During an Easter celebration in 2014, Jacob Reeves’ body started swelling up. Then he developed an unusual rash. After multiple hospital visits, Jacob, now 11, was diagnosed with juvenile dermatomyositis.
It is a rare inflammatory disease that affects muscles, skin and blood vessels, afflicting just 3 out of every 1 million children each year, according to the American College of Rheumatology.
The cause of the disease is unknown, so Dawn Reeves went looking for answers as to why the second-youngest of their five children suddenly fell ill. She and her husband, Doug, started with the well at their home about 20 miles southeast of Madison.
Testing found the family’s water was contaminated with fertilizers and pesticides. Most surprising was the weed killer atrazine, which has been banned from the area where the Reeves family lives for 20 years. It was found at twice the state and federal drinking water health standard.
Follow-up testing by the state Department of Agriculture, Trade and Consumer Protection found 8.2 parts per billion of atrazine — nearly triple the state health standard — present in the water they drank every day.
In a letter, DATCP warned that “Long-term exposure to atrazine may cause a variety of health problems, including weight loss, heart damage and muscle spasms.”
When it comes to pesticides — including insecticides, herbicides and fungicides — in our water, the Wisconsin Center for Investigative Journalism has found:
One-third of private drinking water wells in Wisconsin had pesticide contamination, according to the most recent comprehensive statewide survey;
Nearly two-thirds of the more than 90 pesticides used on Wisconsin crops lack a health standard for water;
Wisconsin’s atrazine rules, which are described as the strictest in the country, have significantly cut use of the herbicide and led to a sharp decline in the number of wells tainted with atrazine;
But atrazine restrictions in Wisconsin have been replaced by increased use of other herbicides, whose effects on humans are still not well understood;
The federal government’s proposal to further restrict atrazine is facing pushback from agricultural groups in Wisconsin and the state’s Republican U.S. Senator, Ron Johnson.
Atrazine has been one of the most widely used herbicides in the United States for decades, according to the U.S. Department of Agriculture. The pesticide manufacturer Syngenta advertises the weed killer as “safe for people, good for the environment and the economy.”
But atrazine is considered an endocrine disruptor and has been tied to abnormal sexual development in animals. The endocrine system regulates blood sugar, reproductive systems, metabolism and development of the brain and nervous systems.
Testing of the Reeves’ well also detected dangerous levels of nitrate, which comes from nitrogen-based fertilizers, and low levels of the pesticide alachlor.
The results convinced Dawn Reeves that Jacob’s sudden illness was caused by the water.
“It wasn’t a (three-in-one-million) rare disease, it was atrazine poisoning to the extreme,” Dawn Reeves said of Jacob’s sudden illness. “It blew (the doctors) away and all of their statistics out of the water.”
Although there is no direct evidence that supports her theory, the exact health effects of long-term consumption of water containing pesticides are “not completely understood,” according to the state Department of Natural Resources.
The agency says, however, that exposure could increase susceptibility to “certain diseases, including cancer.”
The U.S. Environmental Protection Agency is considering further restrictions on atrazine but has gotten strong opposition from agricultural groups, including some in Wisconsin. A recent EPA draft risk assessment found that atrazine is dangerous to a variety of plants and animals both on land and in water.
Sen. Johnson, R-Oshkosh, has called on the agency to explain the rationale for the proposed rules, which he said would impose “harmful restrictions on Wisconsin farmers.”
One-third of wells contaminated
The Reeves family is among the roughly 940,000 Wisconsin households that rely on private wells for their water. There is no testing requirement for private well owners, which means “everybody’s on their own” when it comes to water quality, said Stan Senger, DATCP’s environmental quality section chief.
By contrast, public water supplies are tested for 36 contaminants found in pesticides, including atrazine and alachlor. The EPA sets these standards, and monitoring is enforced by the state DNR.
In 2007, the last time DATCP released a comprehensive survey of pesticides in groundwater, the results were disturbing. Of 398 private wells, 33.5 percent had detectable levels of a pesticide or a pesticide metabolite, which is formed when the active ingredient or “parent” chemical breaks down as it penetrates soil.
At the time, the agency tested for 32 active ingredients. DATCP is now updating the study and testing for 98 ingredients, Senger said.
