Dear Kamrul

Just to clarify your question: do you mean

  1. What are the expected ranges of the amount of Nitrate, Nitrite and Ammonia typically to be found in general pond and canal water?

or

  1. What are the permissible ranges of the amount of Nitrate, Nitrite and Ammonia in general pond and canal water after discharging effluent or fertiliser run-off into pond/ canal water?

Please post your response as an answer to your original question.

Kind regards, Leigh

Thank you Leigh for your response. I would like to know expected ranges of the amount of Nitrate, Nitrite and Ammonia. One of our study showing some data where I am not sure those are correct or not. The data shows Ammonia: 0.5 mg/l, Nitrate: 44.3 mg/l and Nitrite: 0 mg/l. I need to verify the data.

Best regards Kamrul

For Pond water the expected range of Nitrate depends on the presence of contamination, but for natural ponds that would go from 0.2 mg/L to 100 mg/L, the limit for drinking water is set to 50 mg/L. The presence of nitrite and ammonia depends on the dissolved oxygen and the organic content of the pond. Ammonia should be around 0.05 mg/L to 1 mg/L, drinking water standard in UK is 0.5 mg/L. The nitrite values should be very low, I am not aware of ranges specifically for pond water, but in freshwater in general I have hardly ever detected nitrite.
