Monitoring of Nitrate Content in Local Sources of Drinking Water in Eastern Bohemia

摘要

The aim of this work was to monitor the quality of drinking water taken from wells in the region of Eastern Bohemia. The parameter monitored was the nitrate content in water. The samples were repeatedly collected from 33 wells, and the nitrate content was determined by the method of simultaneous photometric neutralisation micro-titration. The results obtained show that the drinking water standard of nitrate content is met by only 60 % of the samples analysed. The relation between the nitrate content in water and the effect of surrounding agricultural activities, the position and, as the case may be, the depth of the wells was proved. Also observed were changes in the nitrate concentrations during various plant growing seasons.
