The southwest portion of the <br /> _ >` WWTP is shown in the aerial <br /> photograph to the left. The <br /> area west of Holly Drive was <br /> go.L. removed from background <br /> ' • { 'T_ '� " ' well location consideration <br /> because of the extensive light <br /> =i=?'

The <br /> City does not own any <br /> 9rtri.• ` T property between I-205 and <br /> West Larch Road. Installation <br /> x" of a background well in this <br /> area would require obtaining <br /> an agreement for well <br /> installation and continued <br /> City access to the monitoring <br /> well for routine sampling. <br /> Installing a well along the Holly <br /> Drive easement is not possible <br /> because Holly Drive is elevated <br /> immediately south of West Larch , <br /> Road(see photograph at right). F <br /> There is not enough room between "+ <br /> the raised road bed and the + <br /> residential property line for vehicle Y <br /> access. In addition,there are <br /> overhead power lines along the <br /> property line that could make <br /> monitoring well installation <br /> difficult. - <br /> Because of the difficulty in - <br /> identifying alternate background <br /> well locations,the City requests <br /> the CVRWQCB approve one of <br /> two approaches: <br /> 1. Proceed with the installation of a background well at the proposed location. If the <br /> CVRWQCB is not satisfied that this well would be considered'background',then this <br /> well would not be installed. <br /> 2. Consider BW-2 and BW-6 as background wells. As discussed above,these wells would <br /> be sampled every quarter during the next two years to increase the background data to <br />
