Chlorinating a well is not just pouring in bleach. For a York County home, the dose is calculated from the volume of the well and plumbing, circulated properly and given time to work, with a follow-up sample to verify it.
Well Chlorination for Kennebunkport homes
Kennebunkport is a coastal town of harbors, headlands and shaded country roads, with a mix of year-round and seasonal homes. Many properties outside the central areas rely on private wells, often drilled into the bedrock under a thin layer of soil.
Salt is a real consideration here, and wells close to tidal water can show changes in sodium and chloride after a dry spell. Kennebunk and Arundel lie next door, and Wells and Biddeford are a short drive away, which keeps coastal York County within one route.
What we see in York County wells
Shallow sandy wells near the water can pick up bacteria after storms and high water. In Kennebunkport, a well near the Kennebunkport coast and its back roads 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 Kennebunkport
- Nitrate, which can point to septic or fertilizer influence
- Drainage around the well, to see where water collects
- The septic system's distance and condition

How it works
How we handle well chlorination, step by step
- 1
Inspect the well
We also review your last test results and note what prompted the chlorination, such as a positive coliform, a repair or a flood.
- 2
Dose and circulate
A measured dose of chlorine is introduced into the well and circulated through the plumbing, with a hose back to the well to mix it. Every tap and fixture is run until chlorine is detected.
- 3
Hold and flush
Patience matters here. We hold the solution long enough to be effective, then flush until the chlorine smell is gone and the water runs clear.
- 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 Kennebunkport
If bacteria return, chlorination alone is not the answer. A failed casing, a cracked cap or a nearby source needs to be found. We look at the whole well so a York County homeowner does not repeat the process without cause.
When to consider shock chlorination
- The wellhead was flooded or submerged
- A camp or cottage is reopening for the season
- Slime or odor that may point to bacteria in the plumbing
- A family member with an immune concern
