Littleton Board of Health debates private‑well testing rules, cost and enforcement scope

The Littleton Board of Health spent much of its June 10 meeting drafting rules for private drinking wells, focusing on which contaminants to test for, how often tests should be done, and when the board could require tests or remediation.

Chair Kevin Davis opened the item and asked Francis to recap the draft, which the board said is based on model requirements from state guidance. Francis said the draft pulls testing parameters from those model requirements and that he would look for a state guideline the board could cite as rationale.

Libby Donigan pressed the group to include volatile organic compounds (VOCs) in the testing list. "If we're testing for the chemicals the document calls ‘PAS,’ I don't know why we wouldn't necessarily test for VOCs in the drinking water," she said, and volunteered to draft a recommended testing‑cycle table for the next meeting.

Board members discussed bundling tests to reduce per‑sample cost. Participants estimated bundled panels could run in the low hundreds of dollars every 3–5 years, while a VOC‑only panel could be substantially more; board members described these figures as approximate. Francis said some labs offer bundled PFAS (the transcript uses the shorthand "PAS") and VOC analyses, and that he could pull model language from state guidance.

Several members flagged a procedural issue: including "should" language (recommendations) inside regulations can create confusion. "Regulations are 'thou shalt' or 'thou shalt not,'" a member said, arguing that advisory content may be better published as a separate one‑pager or outreach piece. The group agreed to explore separating guidance (recommended cycles and how to sample) from the regulatory text while keeping mandatory triggers in the regulation.

Members also debated the board's enforcement scope. The draft includes a clause that "the board of health may require more frequent testing" where conditions warrant; supporters said it is a necessary "escape clause" for known or suspected contamination, while others warned it could become an unfunded mandate without clear, specific triggers.

On testing logistics the board discussed whether required samples should be collected post‑remediation for properties with treatment systems and whether owners should submit test results to the board only when testing is mandated. The draft language under review would have owners make results available to tenants and to buyers in property transfers; members discussed limiting the look‑back window for required disclosures (for example, recent results rather than decades of historical tests).

The board also reviewed a separate irrigation‑well provision proposing annual E. coli and nitrate testing for wells used for watering or agricultural production. Several members questioned the policy distinction when a single well serves both domestic and outdoor uses and asked Francis to check whether state agencies already require agricultural wells to be tested.

Next steps: Libby Donigan will prepare a recommended testing‑cycle table, Dan Kaine will draft clarified regulatory language on triggers and submission requirements, and Francis will search for and propose state guidance language and any relevant Department of Agriculture or DPH requirements. The board set the item as continued for future meetings.

The discussion emphasized tradeoffs among public‑health protection, procedural clarity, and the financial burden on household well owners; the board asked staff to return specific wording that both protects public health and clearly defines when the town may require testing or remediation.
