Mapping and assessment of groundwater pollution risks in the main aquifer of the Mostaganem plateau (Northwest Algeria): utilizing the novel vulnerability index and decision tree model.

Water plays a pivotal role in socio-economic development in Algeria. However, the overexploitations of groundwater resources, water scarcity, and the proliferation of pollution sources (including industrial and urban effluents, untreated landfills, and chemical fertilizers, etc.) have resulted in substantial groundwater contamination. Preserving water irrigation quality has thus become a primary priority, capturing the attention of both scientists and local authorities. The current study introduces an innovative method to mapping contamination risks, integrating vulnerability assessments, land use patterns (as a sources of pollution), and groundwater overexploitation (represented by the waterhole density) through the implementation of a decision tree model. The resulting risk map illustrates the probability of contamination occurrence in the substantial aquifer on the plateau of Mostaganem. An agricultural region characterized by the intensive nutrients and pesticides use, the significant presence of septic tanks, widespread illegal dumping, and a technical landfill not compliant with environmental standards. The critical situation in the region is exacerbated by excessive groundwater pumping surpassing the aquifer's natural replenishment capacity (with 115 boreholes and 6345 operational wells), especially in a semi-arid climate featuring limited water resources and frequent drought. Vulnerability was evaluated using the DRFTID method, a derivative of the DRASTIC model, considering parameters such as depth to groundwater, recharge, fracture density, slope, nature of the unsaturated zone, and the drainage density. All these parameters are combined with analyses of inter-parameter relationship effects. The results show a spatial distribution into three risk levels (low, medium, and high), with 31.5% designated as high risk, and 56% as medium risk. The validation of this mapping relies on the assessment of physicochemical analyses in samples collected between 2010 and 2020. The results indicate elevated groundwater contamination levels in samples. Chloride exceeded acceptable levels by 100%, nitrate by 71%, calcium by 50%, and sodium by 42%. These elevated concentrations impact electrical conductivity, resulting in highly mineralized water attributed to anthropogenic agricultural pollution and septic tank discharges. High-risk zones align with areas exhibiting elevated nitrate and chloride concentrations. This model, deemed satisfactory, significantly enhances the sustainable management of water resources and irrigated land across various areas. In the long term, it would be beneficial to refine "vulnerability and risk" models by integrating detailed data on land use, groundwater exploitation, and hydrogeological and hydrochemical characteristics. This approach could improve vulnerability accuracy and pollution risk maps, particularly through detailed local data availability. It is also crucial that public authorities support these initiatives by adapting them to local geographical and climatic specificities on a regional and national scale. Finally, these studies have the potential to foster sustainable development at different geographical levels.

Water Quality Assessment in an Area Degraded by Urban Solid Waste in Southern Brazil

ABSTRACTIn most Brazilian municipalities, urban solid waste (USW) is disposed of in open dumps, with numerous sites now being closed, monitored, and rehabilitated. One location, the “old dump” area in the Portão municipality (southern Brazil), previously served as an irregular repository for USW and industrial solid waste (ISW). Its use continued until 1993 when it was closed for a natural remediation process. For this reason, this study aimed to assess groundwater quality in the Portão “old dump,” employing physicochemical, microbiological, and toxicity quality indicators. The study's scope was extended to encompass the Portão Stream as well. Notably, the second collection campaign revealed elevated dissolved aluminum (Al3+), iron (Fe2+), and nitrate levels in all groundwater samples (from PZi wells, i = 1–6), with the PZ3 monitoring well experiencing the most pronounced impact. Further quality indicators, such as total phosphorus, thermotolerant coliforms, BOD5, as well as Al3+ and copper (Cu2+) levels in the second water collection campaign from Portão Stream, were classified as Class 4, suggesting that the water is suitable only for navigation and aesthetic purposes. Conductivity analysis identified Portão Stream as another impacted area. Moreover, during the second collection campaign, the study uncovered an escalation in micronuclei (MN) frequency and chromosomal alterations in PZ5. Downstream water samples from Portão Stream exhibited similarly heightened MN levels. This study's investigation into water quality is a concrete example of the implications of improper USW management. These findings underscore the pressing need for effective waste management strategies to mitigate environmental degradation and protect public health.

