What is one common method of disinfection for newly drilled wells?

Chlorination is a widely accepted method of disinfection for newly drilled wells due to its effectiveness in killing pathogens, including bacteria and viruses that could contaminate the water supply. The process involves adding chlorine to the water, which reacts with microorganisms and destroys their ability to reproduce and cause disease. Chlorination is relatively easy to implement and allows for a thorough disinfection of the well system, including the well casing and piping, ensuring that the water is safe for human consumption.

Other methods mentioned also have their uses, but chlorination is particularly favored for well disinfection because it not only disinfects but can also leave a residual chlorine level in the water to provide ongoing protection against recontamination. This makes it a practical choice for maintaining water quality over time after the well has been established.
