Disinfection procedures for abandoning wells
 

What is the justification for using chlorine to abandon wells. If disinfection of water in the void space of the well is critical, why would it also not be required to do a disinfection of the water in the annular space prior to a grout of a well. I don't understand the public health significance of disinfecting water that will not be consumed by people. If you disinfect the water then put "clean fill" in the well that is full of pathogens and bacteria, what was accomplished? 

Also based of the new procedures the WSSP will need to disinfect the well, sample and test chlorine levels and wait 5 to 24 hours prior to abandoning the well. Is this the intent now? I think this would increase cost of the abandonment while providing no additional public health benefit.