Application of optical images and analytical hierarchy process model for solid waste dumping site analysis in Kombolcha town, Northeastern, Ethiopia

Improper open dumping of solid wastes caused different serious problems in fast-growing towns in Ethiopia like Kombolcha town. This unsuitable solid waste dumping management brings health challenges by spreading diseases, contaminating water, polluting air, and spreading of different disease-causing insects such as mosquitoes. Therefore, selecting suitable solid waste dumping site analysis (SWDSA) is very essential to minimize these negative effects related to improper solid waste dumping in such towns. The primary goal of this study is to use optical images and the AHP model to find appropriate solid waste dumping sites in Kombolcha Town. The nine governing factors such as soil texture, geology, faults, groundwater well points (GWWPs, rivers, roads, built-up, Land use land cover (LULC) and slopes, were considered to achieve the aim of this study. These factors were extracted and delineated from the various optical data such as Landsat 8 images, digital elevation model, Google Earth images, geological map, soil map, and also field survey. The factor classes and factors were ranked and weighted utilizing a comparison matrix according to importance and finally by applying the AHP spatial analysis extension tool in Arc GIS software the SWDSA map of the study area was generated. Therefore, as a result of this study about 19.4 km2 (22.8 %), 22.8 km2 (26.8 %), 20.5 km2 (24.1 %), 16.1 km2 (18.9 %), and 6.2 km2 (7.3 %) of the study area falls in not suitable, less suitable, moderately suitable, suitable and highly suitable ranges respectively. Based on the result of this further analysis, D is the 1st suitable site with a score is 83.6 %, site B is the 2nd suitable site is a score is 83.2 %, site C is the 3rd suitable site with a score of 65.1 % and site A is the last suitable site and scored 60.4 %. Therefore, this study strongly recommends that the waste management municipal office of Kombolcha town and other concerned government and non-government bodies apply and consider these identified the best suitable solid waste dumping sites.

Perbaikan pengelolaan sampah rumah tangga dan sampah kebun di Gampong Meunasah Papeun Kabupaten Aceh Besar [Improving household and garden waste management in Meunasah Papeun Village, Aceh Besar District

The waste problem in Aceh Besar District has been going on for quite some time now, which root cause can be tracked back to the lack of waste collection and treatment facilities compared to its residents’ waste growth. Therefore, the amount of untreated waste continues to increase. Meunasah Papeun Village as one of the villages in Aceh Besar District also faces the same problem, where the facilities and capacity of the Village Waste Management Unit (VWM) cannot keep up with the growth of residents' waste. Untreated waste ends up in illegal dumps or is burned by residents. This has reduced the comfort and quality of the village environment. In this Community Development Program (CDP), an approach was taken to reduce the waste that ended up in landfills through education and training on recycling and composting. The process sorted waste into three categories: organic, non-organic and residual waste. Some organic waste was composted and the rest became residue. Non-organic waste was sorted into recyclable and residual groups. This CDP was carried out in collaboration with Bank Sampah USK (BSU) to collect residents' recyclable waste. The residual was collected by VWM to be sent into the landfill. The residents who participated in these activities were able to cut their waste from a third to more than half. The extra money from recycling that was deposited into BSU was an additional advantage.

