Yugi,
It is never late to correct a mistake.
Please come clean and admit that you did make a mistake when you stated that Berbicians drank boiled trench water during the 70's and 80's. Probably this was done prior to the 70's but definitely not during the 70's and 80's.
The area that I am from, Corriverton had portable drinking water at that time with two wells one at Springlands and one at Kingston and if Iam not mistaken there was another well at Line Path. In Crab wood Creek there was a well and along the coast there were several wells. Tjime and agin there used to be breakages at the wells but no one I knew drank trench water.
Yugi, time and again I have recognized that some of the things you do say are based on facts however in this instance you erred.
