In science there is far big gaps between theory, reality and technological applications. The same holds as well for existing enormous gaps between what the UN is wishing to implement in terms of the so-called Sustainable Developments Goals “SDG” and the reality we lived in and we still have to live with. The environmental and ecological situation, in particular water quality around the world, as it exists today did not develop over night and will not disappear over-night. Such reality is the core of lost generation in the past and for decades to come in the future (see earlier posts in http://sustain-earth.com). The real challenges for having sustainable management policies around the world need practical solutions with strong underlying educational and public awareness infra-structures. 

There are huge needs in all education and public awareness systems around the world for basic information and practice on hygiene and sanitation issues (http://www.infonet-biovision.org/content/introduction-hygiene-and-sanitation) with systems for strict guidelines for solid implementation in all small communities and villages in rural areas in the developing countries, e.g. Guidelines for Assessing the Risk to Groundwater from On–Site Sanitation “ARGOSS” (http://www.indiawaterportal.org/articles/guidelines-assessing-risk-groundwater-site-sanitation-argoss).

Indeed, achieving sustainable quality in surface water and groundwater systems and thereby improving ecological and human life qualities in many developing countries, in particular Africa, depend on succsseful sanitation policies as sanitation is an accelerating global threat for water quality, hygiene and health as well as life quality in general.
