St. Paul Mayor Randy Kelly, Minnesota Department of Health (MDH) Commissioner Dianne Mandernach, Governor Tim Pawlenty,
Jane Freeman, and Mike Freeman scoop the first shovels of dirt for construction of the Orville Freeman Office Building, which will
house the state’s drinking water program beginning in 2005 and be connected to a new laboratory. The laboratory building will
have 178,000 square feet distributed between three floors and a mechanical penthouse. It will be designed to better accommodate
water systems dropping off samples. The map below on the left shows the laboratory to the south of the new MDH building (which
will also house the Department of Agriculture). The map on the right—indicating the same area in 1903—shows what was on the
lab site 100 years ago: a baseball park that was used by the St. Paul Saints minor league team from 1903 to 1909.

Innovative Treatment Methods
for Arsenic Removal
Trivia Time
1. What is the only Alfred Hitchcock movie with nudity?
a. Family Plot b. Frenzy c. Topaz d. Bambi
Systems with arsenic greater than the upcoming maximum
contaminant level of 10 parts per billion (ppb) have several
options to choose from to reduce their levels. Some systems
have been able to locate new wells that are low in arsenic
while others have limited the use of the high-arsenic well or
constructed an interconnection to purchase water from
another system. Activated alumina, adsorptive media, anion
exchange, coagulation/filtration, membrane processes, lime
softening, and iron/manganese filtration are all effective
methods for removing arsenic from drinking water.
Several water systems in Minnesota are looking at
innovative methods for arsenic removal. The city of Hanley
Falls has relatively low iron in its water (0.094 parts per
million) and arsenic concentrations between 21 and 29 ppb.
Due to the quality of their raw water, their filter media does
not require chemical addition prior to filtration, and the media
is replaced once it has reached adsorptive capacity. Arsenic
attaches to the iron-based granular adsorptive media,
making it an effective and relatively inexpensive treatment
option.
The city of Climax has somewhat higher iron (0.61
parts per million) and arsenic concentrations of 29 to 41 ppb.
Due to the elevated iron concentrations, iron removal
becomes necessary for effective arsenic removal. As part
of the U. S. Environmental Protection Agency (EPA) arsenic treatment demonstration project, the city is installing a
coagulation/filtration treatment plant later this year. The
coagulation/filtration process includes pre-oxidation with
chlorine, contact time, and pressure filtration with a ceramic
media. The city has the additional benefit of iron removal, as
arsenic adsorbs onto the oxidized iron and is removed during
the filtration process.

