A picturesque Massachusetts town is facing a sewage crisis residents have dubbed a “doomsday scenario,” with experts warning that contaminated drinking water could eventually make its historic village center uninhabitable.
uncertain
center → face → crisis
Carlisle, located about 20 miles northwest of Boston, has no public water supply or municipal sewer system.
asserted
Carlisle → locate → supply
Instead, residents rely on private wells and backyard septic systems, many of which are aging.
asserted
many → rely → which
The problem is particularly concerning in the historic village center, where homes and businesses sit close together on small lots, some about the size of three basketball courts.
asserted
homes → sit → courts
Conventional septic systems filter wastewater through surrounding soil, but limited space and the town's fractured bedrock can make it easier for contaminated wastewater to reach nearby drinking wells.
asserted
wastewater → filter → wells
The contamination has already raised concerns across the community.
asserted
contamination → raise → community
Wells at Ferns Country Store, a general store that served Carlisle for more than 180 years, and Town Hall tested positive for E. coli in 2021 and 2023.
asserted
that → serve → 2021
The bacteria was also detected in the local public school's well last fall, while nitrate levels at the public library exceeded drinking water standards in 2016, according to an investigation by The Boston Globe.
uncertain
levels → detect → Globe
Susan Murcott, a wastewater expert and lecturer at the Massachusetts Institute of Technology, warned that if the situation remains unaddressed, it could become "deadly" in the coming decades.
uncertain
it → warn → decades
When asked by the Globe whether she meant the crisis could threaten property values, Murcott clarified that the danger was "to human beings."
uncertain
danger → ask → beings
The issue has gained renewed attention after Ben and Amy Pirri, a couple who moved to Carlisle during the COVID-19 pandemic, attempted to purchase and reopen Ferns, which closed in 2025.
asserted
which → gain → 2025
The couple initially expected to reopen the business without major complications.
asserted
couple → expect → complications
"We'll just turn it back on," Ben Pirri recalled thinking, he told the Globe.
asserted
he → turn → Globe
Instead, they discovered the property could not accommodate a conventional septic system without potentially contaminating nearby wells.
uncertain
property → discover → wells
Ferns relied on a composting toilet because there was insufficient space to safely dispose of wastewater through a traditional septic system.
asserted
Ferns → rely → system
The Pirris initially set out to reopen Ferns as a cafe and community gathering place, but eventually expanded their efforts into a proposal to address the village's broader wastewater problems.
asserted
Pirris → set → problems
The store remains closed for now.
asserted
store → remain → ?
They suggested connecting the property to an existing, town-owned wastewater treatment plant serving the public school, which would require approximately 2,100 feet of piping.
uncertain
which → suggest → piping
Town administrator Ryan McLane initially called the idea a "moonshot," but subsequent investigation found the school's treatment plant had unused capacity that could potentially accommodate additional wastewater, according to the outlet.
uncertain
that → call → outlet
McLane declined The Independent's request for comment.
asserted
McLane → decline → comment
The proposal has faced resistance from officials and residents concerned about the cost of new infrastructure and its potential impact on Carlisle's historic character.
asserted
proposal → face → character
Some fear a municipal sewer system could encourage development and undermine the town's rural appeal.
uncertain
system → fear → appeal
During a May 27 Board of Health meeting, board chair Patrick Collins dismissed the possibility of constructing a municipal wastewater system, calling it "such a pipe dream."
uncertain
Collins → dismiss → it
Pirri pushed back, asking: "Is Carlisle town center not somewhat in crisis?
asserted
center → push → crisis
Do we not need a better solution for wastewater in town?
asserted
we → need → town
You don't think so?"
asserted
You → think → ?
The controversy intensified after Pirri questioned an unexplained increase in wastewater passing through the school's treatment plant between November 2025 and March 2026.
asserted
Pirri → intensify → November
Records showed approximately 750,000 gallons of excess wastewater effluent passed through the facility during that period, according to the Globe.
uncertain
gallons → show → Globe
Pirri suggested illegal dumping could have contributed to the increase.
uncertain
dumping → suggest → increase
However, town officials and the private company operating the facility said they could not determine the cause and denied that illegal dumping had occurred.
uncertain
dumping → operate → cause
After the Select Board declined to fund an engineering study examining the proposed connection, the Pirris offered to personally cover its $55,700 cost.
asserted
Pirris → decline → cost
Their efforts have since gained support from residents, with the local library committee also expressing interest in connecting to the school facility.
asserted
committee → gain → facility
The Select Board has agreed to hold a townwide vote on November 16 to determine whether public money should be spent developing engineering and design plans for sewer pipes connecting the village center to the existing treatment plant.
asserted
money → agree → plant
