Seth Petersen was at his grandmother’s funeral, and his phone wouldn’t stop ringing.

Three hours away in the village of Luck, Wisconsin, where he served as director of public works, there was an emergency. Petersen was getting calls repeatedly, asking for his expertise.

Petersen and two other employees were responsible for drinking water, wastewater, street maintenance, park and cemetery maintenance and picking up stray dogs, he said. The job never stopped.

“Seth, what the (expletive) are you doing?” his brother-in-law said to him as he came back to the family gathering from another call. “Why are you living like this?”

Petersen left that job at the end of last year. Now, he helps train water operators in small communities for the Wisconsin Rural Water Association.

Luck is not an outlier. In small and rural communities across the U.S., water system operators are stretched thin, covering around-the-clock responsibilities to keep water running safely and reliably despite aging and underfunded infrastructure.

The consequences of a water system falling behind have received the national spotlight, infamously in Flint, Michigan, and most recently in Jackson, Mississippi, where majority-Black communities bore the brunt of mismanagement and aging infrastructure.

Thousands of under-resourced systems risk a similar fate, and small water systems — defined by the EPA as serving fewer than 10,000 people, and making up more than 90% of the nation’s community water systems — are in a particularly precarious position.

Their staffing is often sparse and underpaid. Infrastructure, in many places, is crumbling and underfunded, and though there is a fresh infusion of federal money on the table, it’s a challenge to access.

The American Rescue Plan Act, Bipartisan Infrastructure Law and other programs represent a historic investment in the country’s water infrastructure, totaling billions of dollars.

But the total available funding, even after it’s all been doled out, still won’t be enough. One report from 2020 estimated that the U.S. would need to invest nearly $3.3 trillion in water and wastewater infrastructure projects between 2019 and 2039 to keep systems updated.

Many communities will also face increases in their water bills to keep up with infrastructure and staffing needs. Yet raising the price of water may prove unworkable in rural and historically-underinvested communities like Appalachia and the Mississippi Delta, some of the most impoverished in the country.

No one in the U.S. should have to worry about having safe drinking water, said Chris Groh, executive director of the Wisconsin Rural Water Association.

“But a town doesn’t take care of itself.”

Small community water systems falling behind 

Over the last two decades, water systems in the ten states bordering the Mississippi River violated U.S. Environmental Protection Agency regulations for drinking water more than 438,000 times.

That figure includes thousands of instances of heightened levels of harmful chemicals in water each year. Nitrates, trihalomethanes and haloacetic acids, which have all been linked to various cancers and other health hazards, were top contaminants in the EPA’s violation data in 2022.

Nitrates are an indicator of agricultural runoff, common in rural areas. And trihalomethanes and haloacetic acids appear as byproducts of the water treatment process, when chlorine reacts with organic contents.

Addressing these issues can require expensive treatment technology. But in the last two decades, small and large utilities alike have reined in the number of violations.

However, an Ag and Water Desk analysis of EPA Safe Drinking Water Act violation data nationwide found small water systems have been slower to reduce their violations than larger systems. And these violations only represented those reported; there could be many more incidences of unreported issues.

In the ten states along the Mississippi River, both small and large water systems saw increases in violations newly reported during 2022. For small water systems, that increase was more significant.
