The <br /> Addendum addresses the items that California Regional Water Quality Control Board, Central <br /> Valley Region (Central Valley Water Board) staff requested in its 30 September 2009 <br /> conditional concurrence letter referencing the 7 July 2009 Site Characterization Work Plan <br /> Phase II. <br /> In the November Addendum, one of the shallow borings at the Western Surface Water Sump <br /> will be turned into a deep monitoring well, and the deep boring at the eastern concrete <br /> ponds will be completed as a deep monitoring well. These deep monitoring wells will <br /> extend to about 190 feet, comparable with the depth of the on-site supply well. The <br /> addendum also presents well installation descriptions for these monitoring wells and for <br /> the aquifer test well. <br /> In addition, the Addendum proposes additional samples from the shallow and the deeper <br /> water bearing zones to be collected for isotope analyses. <br /> Central Valley Water Board staff concur with the November Addendum. <br /> A copy of the November Addendum is being posted onto the Geotracker website and may be <br /> viewed at www.geotracker.waterboards.ca.gov. Click on Tools/Advanced Search, type in the <br /> site/facility name of Ripon Farm Service (leave the other fields blank) , and ensure that <br /> the 'Other Water Board Cleanup Sites' box is checked.