Leachate analysis of trace metals from e-waste disposed of in landfills and open dumps

Waste electrical and electronic equipment (WEEE, or e-waste) has been largely generated worldwide, but the estimated proportion of WEEE that undergoes the correct disposal is very low. The objective of this study was to evaluate e-waste trace metals in the leachate from disposal of WEEE in soil, using different analytical approaches to determine how these methods may interfere in the results. Different forms of WEEE and MSW landfilling and open dumping were simulated in column reactors to analyse the resultant leachates. Analyses of heavy metals in the leachates were performed in two ways: via inductively coupled plasma-mass-spectrometry with acid digestion of samples, following American Standard 3015A, and via inductively coupled plasma-optical emission spectrometry without acid digestion (US Environmental Protection Agency - USEPA, 2007). Metal concentrations found in the landfill and dumping simulations were similar, but a higher concentration of metals was found in samples with e-waste content, and those undergoing acid digestion prior to ICP analyses. Exceptions were Ba e Zn with a higher concentration without digestion, what may indicate the appearance of matrix effect. Concentrations of Pb, Cu and Mn in the leachates indicate possible interference with MSW. Additionally, it was evident that the timescale of observation influenced the results.

Effects of open dumping site on surrounding air, soil, and water: a case study of Biratnagar metropolitan city

Managing solid waste is one of the emerging challenges in urban areas, and open dumping and burning is common practices mostly in developing countries like Nepal. Which affects the overall surroundings. The study has investigated the effects of open dumping and burning in nearby air, soil, and river water in dumping site of Biratnagar metropolitan city. For studying the effects on air, the three samples of air were taken, at center and 100m upstream and downstream to the direction of wind flow. Soil samples were taken at 10m from the dumping site center, at 25m from the first sample and at 60m from the second sample, and the water samples were taken at leachate and 100 m upstream and downstream to the leachate. Soil and water were subjected to the physiochemical test, heavy metals test and microbes test whereas PM 2.5, and PM 10 were tested for air quality. The results showed that the air from upstream has been seen carrying particulate matter from the dumping site to downstream. Similarly, it is found that the quality of water at leachate and downstream is degraded compared to upstream. The soil quality has been found to have degraded due to the harmful and toxic material of the dumping site. Thus, this study shows that open dumping and burning have affected the nearby air, water, and soil.

Drones and Sustainability: How Technology Can Assist in the Automatic Detection of Waste In Hard-to-Access Areas

Purpose: This work aims to present Unmanned Aerial Vehicles (UAVs), known as drones, as an alternative for environmental monitoring, considering the difficulty of identifying events of illegal dumping in remote areas, whether due to government omission or the difficulty of accessing these locations. These devices provide several benefits, including portability and the capacity to take pictures in real-time from remote and difficult-to-reach places at a cheaper cost without endangering the operator's safety. Design/methodology/approach: The quantity of data gathered by drones needs an enormous amount of effort to analyze and interpret properly due to Rio de Janeiro's difficult topography and large geographic area. To overcome this challenge, artificial intelligence should be used to automatically evaluate and georeference the photos and videos gathered during the investigation. The present work aims to demonstrate the feasibility of this technique in the early and effective identification of remote areas with illegal solid waste dumping by combining a variety of methods, including the use of a global positioning system (GPS), high-precision cameras and sensors on an electronic device for remote sensing (drone), and image processing and interpretation using computational resources. Findings: Following extensive remote sensing in the selected areas, with the assistance of a UAV, the obtained photos were batch-processed utilizing Deep Learning algorithms and digital image processing techniques. After a significant amount of training, these algorithms were able to automatically identify and classify photos that showed signs of solid waste disposal from those that did not, showing that this rapid-automated segregation produced a 92% efficacy. Discussion: Rio de Janeiro produces a lot of trash, much of it is improperly disposed of and indiscriminately deposited in urban and surrounding regions, on hills, and in difficult-to-reach locations. This issue is particularly worse in areas where the government is absent and ineffective, causing citizens to dispose of their garbage in dangerous and hard-to-reach locations. This study offers a Deep Learning-based method for automatically identifying underprivileged communities that require government intervention to reduce irregular garbage disposal and all of the associated environmental consequences.

