“…The total nitrogen, total phosphorus, and total aluminum contents tended to increase during PAC application, but the differences due to the PAC application were not significant. In this study, the reduction of phosphorus was around 32% after one week of treatment, which was similar to a study in Poland that observed a reduction of TP content (28%) at the bottom of Lake Klasztorne Małe [22].…”

Eutrophication and plankton blooms have long been the primary environmental concerns for freshwater ecosystems in Thailand and worldwide [1][2][3]. The main cause of the problem is the addition of excessive plant nutrients originating from various sources, such as agricultural areas, wastewater treatment plants, industrial sectors, and residential areas. These nutrients stimulate rapid growth of phytoplankton, especially cyanobacteria, which can lead to degradation of water quality. Eutrophication causes an unpleasant hue and odor of water bodies as well as the production of cyanotoxins by cyanobacteria, such as Microcystis, Planktothrix and Anabaena [4,5]. These biotoxins can cause acute and chronic health problems for humans and other living organisms exposed to contaminated water. These health effects include allergies, skin and eye

“…This should be performed to achieve an active barrier (i.e., capable of binding SRP in the water column and to cap bioavailable forms of P in the sediments) and for addressing possible external nutrient sources for which attenuation has not been performed. Additionally, this phosphorus inactivation method does not directly affect the content of organic phosphorus [78][79][80]. Any reduction in the phosphorus organic form is the result of reduced primary production in the water body.…”

Lake water has been impaired with nutrients due to the synergic action of human-made activities and climate change. This situation is increasing eutrophication around the globe faster than before, causing water degradation, loss of its uses, and water-associated economic and health effects. Following the Sustainable Development Goal 6, more precisely its target 6.6, nations are already behind schedule in protecting and restoring water-related ecosystems (i.e., rivers and lakes). As concerns with eutrophication are escalating, eutrophic water remediation practices are the keys for restoring those lake waters. Diverse methodologies have been investigated focusing on the nutrient that limit primary productivity (i.e., phosphorus), but few have been applied to in-lake eutrophic water remediation. Thus, the objective of this paper is to provide an overview and critical comments on approaches and practices for facing eutrophic lake water remediation. Information on the successful cases and possible challenges/difficulties in the peer-reviewed literature are presented. This should be useful for supporting further remediation project selection by the stakeholders involved. In summary, for a successful and durable restoration project, external nutrient inputs need to be managed, followed by holistic and region-specific methods to attenuate internal legacy nutrients that are continually released into the water column from the sediment. When aligned well with stakeholder participation and continuous monitoring, these tools are the keys to long-lasting water restoration.

The objects of this study were lakes Mielenko (LM) (7.8 ha, 1.9 m), Klasztorne Małe (LKM) (13.7 ha, 20.0 m), and Klasztorne Duże (LKD) (57.5 ha, 8.5 m), located in north Poland (Kashubian Lake District). These lakes received raw sanitary and storm wastewater, leading to extreme degradation of these water bodies. This study aimed to present changes in buffer indicators such as reaction, alkalinity, total hardness, and Ca and Mg content that occurred as an effect of their restoration using the sequential application of coagulants as an innovative approach to the phosphorus inactivation method. Sustainable phosphorus inactivation in the study lakes made it possible to achieve nutrient concentrations in the range of values typical for low-trophic lakes. A radical decrease in P concentration in the water resulted in a limitation of production processes. Moreover, after a, it was noticed that the water parameters determining its buffering properties did not show a clear vertical stratification with increasing values toward the bottom. For example, before restoration, the mean e value of alkalinity in LM fluctuated around 2.10 mval/L, and after restoration activities, the average value was 1.97 mval/L. In LKM, the mean alkalinity value in surface water layers was 2.53 mval/L, and in bottom water layers, it was 4.92 mval/L; after restoration treatments, the average alkalinity of surface water was 2.18 mval/L, and in bottom water, it was 2.99 mval/L. In the last LKD, under the influence of the applied restoration, the average alkalinity of surface waters changed from 2.21 to 2.07 mval/L, and in bottom water, it changed from 2.86 to 2.12 mval/L. The values of parameters determining the buffering properties of lake water after restoration activities allow their water to be classified as slightly or medium hard. The changes obtained can be considered beneficial because water that is too hard does not support the development of aquatic organisms, and the values obtained in the study lakes after sustainable restoration are optimal for the construction of plant walls, shells, and fish bones.
