Minneapolis Institute of Art Decorates Water Towers

New Hope Water Tower

The Minneapolis Institute of Art extended its 100th birthday year celebration by bringing art experiences outside museum walls and into the communities. The effort included three water towers in the Twin Cities. New Hope had its tower at U. S. Hwy 169 and Medicine Lake Road adorned with Katsushika Hokusai’s Under the Wave off Kanagawa (above), the Minnetonka tower at Minn. Hwy. 7 and Williston Road had Frank Stella’s Tahkt-I-Sulayman Variation II (below), and the tower in the heart of Chisago City (way below) was decorated with Vincent van Gogh’s Olive Trees. The art was on the towers from the spring to fall of 2015.

Important News about the 2016 Metro School - Registrants to be Capped at 240

The Metro District of Minnesota American Water Works Association and Minnesota Department of Health have been alternating the locations of the Metro District School between the Ramada Mall of America in Bloomington and the Ramada Plaza in northeast Minneapolis. However, the Ramada Plaza is limited in size; as a result, the 2016 school will be limited to the first 240 people to register. Please register early.The Metro District will no longer hold its annual training at the Ramada Plaza after 2016.

Water Success Stories

National Park Service Takes the High Road as Others Try to Stay Low

The National Park Service is taking a strong stand on discouraging the sale of bottle water at its parks despite pressure on Congress from the International Bottled Water Association (IBWA) to cut off federal money the Park Service is using to install bottle filling stations as an alternative to bottled water.

Four years ago Park Service director Jonathan Jarvis told parks they could eliminate the sale of disposable plastic water bottles if they replaced them with refilling stations and sales of reusable bottles. The impetus for this directive was the amount of garbage and recycling costs the parks were facing. In the spring of 2015, the IBWA began lobbying to halt the Park Service’s sustainability efforts.

Lisa Rein, in the Washington Post, quoted IBWA president and chief executive office Joe Doss: “My thought would be, you certainly don’t want to be doing things that Congress has indicated they don’t want you doing. It would seem prudent, if one were a Park Service official, to see that if there’s a clear sense of Congress, you’d have to take that into consideration and you don’t do what goes against that.”  

Rein also reported that the Park Service will call on its network of friends groups and concessionaires to provide the funding for the filling stations, if necessary.

Closer to Home, Minneapolis Promotes Tap Water to People with Fears of It

Blong Yang of the Minneapolis City Council is concerned about the amount of money Hmong families in his city are spending on water because they are leery of what comes out of their tap.

“It’s this transference of their knowledge from, let’s say, Thailand or Laos or some other country, maybe a Third World country,” Yang told Curtis Gilbert for a story in the August 17, 2015 Minneapolis Star Tribune. “Back in the home country, we didn’t trust it. We drank from the bottle. It’s just habit now.”

Promoting trust in Minneapolis water is one way Yang sees to reduce the income disparities between Hmong families and others in the city. He recently arranged a tour of the Minneapolis Water Works water treatment facility to show visitors the sophisticated treatment the water receives after it comes out of the Mississippi River. Plant superintendent Annika Bankston and water quality manager George Kraynick demonstrated to the visitors how water from an impure source is transformed into water that is safe to drink. Kraynick said, “We want people to see what we do, and have you know where your water comes from, and have confidence in that water coming out of your tap. That’s the safest thing in your house. Safer than the food, safer than anything else. That tap water, every drop has been tested.”

Yang said he thought the tour was successful in demonstrating to citizens, especially those from other parts of the world, that tap water is as safe as bottled water and definitely cheaper. He added, “If I can crusade in some ways to get immigrant groups, especially Hmong folks but other folks as well, to not buy their water from the store and to use their tap water, we will save people countless amounts of money, and that’s a good thing.”

MDH Lab Reprocessing Water Sample Data

In September the Minnesota Department of Health (MDH) Public Health Laboratory discovered that imperfect quality assurance procedures were used when processing some water testing data over the past couple of years. This might have affected the interpretation of a small portion of the data the lab generated on behalf of MDH and the Minnesota Pollution Control Agency for environmental health work.

