MW-4C The groundwater monitored by the well <br /> has been ND for MTBE. This deeper- <br /> screened well passes through the <br /> contaminated water monitored by MW- <br /> 4A,therefore the evaluation of issues <br /> related to MW-4A apply to well MW-4C. <br /> Variance requested to be allowed to destroy <br /> well by pressure grouting due to: <br /> Traffic safety, EHD found the well is located in a hotel <br /> parking lot with no unusual traffic issues. <br /> Business convenience. Removal of the well will cause some <br /> inconvenience for the hotel and guests, <br /> but no more than when the well was <br /> installed. <br /> MW-7A The last monitoring event had MTBE <br /> contaminated groundwater and no post- <br /> remedlation samples were collected to <br /> demonstrate contaminant concentrations <br /> to be below the laboratory detection <br /> limit. <br /> Variance requested to be allowed to destroy <br /> well by pressure grouting due to: <br /> Traffic safety, EHD found the well is in a hotel parking <br /> lot with no unusual traffic issues. <br /> Business convenience, Work required for proper destruction of <br /> this well should not directly impact the <br /> convenience of local businesses or their <br /> customers. <br /> Trend analysis shows MTBE will not be Trend analysis is based on data collected <br /> detected in MW-7A watersomples by June during GWE, and may not be applicable <br /> 2011, to natural conditions without GWE. <br /> Nearby extraction well EW-6A was ND for The wells had four contemporaneous <br /> MTBE when it was last sampled, therefore sampling events with the results as <br /> shown below.
