摘要

System for in situ sampling of ground water comprises laying slightly sloping collecting pipes (4, 5, 6) at different levels in the formation. The collected water may be fed to an artificial or natural subterranean chamber or sampled directly by probes in bores at the ends of the collecting pipes.
