*ftafl *Awe <br /> October 14,2004 <br /> NOA Project Number: E04112A <br /> 4.0 EVALUATION OF IDENTIFIED CONTAMINATION SOURCES <br /> There is no reason to believe that the threat to the subject property from the historic dairy is any greater <br /> than that posed to all properties in the area. <br /> From the information available at the EHD,it was not possible to determine whether the nearby drug <br /> lab cases may have impacted groundwater beneath the subject property,though it does not seem likely <br /> due to their distance from the property. <br /> The empty drum and other debris adjacent to the subject property do not appear to pose an immediate <br /> threat to the property. <br /> 5.0 CONCLUSIONS AND RECOMMENDATIONS <br /> WSW <br /> The debris identified on the subject property should be removed from the site and disposed of in <br /> accordance with all applicable laws and regulations. <br /> Given the likely historical use of agricultural chemicals on the subject property,meaningful conclusions <br /> regarding the presence or extent of such material cannot be determined without soil sampling and <br /> analysis. <br /> Should new construction require the development of domestic wells, EHD should be contacted for <br /> direction regarding possible impacts to groundwater from the agricultural history of the vicinity and the <br /> nearby drug lab case. <br /> •• If Mr.Huerta or the EHD are concerned about potential nitrate problems on the subject property from <br /> its past use as a hog farm,a soil sample from the vicinity of the former structures could be collected and <br /> analyzed to determine soil quality. <br /> • <br /> The debris pile at the southwest corner of the subject property should be periodically monitored to <br /> insure that no hazardous substances which could potentially impact the property are disposed at that <br /> �+ location. <br /> If any suspect or hazardous materials are identified during site grading or development,those materials <br /> `• should be removed from the site and disposed in accordance with all applicable laws and regulations. <br /> 6.0 LIMITATIONS <br /> This report was compiled as a Surface/Subsurface Contamination Report for the subject property. This <br /> report contains information and data provided to NOA by several sources. NOA in no way warrants , <br /> ... the accuracy or completeness of the information provided to this investigation by those sources. 01 <br /> 9 <br />
