Shock chlorination is how we disinfect a well and the plumbing it feeds. In Kennebunk, it is the standard response to a positive coliform test and a routine step after pump work, well repairs or a flood that may have let surface water in.
Well Chlorination for Kennebunk homes
Kennebunk includes a historic village, the Mousam and Kennebunk rivers, long beaches and wooded country roads running back inland. Homes away from the village center are generally on private wells, drilled or dug depending on the age of the house.
Shore-side properties can see sodium and chloride in wells after long dry periods, which is worth knowing before choosing treatment. Bedrock wells in southern York County regularly raise arsenic, uranium and radon questions that only a lab test can answer.
What we see in York County wells
Shallow sandy wells near the water can pick up bacteria after storms and high water. In Kennebunk, a well near Kennebunk's river valleys and coastal edge 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 Kennebunk
- Chlorine residual during the process, to confirm it reached every tap
- Wellhead and cap condition, a common entry point
- 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
We calculate the volume of the well and house plumbing, add the right amount of chlorine and run it through every line, hot and cold, so no part is missed.
- 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
We suggest a second test a few weeks later if the original problem was serious. That extra step is cheap insurance for your York County well.

What shapes the job in Kennebunk
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
- A positive total coliform or E. coli test
- The water has a musty or unusual smell
- A change in taste after a storm or thaw
- A real estate test that came back positive
A positive bacteria test in Kennebunk is fixable. Call, and we will explain how the process works and what to expect.
