Frequently Asked Questions

How do I properly maintain my water well?

Small problems can often be identified by performing maintenance before they become costly, inconvenient situations. This is similar to performing routine maintenance on a motor vehicle. If you have the oil changed at specified intervals, the engine will operate reliably much longer than if you do not. Do not become stranded without water over the relatively small cost of an annual service call—the cost of a repair call could be much higher. At a minimum, wells should be evaluated annually by a licensed or certified water well systems professional.

What is an annual well inspection and why is it important?

A properly constructed and maintained household-supply well will provide you with many years of quality service. The National Ground Water Association recommends routine annual maintenance checks to ensure the proper operation of the well and prolong its years of service, as well as monitor the water quality.

Routine inspection of a water well system can help ensure it is operating properly, prolong its useful life, and protect your investment. Most importantly, inspections can protect your health by discovering issues that could result in water quality problems presenting a health risk.

How do I hire a water well service contractor?

Prior to selecting a water well contractor for a job, it is a good idea to obtain information about several contractors in the area before making a choice. Here are some considerations:

  • Is the contractor licensed by the state? (Not all states require licensing.)
  • Is the contractor certified through the National Ground Water Association? The highest level a contractor can achieve is MGWC (Master Groundwater Contractor), passing all specialty NGWA certification exams and a general exam.
  • Does the contractor submit well logs?
  • Does the contractor have adequate equipment in good condition to do the job?
  • Does the contractor have adequate liability and workers’ compensation insurance to protect you?
  • Is the contractor familiar with applicable health and safety codes?
  • What is the contractor’s reputation with previous customers?
  • Will the contractor furnish a written contract specifying the terms and conditions of the job?
  • Is the contractor a member of the National Ground Water Association? Does he have a current NGWA sticker on his truck? NGWA members support the industry, have access to new technology and improved approaches, are dedicated to quality of workmanship, and promote and protect the groundwater resource. They know their stuff and will work with you to get the job done right. You can contact the NGWA customer service department at (800) 551-7379 or our “Contractor Lookup” for a list of member contractors in your area.

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
