“…This tritium content in the leachate is comparable to values from the Breitenau Experimental Landfill in Austria about 2000 TU with a few leachate samples showing 3000 TU. In comparison, three different municipal landfills in Illinois had a range of 227 TU to 8000 TU [11] and a municipal landfill in Metro Manila-Philippines had values about 150 TU to 820 TU [9]. The high tritium content of leachate from plant A was probably due to the older municipal landfill such that part of soluble materials in leachate was relatively higher even compared to the peak of concentration reached in 1963 of around 180.2 TU in Jakarta, the nearest station from studied area.…”

Leaching from Bantar Gebang landfill, Jakarta's main municipal landfill, especially from its two waste water treatment plants (plant A in zone-3 and plant B in Sumur Batu) to underlying aquifer has been studied using isotope techniques. The study was based on the abundances of the heavier isotopes in water molocules namely 18 O, 2 H (deuterium) and 3 H (tritium). Because both water in the waste-water treatment plants and groundwater have undergone different independent physical processes, it was assumed that each water source has its own typical fingerprint in term of the abundances of 18 O, 2 H (deuterium) and 3 H (tritium). Leachate from the two waste water treatment plants have higher 2 H, 3 H activities, and physical parameters (EC, TDS, and pH) values than those of groundwater samples. Because of the age and size of the two waste water treatment plants are significantly different, it was also observed that the isotope contents of plant B, younger age and smaller size, was relatively lower in 2 H values and 3 H activities compared to those of plant A. These phenomena have been used to identify the leaching from wastewater treatment plants of Bantar Gebang landfill to the underlying aquifer. During the dry season, it was observed that 2 H values in leachate were generally higher than those in rainy season. This result might be due to the extensive methane production in the treatment plants. Conversely, 18 O-shifting in leachate from local meteoric line indicated that the leachate had experienced evaporation. Buried luminescent paints in the landfill were most likely the source of high tritium activity in leachate. Based on the samples collected from the study area (mostly from dug or bore wells), it was found that the underlying aquifer especially shallow groundwater has been contaminated up to as high as 33% with leachate.

“…Applications of natural isotopes in landfills for tracing leachate contamination were previously developed in the Metro Manila landfill by Castaneda, et al [9], in New Zealand by Jessica, et al [10], in Illinois-USA by Hackeley, et al [11], in Fresh Kill landfill-Staten Island-New York by Siegel [12].…”

“…During anaerobic condition such as wastes, complete utilization or dissimilation results in the release of organically-bound sulfur as sulfate ion [26]. The lower sulfate concentration than chloride concentration in leachate is due to the microbial reduction of sulfate to sulfide and as an indication of leachate being in methanogenesis phase [15]. In a natural system, nitrates represent the most oxidized form of nitrogen.…”

“…Cations of Ca 2+ and Mg 2+ are easily affected by pH and concentration of another solute such as dissolved organic. They are also subject to sorption, complexation, and precipitation which may lessen their utility as tracers [15]. By understanding the characteristics of those cations, it is more useful to apply Na + and Clto trace leachate movement within its surrounding groundwater.…”

“…From a hydrological point of view, safety analysis of landfill is greatly influenced by shallow groundwater dynamics that take place either locally or regionally. Some parameters that must be well-understood are groundwater origin, direction and rate of groundwater flow, and groundwater characteristics [11,[15][16]. This study is focused on shallow groundwater characteristics using the content of major anion-cation and nitrate dissolved in water in the surrounding of Bantar Gebang landfill.…”

Bantar Gebang landfill located in Bekasi regency is a biggest sanitary landfill in Indonesia which comes up some refusals from local people because of its bad impact on their environment. Major ion contents in leachate and fresh groundwater were investigated during the rainy and dry season to determine contamination by leachate released from Bantar Gebang and Sumur Batu landfill. Leachate contained high concentrations of all major ions that was mainly characterized as a NaKHCO3 water type. On the other hand, most fresh groundwater samples were predominated by CaMgHCO3 and CaMgCl water type. Concentrations of K+, Ca2+, Mg2+, Na+, SO42-, Cl-, HCO3- and NO3- in leachate were to be in a maximum factor of 2110; 7; 6; 143; 20; 112; 349 and 20, respectively than its contents in groundwater. Leachate from Bantar Gebang was detected have a higher concentration than those contained in Sumur Batu that was probably due to its mature leachate. An estimated mixture of leachate to fresh water in monitoring wells (5 m and 15 m depth) was in the range of 20 to 34%, related to Na+ and Cl- signatures, while the shallow groundwater located in residents in the vicinity of these landfills exhibited maximum leachate about 2%.
