Geospatial and Statistical Assessment of Groundwater Contamination Due to Landfill Leachate—A Case Study

Abstract

This study was conducted to measure the impact of a municipal solid waste landfill on groundwater quality around Njelianparamba, a solid waste dumping site in Kozhikode district, Kerala state, India. One of the major problems associated with dumping of municipal solid waste landfill is the release of leachate and its impact on surrounding groundwater. In this study, physico-chemical and bacteriological parameters of groundwater samples collected from the region surrounding the leachate area during the pre-and post-monsoon seasons were analysed. The majority of the groundwater samples contained contaminants at a level beyond the permissible limit set by the Bureau of Indian Standards for drinking water quality. The Geographic Information System software of the Environmental Systems Research Institute, (USA) ArcMap 10.1 was used to prepare spatial distribution maps of different parameters and Leachate Pollution Index and Water Quality Index in the study area were applied to assess the overall quality of groundwater. Characterisation of leachate and groundwater samples revealed that, water in the domestic wells has been deteriorated in response to the percolation of leachate. Additionally spatial and correlation analysis revealed that contamination was present maximum within 300 m radius around the landfill site.

Assessment of Water Quality Status of Guruvayur Municipality

“…Industries discharge hazardous pollutants like phosphates, sulphides, ammonia, fluorides, heavy metals and insecticides into the downstream reaches of the river. A study was reported [5] on the measurement of the impact of a municipal solid waste landfill on groundwater quality around Njelianparamba, a solid waste dumping site in Kozhikode district, Kerala state, India. One of the major problems associated with dumping of municipal solid waste landfill is the release of leachate and its impact on surrounding groundwater Guruvayur or Gurupavanapuri is a municipal town in Thrissur district, of Kerala state in India.…”

“…Step 1: selection of environmental decision criteria 100 In this study, the environmental factors and indicators selected were based on the literature that takes into account the environmental impact susceptibility associated with landfill sites (Leão, Bishop, and Evans 2004;Butt, Lockley, and Oduyemi 2008;Eskandari, Homaee, and Mahmodi 2012;Gbanie et al 2013;Butt et al 2014;Khan and Samadder 2015;Maanifar and Fataei 2015;Motlagh and Sayadi 2015;Eskandari et al 2015; 105 Bahrani et al 2016;Chabuk et al 2016;Chonattu, Prabhakar, and Harikumar 2016b;Demesouka, Vavatsikos, and Anagnostopoulos 2016;Chonattu, Prabhakar, and Harikumar 2016b AQ6 ; Kharat et al 2016;Eskandari, Homaee, and Falamaki 2016;Yıldırım and Güler 2016;Zhang et al 2016). In addition, existing guidelines, relevant legislation and regulations, experts' opinions obtained in informal meetings, and available relevant 110 data were considered in the development of the EISM.…”

“…For this reason, when SW is disposed of above susceptible geological formations, instability of the containment systems and the waste mass may occur resulting in potential contamination of the surrounding surface and sub surface soils and water. Geological criteria were considered in previous studies that investigated environmental impacts caused by SW in 125 landfills (Aydi et al 2016;Bahrani et al 2016;Chonattu, Prabhakar, and Harikumar 2016b;Yıldırım and Güler 2016;Zhang et al 2016). However, these studies did not consider simultaneously the three geological environmental indicators used in the current study, which were (i) distance to faults; (ii) seismic hazard zones; and (iii) distance to karstic areas.…”

“…Climate aspects also were considered in previous investigations, e.g., [44] [57] [59] [82]. In this study, we used the climatic sub-factors of 1) precipitation and 2) temperature.…”
