Variable General Info
Potential average mass nitrate removal ?Comment:Results are for the potential AVERAGE mass nitrate removal for the period 1990-1999. The minimum estimate is based on the more conservative scenario of the loss rate coefficient, and the maximum estimate is based on the less conservative scenario of the loss rate coefficient. The mean estimate is based on an average scenario of the loss rate coefficient. |
