MODELING OF CONTAMINATION TRANSPORT RELEASED FROM OLD MUNICIPAL SOLID WASTE LANDFILL SITE: A CASE STUDY, SOUTHERN POLAND

Sławomir Sitek

Abstract

The municipal solid waste landfill in Tychy, southern Poland consists of three sites, the old one, closed in 1994, and two others still being in use. The old part of the landfill has neither any bottom liner nor any leachate collection and treatment system. Moreover, the bottom of the closed site in the northern part is continuously above the groundwater table, therefore, pollution can easily release into groundwater causing deterioration of groundwater quality and the nearby river nearby. In order to assess the impact and fate of the pollution in groundwater environment and to estimate the spatial size of the contamination plume in the Quaternary sandy aquifer, the transient transport model was designed based on the steady-state flow model, calibrated for the year 2016. Boron was chosen for single-species transient mass transport model. The obtained results indicate that the contamination plume migrates towards the Gostynia river along the main groundwater flow direction. The highest concentration of boron, about 20 mg/dm3, is recorded at the northern part of the landfill site. The contamination plume migrating to the south quickly dilutes reaching the boron concentration lower than 2 mg/dm3 in groundwater close to the Gostynia river. The size of the pollution plume reaches about 1,100 m in length and an average of 225 m in width. With the assumed supply of pollutants to the aquifer at the level of 2016, the amount of boron washed-out from the old landfill site entering the Gostynia river within 20 years will be about 1.4 tons.
