Assessment of the impact of landfill on groundwater quality: A case study of the Pirana site in western India

Abstract

In present study focus has been given on estimating quality and toxicity of waste with respect to heavy metals and its impact on groundwater quality, using statistical and empirical relationships between different hydrochemical data, so that easy monitoring may be possible which in turn help the sustainable management of landfill site and municipal solid waste. Samples of solid waste, leachate and groundwater were analyzed to evaluate the impact of leachates on groundwater through the comparison of their hydrochemical nature. Results suggest the existence of an empirical relationship between some specific indicator parameters like heavy metals of all three above mentioned sample type. Further, K/Mg ratio also indicates three groundwater samples heavily impacted from leachate contamination. A good number of samples are also showing higher values for NO À 3 and Pb than that of World Health Organization (WHO) drinking water regulation. Predominance of Fe and Zn in both groundwater and solid waste samples may be due to metal plating industries in the area. Factor analysis is used as a tool to explain observed relation between numerous variables in term of simpler relation, which may help to deduce the strength of relation. Positive loading of most of the factors for heavy metal clearly shows landfill impact on ground water quality especially along the hydraulic gradient. Cluster analysis, further substantiates the impact of landfill. Two major groups of samples obtained from cluster analysis suggest that one group comprises samples that are severely under the influence of landfill and contaminated leachates along the groundwater flow direction while other assorted with samples without having such influence.

Evaluation of seasonal variation of water quality using multivariate statistical analysis and irrigation parameter indices in Ajakanga area, Ibadan, Nigeria

“…The suitability of groundwater resources for irrigation purpose was also studied (Sujatha and Reddy 2003;Sadashivaiah et al 2008;Ramesh and Bhuvana 2012). Several published research studies have employed the use of multivariate statistical analysis in the interpretation of groundwater quality data obtained from various sources (Sundaray 2010;Singh et al, 2008;Uddamari et al 2014;Oketola et al 2013;Molla et al 2015;Arslan 2013;Zhang et al 2014;Majolagbe et al 2016;Markic et al 2015;Razmkhah et al 2010). Scientists have also employed the use of principal component analysis (PCA) to study soil physicochemical properties and its geochemical constituents, identification of heavy metals pollutants in soil, analysis of heavy metals presence in dust and evaluation of influence of seasons on air pollution (Adhikari et al 2003;Ma et al 2016;Satyanarayanan et al 2016;Gergen and Harmanescu 2012;Iwara et al 2014;Lu et al 2010;Burt et al 2014;Benhaddya and Hadjel 2014;Abdul Raheem et al 2008).…”

Ammonium Concentration and Migration in Groundwater in the Vicinity of Waste Management Site Located in the Neighborhood of Protected Areas of Warsaw, Poland

“…The leachate commonly contains large amounts of organic matter, ammonium, heavy metals, and chlorinated organic and inorganic salts, which cause a great threat to soil-water environment in the vicinity of a landfill site [16][17][18][19]. The compositions of leachate can be divided into four parts of pollutants: (1) Organic matter, COD (chemical oxygen demand) and TOC (total organic carbon); (2) specific organic compounds; (3) inorganic compounds; and (4) heavy metals [6,11,20].…”

Impact of the Municipal Solid Waste Łubna Landfill on Environmental Pollution by Heavy Metals

“…Studies in other locations have indicated that MSW landfills can significantly affect the contamination of groundwater with heavy metals: Ahmadabad (Cd-0.003, Pb-0.042 [31]; and Calcutta [32] in India; Ibb City in Jemen [33]; Cartagena in Colombia [34]; Vejen landfill in Denmark [35]; Ano Liosia landfill in Greece [36]; and Zagreb in Croatia [37]. The contents of all analyzed heavy metals (Table 3) in the subsurface soil horizon (0-25 cm and at 25-50 cm) were low, as is commonly observed for farmlands and forest areas in Poland [38].…”
