Reservoir Photo Wins Award The draining of a Minneapolis Water Works reservoir for repairs presented a unique photo opportunity in 1993. The new editor of the Waterline did a story on the reservoir and five years later entered one of the photos in a National Photography Contest co-sponsored by the Centers for Disease Control as part of National Public Health Week. The photo won the grand prize, and the Waterline editor was invited to a press conference in Washington, D.C., to accept the award from Surgeon General David Satcher (below—Satcher at left, editor at right). MDH Contracts with MRWA for Technical Assistance The drinking water revolving loan fund authorizes states to set aside money from the capitalization grant to fund various components of the drinking water program. One of those fundable components is technical assistance to small systems. The Minnesota Department of Health (MDH) will be taking advantage of the technical assistance set aside to fund a technical assistance program for nonmunicipal community water systems, which include manufactured housing developments, housing subdivisions, and apartment buildings. This assistance will be provided through a contract with the Minnesota Rural Water Association (MRWA). Through this contract MRWA—which has hired Don Christianson, the former water superintendent a t Crookston, to carry out the duties— will schedule and conduct one-on-one technical assistance visits to help systems with operational, maintenance, and managerial problems related to the water system. They will also be available to provide assistance by phone or through literature concerning operational issues. MRWA will also disseminate information about the requirements of the Safe Drinking Water Act but will NOT serve as a compliance or enforcement agent of MDH.

Amid indications that a change in season might be appropriate for the school, a survey was conducted among participants at the 1998 event; the results clearly showed that April was still the preferred time for the school, so April it will remain. It is possible that the one-day Exam Prep session that has preceded the Metro School will now be integrated into the school rather than held as a separate event. (See related story on this page for more news regarding training surveys.) The Northeast District has also set plans for its 1999 school. After a two-year stint at the Holiday Inn SunSpree in Ely, the school—which will run from Wednesday, May 5 through Friday, May 7—will move to Superior Shores Resort and Conference Center in Two Harbors. The next American Water Works Association—scheduled for Thursday, October 22 at the Earle Brown Center in St. Paul and in East Grand Forks—will be of interest to the water systems affected by new risk management regulations that were adopted under the Clean Air Act in 1996. Systems that handle threshold amounts of chlorine, anhydrous ammonia, or aqueous ammonia will be required to develop and implement a comprehensive risk management plan by July of 1999. Information will be sent to all AWWA members on this teleconference; in addition, an application will be in the Fall 1998 Waterline. AWWA has also set its 1999 teleconference schedule: March 11—Complying with the D/DBP Rule Cluster Regulations October 21—Technologies to Comply with the D/DBP Rule Cluster Surveys Yield Valuable Information AWWA 1998-99 District Officers Surveys related to safety and general training have been conducted in the AWWA Metro District. Last January, 67 metro area water superintendents who responded to a survey indicated that they would be interested in having the district sponsor half- or full-day training sessions that dealt with only one or two topics at a time. The topics they expressed the greatest interest in were Water Treatment (Basic and Advanced), Water Chemistry, SCADA Systems, Chemical Feed, Wells, and Leadership/Interpersonal Skills. The superintendents also showed a clear desire for additional safety training. As a result, a separate safety survey was distributed to all participants at the three-day Metro School in April. The majority who responded to this survey said that although they do receive adequate training opportunities for required safety topics, they felt a need for additional, optional safety training. The Metro District Education Committee will consider the results of the surveys and explore ways of delivering the desired training.

