“…According to the literature the volume of waste water that infiltrates the landfill significantly influences the composition of the leachate as well as the quantity of pollutant released from the waste [2]; in this study the water samples were collected toward the end of the Winter season which is a dry season; that will probably explain why relatively low values of COD were recorded. Furthermore, previous authors [15,16] ( Chang, 1989;Chen, 1996) have reported that higher values (more than 10000 mg/L) of COD must be recorded from leachates of young landfills, while for landfills older than 10 years, lower values (below 3000 mg/L) of COD are expected. Concerns with high uranium values and hardness have been previously reported in the area of Potchefstroom where the Mooi River is loaded with calcium and magnesium originating from the dolomite rocks upstream [17,18].…”

Abstract-In this study, water samples were collected from a borehole upstream of the Sewage Purification Plant (SPP) and from three boreholes at the municipal dumping sites in Felophepa near Potchefstroom and analyzed with consideration of parameters such as pH, conductivity, temperature, turbidity, metal ions and chemical oxygen demand (COD). There was a concern with regard to the quality of water which contained toxic metals such as uranium and lead, relatively high values of turbidity, TDS and COD especially at the sampling point C located in the landfill site at Felophepa. The control sample which was the water from the borehole upstream of the SPP was less polluted, while the sample from point C was the more polluted. Such investigation is encouraged to predict ground water pollution and give feedback to the municipality for proper management of the solid waste disposal at the Felophepa waste dumping site.

“…The pollutant load of the leachate may reach a maximum during the first years of landfill operation, then decreasing gradually over subsequent years, especially in the case of organic compounds [28,29]. Leachate produced in younger landfills contains large amounts of volatile acids, resulted from the acidic fermentation phase, while leachate from old, mature landfills may contain humic and fulvic-like fractions as organics [18,30,31]. Chang [30] and Chen [31] concluded that in leachate from young landfills COD > 10 000 mg/L, while in that from older landfills (more than 10 years), COD < 3000 mg/L.…”

This paper aims to explore information from the literature for emphasizing the state-ofthe art and progress in landfill leachate generation, fate and migration, and treatment. Leachate composition is discussed in terms of types of waste disposed and the processes occurring within landfill. The focus is also on potential pathways of environmental contamination by leachate, which may increase environmental and human health risk. The analysis addresses the opportunity and support for decision making concerning alternatives for leachate management and treatment. Advantages and limitations of treatment methods and processes are discussed considering leachate transfer, physicochemical methods, biodegradation, and combined methods.

“…Secara teoritis, nilai BOD 5 sangat bervariasi bergantung pada usia TPA. Untuk TPA baru atau usia masih di bawah setahun umumnya nilai BOD 5 berkisar 2.000 -30.000 mg/l, sedangkan untuk TPA yang sudah tua (mature landfill) akan berkisar 100 -200 mg/l (3,15) .Gambar 2 memperlihatkan nilai BOD 5 lindi selama periode pengamatan. dengan hasil penelitian Azis (2010) (10) dan AlWabel (2011) (12) .Bervariasinya nilai BOD 5 dalam studi ini tidak menunjukkan adanya variasi dalam biodegradasi organik tetapi kemungkinan disebabkan pada teknik pengumpulan lindi sebelum dilakukan uji di laboratorium.…”

“…Penggunaan paling umum dari COD adalah dalam mengukur jumlah polutan teroksidasi yang ditemukan dalam air permukaan (misalnya danau dan sungai) atau air limbah (3) . Dalam berbagai literatur sebelumnya, lindi dari suatu TPA yang berusia muda akan memiliki konsentrasi organik (sebagai COD) di atas 10.000 mg/l, sedangkan pada TPA yang usianya di atas 10 tahun biasanya COD di bawah 3.000 mg/l (15,16) .Nilai COD juga dipengaruhi oleh tingkat ketersediaan oksigen. Dalam kondisi anaerob (tanpa oksigen) seperti halnya dalam lisimeter ini, kemungkina akan lebih tinggi dibanding dalam kondisi aerob.…”

Keywords:characterization, production, organic, leachate, landfill ABSTRAKSalah satu hasil proses biodegradasi sampah di TPA adalah lindi yang merupakan polutan organik yang berbahaya bagi lingkungan karena berpotensi mencemari tanah dan air tanah. Penelitian ini bertujuan untuk mengetahui kuantitas dan kualitas lindi dari sampah di TPA Kaliwlingi Brebes melalui uji lisimeter. Kuantitas lindi penting untuk memperkirakan spesifikasi disain unit pengolahan termasuk metode pengolahannya. Sedangkan karakteristik lindi penting untuk menentukan efisiensi pengolahan atau target kadar polutan yang diinginkan agar sesuai standard baku mutu. Dari pengamatan diperoleh kuantitas lindi per massa sampah rata-rata mencapai 1.060 liter/kg, sedangkan nilai pH lindi rata-rata 7,6 atau cenderung alkaline. Dari data pengamatan, semakin tinggi kadar air akan semakin besar kuantitas lindi yang dihasilkan. Karakterisasi lindi terhadap parameter BOD 5 , COD, NH 3 -N dan TKN menghasilkan nilai yang bervariasi. Nilai rata-rata serta rentang minimal-maksimal yang didapat; BOD 5 90,7 mg/l (65 mg/l-130 mg/l), COD 9.679,7 mg/l (6.300 mg/l-12.200 mg/l), NH 3 -N 134,4 mg/l (80 mg/l-190 mg/l) dan TKN 672,5 mg/l (540 mg/l-890 mg/l). Rasio BOD 5 /COD sebesar 0,01 menunjukkan tingkat low biodegradability dalam materi organiknya, hal ini disebabkan waktu pengamatan yang relatif singkat dan proses degradasi biologis masih berlangsung.Nilai rasio BOD 5 /COD yang diperoleh belum menunjukkan nilai yang representatif untuk sampah di TPA Kaliwlingi. Hasil dari karakterisasi lindi untuk beberapa parameter menunjukkan bahwa biomassa atau sampah yang diteliti tergolong usia muda dan masih dalam proses dekomposisi.
