A state that still drinks from springs

About four out of ten Vermont households get their drinking water from a private well or spring, and the inclusion of springs in that sentence is not a technicality. Vermont recognises three main private drinking water sources: drilled wells, dug wells and springs. They are genuinely different things and they fail in different ways.

A spring is groundwater emerging naturally at the surface. That makes it surface-influenced by definition, and it is difficult to keep a spring free from bacterial contamination. Where a deep drilled well has a great deal of rock between it and whatever is happening on the ground, a spring has very little. Protecting the spring head from surface runoff, animals and debris is ordinary maintenance rather than an unusual precaution, and regular bacteria testing matters more here than it would on a drilled well.

The broader contaminant list applies to all private sources: bacteria and viruses from septic waste, naturally occurring chemicals including arsenic and manganese, petroleum products, pesticides and radiation. Testing on a schedule rather than once is the sensible response, because a shallow source changes with the season and the year in a way a deep one does not.

Drought finds the shallow sources first

Vermont does not think of itself as a place with water shortages, which is exactly why the dry years catch people out.

When shortages have been reported here, the large majority of failures were in shallow dug wells and springs rather than in drilled wells. The reason is simply depth. A spring or a shallow dug well draws from water near the surface, and that is the water that drops first when the table falls and recovers last when it comes back. A drilled well reaching deeper groundwater has substantially more buffer.

The practical implication is worth acting on before the next dry summer rather than during it. If a property has lost water more than once in a dry spell, that is a pattern rather than bad luck, and deepening the existing source or drilling a new one is worth costing out while there is no urgency about it.

The failure nobody insulates against

Vermont homeowners generally know to insulate indoor pipe runs. The failure that gets far less attention is at the other end of the system.

A frozen well pump or line does not merely inconvenience you. It stops the water supply completely, drops pressure, and can damage the pump motor or the pressure tank, both of which cost considerably more to replace than a section of split copper. The equipment sits in a well house, a pit or an unheated corner of a basement, and it is easy to forget precisely because it is out of sight and has always worked.

The preventive steps are straightforward. Insulate the well house or pit properly. Keep the pressure tank in a heated space where the layout allows. And if there is a heat source in the well house, confirm before winter that it actually works rather than assuming it does, in the same way you would test heat tape.

There is a related point about specification that is worth raising with anyone doing work for you. Code minimums for burial depth and insulation are written to cover a range of conditions, and in Vermont’s coldest northern counties a specification that is technically compliant can still be functionally inadequate. On new work, a renovation, or a service line replacement in the north, asking for better than the minimum is a reasonable request rather than gold-plating.

The Champlain valley exception

One last thing sets Vermont apart from its neighbours, and it is a useful correction to regional assumptions.

Most of New England sits on crystalline bedrock that gives up very little mineral, which is why the region has famously soft water and why softeners are usually the wrong purchase there. The Champlain valley is different. Extensive limestone and dolomite bedrock underlies it, and that raises hardness in both municipal supplies and private wells in the area.

So advice about soft water that holds across most of New England does not automatically transfer to Burlington and the valley. Vermont’s geology changes over relatively short distances, which is the strongest argument for testing at your own tap rather than relying on what is generally true of the region. Every plumber we dispatch in Vermont works to the state’s licensing and inspection requirements administered through the Division of Fire Safety.