Recent actions (as well as the possibility of inaction) by the U. S. Environmental Protection Agency (EPA) concerning the revisions to the radionuclide rule could have a major impact on Minnesota community water systems. On July 18, 1991, EPA had proposed revisions to the radionuclide rule, the most significant being a change in maximum contaminant levels (MCLs) for radium 226 and radium 228. Prior to the proposed rule revision, the MCL for the total of radium 226 and radium 228 was 5 picoCuries/liter (pCi/l). The 1991 rule revision proposed to change the MCL to 20 pCi/l for radium 226 and 20 pCi/l for radium 228. Radium 226 and 228 are naturally occurring minerals that are commonly found in Minnesota groundwater that is drawn from deeper bedrock aquifers. EPA indicated to MDH that during the time frame between when the rule was proposed in July of 1991 and when it became final (a period that is usually no more than two years), MDH should not require any corrective actions from Minnesota water systems that complied with the proposed MCLs of 20 pCi/l for radium 226 and 20 pCi/l for radium 228. This was good news since none of the Minnesota systems exceeded the proposed MCLs. MDH felt that it was reasonable to take this a step further and decided to require increased quarterly radium monitoring only if the 20/20 MCL was exceeded during routine sampling (which was once every three years). Since 1991 there have been no exceedances during routine monitoring of the 20/20 MCLs, so MDH has not initiated any quarterly compliance monitoring for radium. For a variety of reasons, nothing was done to finalize the 1991 rule revision proposal; as a result, MDH continued to use the 20/20 proposal as the MCLs to base monitoring and compliance decisions on. However, in December 1997, EPA held a stakeholder’s meeting to discuss issues related to adopting a revised radionuclide rule and announced that the radium MCLs will probably not be changed to the 20/20 as proposed in 1991 but would remain at a combined radium level of 5 pCi/l. EPA officials cited provisions of the 1996 Safe Drinking Water Act amendments that prevent them from lowering protection by reducing the radium MCL even though they acknowledged that a looser limit would present the same health risk as intended by the current (5 pCi/l) one. MDH was stunned by this announcement and even more confused by EPA’s rationale for not changing the MCLs to 20/20 even though they admitted that by considering current health risk information they could justify a less stringent MCL than the combined 5 pCi/l. Close on the heels of this revelation from EPA headquarters came word from the EPA Region 5 office that rescinded the earlier agreement with MDH that allowed for increased monitoring based on comparing routine sample results with the proposed 20/20 MCLs. Region 5 insisted that MDH immediately begin requiring quarterly compliance monitoring for all Minnesota community systems where routine radium results exceeded 5pCi/l. MDH was opposed to this and contended that it should wait until the rule has been formally revised to remove the uncertainty of not knowing what MCLs a water system will actually have to comply with. EPA Region 5 rejected this approach and insisted that MDH begin quarterly monitoring Drinking Water Report Again Reveals Good News “So who needs bottled water?” was the lead sentence in a May 6, 1998 article in the St. Paul Pioneer Press regarding the annual report on drinking water quality in Minnesota issued by the Minnesota Department of Health. The Pioneer Press story continued, “Tests conducted in Minnesota last year suggest health-conscious consumers could do their budgets a favor and rely on that old stand-by, tap water.” MDH Commissioner Anne Barry announced the results of 1997 monitoring of the state’s community water supplies while addressing participants at the Minnesota Water ‘98 conference in Minneapolis on May 5. “Like our previous drinking water reports, this latest report offers a highly reassuring picture of our state’s drinking water infrastructure,” Barry said. “Once again, we rarely found detectable levels of contamination—and violations of applicable state or federal drinking water standards were rarer still. And whenever problems were discovered, we quickly took action to prevent any potential health problems. “In short, the problems we found were minimal—and the system worked. Based on this report, we believe that the people of Minnesota can continue to have confidence in the high quality and safety of their drinking water.” Barry also heralded the efforts of Minnesota water operators in the minimal disruption of drinking water supply during two natural disasters—the tornadoes in southern Minnesota and the 1997 floods—over the past 14 months. at all systems exceeding 5 pCi/l. EPA Region 5 also indicated if MDH was unwilling to proceed in this manner, EPA could take actions directly against the water systems; it could also delay Minnesota’s