Table 2.10.
insufficient capacity of wastewater treatment facilities for current situation,
poor condition of the sewer system
large emissions discharge into a river with a small discharge especially in
seasons with low water level; outdated technological equipment resulting in
bacteriological pollution;
scarcity of aquatic organisms in the vicinity of the hot spot in Uzh river;
possible pollution by pathogenic microflora
does not effect drinking water supply; effects ecosystem and aquatic life of
downstream rivers, recreation and sport fishing;
may have transboundary impact on water users in; may be a source of
bacteriological pollution
high priority

Implications
Rank
insufficient capacity of wastewater treatment facilities; potentially pollution
will increase along with improvement of economic situation
a large emissions discharge into a river with a small discharge especially in
seasons with low water level; poor condition of sewer system
scarcity of aquatic organisms in the vicinity of the hot spot in Prut river
effect drinking water supply; effects ecosystem and water life of downstream
rivers, recreation and sport fishing;
risk of transboundary impact on water users in Moldova and Romania is very
low
