  • Investigating the Levels of Ammonia and Nitrates in Dillon Lake and Their
           Effects on the Environment

    • Abstract: Publication year: 2018Source: American Journal of Environmental Engineering, Volume 8, Number 1Shadi Abu-Baker, Christopher Russell, Joshua DoudnaIt’s a well-known fact that groundwater contamination is a problem in freshwater lakes. Ammonia and nitrates are two of these contaminants, which can cause the premature aging of the lakes and deoxygenation by causing algae to grow out of control. Our goal in this experiment is to determine the levels of ammonia and nitrates in Dillon Lake and their effects on the environment. With this information, we hope to find a way to reverse some of the damage to the lake's ecosystem and raise awareness about this issue. We also hope to connect it to the larger problems in this area. Based on our results, the nitrate and ammonium levels are mostly within the acceptable limits. However, in some areas the nitrate values are high enough to cause spots of excessive algal buildup around the Lake.
       
  • Remedies of Textile Dyeing Effluent by Adsorbents Produced from Indigenous
           Agricultural Waste Products

    • Abstract: Publication year: 2017Source: American Journal of Environmental Engineering, Volume 7, Number 5Md. Azharul Hossain, Shohel Ahmed, Jamal Haider Hasib, Ashique Ul Haque, Rajon Ahmed, Santanu DasAdsorption is typically used in wastewater treatment to remove toxic or recalcitrant organic pollutant (specially Halogenated but also non halogenated) and to a lesser extent, inorganic contaminants, from the waste water. It finds applications in tertiary wastewater treatment as a polishing step before final discharge. In this study three types of adsorbent were used for removal of color from textile dyeing effluent.
       
  • Detection of Drought Cycles Pattern in Two Countries (Sudan and South
           Sudan) by Using Standardized Precipitation Index SPI

    • Abstract: Publication year: 2017Source: American Journal of Environmental Engineering, Volume 7, Number 4Yousif Elnour Yagoub, Zhongqin Li, Omer Said Musa, Muhammad Naveed Anjum, Feiteng Wang, Zhang BoThe aim of this research was to investigate the drought cycles in two countries (Sudan and South Sudan) by using characteristics of Standardized Precipitation Index (SPI) during 1961-2013 to provide valuable information for better adaptation and mitigation of consequences of drought to create a strategically good planning. This study compared the effectiveness of SPI on a long-term scale of (1, 3, 12, 24, 36 and 48 months lead time) drought conditions. The SPI 12-month showed high frequency of droughts in 1966 - 1968, 1974, 1984 - 1985, 1991 - 1992, 2000 - 2003, 2005 - 2006 and 2010. A high frequency of an annual-SPI mild drought was found in: Portsudan, Dongala, Shendi, Khartoum, Alfashir, Geneina, Malakal, Juba and Wau; moderate drought in: Portsudan, Halfawadi, Karrima, Abuhamed, Atbara, Gadarif and Edduim; severe drought in: Aroma, Kassala, Wadmedani, Edduim, Elobeid, Zalingei and Geneina; and extreme drought in: Gadarif, Singa, Abunama, Edduim, Elobeid, Alfashir and Zalingei. Increasing trend of drought, which was associated with the decreasing tendency of precipitation, would reduce the natural vegetation and crop covers as well as livestock production. In fact, this research has revealed that ongoing droughts caused by a decrease in precipitation would eventually reduce the natural vegetation cover, croplands, and livestock production.
       
  • Geospatial Analysis of the Impact of Urban Built-up Development on the
           Distribution of Suitable Solid Waste Dumpsites in Ile-Ife, Nigeria

    • Abstract: Publication year: 2017Source: American Journal of Environmental Engineering, Volume 7, Number 4Eneche Patrick Samson Udama, Nwosu Eberechi Ethel, Abu Hassan OnimisiThe implication of rapid urban built-up development on the siting of suitable solid waste dumpsites in Ile-Ife forms the major thrust of this paper. This study made use of different parameters to identify suitable solid waste dumpsites in Ile-Ife for 2008 and 2013 and determined the spatial growth of urban built-up development for the same epoch. Landsat ETM+ imageries for 2008 and 2013, Google Earth Pro Scenes, ASTER GDEM elevation data, as well as geologic and soil maps were obtained and analysed in. Erdas Imagine 9.2, ArcGIS 10.5 and Minitab 17.0 environments. Classification and extraction of geospatial data earmarked for the study, including road, water body, soil, underlying geology and slope were performed with the aid of simple model builders, Multi-Criteria Evaluation (MCE) analysis and Chi-square statistic. The result revealed that Ile-Ife town had a frequency of change in urban built-up area of about 1.91sq.km per year and experienced a reduction of moderately and highly suitable solid waste dumpsites and an increase in unsuitable ones. The Chi-square result (P-value = 0.006; -level of 0.05) revealed a significant difference in dumpsites suitability categories for the period under investigation. It was therefore concluded that in view of sustainable urban development, there is need for restrictions to be given for urban built-up development as it affects the limited areas suitable for waste disposal in Ile-Ife. The study also proved the flexibility of smart geospatial techniques (by which future scenarios can be predicted or simulated), thus recommended for environmental managers and urban planners.
       
