Nestle USA Inc. • - 7 - • 16 June 2005 <br /> 19. Figures 4-1 through 4-4 and 5-1 through 5-4: Pumping rates at municipal well MW-10 varied <br /> greatly in 2004,but the interpretation of the pumping depression caused by this supply well is <br /> essentially the same for all four quarters in 2004. Nestle needs to interpret how the pumping <br /> changes may have affected the groundwater potentiometric surfaces in the Intermediate and Lower <br /> Aquifers and revise these figures. <br /> Also,please explain how Nestle can use water level data from Ripon's monitoring well MW-1 Omon <br /> if the screen interval for this well is unknown(see Table 1). If this data can not be assigned to a <br /> particular aquifer, then interpretation may be impossible. Although collecting depth to water <br /> readings from the adjacent municipal supply well (MW-10)may be difficult,Nestle should attempt <br /> to do this each quarter. <br /> Please address our general and specific comments and submit the Final Annual Report by 19 August <br /> 2005. If you have any questions about this letter or would like to schedule a meeting to discuss these <br /> comments, please contact me at (916) 464-4733 (mnierceOwaterboards.ca.govl. <br /> Marcus L.
