[61 Continued. <br /> With respect to the protection of the underlying groundwater from pathogens and nitrates (NO,), the <br /> depth to groundwater(55 ft), and the low density housing can be considered favorable for prevention <br /> of nitrate contamination. It appears agricultural practices have not influenced the nitrate groundwater <br /> concentration of the aquifer(s) which serve the irrigation well. Attached well logs from the <br /> Environmental Health Department indicate there are sufficient clay layers between grade and the <br /> depth to groundwater to have some attenuation effect on the downward migration of nitrate <br /> molecules. <br /> [71 LIMITATIONS <br /> The conclusions of this Soil Suitability Study are based upon current information concerning the <br /> location and results of the percolation testing, and the highest anticipated depth to groundwater. The <br /> results of the percolation testing can only be assumed to represent the subsurface conditions <br /> encountered in the area of testing. <br /> It is our opinion that the findings included in this study is a reasonable assessment of the current <br /> subject property conditions. This opinion cannot constitute a guarantee or warranty, either expressed <br /> or implied. <br /> Respectfully submitted, <br /> QUALITY CONTROL INSPECTION, INC. <br /> Don Chesney, R.E.A.
