A policy meeting is due to report soon on the pool volume it’s also excellent for
trends against high uses of chlorine in
pools. It is thought to support more
research into chlorine alternatives and to
provide access for funding for safer options.
REACH deals with the Registration,
Evaluation, Authorisation and Restriction of
Chemical substances. The new law came
into force on 1 June 2007.
The use of chlorine is known to be “on
the agenda“ of both the EU and the World
Health organisation and the indications are
that the new body will flex its muscles later
this year.
“There is no concern about being anti
chlorine and REACH has to look at things
over a longer period but it is safe to say
that natural alternatives, even those which
may need a chlorine boost are more likely
to be favoured over the next five years,”
said a EU statement.
While smaller domestic pool owners are
switching to chlorine free alternatives, the
local authority and commercial pools are
unlikely to switch until there is a major
policy change from an organisation such
as PWTAG. spn
