“…The Igbo-Etche, Eluozo and Rumuolumeni study stations during the dry season recorded mean concentrations of Phosphate as 0.314, 5.160 and 2.526 mg/l. These concentrations are in agreement with those earlier observed in other researches for leachates [18,19,26,28]. Phosphates values were all below the permissible limits by both WHO and FMENV standards.…”

This study was carried out to determine the levels of available nutrient parameters present in leachates from some selected dumpsites in Port Harcourt metropolis. Leachates from the 3-selected dumpsites were analyzed and compared with the seasons, controls and established standards using descriptive and analytical designs. Integrated samples were collected during both wet and dry seasons and analyzed for NO3- PO43- , SO42- and NH4+. The use of 2-way ANOVA, t-test and mean variation were applied to explain trend and seasonal variations. The results showed that there was no significant difference in temporal dimension (seasonally) but there was a high level of spatial variation (stations) in most measured parameters. Though some of the parameters were relatively low compared to standard limits; the study revealed that these dumpsites remain major polluting and nutrient enriching sources to the ecosystem. In order to reclaim these dumpsites from acute contamination, government at all levels should ensure the introduction of active remediation processes alongside physico-chemical methods which can ameliorate the effects of pollution in the environment.

“…Aboho et al, [17] recorded rainy season values which were 11.78 and 13.76 at two study stations. Nartey et al, [18] recorded lower mean nitrate concentrations during the dry (1.95) and rainy (2.125) seasons. This trend of higher nitrate values during the rainy season confirms similar trend in this study.…”

“…Similar results were found in the landfill of El Hajeb, Morocco, with a concentration of approximately 43 egg/L (Gamar and Hilali 2017). Also, lower concentrations than our results of 1.66 egg/L were found in the Oblogo landfill in Ghana (Nartey et al 2014). However, this kind of parasite is absent in the Sarbah landfill at Weija in Accra (Sackey and Meizah 2015).…”

Leachate of the uncontrolled landfill contains pollutants, which is discharged directly into the environment. The main objective of this study is to evaluate the reduction of bacteriological and parasitological risks by four biological treatments: sequencing batch reactor, anaerobic, intensive aeration and combination of the three processes. The results showed high bacteriological pollution in the raw leachate: 1.12 × 10 7 CFU/ml, 6.7 × 10 6 and 5.26 × 10 4 for total coliforms, faecal coliforms and Streptococci, respectively, parasites of intestinal helminths are also present: 11.86, 9.49, 9.83, 8.81 eggs/L for Enterobius vermicularis, Ascaris lumbricoides, Trichuris and Hymenolepis nana, and the values are higher than the standards for discharge into the natural environment. After sequencing batch reactor treatment, a decrease is noted in bacteria, Staphylococci, total coliforms and Streptococci with 99.63%, 97.11%, 99.93% and 94.62% abatement, respectively. This process also removes 75% of total unviable form and 80% of viable form of parasites. Intensive aeration and anaerobic treatments allowed the total elimination of total coliforms. Anaerobic processing allowed a reduction of 33.4% of unviable forms and 37% of viable forms of parasites, while a reduction of 63% of unviable and 77% of viable parasites was reported by intensive aeration. The combined treatment improves the results with abatement rates to 100% for total coliforms bacteria, and viable forms of the genus parasites: Capillaria sp., Toxocara (nematodes), Hymenolepis nana and Taenia (cestodes). A principal component analysis showed very significant correlations between all measured variables (bacteria and parasites). Combined treatment appears to be the best treatment to reduce biological risks of leachate.

“…Mechanisms of contaminant removal include leaching of inherently soluble materials, leaching of soluble biodegradation products of complex organic molecules, leaching of soluble products of chemical reaction and washout of fines and colloids (Hennebert et al 2013). The characteristics of the leachate produced are highly variable, depending on the composition of the solid waste, precipitation rate, site hydrology, compaction, cover design, waste age and interaction of leachate with the environment and landfill design and operation (Nartey et al 2012). Leachate from decomposed solid waste conveys heavy metals such as Fe, Cu, Cd, Ni, Pb, Zn etc.…”

An investigation was carried out to assess the characteristics of leachate and its impact on surrounding agricultural land of the Matuail landfill site, Dhaka, Bangladesh. Leachate samples were collected from active dumping areas; soil and plant samples from three different sites of surrounding agricultural areas. Water quality parameters like pH, DO, BOD, COD, TDS were measured for leachate samples and heavy metals like Cu, Zn, Pb, Cd, Ni were analyzed for leachate, soil and plant samples. The results showed that untreated leachate concentrations of DO, BOD, COD and TDS were 1.34, 96, 1343 and 7120 mg/l, respectively that exceeded inland surface water standard but the concentrations of DO (7.49 mg/l), BOD (10 mg/l) and TDS (790/l) in the treated leachate pond were found within the permissible limits. The leachate samples are not contaminated with heavy metals as these are present below the toxic limits. The heavy metal concentrations in agricultural soils are below the permissible limits except Pb; but in plants the concentrations of Cu, Zn and Pb exceeded the critical limits.
