Paper Versions of Waterline to End in 2007
Beginning with the Summer 2007 issue, a web-only version of the Waterline will be published. The Waterline will contain the same information about upcoming training and regulatory updates as well as other news and feature stories although it will no longer be available in a paper format.

A new issue will be produced and posted to the Minnesota Department of Health (MDH) web site quarterly, and e-mail will be used to notify people when it has been posted on the MDH website. Many operators and others are already receiving a notice when current issues are put on the website.

Feature Story: Blaine Deals with Water Issues with New Plants

Air stripping tower in Blaine
An 60-foot-tall air-stripping tower was lifted and then lowered into place at a new water treatment plant in Blaine on Thursday, July 27. The tower will allow the city to put two wells back into service after more than 10 years of being off-line because of volatile organic chemicals. The tower and plant are part of a series of new water plants and upgrades for the city’s water utility, part of an ongoing effort to keep up with rising water demand because of Blaine’s growth. A second plant is already operational with a third on the way.

An outpost on the northern edge of the Twin Cities when it established a public water system more than 40 years ago, the city of Blaine has seen tremendous growth in its population, which now approaches 50,000. The number of wells to provide water to the increasing number of residents has also grown.

Treatment of the water had been handled at individual wells with the addition of fluoride, chlorine, and a polyphosphate to sequester the manganese and iron in the water. However, aesthetic problems remained for some customers. In addition, 1,2- Dichloroethene was found in two wells, causing them to be taken off line.

The area of these wells with volatile organic chemicals (VOCs) became a Superfund site, and some federal money was made available for the purpose of designing a plant to treat these and other wells. Work on the plant, located off U. S. Hwy. 10 and Central Avenue NE in the southern part of the city, began in September of 2005. A 60-foot-high air-stripping tower will remove the VOCs, and a filter will deal with iron and manganese. This will allow the two wells that were taken out of service 12 years ago to go back on-line when the project is completed in mid-September of 2006.

The continued need for capacity to keep up with the city’s growth, combined with customer complaints about discolored water because of the iron and manganese, led Blaine to plan the construction of other plants. After a series of public informational meetings, the City Council approved a rate increase from 75 cents to $1.10 per 1,000 gallons for the first 24,000 gallons and $1.35 per 1,000 gallons for the next 24,000 gallons.

Construction on another plant, just south of Minn. Hwy. 242 on Oak Park Boulevard, began in January 2005 and went on-line one year later. Designated as Plant No. 2 (the one on Hwy. 10 is Plant No. 1), it serves two already existing wells, which are inside the plant, in addition to a new well that is a block to the east of the plant. As is the case with Plant No. 1, this plant is designed for iron and manganese reduction although it does not have the air-stripping tower for VOCs.

The plants have been and are being designed by Progressive Consulting Engineers, Inc. (PCE) of Brooklyn Center, Minnesota. Naeem Qureshi of PCE said the plants are using a process from Filtronics, Inc. of Anaheim, California, that involves pumping the well water into a chlorine contactor. High doses of chlorine are added to oxidize the iron and manganese. Sulphur dioxide is added as the water enters another contactor to neutralize any taste and odor before going to the filters.

Plant No. 2 has four pressure filters and a capacity of 8 million gallons per day (MGD). Blaine director of public works Mike Ulrich said Filtronics did a pilot study and found that it could reduce iron and manganese down to nondetectable levels with this system. “It’s a compact filter system,” Ulrich added. “It doesn’t require a lot of space. A gravity plant would cost more to build, more to operate, and more to maintain.”

Bids for Plant No. 3, which will be on 103rd Street, near Centennial High School in the southeast part of the city, are now being let. Qureshi says that this plant, which will treat the water from two existing wells, should be completed by September 2007. In addition to the wells with each of the plants, Blaine has several outlying wells that continue to receive treatment through chemical addition at the wellhead. When the wells for Plant No. 1 are put back on-line, Blaine will have 17 wells.

However, the city is not done yet. It recently purchased 10 acres in the area of Lexington Avenue and Anoka County Road J. In the next five to seven years, it plans to construct a 12 MGD plant and a 2 million gallon water tower on the site. Will this be enough? Ulrich isn’t sure. Much depends on the growth of the city, he points out, including whether the Minnesota Vikings build a new stadium in Blaine. While the stadium will not greatly affect water demand by itself, ensuing development around the stadium could have a big impact.

For now, however, those are questions for the future. In the meantime, Ulrich and the citizens are finding relief in the quality and quantity they are receiving because of the new plants.
