Fae Saulenas does not want your sympathy. 

Saulenas, along with her 46-year-old daughter Lauren, spent last winter—their covid winter—in Saugus, Massachusetts, in a house without a working furnace. Saulenas is in her 70s. Lauren, because of brain injuries she experienced in the womb, is quadriplegic, blind, and affected by a seizure disorder, among other disabilities. In winter, it’s not unusual for overnight temperatures in Saugus to dip into the teens. The two could not long survive without heat, so absent a furnace, they relied on a space heater. But the cost of electricity to power it was $750 in February alone, and it warmed only a single bedroom.

Saulenas doesn’t tell this story to engender sympathy but, rather, as a warning. The water table, she says, is rising—seeping into gas lines and corroding furnaces from the inside out. That’s what happened to hers. And she wants you to know that if you live anywhere near a coast—even one, two, three miles away—that water might be coming for you too.

For something you’ve probably never heard about, rising groundwater presents a real, and potentially catastrophic, threat to our infrastructure. Roadways will be eroded from below; septic systems won’t drain; seawalls will keep the ocean out but trap the water seeping up, leading to more flooding. Home foundations will crack; sewers will backflow and potentially leak toxic gases into people’s homes. 

Saugus is a small town roughly 10 miles northeast of Boston. On maps, water is one of its defining features, with the Saugus River and its tributaries meandering through the town and heading through marshland to the Atlantic Ocean. Among those salt marshes, blocked from the Atlantic by the peninsula of Revere Beach, is where Saulenas bought her house in 1975. 

Given the proximity to the ocean, the source of her recent woes would seem obvious: sea-level rise. Since 1950, sea level in the region has risen by eight inches, and that change has not been linear. The sea is rising faster now than it did a generation ago—about an inch every eight years. But the water that left Saulenas out in the cold did not come from the sea, at least not directly.

Her problems began in 2018, when she lost gas—and thus heat—because of water entering an underground main. It was a problem that would persist, intermittently, for several years. Water would enter the gas main, and her utility, National Grid, would be forced to shut off the gas. National Grid would then try to find where the water was coming from, patch the leak, and pump the water out. 

Officially, National Grid has not named the source of the problem. But Saulenas thinks the culprit is groundwater.

Even under normal circumstances, the cast iron pipes that make up roughly a third of National Grid’s infrastructure in Massachusetts are prone to rust and corrosion. She thinks these pipes, which once sat comfortably above the water table, are finding themselves intermittently swamped during seasonal high tides that essentially push up the groundwater. And it’s that elevated groundwater that she thinks seeped into the gas main, flooded out her gas meter, and eventually corroded her furnace. 

“The problem is huge. We’ve way underestimated the flooding problem.” 

Kristina Hill, an associate professor at the University of California, Berkeley, whom Saulenas reached out to in pursuit of answers, agrees. “She was asking me, is this something that comes from sea-level rise? And obviously, the answer is yes,” says Hill. 

Hill is one of a number of researchers trying to get the public and policymakers to take the risks of rising groundwater seriously. Unlike rising seas, where the dangers are obvious, groundwater rise has remained under the radar. Hydrologists are aware of the problem and it’s all over the scholarly research, but it has yet to surface in a significant way outside of those bubbles. Groundwater rise is only briefly mentioned in the most recent edition of the National Climate Assessment, released in 2018; it’s absent from many state and regional climate adaptation plans, and even from flood maps.
