Abstract
Effective microorganisms (EM) technology was used to find the optimal method of water restoration in the designated experimental area. The study aimed to evaluate the impact of EM biopreparation on selected physicochemical and microbiological properties using ISO methods. A week after the application of biopreparations, a slight decrease in the nitrates content (0.375–0.531 mg L−1) and a significant decrease in the content of phosphorus compounds (0.130–0.304 mg L−1) compared to the control date were observed. Moreover, on the second date, the decrease in most values of microbiological properties was noted. Two weeks after the application, in most cases, the values of water quality properties were shaped close to values obtained in the control date (before EM application). The EM effect was rather short-term, but optimization of application properties may prolong the effect and thus, include the EM technology among the best eco-friendly technologies used for freshwater ecosystem restoration.

Reservoirs play a large role in water retention
Who showed no effect of Effective microorganisms (EM) on pH values in reservoir water (Słoneczko reservoir, Poland)
These authors suggested that pH values on a stable level may positively impact the adaptation and development of microorganisms introduced from biopreparations
Summary
Reservoirs play a large role in water retention. There are about 100 retention reservoirs in Poland and Turawa is one of the largest. Turawa and other reservoirs were built to control the water flow, inland navigation, hydro-energy obtaining, and recreation [1,2]. Total storage capacity of Polish reservoirs is 106 m3 [3]. Turawa reservoir and its surroundings are of great natural interest. Within its 2125 ha area, two legally protected sites were established to protect birds and their habitats—“Natura 2000 Turawa Lake (PLB160004)” and “Stobrawsko–Turawskie Forest” [4]
