Identification and assessment of water pollution as a consequence of a leachate plume migration from a municipal landfill site (Tucumán, Argentina)

Borehole water has been used as a vital source of water for many communities. The pollution of these boreholes by potentially toxic elements using unlined solid waste dumpsites has posed a significant risk to the populace living around the dumpsite. This study investigates the environmental impact of potentially toxic elements on borehole water within the vicinity of an unlined dumpsite in the Nnewi metropolis. The upstream and downstream samples (16 each) were collected in wet and dry seasons. The potentially toxic elements analysis wasperformed using the methods of the American Public Health Association (APHA) under the required conditions. The quality of the boreholes was assessed using the World Health Organisation (WHO) acceptable limits for drinking water. The risk assessment was estimated for carcinogenic and non-carcinogenic risks using ingestion and dermal routes. The results show that the borehole water wascontaminated with potentially toxic elements through leachate infiltration, which exceeded the WHO permissible limits for drinking water at both locations and seasons. The upstream borehole samples were more contaminated than the downstream samples for both seasons, due to their proximity to the pollution source. The hazard indices of the ingestion and dermal routes showed that the borehole water poses serious cancer and non-cancer health risks for both locations. The results revealed that children are more susceptible to cancer and non-carcinogenic health threats than adults for both locations and seasons. The pollution indices of borehole water for wet season (9.028 and 5.728) and dry season (7.107 and 5.328) for upstream and downstream samples respectively, were polluted and the pollution was higher in the wet season. The borehole water samples were unsuitable for drinking water and should be treated before use.

“…showed almost same results by observing considerable amount of TDS, EC, NO 3 − and PO 4 − 3 in the ground water samples taken from near the land ll site thus concluding that ground water quality is signi cantly affected by leachate percolation. Similarly, Fernández et al (2014) observed the impacts of leachate plume up to 900 m from the land ll site. As the leachate reaches the saturated zone, it forms plume which spreads in the direction of ow of water and contaminates the ground water (Vasanthi et al, 2008).…”

This study was conducted to investigate the effects of municipal solid waste (MSW) used as landfilling on the ground water quality and health effects on the community. The study was carried out in Mardan, Khyber Pakhtunkhwa province- Pakistan. To assess the impacts, 13 ground water samples were collected from Solid Waste Dumping Sites (SWDS) and 13 from Safe Sites (SS). Ground water was analyzed for pH, Turbidity, Electrical Conductivity (EC), Total Hardness (TH), Cl−, Ca+ 2, K+ 1, NO− 2, NO− 3, SO4 − 2; heavy metals such as Pb, Cr, Mn, Cu, Ni, Zn, Cd, Fe; biological parameter such as Total Coliform. Waste sample collected from SWDS showed that food and garden waste were present highest percentage by weight (30.5%) followed by fines (17.3%). The two groups (SWDS and SS) differ significantly for the parameters like EC, TH, COD, Na, Ca, NO3− and SO4 − 2 Ni and TC. Samples collected from SWDS (84%) were found contaminated with TC ranged 2–22. It was analyzed that pH, EC, TDS, COD, TH, NO3−, SO4 − 2, NO2−, Ca+ 2, Na+, TC, Cr, Ni, Zn, Cd and TC were more in the sample collected from 70–130 feet than 140–200 feet. TC found in 70–80 feet depth was significantly different from rest of the groups. Similarly, significant difference regarding different parameters for various depths was found for K+ 1, Ca+ 2, NO2−, Pb, Cu and Fe. The results of the questionnaire survey revealed negative correlation between the diseases and distance from the landfilling sites and significant correlation was observed for typhoid, cholera skin allergies and gastro enteritis. The study confirmed that using MSW as a fill material has contaminated the ground water quality and leveling of land through MSW is not safe. Deep drilling is recommended for extraction of ground water in the contaminated area to minimize the associated health risks.

“…Landfill is a place for various kinds of waste so that leachate contains various types of pollutants that have the potential to disturb the environment and human health. Leachate can seep into the ground, or flow on the ground surface and lead to river water flow [5,6,7,8,9]. Each landfill has different leachate characteristics depending on the processes that occur in the landfill, which include physical, chemical and biological processes [10].…”

Open dumping is the type of landfill used in Terjun landfill. This type of landfill has a high potential for pollution to the environment, especially in groundwater quality. This study aims to determine the quality of groundwater in the Terjun landfill area and its hydrogeochemistry. The methods proposed in this research are Trilinear Piper Diagram Analysis (1944), Stiff Quadrangle Diagram Analysis (1951) and Durov Diagram Analysis (1948). The elements analyzed include Calcium (Ca2+), Sodium (Na+), Magnesium (Mg2+), Potassium (K+), Chloride (Cl-), Bicarbonate (HCO3-) and Sulfate (SO42-). The results obtained on the electrical conductivity value ranged from 100-1100 micromhos/cm, indicating the classification of the water as fresh water. Analysis of the major ion test results of each sample using the three methods shows that the dominant ion content in the borehole groundwater is Cl- ions in borehole 1 and HCO3- ions in the other boreholes. On the Piper diagram, it can be determined that the facies or type of borehole groundwater that has been tested is Ca2+-HCO3-. Then the Durov diagram can be divided into 2 groups, namely the simple dissolution or mixing and reverse ion exchange groups. When looking at the results of the major ion test, sample point 1 has a high level of Cl- ions influenced by leachate water and a fairly close distance to the landfill.
