SEYMOUR — By the time Bradley Burmeister met his high school science teacher more than a decade ago, concerns had already surfaced about an ancient poison that was appearing in drinking water around their Fox River Valley community. Burmeister never suspected, though, that his family\u2019s well would provide some of the scariest data.<\/p>\n

High levels of arsenic, a substance used as a poison since the Middle Ages, had been detected in 1989 in several counties in the Fox Valley region of northeastern Wisconsin. In 2003, Seymour High School science teacher Dennis Rohr and his students began a study of private well water samples from the area that would continue for the next five years.<\/p>\n

The arsenic level the students detected in the Burmeister family\u2019s well was off the charts: 1,650 parts per billion (ppb), or 165 times the federal health standard of 10 ppb. Burmeister \u2014 whose experience in the study sparked an interest in science that culminated in medical school \u2014 recalls it being the highest level found in the study.<\/p>\n

\u201cMy parents weren\u2019t too surprised, they just said, \u2018That\u2019s probably our luck,\u2019 \u201d Burmeister said. \u201cWe started drinking bottled water all the time and also used that for cooking.\u201d<\/p>\n

To this day, Burmeister\u2019s parents regularly buy a case of gallon-sized water jugs at the grocery store. Despite the inconvenience, Burmeister said his parents feel it is a more affordable way to address their arsenic problem than drilling a new well or purchasing a water treatment system.<\/p>\n

The Burmeisters are not the only family having to find alternatives to turning on the tap; arsenic is a major concern in Outagamie and Winnebago counties. The Wisconsin Department of Natural Resources designated an arsenic advisory area in these counties in 1993 and implemented stricter regulations for testing and well construction in 2004 and 2014.<\/p>\n

But arsenic problems are not confined to northeastern Wisconsin. Levels above the federal standard have been detected in 51 of Wisconsin\u2019s 72 counties, according to a 2006 Wisconsin Groundwater Coordinating Council report.<\/p>\n

The most serious health effects from arsenic exposure include a variety of cancers, nerve damage, diabetes and cardiovascular disease. Chronic low-level exposure during childhood has also been linked to decreased intelligence.<\/p>\n

In a 2014 study, researchers studying schoolchildren in Maine found regular consumption of drinking water containing 5 ppb of arsenic or more was associated with a significant IQ reduction in students in grades three to five.<\/p>\n

“The magnitude of the association \u2026 raises the possibility that levels (of arsenic in drinking water) that are not uncommon in the United States pose a threat to child development,\u201d the researchers found.<\/p>\n

A 2015 study of infants led by Dartmouth University researchers found that arsenic in a mother\u2019s urine, likely due to her consumption of contaminated well water during pregnancy, \u201cwas associated with a higher risk of infection during (an infant\u2019s) first year of life \u2026 and with diarrhea and respiratory symptoms.\u201d<\/p>\n

Human activity can mobilize arsenic<\/strong><\/p>\n

In 2001, the U.S. Environmental Protection Agency lowered the federal health standard, or maximum contaminant level, for arsenic in public drinking water from 50 to 10 ppb. This step reflected the increasing scientific evidence for the dangers of arsenic exposure to human health and matched the World Health Organization\u2019s global drinking water standard.<\/p>\n

The highest level ever detected in the state was found in a private well in northeastern Wisconsin. The well tested at 15,000 ppb \u2014 1,500 times the new federal threshold.<\/p>\n

\u201cWe have an arsenic hot spot in Wisconsin,\u201d said John Luczaj, a geoscience associate professor at the University of Wisconsin-Green Bay.<\/p>\n

Madeline Gotkowitz, a hydrogeologist at the Wisconsin Geological and Natural History Survey, agreed. \u201cArsenic is a big problem in Wisconsin, and I don\u2019t think many realize that,\u201d she said.<\/p>\n

The dangerous chemical can end up in groundwater through multiple mechanisms. In Wisconsin, arsenic is typically released when naturally occurring sulfide minerals in certain types of bedrock aquifers break down by coming into contact with oxygen.<\/p>\n

In 1987, the DNR discovered that the St. Peter Sandstone aquifer in northeastern Wisconsin contains a high concentration of these sulfide minerals. Knowing that it was the water source of more than 20,000 private wells, agency officials knew this might spell trouble.<\/p>\n

\u201cSeymour High School rests directly above the St. Peter Sandstone formation,\u201d science teacher Rohr said. \u201cSo arsenic was the main focus (of our water study) as it impacted our local community the most.\u201d<\/p>\n

The oxygen that sets off the breakdown of sulfide minerals can be introduced by well drilling and disinfection methods, or when the water table \u2014 the level below which the ground is saturated with water \u2014 is drawn down. This may occur during periods of drought, or be triggered by human use, such as the operation of high-capacity wells.<\/p>\n

Because of this interplay between geology and human activity, Luczaj said, private wells whose water previously tested fine for arsenic may lose their integrity.<\/p>\n

Patrick Laughrin is all too familiar with the effect of high-capacity wells in his part of the state. He lives in Hilbert in Calumet County, just east of Winnebago County.<\/p>\n

\u201cThe arsenic in our well showed up for the first time when the high-capacity wells came in and dropped the water table,\u201d Laughrin said. \u201cIt makes sense. If you drop the water table, you get more oxygen and that releases more arsenic into your water.\u201d<\/p>\n

