A trend analysis was performed for <br /> each plotted COC and the time for the COC to reach the water quality objective (WQO) <br /> was calculated. A summary of the projected time to reach the WQO is presented below <br /> in Table A. <br /> Years <br /> Maximum Current Half- Date to to <br /> Well Analyte <br /> Concentration Concentration Life Reach reach <br /> (µg/L) (µg,/1.)
