• Determination of the Direction of Groundwater Flow <br /> and <br /> Flow Rate <br /> at the <br /> Pestana Trust Property <br /> 275 Grant Line Road, Tracy, CA <br /> The flow of water in a saturated porous medium such as soil <br /> is defined by Darcy's Law. This law states that under <br /> saturated conditions , the volume of water flowing per unit <br /> area, per unit time (Q/At=v) is directly proportional to <br /> the product of hydraulic conductivity (K) of that soil and <br /> the hydraulic gradient (h/L) ; <br /> v=K h/L <br /> Measurements acquired at the site during the past five <br /> monitoring events appear in Tables 1, 2 , 3, 4, and 5 : <br /> Table 1 <br /> Well Head Elevations and Depth to Groundwater at 275 Grant <br /> • Line Road, Tracy, CA, November 23 , 1993 <br /> Well Head Depth to Relative Groundwater <br /> Well Elevation* Groundwater Elevations <br /> Number (ft) (ft) ( ft) <br /> ----------------------------------------------------------- <br /> MW--1 60 . 51 8 . 10 52 . 41 <br /> MW-2 59. 40 7 . 10 52 . 30 <br /> MW-3 60 .05 7 . 56 52 . 49 <br /> Table 2 <br /> Well Head Elevations and Depth to Groundwater at 275 Grant <br /> Line Road, Tracy, CA, February 14, 1994 <br /> Well Head Depth to Relative Groundwater <br /> Well Elevation* Groundwater Elevations <br /> Number (ft) (ft) (ft) <br /> ----------------------------------------------------------- <br /> MW-1 60 . 51 7 . 77 52 . 74 <br /> MW-2 59 . 40 6 . 80 52 . 60 <br /> MW-3 60 . 05 7 . 36 52 . 69 <br /> • <br />
