Allison Roderick has a warning and a pledge for rural residents of her county: The water from their wells could be contaminated, but the government can help make it safe.

Roderick is the environmental health officer for Webster County in north-central Iowa, where a few thousand rural residents live among sprawling corn and soybean fields. Many draw their water from private wells, which are exempt from most federal testing and purity regulations. Roderick spreads the word that they aren't exempt from danger.

More than 43 million Americans rely on private wells, which are subject to a patchwork of state and local regulations, including standards for new construction. But in most cases, residents are free to use outdated wells without having them tested or inspected. The practice is common despite concern about runoff from farms and industrial sites, plus cancer-causing minerals that can taint groundwater.

"You're cooking with it. You're cleaning with it. You're bathing in it - and, nowadays, there are so many things that can make you sick," Roderick said.

Federal experts estimate more than a fifth of private wells have concentrations of contaminants above levels considered safe.

Like many states, Iowa offers aid to homeowners who use well water. The state provides about $50,000 a year to each of its 99 counties to cover testing and help finance well repairs or treatment. The money comes from fees paid on agricultural chemical purchases, but about half goes unused every year, according to the Iowa Department of Natural Resources.

Roderick, who started her job in 2022, aims to spend every penny allotted to her county. Last spring, she snared an extra $40,000 that other counties hadn't used. She promotes the program online and by mailing piles of postcards. Traveling the countryside in a hand-me-down SUV from the sheriff's department, she collects water samples from outdoor spigots and sends them to a lab.

When she finds contamination, she can offer up to $1,000 of state grant money to help with repairs, or up to $500 to cap an abandoned well.

Experts urge all users of private wells to have them tested at least annually. Even if wells meet modern construction standards and have tested clean in the past, they can become contaminated as the water table rises or falls and conditions change above them. A faulty septic system or overapplication of fertilizer or pesticide can quickly taint groundwater.

Too many residents assume everything is fine "as long as the water is coming out of the tap and it doesn't smell funny," said Sydney Evans, a senior science analyst for the Environmental Working Group, a national advocacy organization that studies water pollution.

The main concerns vary, depending on an area's geology and industries.

In Midwestern farming regions, for example, primary contaminants include bacteria and nitrates, which can be present in agricultural runoff. In rural Nevada and Maine, arsenic and uranium often taint water. And, throughout the country, concerns are rising about the health effects of PFAS chemicals, widely used products also known as "forever chemicals." A recent federal study estimated at least 45% of U.S. tap water contains them.

Filters can help ensure safety, but only if they're selected to address the specific problem affecting a home's water supply, Evans said. The wrong filter can give a false sense of safety.

Evans said people who wonder about possible contaminants in their area can ask to see test results from wells supplying nearby community water systems. Those systems are required to test their water regularly, and the results should be public, she said: "It's a great place to start, and it's free and easy."

She also said people who rely on private water wells should ask local health officials about eligibility for help paying for testing and possible repairs or filters. Subsidies are often available but not publicized, she said.

A study by Emory University researchers published in 2019 found that all states have standards for new well construction, and most states require permits for them. However, the researchers wrote, "even in states with standards for water quality testing, testing is typically infrequent or not conducted at all."

Some longtime rural residents live in homes that have been in their families for generations. They often know little about their water source. "They'll say, 'This is the well my grandfather dug. We've used it ever since, and no one's had an issue,'" said David Cwiertny, director of the University of Iowa's Center for Health Effects of Environmental Contamination. They might not realize impure water can harm health over time, he said.

Some states require inspection and tests of private wells when properties are sold. Iowa doesn't mandate such measures, although Webster County does. It's a good idea for homebuyers anywhere to request them, said Erik Day, who oversees the private well program for the Iowa Department of Natural Resources. He also recommends asking for a technician who can run a flexible scope down the well to visually inspect the inside.

Day estimated fewer than 10% of Iowa's private well owners have them tested annually, even though testing can be free under the state grant program.

In Webster County, Larry Jones recently took advantage of free well testing at a weathered ranch house he bought west of Fort Dodge, in a subdivision bordering a large soybean field. Jones lives next door to the 54-year-old home, and he is refurbishing it as a place for his relatives to stay.

Roderick, the county health official, sampled water from the well and found it was tainted with bacteria. She offered Jones $1,000 from the state grant to help get it fixed. He added a few thousand dollars of his own and hired a contractor.

"It's an investment for the future," he said. "You're talking about your family."

The old well was made with a 2-foot-diameter concrete casing sunk vertically in sections about 60 feet into the ground. A smaller plastic pipe ran down the middle of the casing to water at the bottom. A pump pulled water up through the smaller pipe and into the home.

Lynn Rosenquist, who owns a local well-repair business, told Jones the well probably was original to the house and likely met standards when it was built. But at least one chunk of concrete had broken off and fallen in.

