Why did water change its colour?
Residents of Alaverdi, a city situated in the northeast of the Armenian province of Lori, complain that the tap water smells extremely unpleasant and musty and has strange colour.
However, the relevant authorities state that the routine laboratory tests used in water-quality surveillance and quality control have not detected changes in water quality.
"What is the cause?" say the residents.
