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.
Is there any cost savings with a well vs. city water or other options? Yes there can be significant savings. The initial cost of a water well for a residence ranges between $4,500 & $10,000 depending on the depth of the well and size of the pumping system.
