Founder Effect. The Founder Effect is defined as a type of bottleneck, a type of genetic drift describing the loss of the allelic variation that accompanies founding of a new population from a very small number of individuals (a small sample of a much larger source population).
For example, two well drilling companies -- one in Pennsylvania and one that covers New Hampshire, Vermont and central Massachusetts -- state the cost for drilling a well and outfitting it with pump equipment averages between $5,000 and $7,000, at the time of publication.
The most common method of well construction in the United States today is drilling, which requires a fairly complicated and expensive drill rig, usually mounted on a large truck. Drilled wells are typically 100'-400' deep but can be 1,000' or more. complete submersible system will cost about $5500. An 80 ft 2 well alone will cost around $1000. A deep well & pump system drilled 500-600 ft deep costs about $10,000.
