The assessment of the status of surface water bodies in the Czech Republic for the period 2013–2015

This article aims to present to the general public the results of the assessment of the ecological status/potential and chemical status of surface water bodies categories “river“ and “lake“ for the period 2013 to 2015 in the Czech Republic. The assessment was carried out in 2017 by the Water Research Institute of T. G. Masaryk, p. r. i.

Environment quality of water elements of heritage protected areas

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.

The impact of oxygen and nitrates availability on phosphorus cycle in sediments – an example of the Vranov Reservoir

The inflow parts of eutrophic reservoirs typically exhibit exacerbated rates of primary production, with concomitant increase in organic matter sedimentation. Its microbial remineralization leads to the consumption of electron acceptors.

Information about ORAM

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.

Municipal wastewater as a diagnostic medium

The paper outlines the possibilities of using the epidemiological approach to the analysis of municipal wastewater to monitor the lifestyle of the population, its dietary habits, the environmental impacts on humans, the assessment of the state of health of the population and monitoring the consumption of illicit drugs and other substances in the monitored population

Classification of surface water quality

This article deals with new Czech Standard 75 7221 Water quality – Classification of surface water quality [1] and replaces the previous 19 years old standard [2]. 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.

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.

Water sampling specialist and requirements for his professional competence

Testing laboratory is responsible for the sampling for the purposes of the Water Act, the Water Supply and Sewerage Act and the Public Health Protection Act. Requirements for the qualification and further training of samplers are defined by the laboratory in its controlled documentation, while in the case of water sampling; the new minimum requirements are set in the standard ČSN EN ISO 5667-14.

The importance of catchment characteristics in terms of intensive erosion runoff formation threat level

We located almost 130 000 critical localities near to urban areas where eroded material can enter the urban area. These localities were divided into five threat categories. Detailed modelling by WaTEM/SEDEM provided an extensive database of almost 130 000 micro catchments with outlet profiles threatened by intensive erosion runoff, and classified by five categories of threat for infrastructure damages.

Use of wastewater­‑based epidemiology for monitoring of illicit drugs consumption in Czech and international context

This paper presents a brief summary of information about the project Determination of the amount of illicit drugs and their metabolites in municipal wastewater – new tool for obtaining of complementary data on illicit drug consumption in the Czech Republic and about the 2nd International Conference on “Wastewater‑based drug epidemiology“, which was held from 11.–15. 10. 2015 in Ascona, Switzerland.

Water quality in drinking water reservoir Švihov on Želivka river and its river basin, with focus on specific organic compounds

River basin of the largest drinking water reservoir Švihov on the Želivka River is distinctly anthropogenically affected both by direct human activities and also by the agriculture. The quality of the surface water is endangered in long-term period mainly by the eutrophication, pesticides pollution and erosion.

Assessment of the relationship between water quality and functions of small water reservoirs

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.
