If any additional free <br /> product accumulation occurs, it can be detected and removed in a timely manner. <br /> BC recommends delaying the installation of the planned extraction well and groundwater <br /> treatment system until additional groundwater sample(s) from monitoring well W-213 <br /> confirm the presence of hydrocarbons in the groundwater in the 74- to 88-foot interval. <br /> ' If you have any questions or comments, please contact me or Ms. Jeanne Wallberg at <br /> l (916) 444-0123. <br /> Very truly yours, <br /> t <br /> r BROWN AND CALDWELL <br /> AawrenceE.
