Directive No. HEW-77

As work on the Columbia Basin irrigation project on the Columbia River is in the initial stages, the question of the effect of this project of the mineral content of the Columbia River has been raised. As an increase in dissolved mineral matter would seem to be likely, it was felt that quantitative estimate of the magnitude of this increase would be important, specifically with reference to the retaining of the demineralization plant at 100-D Area. Accordingly, a study has been made of the probable effect of the irrigation project on the chemical characteristics of the Columbia River.
