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.
For example, Cushing & Sons Well Drilling in New Hampshire estimates an average cost of $5,000 for a complete water well system in that area, while a Colorado landowner reports costs of $14,000 to drill a 600' well (about $23-$24/foot) and another $7,000-$8,000 for a constant pressure pump system with a 70' water line to the house, or $21,000-$22,000 total.
