Ask the manager of the water supply about the claims made by the caller
This is done.
The manager explains that a lab report had in fact flagged some problems with water quality on samples taken May 15, but that these samples were taken from a water-main construction site. The implication is that this was an isolated incident caused by the construction and that there have been no other negative results.
Is the manager telling the whole truth? Or is he trying to cover up something? Is the anonymous caller referring to this one negative report, or does he know about something bigger? Who should be believed?
Perhaps you'd better
