AbstractIn this chapter, we explore one aspect of the Anthropocene, the vital, vibrant connections between life and matter (Whatmore, Cultural Geographies 13(4):600–609, 2006.). Drawing on the effectivity of water as a solution and the “Flint water crisis,” we explore how humans tend not to notice matter unless it brings an effect upon them. Our approach follows Melinda Benson, (Natural Resources Journal 59:251–280, 2019) in seeking to decenter human exceptionalism and explore the chemical and biological actors relationally engaged in a system with humans engendering phenomena that are unpredictable as we demonstrate in a case study of the City of Flint and its access to drinking water for humans. As this case highlights, often matter only becomes noticed when it establishes an ontological disturbance forcing itself on human experience and becoming noticed in the process. Important elements of such “noticing” are tied up with the human-material intra-actions engendering phenomena that is shaped by race and geographic history. Rather than constructing Flint and other examples as emergencies or crises that need to be solved, education should explore the dynamic nature of these events and the intra-actions of all elements. This approach offers one strategy for transforming what K–12 science education looks like for both developing scientists and everyday citizens.

As frações granulométricas do solo são consideradas recursos naturais não renováveis, devido a escala de tempo necessária para sua formação. A argila possui elevada disponibilidade na natureza, e por isso seu uso ainda é indiscriminado. É a matéria-prima principal para as indústrias de cerâmica vermelha pulverizadas em todo o território brasileiro. O objetivo do trabalho foi realizar uma discussão acerca do recurso natural não renovável argila e seu uso no processo produtivo da Indústria de cerâmica vermelha. Este foi desenvolvido através de pesquisa bibliográfica, e estudo de caso com realização de visitas técnicas a uma indústria de cerâmica vermelha localizada no município de Paudalho no estado de Pernambuco. No ano de 2013 a Indústria X adquiriu para estoque e consumo 70.161 toneladas, para uma produção de 35.806.268 blocos de cerâmica. De todo o quantitativo produzido houve uma perda de 7,5%, que reflete em 4.768 toneladas de argila e num prejuízo aproximado de R$ 845.835,52. Através do trabalho realizado percebe-se que há uma necessidade de planejamento da exploração e uso dos recursos naturais não renováveis, pois estes podem se tornar escassos e inviabilizar determinados processos produtivos. Isso pode acarretar em conflitos sociais e econômicos, pela valoração dos recursos e diminuição de disponibilidade para uso, ocasionando redução dos lucros por parte dos empresários e por consequência diminuição na oferta de empregos.Use of clay in the production process of the Red Ceramics: A case study in the city of Paudalho, Pernambuco Abstract: The fractions of soil are considered non-renewable natural resources, because the time scale required for its formation. Clay has high availability in nature, and therefore its use is still indiscriminate. It is the main raw material for the manufacture of red ceramic sprayed throughout the Brazilian territory. The objective was to conduct a discussion of non-renewable natural resource clay and its use in industry's production process of red ceramic. It was developed through literature review and case study of technical a red ceramic industry in the municipality of Paudalho in Pernambuco state visits. In 2013 the X Industry acquired for stock and consumption 70,161 tons, for a production of 35,806,268 ceramic blocks. The entire quantity produced there was a loss of 7.5%, which reflects in 4,768 tons of clay and an approximate loss of R $ 845,835.52. Through work is noticed that there is a need for planning of exploration and use of non-renewable natural resources, as they may become scarce and derail certain production processes. This can lead to social and economic conflicts, the valuation of resources and reduced availability for use, resulting in lower profits for entrepreneurs and consequently decrease in the supply of jobs.

AbstractIn order to ensure better availability of water resource to different users, we undertook a dependability study of system for drinking water supply. A real case study was done on the water supply network in the city of El Hadjarin Algeria. We started from the site modelling, which provided a calculation of a Hydraulic Criticality Index (HCI) in order to prioritize the importance of pipes in the network. Once the indices were calculated, a modelling procedure of reliability block diagram was applied. The objective was to study and analyse the existing network to measure the water availability problems and try to provide viable solutions. An action on the structural aspect and hardware may be required in order to ensure better availability of water and make the system more reliable. Spatial modelling is also proposed to be able to monitor different parts of the network where problems may occur.