From perception to action: Waste management challenges in Kassena Nankana East Municipality

This study examines the perceptions and behaviours related to waste management (WM) among residents of the Kassena Nankana East Municipality in Ghana. A mixed-method approach was used to garner data from 394 household respondents, and the data was analysed using SPSS software. The findings reveal a weak correlation between educational attainment and effective waste management practices and a mildly positive correlation between waste awareness and the effectiveness of policies and legislation. Notably, a significant proportion of respondents preferred open burning (42.1 %) and dumping (18.8 %) as disposal methods, indicating critical areas for intervention. The study introduces a novel comprehensive analysis by integrating attitude formation, collective action, and institutional and rational choice theories to understand WM behaviours. This theoretical integration significantly contributes to the field, providing a heterogeneous understanding of the factors influencing WM practices. Furthermore, the research identifies key gaps in WM infrastructure and public engagement, offering innovative recommendations to address these challenges. This study's significant outputs include identifying specific community behaviours towards waste disposal and evaluating the effectiveness of existing WM policies. These findings provide actionable insights for policymakers and stakeholders to develop targeted interventions that promote sustainable WM practices. The study's contributions and recommendations are crucial for advancing environmental sustainability efforts in similar contexts, aligning with the Sustainable Development Goals.

Quantitative microbial risk assessment (QMRA) of the work of manual pit emptiers, commonly known as bayakous.

In Haiti, manual pit emptiers, known as bayakous, face significant health risks. They work by descending naked into latrine pits, exposing themselves to pathogens and contributing to environmental contamination. This study employs the quantitative microbial risk assessment (QMRA) method to evaluate the microbial risks associated with this practice, considering nine prevalent pathogens in Haiti. Three ingestion scenarios were developed: hand-to-mouth contact, ingestion while immersed in excreta, and a combination of both. A sensitivity analysis assessed the impact of input data on study outcomes. The results indicate a high probability of infection and illness during pit emptying operations annually for all scenarios and pathogens. Recommendations include adopting personal protective equipment (PPE) and using a manual Gulper waste pump to eliminate the need to descend directly into the pits, thereby reducing the risk of injury from sharp objects. The study proposes the establishment of intermediate disposal points approximately 5 km from collection sites to deter illegal dumping. National regulations and professionalization of the bayakou profession are suggested, along with awareness campaigns to promote PPE and Gulper pump usage. Addressing these issues is crucial for safeguarding the health of bayakou and public health in Haiti.

UTILIZATION OF BAGASSE WASTE FOR BIO-OIL EXTRACTION FROM SUGARCANE JUICE VENDORS IN BANYUWANGI REGENCY

The disposal of sugarcane bagasse waste, often done through open dumping without further treatment, poses environmental pollution and unpleasant odors. Consequently, the implementation of technology is essential to address this issue, specifically by employing a solid waste recycling technology to produce bio-oil, which holds significant value. Utilizing sugarcane bagasse waste to create bio-oil presents an alternative to minimize aesthetic pollution. This research, sourced from sugarcane bagasse waste obtained from sugarcane beverage vendors in Banyuwangi Regency, explores the conversion of bagasse into bio-oil through the pyrolysis process. Bio-oil is an inorganic compound produced during the pyrolysis process. The aim of this study is to generate bio-oil from underutilized sugarcane bagasse, providing a functional and economically valuable alternative energy source that is both high-quality and environmentally friendly. Additionally, the research aims to determine the concentration and composition of bio-oil resulting from the pyrolysis of sugarcane bagasse. The analysis reveals that the high lignocellulosic content in sugarcane bagasse has the potential to be utilized for bio-oil production.

