The second issue pertains to the scientific study of the magnitude and environmental impact of <br /> pond seepage. In a Virginia study of a swine pond located in a poorly drained and high water <br /> table soil (as is the subject ranch), there was pollutant movement at a distance of 3 meters from <br /> the pond but none at 15 meters (Collins, et al., 1975). <br /> In summary, although there is seepage of the pond(s), it is our opinion the seepage is <br /> comparatively low considering the data obtained from this study, particularly the Ec <br /> measurement between the ponds and groundwater adjacent to the ponds. It appears that high <br /> TDS water is indigenous to this area, but the pond may also be contributing an indeterminate <br /> amount of TDS to the surrounding groundwater. However, the subject ponds remain the most <br /> efficient manure management design for this ranch. <br /> LIMITATIONS <br /> This study represents conclusions drawn from the best available technology, knowledge and <br /> analytical methods. Quality Control Inspection, Inc. cannot definitively determine nor guarantee <br /> that the ponds do not, or will not have any environmental impact upon the underlying soil and <br /> groundwater. Although the soil on the bottom of the subject pond could not be sampled and <br /> hydrometer tested, from the soil boring test results, it can be reasonably assured the soil <br /> underlying the pond exceeds current State regulations for clay content. <br /> Respectfully submitted, <br /> ' QUALITY CONTROL INSPECTION, INC. <br /> Z,,.- -'e7 <br /> Don Chesn , R.E.A. ess Wry, P.E. <br /> �� *ality Control Inspection <br />
