1999), the concentration of raw water natural organic matter (NOM) in the Boreal
region (Latvia) is high and its removal during conventional water treatment is
complicated. The high ... A water distribution system (DS) can be characterized
as a biological and chemical reactor that interacts with water in the network (
Gauthier et al. 2001) which results in ... NOM's influence on water quality change
is usually related to biodegradable organic carbon (BDOC) in drinking water.

In Sweden we now have new guidelines for the quality of drinking water. In the
former guidelines it was not pointed out clearly enough that the water should be
prepared for both human consumption and the distribution network. The new
recommendations consider, for some parameters, raw water quality and give
recommendations for the prevention of corrosion as well. Extra attention is paid to
the presence of organic matter, both natural organic matter (NOM) and also trace
