On July 20, 2011, V&W Drilling (C57 #720904) destroyed monitoring well MW-BR under the supervision of Mr. Joe Vasquez, a Ground Zero Geologist. The depth to bottom of the monitoring well was measured to insure no obstructions were present. The well was over-drilled using 8-inch diameter hollow stem augers center overthe well casing using a guide rod. After the well was over-drilled the guide rod was removed`and the 2-inch- diameter -inchdiameter well casing pulled from the borehole. The boring was grouted with neat cement gout, through the augers grade level. No water was displaced during well destruction activities. Surface completion consisted of native fill to match the existing surface. All soil generated during the destruction of well was spread on the dirt lot.
