<br />. <br /> <br />. <br /> <br />Salt loading occurs as a result of weathering and dissolution of the <br /> <br /> <br />soluble salts in soil and substrata. In addition, salt concentration <br /> <br />occurs due to the consumptive use, e.g., agricultural or industrial <br /> <br />applications, of the water in the basin. Generally, the application <br /> <br />of irrigation water results in increased salt concentrations because <br /> <br />of both loading and consumptive use. The salt load fluctuates annually <br /> <br /> <br />with the overall basin water supply. Without management as the states <br /> <br />continue to develop their compact-apportioned waters, the river's <br /> <br />salinity at Imperial Dam is projected to follow the overall rising <br />trend shown in the following illustration. <br /> <br />1100 <br /> <br />~ 1000 <br />...... <br />~ <br />::E: <br /> <br />......x- <br />'1.".:1- <br />y,/ <br />'(/ <br />/ <br />/1 <br />X <br />t/ 0"'-0 <br /> <br />~ <br /> <br />~ 900 <br />- <br />-' <br />o <br />Vl <br />C <br />L.I.J <br />> <br />-' <br />o <br />Vl <br />Vl <br />- <br />C <br /> <br /> <br /> <br />879 mg/L <br /> <br />800 <br /> <br />700 <br /> <br /> <br />Historical <br />---x---y,-- W/O WQIP <br /> <br />---0---0-- W/WQIP <br /> <br />-' <br /><2; <br />I- <br />o <br />I- <br /> <br />600 <br /> <br />500 <br /> <br />1940 <br /> <br />1950 <br /> <br />1960 <br /> <br />1970 <br /> <br />1980 <br /> <br />1990 <br /> <br />2000 <br /> <br />2010 <br /> <br />In response to the Federal Water Pollution Control Act (P.L, 92-500), <br /> <br />the Colorado River Basin states adopted salinity control standards for <br /> <br />the Colorado River.