  • Modeling and Optimization of Structural Steel Corrosion Inhibition using
           Barely Grass Extract as Green Inhibitor

    • Abstract: Publication year: 2017Source: American Journal of Environmental Engineering, Volume 7, Number 4Ammar Ali, Sarah Falih, Nedal Yousif, Reben Rezgar, Ibtisam KamalThe work deals with studying the corrosion inhibition of structural steel in acidic medium (0.1M HCl) using barley grass extract as inhibitor. The effect of the concentration of inhibitor (432-768) ppm, time (15.3-176.7) h, and temperature (24-44)°C on corrosion rate, inhibition efficiency and degree of surface coverage of the metal alloy was investigated using Response Surface Methodology (RSM). Fitting of degree of surface coverage with Freundlich adsorption isotherm was conducted. The kinetics parameters of corrosion and inhibition processes including the activation energy and frequency factor were estimated as well as the thermodynamic parameters including the standard free energy of adsorption Δ G°ads, the entropy of activation (ΔS*) and enthalpy of activation (ΔH*). The corrosion rate was found to increase with increasing time and temperature, while the inhibition efficiency was found to increase with increasing the inhibitor concentration and decrease with time and temperature. The RSM analysis results revealed that maximum corrosion rate of about 2.11 mg/h resulted at 42°C and 164 h without using inhibitor compared to 0.26 mg/h at 43°C and 72 h with using the green inhibitor respectively. The value and the negative sign of ΔG°ads indicated that the inhibitor molecules adsorbed spontaneously onto the metal surface via physiosorption. The positive shift of enthalpy of activation in presence of inhibitor reflected that the process of adsorption of the inhibitor on the alloy surface is an endothermic process and the negative values of entropy of activation represented association rather than dissociation of the inhibitor indicating the decrease of system disorder due the adsorption process. According to the estimated results, barely grass extract could be recommended as low cost green inhibitor for acid corrosion inhibition of structural steel used in manufacturing industrial equipment and vessels.
       
  • Reliability of the Environmental Feasibility Studies to the Mining and
           Construction Projects: A Case of Mara River Basin in Tanzania

    • Abstract: Publication year: 2017Source: American Journal of Environmental Engineering, Volume 7, Number 3Benson Rugalema Mwemezi, Valentine G. M. LuvaraThis study investigates different predictions of environmental feasibility studies, identifies environmental impacts due to mining and construction activities, correlate the impact as predicted by the environmental feasibility studies with the actual impact on site and lastly recommends enhancement on the procedures of the environmental feasibility study, that if are practiced the Mara river basin will be better protected. This study was conducted in North Mara Goldmine and VIP lodge construction project in Mara region. Data were collected using document review, questionnaire, interviews and field observations using both convenience sampling and judgmental sampling. The study revealed loss of biodiversity, deforestation, high turbidity to water, presence of acid mine drainage and poor waste water management. It is thus recommended that monitoring during the project implementation should be done seriously by professionals adhering to their ethics and code of conducts. Source of construction materials specified should consider the impact to environment before giving out the building permit. Fully community involvement in preparation of the environmental feasibility studies is needed. There must be control of small scale mining activities. There must be an integrated water resources management plan for the conservation of water sources and lastly, construction and mining professionals should be more proactive in developing actions for the environment with a proper management approach to environmental assurance.
       
  • Effect of Different Sets of Pleurotus ostreatus and Aspergillus niger
           Hydrolysis of Cassava Peelings on Bioethanol Yield

    • Abstract: Publication year: 2017Source: American Journal of Environmental Engineering, Volume 7, Number 3Michael N. Worfa, Moses Mensah, Benjamin Afotey, Samson P. SalifuThis study investigated the effect of three different types of microbial activity on bioethanol yield from cassava peelings. The cassava peelings were pretreated by milling to 2mm particle size, autoclaved and hydrolyzed using Pleurotus ostreatus k910 (white-rot fungi), Aspergillus niger Menae1 (black molds) and a combination of the two fungi. The hydrolysates obtained were subsequently fermented to ethanol using the Saccharomyces cerevisiae (baker’s yeast). The analysis of lignocellulose fractions, fermentable sugars and bioethanol produced were performed using a van Soest, refractometry and gravimetric methods respectively. The effect of the various fungi used for biological pretreatment/hydrolysis on lignocellulose fractions and fermentable sugars released of each substrate were studied. P. otreatus k910 hydrolysis of the cassava peelings yielded an optimum fermentable sugar concentration of 34.11 g/L compared to 28.64 g/l for the A. niger MENAE1. However, the combination of the two fungi for hydrolysis gave the best results for fermentable sugar produced of 36.51 g/l for cassava peelings. The fermentation results revealed that the maximum ethanol yield for cassava peelings is 19.36% (w/w dry biomass).
       
