Key:  in each case "AA" is the highest level of water quality

  
 

TF is temperature Fahrenheit; TC is Temp. Centigrade; TV is the EPA's evaluation of that temperature -- colder the better.

  
 

pH is the measure of acidity; HV is the EPA's evaluation of that level --- 6.5 to 8.5 is AA.

  
 

DO is dissolved oxygen; DV is the EPA's evaluation of that level -- the higher the better, 10 is AA.

  
 

NS: Not Sampled

  
 

* Meter Reading, rather than standard quality tests

  
 

** Re-test due to extreme initial reading
