Risk assessment is a continuous process, which is why, based on the performed risk analysis, a proposal of corrective or repair actions that the water supply company should take in order to constantly control and reduce the risk was presented. Corrective actions are presented as follows for the sources of threats that have the most significant impact on the risk levels for intakes A–D: • Developing procedures for dealing with contaminants that conventional treatment will not be able to remove; • Obtaining funds from local government units for the construction of sanitary sewage systems in the towns located in the catchment area of rivers from which the water is drawn, in particular, in the indirect protection zone of the water intake; • Monitoring the usage of plant protection products in the indirect protection area and controlling their quality; • Developing a plan for checking the technical condition of facilities and pipelines at wastewater treatment plants and procedures in case of a major failure in wastewater treatment plants; • Banning new municipal and industrial wastewater treatment plants within the indi- rect protection zone of the water intake. 5. Conclusions and Perspectives In accordance with the provisions of the Drinking Water Directive [14], risk assess- ments and risk management in the catchment areas of water intakes should be carried out in the EU by 12 July 2027. Poland meets this requirement—it is estimated that risk analyses will be carried out by the end of 2022 for water intakes producing more than 10 m 3 of water per day or supplying water to more than 50 consumers. Some of the Polish water supply companies have already performed a risk analysis, submitted it to the relevant authorities (the voivode) and obtained a decision to establish a water intake protection zone. Actions aimed at minimizing the risk to water supply systems defined in Poland by the Water Law Act [10] are in line with the WHO recommendations. Figure 4.
