Dynamics of micropollutant loads into water supply reservoirs Vír I, Opatovice and Ludkovice

Pesticides are still an important group of substances involved in surface water pollution. Their increased occurrence in watercourses in the agricultural landscape is mainly linked to rainfall-runoff conditions, types of cultivated crops, and methods of agricultural management. In order to capture these factors, passive sampling techniques were chosen for the assessment of the load of these substances in selected catchments of water supply reservoirs in the administration of Povodí Moravy State Enterprise. These techniques consist of continuous exposure for several weeks with gradual (integrative) capture of pollution on suitable sorbents. The POCIS (polar organic chemical integrative samplers) were chosen in this work – widely used samplers suitable for capturing polar organic substances. They were applied in eight consecutive sampling campaigns to cover the entire growing season.

Atmospheric deposition as a possible source of surface water pollution (Preliminary results of the project, part 1 – heavy metals)

Concentrations of selected heavy metals in collected atmospheric precipitation
and surface water were monitored at pilot sites in the Jizera Mountains, the Moravian‑Silesian
Beskydy Mountains and the Bohemian‑Moravian Uplands (CZ) over the course of one year to determine the significance of the impact of precipitation on surface water quality in an otherwise relatively low anthropogenically influenced environment. The measurements show that for some
metals, atmospheric deposition in heavily loaded areas can cause significant inputs to streams and reservoirs, but the resulting balance is strongly influenced by the environment and its past loading.

Space-time dynamic of pesticide loading in the drinking water reservoir Švihov

The article deals with space-time dynamic of non-polar and polar compounds load into the drinking water reservoir Švihov in Želivka river basin during the whole vegetation season by passive sampling techniques. The monitoring on the nine tributaries of the Švihov water reservoir and on the raw water inlet to the Želivka drinking water treatment plant took place for eight months from April to November 2018.
