Well Driller List

State rules

Mississippi

Mississippi licenses drillers and pump installers through the Department of Environmental Quality, Office of Land and Water Resources. The office's water well drillers page says it licenses and regulates all drillers and pump installers operating in the state. A person who wants to contract for water wells files an application for a water well driller's license. A restricted driller's license is available for drilling that is not a water supply well, and it is valid only for the stated purpose. Pump installers file for a pump installer's license. The page says a well driller licensed in Mississippi must be used to drill water wells. The office keeps a current list of licensees. This record does not copy that list.

The page says licensees must show competency by passing tests given by the office or by the National Groundwater Association. The office also keeps records of drilled and plugged wells and holes and enforces the regulations that protect groundwater. Companies that install or service pumps must have an individual license holder who certifies the competency of the company's installers. The page says water well drillers must register their drilling rigs with the office. Those are the public conditions a customer can ask about: the individual license, the test, and the rig registration.

A restricted license is not a substitute for a water well driller's license when the hole is a water supply well. The page draws that line by saying the restricted license is valid only for the specified drilling purpose. Someone hiring a firm for a drinking-water well should ask for the water well driller license, not a restricted or monitoring-only credential, unless the office has confirmed that the restricted class covers the work. Pump work is a separate license. A company can have installers, but the page says an individual license holder is responsible for certifying their competency.

The same office maintains the well records that show what was drilled or plugged. Asking for the record that will be filed is as important as asking for the license. The department's page is the place to find the current licensee list and the rig registration form. This record does not name drillers and does not copy a fee into the fee field. Readers who need the dollar amount should read it on the department's current page rather than from a secondary summary. The requirement to use a Mississippi-licensed driller for a water well is the point the page states most directly.

What to do next

  1. Ask for a water well driller license, not only a restricted license.
  2. Ask which person is the licensed pump installer if the pump is a separate contract.
  3. Ask for the rig registration if the firm will drill.
  4. Use MDEQ's licensee list rather than a copied roster.
