. doza <br /> Mr. M. Phillip Car <br /> Cardoza Properties <br /> May 15, 1990 <br /> File: J-2062-1 <br /> Page 3 <br /> During drilling of borings B-5, B-6 and B-7 , we detected no <br /> evidence of gasoline within the upper 6. 5 feet of soil. Results <br /> of chemical testing indicate that all constituents of gasoline <br /> are below detection limits at boring locations B-5, B-6 and B-7 . <br /> CONCLUSIONS <br /> Based on the physical conditions of the original pipeline break <br /> (i . e. subsurface pipeline break and lateral migration of gasoline <br /> within groundwater via a dewatering well) , results of our sub- <br /> surface drilling and chemical test results by BCA it is our <br /> opinion that: <br /> 0 On-site soils have not been contaminated by the <br /> Chevron pipeline break. <br /> • On-site groundwater has been contaminated by the <br /> Chevron pipeline break. <br /> Based on my telephone conversations with Mr. Doug Christian of <br /> Chevron, it is my understanding that Chevron is independently <br /> pursuing a groundwater extraction and clean-up plan for this <br /> area. Such a program should not affect the planned development <br /> of Grant Line Plaza as Chevron's extraction/treatment wells can <br /> be located off-site or if on-site can be located outside of the <br /> building footprints. <br /> I trust this information meets your present needs.
