Frequently Asked Questions

What is a drilled well?

A drilled well consists of a hole bored (a borehole) into the ground, with the upper part or the entire depth of the well being lined with casing. Drilling is most typically conducted with a portable drilling machine brought to the site to construct the borehole. Various methods are used to advance the borehole to the necessary depth, and to remove formation material loosened and suspended by the drilling bit and fluid circulation or bailing system.

Does water well drilling require a license?

In the United States, most states require licensing of water well contractors, and in most cases, this means that licensed contractors have passed tests and met certain professional requirements to obtain their license. Canadian provinces, Australian states, and New Zealand also use qualification-based licensing. To find out if a contractor is licensed, contact your state government (licensing is often handled by the Department of Natural Resources or Department of Health).

To achieve NGWA certification, contractors must pass exams testing their technical knowledge, and they must have at least twenty-four consecutive months of full-time groundwater contracting experience. They maintain their certification by obtaining continuing education credits annually.

California Groundwater and Water Well Statistics

Few states can accurately or confidentially determine how many residential wells are in place. For each region, the American Housing Survey by the U.S. Census provides regional data.

California is found in the West, along with these other states: Alaska, Hawaii, Washington, Oregon, California, Idaho, Utah, Nevada, Arizona, New Mexico, Colorado, Wyoming, and Montana.

The last American Housing Survey Census indicates this region had 1,540,0002 households served by residential wells, with an average of 2.973 persons per household. The USGS estimates the population of self-supplied water supply users in California to be 1,440,000 for which groundwater is 85% of their water source.

  • 2,081 community water systems use groundwater for 7,286,000 people
  • 1,393 non-community, non-transient water systems use groundwater for 371,400 people
  • 2,874 non-community, transient water systems use groundwater for 603,200 people
  • 59,500 irrigation wells used serving 23,600 farms and 3,860,000 acres
