Any substance that is added to drinking water is required to pass rigorous testing to ensure that it meets the high standards that are legislated for the water industry. All HFS received by the City of London is independently tested to ensure that it meets the National Sanitation Foundation (NSF) and American National Standards Institute (ANSI) standards for purity. The NSF/ANSI Standards for fluoride products added to drinking water are even more stringent than the United States Pharmacopeia–National Formulary (USP-NF) Standards that apply to fluoride products used in pharmaceuticals.

• Costa Rica has clean safe drinking water. Unlike Mexico drinking the water is not a problem. However if you are unsure bottled water is available most everywhere.
