This report presents the results from the third quarter <br /> monitoring and sampling event. Currently, five groundwater monitoring wells are being used to <br /> evaluate hydrologic and water-quality conditions at the site. Pertinent site features and the <br /> locations of monitoring wells are shown on Figure 2. <br /> BACKGROUND <br /> SITE DESCRIPTION AND USE <br /> The site is located at 35275 Welty Road,Vernalis, San Joaquin County, California. Currently,a <br /> paper insulation manufacturer,Insulair Inc., occupies the site. The site formerly belonged to a <br /> container manufacturer, Hunter Container Company,and a can manufacturer,U. S. Can <br /> Company. The site is located in a rural and light-industrial area and is bordered by Welty Road <br /> on the east,Highway 33 on the north, and agricultural fields south and west of the site. The site <br /> location is presented on Figure 1. <br /> The site is located within the Central Valley Physiographic Province of California and has a <br /> relatively flat topography that slopes gently downward to the northeast. The site is situated at an <br /> elevation of approximately 103 to 105 feet above mean sea level(MSL). <br /> From the early 1900s to the 1960s Standard Oil(predecessor to Chevron)operated the former Old <br /> Valley Pipeline (OVP),which transported heated heavy petroleum(crude oil and Bunker C fuel <br /> oil)from Bakersfield to Richmond, California. The OVP was located along the northeastern side <br /> of the site and parallel to the existing Union Pacific Rail Road(UPRR)tracks and Highway 33. <br /> 3800 Watt Avenue,Suite#210, Sacramento, CA 95821(916)974-8800 'Fax:(916)979-3735 <br />