Chemical Footprint of Open Dumping Sites due to Electronic and Battery Waste

Leachate from open dumping sites is found to be a major threat towards carcinogenic chemical footprint. The present study was conducted to evaluate the supply of various chemicals from electronic and battery (E&B) waste in dumping sites. Various types of E&B waste from household sources are regularly mixed with municipal solid waste (MSW). This study reports the presence of various types of primary and secondary pollutants in MSW from E&B waste. The major organic compounds found in the leachate were various phthalates, pyrrolidone and succinimidederivatives which may be due to the presence of e-toys and battery waste in the landfill. Intrusion of leachate containing these toxic compounds into river and groundwater systems leads to health implications like reproductive and developmental disorders, endocrine disruption and even cancer. It is concluded that a proper E&B waste management is necessary to ensure human and ecological health.

Waste Management of Construction and Demolition Materials Towards Sustainable Growth of Nagpur City

The higher amount of buildings and infrastructures in India, number of construction and demolition (C&D) waste is increasing continuously. These wastes, if not completely recycled, will create the environmental problems. This research paper concentrates on the use of a system dynamics technique to develop a C&D waste recycling. The project is based on the recycling of the rapidly increasing construction and demolition waste. Through this process we want to take a step ahead, the idea of stopping illegal Dumping and ultimately save our mother Earth from destruction. The cost of recycled C&D solid waste resulting in reduction of overall construction cost. The demolition is the most commonly pronounced word in the construction industry. As per the new building rules building should be demolished after its service period. Now-a-days the importance is given to sustainable and environmental friendly construction; there should be effective control of the demolition waste. The demolition waste can be reused for the construction. Construction and demolition (C and D) waste is defined as the solid waste generated by the construction, renovation, repair, alteration or demolition of residential, commercial, government or institutional buildings, industrial, commercial facilities and infrastructures such as roads, bridges, dams, tunnels, railways and airports. Construction and demolition waste is considered as high volume, low risk. It is commonly understood that this waste can be considered a resource, either for reuse in its original form or for recycling or energy recovery. Because of increasing waste production and public concerns about the environment, it is desirable to recycle materials from building demolition. If suitably selected ground cleaned appropriate industrial crushing in plants, these materials can be profitably used in concrete. Despite this, most Construction and Demolition waste ends up in landfills recycled aggregate and recycled sand that can be obtained. Further with the help of the obtained recycled material we intend to make various products such as concrete, paver blocks, hollow blocks, etc which will in turn be less costly as well. These recycled materials and products made from it are economical without any considerable change in the strength and durability aspect. Not only the cost effectiveness but it will also be aesthetically pleasing. According to Metropolitan region development authority the amount of construction and demolition waste (C&D waste) must be reduced by at least 70%. 3Rs model (Reduce, Reuse and Recycle) in the C&D waste management with costs savings. This paper finds a broader understanding of the socioeconomic implications of waste management over time and the positive effects of these policies in the recycled to achieve the goal of C&D waste as well as the composition of Construction and Demolition waste, the need for its recycling and options that can be implemented for its efficient use in the field of concrete technology. Key Words: C & D waste; sustainable construction systems, Recycling, Concrete.

Assessment of the Bacteriological Properties of Indoor Dust in some Classrooms of Delta State University of Science and Technology, Ozoro

The bacteriological properties of indoor dust in some classrooms of the Delta State University of Science, Ozoro was examined with a view to identify any possible source of pollution of classroom indoor air quality; measurement of microbial load of classroom dust sample and to compare findings of selected locations as a means to determine high air polluted areas. This was done by the collection of dust samples from classrooms table and chair surfaces. It was observed that the amount of bacteria available in classrooms differ based on activities in and around the classrooms. Bacteria isolates indicated the presence of pathogen associated with disease such as Bacillus sp; Staphylococcus sp; Micrococcus sp. of indoor air pollution exist and this is identified as open dump practice birthing more microbial cells which are transported through air and poor sanitation practice around and within the classrooms. Contamination of sample was observed for dust at different locations with the bacteria count seen to be higher at sample C (1.8x102cfu/m3) and lower in sample D (0.2x102cfu/m3). Staphylococcus sp dominated all the locations that were analyzed while Micrococcus sp. only occurred in site C. This is because poor environmental sanitation is observed at certain classrooms in addition to shattered classroom windows given an ease of access of dust flow indoor. It can be concluded that only a minimal sources of indoor air pollution exist and hence only a small amount of bacteria is present. In spite of this, prevalence of such practices is likely to promote the growth of more microbial cells.

