Heat Intensifies Strain Around Local Data Centers

The AP reports that Lowell resident Eileen Castle, 82, has stopped filling her backyard swimming pool because a Markley Group data center behind her house runs industrial air conditioners and backup diesel generators that emit fumes at unpredictable hours. Castle told the AP, "I think about the air quality, the water, what effects it has on the kids in the area." The AP report, carried by the Winnipeg Free Press, does not include a response from Markley Group about the facility's operations or mitigation measures.

Castle's account fits a pattern reported independently across Massachusetts through 2026. Boston Globe and WBUR reporting describe growing resident pushback against data centers sited close to homes, citing cooling-tower noise, generator fumes, and water use. CBS Boston reported that neighbors near the same Lowell facility, described as the largest data center in Massachusetts, say its air conditioning sounds "like jet engines" during hot weather. In March 2026, Lowell became the first Massachusetts city to impose a moratorium on new data center construction, and residents separately filed what was reported as the state's first lawsuit against a data center operator and state environmental regulators.

The throughline for infrastructure and sustainability teams is that extreme-heat scenarios need to be modeled as a community-relations and permitting risk, not only a cooling-capacity problem. Facilities sited near residential areas face compounding scrutiny during heat waves: higher chiller and generator duty cycles raise both energy draw and local emissions and noise complaints, which can accelerate moratoriums, permitting delays, or litigation in the jurisdictions where AI operators most need to expand.

Watch for outcomes in the Lowell lawsuit against Markley Group and Massachusetts environmental regulators, whether other Massachusetts municipalities follow Lowell's moratorium, and whether Markley Group or other operators publicly respond with mitigation commitments such as quieter cooling technology, generator emissions controls, or community agreements.
