The marginal value of water for dilution of waste is observed to be small when computed on either a long run or a short run basis. A policy of clean water places a low marginal value on dilution water since these values increase in many situations with any increase in allowable concentration of waste in the receiving water. The marginal value of waters used to dilute saline irrigation return flows is generally higher than those used to dilute oxygen demanding wastes because of the relative currently higher salt removal treatment costs and the much higher allowable receiving water concentration for most salts.
