The EPA (Environmental Protection Agency) recommends that drinking <br />water contain no more than 500 mg/L of total dissolved solids. <br /> <br />For irrigators. higher salt concentrations cause decreased crop yields, <br />altered crop patterns, increased leaching and drainage requirements, and <br />increased management costs. Agricultural losses (either through lower <br />yields or increased production/management costs) begin when salinity levels <br />of applied irrigation water reach 700 to 850 mg/L. depending upon soil <br />condi t ions and type of crop grown. A summary of the effects is presented <br />in table 1. <br /> <br />5 <br />
