Arsenic in drinking water mainly comes from natural deposits leaching into groundwater or from human activities like mining and pesticide use.
Arsenic contamination in drinking water sources is a significant global health concern, stemming from both natural and anthropogenic activities. Naturally occurring arsenic in rocks and minerals can leach into groundwater through weathering and dissolution processes, particularly in regions with specific geological formations such as volcanic areas, alluvial plains, and areas with arsenic-rich sediments. The concentration of arsenic in groundwater is influenced by factors including pH, redox potential, and the presence of other elements. Anthropogenic activities significantly exacerbate the problem. Industrial processes like mining, smelting, and the use of arsenic-containing pesticides and wood preservatives contribute substantially to arsenic contamination. Improper disposal of industrial waste, agricultural runoff containing arsenic-based pesticides, and the use of arsenic-contaminated fertilizers all introduce arsenic into the water cycle. Furthermore, the use of arsenic-containing pressure-treated wood in structures near water sources can lead to leaching and contamination. Finally, the discharge of industrial and municipal wastewater containing arsenic, if not adequately treated, contributes to surface water and groundwater contamination. In summary, the sources of arsenic in drinking water are multifaceted, ranging from natural geological processes to various human activities that release arsenic into the environment.
Smart level concrete, also known as self-consolidating concrete (SCC), is a high-performance concrete that doesn't require any vibration to achieve full consolidation. Its unique properties allow it to flow easily under its own weight, filling even the most complex formwork completely and uniformly, without segregation of its components (cement, aggregates, water, and admixtures). This eliminates the need for vibrators, which are traditionally used to compact regular concrete and remove air pockets. The reduced need for labor and equipment makes SCC significantly faster and more efficient to place. This high flowability also allows for the creation of intricate designs and the efficient construction of complex structures. Further, SCC's improved workability leads to enhanced surface finishes, reducing the post-construction finishing efforts. However, SCC requires careful mix design and precise control of its ingredients to maintain its self-consolidating properties. It is also crucial to ensure that the formwork is designed to withstand the pressure exerted by the flowing concrete. Its applications are broad, including high-rise buildings, bridges, tunnels, and other structures where complex shapes or congested reinforcement are present. The reduced labor cost, improved quality, and faster construction time make SCC an increasingly popular choice in modern construction projects.
