B. Mineral water.
The first time water of Bankya was studied in 1891 by
A. Najdenovich, later on – in 1906 by Kr. Rusev, in 1939
by A. Azmanov, in 1953 and 1956 –by Kusitaseva and J. Melamed.
Mineral water in Bankya is clear, transparent, very tasty,
without smell, homothermal (36,5 C) and alcaline (pH>9). Radioactivity
is low-1,5 eman per liter, as measured by prof. Penchev in 1911.
Tabl .2. Physico-chemical values of Bankya mineral water
(as measured at 31.3.1953 –Kochankov, 1972 and at 1983 by D.
Konstantinova).
