Plumbers in Maine

A known problem that mostly goes unfixed

Maine has an unusual water situation, and the unusual part is not the contaminant. It is the response to it.

About one in ten wells in Maine has arsenic above the drinking water standard, and in parts of central and southern Maine, where the bedrock naturally releases it into groundwater, the proportion is higher still. That figure alone would make testing worthwhile. What makes it a genuinely Maine story is what happens afterwards.

A survey of central Maine households found that only forty-three per cent had installed arsenic treatment three to seven years after being notified that their well exceeded ten micrograms per litre. In other words, a clear majority of people who had been told their water had a problem were still drinking it years later.

There are understandable reasons. Arsenic has no taste, colour or smell, so nothing in daily life reinforces the result. Treatment costs money. The notification arrives once and then life continues. MaineHousing has for nearly a decade run programmes helping lower-income homeowners test and treat their wells, though the programme has reached fewer households than intended as costs rose and criteria changed.

If you have an old result sitting in a drawer, that result is almost certainly still accurate. Arsenic in bedrock is geological, not episodic. It does not clear up.

Why the well type matters

Maine’s reliance on private water is high. Roughly half the state’s population draws from a private source, and more than seventy-five per cent of those are drilled bedrock wells.

That detail is not incidental. A bedrock well goes down an average of around two hundred and fifty feet to reach groundwater held in fractures within the rock, and water sitting in prolonged contact with rock dissolves whatever is in that rock. Where the bedrock contains arsenic, the water picks it up. A shallow dug well drawing from soil water has a different exposure profile altogether, along with its own separate risks around surface contamination.

So when you are interpreting a test result or deciding what to test for, knowing which kind of well you have is the starting point rather than a technicality.

Winter, and the outage inside it

The other half of Maine plumbing is the season, and the specific hazard is less the cold itself than the power cut that accompanies it.

Maine’s older housing routes pipe through crawl spaces, unheated basements and exterior walls, spaces that stay below freezing for months rather than for a night. In normal operation the house’s heat keeps them survivable. A nor’easter that takes the power down for a day or two removes that, and lines which would comfortably handle an ordinary January night freeze instead.

The preparation is ordinary and it belongs in October. Insulate every accessible run in an unheated space. Disconnect the hoses. And confirm that your main shutoff actually turns, because the moment you need it will be in the dark, without power, with water arriving.

Camps, and the thing that has to be drained

Maine’s seasonal property stock is substantial, and a camp closed carelessly is the most reliably predictable failure in the state.

Turning the thermostat down is not closing a house. Draining is. That means shutting off at the main, emptying the supply lines from the lowest point until they are genuinely empty, draining the water heater, and putting non-toxic antifreeze into every trap including floor drains and toilets. On a well, the pump and pressure tank need attention too.

Leaving the heat on low is a reasonable belt-and-braces addition on top of all that, and a poor substitute for any of it, because the scenario that produces the worst damage is a heating failure in a house that still has water in its lines. Every plumber we dispatch in Maine holds the state licence and pulls the local permit for work that requires one.
