I'm looking for an airborne effluent dispersion or dose model that will model deposition onto surface water. Currently using GENII which does NOT do this. If you are familiar with the following codes (or know of another) that I can use, please contact me. XOQDOQ MESODIF CAP-88 ORION etc. Joel I. Cehn, 800-227-2840 x234 JCehn@worldnet.att.net
