This dataset covers water quality at coastal sites in Wales, collected
under the terms of the European Bathing Water Directive by
Natural Resources Wales (NRW).
Water samples are taken at designated bathing water sites each week from
May to September. An analysis of these sample results over four years
produces an annual water quality classification for each bathing water.
In 2014, all of the bathing waters in Wales were compliant under
the Bathing Water Directive. This is the best overall result in the UK.
The Welsh bathing water quality data is available through an API, and is
openly licensed under the
Open Government Licence
. We also provide an application to allow you to explore elements of
the data via the profile held on each bathing water, and a widget application
which allows you to put a live feed of bathing water quality information
on your own web site.
