Effects on Groundwater Flow and Groundwater Quality of a Waste Disposal Site in Noordwijk, the Netherlands

Improper dump sites have served many years as an ultimate disposal site for all types of waste; municipal solid waste, industrial sewage and hazardous waste in developing countries such as Ethiopia. Physical, chemical and biological processes interact simultaneously to bring about the overall decomposition of the wastes (chemically laden leachate). If not, deal properly, such kind of dumping site can cause pollution to groundwater (because of Leachates) and surface water (through contaminant transportation by flooding and groundwater movements). Therefore, this study investigates the spatial and temporal variation of groundwater quality within the Chilanchil Abay watershed during dry and wet season due to the waste disposal site of the Bahir Dar city. Water samples were collected from 6 sampling points of groundwater from 30th March to 20th August by a monthly period. Over 10 water quality parameters such as pH, TDS, Electrical conductivity, Turbidity, Temperature, DO, BOD, COD, TC, NO3- and PO43–, were analyzed. Moreover, the overall status of the groundwater quality of the study area was evaluated by the Canadian Water Quality Index. Based on the result of this model the status of the groundwater sample points throughout the study area were raged from 42 to 46.2 (marginal status).

A waste disposal site to be constructed in a coastal area is generally surrounded by seawall structures to accommodate waste reclaimed. In case that the seawalls are required to prevent substances contained in waste from leaking out to the sea, they are constructed as quasi-impermeable structures. The quasi-impermeability of the structures is required to be retained by self-sealing performance even in their deformed conditions to be possibly caused by deformation of soft ground or actions of earthquake, wave, tide etc. In addition, it is preferable for quasi-impermeable material to have the features of long durability and adjustability in its fabrication to suit for various construction conditions. We have developed a new quasi-impermeable material with the features of self-sealing, long durability and adjustability in its fabrication by main use of dredged marine clay taking advantage of its low impermeability. In the relevant standard of ministerial ordinance, quasi-impermeable seawall structures are required to have the thickness of 0.5m or more and equivalent hydraulic conductivity of 1.0×10−8 m/s or less. In this study, proposed is a quasi-impermeable seawall structure with steel frame by jointing H-steel sheet piles and such clayey quasi-impermeable material filled inside the frame. The overall performance of the proposed structure was examined in a field test exposing it to a natural sea condition for more than one year. The self-sealing performance of the structure was also examined in the test after intentionally deforming it. Regarding the quality of filling clayey material, the homogeneity of filling was investigated by sounding and sampling tests. It has been confirmed that the structure realizes quasi-impermeability with equivalent hydraulic conductivity of the order of ke = 10−9 m/s, which satisfies the design criteria prescribed by a ministerial ordinance in Japan to allow for practical use in the sea.

The paper identifies the causes of contamination and analyses changes in the quality of underground water resources at the Dobra intake, which supplies water for a separated group of Jaworzno inhabitants. The analysis takes into consideration such aspects as land conditions and their influence on physicochemical changes of water taken in in relation to the effective legal requirements for potable water. Moreover, an integral part of analysis of potential threats was an assessment of the effect of closed municipal waste disposal site and mining activity on the quantitative and qualitative resources of underground water in the area supplied by the Dobra intake in Jaworzno.
