Units
Reporting proper units is every bit as important as reporting the correct
value. As an example, when reporting water temperature, there is a big difference
between 10 F and 10 C. The former is below freezing and the latter is roughly
42 F.
Most of the chemical tests will be presented in the units of mg/L. It is also
important to specify the chemical constituent you collected data on.
Some Common Units for Water Pollution Tests:
Dissolved Oxygen: mg/L DO
Nitrate Nitrogen: mg/L NO3
Ammonia Nitrogen: mg/L NH3
Chlorine: mg/L Cl2
Alkalinity: mg/L CaCO3
Phosphorus: mg/L PO4
Units of Other Tests:
Turbidity: NTU
Dissolved Oxygen- Percent Saturation: % DO
