MW-7A MW-7A is probably ND too. micrograms per liter: <br /> (Continued) EW-6A MW-7A <br /> 6/17/2009 j 1070 1710 <br /> 111/19/2009 390 1200 <br /> 5/12/2010 <1 330 <br /> j 12/27/2010 23 30 1 <br /> 6/29/2011 <1 ?y <br /> The table shows a weak correlation of the <br /> results from the two wells,and an ND in <br /> EW-6A does not necessarily mean an ND <br /> in the un-sampled MW-7A,as shown by <br /> the results for 5/12/2010.The results <br /> suggest that the MTBE concentrations in <br /> MW-7A are consistently higher than <br /> obtained from EW-6A when sampled at <br /> the same time.The EHD concludes that <br /> there is a reasonable suspicion that MW- <br /> 7A is in an area of contamination and <br /> that the well must be destroyed by <br /> removing the well contents. <br /> MW-713 Groundwater monitored by the well has <br /> been ND for MTBE, this deeper screened <br /> well passes through the contaminated <br /> groundwater monitored by MW-7A; <br /> therefore,the evaluation of issues <br /> related to MW-7A apply to well MW-76 <br /> and the well contents should be removed <br /> for proper destruction. <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 /> well should not impact the business. <br /> Page 4 of 9 <br />
