About 23 million U.S. households depend on private wells as their primary drinking water source. These homeowners are entirely responsible for ensuring that the water from their wells is safe for human consumption.

Multiple studies show that, at best, half of private well owners are testing with any frequency, and very few households test once or more yearly, as public health officials recommend. Even in Iowa, which has some of the strongest state-level policies for protecting private well users, state funds for free private water quality testing regularly go unspent.

Is the water these households are drinking safe? There’s not much systematic evidence, but the risks may be large.

The U.S. Environmental Protection Agency still relies on a 15-year-old study showing that among 2,000 households, 1 in 5 households’ well water contained at least one contaminant at levels above the thresholds that public water systems must meet. While other researchers have studied this issue, most rely on limited data or data collected over decades to draw conclusions.

I’m an economist studying energy and agriculture issues. In a recent study, I worked with colleagues at Iowa State University, the University of Massachusetts Amherst and Cornell University to understand drinking water-related behaviors and perceptions of households that use private wells. We focused on rural Iowa, where runoff from agricultural production regularly contaminates public and private drinking water sources.

We found that few households followed public health guidance on testing their well water, but a simple intervention – sending them basic information about drinking water hazards and easy-to-use testing materials – increased testing rates. The burden of dealing with contamination, however, falls largely on individual households.

Nitrate risks

We focused on nitrate, one of the main well water pollutants in rural areas. Major sources include chemical fertilizers, animal waste and human sewage.

Drinking water that contains nitrate can harm human health. Using contaminated water to prepare infant formula can cause “blue baby syndrome,” a condition in which infants’ hands and lips turn bluish because nitrate interferes with oxygen transport in the babies’ blood. Severe cases can cause lethargy, seizures and even death. The EPA limits nitrate levels in public water systems to 10 milligrams per liter to prevent this effect.

Studies have also found that for people of all ages, drinking water with low nitrate concentrations over long periods of time is strongly associated with chronic health diseases, including colorectal cancer and thyroid disease, as well as neural tube defects in developing fetuses.

Nitrate pollution is pervasive across the continental U.S. Fortunately, it is relatively easy to determine whether water contains unsafe nitrate concentrations. Test strips, similar to those used in swimming pools, are cheap and readily available.

The water’s fine … or not

Mailing lists of households with private wells are hard to come by, so for our study we digitized over 22,000 addresses using maps from 14 Iowa counties. We targeted counties where public water systems had struggled to meet EPA safety standards for nitrate in drinking water, and where private wells that had been tested over the past 20 years showed nitrate concentrations at concerning levels.

We received responses from over half of the households we surveyed. Of those, just over 8,100 (37%) used private wells.

Although the Centers for Disease Control and Prevention recommends testing annually for nitrate, just 9% of these households had tested their water quality in the past year.

More concerning, 40% of this group used their wells for drinking water, had not tested it in the past year, and did not filter the water or use other sources such as bottled water. They were drinking straight from the tap without knowing whether their water was safe.

Our survey also showed that, despite living in high-risk areas, 77% of households classified their well water quality as “good” or “great.” This may be driven by a “not in my backyard” mentality. Households in our survey were more likely to agree with the statement that nitrate is a problem in the state of Iowa than to perceive nitrates as a problem in their local area.

Climate change is likely to worsen nitrate contamination in well water. In regions including the Great Lakes basin, increases in heavy rainfall are projected to carry rising amounts of nutrients from farmlands into waterways and groundwater. https://www.youtube.com/embed/yDaaIo3JBNw?wmode=transparent&start=0 Nitrate contamination is often thought of as a rural problem, but in California it also has shown up in urban areas.

Providing information and tools helps

To see whether education and access to testing materials could change views about well water, we sent a mailer containing a nitrate test strip, information about risks associated with nitrate in drinking water, and contact information for a free water quality testing program run by the state of Iowa to a random 50% of respondents from our first survey. We then resurveyed all households, whether or not they received the mailer.