The overall goal of this case study is to describe the history and present methods that the Philadelphia Water Department (PWD) uses to address its on-going earthy and musty drinking water T&O problems. The Philadelphia Water Department has developed a baseline for its water's aesthetic qualities since the early 1980’s. Philadelphia feels it has sufficient resources to control taste and odour problems. However, when directly asked, only 61–64% of the consumers are satisfied with the taste and odour of Philadelphia's drinking waters. A taste and odour early warning system is being developed for the two drinking water sources, the Delaware and Schuylkill rivers. Secondly, routine T&O panels and chemical analysis of geosmin and MIB are completed. Since the year 2000, 10 ng/L has become an early warning wake-up call for PWD. When higher levels are observed, testing is a priority, the source of the T&O is investigated and consumer complaints are monitored carefully. Present water treatment plants are conventional with chlorine disinfection, coagulation/sedimentation, rapid dual media filtration and final chloramination. The PWD uses powdered activated carbon, river water bypass and hydraulic changes in the distribution system to minimise odour events.

Guaranteeing a safe and continuous drinking water supply for the city of Cali, Colombia, has become a concern for the water company of Cali, the environmental authorities, universities, and entities involved in the water resource. The progressive deterioration of the city's water sources has led to a search for future water sources and/or technologies in order to ensure high water quality standards at minimal costs. This paper describes a variety of problems occurring in the current water supply system in Cali and gives a description of the alternatives that have been considered to solve these problems in the past decades. Multi-criteria analysis was applied to assess alternatives for safe drinking supplies, demonstrating their suitability during the decision-making process when constraints arise due to political, community and institutional interests.

What form do the current and future catastrophes of the Anthropocene take? Adapting a concept from Rod Nixon, this communication makes a case for the notion of slow catastrophes, whose unfolding in space and time is uneven and entangled. Taking the events of Cape Town’s Day Zero drought as a case study, this paper examines the politics and poetics of water in the Anthropocene, and the implications of Anthropogenic climate change for urban life. It argues that rather than being understood as an inert resource, fresh drinking water is a complex object constructed at the intersection between natural systems, cultural imaginaries, and social, political and economic interests. The extraordinary events of Day Zero raised the specter of Mad Max-style water wars. They also led to the development of new forms of solidarity, with water acting as a social leveler. The paper argues that the events in Cape Town open a window onto the future, to the extent that it describes something about what happens when the added stresses of climate change are mapped onto already-contested social and political situations.

Corrosion problems that occur in all fields in engineering activities cause high negative economic impacts, therefore research into operations of different wear mechanisms is a prerequisite for mitigating the effects of corrosion problems can reduce economic loss. Groundwater is  vital and the sole resource in most of the studied region in the city of kufra. In this study, some physical and chemical analysis studies were conducted on the water samples in the study area, which included: pH, total soluble salts, sulfate, chloride, calcium and magnesium. The values of these concentrations in the studied water samples indicate that they constitute a chemically suitable environment for corrosion and precipitation reactions, additionally, the pH values for the studied water samples ranged between (6.02 - 8.2), EC ranges between (266 - 3054) microseism/cm, temperature values ranged from 34.8 C0 to 37.4 C0, TDS between (270 - 1936 ppm). It was found that the Aggressiveness coefficient ranged between (9.03 to 11.58) and this indicates that the water in this region is highly corrosive and the Ryzner coefficient ranges between (8.98 -11.49), which indicates the water condition is the cause of corrosion. The Langelier coefficient index shows that the negative values are the cause of the increase in wear rate values from -2.73 to -0.89.

Original Concept

Considering that more than half of the world’s population today lives in cities and consumes about 80% of the world’s energy and that there is a problem with drinking water supply, this paper presents a way to solve the problem of the sustainability of cities by enabling their complete independence from external sources of energy and drinking water. The proposed solution entails the use of Seawater Steam Engine (SSE) technology to supply cities with electricity, thermal energy and drinking water. The system would involve the seasonal storage of electricity and thermal energy, supported by geothermal heat pumps. The strategy of the distribution network would be based on the original concept of the “loop”. In cities that do not have enough space, SSE collectors would be placed above the lower parts of the city like “canopies”. The city of Zagreb (Croatia) was selected as a case study due to its size, climate and vulnerability to natural disasters. The results show that Zagreb could become sustainable in 30 years with the allocation of less than 2% of GDP and could become a paradigm of sustainability for cities worldwide. This paper encourages the development of the “Philosophy of Sustainability” because the stated goals cannot be achieved without a change in consciousness.