Consumer Confidence Reports
More than 95 percent of the Consumer Confidence Reports for 2002 were received by MDH by the July 1 deadline. The
compliance staff continues to work on receiving the remainder. Since the 1998 report, the first that community water supplies
were required to produce and distribute to their customers, Minnesota has had better than a 99-percent compliance rate each
year. Many of the reports received have been outstanding, according to Pat McKasy, the senior compliance officer for the
MDH drinking water program. They were entered into a contest to determine the best Consumer Confidence Report. The
winners from each of the six districts in the Minnesota Section of American Water Works Association (AWWA) are:
Central—City of Ortonville
Northwest—City of Fergus Falls
Metro—City of Bloomington
Southeast—City of Waseca
Northeast—Hibbing Public Utilities
Southwest—City of Mankato
The overall award winner will be announced during the Minnesota Section AWWA Annual Conference in October. Past
overall winners are Edina for 2001, Woodbury for 2000, Richfield for 1999, and Worthington for 1998.
COMPLIANCE CORNER
New Monitoring Requirements
By Patricia McKasy, Senior Compliance Officer
Disinfection of drinking water is one of the major public health
advances of the 20th century. However, the disinfectants
themselves can react with naturally occurring materials in the
water to form unintended byproducts that may pose a health
risk. A major challenge for water suppliers is balancing the
risks from microbial pathogens and from disinfection byproducts.
The Stage 1 Disinfectants and Disinfection Byproducts Rule
(DBPR) and the Interim Enhanced Surface Water Treatment
Rule together address these risks.
Chlorine and chloramines (formed when ammonia is added
during chlorination) are widely used and highly effective
disinfectants. Under the DBPR, the EPA has set the
maximum residual disinfectant level (MRDL) at 4.0 milligrams
per liter (mg/l) for both chlorine (measured as free chlorine)
and chloramines (measured as combined total chlorine).
Beginning January 1, 2004, a specific component of
the DBPR requires Community Water Supplies
and Nontransient Noncommunity Water Supplies that use
disinfectant to measure and record the disinfectant
residual level at the same points and the same time as
the monthly or quarterly total coliform samples are
collected, and report the levels to the primacy agency
(MDH).
A system is in compliance with the MRDL when the running
annual average of monthly averages of all samples, or the
annual average of four quarterly samples, is less than or equal
to 4.0 mg/l. However, despite the 4.0 mg/l MRDL, operators
may increase the residual chlorine levels in the distribution
system to a level greater than 4.0 mg/l for a time if necessary
to protect the public health in addressing specific
microbiological contamination problems (e.g., including
distribution line breaks, storm run-off events, source water
contamination, or cross-connections).
The EPA believes that the MRDL of 4.0 mg/l for chlorine
and chloramines is appropriate to control potential health
effects from chlorine, while high enough to allow for control of
pathogens under a variety of conditions. The EPA also
believes that compliance based on a running annual average is
sufficient to allow systems to increase residual chlorine levels
in the distribution system to a level and for a time necessary to
protect the public health as well as to address specific microbiological contamination problems and still maintain compliance.
3
Failure to monitor for disinfectant residuals and/or
failure to report to MDH the results of the required monthly
or quarterly total coliform samples is a monitoring
violation. When compliance is based on a running annual
average of monthly averages, or the average of four
quarterly samples, the system’s failure to monitor makes it
impossible to determine compliance with the MRDL;
thus, this failure to monitor will be treated as a violation and
reported to the EPA.
Sometime near the end of 2003, MDH will send letters
to all the affected systems, reminding them of this
additional monitoring and reporting requirement.
The laboratory reporting forms used by both the larger
systems that submit monthly total coliform samples and the
smaller systems that submit total coliform samples
quarterly are in the process of being revised to allow space
for reporting the disinfectant residual levels. Revised forms
will be provided to the systems and/or to the certified
laboratories used by the water supplies to analyze their
samples. Systems that submit monthly samples should
speak to their laboratory to determine the best way for
reporting the disinfectant residual levels so that they will
be reported to the state along with the results of the total
coliform samples.
If you have any questions regarding this new
requirement, please contact me at 651/215-0759.
Anti-Bottled Water Web Site
A web site devoted to debunking bottled water and
providing “information on consumer actions against bottled
water companies that we believe are duping customers
into paying for what they could get straight from the tap”
is at http://www.bottledwaterfraud.com/index.html.
“During the dramatic rise in bottled water consumption
in the last ten years, some bottling companies have
stretched their original water sources so thin they began to
use common groundwater and wells near hazardous
contamination, all the while touting their bottled water as
naturally pure and pristine,” the web site notes, adding
information on a national class-action lawsuit against the
makers of Poland Spring water, claiming that the bottles
are improperly labeled as spring water.

Hands-on Basic Training for Water Operators at Vermilion Community College
In addition to providing courses for aspiring water
operators, Vermilion Community College in Ely has a new
training center and is offering hands-on basic water
operations training to public water systems serving fewer
than 3,300 people. The two-day hands-on training course,
Class E or D certification application and license fees, one
college credit, meals, and two nights lodging in Ely will be
free to qualifying systems. (Other systems or individuals may
attend this training for a separate fee.)
This program is supported and funded to Vermilion
Community College until 2009 through a Minnesota
Department of Health Operator Certification Grant. This
effort to provide water industry personnel with quality
on-site and hands-on training will ensure that operators have
the knowledge and skills to supply safe drinking water to all
individuals served by public water systems.
The first two training courses were held in August. Dates
and topics of upcoming training are:
October 13-14, 2003—Groundwater
March 9-10, 2004—Surface Water
