British researchers called Kiev the dirty capital of Europe. The main problems of the city, they identified landfills and gassed air, but the biggest trouble - water. "Kievvodokanal" purifies the water from the Desna several times with chlorine and filters. However, Vladislav Goncharuk, Doctor of Chemical Sciences, Academician of NASU and Director of the Institute of Colloid Chemistry and Water Chemistry, does not dare to drink such water. "Tap water is not drinking, it is really of very poor quality - it does not cause any doubts," the scientist claims.
