Followin ' <br /> determination of the status of thewill` <br /> g`' <br /> groundwater at the site, we will�,� <br /> propose any necessary remediation measures for review by the San" <br /> Joaquin County Environmental Health Division and the Central l' <br /> Valley Regional Water Quality Control Board.
