The Trump administration’s proposed rollback of the 2015 Clean Water Rule would reduce federal jurisdiction over wetlands, streams and other small water bodies on Iowa farmland. Some Iowans see the proposal, officially made in mid-December, as a win for farmers, while others see it as a hit to much needed water quality regulation in the state.

Since the start of his term, Pres. Trump has wanted to limit Obama’s 2015 Clean Water Rule, which more clearly defined “Waters of the United States” within the Clean Water Act of 1972. This increased the protected area by about 3 percent (according to an op-ed from Bloomberg News) by adding more streams and neighboring wetlands, ponds and impoundments into federal jurisdiction and reducing those waterbodies that could once be given/denied protection on a “case-by-case” basis.

The current administration proposes removing wetlands without clear surface connection to larger bodies of water from protection, as well as “ephemeral” streams that only flow with rainfall or snowmelt, about 18 percent of the country’s total streams. The proposal is now undergoing 60 days of public comment.

In November, Iowa already allowed Iowa to halt enforcement of the rule until disagreement over it was settled in court. The most farmers seem to want that allowance made permanent by the Clean Water Rule rollback. The Iowa Farm Bureau shared a statement of support in December after the EPA announced the proposed rollback, and called the Obama Era rule an “overreach.”

As Iowa Sen. Joni Ernst told reporters, “Iowa’s farmers, ranchers, manufacturers and small businesses can now breathe a sigh of relief knowing that going forward a tire track that collects rain water won’t be regulated by the federal government.”

Iowa has serious water quality issues, however, caused for the most part by runoff from farm fields containing harmful nutrients like nitrate and phosphorus. The state recognizes the importance of on-farm streams and wetlands in managing soil and water quality, and encourages the construction of buffers between crops and waterways to minimize runoff into streams or wetlands.

Curt Zingula, a Linn County farmer who uses a saturated buffer on his farm to protect a creek, told the Sioux City Journal he is proactive about water quality management, but thinks the Clean Water Rule “cast a shadow” over a landowner’s entire farm.

Others believe the rule was necessary, however, and think the proposed rollback will worsen Iowa’s water problem. A staff editorial in the Gazette called Ernst’s statements “hyperbole” and pushed for more focus on the water itself in the discussions surrounding the proposed rule change.

“If the Trump administration can’t explain how its definition will lead to cleaner water, and all of its related benefits, it should go back to the drawing board,” it reads. “Otherwise, it’s simply replaced Obama’s ‘overreach’ with a dereliction of duty to protect the nation’s waters for future generations.”

University of Iowa drinking water exceeds maximum contaminant levels for disinfectant by-products

University of Iowa facilities management received notice on February 1 that its drinking water system contains levels of Total Trihalomethanes (TTHM) that exceed the federal drinking water standard.

In an email sent out to University faculty, staff and students on February 9, it was reported that the drinking water tested on average between 0.081 and 0.110 mg/L over the last year. The U.S. Environmental Protection Agency’s maximum contaminant level (MCL) for TTHM is 0.08 mg/L.

TTHM is a group of four chemicals: chloroform, bromodichloromethane, dibromochloromethane and bromoform. TTHM form when chlorine reacts with natural organic matter like leaves, algae and river weeds in drinking water. In its statement, the University said that more chlorination was necessary this year because higher than usual temperatures led to more organic waste in waterways.

The notice read, “You do not need to use an alternative (e.g., bottled) water supply. Disease prevention specialists with University of Iowa Hospitals and Clinics say special precautions are not necessary.”

Chloroform and dibromochloromethane are Class B carcinogens, meaning they have been shown to cause cancer in laboratory animals. TTHM has also been linked to heart, lung, kidney, liver, and central nervous system damage, according to a report by the University of West Virginia.

University officials cautioned, “However, some people who drink water-containing trihalomethanes in excess of the MCL over many years may experience problems with their liver, kidneys, or central nervous system, and may have an increased risk of getting cancer.”

A study by the California Department of Health suggests that even short-term exposure to high TTHM levels in drinking water can have serious consequences for pregnant women. Scientists monitored 5,144 women during their first trimester of pregnancy. Participants who drank five or more glasses of cold home tap water containing 0.075 mg/L or more of TTHM had a miscarriage rate of 15.9 percent. Women that drank less than five glasses per day or who had home tap water with less than 0.075 mg/L TTHM had a miscarriage rate of 9.5 percent.

