Opis:: One of the most frequently implemented processes in the water treatment technology is filtration through a biosorption bed. The techniques based on biochemical processes involving bacteria result in obtaining high quality of water. There are a number of different materials used as the filler material for biological filters. Carbon deposits are the most popular, due to their high effectiveness. The problem with the use of this process is the leaching of microorganisms from the biofilm and the biological stability of water thus obtained. There is a need to develop quick methods to assess the microbiological quality of this water. Modern techniques for determining the amount of microorganisms, such as flow cytometry and luminometry may be the right tools. The water collected for testing came from the Water Treatment Station located in the Podkarpackie voivodeship. The microbiological tests carried out in the analyzed water samples collected after the filtration process on granular activated carbon. Both traditional culture method and modern techniques used to determine the number of microorganisms (flow cytometry, luminometric ATP assay) demonstrated an increase in the number of microorganisms in the examined waters (in the water after the filtration process and in the water introduced into the water supply network) after the incubation process for 3 and 7 days at 15 and 22°C.

Opis:: Growing areas of sealed surfaces, rising water needs due to industry development, increasing populations, and climatic changes affect precipitation patterns and form a vision of the future in which meteoric water storage may become almost an obligatory activity. The aim of this paper was to identify the amounts and, to some degree, the quality of microorganisms present in rainwater collected from different types of rooftops of utility buildings in the spring-summer season. Apart from the classic culture plate method complemented by flow cytometry. The results of performed analyses explicitly show that rainwater collected from rooftops and directly from air prove to be microbially contaminated to a substantial degree, which includes pathogenic coliforms and faecal streptococci. Waters collected after dry periods also contained bacteria like Clostridium perfingens. The findings rule out the possibility of using rainwater collected from roof surfaces of utility buildings before its treatment.

Opis:: This paper presents the results of research on the bacteriological quality of rainwater collected directly from precipitation and various roof surfaces – concrete and ceramic roof tiles, galvanised sheet and a terrace covered with epoxy resin. Samples for the research were collected in a suburban area in 2015-2016. The quality of rainwater was assessed based on the results of bacteriological analyses (the presence of indicator bacteria and the total mesophilic and psychrophilic bacteria count). The effect of the seasons and the type of roofing on the microorganism count was discussed. Significant differences in the quality of rainwater collected from various roof surfaces, related to the roughness and chemical composition of the materials covering the roofs were indicated. In the rainwater examined, significant numbers of potentially pathogenic microorganisms such as Escherichia coli, coliforms and faecal streptococci were detected. The results obtained were the basis for indicating the possibility of using rainwater for various household purposes. Rainwater is not suitable for uses requiring the quality of water intended for consumption due to a great number of psychrophilic, mesophilic and faecal bacteria.

Opis:: Najbardziej czułą metodą wykrywania skażenia wody wodociągowej jest badanie mikrobiologiczne. Bezpieczeństwo wód pod względem mikrobiologicznym jest oceniane głównie na podstawie wyników tradycyjnych badań hodowlanych, umożliwiających wzrost kolonii bakterii na podłożach odżywczych. W ostatnich latach zastosowanie w mikrobiologii znalazła nowoczesna technika cytometrii przepływowej. Diagnostyczna metoda oparta na cytometrii przepływu jest znacznie szybsza, a także bardziej wszechstronna. Badania jakości mikrobiologicznej wody wodociagowej prowadzono w rejonach powiatu rzeszowskiego, tj. w rejonie systemu wodociągowego zasilanego z ujęcia wód powierzchniowych oraz w rejonie małych systemów wodociągowych zasilanych z ujęć wód podziemnych. Zakres analizy mikrobiologicznej jakości wody wodociągowej opierał się na oznaczeniu wybranych wskaźników stanu sanitarnego wody tj; ogólnej liczby bakterii psychrofilnych i mezofilnych na agarze odżywczym (referencyjnym) zwanym Agarem A oraz dodatkowo na agarze wzbogaconym zwanym Agarem R, liczby bakterii grupy coli oraz paciorkowców kałowych. Oznaczenie ogólnej liczby mikroorganizmów metodą cytometrii przepływowej wykonywano z zastosowaniem dwóch barwników Sybr Green oraz jodku propidyny. Woda z ujęć wód podziemnych, nie będących pod stała kontrolą mikrobiologiczną posiadała gorsze parametry mikrobiologiczne. Stosowane nowe metody oznaczeń mikrobiologicznych wykazywały większe ilości zanieczyszczeń mikrobiologicznych.
The most sensitive method of detecting contamination in water supply networks is microbiological testing. Microbiological water safety is evaluated mainly based on the results of traditional tests that rely on bacteria culturing on the so called bacterial growth mediums. Flow cytometry is a modern technology that has been used in microbiology only recently. The diagnostic method based on flow cytometry is much faster and more versatile. Microbiological quality testing was conducted in rzeszowski district, in the area of water network supplied by surface waters, and in the area of water network supplied by underground waters. The scope of the analysis of the microbiological quality of tap water was based on the determination of selected indicators of the sanitary condition of water ie; the total number of psychrophilic and mesophilic bacteria on nutrient agar (reference) called Agar A and additionally called agar supplemented with R, the number of coliforms and faecal streptococci. Determination of the total number of microorganisms by flow cytometry was performed using two dyes SYBR Green and iodide pyridine. Water from underground water intakes, not under the permanent control of microbial had worse microbiological parameters. Used new methods of microbiological assays showed greater amounts of microbiological contamination.

Opis:: There is a need to search for additional indicators allowing for more accurate identification of both the trophic status of waters as well as its chemical and biological consequences. The work detailed in this paper involved a preliminary analysis pertaining to the possibility of using an isotopic index in association with the values for trophic and saprobic indicators in describing a dam reservoir experiencing a far-reaching eutrophication. The water samples for the physicochemical analysis were collected from three sites along the axis of the dam reservoir in Rzeszów three times during the spring and summer of 2013. The results sustained the classification of the Reservoir's waters as hypertrophic, irrespective of the particular zone sampled. While phytoplankton blooms characterised by reference to the numbers of organisms per unit volume of water were also similar throughout the Reservoir, diversification in terms of taxonomic composition was to be noted, given the occurrence of cyanobacteria among the dominant diatoms in the area close to the dam. This presence was accompanied by enrichment of the Reservoir's suspended organic matter with carbon of the heavier ¹³C isotope. On this basis, the δ¹³C isotopic index can be regarded as a potentially useful indicator allowing for more accurate identification of both the level and the nature of the ongoing trophic degradation in bodies of water.