drinking water revolving fund grant. Faced with these prospects, MDH capitulated and agreed to begin quarterly monitoring beginning in July 1998 at the approximately 50 water systems that had one sample radium result in exceedance of 5 pCi/l. A meeting of the affected community water systems was held on June 10 to inform the water systems of the situation and describe the monitoring that will take place during the next year. A representative from EPA Region 5 was in attendance to present EPA’s position on the issue. MDH encouraged the affected water systems to contact directly EPA Headquarters and request that the rule be reproposed so that full consideration can be given to health risk considerations and also the magnitude of the costs associated with having to meet a combined radium MCL of 5pCi/l. The only treatment method available to reduce radium is softening— either ion exchange or lime—which can be very expensive, especially for those cities with multiple wells or treatment plants. MDH is hopeful that if enough Minnesota water systems contact EPA with their concerns, the radionuclide rule will be reopened and more thoughtful consideration can be given to the health risk of radium versus the costs of treatment. 3 Water Supply East—New York City This year marks the 100th anniversary of New York City as we now know it. In 1898, New York (already the largest city in the nation even though it consisted of barely more than the island of Manhattan) was consolidated with Brooklyn (then the nation’s third largest city) and nearly 40 other townships and communities to form a new city, divided into five boroughs, that brought an increased demand for a variety of services, none more important than an adequate supply of potable water. New York continues as America’s largest city and, as such, has the nation’s largest drinking water system. But while New Yorkers fret about bridges and subways and other worries dealing with an aging and crumbling infrastructure, they continue to draw water from taps with little thought of where it comes from. “Although the city’s water supply is one of its major wonders, probably it is among all of them the least remarked, partly because it is largely hidden from view and even more on account of its trifling cost,” wrote Arthur Warner in a 1932 feature in the New York Times Magazine. “With the natural metropolitan tendency to respect only that which is expensive, the average citizen does not pause to consider a product which costs three-fourths of a cent a day.” Such complacency is not unique to New York. But the sheer magnitude of this city’s drinking water supply, treatment, and distribution process merits a closer look. New York City now draws its drinking water from three upstate During the 1600s, when most of the city’s population lived in lower Manhattan, residents drew their water from local watersheds—the Delaware System, the Catskill System, and the Croton System—to serve more than nine-million residents. wells, streams, and ponds, including a 48-acre, spring-fed pond known as the Collect.

In 1803, the city began (approximately 100 miles to the northwest) and to create new filling the Collect and placing greater reliance on underground reservoirs by damming streams and rivers.

Croton Aqueduct. 4 Acr oss the the USA West—Arizona Toward the other end of the contiguous United States from New York City is an area whose challenges lie not in the magnitude of the population it must serve but in the paucity of the water it has to supply them. In terms of year-round residents, Arizona ranks in the lower half of the fifty states, although its population swells each winter with the onslaught of northern residents escaping harsh climates and in the summer with the hordes of tourists who come to enjoy the state’s scenic natural treasures. No landmark in Arizona receives more visitors than the Grand Canyon. There is no natural source of drinking water on the south rim of the Grand Canyon, even though it is this side that attracts 90 percent of the visitors. The rock layers don’t trap water close enough to the surface to successfully drill wells. Water was supplied in different ways over the years, including transport by train. In 1970, a 14-mile trans-Canyon pipeline was completed, bringing water from Roaring Springs on the north side of the Canyon. Large tanks store more than 13 million gallons to serve the park, which uses over 600,000 gallons daily. One mile south of the Grand Canyon’s south entrance is Tusayan, a community of hotels and visitor amenities. One of the hotels has been successful in drilling for water although, for the most part, adequate water is still not available to the 144-acre community, and most of the major hotels have their water hauled by truck from cities to the south. Approximately 130 miles southeast of the Grand Canyon is evidence of how inhabitants drew water from the arid surroundings hundreds of years ago. A limestone sinkhole, 470 feet wide and 55 feet