While, there may be economic benefits <br />when CRA salinity is below 500 mg/L, this graph shows the "incremental" impacts of CRA <br />salinity compared to 500 mg/L. Historically, the average annual salinity of CRA has never <br />been below 500 mg/L. See Technical Appendix 5 for additional information on this analysis. <br />Technical Appendix 6 specifically addresses the high-profile issue of the impacts of water <br />softeners. <br /> <br />BOOKMAN-EDMONSTON Section 2 <br /> <br />ENGINEERING, INC. 2-23 Salinity Problems, Impacts, & Technology <br />O:\LOCALRES\ANDYS\SALINITY\JUNE98-3\6SECT2.DOC Last printed 08118/98 9:45 AM <br />
