IRN and Environmental Defense commissioned an independent review of the water quality assessment contained in the Nam Theun 2 Environmental Assessment and Management Plan (EAMP). The review found that the EAMP fails to accurately predict water quality impacts post–impoundment because it uses models calibrated with limited and insufficient data sets.

The problems inherent in the NT2 EAMP modeling approach are amplified by a trend toward a gross oversimplification of complex aquatic ecosystem structure and function. The Nam Theun 2 Project is ecologically unsound and will cause serious and irreversible environmental damage to the area.
