Abstract
Groundwater contamination by agricultural chemicals is getting one of the most serious environmental problems, especially in golf course. This study focuses on the infiltration and dispersion of pesticides (MEP) with rainfall on the patting-green in golf course.
In order to estimate both the hydraulic characteristics of groundwater and the concentration distribution of scattered pesticides in the ground, the experimental research is carried out with sand-layer column models. Experimental data of tensiometers and thermometers are estimated by hydraulic analysis and test samples of polluted water are chemically analyzed by the method of gaschromatography (FTD).
Main results obtained are as follows: 1) values of tensiometer do not change under such rainfall condition as less than or equalto 20 mm/hr intensity and 20 min duration time, except the surface layer and 2) most of the scattered pesticides are adsorbed by the grass and soil particles and therefore the amounts which flow out into the groundwater are very little.
