Well Chlorination in Brunswick, ME
Call (800) 696-9355 or request a visit. Monday to Friday, 8:00 AM to 5:00 PM.
Opening a wellhead for a pump replacement or repair gives bacteria a way in. In Brunswick, we recommend shock chlorination afterward as a standard precaution, and a test a week or so later to confirm everything is clean.
Well Chlorination for Brunswick homes
Brunswick is a Midcoast college town on the Androscoggin River and Casco Bay, with village streets and a lot of rural land at its edges. Coastal ground mixes bedrock, clay and sand, and wells near the water can pick up sodium and chloride over time.
Drilled wells in rock can bring arsenic, uranium and radon, and a lab test is the only way to know which apply to a given lot. Anyone buying in Brunswick on a private well should ask for a recent test and look at what treatment is already in the basement.
What we see in Cumberland County wells
Shallow sandy wells near the water can pick up bacteria after storms and high water. In Brunswick, a well near Brunswick and the Casco Bay side of Midcoast that tests positive after a coastal storm is a good candidate for shock chlorination and a closer look at the wellhead.
What we check first in Brunswick
- Total coliform and E. coli before and after treatment
- Casing inspection for cracks or gaps
- Plumbing and heater protection before the dose goes in

How it works
How we handle well chlorination, step by step
- 1
Inspect the well
Before any chlorine goes in, we check for obvious issues: a loose cap, a flooded pit or a leaking splice. The goal is a lasting fix, not just a temporary one.
- 2
Dose and circulate
Equipment that could be harmed is bypassed, and water softeners and filters are handled appropriately. The goal is to disinfect without damaging anything in your Brunswick house.
- 3
Hold and flush
We plan the flush so that it does not overload the septic system or harm the garden. Where there is a risk, we suggest an alternate discharge path.
- 4
Retest the water
A bacteria sample is taken after the flush, usually after a few days, to confirm the water is clean. We send it to the lab and review the result with you.

What shapes the job in Brunswick
Chlorine affects equipment. Water heaters, softeners and filters can be damaged or have their media affected, so we bypass or protect them as needed. In a Brunswick basement, that is planned before the chlorine goes in.
When to consider shock chlorination
- A pump replacement or well repair has just happened
- A camp or cottage is reopening for the season
- A well that has been unused for a long time
- A family member with an immune concern
