River basins appear to be important in the Philippines due to rising water demand for residential needs, agriculture, commerce, and industry. While the country has a total available freshwater resource of 145,900 million Cubic Meters per year based on an 80% probability for surface water and 20,000 million Cubic Meters per year for groundwater recharge or extraction (ASEAN, 2005), the concern for sustainable water supply continues to be a major concern due to the continued degradation of river basins and watersheds.

Research on water Fe removal by Eichhornia crassipes and Pistia stratiotes L. on the Constructed Wetland (CW) system was carried out to know the efficiency of Fe removal on the Surface Flow Constructed Wetland (SF-CW) system. The research was conducted on well water in Selat Makmur Village, Beruntung Baru District, Banjar Regency, South Kalimantan Province, Indonesia. Fe concentration in existing well water is 2.24 mg / L; compared to the Regulation of the Minister of Health of the Republic of Indonesia No. 32 of 2017 concerning water health requirements for sanitary hygiene purposes, the well water exceeds the predetermined quality standards. This study used six reactors where two reactors contained Pistia stratiotes L.; two reactors had Eichhornia crassipes and two other reactors without vegetation as control reactors. The dimensions of each reactor are 90cm x 30cm x 45cm, operated for 20 days with a residence time of 5 days. The density of P.stratiotes L. and E.crassipes used was 540g/108L wet-weight. The highest Fe removal efficiency of SF-CW with P.stratiotes L. vegetation occurred on the 15th day at 85.11%, and SF-CW with E.crassipes on the 10th day at 89.32%. The results of this study show that both vegetation with the SF-CW system can be considered for use by the surrounding community because this vegetation can remove Fe.

In Israel, desalinated water is a major source of drinking water. Previous studies have suggested that the levels of iodine in water provided by authorities may not accurately reflect the levels reaching end-users. Materials and Methods: We analyzed 21 tap water samples collected from different localities across Israel, 13 posttreated desalinated water samples from three of the largest Israeli desalination plants, and several natural water samples. An improved method of ICP-MS developed in our laboratory was used to analyze the content of iodine and other macro-elements, and determination of iodine was performed in alkaline media. Results: Our results showed that it is possible to distinguish between sample groups based on iodine concentration, water hardness, and Ca/Mg ratio. The median iodine concentrations for four groups of tap water samples ranged from 0.3 to 12.3 μg/L, which is lower than the concentrations previously reported by other researchers in Israel. Based on typical consumption, the water samples can provide no more than 3.39% of the recommended dietary allowance level for iodine. The analysis of post-treated desalinated water samples indicated that these waters comply with industrial specifications but contain only trace concentrations of iodine and much less magnesium than recommended by different public health authorities for public consumption of drinking water. Conclusion: The total iodine concentrations found were lower than several observations reported in previous years in the literature. There are currently no strict regulations regarding iodine and magnesium levels in drinking and/or softened (desalinated) water, but the intensive desalination plant application is already exhibiting a negative impact on public health. Further investigations are needed, but the present study provides useful insights for developing an effective policy to ensure adequate iodine supply for the population of Israel through drinking water.

LPlastic reuse stands as a pivotal strategy in the battle against environmental degradation. By giving plastic products a second chance, we significantly mitigate the burden on landfills and the natural world. This approach not only conserves resources but also diminishes the energy expended in the production of new plastics. Through creative reimagining and repurposing, we transform what might have been waste into valuable assets, from upcycled containers to innovative construction materials. Embracing plastic reuse not only reduces our reliance on virgin plastics but also fosters a culture of sustainability and resourcefulness, essential for building a more resilient and harmonious relationship with our planet.
