“…2016 methane, N 2 O and other greenhouse gas emissions were aggregated into CO 2 equivalent emissions in accordance with their respective global warming potential). In the present research, Global Warming Potential (GWP) (kg CO 2 -Eq) was chosen as the main environmental impact because of its worldwide effect, which makes it the greatest environmental challenge presently facing the sustainable water management of the world (Russo et al, 2014). Some other environmental impacts corresponded to acidification (kg SO 2 -Eq), and stratospheric ozone depletion (SOD/kgCFC-11-Eq).…”

There is currently great concern about the processes that directly or indirectly contribute to the potential for global warming, such as stratospheric ozone depletion or acidification. In this context, and provided that treated water is a basic public utility in urban centers around the world as well as in some rural areas, its impact on the environment is of great interest. Therefore, this study applied the environmental methodology of Life Cycle Assessment (LCA) to evaluate the environmental loads of four potable water treatment plants (PWTPs) located in northeastern Colombia following the international guidelines delineated in ISO 14040. The different stages of the drinking water process were thoroughly assessed, from the catchment point through pumping to the distribution network. The functional unit was defined as 1 m 3 of drinking water produced at the plant. The data were analyzed through the database Ecoinvent v.3.01, and modeled and processed in the software LCA-Data Manager. The results showed that in plants PLA-CA and PLA-PO, the flocculation process has the highest environmental load, which is mostly attributable to the coagulant agent, with a range between 47-73% of the total impact. In plants PLA-TON and PLA-BOS, electricity consumption was identified as the greatest impact source, with percentages ranging from 67 to 85%. Treatment processes and techniques, bioclimatic conditions and culturally driven consumption behavior varied from region to region. Furthermore, changes in treatment processes and techniques are likely to affect the environment during all stages of a plant's operational cycle.Keywords: climate change, environmental impact, treated water. Avaliação do ciclo de vida de quatro estações de tratamento de água potável localizado no nordeste da Colômbia RESUMO Atualmente, existe uma grande preocupação com os processos que direta ou indiretamente contribuem para as alterações climáticas, destruição da camada de ozônio ou acidificação, entre outros impactos ambientais. Neste contexto, e desde que a água tratada constitui um serviço público básico em centros urbanos de todo o mundo e em algumas áreas rurais, o impacto de suas emissões no meio ambiente tem sido considerado de grande interesse. Assim, na pesquisa atual foi aplicada a metodologia ambiental de avaliação do ciclo da vida (LCA) para avaliar os impactos ambientais de quatro estações de tratamento de água potável (PWTPs), localizadas no nordeste da Colômbia seguindo diretrizes internacionais da ISO 14040. As diferentes etapas do processo de purificação a partir do ponto de captação por meio de bombeamento para a rede de distribuição foram completamente avaliadas. A unidade funcional foi definida como 1 m 3 de água potável produzida na fábrica. Os dados foram analisados com base no banco de dados Ecoinvent v.3.01 e processados no software LCAData Manager. Os resultados possibilitaram determinar que em plantas PLA-CA e PLA -POR, o processo de floculação tem a maior carga ambiental, o que é principalmente atribuível ao agente ...

Analysis of Factors that Influence the Willingness to Pay for Irrigation Water in the Kurdistan Regional Government, Iraq

Abstract:Water availability has become a problem in many countries of the world. Water scarcity can be economic or physical. Agricultural water use accounts for about three quarters of total global consumption; in many developing countries, irrigation represents over 90% of the water used. The purpose of this paper is to explore the willingness to pay for irrigation water among the farmers from the boundaries governed by the Kurdistan Regional Government (KRG). During the field study, 236 farmers from KRG were interviewed. The collected data were analyzed for each of the precipitation zones of the area (secured (A) and non-secured rainfed (B)). The contingent valuation method was used to determine the willingness to pay for irrigation water. The following possible independent variables influencing farmers' decisions were considered: the bid amounts; evaluation scale of the water deficit; source of water for irrigation; cultivated area; education and age of respondents; main agricultural activity. In Zone A, the median willingness to pay of the farmers that used ground water for irrigation is 20.

“…In recent years, there has been an increase in the domestic use of engineered nanoparticles (Babakhani, Bridge, Doong, & Phenrat, 2017), which has coincided with their release into sewage (Benn, Cavanagh, Hristovski, Posner, & Westerhoff, 2010) and the environment (Hoppe et al, 2015). The presence of these harmful colloids in treated wastewater for irrigation (Russo, Alfredo, & Fisher, 2014) is a risk to human health and the environment (Molnar, Johnson, Gerhard, Willson, & O'Carroll, 2015). In environmental engineering, the performance of novel remediation techniques for soil contaminated with organic materials, metals or halogenated organic compounds using nano-and microparticles (Mueller & Nowack, 2010) depends on accessibility to the contaminated soil sites (Pan & Xing, 2012).…”

The fast and deep percolation of particles through soil is attributed to preferential flow pathways, and their extent can be critical in the filtering of particulate pollutants in soil. Particle deposition on the pore walls and transport between the pores and matrix modulate the preferential flow of particulate pollutants. In the present research, we developed a novel method of combining fluorescence macrophotography and X‐ray computed tomography (CT) to track preferential pathways of colloidal fluorescent microspheres (MS) in breakthrough experiments. We located accumulations of MS by fluorescence imaging and used them to delimit the deposition structures along the preferential colloid pathways by superimposing these images on the 3‐D pore network obtained from CT. Advection–diffusion with transport parameters from the dual‐porosity equation correlated with preferential pathway features across different soil management techniques. However, management did not influence the morphology of the MS preferential pathways. Preferential flow occurred in only a small fraction of the total pore network and was controlled by pores connected to the soil surface and by matrix density. Highlights X‐ray tomography and epifluorescence images were combined to identify preferential pathways in soil. Preferential pathways constituted approximately 1% of the soil bulk volume. Correlations between descriptors of preferential pathways and colloid transport were found. Tillage influenced the morphology of pores, but not the shape of preferential pathways.
