HISTORICAL TIME SERIES PLOTS AND STIFF DIAGRAMS <br /> Constituents not detected are plotted at a value of half their respective detection limits in the Historical <br /> Time Series Plots (Appendix F). Note that Outliers were included in the plots as directed by RWQCB <br /> staff. <br /> Stiff diagrams are submitted semi annually. The stiff diagrams submitted for the first semester indicate <br /> that well G-1 is a sodium-bicarbonate water type, whereas,the other wells do not show a prominent <br /> cation with a prominent anion of bicarbonate (Appendix F). The dissimilarity in diagram shapes may <br /> be an indication of natural regional changes in groundwater quality conditions. <br /> North County RC&SL Public Works/Solid Waste <br /> 2"d Semester and Annual 2012 Groundwater Monitoring 20 County of San Joaquin—January 15,2013 <br />
