In September, mercury levels in several water samples from the village of Tsav in Syunik Province exceeded the permitted limit, prompting authorities to urge residents not to use the water even for domestic purposes. A month and a half later, the Ministry of Health announced that, according to new tests conducted in Armenia and abroad, mercury levels were now within the permitted limits and the water was safe to drink.
However, several questions remain unanswered. Neither the exact mercury concentrations in the samples collected in September nor the numerical results of the new tests have been made public.
How much mercury was in Tsav’s water, how much is there now, what changed over the past month and a half, and has the source of the contamination been identified? The answers are important for understanding the basis on which specialists changed their recommendations regarding water use.
When it comes to drinking water safety, a statement that levels no longer exceed the permitted limit does not provide the full picture. Residents need to understand not only whether the water is safe to drink now, but also the level of contamination previously detected and the data supporting the new conclusions.
Publishing the exact mercury concentrations would make it possible to compare the September measurements with the latest results, while identifying the source of the contamination would help establish whether the problem has been resolved or its cause remains. Without this information, it is difficult to assess the extent of the change. The Ministry of Health’s announcement sets out its current position on water use, but full measurement data are also necessary to maintain public trust.
