As an owner of a pest company since the late 70's, Chloridane (Chlorinated hydrocarbons) was only one type of these materials. This chemical family had what was termed a 25 year half life. Aldrin was probably one of the most long lasting of the bunch. Most of these products bonded to the soil and did not travel. A soil test would confirm it and what's present. That's pretty pricey.
