The sum of the anions and cations measured from this sample are 88 meq /L and <br />83 meq /L respectively. Conductivity (6,330 umhos /cm) and total alkalinity (1,250 mg /L) <br />were both representative of historical values and below EWI range. The values for all <br />other indicator parameters analyzed were below the EWI levels showing no marked <br />corresponding increase. Data validation and QA /QC samples indicate no apparent <br />laboratory or sampling issues. Monitoring of up- gradient alluvial well 28 -1 will continue <br />on a quarterly frequency. <br />
