The relationship between economic development and stream water quality in the Czech Republic between 1975 and 2019 was assessed based on an Environmental Kuznets Curve (EKC) model using two main organic pollution indicators: Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD).
Water quality monitoring has a much shorter history in the Czech Republic (CR) than water quantity monitoring. Yet the quality of water resources is crucial for society, industry and agriculture.
Interview with RNDr. Marek Liška, Ph.D., Head of the Laboratory Department of the Vltava River Basin on the topic of water quality, micropollutants and other interesting points.
Fidings from testing of selected biochemical products to the heritage sites water elements environment adjustment
The article is focus on the presentation of knowledge from testing of selected biochemical preparations for the treatment of the environment of water elements of historical gardens and parks and cultural monuments.
Interview with RNDr. Eva Kočková, a long-time employee of T. G. Masaryk Water Research Institute in the field of hydrochemistry and evaluation of water quality
“Water” as an irreplaceable natural source of life has accompanied you throughout your professional career, which you started right after graduating in 1954 at the Masaryk University in Brno in organic chemistry…

Souhrn Náhled do historie ukázal, že rekreace u vody, jako záliba k trávení volného času, byla odedávna rozšířena i v Praze, kde byly velmi oblíbené, dnes již zaniklé, říční plovárny. Na historický průzkum navázal v projektu „Možnosti vodní rekreace na území… Read more »
Water quality of the Prague’s streams. Part 2: tributaries to the Šeberák pond and to the Hostivař reservoir
The possibility of a recreational use of some of the Prague reservoirs is limited mainly by the quality of the tributaries. The article follows the previous one and sums up the results of the water quality monitoring in selected profiles of the tributaries of the Šeberák pond (the Vestecký and the Kunratický streams) and of the Hostivař dam (the Botič and the Pitkovický streams) during 2018.
Results of water quality observation in the selected profiles on the Motolský and Litovický streams during the year 2018 are presented. Monitoring of water quality parameters was focused mainly on the nutrients content (nitrogen and phosphorus), chlorophyll-a concentrations and on the phytoplankton and zooplankton species composition.
High eutrophication is the main factor that has recently disabled the Jordán water reservoir for water supply and recreational purposes. Large-scale dredging of sediments was done between years 2011 and 2014. Thereafter a complex monitoring of water quality has been initiated since 2015.
In this article, water quality and the assessment of anthropogenic pollution in sediments of the middle course of the Elbe River oxbow lakes Kozelská and Vrť were studied. It is widely accepted that the oxbow lakes are extremely significant ecosystems. However, a large amount of contaminated material may deposit in these lakes. The research of lake Kozelská was chosen especially to its proximity to the chemical factory Spolana in Neratovice, which used to be the biggest source of pollution of the Elbe River.
Water elements represent a significant part of the environment of cultural heritage sites, conservation zones and areas. To fulfil the required functions, which may include social, historical, recreational and educational, but also environmental functions; it is necessary to ensure their corresponding target state.
Odra River Alarm Modul (ORAM) will be part of the NAVAROSO project. There are no results of tracer studies of the Czech part of the Odra River in the last twenty years. That´s the reason, why tracer experiment data of the Svitava River were used for analysis.
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 article presents the results of the project aimed at improving the situation in the catchment area of the Mostiště water reservoir where good water status is not achieved because of the high water load of nutrients.
Policy of Protection from impacts of drought and water scarcity in the Czech Republic – consultation and processing
In the context of a severe drought period, which has started in 2014, an inter-ministerial commission WATER-DROUGHT was established to prepare a strategic policy document on protection from impacts of drought and water scarcity in the Czech Republic.
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.
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”.
Czech Republic is among six countries in the EU, which shows in microbiological and chemical parameters of drinking water from 99 to 100 percent of the required quality.
The paper summarizes the „Methodology for comprehensive management of small water resources to ensure optimal quality of drinking water in normal and emergency situations“ that is a main result of the research project supported by the Technology Agency of the Czech Republic (TA 02020184).
Many professionals deal with water quality monitoring in the Czech Republic with various goals and various quality of gathered information. The Czech Hydrometeorological Institute (CHMI) has built and developed a unified longterm monitoring system providing comparable high quality data at a nation- al scale.
Small water reservoirs are one of the principal elements of agricultural landscape in the Central European context. The monitoring of the quality of aquatic environment of selected ponds and small reservoirs (SWR) in areas of southern and central Moravia and the Vysočina Region was carried out in 2013 to 2015.
Ecology determined the dilution factors for the KB Alloys facility over ten years ago. The development document record is not clear as to the method used to determine the values. Ecology made an attempt to model the conditions using CORMIX 6.
