Agricultural spray drift (non-target) from the nearest agricultural production land affecting the property would be extremely remote also due to the distances involved. Since the Stockton region has been, and continues to be intensely farmed, nitrate contamination of the underlying groundwater from fertilization is always a possibility. Salt intrusion from the Delta can also be considered a potential problem for the public water supply. § 3.5 Description of all current off-site potential and/or known above and below ground sources of contamination identified in the area of the project site include those sites referenced in Section 3.4 above. These listed sites can be considered"past"off-site sources of contamination that are simultaneously"current" contaminated sources. § 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 in the above Sections have been discussed in the respective Sections to facilitate the transfer of information to the reader. § 5.0 CONCLUSIONS AND RECOMMENDATIONS § 5.1 Evaluation of each point source potential contamination described (i.e., the two LUST Sites, the Marley Cooling Tower RCRA Site, lead paint and asbestos, and de minimus items such as fuel cans, etc.) and non-point sources (i.e., agrichemical application and non-target drift, nitrate and salt in the underlying groundwater, and possible DDT soil concentrations) pose a very low-to-insignificant risk to the subject property. It is improbable that any of the listed sites, or non-point sources (other than nitrate and salt) could affect groundwater under the subject property. If there is contamination under the property from the Marley Site, the contamination source has been well-documented. The ASTM E-1527-00 Document referenced on Page 2 refers to de minimus environmental conditions. De minimus conditions generally do not present a material risk to public health or to the environment and generally would not include an enforcement action if observed by the appropriate governmental agencies. Household hazardous materials may be considered de minimus concerns if there has been no spillage or dumping. Typical household "hazardous materials" include gasoline, paint thinners,new and used motor oil, antifreeze, etc. Spillage or dumping of hazardous substances was not noted in the areas observed on the subject property. Nor was there any hazardous materials observed next to the property, as best as could be determined. It is noted in the Environmental Questionnaire that there was apparently never an above ground or underground storage tank on the property. Page -5- Chesney Consulting
