Abstract

The study parameters: pH, conductivity, salinity, Total Dissolved Solids (TDS), Turbidity, Total Suspended Solids (TSS) and Chemical Oxygen Demand (COD) of groundwater in a closed industrial landfill, subject to the waste discharges of city of Bacau (East Romania), shows that the water quality of the different sampling points is variable. This difference is noted at the level of conductivity, TDS, turbidity, TSS and COD. These differences, however parameters are substantially higher compared the value of the legislation in groundwater Romania. Salinity remains relatively high at the point of sample P1 (0.7). The pH values are comprising in the range of reference values (6.5 to 7.4). The results also showed very strong correlations (r&gt; 0.8) between Conductivity-Salinity, Conductivity -TDS, Salinity, TDS, Turbidity.-TSS, COD and TSS-Turbidity-COD. The strong correlation (0.5 &lt;r&gt; 0.8) were noted between Turbidity- Conductivity, Turbidity-Salinity, Turbidity, TDS, TSS conductivity, TSS-Salinity, TSS, TDS, COD, conductivity, salinity, COD, COD-TDS. Principal Component Analysis (PCA) also highlighted groundwater mineralization events of this landfill and possible pollution by organic matter

Highlights

Rapid urbanization creates big quantities of waste in large cities
Physical and chemical parameters of water The pH of the water is slightly alkaline at four sampling points of the site
At point P1, the pH is slightly acidic (6.95). It varies between 6.95 and 7.44 at point P1 to point P3 to an average of 7.25 (Figure 4). The values of this parameter are in the range of pH values tolerated (6.5 to 7.4) for water aquifers by Romania [9]

Summary

Introduction

Rapid urbanization creates big quantities of waste in large cities. These wastes consist primarily of household waste, industrial waste, medical waste, sewage sludge etc. The strategy of prevention and reduction of environmental pollution through waste management through industrial discharge This form of management creates an indirect pollution of groundwater through precipitation, seepage or leakage of pollutants [1,2,3]. An obvious alternative method of controlling the pollution of groundwater by industrial discharges is to retrieve these water discharges through underground channels Such methods of storage of groundwater discharges may limit problems concerning water pollution and in some cases could create secondary benefits such as restoration of groundwater and decreased soil pollution [1]. Waste can often contain pathogens responsible for diseases [6]
