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.
According to Building Advisor, the cost for drilling a well and installing a septic system may be $20,000 or more, depending on the region where the well and septic are installed and depth of the well. Permits, licensing fees, soil testing and supplies are included in the cost estimate.
