Hydrocarbons as Gasoline <br /> CLIENT: Foothill Engineering <br /> 12793 Paddy Creek Lane <br /> Lodi, CA 95240 <br /> Attn: Ervin Rifenburg <br /> Date Sampled: 10/19/98 <br /> Date Received. 10/20/98 <br /> Project Name : Vogue Cleaners Date Started. 10/23/98 <br /> Date Completed: 10/26/98 <br /> Sampled By: Don Tight/DEL-TECH <br /> Lab Report # : H8102002 <br /> Water samples from the monitoring wells at Vogue Cleaners were <br /> checked for Stoddard' s Solvent using purge and trap 8015m. MW-3S <br /> was positive while all other wells were below detectable limits . <br /> The volatile level in MW-3S was 515 ppb as Stoddard ' s Solvent and <br /> 887 ppb as TPH Gas. While the retention window matched that of <br /> Stoddard ' s Solvent, the level of BTEX and other unidentified <br /> peaks in the sample indicates some gasoline . It is this lab ' s <br /> opinion that both entities exist with the majority coming from <br /> Stoddard ' s Solvent . <br /> G ncy G�iy Lug'' lC) 2 <br /> Nadenweg <br /> Laboratory Director <br /> OFFICE (209) 667-5258 .
