Interpret NDR model results

Hi, I am an NDR model user. After the model runs, I post a message to discuss the results.

From the model results, we calculated the purifying efficiency of N and P of city area 

It's about 76%.

I can not understand why the results efficiency is so high., so I want to get some advice from the natcap team.

If there is a similar study result or if you know why, please explain.

Thank you!
