Thank you for your query. Sorry for the delay in replying.
The symptoms that you describe are very unlikely to be due to bad water. The first symtoms that you get due to bad water is vomiting
. In case you have been having diarrhoea and vomiting then the fatigue, tiredness
can be explained.
If the area is hot and humid then you may be sweating a lot which can give rise to all the symptoms that you have enumerated.
I hope I have responded to your query to your satisfaction.
