This study aims to calculate the avoided leachate volume and treatment cost from waste segregation practices compared to the existing waste disposal methods of landfilling. The mathematical equations were used to analyse the waste segregation rate, leachate volume and treatment cost. The study findings reveal that 99.4% of mixed waste was disposed of in landfills, resulting in an annual generation of 565 thousand cubic meters (m3) of leachate with an estimated treatment cost of MYR 19.82 million (USD 4.36 million). The segregated waste, which accounts for only 0.06%, reduces 354 m3 in leachate volume and a cost-saving of MYR 12.42 thousand (USD 2.73 thousand) in the treatment expenses per year. The findings concluded that waste segregation practice could reduce waste management costs by reducing leachate production and treatment costs and environmental impacts.

“…In their research on evaluating the environmental hazard of dumpsites on the quality of surface water, groundwater, and wastewater, in Baiji city, Hammash and Abed showed Tigris River, groundwater, and wastewater, were contaminated but in varying extents [12]. Another investigation in 2021, given by Alghamdi et al to assess possible environmental hazards relating to MSW landfill leachate currently located in AlMadinah City, Saudi Arabia indicated extreme soil contamination and the most of groundwater in the study area were unacceptable for use as drinking water [13]. Studies on the properties of leachate and its influences on the environment in the area around the dumpsites in Iraq are very few, especially in Al-Diwaniyah.…”

Groundwater contamination presents an increasing concern for environmental sustainability and human health, especially organic contamination. The effect of leachate percolation on groundwater contamination was investigated at Al-Diwaniyah open dumpsite to assess the groundwater quality of hand-dug observation wells surrounding the dumpsite. Samples of raw leachate and groundwater were collected for laboratory analysis, where they were analyzed using standard methods in order to evaluate any potential seasonal and variations for rainy, and dry seasons. Analytical results of leachate samples indicate that all physiochemical parameters were high revealing that they were highly contaminated with both organic and inorganic materials. High pH value and low BOD5/COD ratio for leachate indicated that dumpsite is old and in the methanogenic stage of anaerobic decomposition. In groundwater, average values of pH, EC, TDS, and major ion concentrations were higher in the dry season as compared to that in the rainy season. In contrast, the variation in TSS, BOD5, and COD showed more in rainy season than in dry season. GW1 and GW2 samples were more impacted by leachate percolation than GW3. The findings further revealed that except for pH, and nitrate all other examined parameters were above the permitted limitations of World Health Organization and Iraqi Quality standards. Relying on pH, EC, and major ions respectively, groundwater adjacent to dumpsite can be described as slightly alkaline, water with health hazards, and Chloride is the dominating ion. Inferred from the preceding, the noticeable influence of climate variation and distance from dumpsite on the extent of groundwater contamination. Continuously monitoring the groundwater resources in the area and constructing engineering landfills subject to the environmental limitations to control leachate infiltration into groundwater is recommended.

Groundwater is the primary source for human life, intended for consumption and agricultural production, particularly in the F'kirina plain, a semi-arid region in eastern Algeria. The study aims to determine the hydrogeochemical characteristics of groundwater, including (Ca2+, Mg2+, Na+, K+), CO3, HCO3−, Cl-, SO42−, NO3, PO4−, temperature, pH, electrical conductivity (EC), and total dissolved solids (TDS). The results were analyzed using XLSTAT software (2016) with Principal Component Analysis (PCA), Piper diagram, and four hydrochemical facies. Their suitability for human consumption was assessed by calculating the Water Quality Index (WQI) according to World Health Organization (WHO) standards (2011), with a WQI below 50 considered suitable for human consumption. Samples P3, P5, P6, and P15 were classified as excellent groundwater quality (WQI < 50), while samples P4, P7, P8, P9, P17, and P18 indicated good quality (50 < WQI < 100). However, 50% of the wells showed elevated levels of major elements exceeding the standards. The observed sequence of major element dominance is high quantities of Ca2 + > Mg2 + > Na + > K+, and the anions follow the order of Cl− > SO4 2 − HCO3 − > NO3 −> NO2 −. PCA results revealed two factors influencing overall hydrogeochemistry: geogenic impact attributed to the geological substrate and secondarily to prevailing geochemical (redox) conditions. Conversely, anthropogenic impact is primarily related to agricultural practices leading to nitrate enrichment and salinization. These factors contribute to groundwater quality degradation in f’kirina plain.
