Water Quality

Rivers are a vital part of Iowa's ecosystem.

“Rivers in Iowa are the most important corridors of habitat, the ribbons of habitat, that we have left," says  wildlife biologist Jim Pease.

Over the past four summers Pease has paddled 1800 miles of Iowa rivers. On these trips he’s learned a lot about habitat, water quality, and human impact on the water ways. 

  A federal judge has dismissed The Des Moines Water Works lawsuit against three counties, claiming their agricultural drainage districts have been sending nitrate pollution into the rivers the water utility uses for drinking water. The lawsuit has been a hot button issue across Iowa and country because if the utility had been successful it could have regulated farming.

The lawsuit has been a hot button issue across Iowa and country because if the utility had been successful it could have regulated farming.

A bill in the Iowa legislature would break up the Des Moines Water Works board and replace it with a regional water authority. Those who support the bill say it will update a 100-year-old system for delivering water to the growing metro and its suburbs. Critics say the bill is really about stopping a controversial lawsuit from the Des Moines Water Works targeting large scale agriculture.

An Iowa Supreme Court ruling has found that 10 drainage districts northwest of Des Moines are not liable for potentially millions of dollars in damages. Des Moines's water utility brought the case in a novel attempt to sue other government entities for monetary damages.

The frequency of severe flooding events in Iowa is increasing. Data from Iowa State University shows that 100-year flood plain maps really map 25-year flood plains, and in cities like Cedar Rapids, large rainfall events have increased by 56 percent.  

Kamyar Enshayan, director of the University of Northern Iowa Center for Energy and Environmental Education, says that’s in part due to land use.

Farming in the fertile Midwest is tied to an environmental disaster in the Gulf of Mexico. But scientists are studying new ways to lessen the Midwest's environmental impact and improve water quality.

The National Oceanic and Atmospheric Administration (NOAA) forecasts the so-called "dead zone," an area of sea without enough oxygen to support most marine life, to grow larger than the size of Connecticut, or roughly 6,000 square miles.  

Standing on a platform above the eastern bank of the Missouri River at the Kansas City, Missouri, Water Services intake plant is like being on the deck of a large ship.

Electric turbines create a vibration along the blue railing, where David Greene, laboratory manager for Kansas City Water Services, looks out across the river. Water the color of chocolate milk is sucked up and forced through screens below, picking up all the debris the river carries downstream.  

On a gray day, just as the rain begins to fall, Roger Zylstra stops his red GMC Sierra pick-up truck on the side of the road and hops down into a ditch in Jasper County, Iowa. It takes two such stops before he unearths amid the tall weeds and grasses what he’s looking for.

"Here is one of the tiles," he says, pointing to a pipe about six or eight inches in diameter. Water trickles from it into a culvert that runs under the road after flowing through a network of underground drainage lines below his farm field. "That's where it outlets."

Living in the Platte River Valley in central Nebraska means understanding that the water in your well may contain high levels of nitrates and may not be safe to drink.

"When our first son was born in 1980, we actually put a distiller in for our drinking water here in the house," says Ken Seim, who lives in the Platte Valley near the town of Chapman, Nebraska. "And at that time our water level was 12 parts per million."

Contaminated drinking water isn't just a problem for Flint, Michigan. Many towns and cities across the Midwest and Great Plains face pollution seeping into their water supplies. A big part of the problem: farming and ranching.

There’s been a lot of talk in Iowa about water quality. From failed attempts by the legislature and the governor to come up with new funding, to the state’s largest water utility suing three rural boards of supervisors in northwest Iowa. That area of the state is part of a region called the “prairie pothole”. It stretches from Canada, down through the Dakotas, northern Montana and western Minnesota as well.

In North Dakota, much of this habitat is still intact and conservationists are concerned about the health implications of a landscape looking more like Iowa.

What happened in Flint, Michigan is only one of several high profile incidents of public health crises arising from drinking water contamination. In fact, according to Siddhartha Roy, who was part of the team that discovered high lead levels in Flint, “There are millions of lead pipes,” and “we have them in virtually every city in the U.S.”

The Iowa Department of Natural Resources is expecting another summer boating season full of toxic, blue green algae blooms. There were a record number of beach closures in 2015 in Iowa, and the DNR is expecting this year to be the same or worse. 

The blooms release microcystin, which is a toxin released by cyanobacteria. The toxin can kill pets and cause rashes and flu like symptoms in humans.

As the weather heats up this week, Mary Skopec, beach monitoring coordinator for the Iowa DNR, says that we’ll likely start to see algal blooms that lead to beach closures.

Iowa Lawmakers, farmers and environmentalists continue to debate the best way to curb water quality issues, following an unsuccessful attempt to fund more projects this legislative session.

A state cost share program designed to help Iowa farmers install nutrient reduction practices on their farm is entering its fourth year.  Lawmakers and the governor struggled this legislative session to come up with a way to spend more money on water quality in the state. In the last three years, the state has awarded $12 million on 45 different projects.

First established in 1970, Earth Day is celebrated worldwide on April 22nd every year to celebrate and support the protection of the environment. Has it worked?

Ralph Rosenberg, Executive Director of the Iowa Environmental Council, says Earth Day has evolved from raising awareness, to sparking action, to returning results.

"There's an urgency now," says Rosenberg. "People have seen some progress in 46 years, but we do need to see awareness and action year-round."
