Environmental impactRecently, due to growing evidence of environmental impacts and the increased emphasis on artificial recharge using reclaimed water, endotoxins are under increasing interest. This research assesses the endotoxins in different treatment plant influents which are not designed to treat these chemicals. It generates data towards improvement of existing wastewater facilities to address endotoxin issues to maintain clean water environments, which is likely to create positive environmental impacts on sustainability of water and ecosystems. It considers the augmentation of drinking water supplies as a means of achieving a sustainable water supply and significant environmental benefits through protection against drought. Environmental sustainability is to be achieved once water resources are not lacking. Moreover, this study will enhance human trust to reuse practices.
