Why each page exists
A page is published only when it helps with a distinct property decision: understanding a system, setting urgency, comparing options, preparing for an estimate, or clearing due diligence before a purchase. Town guidance addresses the local service boundary, soil context and permitting questions relevant to that location.
How factual claims are checked
State, regional and health statements are checked against first-party sources (the Vermont DEC wastewater program and Rules, the Department of Health’s drinking-water guidance and the regional permitting offices), and those sources are linked on the resources page so you can verify them yourself.
Where isolation distances come from
Minimum distances between wells, septic tanks, leachfields, property lines and other features are set in § 1-912 (Table 9-3, wastewater systems, and Table 11-2, isolation zones) and § 1-1104 (Table 11-1, potable water supplies) of the Vermont Wastewater System and Potable Water Supply Rules, in the edition dated November 6, 2023 with 2024 corrections. The Secretary can reduce or increase a distance for a particular site.
The setback, rules and well-siting pages state the main distances, each with its table and the edition, and link the Rules so you can check them. Confirm the distance for a specific lot and work date with the regional permitting office or a licensed designer.
What is left to the site visit
Website content cannot evaluate your soil, find your water table, certify a system as compliant, or design a replacement. Those must be done for the actual property by a licensed professional, and this site says so wherever the decision is one of them.
How a page is kept current
Each guidance page carries a review date, and a material correction changes both the page and that date. The Vermont Wastewater System and Potable Water Supply Rules were reissued in a November 6, 2023 edition with 2024 corrections, so pages that describe permits, designer classes or isolation distances are read against that edition. When the state changes a rule, the affected pages are re-checked, not just the date.
