Disperse the disinfection solution evenly throughout the well, including the bottom of the well.

Well disinfection is a part of every planned maintenance effort.
However, there are many times when we are faced with a potential compromise or failure of the well and an emergency response is necessary. This is most common in flooding situations but can occur for a variety of reasons—vandalism, accidents, and other forms of natural disasters.
Depending on the circumstances surrounding the compromise or failure, other hazards may be lurking at the well site, such as damaged electrical wiring. Before addressing disinfection, you should address these challenges. Once access and power to the well site has been restored, you can safely focus on the issue at hand—well disinfection.
