The research has been carried out to check the mutagenic activity of the drinking water of the western region of Ukraine. It has revealed that the water from the artesian wells has good quality and does not show any mutagenic effects. Chlorination of water to disinfect it leads to the formation of mutagenic combinations which are capable of causing genetic as well as chromosome mutations and of causing recombinational effects. In the process of going through the technological chain mutagenicity decreases. Drinking water from the surface reservoirs is polluted to a considerable extent by mutagenic chemical compounds especially by organic combinations. Using chlorine as the disinfecting substance leads to the formation of chlororganic combinations in drinking water which can induct chromosome abberation in meristic cells of Allium cepa. The research has been carried out to reveal the possibility of using natural mineral glauconite to improve the quality of drinking water. The results which have been obtained testify that glauconite is capable of utilising mutagenic effects due to their absorbtive properties.
Key words: mutagenicity, drinking water, genotoxicology, chromosome abberations, gene mutations.
