The above results are very satisfactory and the figures are within the limits of the
World Health Organisation European Standards for Drinking Water Quality. This
states that the upper limit for lead in running water in the supply should not be more
than 0.1 mg/1 (Pb); but where water undertakings continue to use lead piping the
concentration of lead (asPb) should not exceed 0.3 mg/1 after 16 hours contact with
the pipes.
