1.6 Limitation of the Study
Assessing
the variability in leachate composition and leachate migration from old
landfills needs an integrated approach. Historical information
(including old maps, aerial photographs, interviews, etc.) creates a
valuable basis for understanding the variability. Also, information on
the hydrology of the dumpsite and the adjacent part of the polluted
aquifer is needed. Detailed information of the site like depth could not
be extracted from the appropriate authority due to the fact that the
sites were not originally planned and designed for the purpose of waste
management. As a result of proximity of the examined dumpsites, there
were problems of spatial boundary location. The Solous dumpsites are
interconnected and to establish surface hydrological boundary in between
them posed a very serious task. However, surface delineation of
landfill areas may not coincide with the underground water basin. Most
of the inhabitants refused to cooperate due to their suspicion that the
researcher was an agent to State Government set out to expose their
non-compliance with the instructions of the Lagos State Water
Corporation.
The lack of standard laboratories as well as the high
cost of testing each sample affected the number of samples tested. A
long distance was travelled to avail the services of the Lagos State
Environmental Protection Agency to test the water samples and soil
samples were tested out of state resulting in additional transport
costs. Period of observation, that is rainy season, might also checkmate
the results from the parameters.
1.7 Definition of Terms
Sustainable
Development: is the organizing principle for meeting human development
goals while at the same time sustaining the ability of natural systems
to provide the natural resources and ecosystem services upon which the
economy and society depend. The desired result is a state of society
where living conditions and resource use continue to meet human needs
without undermining the integrity and stability of the natural system.
Sustainable development can be classified as development that meet the
needs of the present without compromising the ability of future
generations
Dumpsites: Also known as traditional landfills are excavated pieces of land or pits where waste materials are stored.
Landfill: An old and easiest method of waste disposal that involves burying the waste in specially constructed sites.
Sanitary Landfill: A designed and engineered method of disposing of solid wastes to reduce groundwater pollution.
