Ammonium Test

1. Draw a line 5 mm from the top of the cuvette.

1. (Continued) Begin with the Local Community Treated Water sample and pour the sample up to the marked line.

2. Dip one Ammonia Reagent Strip into the Sample for 40 seconds with a gentle, steady, up and down motion. 3. Remove and discard the strip.

3. Pour the 4 mL of AEUL from the vial into the other cuvette.

4. Dip one Ammonia Reagent Strip into the AEUL for 40 seconds with a gentle, steady, up and down motion. 5. Remove and discard the strip.

6. After 5 minutes, match the colour by placing the vial on the white circles on the card. Look into the top of the vial to see which colour matches best. A colour change from yellow (< 0.1 mg/L) to shades of green indicates the presence of ammonia. Use the colour chart to determine the ammonia concentration. Results: Since there is no Canadian Drinking Water Guideline for Ammonia you will compare results to the European Union limit. The standard should give a result very close to the 0.5 mg/L AEUL; if the colour is darker then it DOES NOT meet the guidelines.
