Research and down-hole camera investigations show that all wells will have some degree of bacterial growth, sediment build-up, encrustation, scaling and deterioration.  While disinfection of wells is required as part of the construction and alteration process, the following cleaning and disinfecting procedures are to be performed when there is a problem with continual positive or high bacterial colony counts, when a well that has not been in use for an extended period is being brought back into service, or when the integrity of the well has been compromised by flooding or physical damage to the well casing.  The procedure is intended to supplement and act as an instructive guide to performing the enhanced disinfectant process cited in rule 3701-28-11(H) of the Private Water Systems Rules, Chapter 3701-28 of the Ohio Administrative Code.
