LNLEEDSHILL•HERKENHOFF, INC. <br /> completed using handriven sampling techniques. After sample collection, <br /> these holes will be completely backfilled with a neat cement mixture. Since <br /> the total depth of sampling is less than ten feet, the OD of the hole is 1.5 <br /> inches, and a monitoring well is not to be constructed at this site, we <br /> request that the County waive the requirement that a C-57 licensed welldriller be required to use this specialized sampling equipment. <br /> If you have any questions please contact either Cynthia Wetmore or myself at <br /> 415/243-9980. Your prompt attention to this matter is greatly appreciated. <br /> Very truly yours, <br /> C� �wJE� i j�rr 41 o <br /> Gerry S.
