shy away from it. That left
reverse-osmosis as the frontrunner.
In the summer of 1994, a reverseosmosis treatment process was pilot
tested using one of the city’s wells. The
membrane was able to achieve an
overall recovery rate of 75 percent
during the testing period. The following
year, Bolton & Menk, Inc. of Mankato,
Minnesota, completed a pilot plant study
using a bench-scale model of a reverseosmosis unit. Brian DeWolf of Bolton
& Menk said the study indicated
success in reducing iron, manganese,
sulfate, and total dissolved solids as well
as hardness.
The decision was made to construct
a reverse-osmosis plant—with a process
consisting of aeration, detention, and
filtration—along with two new wells, a
300,000-gallon tower, and water mains
to connect the new plant to the existing
distribution system. The membrane
treatment technology was selected in
part because of its ability to eliminate
the high chemical and labor costs and
the lime-sludge problems associated with
the existing treatment facility.
Construction began in March of 1997
and was completed by late summer in
1998. DeWolf says the reverseosmosis process is a 7-4 system,
meaning that it has seven first-pass
membranes and four second-pass
membranes. “Water that doesn’t make
it through the membranes on the first
pass is subject to the second-pass
membranes, which increases the
recovery rate,” he explains. “The
recovery is about 75 percent, and the
city blends about 35 percent
filtered-only water with 65 percent
reverse-osmosis water, so the overall
plant efficiency is just over 80 percent.”

Madison is now known for more than just lutefisk

Madison Reverse-Osmosis Plant—Continued from page 2
The fact that only four of every five gallons entering the plant ends
up going to the consumers is what DeWolf calls, “one of the real
drawbacks of a reverse-osmosis system—a high level of rejection.”
However, he notes that since the plant went on-line, the water that
makes it through the membranes is about 97 percent free of
hardness, sulfate, sodium, and arsenic.
Treatment Process
Approximately 380 gallons per minute (gpm) are pumped from the
wells. The first stage of treatment is aeration to oxidize the iron and
manganese, an economical process that reduces chemical
requirements and forms a more filterable precipitate. Occasionally
chlorine is added to assist in the oxidation. Potassium permanganate
is added to aid in the removal of manganese before the water goes
into the detention basin, which is baffled to provide 30 minutes of
oxidation. The basin has sludge drawoff piping to aid in cleaning any
settled solids from the bottom. The settled solids are discharged into
the sanitary sewer or the backwash holding tank. Greensand
filtration, which further reduces the manganese level, is the next step
in the treatment chain.
DeWolf says pretreatment is a key part of a reverse-osmosis plant.
“Removal of iron and manganese is critical to the reverse-osmosis
process. Any amount of insoluble particles of iron and manganese
can foul the membranes.”
After the greensand filtration, the water enters the first clearwell
and is then split with 80 gpm going to the second clearwell, to be used
for blending with the finished reverse-osmosis water. The other 300
gpm goes into the reverse-osmosis unit, receiving hydrochloric acid
on the way to lower the pH to 6.8. Sodium metabisulfate is
sometimes added to remove any chlorine residual. An anti-scalant is
also added.
Approximately 210 of the 300 gallons make it through the membranes—either on the first or second pass—with approximately 90
gallons rejected to the storm sewer. The pH of the water that makes
it through the membranes is raised to 7.2 with the addition of a
caustic. It is then mixed with the filtered-only water in the second
clearwell and pumped to the distribution system at 290 gpm as
chlorine, fluoride, and a polyphosphate are added.
The plant cost of $1.5 million included both the gravity filtration for
the pretreatment and the reverse-osmosis membranes as well as the
electrical and control systems and the building itself. DeWolf
estimates that, for this particular system, the addition of reverse-osmosis added approximately $300,000. The cost of the total project—
including the new tower, wells, and mains—was approximately $2.9
million and was funded by a Rural Utilities Service loan from the
U. S. Department of Agriculture of $2.3 and a grant from the Minnesota Department of Trade and Economic Development of $600,000.
Certification Q & A
In order to comply with the Minnesota statutes
that regulate our program, MDH is required to
enforce specific certification deadlines. Here are
some commonly asked questions individuals
concerning water operator certification deadlines.
HOW DO I APPLY FOR CERTIFICATION?
Fully complete the examination application form
and submit it with the correct fee to the Minnesota
Department of Health. The deadline for accepting
applications is 15 days before the examination date.
HOW OFTEN MUST I RENEW MY
CERTIFICATE?
Your certificate expires three years from the date
of issue. You will be mailed a renewal notice fourto-six weeks in advance of your certification
expiration date. A certificate may be renewed only
if the operator can provide proof that the education
requirements have been met. A certificate in any
given classification must be renewed within 30 days
of its expiration date.
WHAT ARE THE RENEWAL REQUIREMENTS?
In order to maintain certification, continuing
education requirements must be met by all certified
operators of municipal and nonmunicipal systems.
Operators are required to demonstrate professional
growth by attending approved water and
wastewater industry related training to acquire
contact hours within a three-year period in order to
renew their certificates. At least 50 percent of
renewal hours for water certificates must be direct
water operations training. The other training hours
may be from water-related training courses.
WHAT IF I FAIL TO RENEW?
A person who has failed to renew may apply for
reinstatement for up to three years from the
expiration date of their certificate. A certificate may
be reinstated only if the operator can provide proof
that the educational requirements have been met
during the entire time since the certificate was last
issued or renewed. If evidence cannot be provided,
the operator must retake the exam to obtain
certification.
Renewal Reminder for Nonmunicipal Systems
In response to the 1996 revision of Minnesota Rules Chapter 9400, all community nonmunicipal public water supply
systems were asked in 1997 to designate the person chosen to be the system’s certified operator. A conditional water
operator certificate, effective for three years, was issued to each of these operators to be used only at the water system that
had designated him or her as the certified operator. Most nonmunicipal operator certificates will expire April 1, 2000. All
certified operators are required to participate in continuing training to renew their certificates. Most nonmunicipal systems are
Class D, and the operator of a Class D system needs to complete eight credit hours of water operations training every three
years. Courses are offered throughout Minnesota, and most are low in cost or even free. In addition to being listed in the
calendar section on the back page of the Waterline, a list of these courses is available from Minnesota Rural Water
Association (1/800/367-6792) or Cindy Cook (651/215-0751).