deep, rimmed by pueblos and cliff dwellings, was a source of water to the fields of ancient peoples. Fed by continuously flowing springs, Montezuma Well, as the sinkhole is called, was formed long ago by the collapse of an immense underground cavern. Both the Hohokam and Sinagua irrigated crops with the sinkhole’s waters, and traces of irrigation ditches dug during the 1200s—and now thickly coated with lime—are still visible to visitors. The National Park Service, which now administers the site, says Montezuma Well has “all the surprise of a lake and fairly lush vegetation in the midst of desert.” Montezuma Well was a water source for ancient cultures. Water is piped 14 miles from Roaring Springs to the Grand Canyon’s south rim. 5 Roaring Springs Conversion of Test Wells No Longer Allowed Waterworks Operators Quiz 1. Cathodic protection means protection against: a. contamination. b. corrosion. c. hardness. d. infiltration. In the past, communities have drilled “test wells” that were not pre-approved by MDH and then converted them to community drinking water supplies. Beginning July 1, 1998, MDH will not allow the conversion of test wells into community water supply wells. If there is a chance that a well will be used as a community water supply, the following steps must be followed: • The plans and specifications for the well(s) must be approved before the well construction begins. • A wellhead protection area preliminary delineation worksheet must be submitted to the department. • A well notification identifying the well as a community public water supply well must be provided to the Well Management Section at MDH. • An emergency and water conservation plan must be approved by the Minnesota Department of Natural Resources. Questions regarding any of these matters may be directed to Michael Convery at 612/215-0818. 2. The maximum contaminant level goal of known or probable carcinogens is: a. set by the state. b. the same as the maximum contaminant level. c. zero. d. the minimum detectable level of a given contaminant. 3.

In addition, the Attorney General’s office recently collected $826 in penalties and fees from Tamarack Court, Inc., PWS 1730058 for failure to perform bacteriological, nitrate, and lead and copper sampling. Nitrate Situation Offers Opportunity for Multi-Agency Solutions On the heels of an exceedance of the maximum contaminant level for nitrate in southwestern Minnesota last summer, the Minnesota Department of Health convened an interagency workgroup to go beyond dealing with just the exceedance and to study the larger problem of nitrate nitrogen contamination in drinking water. Chaired by Bruce Olsen of MDH, the workgroup contains representatives from the Minnesota Department of Agriculture, Minnesota Pollution Control Agency (MPCA), Board of Water and Soil Resources, and Minnesota Department of Natural Resources (DNR). The group considered and recommended a multipronged approach with strategies ranging from wellhead protection to best management practices in addressing the nitrate situation in the well fields operated by the LincolnPipestone Rural Water Supply District (LPRWSD). Lincoln-Pipestone Rural Water The LPRWSD—which serves 24 communities and more than 2,800 farms—operates three well fields (Holland, Verdi, and Burr), two of which are deemed vulnerable to nitrate contamination. The Holland well field, in Pipestone County, has five wells that pump out of an unconfined sand and gravel aquifer. At the land surface is an old stream channel, a trench carved into clay and backfilled with sand and gravel (a common phenomenon in southwest Minnesota). “It can yield lots of water but is vulnerable,” says Olsen. Nitrate levels found in water pumped from the Holland well field exceeded the maximum contaminant level of 10 parts per million (MCL). Water from the Verdi well field had nitrate levels approaching, but not exceeding, the MCL. The LPRWSD operates five wells in the Verdi field that pump from a sand and gravel aquifer that may exhibit semi-confined to unconfined hydraulic conditions depending on the local geological setting. The Burr well field is a better source in terms of protection from nitrate contamination; however, pumping from the Burr well field affects wetlands in Minnesota and South Dakota. “New water supplies are hard to find in this part of the state,” Olsen says. Sources Facing these challenges, the work group sought to identify management strategies for reducing nitrate levels in the Holland and Verdi well fields with the understanding that, although similarities exist between potential nitrate sources for the two fields, differences in soil and geologic conditions as well as land use would likely lead to differing strategies. In addition, much less was known about the Holland well field than the Verdi well field, where the work group was able to better define potential sources of nitrate nitrogen that could be affecting the well fields by using existing agency data and a