October 11,2005 <br /> NOA Project Number: E05111A <br /> 4.0 EVALUATION OF IDENTIFIED CONTAMINATION SOURCES <br /> Agricultural chemical residues may remain on the property. No evidence was found, however, to <br /> indicate that the chemicals were applied inappropriately. A diesel fuel storage tank existed on the <br /> property, but has since been removed. No staining was observed in the location that the tank once <br /> existed. Due to the state of the trash and burn piles on the property,it was impossible to determine <br /> what may have been disposed or burned. There is potential for surface water runoff, which could <br /> contain contaminants,to leach into the soils of the subject property.This can adversely impact soil and <br /> water quality. <br /> 5.0 CONCLUSIONS AND RECOMMENDATIONS <br /> A. Given the historical uses of agricultural chemicals and petroleum products on the subject <br /> property,meaningful conclusions regarding the presence or extent of such material cannot be <br /> determined without soil sampling and analysis. Such sampling and analysis is especially <br /> warranted when agricultural land is converted into residential use,as is the case on this property. <br /> B. Should the property owners or the EHD be concerned about the area of trash and burn piles <br /> on the north side of the subject property, soil and water tests are recommended to determine <br /> if there are any contaminants that may adversely affect the subject property. As the site is <br /> developed, any sources of contamination identified, including the debris pile, should be <br /> removed and disposed of in accordance with all applicable EHD rules and regulations. <br /> C. Should the future residents of the subject property be interested in determining the quality of <br /> their drinking water,EHD should be contacted for direction regarding the potential for impacts <br /> to groundwater from the agricultural history of the property and vicinity. <br /> 6.0 LIMITATIONS <br /> This report was compiled as a Surface and Subsurface Contamination Report for the subject property. <br /> This report contains information and data provided to NOA by several sources.
