i <br /> 12-07-94 PHS/EHD receives the"Addendum to the Summary of Investigative Findings and Closure <br /> Report' dated November 30, 1994. The addendum reports additional information on the <br /> f estimate of residual soil contamination remaining, the fate of the contamination in the soil, <br /> the estimate of residual groundwater contamination remaining (1,2 DCA), the fate and <br /> transport of the remaining 1,2 DCA, the potential sources to the PCE contamination noted <br /> in the wells nearest the street. The report also piesents the monitoring and sampling <br /> results of the six site wells for the fourth quarter 19946 and the conclusion that closure <br /> is warranted at this time. <br /> The six site wells were monitored and sampled on`Naveniber 24, 1994. Depth to water <br /> was approx. 71.89' to 74.62' bgs with no flow direction being reported. The wells were <br /> purged with a vacuum pump in an attempt to bring down the water table below the screen <br /> portion of the well as water levels have risen. Water in MW#1, MW#2, and MW#3 was <br /> drawn down into the screen interval area during purging, .but not in MW#4, MW#5, and <br /> MVM. All six wells did not show petroleum contaniinatiori except for 1,2 DCA in MW#2 <br /> and MW#5 and PCE in MW#4, MW#5, and MW#6. <br /> I <br /> 02-15-95 The site is again presented at a TRC meeting with the atldibonal data and information <br /> presented. The TRC votes to process site for regulatory closure. <br /> it <br /> I <br /> 3 <br /> i} <br /> .i <br /> I' <br /> IN <br /> ,l <br /> a� <br /> I I <br /> ,i <br /> I} <br /> i <br /> E <br /> I� <br /> IY <br /> Ik <br /> .r <br /> it <br /> I} <br /> 5 For historical groundwater analytical results, please refer,,I:to end of chronology. <br /> I <br /> I .0 <br /> 1 D <br />
