MTBE was detected <br /> at 5.0 }tg/l in MW-2. 1,2-DCA was detected in groundwater samples from three wells at <br /> concentrations ranging from 3.4 to 310 gg/l. Ther sults of this investigation are documented in <br /> Cambria's May 2,2003 Site Investigation/Quarterly Monitoring Report-First Quarter 2003. <br /> Groundwater Monitoring and Sampling: The nine existing groundwater monitoring wells have <br /> been monitored and sampled quarterly since they were installed.
