Soil and Water Testing

FAQ: Where do I get my water tested?

The Soil, Water, Forage Analytical Laboratory on the OSU campus tests water for irrigation, livestock, and other general uses; SWFAL is not certified for drinking water tests. 

Visit www.soiltesting.okstate.edu  for more information. Contact your county Extension office for water sampling bottles, sampling instructions, and other information.

If you are testing your well for the first time or you have concerns about bacteria, pathogens, or general drinking water quality, you will want to find an ODEQ-accredited water testing lab.
