Which of the following is NOT part of the actions taken after a positive fecal coliform sample in a pool?

The correct answer is that increasing pool capacity is not part of the actions taken after a positive fecal coliform sample in a pool. When a fecal coliform presence is detected, it signals potential contamination that poses health hazards to swimmers.

In such instances, hyperchlorination is important as it significantly raises the chlorine level temporarily to disinfect the water effectively, handling the contamination. Closing the pool is a necessary precaution to prevent further exposure to swimmers while addressing the contamination issue. Additionally, removing any fecal matter is a critical step to eliminate the source of the contamination entirely before reopening the pool to ensure the safety of all users.

Increasing the pool capacity does not address the problem of coliform contamination and can lead to more significant public health risks. Instead, the focus should be on sanitation and disinfection to eliminate pathogens.
