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 Wellwaterconnection.com, the cost of installing an irrigation well can range from $4,000 to $10,000. The average customer can save between $1,000 and $3,000 a year on water/sewage expenses resulting from using irrigation wells instead of relying on regular water supply. At Bobvila.com, an irrigation well costs around $3,000 to drill.
