The potential vulnerability of the Chernivtsi water supply systems is analyzed in light of some basic shortcomings committed in the general planning, the poor realization of the project and some natural conditions imposing potential threats. Also the potential threat of intentional and unintentional human malicious activity is evaluated. Two potential strategies of mitigation are considered: the deep restructuration of the water supply system and some minor targeted steps aimed at the minimization of the threats. The latter option requires a smaller investment and promises quite reliable results in the short-term prospect.
