Reference is made to your letter of 5 February
concerning the use of asbestos cement pipes.
As requested , I would like to confirm the position
of the Organization concerning the use of such pipes for drinking
water supply. Research findings up to date are too inconclusive
to demonstrate a health effect from ingested asbestos fibres via
drinking water. Consequently, we consider it appropriate to continue
the use of such pipes for water supply networks. Their use is
particularly important in the case of developing countries where
they constitute an economical construction material for supply networks.