While MDH determined that the possible lapse did not lead to an immediate increased risk to public health, it raises questions about the reliability of some water testing data. MDH is responding by ensuring the calibrations are correct and reprocessing potentially affected samples. The initial focus is on the 2,200 sample analyses in question, which were conducted between May 2013 and May 2015. Special priority is being given to reprocessing samples from public water systems.

MDH has arranged for an external contractor to review the reprocessed data to ensure accuracy. The results considered most sensitive for public health are being reanalyzed first, and the top-priority group includes five municipal water systems, Edina, St. Louis Park, Spring Park, Kasota, and Brooklyn Center. The timeline for the completion of the work will be posted on the MDH website when all steps for the reprocessing work are in place.

Bacteriological Laboratory Changes for Very Small Communities

Beginning January 1, 2016, community public water systems (PWSs) serving fewer than 1,000 people will be assigned the MDH Public Health Laboratory (PHL) in St. Paul for quarterly bacteriological analyses. PWS operators should prepare for logistical changes as well as likely increases in shipping costs and sample rejections.

The MDH PHL will continue to provide sample kits, mailers, and analysis of water samples at no cost. Instructions for sample collection and mailing will be provided. PWS operators will notice a change in sample bottle volume as the PHL transitions to using 150 milliliter (mL), double-fill-line bottles (shown below). However, as before, PWSs are free to choose to use (and pay for) a private, certified laboratory instead of the PHL. In those cases, the chosen labs must have the ability to report results electronically to the MDH.

Overnight shipping will be necessary to ensure samples arrive at the PHL within 24 hours of sample collection so they can be analyzed within the required 30-hour hold time. Shipping costs will continue to be the responsibilities of PWSs. The combination of larger distances from a designated laboratory and faster shipping requirements are expected to increase shipping expenses for these community PWSs.

In addition, sample rejection rates are expected to increase due to samples not meeting the 30-hour hold time. The affected PWSs are encouraged to take the following steps to prepare for this change:

  • Determine a best shipping method that can deliver samples to the MDH PHL within 30 hours.
  • Thoroughly read the MDH PHL chain of custody forms and instructions upon receipt in December 2015.
  • Inspect and become familiar with bottles required for MDH PHL sample collection.
  • Prepare for occasional replacement samples in schedules and budgets.

Minnesota Department of Natural Resources Water Supply Planning

Every 10 years, all public water suppliers in Minnesota that serve more than 1,000 people must have a water supply plan approved by the Department of Natural Resources (DNR). This requirement, in place since the 1990s, is designed to encourage communities to deal proactively with providing sustainable drinking water for citizens, businesses, and industry. Having an approved water supply plan also creates eligibility for funding requests to the Minnesota Department of Health for the Drinking Water Revolving Fund.

The third generation of the plan updates will be due between 2016 and 2018. Starting last October, the DNR has been notifying the 360 water suppliers by email as to when their specific water plan is due. The new DNR Water Supply Plan web page (http://www.mndnr.gov/watersupplyplans) is also available. The DNR will be providing water suppliers with an easy-to-use template and guidelines for completion. Plans will now be submitted electronically through the Minnesota Permitting and Reporting System, where most water use reporting takes place.

The Local Water Supply Plan template has four sections: inventory, emergency planning, water conservation, and metropolitan area (when relevant). The plan includes stronger conservation measures to meet demand reduction requirements.

All communities in the seven-county metropolitan area, even those of fewer than 1,000 people, must also fill out an additional section relating to the Metropolitan Council’s Master Water Supply Plan.

The DNR and Metropolitan Council have been working together to update the template to make it quicker and easier for communities to complete. There are no major changes from the last template, but the format will include more standards for water conservation.

New this year are workshops with neighboring water suppliers to discuss local water supply issues and water conservation strategies. Fourteen workshops were completed in October and early November, and more will be held over the next two years.   “Many areas of Minnesota are blessed with abundant water,” said Carmelita Nelson, DNR water conservation consultant. “However, groundwater resources are not limitless, and in some areas we are hitting the limits. We are seeing more instances where withdrawal is impacting sensitive natural areas, interfering with other wells, or affecting drinking water quality.”

