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.
On average, a complete water well and pump system is $5,500 to $9,500. Variables are: depth to bedrock, depth to water, excavation requirements, and potential needs for treatment. We offer on-site, no-cost estimates. Here is a breakdown of items that may be included in the cost of a water well system: 1  Permits. 2  Mobilization (getting equipment to the site). 3  Drilling per foot by diameter. 4  Casing per foot and weight per foot. 5  Materials such as screens, seals, etc. 6  Grouting and cementing seals. 7  Developing.
