In the EPA report that has already been produced the conclusions stated:

However, chemical and microbiological sampling of the water in the sumps and ponded water over the winter periods showed improved water quality, equivalent to surface runoff from the other systems that had not been fed any effluent

If the runoff was equal to areas with no effluent, that suggests there is already E. coli in the groundwater. In other words, dirty water is being compared with dirty water rather than clean water. Does Dr. Ryan get where I am coming from? It seems the EPA is, in that sense, trying to achieve something that is not achievable, or is that an incorrect conclusion to draw?