Approximately 75 percent of Minnesotans depend on groundwater for their drinking water. The remaining 25 percent obtain their drinking water from surface sources. “In the last 10 years, groundwater specialists have learned a great deal about aquifers, and we are collectively going through an evolution in the way we look at appropriation and sustainability,” said Steve Thompson, DNR hydrogeologist. “In the past, we have made decisions on well permit requests individually. In the future, we will need to start looking at water appropriation requests cumulatively, using modeling to ensure that wells are sustainable.”

“In next ten years, conserving our drinking water sources will become more and more critical,” added Nelson. “We will all need to implement more water reuse and conservation.”

Closing the Gap on Water System Security

Close the Gap graphic

By Jon Groethe, Minnesota Department of Health

Next year, 2016, will kick off the “Close the Gap” campaign for water-system security. Over the last decade, Minnesota’s water sector has made notable progress toward physically securing much of its critical infrastructure across the state. With the challenges the future may bring, now would be an excellent time to assess the security measures we currently have in place and to explore additional security measures that would raise the bar on our existing physical security—measures that are targeted, effective, and practical.

The Minnesota Department of Health will be renewing its efforts during the upcoming year to encourage and assist Minnesota water systems to close the gap by identifying and improving physical barriers as well as by checking and upgrading security equipment and operational procedures aimed to deter, detect, and respond. We will also be providing updated training and review of response procedures for a variety of unintentional events (severe weather, plant malfunctions, etc.) at our district water schools. Finally, we want to pass along the most recent security and emergency response tools that are currently out there for you to use.

You can help! We want to hear about your ideas and security successes. Together we can compile a clearinghouse of proven and innovative security solutions which in turn can be shared and assimilated across Minnesota’s water sector.

Please contact me with your thoughts and questions at 320-223-7339, jon.groethe@state.mn.us.

Nitrate Source Water Monitoring Beginning in 2016

By David Rindal, Minnesota Department of Health engineer

Beginning January 1, 2016, the MDH Community Public Water Supply Unit will initiate a statewide investigation into nitrate trends for community public water systems (PWS) wells and aquifer sources. Community PWSs with one or more source wells known to have nitrate levels of at least 3.0 milligrams nitrogen per liter (mg-N/L) will be asked to collect investigative quarterly source samples. The information will assist PWSs and MDH with nitrate trend analyses and will also help MDH collaborate with the Minnesota Department of Agriculture in implementation of the state Nitrogen Fertilizer Management Plan.

Analysis of results from the MDH General Water Chemistry Project showed approximately six percent of sampled groundwater sources had nitrate results of at least 3.0 mg-N/L.

That concentration was chosen as the primary criteria due to its association with anthropogenic sources as well as the practicality of monitoring 140 wells per quarter. Over time, the MDH expects that number to change as wells either encounter nitrate issues, are newly identified as having nitrate issues, are sealed and abandoned, or experience improvements in response to remediation or natural processes.

As with most monitoring, the MDH PHL will provide sample kits, mailers, and water sample analyses for free. The main difference from regular compliance monitoring will be the need to collect raw water samples from specific wells rather than finished water samples from designated entry points. Instructions for sample collection and mailing will be provided, although shipping costs will continue to be the responsibilities of PWSs. A row entitled “Source Nitrate” will appear in the 2016 Annual Monitoring Schedule of any community PWS asked to participate in this monitoring, as shown below.

She grew on him like she was a colony of E. coli and he was room temperature Canadian beef.

She walked into my office like a centipede with 98 missing legs.

The revelation that his marriage of 30 years had disintegrated because of his wife’s infidelity came as a rude shock, like a surcharge at a formerly surcharge-free ATM.

The little boat gently drifted across the pond exactly the way a bowling ball wouldn’t.

The red brick was the color of a brick-red crayon.

The lamp just sat there, like an inanimate object.

He was as tall as a six-foot-three-inch tree.
