“…Lake Mariut (LM) is an inland closed shallow lake Mean depth of 1 m) lies south of Alexandria City. It is a depression extends for about 20 km between 31° 0148˝ and 31° 10́ 30˝ N and 29° 4948˝ and 29° 5700˝ E. Its bottom is below the sea level by values ranging between 4.0 and 3.4 m and separated from the neighboring Mediterranean Sea by a ridge called Abuser (Shaaban et al 2021). The lake as mentioned formed from four basins, the main basin MB, (the recently restored basin), North-West Basin (NWB), South-West Basin (SWB), and Fishery Basin (FB).…”

“…This lake since the late sixties of the last century and along 50 years ahead, was a victim of uncontrolled urbanization (El-Rayis and Abdallah 2006; El Kafrawy et al 2017), and its water quality showed a downward trend that accompanied by a remarkable decline in its importance as a source for the popular Tilapia sh for the Egyptian people and as a place for recreation and nesting wild birds (El Kafrawy and Ahmed 2020). Where it was converted from the most productive and fertile aquatic habitat in the 1960s (produced about 60% of the total sh production from the coastal lakes) to the most polluted one and least productive in the 1990s (El-Rayis et al, 1997; Abaza et al, 2009;Shaaban et al, 2021). This lake (LM) is arti cially subdivided into four principal basins by Desert Road and Umum Drain (UD).…”

“…They showed that the water of the MB was improved again, aerated, and became in oxic condition instead of DO depletion. Not only that but also the annual sh production remarkably increased and the sh-esh quality has been improved and becomes safe for human consumption (Shaaban et al 2021).…”

Water resource management and lake rehabilitation is a global interest, to overcome the acute water scarcity facing most urban areas, especially in developing countries. Lake Mariut (LM) is an Egyptian lake that lies south of Mediterranean Sea, and its management had a great interest in Alexandria’s future development and as a part of the environmental sustainability of the Mediterranean basin. LM consists of 4 major basins namely, main basin MB, NWB, SWB, and FB. The MB has deteriorated as it consistently received (sewage and industrial) wastewaters till 2010. This was the date of diversion of the polluting sources as a rehabilitation step. The present work is made after elapsing 8 years from the diversion and aims at monitoring and assessing the status of the water quality not only of MB but also for the other 3 basins too. This was carried out twice, one in cold winter and the other in warm summer. The parameters studied were physico-chemical ones including DO besides nutrient salts (N and P compounds). The results revealed that the waters of both MB and SW basin were depleted in DO to a level difficult to sustain fish life. Tropically, all the studied basins were in eutrophic-hypereutrophic condition. The depletion in the vital DO is catastrophic and needs urgent solution/s. One of the proposed solutions is the dredging of bottom spoiled organic-rich sediments. This and other suggested solutions are, however, discussed, evaluated, and presented.

“…Metal pollution in aquatic environments is caused by a variety of sources, including agricultural runoff, mining and industrial effluents, and domestic sewage (Ali et al, 2019 ; Nour et al, 2022 ; Thabet et al, 2020 ). These metals are distributed across the water, sediments, suspended solids, and biota within aquatic environments, potentially altering ecology and posing health risks to both humans and aquatic organisms (Shaaban, El-Rayis, & Aboeleneen, 2021 ; Shaaban, Tawfik, et al, 2021 ; Yunus et al, 2020 ). Numerous diseases, such as cancer, liver disease, nausea and vomiting, restrictive lung diseases, hypertension, kidney failure, abdominal pain, headaches, and nerve damage, have been linked to the chronic daily intake of high concentrations of some metals in the human system (Al-Kahtany, Nour, El-Sorogy, & Alharbi, 2023 ).…”

The surface sediments from eleven sectors perpendicular to the Egyptian Mediterranean Sea coast, along the delta region, have been assessed. These sectors cover areas of Eastern Harbour, Abu Qir Bay, Rosetta, Abo Khashaba, Burullus, Baltim, Damietta, and Manzala. The assessment process is based on determining the eight metals’ (Fe, Cu, Zn, Mn, Ni, Co, Pb, and Cd) content, followed by applying different pollution and ecological risk indices such as enrichment factor (EF), geoaccumulation factor (Igeo), contamination factor (CF), Pollution Load Index (PLI), degree of contamination (Cdeg.), Nemerow Integrated Pollution Index (NIPI), and Potential Ecological Risk Index (PERI). The results indicate the average concentrations of metals (μg/g) were Fe (18,000), Mn (213), Zn (120), Ni (26), Co (13), Cu (12), Pb (10), and Cd (2). The single-pollution indices reveal that most metals were depleted to metal levels, the sediments were moderately polluted with Cd and unpolluted with other metals, and the CF values confirmed that the sediments were highly polluted with Cd and low contaminated with the rest of the metals. According to the integrated pollution indices, the Eastern Harbour, Damietta, Manzalah, and Bardawil (eastern Inlet) are the most polluted sectors relative to the rest, subjected to various point sources of pollution. Drainage management system is recommended to enhance water conservation and improve fish stocks.

Water resource management and lake rehabilitation are global interest, to overcome the acute water scarcity facing most urban areas, especially in developing countries. Lake Mariut (LM) is an Egyptian lake that lies south of the Mediterranean Sea, and its management had a great interest in Alexandria’s future development and as a part of the environmental sustainability of the Mediterranean basin. LM consists of 4 major basins, namely, main (MB), northwest (NWB), southwest (SWB), and fishery (FB). The MB has deteriorated as it consistently received (sewage and industrial) wastewaters till 2010. This was the date of diversion of the polluting sources as a rehabilitation step. The present work is made after elapsing 8 years from the diversion and aims at monitoring and assessing the status of the water quality not only of MB but also for the other 3 basins too. This was carried out twice, one in cold winter and the other in warm summer. The parameters studied were physico-chemical including water temperature, pH, dissolved oxygen/hydrogen sulfide (DO/H2S), salinity, and chlorophyll a besides nutrient salts (nitrogen, N and phosphorus, P compounds). The results revealed that the waters of both MB and SWB basins were depleted in DO to a level difficult to sustain fish life and showed elevated levels of most nutrient salts. Trophically, all the studied basins were in eutrophic-hypereutrophic condition. As a result of pollution source diversion away from MB to be discharged in the downstream part of Umum Drain (UD), the levels of TN and TP entering Mex Bay through UD were slightly higher than the permissible limit and lower than dangerous loading. The applying of principle component analysis (PCA)-based classification approach, for obtaining the WQI on the current study, revealed that the FB, NWB, and SWB2000 showed a relatively good water quality when compared with MB. The depletion in the vital DO is catastrophic and needs urgent solution/s. One of the proposed solutions is the dredging of bottom spoiled organic-rich sediments. This and other suggested solutions are, however, discussed, evaluated, and presented.
