Abstract
Safe drinking water is one of the most important conditions for a healthy life. However, in case of disasters and emergencies, the water is often contaminated with various impurities of physical, chemical and/or biological origin. These contaminations can lead to a number of health problems, including various infectious diseases. For that reason, it is important to act preventively, and to perform appropriate treatment and water purification in a timely and urgent manner, depending on the type of pollution. In order to determine the type of pollution and perform the appropriate water treatment, the precondition is arranging certain chemical analyzes and monitoring of water quality through quality parameters. Since our time and economic resources are limited in the first moments of the accident, it is not possible to monitor all the parameters, so we monitor the most important: pH value, amount of residual chlorine, color, turbidity and the presence of pathogens. However, even when the type of pollution is determined, it is sometimes not possible to do centralized water purification immediately. Therefore, it is important to know the methods that can independently, and with the help of some handy tools, be applied in our household (eg. disinfection by boiling water or using some of the chemicals for disinfection; sedimentation, etc.). Using these methods, at least a physiological minimum can be provided for family members in the first moments after the accident, until a centralized purification is performed.
Highlights
Water is the source of life, a precious source of health and a necessary condition for human survival
The purpose of this article is to point out the importance of monitoring the quality of water after floods by the competent authorities, and to raise awareness of individuals that in situations where there is a possibility that water is polluted can take urgent measures in their household to purify water and make it usable for a drink
Since our work deals with monitoring the quality of water after floods, we will pay the most attention to disinfection as a method of purification
Summary
Water is the source of life, a precious source of health and a necessary condition for human survival. Where there is no water, there is no life.This is the first need of a man, which must be provided permanently.People use water for drinking, food preparation, maintaining hygiene, in agriculture, industry. It is the most abundant substance in the human body. As a basic means for human life and health, water has become one of the most interesting and most studied substances.Nowadays, the problem of providing sufficient amounts of water for human and other needs is given special attentiongreat mental and material efforts are invested. The amount of clean water is constantly decreasing, and it is consumed where it is necessary, and where it should not be consumed
