* Statistics of the Ministry of Health
The existing monitoring data indicate that pressure of bacteriological pollution on surface waters of
Ukrainian part of the Danube River basin and risk of contagious diseases for population, except of
Zakarpattia region, is rather high including pathogenic microflora. Additionally there are cases of
bacteriological pollution of ground water including mineral springs of Svaliava.

Kolomyia Municipal Wastewater Treatment facilities are overloaded almost by two times. Part of
sewer wastewater is discharged directly into the river Prut without any treatment (about 7
thousands m 3 per day or 2.555 Th. m 3 a year). Needs in increased capacity of sewer wastewater
treatment facilities for the Kolomyia are 30 Th. m 3 per day or 10.950 Th. m 3 per year. For
Kolomyia WWTP it is necessary to construct additional facilities for tertiary treatment.
Chernivtsi municipal wastewater treatment facilities are also overloaded. In 1988 - 1997 it was
planned to complete the construction and introduce additional facilities with capacity 30 Th. m 3 a
day or 10.950 Th. m 3 a year. Emergency discharge from pumping station at Vilde St., is very
serious source of pollution. But lack of sufficient funding from state and local budget prevents the
solution of this problem.
The Izmail wastewater treatment facilities belong to the cardboard factory and receive the
municipal sewer water of Izmail by ratio 1:1. They were also overloaded but during economic
decline when production of Izmail cardboard factory dramatically dropped down, these facilities
can cover existing municipal need for Izmail City. As soon as production increases, the hot spot
will inevitably spread out again with a lot of complications, because of outdated and poorly
maintained technological equipment.
