3.3 Description of All Current On -Site Potential and/or Known Above and Below Ground Sources of Contamination Identified at the Project Site: Presently, there are no underground storage tanks on the property and visual inspection did not produce any evidence of buried containers, as well as no odors that would be associated with buried chemical tanks. County records indicated there were no fuel tanks on site. There are no above ground fuel tanks on the site. On- site water dissipates through either percolation or evaporation. 3.4 Description of All Past Off -Site Potential and/or Known Above and Below Ground Sources of Contamination Identified In the Area of the Project Site: Past off-site potential for contamination is low. The subject parcel is in a residential neighborhood. The land use has historically been residential and not changed significantly. There was possible diesel contamination in the soil at 1701 W Washington Street (Stockton Fire Station #1), roughly 1000 linear feet northeast of the project site. However, the cleanup was filed complete by San Joaquin County as of 1999. 3.5 Description of all Present Off -Site Potential and/or Known Above and Below Ground Sources of Contamination Identified in the Area of the Project Site: Present off-site potential for contamination is low. (See Appendix for case studies.) 4.0 EVALUATION OF PAST AND CURRENT SOURCES OF CONTAMINATION IDENTIFIED AT OR NEAR THE SITE AND RECOMMENDATIONS FOR FURTHER ACTION: 4.1 Evaluation of each potential and/or known source of contamination identified for any real and/or potential threat to human health and the environment: The depth to ground water in this area is approximately 20 feet. This shallow depth to ground water might be a concern for contamination if this were in a heavily agricultural area with frequent chemical use. In this case the given area is, and historically has been a residential neighborhood. 5.0 CONCLUSIONS AND RECOMMENDATIONS SECTION: 5.1 Discussion of the Above Evaluation: There are no chemical containers or fuel storage tanks on this site, thus the potential for contamination is low. There are no commercial pesticides, insecticides, or fertilizers used on the site. No mitigation measures are recommended. 5.2 The Report is inclusive: All information in this report does not reference any other documents that are not contained in this report. 5.3 Report was signed dated and stamped: See below. 5.4 The report was prepared within Six Months of the Date of the Submittal: This report was originally generated in January of 2022. 5.5 The Attachment/Appendices Contain Sufficient Documentation to Support Claims Made in Report: See Appendix.
