Flood instructions available for private wells
What should private well owners do when a well is flooded? Follow the guidelines outlined on the Iowa Department of Natural Resources (IDNR) website. According to IDNR, “Any well that has been influenced by flood waters requires professional assessment, necessary cleaning and repairs, chlorination, and finally water quality testing that proves it’s safe to drink before it should be used again.”
For well water sampling, testing and guidance, contact your local county health department to take advantage of free testing through their Grants-to-Counties program.
If you wish the State Hygienic Laboratory to send a water collection container directly to you for a fee (to evaluate if the shock chlorination was effective; or if flood waters were close to the well and you want to evaluate if the well was compromised), order a container by completing the Order a Water Sampling Kit form. Please state your reason for testing in the comment section and we will send the containers that you need. Remember, if flood water has covered your well, it is advised to contact a certified well contractor to assess, repair and perform shock chlorination BEFORE testing.
