Is the water safe to drink?...
We've taken several trips to Bonaire and never had to worry about the water quality and we never had any problems.
However, recently there have been 2 outbreaks associated with the water but it appears that the authorities have taken action to address the situations quickly, see the links below.
One incident was sewage contamination of the drinking water in Belnam caused by the unorthodox practices of an amateur plumber.
The other was an outbreak of Legionella (a respiratory disease caused by inhaling contaminated aerosolized water) but it looks like they responded quickly to that too.
I would feel comfortable about drinking the water in Bonaire.
