Des Moines Water Works turned on the world’s largest nitrate-removal facility Friday for the first time since 2007 after levels of health-threatening nitrates hit records in both the Des Moines and Raccoon rivers, two main drinking-water sources.
Bill Stowe, the utility’s general manager, said the process will keep nitrates at safe levels in tap water, but he is concerned about the rising costs and difficulty of treating water as nitrate levels climb.
The $4 million nitrate-removal plant, installed in 1992, costs about $7,000 a day to run. So far, the utility is using four of the eight treatment cells where nitrates are stripped from the water. The Environmental Protection Agency had ordered Des Moines to act to remove nitrates after the contaminant exceeded the federal limit in tap water during the early 1990s.
The predicament shows that voluntary conservation efforts on farms aren’t working and do not bode well for the future of the area’s water supply, Stowe said. He added that nitrates, which also occur naturally, primarily come from crop fertilizer. Better field drainage systems have worsened the situation.
Typically, when nitrates rise in the Raccoon River, the Des Moines River remains well within drinking standards. The utility then dilutes the pollution from the Raccoon water with that drawn from the Des Moines.
This time, they are both at record highs — a troubling oddity, Stowe said.
”We are off our playing field,” he said. “We haven’t seen this before.”
Untreated high levels of nitrates in drinking water have been linked to blue baby syndrome, as well as to various cancers and miscarriages. The federal limit is 10 milligrams per liter nitrate in drinking water; both rivers have posted readings in the range of 20 milligrams per liter.
The Raccoon River hit 24 milligrams per liter this week; the previous record was 22. The Des Moines was just under 18; the record was 14.2.
Stowe said some U.S. Geological Survey gauges couldn’t measure the concentrations because they exceeded the meter’s range.
With decades’ worth of data suggesting nitrates are rising in Midwestern rivers, Stowe hopes the situation doesn’t worsen.
Agriculture Secretary Bill Northey said the fact that Water Works didn’t need the removal system for the past six years shows that nitrates have been at manageable levels. He added that nitrates left over from last year, when a smaller than usual corn crop didn’t use as much nitrogen, and the record April rains could have caused a temporary spike.
Northey said strategy now focuses more on reducing nitrogen and phosphorus levels than past efforts, which were targeted mostly on soil conservation.
Laurie Johns, spokeswoman for the Iowa Farm Bureau Federation, said regulations wouldn’t work because farm conditions vary and are best addressed by farmers’ voluntary efforts. No regulation can control record rain, she added.
”With such wild weather swings and 95 percent of Iowa’s land comprised of farmland, there’s not one regulation that would have prevented the current spike in nitrates, short of outlawing crop production in Iowa,” Johns said.
Deborah Neustadt, chairwoman of the Iowa chapter of the Sierra Club, said farmers should be required to have nutrient-management plans featuring specific practices meant to curb runoff. That way, they could be held accountable for pollution from their operations.
“Why does the rate-payer have to pay for actions of farmers?” Neustadt asked.
Susan Heathcote, water program director of the Iowa Environmental Council, took a similar view. “Local pollution-reduction goals are critical to motivating Iowa farmers and landowners to make the significant changes necessary to ensure clean water,” she said.Read More
The Natural Resources Conservation Service (NRCS) will provide $35 million in financial assistance to farmers and ranchers to implement conservation systems to improve water quality in 165 small watersheds through its 2013 National Water Quality Initiative.
Please share this news with your networks so they can consult with their 319 coordinators, reach out to state conservationists or county NRCS service center, or coordinate with their local conservation districts to act on this immediate opportunity.
Applications for funding consideration during fiscal year 2013 must be received by Friday, July 12, 2013, and eligible projects may work to reduce nitrogen, phosphorus, sediment and pathogen contributions from agricultural land. Please note that although the deadline mentions July, we have learned that some states seem to have deadlines in May. Drinking water is mentioned in the announcement as follows, “Communities benefit by having clean waterways, safer drinking water and healthy habitat for fish and wildlife.”Read More
It’s not too late to register for this free webcast on May 1, 2013, from 1:00 to 3:00 pm Eastern time on “Using Social Indicators for Watershed Management Projects.” Working with landowners and managers to find effective and practical solutions to water quality problems is critical to achieving environmental goals. Social indicators provide information about the social context, awareness, attitudes, capacities, constraints, and behaviors in a watershed or project area. Using social indicators can help resource managers and conservation professionals understand target audiences, select effective interventions and evaluate their impacts. At the end of this webcast, participants will understand some basic concepts of behavior change can have the tools to use a framework for using social indicators in nonpoint source management work.

At its April 22nd member meeting, the Source Water Collaborative (SWC) expanded its membership to 25 organizations by welcoming Smart Growth America and the National Association of Conservation Districts (NACD).
The National Association of Conservation Districts (NACD) is the nonprofit organization that represents America’s 3,000 conservation districts and those who serve on their governing boards. Conservation districts are local units of government established under state law to carry out natural resource management programs at the local level. Districts work with millions of cooperating landowners and operators to help them manage and protect land and water resources on all private lands and many public lands in the United States.
“If we truly want to have a long-term impact on the quality of our water resources nationwide, it is critical that we build strong, diverse partnerships at local, state and federal levels,” said NACD CEO John Larson. “This is why we’re so pleased to be joining efforts with the Source Water Collaborative. We recognize that being part of a larger group that advocates and works to achieve the same overall outcomes is essential in these fiscally challenging times, and we look forward to a strong and productive partnership in the years ahead as we focus together on addressing commonsense and meaningful actions to improve water quality across the landscape.”
Since 2001, Smart Growth America has worked in coalitions to make the case for the environmental, social, and economic benefits of smart growth. Smart growth is very simply defined as rural, urban and suburban places with transportation and housing choices near jobs, shops and schools. The strategies communities use to create these places are ideal tools for identifying and protecting environmentally sensitive areas while promoting healthy economic growth.
“We are working with local governments across the country that are re-examining the real costs and benefits of development. They are motivated to reduce costs and protect their assets, but they still need tools and support. We are eager to ‘jump in,’ so to speak, and work with the Source Water Collaborative to make the case for source protection and to more widely distribute all of our organization’s great resources,” said Geoff Anderson, president of Smart Growth America.
The SWC was originally formed in 2006 with the goal to combine the strengths and tools of a diverse set of member organizations to act now and protect drinking water sources for generations to come. More information about the SWC’s members and resources is available on the SWC website at www.sourcewatercollaborative.orgRead More