State steps up regulation<\/strong><\/p>\n

In 2004, the DNR introduced tougher arsenic laws in Winnebago and Outagamie counties. With 20 percent of the private well samples there analyzed in 1992-93 exceeding the EPA\u2019s new health standard of 10 ppb, this area was thought to pose the greatest exposure threat to the largest number of residents. The new regulation required all drilling and disinfection methods to minimize the exposure of sulfide rocks to oxygen.<\/p>\n

For Luczaj, this was a step in the right direction, but he said it may not go far enough.<\/p>\n

\u201cThe geology doesn\u2019t stop at political boundaries,\u201d Luczaj said. \u201cThe area definitely extends into the neighboring counties. It\u2019s pretty likely that we\u2019ll see increasing problems as aquifers get drawn down.\u201d<\/p>\n

A 2013 study of 3,868 private wells from across the state found 2.4 percent of them exceeded arsenic levels of 10 ppb. If that proportion was applied to all of the estimated 940,000 households on private wells in Wisconsin \u2014 a calculation endorsed by the study\u2019s lead author \u2014 residents of 22,560 homes may be consuming unsafe levels of the chemical.<\/p>\n

Testing, grants rarely used<\/strong><\/p>\n

The DNR has a well compensation grant program that makes residents whose well water exceeds 50 ppb of arsenic \u2014 five times the federal standard \u2014 eligible for up to $9,000 to drill a new well. The program can be used to address other types of contamination as well.<\/p>\n

However, during the past five years, only 10 or fewer grants were awarded per year. Households whose water contains up to 49 ppb \u2014 almost 10 times the amount of arsenic shown to impact a child\u2019s intellectual development \u2014 have to cover the cost of a new well on their own, or pay for other options that will make their water safe to drink.<\/p>\n

To reduce arsenic exposure, people must be aware of its presence in their drinking water in the first place. But with a mere 16 percent of private well owners in Wisconsin estimated to test their water annually, the number of residents who are unaware is large.<\/p>\n

Raising that awareness was part of Rohr\u2019s goals when he began his water study in 2003. In 2014 \u2014 11 years after Rohr\u2019s study \u2014 the DNR revised its arsenic regulation yet again, recognizing the persistent nature of Wisconsin\u2019s arsenic problem.<\/p>\n

This time, the new state law required that arsenic, in addition to coliform bacteria and nitrate, be tested at the time of a property transfer, but only if the buyer requests a well inspection. The same three contaminants also have to be tested after the completion of certain well repair work, such as fixing a broken water pump.<\/p>\n

Laughrin said the new law helps address one of his long-held concerns with people only testing their water for bacteria and nitrate: when those results are within safe ranges, they assume everything else is fine as well. And yet their water may be contaminated with arsenic or other substances for which the water has never been tested.<\/p>\n

Given the potential for negative health effects from regular consumption of unsafe drinking water, Laughrin suggested another group of stakeholders who could play a large role in raising people\u2019s awareness: family physicians.<\/p>\n

\u201cWhen my wife and I went to our doctor\u2019s office four or five years ago, they did not even ask if we had a private or municipal well,\u201d he said. \u201cThey\u2019re starting to do it more often now. But there\u2019s a lot to go on this yet.\u201d<\/p>\n

Bad wells replaced by city water<\/strong><\/p>\n

Some communities in Wisconsin have addressed their arsenic problem by offering citizens a switch from private to municipal water. The Stilson family in Oshkosh took advantage of this opportunity in 2000, following several years of having bottled water delivered to their home after the level of arsenic in their well rose to 999 ppb, or nearly 100 times the health standard.<\/p>\n

\u201cWe said, \u2018Let\u2019s just get city water and get it over with,\u2019 \u201d Lynn Stilson said. \u201cSome people kept their well so they could use the water for their lawn, but ours was capped, we just got it all done at once. I think at this point everybody here has city water.\u201d<\/p>\n

In 2013, the city of Algoma water utility in Kewaunee County offered discounted arsenic testing to private well owners to gauge their interest in connecting additional homes to public water.<\/p>\n

They found that 9 percent of the 330 homeowners who participated had levels above 10 ppb, with a maximum of 1,000 ppb. In 2014, the utility built water main extensions in neighborhoods with at least 70 percent of residents indicating an interest in switching to municipal water.<\/p>\n

City water is required by law to be tested regularly for arsenic, which takes the burden of monitoring water quality off the homeowners\u2019 shoulders. And public wells have another advantage over private wells: they tend to be drilled deeper.<\/p>\n

\u201cThe private wells are generally shallower and more likely to draw water from near the water table,\u201d Luczaj said. \u201cIn general, municipal wells are also constructed at higher quality than private wells.\u201d<\/p>\n

Wisconsin\u2019s public water systems have only rarely exceeded the federal arsenic standard, although municipal well operators in some places, including the village of Suring in Oconto County, continue to struggle with arsenic problems that first emerged six years ago.<\/p>\n

When drilling a new well is too expensive, a switch to city water not possible, or purchasing bottled water too big a hassle, another remediation option is to install an in-home water treatment system. The most cost-effective method is called a reverse osmosis system, which removes 95 percent of arsenic, as well as other contaminants.<\/p>\n

Luczaj said vigilance is the key to avoiding arsenic, since human activity can increase the amount of the naturally occurring contaminant in well water. \u201cA one-time test for arsenic is not at all sufficient,\u201dhe said.<\/p>\n

Added Kevin Masarik, groundwater education specialist at the UW-Stevens Point: \u201cA lot of people only test their water because they perceive a problem based on a color or odor issue. But they are largely ignorant of important tests to consider (for contaminants) that they may not be able to taste, see or smell.\u201d<\/p>\n
