The Monte Carlo procedure and a new method to determine the chirality of water environments and their classification were used for the first time to study the chiral properties of small water clusters such as (H$_2$O)$_n$, K$^+$(H$_2$O)$_m$, and Na$^+$(H$_2$O)$_m$ ($n = 4–8$, $m = 5–10$) at a temperature of 1 K. The probability that the studied water clusters will be chiral becomes higher at an increase in their size. It is revealed that a small water cluster devoid of impurities is not dominated by one of the arrangements (right or left). The addition of K$^+$ or Na$^+$ impurity ions does not change the equilibrium distribution of right and left configurations in the 10 000-sample set.