Over 40% of households that received test strips reported that they had tested their water, compared with 24% of those that did not receive the mailer. The number of respondents who reported using Iowa’s free testing program also increased, from 10% to 13%, a small but statistically meaningful impact.

Less encouragingly, households that received the mailer were no more likely to report filtering or avoiding their water than those that did not receive the mailer.

Households bear the burden

Our results show that lack of information makes people less likely to test their well water for nitrate or other contaminants. At least for nitrate, helping households overcome this barrier is cheap. We asked respondents about their willingness to pay for the program and found that the average household was willing to pay as much as US$13 for a program that would cost the state roughly $5 to implement.

However, we could not determine whether our outreach decreased households’ exposure to contaminated drinking water. It’s also not clear whether people would be as willing to test their well water in states such as Wisconsin or Oregon, where testing would cost them up to a few hundred dollars.

As of 2024, just 24 states offered well water testing kits for at least one contaminant that were free or cost $100 or less. And while most states offer information about well water safety, some simply post a brochure online.

The upshot is that rural households are bearing the costs associated with unsafe well water, either through health care burdens or spending for treatment and testing. Policymakers have been slow to address the main source of this problem: nitrate pollution from agriculture.

In one exception, state agencies in southeastern Minnesota are providing free well water quality testing and offering a few households filtration systems in cases where their wells are laden with nitrate from local agricultural sources. However, this effort began only after environmental advocates petitioned the EPA.

If state and federal agencies tracked more systematically the costs to households of dealing with contaminated water, the scale of the burden would be clearer. Government agencies could use this information in cost-benefit assessments of conservation programs.

On a broader scale, I agree with experts who have called for rethinking agricultural policies that encourage expanding crops associated with high nutrient pollution, such as corn. More restoration of wetlands and prairies, which filter nutrients from surface water, could also help. Finally, while the Environmental Protection Agency can’t force well owners to test or treat their water, it could provide better support for households when pollutants turn up in their drinking water.

Across the United States, the second Monday of October is increasingly becoming known as Indigenous Peoples Day. In the push to rename Columbus Day, Christopher Columbus himself has become a metaphor for the evils of early colonial empires, and rightly so.

The Italian explorer who set out across the Atlantic in search of Asia was a notorious advocate for enslaving the Indigenous Taínos of the Caribbean. In the words of historian Andrés Reséndez, he “intended to turn the Caribbean into another Guinea,” the region of West Africa that had become a European slave-trading hub.

By 1506, however, Columbus was dead. Most of the genocidal acts of violence that defined the colonial period were carried out by many, many others. In the long shadow of Columbus, we sometimes lose sight of the ideas, laws and ordinary people who enabled colonial violence on a large scale.

As a historian of colonial Latin America, I often begin such discussions by pointing to a peculiar document drafted several years after Columbus’ death that would have greater repercussions for Indigenous peoples than Columbus himself: the Requerimiento, or “Requirement.”

Catch-22

In 1494, the Treaty of Tordesillas infamously divided much of the world beyond Europe into two halves: one for the Spanish crown, the other for the Portuguese. Spaniards lay claim to almost the entirety of the Americas, though they knew almost nothing about this vast domain or the people who lived there.

In order to inform Indigenous people that they had suddenly become vassals of Spain, King Ferdinand and his councilors instructed colonizers to read the Requerimiento aloud upon first contact with all Indigenous groups.

The document presented them with a choice that was no choice at all. They could either become Christians and submit to the authority of the Catholic Church and the king, or else:

“With the help of God, we shall powerfully enter into your country, and shall make war against you in all ways and manners that we can … we shall take you and your wives and your children and shall make slaves of them … the deaths and losses which shall accrue from this are your fault.”

It was a catch-22. According to the document, Indigenous people could either voluntarily surrender their sovereignty and become vassals or bring war upon themselves – and perhaps lose their sovereignty anyway, after much bloodshed. No matter what they chose, the Requerimiento supplied the legal pretext for forcibly incorporating sovereign Indigenous peoples into the Spanish domain.

At its core, the Requerimiento was a legal ritual, a performance of possession – and it was unique to early Spanish imperialism.

