Industry Needs

This paper describes a methodology used to investigate an industrial open dump for its contamination aspects and the possible time for groundwater quality recovery after the implementation of several remedial actions. After 11 years of use of the site for dumping of residues, by the combined use of modelling and geophysics, it was determined that the contamination plume was 65m wide and more than 300m long. The main pollutants are fluorides and other salts. The remedial scheme proposed is basically regrading, impermeabilising the top. As industry needs a place to dispose of its residues it was determined that the best option for the new landfill site is to continue to use the area. The residue must be pretreated to immobilise the fluorides, and the landfill will be impermeabilised at the bottom and at the top. The modelling showed that in a monitoring well 120m below the site, 3½ years after the implementation of the measures the contamination will be only 20% of the initial value, and after 6½ years the quality of the water at that point will be equal to that of the background.

Abstract Municipal waste landfill is a potential, or actual, source of groundwater pollution. Even landfill with a ground containment system can generate leachate that will migrate to aquifers. In this context, it is important to monitor water and leachate and to rationally analyze the existing situation. The purpose of this article was to assess groundwater contamination in the region of the municipal landfill site in Poczesna (Southern Poland) using the Landfill Water Pollution Index (LWPI). Certain physicochemical parameters such as pH, electrical conductivity (EC), total organic carbon (TOC), polycyclic aromatic hydrocarbon (PAH), Cd, Pb, Zn, Cu, Cr, and Hg, were analyzed from samples from six piezometers in the years 2015-2019. The LWPI index values in the groundwater samples ranged from 0.97 to 3.11 (P<0.05). Indicator values that are within the range 2-5 reflect poor water quality with a high visible landfill impact, and those >5 suggest strongly polluted water with a very high landfill impact. The results of this study indicated that the quality of the groundwater in the area around the landfill was better in the case of the Jurassic aquifer compared to the Quaternary aquifer. The results provided by this index are very useful in the context of a quick assessment of groundwater quality. For the purposes of further risk analyses, it is important to consider other variables (chemical components) which can influence groundwater quality in the region of municipal landfill sites.

The Impact

The present study was aimed to evaluate the impact of leachate derived from uncontrolled municipal landfill on surrounding groundwater quality in Kolkata, India. Seasonal variation of twenty physico-chemical parameters in pre-monsoon (PRM) and post-monsoon (POM) season were analysed in forty groundwater samples around the landfill site. Groundwater pollution was identified by the spatial distribution maps of TDS, Na⁺, Cl⁻, Mn and Fe along with the heavy metals like Pb, Hg andCr in both the seasons. Hydrogeochemical characteristics of groundwater samples showed that the area was dominated by brackish water, [Ca⁺2−Cl⁻], [Mg⁺2−Cl⁻] and [Na⁺−Cl⁻] type in PRM season whereas [Na⁺−HCO3⁻] type dominated in POM season. Hierarchical cluster analysis (HCA) was also applied to identify the source of groundwater pollution. In PRM season, groundwater samples closer to the active landfill site were physico-chemically different from upstream samples but more related to downstream samples. However, in POM season, groundwater samples closer to the active landfill site represented distinctly different physico-chemical characteristics from upstream and downstream samples as a result of high influx of leachate pollutants. In specific, the present study urges for proper pollution control measures along with landfill leachate treatment process to improve the surrounding water quality.
