The study of water quality in springs and wells in Křivoklátsko area.
Brabenec, Tomáš ; Benešová, Libuše (advisor) ; Popovský, Jiří (referee)
At present, the nature around us is constantly being polluted by anthropogenic activities; therefore the quality of all components of the environment, including water must be monitored. This thesis examines mainly the water quality in selected springs and wells in the Protected Landscape Area of Křivoklátsko. For individual wells is shown in what environment they are and even some history. Several locations were tipped off where water sampling was carried out, and in the laboratory the basic physico-chemical parameters were defined. In conclusion of this thesis, are the individual wells and springs included in water quality classes according to CSN 75 7221. It is shown that monitored parameters have exceeded limits and whether the water in a well and spring is drinking or not.

The effect of sampling point on hygienically significant water indicators in natural bathing establishment
Zelinková, Myra ; Benešová, Libuše (advisor) ; Popovský, Jiří (referee)
In this diploma thesis, I deal with the influence of the sampling site on water quality in natural bathing lakes (Hostivar reservoir, Seberak pond and Vyzlovka pond) in this. I have established that hygienically significant kinds of phytoplankton may differ in terms of water quality especially where there are cyanobacteria constituting water bloom. Surface water bloom may be moved by wind to the lee side of the water body (Microcystis sp.). Aphanizomenon flos-aquae water bloom floating in water column can be affected by wind and by water flow (which may be partly affected by wind as well). With the prevailing fibrous Planktothrix agardhii which does not connstitute water bloom the concentration of chlorophyll-a and cyanobacterial cell abundance in individual sampling sites are similar although the concentration of chlorophyll-a a is about 200 g.l-1 . Microcystis sp. and Scenedesmus sp. survive under eutrophic conditions in competition. From the microbiological perspective, water quality can differ within a single sampling site in places at a distance of less than 100 m. Microbial contamination can be caused by bathers, water birds, farm animals and probably by the removing of microorganisms from sand, mud and sediments on the beach or shore. Rain episodes probably increase the abundance of E.coli...
