Key: in each case "AA" is the highest level of water quality
TF is temperature Fahrenheit; 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.
