Following our post about fluoride contamination last week, our water series is now focused on the equally serious problem of arsenic contamination. Some arsenic is present in all groundwater sources (see table 1). Of course this is only a problem if the arsenic has the chance to leak into groundwater as it filters through the rock. Arsenic leaching is more likely to occur in groundwater that is ho ...[Read More]
Water Series (2): Fluoride Contamination in Drinking Water

In some parts of the UK we add fluoride to our drinking water, because small amounts can help to protect your teeth.
