Gravelly loose sand layers have been reported based on CPT <br /> soundings at approximately 25 to 45 feet,70 to 75 feet, 82 to 90 feet,and 130 to 150 feet bsg <br /> depth. The report categorized these units as pant Water Zow,Ste[WaterZr»� 7W Water <br /> Zwr, and Pn»uryA r207M. It is unlikely that there are any true confining barriers between <br /> these water zones. It is also unknown if there are any drawdown effects resulting from <br /> Pumping of local municipal water wells. <br /> A Division of San Joaquin County Health Care Services <br />
