• Water well drilling machines are used to make an "engineered hole" through the soil and rock layers to reach groundwater.
• The cost of a modern drilling machine is about $500,000!
• Not all water wells are drilled the same way, but rotary drilling is the most common method.
• 6,000 New water wells are drilled in America every week.
• There are more than 15 million wells in use in America for individual homes and farms.
• Groundwater is the source of daily drinking water for nearly 150 million Americans.
• There are still nearly one million old-fashioned "dug wells" in use. These are very difficult to keep free from water quality problems. Deep drilled wells are much more reliable and provide safer drinking water.
