Quik Market#39 Page 2 2285 E. Fremont Street February 7, 2008 Stockton, CA MW-3 or site conditions change abruptly. The report of findings for the southerly investigation may include this recommendation if applicable. The EHD requires that groundwater samples from MW-1,. MW-2 and MW-3 be analyzed quarterly for 1,2-DCA and will allow semi-annual analysis for total petroleum-hydrocarbons as gasoline (TPHg). If both analytes stay at approximately the same concentrations or decrease, the TPHg analysis may be dropped until the last two quarters before a "no further action" is approved by the EHD. The EHD notes that the TPHg and 1,2-DCA concentrations are nearly the same; if you show that the TPHg is actually.1,2-DCA, the.TPHg analyses can be dropped until the final monitoring events prior to site closure. Analyses for benzene, toluene, ethylbenzene, and xylene (BTEX) and the oxygenates for MW-1 through MW-3 may be dropped at this time. After the dissolved plume has been fully delineated and the groundwater data clearly demonstrates declining contaminant concentrations, the EHD will again evaluate this site for a no further action" status.
