s <br /> PUBLIC HEALTH <br /> SAN JOAQUIN COUNTY <br /> JOGI KHANNA M.D.,M.P.H. " '` <br /> Health Officer <br /> P.O.Box 2009 . (1601 East Hazelton Avenue) Stockton,California 95201 ��Fiy* <br /> (209) 468-3400 <br /> November 7, 1989 <br /> Angela M. Casazza C(apy <br /> c/o Claudio Dell 'Eva <br /> 530 Yale Street <br /> San Francisco, CA 94134 <br /> RE: Modesto Dry Ice, Inc. , 260 S. Main; Manteca, CA 95336. <br /> The Environmental Health Division has reviewed the Site Assessment Report <br /> submitted by Jim Thorpe Oil . We do not agree with the conclusions made by <br /> this contracting firm for the following reasons: <br /> 1 . Plans which contain engineering, geology, and/or geophysical <br /> interpretations must be prepared under the direction of properly <br /> licensed individuals in the State of California (Refer to the <br /> enclosed Sections 6735,7835, and 7835. 1 of California Business and <br /> Professions Code). Responsibility for the technical information <br /> is indicated by the signature and/or stamp of the seal of the <br /> licensed individual . More than one signature and/or seal may be <br /> required where more than one professional specialty is included in <br /> the technical document submitted. <br /> 2. Excavation procedures and soil/groundwater samplings that involve <br /> interpretation of collected data should be certified by a <br /> Registered Geologist, Certified Engineering Geologist, or <br /> Registered Engineer. <br /> 3. Site maps should illustrate the distribution (both lateral and <br /> vertical ) of the contaminants in the soil and groundwater. <br /> 4. The reference used for reported groundwater depth has not been <br /> included within the report. <br /> 5. The site stratigraphy has not been presented within the report. <br /> 6. Although an immediate source removal has taken place and residual <br /> soil contamination appears to be absent, we cannot agree with the <br /> conclusion that further site evaluation is not necessary. <br /> 7. Groundwater depths in this area of San Joaquin County have been <br /> measured to be 20-30 feet below surface. Initial re-excavation <br /> soil analysis results showed contamination present 10 feet below <br /> surface. Therefore, due to the proximity of groundwater, a <br /> groundwater investigation should be performed. <br /> A Division of San Joaquin County Health Care Services 0 <br />
