I think the reason for all the contamination is the Health Departments ability to hang on to their jobs among other things. How many people do you hear about dying of Coloform bacteria ingestation?

I think you will find the reason for the elevated levels of bacteria is the fact that everyone used black or galvanized pipe for many years, the population boomed and now these old wells casings are full of holes. The surface water is getting into the casing from above. The new wells are practically all PVC now, so if seismic fluctuations don't break them, water certainly won't rust them through.
