The aim of the present study was to analyze changes in water consumption which took place in the years 2011–2020 in the Educational-Museum Center of Poleski National Park (Poland), from which wastewater is discharged to a hybrid constructed wetland wastewater treatment plant. Water consumption was shown to be dependent on the number of visitors to the museum. As the number of visitors grew from 11,000 in 2011 to over 55,000 in 2019, the annual water consumption increased from 131 to 430 m3. Along with an increase in the percentage of individual visitors in the total number of visitors to the museum from over 40% in 2011–2017 to over 80% in 2020, water consumption per person decreased from 12.21 dm3∙d-1 to 7.18 dm3∙d-1. The average daily water consumption per one visitor in 2011–2020 was 10.4 dm3∙d-1, a value that was similar to the water consumption standard for museums (10 dm3∙d-1) set out in the Regulation of the Polish Minister of Infrastructure of 14 January 2002 on defining average water consumption standards. The average daily amount of water used in the museum building in the individual months of the year ranged from 0.12 to 1.28 m3/d. The highest average daily water consumption was recorded in the high tourist season (May–August), and the lowest in the low tourist season (January–April, September–December).

Artificial small water reservoirs existing over peatbogs of Łeczyńsko-Włodawskie Lakeland have high ecological value. Planktonic rotifer communities of the reservoirs are characterized by high species diversity, presence of rare species as well as high abundance of periphytic and benthic-periphytic forms. Low nutrients concentrations of studied reservoirs confirmed low total rotifers density, presence of indicatory species and high ratio of algaevorous to detritivorous species. The analysis of domination structure of planktonic rotifers showed very low stability of their community and high vulnerability for changes of habitat conditions.

Jednym z ciekawszych i mniej poznanych ekosystemów wodnych są różnego typu torfianki: węglanowe, humusowe i eutroficzne. Analiza wrotków planktonowych w siedmiu takich zbiornikach Pojezierza Łęczyńsko- Włodawskiego wykazała: dużą różnorodność gatunkową, obecność gatunków rzadkich, znaczny udział form peryfitonowych i bentosowo-peryfitonowych oraz duże różnice faunistyczne między wrotkami różnych torfianek. Mała liczebność wrotków, gatunki wskaźnikowe, znaczny udział gatunków roślinożernych w stosunku do detrytusożernych wskazują na małą żyzności większości torfianek. Mimo tych cech analiza struktury dominacji wykazała brak zrównoważenia zgrupowań wrotków i możliwość ich małej stabilności w przypadku jakichkolwiek zmian środowiskowych.
