The GHD tables should be updated to include missing data. <br />Offsite Water Wells <br />Additional work should be conducted to identify any other water supply wells in the immediate <br />vicinity and ensure residences located near the site are connected to a water service. <br />GHD will plan to complete a door-to-door survey to identify any other water supply wells in the <br />immediate vicinity. <br />GHD will contact California Water Service of Stockton to determine if all local residences are <br />currently connected to the municipal water supply. <br />CVRWQCB staff will review existing well logs. <br />A Zone Well Destruction <br />GHD will review historical data to determine if any further groundwater analytical data is needed to <br />define the extent of the release in A Zone wells. <br />If no further data is necessary, GHD will propose destruction of A Zone wells. <br />Work Plan Addendum <br />GHD will present the findings and propose work described above in an addendum report to the <br />November 30, 2020 Well Installation Work Plan by Arcadis. <br />11193145-Agency Meeting Notes.docx