‘As absurd as it is stupid’

But for all of its seeming authority, the reading of the Requerimiento was an absurd exercise. It first occurred at what is now Santa Marta, Colombia, during the expedition led by Pedrarias Dávila in 1513. An eyewitness, the chronicler Gonzalo Fernández de Oviedo, stated the obvious: “we have no one here who can help [the Indigenous people] understand it.”

Even with a translator, though, the document – with its lofty references to the Biblical creation of the world and papal authority – would hardly be intelligible to people unfamiliar with the Spaniards’ religion. Explaining the convoluted document would require nothing less than a long recitation of Catholic history.

Oviedo suggested that to deliver such a lecture, you’d have to first capture and cage an Indigenous person. Even then, it would be impossible to verify whether the document had been fully understood.

However, for the Requerimiento’s greatest critic, Bartolomé de las Casas, translation was merely one of many problems. A missionary from Spain, Las Casas criticized the spurious requirement itself: that a people should be expected to immediately convert to a religion they have only just learned exists, and

“swear allegiance to a king they have never heard of nor clapped eyes on, and whose subjects and ambassadors prove to be cruel, pitiless and bloodthirsty tyrants. … Such a notion is as absurd as it is stupid and should be treated with the disrespect, scorn and contempt it so amply deserves.”

Las Casas, who documented abuses against Indigenous people in multiple books and speeches, was one of the most outspoken denouncers of Spanish cruelty in the Americas. While he believed Spaniards had a right and even an obligation to convert Indigenous people to Catholicism, he did not believe that conversion should be done under the threat of violence.

Wars and forced settlement

Indigenous people responded to the Requerimiento in numerous ways. When the Chontal Maya of Potonchan – a Maya capital now part of Mexico – heard the conquistador Hernando Cortés read the document three consecutive times, they answered with arrows. After Cortés captured the town, they agreed to become Christian vassals of Spain on the condition that the Spaniards “leave their land.” When Cortés’ men remained after three days, the Chontal Maya attacked again.

Farther north, Spanish expeditioners Alvar Núñez Cabeza de Vaca and Melchior Díaz used the Requerimiento to forcibly relocate various Indigenous groups.

A bloodthirsty governor of the province, Nuño Beltrán de Guzmán – so violent that the Spanish themselves imprisoned him for abuses of power – had driven Indigenous residents out of the Valley of Culiacan in a series of brutal wars. But in 1536, Cabeza de Vaca and Díaz forced several groups, including the Tahue, to repopulate the valley after convincing them to accept the terms of the Requerimiento.

Resettlement would enable the collection of tribute and conversion to Catholicism. It was simply easier to assign missionaries and tribute collectors to established Hispanic townships than to mobile communities spread out across vast territories.

Cabeza de Vaca encouraged Indigenous leaders to accept the proposition by claiming that their god, Aguar, was the same as the Christians’, and so they should “serve him as we commanded.” In such cases, conversion to Catholicism was just as farcical as the Requerimiento itself.

Violence and colonial legacy

Even when Indigenous people accepted the Requerimiento, however, Las Casas wrote that “they are (still) harshly treated as common slaves, put to hard labor and subjected to all manner of abuse and to agonizing torments that ensure a slower and more painful death than would summary execution.” In most cases, the Requerimiento was simply a precursor to violence.

Dávila, the conquistador of present-day northern Colombia, once read it out of earshot of a village just before launching a surprise attack. Others read the Requerimiento “to trees and empty huts” before drawing their swords. The path to vassalage was paved in blood.

These are the truest indications of what the Requerimiento became on the ground. Soldiers and officials were content to violently deploy or discard royal prerogatives as they pleased in their pursuit of the spoils of war.

And yet, despite the viciousness, many Indigenous peoples survived by stringing their bows like the Chontal Maya, or negotiating a new relationship with Spain like the Tahue of Culiacan. Tactics varied greatly and changed over time.

Many Indigenous nations that exercised them survive today, long outliving the Spanish Empire – and the people who carried the Requerimiento on their crusade across the Americas.
