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.
When asking for a well drilling cost or estimate you will be given a standard price, one for drilling and one for the cost of steel casing. Currently on Vancouver Island, British Columbia.... the cost of drilling a well will roughly be $20.00 per foot for drilling and $20.00 per foot for casing. new water well drilling rig can be worth upwards to a million dollars fully equipped, there's additional equipment involved too, the cost of operating water well drilling equipment is high. Wages will be paid to normally one journeyman water well driller per rig.
