Appreciate all the replies. The previous owner said he dumped a gallon of bleach
into the well via the removable cap once a year to clean the well, improve taste
and to remove bacteria. Just wanted to continue with his instructions. However,
as I can not see any problem thought it would be best to ask those with
experience if this was a required routine.

Breaking the cap seal on a clean well is a really bad idea as it raises the
potential for bacterial contamination. Throwing a gallon of bleach down the well
does not prevent this unless you completely cover the entire interior casing and
cap.
