The three monitor wells will yield data for ground water <br /> gradient, flow direction and ground water quality. If this approach meets <br /> with your approval WA and PI will proceed. If you have any questions or <br /> comments please let us know. <br /> Sincerely, <br /> Weiss Associates <br /> Sherwood Lovejoy, Jr. <br /> Project 4ydrogeologist <br /> i <br /> r <br /> SL:ja <br /> cc: Nick Bokides, PI i . <br /> Jack Fiori, San Joaquin Mosquito Abatement <br /> i <br /> S <br /> r <br /> ,a <br /> s <br /> r <br />
