(AUS) prepared this letter report on behalf of Forward Incorporated (Forward)to <br /> summarize water quality monitoring results for samples collected from the well used to supply <br /> groundwater for the property located at 3447 Sunny Road, Stockton, CA 95215 (Figure 1).The <br /> samples were collected as part of the domestic well sampling program being performed under the <br /> direction of the Central Valley Regional Water Quality Control Board (CVRWQCB) of the State Water <br /> Resources Control Board to better understand the groundwater quality in the area and help <br /> evaluate the progress of an on-going groundwater investigation for the Forward Landfill. <br /> As you may know, Forward acquired the City of Stockton's landfill in 2000. As a condition of that <br /> acquisition, Forward agreed to address existing and potential future groundwater contamination <br /> caused by the City's landfill operations, which go back to 1954. Since that acquisition, Forward has <br /> been working cooperatively with the CVRWQCB to conduct groundwater investigations and to <br /> control and reduce identified volatile organic compounds associated with the landfill.Together, <br /> Forward and the CVRWQCB continue to proactively monitor and sample groundwater wells at <br /> several residential properties located near the landfill. <br /> SAMPLING AND ANALYSIS <br /> On September 18, 2023, a representative of Forward visited the property at the address identified <br /> above and received permission from you to participate in the domestic well sampling program. After <br /> receiving permission, a groundwater sample was collected from the hose bib on the front of the <br /> house.The well sampling data sheet and laboratory report are attached. <br /> Approximately 70 gallons of water was discharged from the sample point prior to collecting the <br /> groundwater sample. Before collecting the sample,the temperature, pH, and conductivity of the <br /> groundwater were measured and recorded on the well sampling data sheet. After these <br />
