A Two-Track Classification System
Vermont's classification reflects the state's overwhelmingly small, rural water system landscape:
- Groundwater ladder (Class 1A, 1B, 2, 3): Graded by treatment complexity rather than population, reflecting that most Vermont systems are small groundwater-sourced systems where treatment sophistication (not customer count) is the better predictor of operator competency needed.
- Surface water / groundwater-under-direct-influence (GWUDI) ladder (Class 4A, 4B, 4C): Classified by population served — 4A (25-500), 4B (501-3,300), 4C (3,300+) — since surface water treatment inherently requi
