Hazardous substances and their effects on drinking water sources

Abstract

Drinking water cannot be produced from every raw surface or groundwater in the European Union countries. The source must meet the set criteria for the raw water quaility. At present time, drinking water sources meet these requirements. However in the climate change period, accompanied in particular by long-term loss of water volumes, the set limit values for individual categories of raw water may be frequently exceeded. Human society must be prepared for this threat and take legislative and technical-operational steps in a timely manner to eliminate the risk This paper deals with the issue in the basic scope and declares what producers and steps can be used in practice to increase the resilience of water resources to the expected change in the water quality.
