This probe continues to be sampled thereafter. <br /> See Appendix J for gas composition at all soil gas probes <br /> NS = Not sampled, not selected for TO-15 monitoring <br /> NR= Not Reported <br /> Harney Lane Sanitary Landfill Department of Public Works/Solid Waste <br /> 2n°Semester and Annual 2012 Groundwater Monitoring Report County of San Joaquin—January 25,2013 <br />
