During <br /> pumping of the recovery well at a rate of 5 to 6 gpm, the groundwater movement in the area of <br /> the site is towards the recovery well. The area influenced by the pumping appears to extend off <br /> site in all directions. <br /> Please direct any questions regarding this project to me at(916) 444-0123. <br /> Very truly yours, <br /> BROWN AND CALDWELL <br /> Patti De La O <br /> `,— Project Manager <br /> PYD:SP:n;kw <br /> Enclosure <br /> cc/enc: Ms. Laurie.Cotulia, San Joaquin County Health Department <br /> Ms. Patti De La G, Brown and Caldwell <br /> Mr. John Randall,Chevron <br /> Mr. Chris Winsor,ARCO Products Company <br /> } <br /> Brawn and Caldwell <br /> Consultanis <br />
