Amherst, Massachusetts, will apply the same clean energy setback protections to private wells that it uses for public drinking water sources.
According to the Daily Hampshire Gazette, the Town Council unanimously adopted an updated Small Clean Energy Infrastructure Bylaw after approving amendments that tightened required distances from wells and reservoirs for solar arrays and battery energy storage systems.
Here's what to know
For solar projects, the town added 200-foot no-disturbance zones around every drinking water source. Battery storage facilities must be kept 400 feet from wells and reservoirs.
District 2 Councilor Lynn Griesemer proposed the change, saying residents served by private wells deserve the same safeguards as people on the public water system. The biggest concentration of those wells is in Amherst's northeast corner, and they supply about 5% of homes.
"I'm respectfully asking that those wells be treated just the same way that any public water source is," Griesemer said, per the outlet.
Backers linked the measure to well protection and concerns about forests and groundwater.

District 1 Councilor Jill Brevik said solar construction could affect private wells through tree clearing as well as the use of herbicides and cleaning solvents.
"I think that there are good reasons for setbacks from public water sources," Brevik said, per the Daily Hampshire Gazette. "I think that the same rationale should be applied to private water sources, and I don't see why we would have a distinction between the two."
Councilors approved the solar buffer for private wells 7-5 and the battery storage setback 8-4, then adopted the full bylaw.
More background
The vote exposed a familiar tension in local climate policy: how to protect land and water without making clean energy projects too difficult to build.
District 3 Councilor George Ryan argued that the expanded setback could take more land out of consideration than it might seem. He also said he had not seen evidence showing these projects pose a groundwater threat to private wells.
"There's no evidence, there's no concern, it seems simply to be a fear," Ryan said, according to the outlet. "Now if there's evidence, I'd like to hear it."
Stephanie Ciccarello, the town's director of sustainability, raised a similar point. She said the bylaw already includes erosion controls, stormwater management standards, and restrictions on herbicide use.
"Just talking about a distance in and of itself is not going to offer a protection," Ciccarello said.
Planning Board Chair Doug Marshall also cautioned that expanding the solar buffer from 100 feet to 200 feet around private wells could make some projects economically infeasible, particularly on the small parcels common in Amherst, as the Daily Hampshire Gazette noted.
What's being done?
Amherst's bylaw is meant to create a clearer path for solar and battery developers.
The measure established a consolidated permitting process and siting rules intended to comply with state law set to take effect Oct. 1.
District 4 Councilor Pam Rooney, who chairs the Community Resources Committee, said the structure sets out a straightforward process and enforceable rules for operation and removal while still supporting safe clean energy development.
The amendments drew support from Smart Solar Amherst, which argued that failing to make the change would disadvantage residents who rely on private wells and leave the northeast section of Amherst less protected.
District 2 Councilor Amber Cano-Martin said the vote was an effort to protect both Amherst's climate goals and the landscape the town depends on.
"I think we need both: I think we need solar energy and we need to keep our forests, because in terms of mitigating climate change, having forests is a major factor in that," Cano-Martin said, per the Daily Hampshire Gazette.