Repairs took two days of heavy work by Rosenquist and his brother, Lanny, who are the third generation of their family to maintain wells. The brothers used a backhoe and small crane to remove much of the concrete casing. They replaced it with a narrower, PVC pipe, which they sealed with a cement mixture to prevent seepage from the surface. When finished, they "shocked" the system with a bleach solution, then flushed and tested again.

Such modern construction is less prone to becoming tainted, Roderick said. "If it's not sealed airtight, bacteria can get in there and it's just gross," she said.

Grossness is not the only thing Roderick considers. Besides E. coli and other bacteria, she tests for nitrates and sulfates, which can exist in farm or lawn runoff or come from natural sources, and for arsenic and manganese, which can occur in rock formations. She plans to add tests for PFAS chemicals soon.

She collects the water in small plastic bottles, which she mails to a lab. She enters information about each well into a state database. If the tests turn up contaminants, she advises homeowners of their options.

Roderick said she enjoys the routine. "I've met so many people - and I've met a lot of dogs," she said with a laugh. "I love the feeling that I'm really helping people."

Work is being done in rural areas across Texas to make sure students are prepared for the workforce even if they intend to stay put after graduation.

One new study showed only 31% of adults in non-metro areas have a degree from a junior college or university. The nonprofit Jobs for the Future creates opportunities for the education system and local businesses to work together in hopes of increasing the number.

Sarah Jenness, senior manager of the group, said there are three key changes leaders in rural areas could make to improve training for students.

"Strategy number one, build on your local strengths and contacts," Jenness outlined. "Strategy number two is thinking about how to prioritize inclusive economic development. And then finally, the third strategy was around embedding remote opportunities."

Jenness argued schools, local economic development agencies and businesses need to collaborate to create opportunities. A couple of options are dual enrollment, where high school students also earn college credits, and work-based learning, so they can hone their skills on the job.

The study found in the U.S., the benefits of economic systems are unevenly distributed and certain groups and communities suffer the most, particularly rural areas. Disparities are also seen across lines of race, ethnicity and gender.

Jenness stressed gaps can be closed if rural students receive training for the types of jobs available in their communities.

"What are the industries that employ the most rural workers? And the top three that we think tend to be -- you know, have good quality jobs -- are industries like government, manufacturing and health care," Jenness explained.

She added remote work is also a key strategy to ensure rural students have access to a variety of well-paid jobs.

A lack of staff and know-how often means rural towns miss out on grants to improve their communities, and a Texas group is trying to balance the scales.

Billions of dollars will soon be flowing from the federal government to states for broadband, water and energy upgrades, transportation infrastructure and other projects. To help rural towns and nonprofits secure the money, Texas Rural Funders has stepped in.

Kelty Garbee, executive director of the group, said their online grants hub includes a list of grants available to rural groups.

"I regularly receive calls saying, 'We need to upgrade our fire station or our school is looking for support for a particular project,'" Garbee explained. "It's very overwhelming to figure out where to find grants in the first place."

Garbee noted about 50 federal and state grant opportunities are listed on the website, along with grant writers who can be hired to assist rural governments or organizations with applications. She explained the Hub preselects grants for which they know rural areas are eligible.

She pointed out essential needs in small towns to often go unfunded because of limited tax revenues. She hopes resources on the hub's website will give small communities a leg up.

"Often in a rural community, one person has so many jobs," Garbee observed. "What we've done is vet the grant writers. They'll send in work samples of grants they've written so you can actually download this roster of grant writers."

Texas is expected to receive about $2.5 billion for water infrastructure through the Infrastructure Investment and Jobs Act. As the state with the largest rural population, it also will receive billions in federal dollars in broadband infrastructure grants.

The Rural Advancement Foundation International is taking action against food injustices impacting farmers of color and rural communities through its Farm and Faith Partnerships Project.

In North Carolina, about 1.2 million people face food insecurity, and 394,000 of them are children.

Jarred White, Farm and Faith Partnerships project manager, said the Farm and Faith Project sprouted during the pandemic, responding to challenges of food insecurity and racial land loss.

"We hope that these relationships result in farmers of color gaining additional sources of income and increased access to new local markets," he said, "and rural faith community members and other community members gaining increased food security and access to fresh healthy foods."

Through partnerships with local faith communities and organizations such as The Duke Endowment, he said, congregations are forming local food-box purchasing groups or hosting farmers' markets in their parking lots. He said this type of work helps farmers of color who grapple with systemic racism in the food system.

Black farmers own less than 1% of the nation's farmland compared with about 95% of farmland owned by their white counterparts. According to Data for Progress, Black farmers face challenges getting loans, are often denied credit, lack access to legal defense against fraud, and are under threat of violence and intimidation.

Over time, White said, these factors have made it challenging for many to sustain their farm land.

"Farmers of color often have less access to markets, fewer beneficial relationships, and fewer financial resources and opportunities," he said, "which all results in higher rates of debt, lower land ownership rates."

In addition to fostering mutually beneficial connections to enhance food networks across the state, White said there are environmental advantages, too. He highlighted that supporting local farmers reduces greenhouse-gas emissions and minimizes the impact of transporting food over long distances.
