Are complex mixtures of xenobiotics common in groundwater?
Original language description
Although groundwater is considered a relatively safe water resource being naturally protected by soil and rock layers, xenobiotics also occur in groundwater contaminated by agriculture, industrial sites, landfills, leaky sewers, etc.. More than 200 man-made chemicals have been lately monitored in groundwater at almost 700 sites in the Czech Republic. The national groundwater monitoring network is set up the way that it does not monitor contaminated sites such as industrial areas, landfills, etc. In spite of such setup, 120 chemicals were found in groundwater in various mixtures, up to 30 substances occurred in individual monitoring sites. In total 2715 samples were taken in years 2016-2017, thereof 528 (20%) samples were free of such compounds, 323 (12%) samples contained just one compound, 231 (8%) samples contained 2 compounds, 3 to 10 compounds were detected in 1255 (46%) samples and more than 11 up to 30 compounds were found in 378 (14%) samples. Prevailing contaminants were pesticides followed by VOCs (mainly chlorinated hydrocarbons) and PAHs. Also, alkylphenols, pharmaceuticals, chelating agents, PCPs and benzotriazoles were detected in groundwater. The total concentration of xenobiotics in groundwater can exceed 100 and reach up to 551 μg/l. Monitoring results show that mixtures of various xenobiotics can be found in groundwater more often than one could suppose.
