(Sierra-Pacific) has been monitoring shallow ground water at <br /> 2130 West Washington Street, Stockton on behalf of Unocal since 1993. On the basis,of five years of ground <br /> water investigations, it would appear that molasses-based feed product concentrations known to be present <br /> beneath the Washington Street facility have had little or no deleterious effect on near-surface ground water <br /> resources. The hydrogeologic regime may be complex,and the lack of significant ground water impact may ` <br /> seem enigmatic,but the facts of the case seem undeniable. <br /> .We believe that no further investigation is needed at Washington Street because very little has changed in five <br /> years of monitoring. If you are not comfortable with certain issues,we would be glad to visit your office to <br /> discuss technical issues. = <br /> Sincerely, <br /> SIERRA-PACIFIC GROUNDWATER CONSULTANTS,INC. <br /> .
