If you sift through the notes you will find the epa rules and cfrs which state a sliding sample timeline based on flushing frequency with a minimum of 1 sample annually for the most frequently flushed/cleaned tanks

The increased sampling is parallel to municipal and groundwater testing rules for coliforms in the two step process. First test for general coliforms (which may not be harmful) then retest for e coli which is.
Whether you deem water as safe or not there were 62 e coli samples in the major airlines from 2012-2019 . So 7.75 per year. Of that 3 were United. 0.375 per year.
