This essay explains how tiny plastic particles, called microplastics, get into bottled water. It starts with how plastic pellets used to make the bottles are often spilled into the ocean during shipping. Then, the process of manufacturing the bottles creates microplastic dust and fragments that would contaminate the water. The final steps of filling and capping the bottles, especially the act of screwing on the cap, are also major sources of these plastic particles. Storing and reusing plastic bottles makes the problem worse. Studies show that microplastics leak into the water from the bottle's inner walls, especially when bottles are reused multiple times or exposed to heat, such as in a hot car or microwave. This means that from the very beginning of making a plastic bottle to when we drink from it and reuse it, microplastics are constantly being released, creating a serious pollution problem.

The rapid increase in the number of greenhouse gases that may be attributed to anthropogenic activity has led to a significant rise in the average surface temperature of the globe, which in turn has caused global warming. These impacts are assessed using an indication such as global warming potential, represented in units of carbon dioxide equivalent and used to show a region's overall carbon footprint. Human activities' influence on the environment may be measured using a “carbon footprint,” which refers to the total amount of greenhouse gases those activities generate. Carbon Capture Utilization and Storage (CCUS) will play a significant and essential part in India's efforts to cut its CO2 emissions in half by the year 2050 and reach net-zero emissions by 2070. This study identified prospective sources of CO2 emissions from various sectors in India. Additionally, this study investigates the technology for CO2 capture, utilization, and potential storage in India.

This chapter presents a review of the literature published in 2016 on topics relating to wastewater collection systems. It presents noteworthy advances in research and industry experiences selected from major literature sources. This review is divided into the following sections: sewer system planning; sewer asset management/ condition assessment/ rehabilitation; pump stations/force mains/ system design; operations/maintenance/optimization; and regulatory issues/ integrated planning.

Abstract Options for increasing reservoir storage in developed regions are limited and prohibitively expensive. Projected increases in demand call for new long‐term water storage to help sustain agriculture, municipalities, industry, and ecological services. Managed aquifer recharge (MAR) is becoming an integral component of water resources around the world. However, MAR faces challenges, including infrastructure costs, difficulty in enhancing recharge, water quality issues, and lack of available water supplies. Here we examine, through simulation modeling of a hypothetical agricultural subbasin in the western U.S., the potential of agricultural managed aquifer recharge (Ag‐MAR) via canal seepage and off‐season field irrigation. Weather phenomenon in many regions around the world exhibit decadal and other multiyear cycles of extreme precipitation. An ongoing challenge is to develop approaches to store greater amounts of water during these events. Simulations presented herein incorporate Ag‐MAR programs and demonstrate that there is potential to enhance regional recharge by 7–13%, increase crop consumptive use by 9–12%, and increase natural vegetation consumption by 20–30%, where larger relative increases occur for lower aquifer hydraulic conductivity and higher specific yield values. Annual increases in groundwater levels were 7 m, and sustained levels following several years of drought were greater than 2 m. Results demonstrate that Ag‐MAR has great potential to enhance long‐term sustainability of water resources in agricultural basins.

Mountain areas are the source of important cultural, ecological, and life-sustaining resources, but are also subject to devastating losses from floods. To work toward reducing these losses, this paper aims to (a) synthesize understanding on the elements that make flood risk management challenging in high mountain areas and (b) identify practices that can be applied in reducing the exposure and vulnerability of mountain communities. Through a review of the literature and case studies, we identified the flood-related challenges associated with complex topography and hydrogeology, insufficient data and infrastructure, weakly defined governance structures, and sensitivity to climatic and landscape changes. We examined five practices needed for reducing flood risk in these vulnerable areas, involving (1) the acquisition and effective dissemination of information about floods, (2) basin-scale hazard assessment and disaster response planning, (3) clearly defining governance responsibilities and distributing them across multiple jurisdictional layers, (4) implementing effective and diverse mitigation measures, and (5) training and engaging local residents and officials in flood risk reduction. Considerations and needs for implementing these practices in mountain areas are discussed, highlighting the commitment of resources needed for distributed governance, effective planning, land use and building regulations, and engagement of the public.
