Des Moines, IA – An Iowa environmental advocacy group is urging state lawmakers to enact tougher protections for the state's drinking water, after high levels of blue-green algae were found in the Des Moines water supply. Staff from the Des Moines Water Works traced cyanobacterial blooms in the Racoon River to Black Hawk Lake, 100 miles north.

Susan Heathcote, water program director for the Iowa Environmental Council, says, although the water in Des Moines is safe to drink when treated, that type of algae can make for smelly and bad-tasting water, even at low levels. Her biggest concern is that, at high levels, the toxins can cause serious health problems. The Department of Natural Resources (DNR), she says, currently has no state programs dealing with the sources of pollution in these large watersheds.

"That needs to become more of a priority, because these issues are not going away. They're getting worse and new problems are surfacing every day. The department needs to partner with drinking water utilities in developing programs that will help address these sources of pollution within their watersheds, that are really outside of the control of the drinking water utilities way downstream."

Randy Beavers, Des Moines Water Works interim CEO and general manager, says the cyanobacterial organism needs nutrients to survive, and right now the river's source waters have plenty to feed it.

"In August, we were seeing cell counts of over 30,000 in the river and our experience has been that once cell counts get above 10,000, it becomes problematic for treatment. We always have the potential for taste and odor issues as well. It has just been within the last week that we've seen the cell counts fall below 10,000."

Heathcote says they're not trying to create panic; Des Moines drinking water is treated by state-of-the art equipment and is safe to drink. But, she says, more needs to be learned about these bacteria.

The Des Moines Water Works has been switching the water they draw from the Raccoon River to a secondary source on the Des Moines River.

Twenty-one counties in New York are under a drought watch, which could become the norm as climate change heats up the planet.

According to the New York State Department of Environmental Conservation, a drought watch is the least severe on the drought monitoring scale. For now, public water suppliers start conserving water and urge people to reduce their water use.

The National Integrated Drought Information System classifies this as a moderate drought. Sylvia Reeves, the system's Northeast regional drought information coordinator, said these "pop-up droughts" have been typical in the last two years, in the entire Northeast.

"We've seen more frequent drought events that have lasted anywhere from six months to a little over a year," she said. "And, those events typically have come on in what we call a 'flashy' form - rapid onset of drought conditions and rapid intensification."

Reeves added that if several different indicators of groundwater, surface water and wells don't change, drought conditions could be upgraded to "severe." That's what New York faced in summer and mid-fall 2020. These conditions aren't generally bad enough to cause wildfires, but grass and brush fires could be forces to contend with.

During droughts, it isn't just about needing water for small things such as brushing your teeth or doing laundry. It's about making sure vital crops are irrigated thoroughly and having a decent supply of groundwater.

As weather gets more extreme, droughts could be more prolonged, said Alison Branco, director of climate adaptation for The Nature Conservancy of Long Island.

"What we're going to see is, not a huge change in the overall amount of rain we receive - a little increase, but not a ton," she said. "But it's going to come in less frequent, more severe bursts; like big heavy storms and not so much like that slow, steady rain."

She added that there could be periods of drought between rain events, but groundwater sources won't be able to replenish as quickly. Branco, a Long Island resident, said she feels the infrastructure to pump groundwater isn't equipped to meet the high demands a drought would create. However, she said, New York is not at risk of the kinds of lengthy droughts seen in California and other Western states.

If Iowa wants to ensure its Nutrient Reduction Strategy is working to curb farm runoff, a new report from an environmental group says it needs to do a better job of monitoring water quality around the state.

The Iowa Environmental Council noted that since 2013, Iowa has committed nearly $100 million toward water-quality projects. That includes keeping an eye on the amount of nitrogen and phosphorus entering waterways from sources such as agriculture. Despite the investments, said Alicia Vasto, associate director of the council's water program, agencies involved have yet to implement an approach to see if the efforts actually are improving the water.

"We believe that if there was monitoring, if there was more information available, that it would demonstrate current efforts are not where they need to be and we need to adjust the strategy," she said.

The report recommended collaboration on a monitoring framework that would include tools such as in-stream sensors, and the results made available to the public. In a move aligned with other states along the Mississippi River, the reduction strategy seeks at least a 45% reduction in total nitrogen and phosphorus loads.

The state departments of Natural Resources and Agriculture did not provide comments for this report before deadline.

While groups such as hers push for more information, Vasto said there are signs that Iowa's water-quality situation is getting worse. This includes more algae blooms that make the water less safe for recreation.

"It just kind of lowers the average quality of life for Iowans that we can't go out and access and enjoy our public waterways," she said, "because there's this pollution that is making them toxic."

A 2018 study by the University of Iowa found a nearly 50% increase over two decades in the amount of nitrogen pollution flowing from the state to the Gulf of Mexico. Last year, state lawmakers passed a major extension of funding for its strategy, but Vasto said unless monitoring improves, that money could be going to waste.

Water experts will gather next week in Nashville to talk about the state of stream restoration, at the first national stream restoration conference.

Tennessee's heavy agricultural economy means the state's waterways are at risk for increased sediment.

Ken White, chair of the stream restoration nonprofit Resource Institute, said implementing strategies to reduce sediment and restore natural flow to streams improves water quality, wildlife habitat and outdoor recreation.

"More sediment in the rivers is not good," White explained. "Because every city and county or municipal organization that supplies clean water to a community, they have to pay for more chemicals, it's harder to clean the water for everybody to use for cooking, drinking, bathing."

Experts will discuss urban and rural restoration, dam removal, construction, flood plain reconnection, and habitat improvement.

Adam Williams, president of Brushy Fork Environmental Consulting, said residents are increasingly aware of the link between healthy water and reducing erosion and sedimentation, and are feeling the effects of climate-related flooding and extreme weather on local waterways.

"Meeting landowners, knocking on doors and finding willing landowners to participate in grant-funded work," Williams outlined. "Putting in riparian buffers, explaining to residential, commercial, agricultural landowners in ways to use best management practices to stabilize their creeks."

White added stream restoration can improve community health, increase property values and spur local economic activity.

"We don't even hesitate to buy sunscreen before we go to the beach, or we're out in the sun," White noted. "The more we can educate water professionals, in order to have quality water for decades to come, we're gonna have to do a better job of being good stewards and managing what we have now."

According to the Environmental Protection Agency, more than half of rivers and streams in Tennessee are considered impaired.
