The Mineral Quality Problem in the Colorado River Basin. Published by the U.S. Environmental Protection Agency, Regions VIII and IX (1971). 5
documents.
1—Summary Report (10 + 65 p.). Contents include an explanatory Preface (reprinted in Appendices); Introduction; Summary of Findings and
Recommendations; Description of Area; Mineral Quality Evaluation; Technical Possibilities for Salinity Control; Alternatives for Management and Control of
Salinity; Action for Salinity Control and Management; with nine tables and figures, maps. (From the recommendations: “It is recommended that … [a]
salinity policy be adopted for the Colorado River system that would have as its objective the maintenance of salinity concentrations at or below levels
presently found n the lower mainstem.”)
2—Appendix A: Natural and Man-Made Conditions Affecting Mineral Quality (x + 168 p.). Includes Introduction;
Factors which Affect Mineral Quality of Streams; Historic Changes in Water Quality; Nature, Location and Magnitude of Salinity Sources; Results of
Field Investigations (Upper Basin and Lower Basin); Summary of Findings for Entire Colorado River Basin; Bibliography; with Tables and
Figures.
3—Appendix B: Physical and Economic Impacts (xi + 166 p.). Includes introduction; Effects of Salinity on Beneficial Uses of Water (Consumptive and
Non-Consumptive); Present and Future Mineral Quality; Direct Penalty Cost Evaluation; Region-Wide Economic Impact; Conclusions; Bibliography; with Tables,
Figures and maps. Data provided for 1960 and projections for 1980 and 2010 (concentration of solids, mineral quality, completion date for projects,
projected use of Metropolitan Water District Water for Irrigated Agriculture, Summary of Direct Penalty Costs).
4—Appendix C: Salinity Control and
Management Aspects (vii + 135 p.). Includes Introduction; Mineral Quality Standards; Technical Responsibilities for Salinity Control; Status of Salinity
Control Activities; Alternatives for Management of Salinity; Economic Aspects; with Tables and Figures. (From the Introduction: “Salinity is one of the
most serious water quality problems in the Colorado River Basin. Like many streams in the arid West, the Colorado River displays a progressive increase
in salinity (total dissolved solids) between its headwaters and its mouth.”)
5—Appendix D: Comments on Draft Report (approximately 75 p.). Includes
written comments from officials of California, Colorado, Nevada, New Mexico, Utah, and Wyoming; and the Upper Colorado River Commission.
