Wells that are aban­doned shall be sealed in a man­ner pre­scribed by the Health Author­i­ty and the “Illi­nois Water Well Con­struc­tion Code”.  The Health Author­i­ty shall inspect aban­doned wells which have been sealed to deter­mine com­pli­ance with these reg­u­la­tions.  In ques­tion­able cas­es, the Health Author­i­ty shall make the deter­mi­na­tion as to whether a water well is con­sid­ered aban­doned, based upon the def­i­n­i­tion of an “aban­doned well” and the facts in each par­tic­u­lar case.
