<p> This dataset is a record of annual water
fluoride concentrations in Lower Super Output Areas (LSOAs) in England from
2009 to 2020. </p><p> </p><p>We obtained
information on the fluoride concentrations for each water supply zone through
requests made under the Environmental Information Regulations 2004, to water
companies in England. The Water Supply (Water Quality) Regulations SI 2016/614
require that water companies take a minimum of 1-8 annual samples per water
supply zone, per year (dependent on population size) of water fluoride concentrations,
as part of routine water quality monitoring. </p><p> </p><p>This dataset was
created by merging the supplied information on annual fluoride concentrations
in each water supply zone, with the 2011
LSOA population-weighted centroids (Office for National Statistics). </p><p> </p><p>
</p><p>Further details on
the methods used to create this dataset will be found in the Research paper
accompanying this dataset</p>
