“…with the DWA wastewater discharge limit [33] and was much lower than the levels reported in Alexandria landfill leachate in Egypt (Table 3), Columbia (22,000 μS/cm) and Morocco (26,000 μS/cm) [34,36,38]. However, Rahim et al [39] reported a lower conductivity level of 31.68 μS/cm for landfill leachate in Malaysia.…”

Landfilling of solid wastes has gained increasing acceptance due to the ease of disposal. However, such activity has consequences if the landfill site is not designed according to specification or does not have a leachate liner and collection system. Leachate possesses potential risk to surface and groundwater aquifer within the area surrounding the landfill site. The aim of this chapter is to assess the physicochemical parameters and heavy metal levels in leachate generated from a periurban landfill site situated in Thohoyandou, Limpopo Province, South Africa. Physicochemical parameters were measured onsite using standard methods, while heavy metals were analyzed with flame atomic absorption spectrometer (FAAS) after nitric acid digestion. pH, conductivity and turbidity values ranged from 6.97 to 7.68, 426 to 2288 μS/cm and 12.78 to 295.5 NTU, respectively. Most levels of the determined heavy metals exceeded the effluent discharge guideline limit of South African Department of Water Affairs. This could potentially spike their levels in surface and groundwater. Adequate measures should be put in place to manage the leachate generated from landfill sites.

“…Similar results were reported by Abd El-Salam et al (2015), who collected leachates from landfills in Colombia and Morocco with conductivities of 22 mS/cm and 26 mS/ cm, respectively (Abd El-Salam et al, 2015). However, higher conductivity values of 31.68 mS/cm were presented by Bahaaeldin et al (2010), who studied the leachates from a landfill in Malaysia. Carbonaceous parameters.…”

Sanitary landfilling still is one of the most common management systems of solid urban wastes. The persistent environmental impact of landfills depends on leachate characteristics. The present study aimed at the characterisation of leachate from two landfill sites in the prefecture of Thessaloniki, Greece. Mavrorachi landfill stands in our study as a representative Greek active landfill site, that started operating in 2008. Tagarades landfill has stopped receiving waste from 2008 after 27 years of full operation. In this investigation, leachate samples were physico-chemically characterised so as to assess their pollution potential and their concentration in regard to the type and age of landfill. Elevated concentrations of inorganic and organic constituents were observed in the leachate composition. COD ranged from 2,490 mg/L to 19,700 mg/L, while the respective range for BOD was 390-14,850 mg/L during a 35-year period. The pH values of the leachate samples presented more moderate fluctuations between 7.3 and 8.5. In addition, the ammoniacal nitrogen content increased as landfill age increased, whereas heavy metals concentrations showed significant variations with a slight decreasing trend. The results presented in this paper proved that as time passed, the values of most parameters decreased as the biodegradable compounds are broken down while the refractory compounds resist to biodegradation. Thus, the age has a pronounced influence on the composition of leachate. This study also focused on quantifying the level of contamination that leachates can be potentially cause on a comparative basis by Leachate Pollution Index (LPI). LPI values showed that pollution load was declining but is still not negligible after 33 years.

“…Thus, this outlines the septic tank release valley has been contaminating the dirt just as expanding its harmful not exclusively to the dirt and groundwater yet in addition proficient to affect the fauna and vegetation .The short pathway required for these contaminants before coming to groundwater was improved by intermittent water table changes and penetrating water during the stormy season. Youthful leachates are more dirtied than the stabilized ones where BOD5 may attain till 81,000 milligram per liter for youthful and 4200 mg/l for stabilized specimens [27].BOD5/COD proportion in youthful landfill, where biological action correlate to acid stage of anaerobic depreciation, arrives at value of 0.85 [28]. Aged land-fills create stabilized leachate with comparatively small COD and low mall biodegradability (BOD5:COD proportion less than 0.1).In Morocco, Chofqi et al gathered leachate tests from ElJadida landfill and the mean outcomes indicated that the leachate had high condensation of sulfates and nitrates (1150 mg/l and 290 mg/l, individually).…”

solid wastage yielding in a landfill badly influenced the encompassing condition and people habitat nearer to landfill destinations. Landfill is the most established and the most widely recognized type of evacuation and transfer of waste, comprising the last discarding technique for solid waste in the city. It is outstanding that the effect of MSW landfills leads to contamination of every single natural segment. The negative natural effect of landfills diminished by employing preservation advancements and proper sold waste administration techniques. The nowadays investigation attempted observing of the city wastage landfill effect on the circumference. The spatial attributes of the region affected by the waste dumping and the conceivable effect of leachate utilizing phytotoxicity tests were done. The landfill is built, with base liner and leachate and landfill gas gathering and remedy and curing framework. The transition of leachate and gas from the corpus of landfill into the encompassing condition present a genuine natural concern, which mingle to groundwater squalor, air contamination with sway on atmosphere through methane outflow and potential wellbeing risks. This paper shows an influenced of solid waste land fill in environment. Populaces, particularly those living nearer to the landfill area contamination sources are in danger of both short and long haul impacts of natural, physical and chemical contaminants, including water and food borne sicknesses, substantial metals poisonings and other possibly dangerous components and mixes present noticeable all around, water, soil, particularly in north of Iraq. By and large, there is absence of vital strategies, guidelines and rules in all divisions and at all levels in connection to sheltered and ecological neighborly tasks in agribusiness, industry, vitality, and open administrations.
