According the data, the site is pending a decline in concentrations. However, <br /> AGE cannot state when the groundwater contamination and more over the TPH-g <br /> concentration will achieve a concentration of 5 micrograms per liter or lower, nor when <br /> groundwater will be a concentration of 0.5 ug/I for benzene. <br /> Thank you in advance for your help in this matter. Please call me if you have any questions. <br /> Sincerely, <br /> William R.
