“…Several cases determining groundwater leachate pollution using analytical, geophysical and chemical methods were reported in the literature (MacFarlane et al 1983;Reinhard et al 1984;Albaiges et al 1986;Pastor and Hernández, 2012). There are limited references to experimental or mathematical modeling setups that were used to determine groundwater contamination due to uncontrolled solid wastes disposal.…”

The construction of large infrastructure projects such as highways, railroads, landfills, airports, harbours offers great social-economic opportunities for the development of a region; it is also mainly responsible for the deterioration of natural environment in the greater areas where these projects are located. The goal of environmental impact assessment (EIA) that is carried out before the construction of such a project is to propose measures and actions that will limit negative environmental impacts during its construction and operation phases. The common perception is that large scale infrastructure projects can only damage natural environment even though very strict environmental requirements are imposed by the Authorities. This was not the case in Eleonas Attikis region in Greece where METRO facilities were built. During the construction phase, hazardous solid wastes were found buried in the urban area where METRO facilities (station, tunnel and depot) were located, raising serious environmental issues in natural and human environment in the region.The protection and restoration of environment in an uncontrolled waste dumpsite require accurate estimation of subsurface pollution extent and intensity. The scope of the present analysis is to map the contamination in the aquifer of Eleona Attikis where METRO facilities (station, tunnel and depot) were built. Numerical modelling approaches were used to estimate environmental impacts of this project to soil and water resources in the greater region. The results have shown that the removal of buried solid wastes to construct METRO station and depot was crucial in order to eliminate negative impacts in soil and subsurface water resources. An impact assessment of hazardous solid wastes buried for many years in the aquifer was also performed. The findings of this analysis proved that the implementation of a large infrastructure project such as the one in Eleona Attikis Greece was environmentally beneficial for the region.

“…Yet, the potential for natural attenuation of CAHs is by no means universal or even presumed. Case studies repeatedly demonstrate that there are no general characteristics that can be identified to easily and correctly predict the potential for natural attenuation of CAHs at any particular site (Parsons, 1999, Reinhard et al, 1994. Consequently, the integration of natural attenuation processes into the recognized management strategy for MSW landfills will need to be completed on a site-by-site basis.…”

“…Sealing relies on the collapse of the formation or the emplacement of alternating sand and bentonite layers around the PVC casing, which requires again a costly larger diameter borehole. Bundle wells consisting of a series of tubes reaching different depths installed with a direct-push machine is a widely used costeffective alternative (Cherry et al 1983;Mackay et al 1986;Reinhard et al 1984). This method has mainly been used in sand aquifers, where the formation collapses after retrieving the casing, sealing the annular space around the tubes.…”

Direct-push multilevel sampling system for unconsolidated aquifers

2013

An economical multilevel groundwater monitoring system has been developed that can be rapidly installed with a direct-push machine, yet is suitable for sampling across large permeability contrasts. This sealed multiport sampling (SMPS) system consists of up to five lengths of PVC tubing (12mm OD), each with a screen at a specific depth created by drilling 2.5-mm holes. Above and below each screen, round elastomer pieces, with peripheral holes (to clip in the sampling tubes) and a central hole (to hold a discontinuous piece of central tubing at the height of the screen), are emplaced. Cement-bentonite grout is injected via a tremie tube inserted through the discontinuous centre tube into each interval between the sampling screens. The elastomer pieces and central tube prevent grout from reaching the screened interval. A textile wrapped around the system holds the arrangement in place and at the same time serves to filter the groundwater at the level of the sampling screens. The SMPS system was tested at a tetrachloroethene (PCE) contaminated site. The seals effectively separated the sampling intervals even in heterogeneous formations. Furthermore, concentration profiles agreed well with a reference system. The system should be suitable for a wide range of hydrogeological conditions.
