Somatic coliphages are a new indicator for monitoring the efficiency of water treatment and purification in the Directive (EU) 2020/2184 of the European Parliament and of the Council of 16 December 2020 on the quality of water intended for human consumption and in Regulation (EU) 2020/741 of the European Parliament and of the Council from 25 May 2020 on minimum requirements for water reuse.
The aim of this contribution is the presentation of partial results of testing tertiary technology for recycling of treated urban wastewater. The obtain water will be used for watering of greenery, playgrounds, or for street cleaning. The quality of the treated water depends on the purpose of the use.
A proposal for a complete amendment to Directive 98/83/EC on the quality of water intended for human consumption was approved in February 2020. The new Directive came into force after all official procedures on 16 December 2020.
It is shown in the article, how the revision of the Czech methodical standard for abioseston analysis in water ČSN 75 7713 from December 2015 and the lowering of the limit value for abioseston in the Decree No. 252/2004 Coll. (drinking water quality) from 10 to 5% influenced results of routine laboratories.
Enterococci, together with representatives of the species Escherichia coli, belong to the so-called indicators of faecal pollution, which are used in the evaluation of the microbiological quality of bathing waters. Their determination is governed by the Decree of the Ministry of Health No. 238/2011 Coll. and performed by culture on selective agar media.
The Ministry of Health in cooperation with other related bodies compiles, on an annual basis, the List of outdoor bathing sites on surface waters where the bathing service is offered by the operator, and other surface waters used for bathing. It is compiled based on the long-term monitoring, performed, exclusively as in-situ measurements, by the regional hygiene stations. With respect to the fact that this way of monitoring is not only time-consuming but also financially demanding, the need for minimizing these expenses naturally arises.
Microorganisms are a very important and admirable part of the living nature system. Their importance is associated mainly with the impact on human health, ie with medical microbiology. On the topic of an interview with microbiology microbiologist RNDr. Dana Baudišová, Ph.D.
Monitoring of the coronavirus SARS-CoV-2 in wastewater – what the monitoring has shown us so far and where it is headed
Since April 2020, the presence of the coronavirus SARS-CoV-2 in wastewater has been monitored at TGM WRI, p.r.i. The method of detection is similar to that of clinical samples, ie the presence of a specific fragment of viral RNA is detected by PCR.