survey of land owners in Verdi Township that had been conducted by the Department of Agriculture. No inventory exists of abandoned feedlots for the watershed area around the Holland well field, which includes dairy and beef cattle yards that do not require a feedlot permit from the Pollution Control Agency (although one is now being prepared in addition to a survey of property owners). In addition, current practices regarding application of commercial fertilizer to fields are not known. Recommendations Armed with this information (or lack of information) the workgroup identified several strategies they felt could help to reduce nitrate levels. The strategies include the following: Feedlot Management and Permitting—This would involve MDH and MPCA cooperation on feedlot permitting in geographically vulnerable wellhead protection areas, a strategy that addresses concerns over animal confinement facilities and manure spreading of fields and one that can be applied to new or amended permits once the wellhead protection areas for these fields have been delineated. State Groundwater Appropriations Permitting Program—The DNR can use the water appropriations program to limit groundwater withdrawals where pumping causes surface water or groundwater containing elevated nitrate levels to enter public water supply wells. New high-capacity wells must be evaluated for their potential to cause the movement of nitrate into groundwater resources that are used as a drinking water supply. Best Management Practices regarding Nutrient and Nitrogen Management—Interviews with growers in Verdi Township and within the St. Peter wellhead protection area in Nicollet County demonstrated that nitrogen application can be reduced without major yield reductions. The Department of Agriculture will be working with the University of Minnesota to review best management practices for shallow soils overlying shallow groundwater in this part of the state, a long-term strategy that may reduce nitrate contamination resulting from crop production. In addition, the Department of Agriculture and Minnesota Extension Service will notify businesses which provide commercial fertilizer about best management practices (BMPs) for the soils that are present in the Holland and Verdi well fields. If BMPs are not followed and water quality is unacceptable, the Department of Agriculture will issue a water resource protection requirement and BMPs will be enforceable. Bruce Olsen noted that wellhead protection is being used to address nitrate situations with several water systems in the southwestern part of the state. He says that land owners are being very cooperative about altering their practices and even taking some land out of production. “Land owners are definitely the solution, not the problem,” Olsen concludes. Between earth and earth’s atmosphere, the amount of water remains constant; there is never a drop more, never a drop less. This is a story of circular infinity, of a planet birthing itself. —Linda Hogan 7 CALENDAR Minnesota Section, American Water Works Association Annual Conference, September 2325, Rochester, Contact Jim Haugen, 612/ 489-1051 *October 15, Southwest Waterworks Operators’ School, Windom, Contact Mark Sweers, 507/389-2501 *October 28, Central Water Operators’ School, St. John’s University, Collegeville, Contact Duane Johnson, 320/255-7225 *October 30, Southeast Water Operators’ School, Northfield, Contact Paul Halvorson, 507/285-7289 *December 1-3, Northwest Water Operators’ School, Red River Inn, Moorhead, Contact Stew Thornley, 612/ 215-0771 *Suburban Superintendents School October 6, Brooklyn Center Civic Center, Contact John Hill, 612/531-1166 AWWA Teleconference October 22, Risk Management, Contact Stew Thornley, 612/215-0771 American Water Works Association October 6, Consumer Confidence Reports, Contact Mayme Larson, 303/ 347-6204 or Stew Thornley, 612/2150771 *Schools/meetings marked with an asterisk include a certification exam Minnesota Rural Water Association Contact Kyle Kedrowski, 218/685-5197 June 3, Operation and Maintenance, Mantorville June 17, Operation and Maintenance, Middle River *September 2, Operation and Maintenance, Askov September 16, Operation and Maintenance, Fulda September 30, Operation and Maintenance, Twin Valley October 7, Operation and Maintenance, Coleraine October 13, OSHA Safety, Morris October 14, OSHA Safety, St. Cloud October 14, Operations for Nonmunicipal Systems, Cass Lake October 20, OSHA Safety, Grand Rapids October 21, OSHA Safety, Hinckley November 4, Operations for Nonmunicipal Systems, St. Peter November 17, Risk Reduction in Public Utilities, Marshall November 18, Risk Reduction in Public Utilities, Alexandria December 9, Winterizing Your Water System, Bemidji December 10, Winterizing Your Water System, Eveleth December 15, Securing Financing for Small Systems, Duluth December 16, Securing Financing for Small Systems, Belle Plaine Minnesota Department of Health 121 E. 7th Place Suite 220 P.
