## History

Alma-Arasan mineral springs were discovered in 1931 on the slopes of the Passage River.

Five wells were drilled from 1951 to 1953 and their water production is 520 to 525 $m^3/d$ (137,000 to 139,000 US gal/d).

In November 2019, repair and renovation work was completed to improve the spring area. New stairs and a walkout playground were built. Three small swimming pools were installed. Two of them are filled with warm mineral water, one is from the river. A small house is used for swimming in the wintertime and protection from wind and rain.

## Description

According to the chemical composition water belongs to the sulfate-hydrocarbonate-sodium type. The water contains biologically active components (mg/L): silicon dioxide (40-75), fluorine (3.6-6), hydrogen sulfide (0.58), radon (9-13 eman).
