Temperature

Temperature of water collected from the sites vary largely.

This may be due to the collection of the water in sample bottles and it was not tested on the spot immediately. For example, the tap water was collected first and left untested for a length of time after it was collected.

This may have resulted in temperature fluctuations during that period of time. Thus, the temperature readings probably do not reflect their initial temperatures and are not accurate, causing the results to be varying.
