Steve Schneider <br /> R- . uartc � Repart E..YON Station , 749 E . Charter Way , Stnck_ton , <br /> Ca . <br /> On October 1 , 1990 , Twining Laboratories attemped to sample the <br /> monitoring wells at this site . Attached is a copy of their <br /> findings . <br /> As can be seen the wells were dry due to the summer drawdown in <br /> this area caused by pumping . Although the wells were drilled and <br /> eased 10 + feet below the water table in January , this distance <br /> was not enough to compensate for the drawdown . <br /> We have obtained a few water table reports of the Stockton area <br /> and find drawdowns of over 15 feet to be common . However , in all <br /> cases the water table recovers to near its previous position . We <br /> therefore , feel the water will be measurable at the next <br /> quarterly sampling in January 1991 . <br /> Yours truly , <br /> John Cussen <br /> Calif . Reg .
