Ground conductivity
From Wikipedia, the free encyclopedia
Ground conductivity refers to the electrical conductivity of the subsurface of the earth.
Ground conductivity is an extremely important factor in determining the strength and field propagation of AM radio stations because of mediumwave's groundwave propagation.
It is sometimes used in determining the efficiency of a septic tank, using electromagnetic induction, so that contaminants do not reach the surface or nearby water supplies.[1]
