Monitor the depth to water in all groundwater monitoring wells quarterly to determine <br /> the groundwater gradient. <br /> 2. Collect groundwater samples for laboratory analysis of total petroleum hydrocarbons <br /> as gasoline and diesel (TPHg and TPHd), benzene, toluene, ethylbenzene and <br /> xylenes from monitoring wells MW-2A and MW-5 on a quarterly schedule. <br /> 3. Collect groundwater samples for laboratory analysis of the above listed constituents <br /> from the domestic wells at addresses 5157 and 5055 W. Business Loop 205 on a <br /> semi-annual schedule. <br /> 4. Collect groundwater samples for laboratory analysis of the above listed constituents <br /> from all twelve groundwater monitoring wells on an annual schedule. <br /> 5. Discontinue laboratory analysis of all fuel oxygenates and lead scavengers. <br /> In discussion with AGE it was proposed that the annual sampling of all wells will occur during <br /> the third quarter of the year. It was also noted that the owner of the domestic well located at <br /> 5225 W. Business Loop 205 has refused access to allow this well to be sampled. Should <br /> access to this well be obtained in the future, the well should be added to the semi-annual <br /> sampling schedule. If you have any questions please call Lori Duncan at (209)468-0337. <br /> Sincerely, <br /> 1-5 <br /> Lori Duncan, REHS Nuel C.
