Ms. Jeanne Zolezzi <br /> April 12, 1996 <br /> Page 4 of 4 <br /> Recommendations <br /> Because there is no evidence that operations on the property have contributed to the poor <br /> i regional water quality and there are no increasing or decreasing trends in the well chemistry <br /> data in over five years of monitoring additional well ',sampling is unlikely to further our <br /> understanding of the site. Given the discontinuation of pickling operations and the fact that <br /> this portion of Stockton is not a rainwater recharge ar 'e!a it is unlikely that the salt present <br /> in the shallow low permeablility soils will migrate. Additionally, since these wells could <br /> potentially serve as conduits for the introduction of contaminants to the shallow groundwater <br /> zone it is recommended that wells MW-6, MW-7 and MW-8 be abandoned. <br /> Considering the total time operations . occurred on site (since 1977) any significant <br /> mobilization of salt in the soils would probably already 11have occurred. Current operations <br /> are unlikely to have any impact on salt migration. While covering of the site with an asphalt <br /> surface would provide an additional measure of protection it is not critical at this time. A <br /> more important consideration would be the development of a drainage plan which prevents I <br /> r off-site runoff from coming onto the site, particularly from the adjacent Londen Produce <br /> operation. No other special considerations should '�be required other than standard <br /> 4 <br /> j prevention of repeated flooding or creating prolonged ''standing water conditions. <br /> If you would like to discuss this site or any specific recommendations please contact me at j <br /> your convenience. <br /> Respectfully, <br /> L <br /> Russell W.
