“…Usually this method involves supplying the hypolimnion with compressed air or oxygenated water from the surface, leading to thermal destratification of the water column [2]. The effectiveness of water aeration is well documented due to numerous applications of these methods in eutrophied lake ecosystems [3][4][5][6][7][8]. However, the negative result of such water mixing is moving the nutrient-rich hypolimnetic waters up to the surface, which stimulates primary production [1].…”

Abstract:Groundwater intake near Lake Głębokie, situated in the city of Szczecin in Northwestern Poland, resulted in a distinct decrease in the lake water level. Water intake from a river and a neighboring urban area led to eutrophication and a strong cyanobacterial water bloom. Both the water intake and recreation were threatened due to the possible influence of cyanobacterial toxins. The lake was subjected to three sustainable restoration methods: aeration of sediment-water; iron addition to precipitate P, and; biomanipulation. The goal of our study was to determine the changes in the taxonomic composition of phytoplankton and chemical water variables during restoration measures. A comparison of the data obtained during this research with the pre-restoration data showed that, as a result of the treatments orthophosphates decreased, rarely exceeding 0.06 mg P·L −1 , and cyanobacterial water blooms disappeared. Cyanobacteria were found in the lake but they were not abundant. Chrysophytes and diatoms were the most abundant in springtime of each year. Green algae, desmids and chrysophytes were particularly abundant in summer, while cryptophytes predominated in autumn. Algae from all these groups do not pose a threat to either recreation or water intake. The deep chlorophyll maximum occurring in summer at a depth of 5 m as a result of restoration confirms the lower trophic status of the lake, alluding to mesotrophic conditions.

Have studied lake close to neutral pH 7.70 to 7.74. All lakes in accordance with the classification of the European Union Water Framework Directive have been included in the first class. Studies have shown a diverse water quality in lakes in relation to tested indicators. By analyzing the average annual values can be noted that the pH of the water, the O 2diss and the concentration of NH 4 + , NO 2ˉ, NO 3ˉ, PO 4 3-diss showed a relatively small variation in all investigated Lakes. The level of the total suspended solids in Starzyc lake the peasant was on level II class. The concentration in the surface layer of P tot . Lake is little differentiated, is at level II and III quality class according to the classification of the European Union Water Framework Directive. In the case of nitrogen-compounds nitrates and nitrites values for these indicators were at level I and II class in all the surveyed lakes in accordance with the classification of the European Union Water Framework Directive. In 2008 attendance related macrofauna test bed showed that the most common they were mud-eating and larvae chironomids, oligochaeta (F = 100 %), which consisted of Tischlera classification of the species is absolutely solid. Among larvae of Chironomidae the species is absolutely integral were Chironomus f. l. plumosus (F = 100 %). However Chaoborus sp. belong to the accesoric species. Other designated species of fauna were accidental species of benthic (F) = 25 %. In 2009 attendance related macrofauna test bed showed that the most common they were mud-eating and larvae chironomids, oligochaeta (F = 100 %), which consisted of Tischlera classification of the species is absolutely solid. Among larvae of Chironomidae the species is absolutely integral were Chironomus f. l. plumosus (F = 100 %). However Asellus aquaticus Racov. and Chaoborus sp. belong to the accesoric species. Other designated species of fauna were accidental species of benthic (F) = 25 %. Fauna of the Starzyc Lake bottom during summer stagnation was poor in terms of quality, which proves its considerable biological degradation. In terms of the concentration in the test macrozoobenthos Lake dominated and Oligochaeta, Diptera larvae.

“…Urbanization is the cause of many changes which is taking place in the environment, including those found in the catchment [3][4][5][6][7][8][9]12,15,16,19,21,23,25]. To address the increasing degradation of the surface waters in the European Union, changed the approach to the evaluation and protection of water resources.…”

The work shows the evaluation of physico-chemical parameters of water Resko lake, based on the European Union Water Framework Directive. Research was carried out in the years [2008][2009], in the period from April to October. With each of the three measuring stations on the tested water samples were taken two separate Lakes for chemical analysis. At the place of sampling were numbered pH. Trying to test water were taken by Polish Standards. Collected water samples were fixed in accordance with the recommendations in the Polish Standards. Other indicators for the quality of the waters have been tagged within 24 hours from the moment of download attempts. Have studied lake close to neutral pH -7.63 to 7.79. All lakes in accordance with the classification of the European Union Water Framework Directive have been included in the first class. Studies have shown a diverse water quality in lakes in relation to tested indicators. By analyzing the average annual values can be noted that the pH of the water, the O 2diss and the concentration of NO 3ˉ showed a relatively small variation in all investigated Lakes. The level of the General Suspension in Resko lake the peasant was on level II class. The concentration in the surface layer of Ptot. Lake is little differentiated, is at level II quality class according to the classification of the European Union Water Framework Directive. The concentration of total phosphorus is 0,22-0,29 mg⋅dm -3 .