  • Elemental Analysis of River, Marshes and Ground Water in Thi Qar Region,
           Iraq

    • Abstract: Publication year: 2017Source: American Journal of Environmental Engineering, Volume 7, Number 3Muhanad H. H. AlrakabiThe elemental analysis of the samples collected from marshes water and river water in Thi Qar region of Iraq are done using the X-ray fluorescence technique (XRF). The water samples are collected from Euphrates River, Al- Hammar marshes, ground water and drinking water. The elements observed in various samples are 20Ca, 26Fe, 29Cu, 30Zn, 33As, 35Br and 38Sr. The 20Ca concentration in Euphrates river water constitutes ͂ 2.3% of the left over residue, a value similar to that observed in water from the marshes. The 38Sr concentrations in the Euphrates river water is in the range 2519-5691μg/L. The 38Sr concentrations in Euphrates River are similar to that observed in the marshes water. In Al-Hammar marshes, the concentration of 34As is estimated to be in general below 5 μg/L. The 35Br concentration in various samples collected from Al-Hammar marshes are in the average value =1108 μg/L. The 35Br concentration in various samples collected from Euphrates river are in the average value =676μg/L. The water from Euphrates river is not safe for use for drinking water supply due to high bromine content and the water from the drinking water schemes from the river needs to be monitored for the presence of bromate ions.
       
  • Hydraulic Performance Evaluation of Integrated Operation of Pressurized
           

    • Abstract: Publication year: 2017Source: American Journal of Environmental Engineering, Volume 7, Number 2Tsegay Weldu HailuPressurized irrigation system (sprinkler and drip) is one of the modern/artificial water applications irrigation systems to the soil or plant. A poor designed and managed pressurized irrigation systems result in non-uniform water distribution. In addition to this, its performance may also deteriorate with time due to wear, lack of maintenance, clogging and other physical and environmental factors. Since pressurized irrigation system is easily influenced due to wear, lack of maintenance, clogging and environmental factors it is recommended to carry out its performance evaluation periodically soon after the system’s installation. The general objective of this study was to evaluate the performance of integrated pressurized irrigation systems that is found in Raya Valley, specifically Selam Bkalsi farm area which is found near Alamata town. The data used to evaluate the hydraulic performance indicators of the existing integrated pressurized irrigation system in the farm area was collected through catch can experiment and questionnaire survey methods. The results obtained in sprinkler system indicate 87.78% for Christiansen uniformity coefficient (CU), 81.58% for distribution uniformity (DU) and 83.37% for application efficiency (Ea). While the result obtained in drip system indicates 73.86% for Christiansen uniformity coefficient (CU), 57.1% for emitter flow variation (qv), 27.8% for coefficient of variation (Cv), 69.38% for Emission uniformity (EU), and 72.15% for statistical uniformity (Us). In this study, the integrated pressurized irrigation system (sprinkler and drip) over the study area as a whole was not operated well efficient. According to the parameters used to evaluate the existing operational pressurized irrigation system over the specified study area and compared to the specified standards, sprinkler irrigation system has good performance as well as the drip irrigation system has less performance. Generally in the study farm area sprinkler system is well performed.
       
  • A Decision Support Tool for Sustainable Land Use, Transportation,
           Buildings/Infrastructure, and Materials Management

    • Abstract: Publication year: 2017Source: American Journal of Environmental Engineering, Volume 7, Number 2Eric S. HallOne issue for community groups, local and regional planners, and politicians, is that they require relevant information to develop programs and initiatives for incorporating sustainability principles into their physical infrastructure, operations, and decision-making processes. This research project addressed the issue through two research questions. The first research question that this project was designed to address, which was greatly influenced by the vast number of references in the sustainability literature, was an ontological one, “what are the major categories that sustainability decisions can be grouped under, and how might those categories be related'”. The second research question that this project answered was, “how can information contained in the sustainability literature be made accessible to users in a convenient format'”. The Multi-Sector Sustainability Browser (MSSB) is a decision support tool (DST) designed to synthesize and summarize research in four sustainability decision domains, Land Use, Buildings and Infrastructure, Transportation, and Materials Management in a manner that provides easy and rapid access to information for use in planning and decision making. Weblinks are provided to reference documents and resources from the four sustainability decision domains, allowing users to download relevant documents and extract information in support of sustainability decisions and related program initiatives.
