Abstract:
A method of collecting samples that are not polluted at the outside of a borehole at a predetermined depth by using a multi-packer and an apparatus therefore. Contaminated water in the borehole between first and second packers of the multi-packer is selectively discharged into a contaminated water discharging vessel installed on a lower end of a sample collecting container by opening or closing an electronic switching valve in the contaminated water discharging vessel.
