In the north atlantic region, Virginia to Maine, yields of industrial and municipal wells are the most reliable indicators of the water - yielding potential of consolideted rocks. Generally, such wells represent efforts to develop a maximum supply of water, they are 350 to 500 feet deep an they utilize 60 to 150 feet of drawdown. In multiple well developments, average yields of wells per 100 feet of drawdown range from less than 75 gallons per minute in the least favorable rocks such as shale or granite gneiss to as much as 300 gallons per minute in limestone in any one rock type ... |
