| Abstract;This paper explains the following items on the titled research: 1) Approach; Resistivity distribution at disposed material strata and ion concentration of its leachate were studied at four landfill sites with different service history, 2) results; Major ions found in leachate were Na+, K+, Cl-, Ca2+ and HCO3-, the former three being more soluble in water than Ca2+. HCO3- concentration is relatively high, however, may depend on landfilled waste material and subsurface conditions. Conductivity of leachate is almost controlled by concentrations of the oboe ions in water. Cross-sectional resistivity distribution well reflects structure and property of the strata. Natural replenishment decreases the above ion concentrations, leading to decrease in conductivity and 3) conclusion; Temporal change in resistivity is potential indicator of environmental change in deposited strata, due to close relation between conductivity of leachate and resistivity of strata. |