By John Schnickel
Between March 15 and May 28, 1999 the Minnesota
Department of Health will be accepting proposals for placing
projects on the Drinking Water Revolving Fund (DWRF)
Project Priority List. Proposals are to be for projects
requiring funding anytime after October 1999. Please be an
exception to the trend and submit your proposal well before
the deadline. Unfortunately, people have found out that making
the deadline was a meaningless victory if critical clarification
was lacking and time had run out to provide it.
City clerks, eligible business owners, and eligible nonprofit
agencies will soon be notified that proposals will be accepted.
There will be one change in this year’s submission
procedures. Only one rather than two submissions will be
required for requesting placement on the project priority list
and the upcoming intended use plan. Call Jeanette Boothe at
651/215-0755 if you would like to receive the proposal
submission requirements.
If you are responsible for one of the approximately 100
projects that can be funded this year, please remember
April 9, 1999 is the deadline for submitting plans and
specifications and the loan application papers. Your project
will be by-passed for funding if the deadline is missed.

Total Coliform Testing
Membrane Filtration vs. Colilert
By Susan Plank
MDH Public Health Laboratories
The most commonly used methods for determining Total
Coliform are Colilert® and Membrane Filtration (MF).
Numerous questions arise when the two methods are used
for the same sample and yield differing results. This usually
occurs when two laboratories are comparing results obtained
using the two different methods. This article will discuss the
basic method protocols and limitations and the Minnesota
Department of Health’s position regarding the reporting of
results. Future installments will encompass reporting
procedures for each of the methods and their possible
outcomes.
The MF technique is the older, more established of the
two methods. In this method a sample is filtered, and
the filter paper is placed on a growth medium and
then incubated. The number of suspected coliform colonies
formed after 22 to 24 hours are counted. If colonies are
present after incubation, the laboratory must perform a
confirmation test to determine that the colonies are in fact
coliforms.
In Colilert® testing, the reagent is added to the sample and
incubated. If the solution has a yellow color that equals or
exceeds the intensity of the comparator, it indicates a
positive result. No change in color indicates a negative
result. This method can yield Presence/Absence results within
24 hours and is less cumbersome to perform than the MF.
Perhaps this is the reason for its increase in popularity.
However, as usage increases, so does the MDH’s concern
that facilities are aware of the limitations of these tests in
evaluating samples for regulatory purposes.
The results for these tests are not always comparable,
which may be due to:
• interferences in the sample that may suppress or
mask bacterial growth;
• greater sensitivity of the Colilert® media;
• added stress to organisms related to filtering; or
• the fact that different media may obtain better growth
for some bacteria.
Although both methods are approved by the U. S.
Environmental Protection Agency for reporting under the Safe
Drinking Water Program, the MDH policy on issues
regarding conflicting bacteriological results is to err on the
side of caution in the interest of protecting human health.
Therefore, MDH requires increased monitoring and
treatment until results for both tests are negative.
