For instance, reliable ground water <br /> gradients cannot be computed from your wells. We have discussed <br /> this with the San Joaquin Local Health District (District) and <br /> agree that the gradient at your site is probably not toward the <br /> south because all other investigations in Tracy show shallow <br /> ground water gradients toward the north. We also don't agree <br /> with your report. that the water at approximately twelve feet is <br /> perched because this same layer is found throughout the Tracy <br /> area. <br /> Permits are required from the San Joaquin Local Health District _ <br /> (SJLHD) prior to any subsurface -investigations. Also be advised <br /> that not only are proper well completion diagrams necessary in <br /> the PAR but they must be submitted to the SJLHD when applying for <br /> a permit to install monitoring wells. <br /> Please have your consultant prepare a completed Problem <br /> Assessment Report (reporting requirements enclosed) and submit it <br /> to the District and this office by t <br /> If you have any questions <br /> please call me at (916) 361-5731. <br /> GARY S.