Wisconsin regulators have long known the dangers of atrazine. In 1991, the state put in place a rule that allowed DATCP to set maximum application rates and prohibit atrazine use outright in certain areas. There are currently 101 prohibition areas in the state covering 1.1 million acres. The last was added in 2011.
DATCP spokeswoman Donna Gilson said the most recent round of testing has detected some “very localized groundwater problems.”
Rather than create new atrazine-prohibition areas, which can take two years, Gilson said the agency has instead reached voluntary agreements with individual farmers near Spring Green and Reedsburg who agreed to stop using atrazine or simazine, a pesticide that share metabolites with atrazine.
Citing harmful effects to animals, EPA’s draft risk assessment proposes new restrictions that agricultural interests including the Wisconsin Corn Growers Association say would “effectively ban” use of the chemical in about 100 herbicide mixes.
The agency is recommending a maximum of 3.4 parts per billion of atrazine in surface water to protect plant and animal life, compared to the current level of concern of 10 ppb; opponents cite research that has found 25 ppb and higher to be safe. The Senate governmental affairs committee, which Johnson chairs, is examining the effects that the proposed EPA rules could have on farmers.
At a committee hearing Aug. 17, Jim Zimmerman, a Rosendale farmer and National Corn Growers Association board member, testified, “Without atrazine, farmers would have to use higher quantities of other herbicides that are less effective.” He also predicted that lowering the threshold would increase tillage, which disturbs the land, “threatening soil health and nutrients.”
Other countries have gone even further. Germany and Italy prohibited use of the chemical 25 years ago. The European Union banned it in full in 2004 — even in Switzerland, where Syngenta, the major producer of atrazine, is based.
Researcher: Regulation works
Joanna Ory was a USDA National Institute of Food and Agriculture pre-doctoral fellow at the University of California-Santa Cruz who studied Wisconsin’s approach to atrazine. She found that use of the herbicide has plummeted in Wisconsin, as has contamination of wells by atrazine.
“The rules that Wisconsin put into place — to create the prohibition areas as well as having the application rate limits — are pretty progressive and are the strictest of any state in the country,” Ory said.
When comparing 3,719 samples from 610 wells, Ory found contamination decreased steadily, from an average of 3 ppb in 1992 to 0.67 ppb in 2013. She concluded that “the atrazine rule in Wisconsin is a policy that has contributed towards strong improvements in water quality protection.”
But the rule may not have been enough to protect the Reeves family. They live in the middle of a prohibition zone covering most of Dane County.
The 298-page DATCP investigation obtained under the state’s open records law by the Wisconsin Center for Investigative Journalism found no evidence of nearby farmers using atrazine, which has been banned in the area since 1995, and no neighboring wells testing positive for atrazine.
Officials were never able to find the source and closed the case.
“Could we have missed the point source?” Senger asked. “Certainly, it’s not a perfect process, and you can’t go out and poke a bunch of holes all over people’s properties. But we certainly did not find a smoking gun for use in the area or for spills or anything like that.”
Dawn Reeves said the good news is that the family has installed filters that take out the contaminants.
Atrazine falls, other herbicides rise
But Ory’s research has found that, in Wisconsin, decreased atrazine use has been accompanied by a large increase in use of other herbicides on corn fields, including glyphosate, whose health effects are unclear.
Ory said there may be negative synergistic effects if groundwater contains a “chemical soup” of pesticides. Wisconsin’s current groundwater law does not set a standard for total pesticides in water, nor is there a standard set nationally by the EPA. The European Union’s standard is 0.5 ppb.
As for the Reeves family, the dissolved organic carbon and reverse osmosis filtration systems they installed gave them some peace of mind. But it came at a high price.
Jacob’s treatment — a regimen of “wicked drugs” that Reeves described as fighting poison with poison — finally ended in August. She estimates the filters cost more than $3,000; plus a family friend paid for six months of bottled water. Reeves said she even threw out most of the food she canned from her garden.
Reeves said she is angry that all of the steps she and Doug took to protect their children may have been undermined by contaminated water.
“For us, we grew our own food,” she said. “We kept them at home and home schooled them. We did it all on purpose to try to keep our kids healthy. And then only to find out that despite everything we were trying to do to try to keep them healthier, that some poison in our water turned it all upside down.”
