The stink usually is enough to warn you about these issues, but people including yourself, whom I assume is well educated, need to be better informed of environmental issues regarding condensate. We wave a red flag like the man walking in front of the first Cars, creates awareness that a dangerous change in water use is in progress, and responsible management is required.
