Good <br />quality groundwater (less than 250 mg/L) and low urban salt additions to wastewater (less <br />than 250 mg/L) were excluded from the analysis. <br /> <br />BOOKMAN-EDMONSTON Section 2 <br /> <br />EN GIN E E R I N G, I N C. 2-18 Salinity Problems, Impacts, & Technology <br />O:\LOCALRES\ANDYS\SALINITY'JUNE98-2\6SECTI.DOC Last printed 07/20198 10: 17 AM <br /> <br />. <br /> <br /> <br /> <br /> <br /> <br /> <br />. <br /> <br />. <br />
