This scientific event was organized in the context of the Postgraduate Study Programme “Waste Management”, by the Hellenic Open University. The Summer School started in 2015 and was successfully continued since then with tens of wastewater and biosolids experts from many different countries worldwide (USA, China, Greece, Germany, Jordan, Philippines, Spain, UK, Tunisia, etc.), as keynote speakers. Our aim is to establish the Summer School as an important and distinguished distance education e-learning educational scientific event, which will be organized annually. The Summer School is intended for Public and private institutions, graduate students, postdoctoral researchers, and generally scientists interested in the field of wastewater and biosolids management issues. The 2021 program followed the strategy of maintaining basic lectures enriched with new topics of interest on the new trends in wastewater and biosolids management technologies and representative case studies. As special features, the 2021 Summer School: 1) dedicated a session on wastewater management history, focused in China 2) included a session, as in 2019, on practical laboratory exercises and data analysis tools for measuring the basic wastewater parameters requested by regulations 3) offered the opportunity to postgraduate and doctoral students, as well as professionals of waste and biological solids, equipment suppliers, public bodies and organizations to present their work via e- poster in a dedicated special session. This was particularly expected to allow young scientists to attend summer school, interact with each other and facilitate research synergies. 5 Posters on water and wastewater treatment technologies, treatment of emerging contaminants of wastewater (e.g. pharmaceuticals, microplastics), mathematical model development and application, use of treated wastewater in the context of SMART CITIES, QMRA assessment for COVID-19 infection from wastewater, recovery of phosphorus and nitrogen, wastewater and sludge reuse in agriculture, pollution remediation technologies, energy requirements and seismic vulnerability of wastewater treatment plants, biogas production from wastewater treatment, and knowledge and attitudes of students on waste management issues, have been presented. Closing this short preface, I would like to express my deep gratitude to all those who have supported this effort since 2015, and sincerely thank the keynote speakers from the Hellenic and foreign Universities and research institutes, for contributing to a programme of such high quality. We would cordially like to invite all interested parties to disseminate this educational event. We are confident that the participants of WWSS21 have benefited from, and enjoyed the programme.

Conato and Alfonso B. Labao Abstract In this paper, we investigate the environmental impact of the future construction of a military base in the province of Bataan, Philippines. In particular, we assess the sensitivity to pollution of different areas, as measured by the proximity of the area to point sources of pollution - arising from various configurations of the military base. This is done by fixing the current base layout to a certain configuration, and then forecasting the most probable land use in the near term using spatial Markov chain predictions of land use classes. For simulation, we also implement a genetic algorithm to estimate the set of optimal base configurations that minimize sensitivity to pollution while respecting constraints arising from military base requirements.
