The article aims to analyse the impact of military operations on the hydro-ecological state of water bodies in Ukraine, analyse potential military risks and assess the prospects for recovery in the water sector. The war leads to the destruction of water supply infrastructure and, secondly, to the pollution of natural waters with sewage and ammunition. Thus, Ukraine's hydro-ecological condition of natural watercourses and reservoirs is deteriorating during a full-scale war. First, we analysed the literature and modern scientific publications and studied the current state of the water bodies of Ukraine under martial law. The article analyses the key consequences of military operations on water bodies, including the destruction of water infrastructure and hydraulic structures, contamination by explosives and destroyed military equipment, flooding by mine water, and leaks from tailing ponds. Special attention is paid to the results of water quality monitoring in wartime. The authors systematised and reviewed the key incidents of destruction and damage to hydraulic structures since the beginning of the war. Potential risks to water bodies in the context of Russian aggression are studied. Finally, the author analyses the directions of the post-war reconstruction of Ukraine and proposes a list of practical steps necessary to restore water resources. The author's view on post-war reconstruction measures in water resources is offered. In addition, environmental organisations and local authorities can use the results of this scientific research.

The article presents the principles of sustainable development in relation to protecting natural waters against pollution. It also presents the development of water supply and sewage networks in rural areas in Poland over the years 1989-2015. Increased rate of constructing sewage disposal systems has been demonstrated, which occurred thanks to obtaining EU funds. It was found that the problem of wastewater management in rural areas with dispersed buildings is mainly tackled by the use of individual on-site devices. Based on the analysis of sewage test results, the author assessed the efficiency of selected household sewage treatment plants based on various technologies of operation. Using the analysis of sanitary state of Commune of Lubiewo in years 2012 to 2016 as an example, delay in building of a sewage system in the rural areas and increase in number of private sewage purification equipment were exposed.

Podano definicje cyberterroryzmu i wyjaśniono specyfikę cyberataków pasywnych oraz aktywnych. Zamieszczono opis trzech cyberataków, ukierunkowanych na infrastrukturę wodociągową. Zestawiono metody nielegalnego zdobywania danych oraz zakłócania pracy systemów informatycznych. Wymieniono najczęstsze błędy, zagrażające bezpieczeństwu przechowywanych danych. Omówiono włoskie doświadczenie, mające na celu wskazanie konieczności zabezpieczenia infrastruktury wodociągowej przed cyberatakami.

The paper presents the definitions of cyberterrorism. In addition, the character of passive and active use of IT information or networks to support or play an attack has been clarified. 3 examples of cyber-attacks on water infrastructure have been described. The illegal methods of data obtaining and disruption of the IT systems work were presented. That was pointed to the most common security threats related to the access of an utility network data. The Italian research, which has aimed at protection for water infrastructure against cyber-attacks, was characterised.
