Effects of drought on environmental health risk posed by groundwater contamination.

This publication presents a comparison of the content of pollutants in groundwater samples taken at 117 measurement points in four regions of Poland during a drought period and in the reference period without drought. Based on the chemical analyses of water, an assessment of the health risk resulting from the use of underground water for consumption was carried out. The study aimed to determine whether drought affects the increase in health risk exposure of the population.

Environmental health risk posed by contamination of the individual water wells.

This paper presents the results of analyzes of water samples taken from individual water wells intended for supplying households in non-urbanized areas with low population and infrastructure density. Relatively high concentrations of harmful pollutants were found in ground waters of the examined spots located in the suburban areas which may increase the risk of health incidents in exposed populations. Based on long-term measurements carried out in individual spots and toxicological data, the individual health risks related to carcinogenic effects in humans were assessed, resulting from direct ingestion of such water and from dermal contact.
