The variance in cost-effectiveness, according to <br />the BOR Salinity Control Program Coordinator, stems from many things, <br />such as the number and type of activities involved (as shown in table 1), <br />the size and complexity of the project, and advances in technology (e.g., <br /> <br />Page 12 <br /> <br />GAOIRCED-9G-58 Salinity Control Projects in the Colorado River Basin <br />
