Abstract

This study has been prepared to clarify the environmental impacts of irregular solid waste disposal sites in Duzce. Solid wastes were found in the Melen dam basin, where the drinking water of the Istanbul metropolitan area was provided and poured on the edge of the Kucuk Melen Stream and on alluvium without taking any precautions. Geological and hydrogeological maps of solid waste irregular disposal sites and its surroundings are prepared. In order to determine the groundwater quality in the study area chemical analysis results determined for potability and various usability purposes. The hydraulic connection between the surface and groundwater of irregular solid waste disposal site was evaluated under different environmental conditions and conceptual models were prepared. It has been determined that the solid waste irregular storage site in the study area negatively affects the surface and groundwater quality and the water samples are not suitable for human consumption purposes. As a result, transportation of solid wastes in the drinking water basin from the region to a regular solid waste storage facility or construction of a 45 m deep all-around impermeability curtain has been seen as secure solution methods. Furthermore, in the condition of the leak water level in the environment which is isolated from the surface water and groundwater is below the natural water level, it will have been prevented the water flow out of the storage facility.

Highlights

In our country, solid wastes are collected under the ‘Regulation on Control of Solid Wastes’ and the obligations for recycling are fulfilled in a way that will create a negative impact on the environment and human health

Summary

Introduction

Solid wastes are collected under the ‘Regulation on Control of Solid Wastes’ and the obligations for recycling are fulfilled in a way that will create a negative impact on the environment and human health. Solid waste collected across the country is disposed of as %6 by recycling method, as 64% by regular landfill method and as 30% by solid waste irregular storage method [2]. The legislation related to these issues in Turkey, the negative environmental impacts of irregular solid waste storage sites from past years to the present are continuing. This study aims to propose potential solutions for the determination and improvement of the impact of the solid waste irregular dump site on water sources in the Melen Dam Lake Basin, which is planned to be supplied with drinking water to Istanbul. The solid waste irregular storage site is located on the right bank of the Küçük Melen Stream in the Düzce plain and spreads over an area of approximately 184 m2 (Figure 1)
