The temporary casings which will be <br /> placed within the borehole for the purpose of collecting a groundwater sample shall be <br /> removed on the day of assessment and grouted using a tremmie pipe from the bottom up. <br /> Please contact me directly to schedule a grout inspection when the field activities have been <br /> scheduled with the C-57 license holder. <br /> I have also attached recent information which has been provided by the Central Valley <br /> Regional Water Quality Control Board dated July 18, 1997 regarding analysis for petroleum <br /> fuel oxygenates. Since your scope included MTBE, I thought this information would be of <br /> interest. <br />