Impact of leachate on groundwater quality using physicochemical characteristics

ABSTRACT This study assesses the impact of Koshe open dump site leachate on nearby groundwater quality. Groundwater quality is threatened by open dump sites. Groundwater samples around Koshe open dump sites showed elevated levels of various physicochemical characteristics, including Electrical conductivity (EC), Potassium (K), Iron (Fe), Chromium (Cr3), Lead (Pb), Mercury (Hg), Total Alkalinity, Nitrate (NO3−), Phosphate (PO4+), Cadmium (Cd), Bicarbonates (HCO3−), Arsenic (As), Salinity, Cobalt (Co), and Silicon (Si), exceeding Ethiopian, WHO, and EPA drinking-water quality standards. Among the sampled wells, the one located at Ayer Tena High School, upstream of Koshe, exhibited significantly lower concentrations of parameters indicating leachate impact on groundwater quality As, Cd, Cr3, Pb, Hg, Molybdenum (Mo), NO3-, K, and PO4+ compared to others. The presence of these parameters in nearby groundwater wells suggests a substantial impact of the Koshe dump site on groundwater quality. Traditional landfills and dump sites must be outlawed, and new hygienic landfills must be constructed in a convenient location to end the continued groundwater pollution.

Delivery Garbage Behavior Detection Based on Deep Learning

In the context of rapid urbanization, the challenge of effective garbage disposal has become increasingly significant. Traditional methods for addressing illegal littering by pedestrians are not only inefficient but also resource-intensive, demanding considerable manpower and materials. This study introduces a deep learning-based approach for detecting improper garbage disposal behavior. Leveraging advanced deep learning technologies, this approach focuses on object detection, tracking, and human posture analysis to identify and alert against illegal dumping activities captured in video footage, specifically targeting incidents outside designated times or areas. The primary aim is to facilitate prompt detection and mitigate associated health risks. The system uses three deep learning models, YOLOv5, DeepSORT and MobilePose. YOLOv5 is used to identify the human body and garbage bag, DeepSORT is used to track the two, and MobilePose identifies the key points of the human body for posture estimation. The tracking algorithm is used to determine whether to throw garbage.

Hydrogeological assessment and contaminant transport modelling of Enyimba landfill site in Aba, Nigeria

ABSTRACT Commercial and industrial growth in cities generates hazardous waste, often disposed of in open dump sites, contaminating groundwater. Understanding pollutant movement and numerical models are crucial for effective water resource management. This study assessed hydrogeological dynamics and pollutant transfer in the Enyimba landfill site, Nigeria, using field surveys and contaminant modelling to understand groundwater quality and arsenic contamination spread. The research technique included field and laboratory experiments, as well as water sampling during both dry and wet seasons, to evaluate groundwater quality. The geochemical examination of groundwater samples revealed the amounts of several metals using atomic absorption spectrophotometry. The study used contaminant transport modelling with Visual MODFLOW Flex 6.1 and MT3DMS software to simulate groundwater flow and solute transport within the aquifer layers. Predictive simulations over a 20-year timeframe demonstrated the progressive spread of arsenic pollution from the landfill, resulting in an ellipsoid-shaped plume stretching from its source. Arsenic levels have gradually increased, posing a serious threat to groundwater quality and human health. The research highlights the need for remedial measures to reduce groundwater pollution, including waste recovery and recycling facilities and geo-membrane use. It emphasizes proactive actions to protect groundwater supplies and promote environmental sustainability in the Enyimba landfill site.
