Reference – Flouride Concentrations in British Water

The concept of water fluoridation remains controversial and the evidence supporting it remains weak. An increasing number of individuals have chosen to avoid consuming fluoride. The data below relates to the research conducted by Zohouri et al (2003), WMAF (2011) and information supplied by the water providers themselves (eg Thames Water). It is not practical to provide an exact figure for municipal water supplies do to natural variation in levels of calcium flouride.

The only areas of the UK that are artificially fluoridated currently are Southampton, the West Midlands and the North-East. Note that 1ppm is equal to 1mg/L. In my opinion, the flouride content of your water you drink should average out below 0.3ppm. The maximal concentration that the UK Government allows is 1.5ppm. It should also be noted that there are more concerns to tap water than just the flouride content (eg recycled contraceptive hormones and pharmaceutical drugs).
