5.0 CONCLUSIONS AND RECOMMENDATIONS <br /> The conclusions of the investigation are as follow: <br /> 1. Analytical laboratory results from water and soil sampling at the St. Francis Motel site <br /> have indicated that chemicals commonly associated with illegal drug lab operations are <br /> not currently present in the effluent or soil beneath the septic system at concentrations <br /> that are considered as hazardous levels as defined by California or federal law. No threat <br /> to underlying groundwater is present based on soil sampling results. <br /> 2. Acetone, chloride and 2-butanone(MEK)were found at trace concentrations in both soil <br /> and effluent samples. These substances may or may not have originated from illegal drug <br /> lab waste product being disposed of in the motel septic system. These chemicals could <br /> potentially have originated from disposal of cleaning agents or other household products <br /> that have left trace concentrations of these chemicals in the soil and effluent. <br /> 3. The motel septic system is currently well documented by maps and photographs. The <br /> system is currently working better than it has in quite some time. <br /> 4. All aspects of the motel septic system currently meet code for San Joaquin County <br /> requirements. <br /> The recommendations of this report are as follow: <br /> 1. The St. Francis Motel has met all of the requirements that PHSEHD has directed for <br /> completion of the soil investigation. The site can be closed as this time as no further <br /> action is warranted. <br /> Main\Environmentallst.FrancisMotel\Report\Report05252006.wpd 17 <br />
