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.
Q: How much will it cost the plug my abandoned well? A: Costs vary depending upon the well depth, diameter, location, and other factors. A shallow driven well may be plugged for as little as $50. The average cost for plugging a well in Michigan is $500. Your costs may be reduced by having your old well plugged at the time the replacement well is drilled or at the time you connect to municipal water service.