A reverse osmosis filtration system for the University of Iowa drinking water supply is currently in its design phase. Facilities management expects to have the new system up and running within the next 18 months. Officials say it will help address Iowa’s nitrate problem and filter out naturally occurring organic matter, resulting in fewer TTHM.

Iowa could soon face water situation similar to Toledo

Algae blooms in Iowa could contaminate the water supply, similar to what recently happened in Toledo, and according to one expert, “it’s not a matter of if, it’s a matter of when.”

High levels of nitrogen and phosphorus inundate Iowa waterways and that coupled with high temperatures provides the perfect breeding ground for algae. The state has implemented a voluntary plan which encourages farmers to practice agricultural techniques that will lessen the amount of fertilizer run-off which leads to contaminated waterways in Iowa.

The U.S. Army Corps of Engineers recently advised beach-goers to avoid the waters at Lake Red Rock in Marion County due to excessively high levels of blue green algae which is known to contain toxins that are harmful to humans and can be lethal for animals. The Iowa Department of Natural Resources advises swimmers to take extra precaution in Iowa lakes during this time of the year. There are currently about dozen state-operated beaches in Iowa where swimming is not advised.

Attornys general from Iowa and 14 other agricultural and ranching states have spoken out against a recent U.S. Environmental Protection Agency proposed rule for the Clean Water Act, fearing the proposal would place excessive regulations on farmers and ranchers. EPA Administrator Gina McCarthy has defended the proposal and said it does not intend to place strict federal regulations on farmers.

Approximately 600 households in southwest Iowa were recently issued a boil order before consuming tap water after water quality tests concluded that chlorine levels were not sufficient. Chlorine is used to kill bacteria and other harmful toxins as part of the water filtration process but there was no indication that bacteria or other toxins had actually contaminated the water supply.

DNR looking for Iowans’ input on water quality

The Iowa Department of Natural Resources (DNR) has announced a series of public meetings to review the state’s water quality standards. The open discussions, which occur triennially in accordance with the federal Clean Water Act, will be held throughout Iowa in early September.

Iowans with ideas and opinions about state water quality goals are encouraged to attend one of the events. After the meetings, the department will review the public’s suggestions and adjust their work plan accordingly.

Rochelle Weiss, DNR water quality standards coordinator, describes the meetings as “the public’s opportunity to tell us what is important to them.”

Agricultural and environmental interests may be at odds

Earlier this week, Iowa Senator Chuck Grassley and several other members of the Senate Agriculture Committee met with U. S. Environmental Protection Agency Administrator Gina McCarthy. The aim of the closed-door meeting was to clarify several intersections between environmental regulations and agricultural practices.

However, the meeting failed to resolve tensions between the two interests. Grassley released a statement noting his discontent with the EPA’s efforts, stating that “the meeting did little to alleviate [his] concerns.”

Issues discussed in the meeting included methane emission regulations, the amount of ethanol in the federal Renewable Fuel Standard, and U. S. Supreme Court decisions on the 1972 Clean Water Act. EPA officials maintain that agricultural exemptions are still in place, while Republican senators claim that the Agency is overreaching.

Republican committee members had called for the meeting in a May 23 letter.

DNR Petitioned to Issue Hog Farm Water Permit

ANKENY, Iowa (AP) – An environmental advocacy group says it is delivering a petition with 5,000 names to the Iowa Environmental Protection Commission insisting the state crack down on water pollution that comes from large livestock farms.
Iowa Citizens for Community Improvement says it will demand at Tuesday’s commission meeting that the Iowa Department of Natural Resources issue a Clean Water Act operating permit to the Maschhoff Pork farm near Keosauqua in southeast Iowa.

The farm, with nearly 7,500 pigs, spilled thousands of gallons of manure into a creek on Nov. 4, just weeks after a DNR inspection. It has had several spills in recent years.

The state hasn’t issued a water permit to a hog facility before but environmental groups are increasingly pressuring the state to create rules to do so.
