Millions of people across the US use well water, but very few test it often enough to make sure it’s safe
Gabriel Lade, Macalester College
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.

Dozens of cyclists and pedestrians are killed each year in Philly − an injury epidemiologist explains how to better protect bike lanes, slow drivers down and reduce collisions
D. Alex Quistberg, Drexel University
Over 60 pedestrians and cyclists have been killed each year in Philadelphia in recent years.
Compared with other big cities, Philadelphia’s death rate for both pedestrians and cyclists is higher than New York and Chicago but lower than Los Angeles and Houston.
Across the U.S., more pedestrians and bicyclists are killed or seriously injured today than any time over the past 40 years. Over 7,500 pedestrians and over 1,100 bicyclists died in traffic collisions in 2022, the most recent year with available data, according to the National Highway Traffic Safety Administration.
As an injury epidemiologist in Philadelphia who studies pedestrian and bicyclist injuries in the U.S. and Latin America, I want to share several evidence-based ways that Philadelphia can make walking, biking and getting around the city safer for everyone.
Protect bike lanes
Protected bike lanes have physical barriers that prevent drivers from entering the bike lane to park or pass other drivers.
They are particularly useful on high-volume cycling corridors and offer cyclists much more protection than lanes that are merely painted but have no physical barriers or lanes with flexible posts that can be driven over.
Flexible posts, for example, were unable to block the collision that killed Barbara Friedes, chief pediatric resident at Children’s Hospital of Philadelphia, in Center City in July 2024 when a drunk driver sped through the bike lane where Friedes was bicycling.
Research suggests protected bike lanes can improve safety for pedestrians and drivers too. This is likely because they tend to cause drivers to slow down.
The Bicycle Coalition of Greater Philadelphia and other local bike safety advocacy groups have called for the city to replace unprotected lanes with protected lanes and also add protected bike lanes to more roadways that currently don’t have any.
In October 2024, the city announced it will install concrete barriers to protect the bike lanes on Spruce and Pine streets in Center City, including where Friedes was killed. That same month, the City Council unanimously passed a “Get Out the Bike Lane” bill that increases the fines for drivers who stop or park in a bike lane.
Slow drivers down
Traffic-calming measures are engineering and road design strategies that slow vehicles down, make pedestrians more visible to motorists and provide safer crossing areas.
They include speed humps, curb extensions and protected intersections, as well as 20 mph speed zones.
Automated speed enforcement, which involves cameras that capture the license plates of drivers who are speeding, has led to major reductions in speeding and serious collisions on Roosevelt Boulevard. The street, which runs through North and northeast Philadelphia, has been named one of most dangerous roads in the country in various analyses by news and transportation organizations. Due to this success, the city plans to expand automated speed enforcement to Broad Street in 2025 and potentially other locations in the future.
Traffic-calming measures can benefit all road users by reducing traffic congestion so drivers and public transit riders face fewer delays. They can also boost nearby businesses by increasing foot traffic and making business corridors more pleasant for shoppers.
Encourage fewer cars on the road
Philadelphia can adopt more policies that promote walking or biking over driving. These include open streets or ciclovías, where streets are closed down to motor vehicle traffic and opened to cyclists and pedestrians. Philadelphia occasionally does this on stretches of 18th Street and Walnut Street in Center City.
Increasing parking fees can also reduce traffic congestion. Parking fees generally do not reflect the true cost of driving in cities, which includes maintaining parking spaces and infrastructure. The low cost of parking is essentially a subsidy to drivers. While there are fears that reduced parking hurts business owners, substantial evidence indicates businesses benefit from increased foot and bicycle traffic.
The city could also reduce the number of parking spaces and implement congestion pricing, which involves charging fees to drive in certain areas of a city to reduce traffic congestion.
This may be a challenge, considering the recent experience of New York City, which spent decades preparing for congestion pricing only to have it blocked by the governor, though it seems it now has a chance of being implemented. How much success New York has with congestion pricing will likely determine the feasibility in Philadelphia and other U.S. cities.
Improve public transportation
Expanding public transportation and lowering or eliminating fares can also help protect pedestrians and cyclists by reducing car use. I believe these measures could help ensure the other policies mentioned above are effective.
However, Philadelphia’s public transportation is currently in a critical state. Facing funding shortfalls due to years of declining ridership, the Southeastern Pennsylvania Transportation Authority has proposed service cuts and significant fare increases beginning Jan. 1, 2025. Gov. Josh Shapiro has spared the system from these cuts for now by flexing federal highway funds, but long-term solutions are needed to ensure the survival and revival of public transportation in Philadelphia.
Addressing gun violence, drug use and other crimes may also make public transportation in Philadelphia safer and more attractive. While violent crimes on Philadelphia’s public transportation have dropped dramatically in 2024, four people have lost their lives on SEPTA vehicles so far this year.
Collect better data
Considering the increase in road traffic deaths in Philly since the start of the COVID-19 pandemic, substantial efforts are needed to reach the city’s Vision Zero goal of reducing road traffic deaths to zero by 2030.
In my view, this includes better data on transportation use and which interventions and policies are working and which are not.
Road safety surveillance could be improved in Philadelphia and across Pennsylvania by linking crash records to other data, such as hospital and clinical data of crash victims, as well as insurance costs to better understand the burden of road traffic injuries on the city and the state.
Data is also key to ensuring public policies are implemented equitably. The Vision Zero plan includes a focus on lower-income neighborhoods and those with higher proportions of racial and ethnic minorities. Those areas have three times as many serious injuries and deaths as other neighborhoods, and road traffic injury and deaths rates are 30% higher among people of color compared with white residents.
