Opening a wellhead for a pump replacement or repair gives bacteria a way in. In York, 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 York homes
York runs from rocky headlands and beaches back through woods and farmland to the Berwick line, and much of the town has no public water. Wells here are commonly drilled into folded coastal bedrock, where water travels through cracks rather than through porous soil.
Rock wells in granite country can carry arsenic, uranium or radon, and from the road there is no way to guess which lots do. A buyer in York should treat the well as part of the inspection, and a rock well deserves arsenic and radon results.
What we see in York County wells
Shallow sandy wells near the water can pick up bacteria after storms and high water. In York, a well near the York shoreline 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 York
- Chlorine residual during the process, to confirm it reached every tap
- Casing inspection for cracks or gaps
- 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
The chlorinated water sits for the required period, typically many hours. After that, we flush it out through an outdoor hose, away from septic systems and sensitive plants.
- 4
Retest the water
A clean result closes the loop. If it comes back positive, we look deeper at the cause and discuss next steps, such as repair, additional treatment or ongoing disinfection.
What shapes the job in York
Dose and contact time are the heart of the process. We calculate how much chlorine the system needs, circulate it until it reaches every tap and let it stand for the time the job requires. Rushing the hold leaves bacteria behind.
When to consider shock chlorination
- A pump replacement or well repair has just happened
- The water has a musty or unusual smell
- Slime or odor that may point to bacteria in the plumbing
- A real estate test that came back positive
