The database of water resources protection zones (OPVZ) was established at the T. G. Masaryk Water Research Institute, p.r.i., approximately in 2004. In the following years, a number of partial updates took place.
Past tests of nuclear weapons in the atmosphere, nuclear energy facilities and tritium of natural origin are main sources of tritium in the environment. Thanks to its presence in environment and its favourable properties, tritium is used as a radiotracer.
On March 21, 2018, a seminar on the assessment of surface water status for the period 2013–2015 was held at the Novotného lávka in Prague, under the auspices of the Waste Waters-Purity Waters Group. The event was organized by the Czech Science and Technology Water Management Company.
This article deals with new Czech Standard 75 7221 Water quality – Classification of surface water quality  and replaces the previous 19 years old standard . It was necessary to take into account actual demands of the surface water protection from two points of view: pollution indicator selection and current environmental quality standards. The range of pollution indicators and limit values of water classification were revised.
The aim of this study is a summary of problems dealing with microbial pollution of flowing surface waters in the Czech Republic. Limits of counts of indicator microorganisms in current legislation and technical standards are presented, together with characteristics of the mostly used indicators of faecal pollution and methods of their detection.
Development of selected radionuclides in surface water in the vicinity of the Temelín Nuclear Power Plant in the period 1990–2016
The paper presents results and interpretation of long-term monitoring of occurrence and behaviour of radioisotopes 3H, 90Sr and 137Cs in surface water in the vicinity of the Temelín Nuclear Power Plant. 3H, 90Sr and 137Cs originate predominantly from residual contamination due to atmospheric nuclear weapons tests and the Chernobyl disaster in the last century.
The article describes hydrological and hydrogeological conditions in a small part of the Lišanský stream catchment near Rakovník. Natural conditions of this area have been influenced by human activity from the 15th century.
Cooperation of Water Research Institute and Povodí companies, state enterprise within the framework of radiation monitoring network of the Czech Republic
The paper sums up the legislative framework and cooperation of TGM Water Research Institute and Povodí companies, state enterprises.
The current situation in the field of water resources protection zones in the Czech Republic is problematic for a long time, not only in terms of their definition, but also the correct setting measures or data availability to the public.
Interview with Ing. Daniel Pokorný Director of the Department of State Administration of Water Management and River Basin Management at the Ministry of Agriculture
Interview with Ing. Daniel Pokorný Director of the State Administration of Water Management and River Basin Management at the Ministry of Agriculture on the topic of surface water and flood protection hydraulic structures.
On 20. 12. 2016 was held seminar Protective zones of drinking water sources from surface sources in the House of technicians in Prague.
Almost the entire 2015 precipitation was below normal and on the contrary temperature significantly above normal. Precipitation deficit began to show early in 2015 and peaked in mid-August with a further deepening in the autumn months.
In the last issue of the journal VTEI (5/2016), the reader can get acquainted with the opinion of SOVAK ČR to support “as soon as possible a complete ban on the use of glyphosate,” with regard to the possible contamination of surface waters with this substance (the main ingredient of total herbicides Roundup type) and its residues.
Although the European Commission on 29 June this year decided on a temporary extension of the use of chemical products containing the herbicide glyphosate for 18 months, the Association of Water Supply and Sewerage Czech Republic, IB (SOVAK) and the European Association of water companies (EUREAU) are pushing as soon as possible complete a ban on glyphosate.
The research team, consisting of experts from the TGM Water Research Institute, p. r. i. (RNDr. Dana Baudišová, Ph.D., Ing. Tomáš Mičaník, Ing. Eduard Hanslík, Ph.D., Mgr. Denisa Němejcová and others), started from February 2016 work on the research project “The quality and evaluation of surface waters”.
Recently, the Czech Republic has been affected with negative impacts of hydrological extremes (such as floods and droughts). This is the reason why different types of regulation modifications have been discussed in order to address increasing water scarcity and variability throughout a year.
Temporal and spatial changes in concentrations of selected radionuclides (tritium, radiostrontium and radiocaesium) were assessed in the parts of the Vltava and Elbe river basins affected by the operation of the Temelín Nuclear Power Plant.
Basic hydrological data are provided for any profile of the river network and serves as a basis eg. for the issue water management decisions, etc.
